20-year trajectories of positive and negative symptoms after the first psychotic episode in patients with schizophrenia spectrum disorder: results from the OPUS study

This study aimed to identify the 20-year trajectories of positive and negative symptoms after the first psychotic episode in a sample of patients with an ICD-10 diagnosis of schizophrenia spectrum disorder, and to investigate the baseline characteristics and long-term outcomes associated with these trajectories. A total of 373 participants in the OPUS trial were included in the study. Symptoms were assessed at baseline and after 1, 2, 5, 10 and 20 years using the Scales for the Assessment of Positive and Negative Symptoms. We used latent class growth mixture modelling to identify trajectories, and multinominal regression analyses to investigate predictors of membership to identified trajectories. Five trajectories of positive symptoms were identified: early continuous remission (50.9% of the sample), stable improvement (18.0%), intermittent symptoms (10.2%), relapse with moderate symptoms (11.9%), and continuous severe symptoms (9.1%). Substance use disorder (odds ratio, OR: 2.83, 95% CI: 1.09-7.38, p=0.033), longer duration of untreated psychosis (OR: 1.02, 95% CI: 1.00-1.03, p=0.007) and higher level of negative symptoms (OR: 1.60, 95% CI: 1.07-2.39, p=0.021) were predictors of the relapse with moderate symptoms trajectory, while only longer duration of untreated psychosis (OR: 1.01, 95% CI: 1.00-1.02, p=0.030) predicted membership to the continuous severe symptoms trajectory. Two trajectories of negative symptoms were identified: symptom remission (51.0%) and continuous symptoms (49.0%). Predictors of the continuous symptoms trajectory were male sex (OR: 3.03, 95% CI: 1.48-6.02, p=0.002) and longer duration of untreated psychosis (OR: 1.01, 95% CI: 1.00-1.02, p=0.034). Trajectories displaying continuous positive and negative symptoms were linked to lower neurocognition, as measured by the Brief Assessment of Cognition in Schizophrenia (BACS) (z-score: –0.78, CI: –1.39 to –0.17, for continuous positive symptoms; z-score: –0.33, CI: –0.53 to –0.13, for continuous negative symptoms). The same trajectories were also linked to higher use of antipsychotic medication at 20-year follow-up (continuous positive symptoms: 78%; continuous negative symptoms: 67%). These findings suggest that the majority of patients with first-episode schizophrenia spectrum disorder have a trajectory with early stable remission of positive symptoms. Long duration of untreated psychosis and comorbid substance abuse are modifiable predictors of poor trajectories for positive symptoms in these patients. In about half of patients, negative symptoms do not improve over time. These symptoms, in addition to being associated with poor social and neurocognitive functioning, may prevent patients from seeking help.     

The clinical significance of duration of untreated psychosis: an umbrella review and random‐effects meta‐analysis

The idea that a longer duration of untreated psychosis (DUP) leads to poorer outcomes has contributed to extensive changes in mental health ser­vices worldwide and has attracted considerable research interest over the past 30 years. However, the strength of the evidence underlying this notion is unclear. To address this issue, we conducted an umbrella review of available meta‐analyses and performed a random‐effects meta‐analysis of primary studies. MEDLINE, Web of Science, PsycINFO and EMBASE were searched from inception to September 3, 2020 to identify relevant meta‐analyses of studies including patients with schizophrenia spectrum disorders, first‐episode psychosis, or affective and non‐affective psychosis. Thirteen meta‐analyses were included, corresponding to 129 individual studies with a total sample size of 25,657 patients. We detected potential violations of statistical assumptions in some of these meta‐analyses. We therefore conducted a new random‐effects meta‐analysis of primary studies. The association between DUP and each outcome was graded according to a standardized classification into convincing, highly suggestive, suggestive, weak, or non‐significant. At first presentation, there was suggestive evidence for a relationship between longer DUP and more severe negative symptoms (beta=–0.07, p=3.6×10^–5) and higher chance of previous self‐harm (odds ratio, OR=1.89, p=1.1×10^–5). At follow‐up, there was highly suggestive evidence for a relationship between longer DUP and more severe positive symptoms (beta=–0.16, p=4.5×10^–8), more severe negative symptoms (beta=–0.11, p=3.5×10^–10) and lower chance of remission (OR=2.16, p=3.0×10^–10), and suggestive evidence for a relationship between longer DUP and poorer overall functioning (beta=–0.11, p=2.2×10^–6) and more severe global psychopathology (beta=–0.16, p=4.7×10^–6). Results were unchanged when analysis was restricted to prospective studies. These effect sizes are clinically meaningful, with a DUP of four weeks predicting >20% more severe symptoms at follow‐up relative to a DUP of one week. We conclude that DUP is an important prognostic factor at first presentation and predicts clinically relevant outcomes over the course of illness. We discuss conceptual issues in DUP research and methodological limitations of current evidence, and provide recommendations for future research.     

Antipsychotic augmentation vs. monotherapy in schizophrenia: systematic review,meta‐analysis and meta‐regression analysis

Antipsychotic polypharmacy in schizophrenia is much debated, since it is common and costly with unclear evidence for its efficacy and safety. We conducted a systematic literature search and a random effects meta‐analysis of randomized trials comparing augmentation with a second antipsychotic vs. continued antipsychotic monotherapy in schizophrenia. Co‐primary outcomes were total symptom reduction and study‐defined response. Antipsychotic augmentation was superior to monotherapy regarding total symptom reduction (16 studies, N=694, standardized mean difference, SMD=–0.53, 95% CI: ?0.87 to ?0.19, p=0.002). However, superiority was only apparent in open‐label and low‐quality trials (both p<0.001), but not in double‐blind and high‐quality ones (p=0.120 and 0.226, respectively). Study‐defined response was similar between antipsychotic augmentation and monotherapy (14 studies, N=938, risk ratio = 1.19, 95% CI: 0.99 to 1.42, p=0.061), being clearly non‐significant in double‐blind and high‐quality studies (both p=0.990). Findings were replicated in clozapine and non‐clozapine augmentation studies. No differences emerged regarding all‐cause/specific‐cause discontinuation, global clinical impression, as well as positive, general and depressive symptoms. Negative symptoms improved more with augmentation treatment (18 studies, N=931, SMD=–0.38, 95% CI: ?0.63 to ?0.13, p<0.003), but only in studies augmenting with aripiprazole (8 studies, N=532, SMD=–0.41, 95% CI: ?0.79 to ?0.03, p=0.036). Few adverse effect differences emerged: D2 antagonist augmentation was associated with less insomnia (p=0.028), but more prolactin elevation (p=0.015), while aripiprazole augmentation was associated with reduced prolactin levels (p<0.001) and body weight (p=0.030). These data suggest that the common practice of antipsychotic augmentation in schizophrenia lacks double‐blind/high‐quality evidence for efficacy, except for negative symptom reduction with aripiprazole augmentation.     

Impact of assessment and intervention by a health and social care professional team in the emergency department on the quality,safety, and clinical effectiveness of care for older adults: A randomised controlled trial

BackgroundOlder adults frequently attend the emergency department (ED) and experience high rates of adverse events following ED presentation. This randomised controlled trial evaluated the impact of early assessment and intervention by a dedicated team of health and social care professionals (HSCPs) in the ED on the quality, safety, and clinical effectiveness of care of older adults in the ED.Methods and findingsThis single-site randomised controlled trial included a sample of 353 patients aged ≥65 years (mean age = 79.6, SD = 7.01; 59.2% female) who presented with lower urgency complaints to the ED a university hospital in the Mid-West region of Ireland, during HSCP operational hours. The intervention consisted of early assessment and intervention carried out by a HSCP team comprising a senior medical social worker, senior occupational therapist, and senior physiotherapist. The primary outcome was ED length of stay. Secondary outcomes included rates of hospital admissions from the ED; hospital length of stay for admitted patients; patient satisfaction with index visit; ED revisits, mortality, nursing home admission, and unscheduled hospital admission at 30-day and 6-month follow-up; and patient functional status and quality of life (at index visit and follow-up). Demographic information included the patient’s gender, age, marital status, residential status, mode of arrival to the ED, source of referral, index complaint, triage category, falls, and hospitalisation history. Participants in the intervention group (n = 176) experienced a significantly shorter ED stay than the control group (n = 177) (6.4 versus 12.1 median hours, p < 0.001). Other significant differences (intervention versus control) included lower rates of hospital admissions from the ED (19.3% versus 55.9%, p < 0.001), higher levels of satisfaction with the ED visit (p = 0.008), better function at 30-day (p = 0.01) and 6-month follow-up (p = 0.03), better mobility (p = 0.02 at 30 days), and better self-care (p = 0.03 at 30 days; p = 0.009 at 6 months). No differences at follow-up were observed in terms of ED re-presentation or hospital admission. Study limitations include the inability to blind patients or ED staff to allocation due to the nature of the intervention, and a focus on early assessment and intervention in the ED rather than care integration following discharge.ConclusionsEarly assessment and intervention by a dedicated ED-based HSCP team reduced ED length of stay and the risk of hospital admissions among older adults, as well as improving patient satisfaction. Our findings support the effectiveness of an interdisciplinary model of care for key ED outcomes.Trial registrationClinicalTrials.gov {"type":"clinical-trial","attrs":{"text":"NCT03739515","term_id":"NCT03739515"}}NCT03739515; registered on 12 November 2018.

Comparison of outcomes of percutaneous coronary intervention on proximal versus non-proximal left anterior descending coronary artery, proximal left circumflex, and proximal right coronary artery: A cross-sectional study

Background

There have been few prospective studies examining the utility of routine exercise treadmill testing (ETT) early after percutaneous coronary intervention (PCI). The objective of this study was to examine the impact of a routine ETT strategy early after PCI on follow-up cardiac events and procedures.

Methods

We examined 136 patients who underwent routine ETT at 6 weeks post-PCI in the ADORE trial. The ETT was classified as positive, indeterminate, or negative. The Duke Treadmill Score (DTS) was calculated for all patients. Follow-up occurred at 9 months.

Results

ETT results at 6 weeks were: 32 (23.5%) positive, 24 (17.6%) indeterminate and 80 (58.8%) negative. At 9 months, the composite event rate was 21.9% in those with a positive ETT, 20.8% in those with an indeterminate ETT and 12.5% in those with a negative ETT (p = 0.25 positive vs. negative ETT). The sensitivity of early ETT for predicting clinical events was 41.2%, the specificity was 73.3%, the positive predictive value was 21.9% and the negative predictive value was 87.5%. At 9 months, the cardiac procedure rate was 18.8% in those with a positive test, 13.0% in those with an indeterminate test, and 6.3% in those with a negative test (p = 0.07 positive vs. negative ETT). In a multivariate logistic regression model, coronary stenting during PCI and a ≥ 85% MPHR achieved were found to be inversely associated with clinical events. However, the DTS did not independently predict clinical events.

Conclusion

Although the statistical power of the study was limited by the small number of clinical events (particularly MI and death), the results of this study support the ACC/AHA guidelines that exercise treadmill testing should not be used routinely after PCI.     

Healthcare Service Utilization for Practicing Physicians: A Population-Based Study

Background

Physicians are considered to be the most informed consumers in the use of medical services since they have more information about diseases or medical technology. However, although plenty of researchers have suggested that different medical seeking behavior exists among physicians, very few empirical studies have been conducted to investigate differences in medical utilization between physicians and the general population.

Objective

We explored differences in the utilization of healthcare services between physicians and the general population using a population-based dataset.

Design

A cross-sectional study.

Participants

Data for this study were sourced from the Taiwan Longitudinal Health Insurance Database 2000. We included 1426 physicians and 1426 sex- and age-matched comparison subjects.

Methods

We used Wilcoxon-Mann-Whitney tests to explore differences in variables of healthcare resource utilization between physicians and comparison subjects. We further used Kruskal-Wallis tests to examine differences in variables of healthcare resource utilization between physician practice location and comparison subjects.

Results

We found that physicians had significantly fewer outpatient visits (13.2 vs. 15.7, p<0.001) and significantly lower outpatient costs (US$477 vs. US$680, p<0.001) than comparison subjects. Furthermore, physicians had lower total health service costs than comparison subjects (US$643 vs. US$1066, p<0.001). This indicates that the mean total health service costs in the year 2010 was 1.66-fold greater for comparison subjects than for physicians. We also found that there were significant differences in the mean number of outpatient services (p<0.001), outpatient costs (p = 0.001), inpatients costs (p = 0.018), and total costs (p = 0.001) among office-based physicians, hospital-based physicians, and comparison subjects. Specifically, Scheffe contrast tests showed that office-based physicians had significantly more outpatient visits (19.3 vs.10.7, p<0.001) and significantly higher outpatient costs (US$656 vs. US$402, p<0.001) than hospital-based physicians.

Conclusions

Physicians had less healthcare utilization than comparison subjects. Furthermore, hospital-based physicians had higher inpatient costs and less outpatient services and costs than office-based physicians.     

Tardive dyskinesia risk with first‐ and second‐generation antipsychotics in comparative randomized controlled trials: a meta‐analysis

Tardive dyskinesia (TD) risk with D2/serotonin receptor antagonists or D2 receptor partial agonists (second‐generation antipsychotics, SGAs) is considered significantly lower than with D2 antagonists (first‐generation antipsychotics, FGAs). As some reports questioned this notion, we meta‐analyzed randomized controlled studies (RCTs) to estimate the risk ratio (RR) and annualized rate ratio (RaR) of TD comparing SGAs vs. FGAs and SGAs vs. SGAs. Additionally, we calculated raw and annualized pooled TD rates for each antipsychotic. Data from 57 head‐to‐head RCTs, including 32 FGA and 86 SGA arms, were meta‐analyzed, yielding 32 FGA‐SGA pairs and 35 SGA‐SGA pairs. The annualized TD incidence across FGA arms was 6.5% (95% CI: 5.3‐7.8%) vs. 2.6% (95% CI: 2.0‐3.1%) across SGA arms. TD risk and annualized rates were lower with SGAs vs. FGAs (RR=0.47, 95% CI: 0.39‐0.57, p<0.0001, k=28; RaR=0.35, 95% CI: 0.28‐0.45, p<0.0001, number‐needed‐to‐treat, NNT=20). Meta‐regression showed no FGA dose effect on FGA‐SGA comparisons (Z=?1.03, p=0.30). FGA‐SGA TD RaRs differed by SGA comparator (Q=21.8, df=7, p=0.003), with a significant advantage of olanzapine and aripiprazole over other non‐clozapine SGAs in exploratory pairwise comparisons. SGA‐SGA comparisons confirmed the olanzapine advantage vs. non‐clozapine SGAs (RaR=0.66, 95% CI: 0.49‐0.88, p=0.006, k=17, NNT=100). This meta‐analysis confirms a clinically meaningfully lower TD risk with SGAs vs. FGAs, which is not driven by high dose FGA comparators, and documents significant differences with respect to this risk between individual SGAs.     

Pragmatic randomized controlled trial of long‐term psychoanalytic psychotherapy for treatment‐resistant depression: the Tavistock Adult Depression Study (TADS)

This pragmatic randomized controlled trial tested the effectiveness of long‐term psychoanalytic psychotherapy (LTPP) as an adjunct to treatment‐as‐usual according to UK national guidelines (TAU), compared to TAU alone, in patients with long‐standing major depression who had failed at least two different treatments and were considered to have treatment‐resistant depression. Patients (N=129) were recruited from primary care and randomly allocated to the two treatment conditions. They were assessed at 6‐monthly intervals during the 18 months of treatment and at 24, 30 and 42 months during follow‐up. The primary outcome measure was the 17‐item version of the Hamilton Depression Rating Scale (HDRS‐17), with complete remission defined as a HDRS‐17 score ≤8, and partial remission defined as a HDRS‐17 score ≤12. Secondary outcome measures included self‐reported depression as assessed by the Beck Depression Inventory ‐ II, social functioning as evaluated by the Global Assessment of Functioning, subjective wellbeing as rated by the Clinical Outcomes in Routine Evaluation ‐ Outcome Measure, and satisfaction with general activities as assessed by the Quality of Life Enjoyment and Satisfaction Questionnaire. Complete remission was infrequent in both groups at the end of treatment (9.4% in the LTPP group vs. 6.5% in the control group) as well as at 42‐month follow‐up (14.9% vs. 4.4%). Partial remission was not significantly more likely in the LTPP than in the control group at the end of treatment (32.1% vs. 23.9%, p=0.37), but significant differences emerged during follow‐up (24 months: 38.8% vs. 19.2%, p=0.03; 30 months: 34.7% vs. 12.2%, p=0.008; 42 months: 30.0% vs. 4.4%, p=0.001). Both observer‐based and self‐reported depression scores showed steeper declines in the LTPP group, alongside greater improvements on measures of social adjustment. These data suggest that LTPP can be useful in improving the long‐term outcome of treatment‐resistant depression. End‐of‐treatment evaluations or short follow‐ups may miss the emergence of delayed therapeutic benefit.     

Somatostatin: beneficial effects on remission in young adult patients with newly diagnosed diabetes mellitus type 1

To assess a possible influence of short-term administration of somatostatin on remission development in adult patients with newly diagnosed diabetes mellitus type 1, the somatostatin analog octreotide was given for two weeks after the establishment of the diagnosis at the daily dose of 150 microg subcutaneously in addition to the regular insulin and metabolic therapy. When compared to the control group, the remission was achieved earlier in the octreotide group (6+/-4 weeks vs. 11+/-12 weeks in the control group, p 0.05) and its duration was longer (99+/-49 weeks vs. 49+/-31 weeks in the control group, p 0.05). Moreover, remission also appeared in patients from the octreotide group with lower endogenous residual secretion of insulin (basal C peptide at the time of diagnosis in patients who later entered remission was 0.23+/-0.16 nmol/l vs. 0.34+/-.18 nmol/l in the control group, p<0.05). The increase of 24-h urine excretion of C-peptide after the therapy with octreotide was predictive for remission development. It can thus be concluded that octreotide administration in adults with newly diagnosed diabetes mellitus type 1 positively influences both the onset and duration of remission.     

口腔支持干预提高早产儿喂养效果

为了观察口腔支持干预在早产儿喂养中的应用效果,本研究选取2016年6月至2017年12月在长沙市口腔医院接受治疗的早产儿为研究对象,并根据其喂养方式分为对照组和观察组。对照组给予常规喂养,观察组在此基础上给予口腔支持干预。观察两组早产儿喂养效果、体重增长、住院时间的差异,比较两组早产儿营养指标和预后的差异。结果表明,观察组早产儿的开始经口喂养效率、摄入奶量比和完全经口喂养效率均高于对照组(t=11.060, 3.324, 5.934, p<0.001);观察组早产儿的出院时体重、体重增长率均高于对照组(t=8.844, 3.577, p<0.001),住院时间较对照组短(t=9.515, p<0.001);两组早产儿干预前的红细胞(red blood cell,RBC)、血清白蛋白(blood albumin, ALB)和前白蛋白(prealbumin, PA)水平无差别,干预后,观察组早产儿的RBC、ALB和PA水平高于对照组(t=1.951, 7.999, 11.724, p<0.05);观察组早产儿吐奶、吸吮吞咽无力和便秘发生率低于对照组(χ~2=4.891, p=0.027)。口腔支持干预在早产儿喂养中的应用效果较好,可明显提高其喂养效率,改善营养状况,具有良好的临床应用价值。     

Comparison of postsurgical and community acquired bacterial meningitis--analysis of 372 cases within a nationwide survey

The aim of this study was to assess if differences in etiology and risk factors among 372 cases of bacterial meningitis acquired after surgery (PM) or in community (CBM) have impact on outcome of infected patients. Among 372 cases of bacterial meningitis within last 17 years from 10 major Slovak hospitals, 171 were PM and 201 CBM. Etiology, risk factors such as underlying disease, cancer, diabetes alcoholism, surgery, VLBW, ENT infections, trauma, sepsis were recorded and mortality, survival with sequellae, therapy failure were compared in both groups. Significant differences in etiology and risk factors between both groups were reported. Those after neurosurgery had more frequently Coagulase negative staphylococci (p<0.001), Enterobacteriaceae (p=0.01) and Acinetobacter baumannii (p=0.0008) isolated from CSF and vice versa Streptococcus pneumoniae (p<0.001), Neisseria meningitis (p<0.001) and Haemophillus influenza (p=0.0009) were more commonly isolated from CSF in CBM. Neurosurgery (p<0.001), sepsis (p=0.006), VLBW neonates (p=0.00002) and cancer (p=0.0007) were more common in PM and alcohol abuse (p<0.001) as well as otitis/sinusitis (p<0.001) and Roma ethnic group (p=0.001) in CAM. Initial treatment success was significantly more frequently observed among CAM (p<0.001) but cure after modification was more common in PM (p=0.002). Therefore outcome in both groups was similar (14.6% vs. 12.4%, p=NS).     

Changes in the sleep–wake rhythm,sleep quality,mood, and quality of life of patients receiving treatment for lung cancer: A longitudinal study

Studies on the diurnal sleep–wake rhythm of patients with lung cancer have mostly examined patients cross-sectionally, whereas the effects of lung cancer treatment over time have rarely been considered. Through long-term longitudinal tracking of patients with lung cancer, this study examined changes in their sleep–wake rhythm, sleep quality, anxiety, depressive symptoms, fatigue and quality of life (QoL) at various treatment stages. In addition, factors affecting their QoL were explored. Hierarchical linear modeling was adopted to analyze a convenience sample of 82 patients with lung cancer. The changes in their sleep–wake rhythm, sleep, mood (anxiety, depressive symptoms and fatigue) and QoL were observed at five time points: prior to treatment and at weeks 6, 12, 24 and 48 after the start of the treatment. The effects of sex, age, cancer stage, treatment type, comorbidities and time were controlled to determine the predictors of patients’ QoL. The results showed that patients’ sleep–wake rhythms were poor before treatments. Compared with baseline, the sleep–wake rhythms of the patients significantly improved at week 48, and anxiety significantly improved at weeks 6, 12, 24 and 48. By contrast, their fatigue became exacerbated at weeks 8 and 48. Moreover, QoL improved significantly from week 6 until the end of the treatment period. QoL was negatively affected by poor sleep quality (β = ?0.69, p = 0.00) and depressive symptoms (β = ?2.59, p < 0.001) and positively affected by regular sleep–wake rhythms (β = 0.23, p = 0.001). Therefore, clinical health-care professionals should focus more attention to the fatigue levels of patients with lung cancer before, during and after treatment. Health-care professionals may also need to provide such patients with health education regarding sleep hygiene and with emotional support to assist them in maintaining regular sleep–wake rhythms in order to improve their QoL.     

The Effect of CYP19 and COMT Polymorphisms on Exercise‐Induced Fat Loss in Postmenopausal Women

Objective:To examine whether genetic polymorphisms in CYP19 [intron 4 (TTTA)_n; n = 7 to 13 and a 3‐base pair deletion, which is in strong linkage disequilibrium with the seven repeat] and COMT (Val^108/158Met) modified the change in BMI, total and percentage body fat, or subcutaneous and intra‐abdominal fat during a year‐long exercise intervention trial. These genes metabolize estrogens and androgens, which are important in body fat regulation. Research Methods and Procedures: A randomized intervention trial was used, with an intervention goal of 225 min/wk of moderate‐intensity exercise for one year. Participants (n = 173) were postmenopausal, 50 to 75 years old, sedentary, overweight or obese, and not taking hormone therapy at baseline. Results: Exercisers with two vs. no CYP19 11‐repeat alleles had a larger decrease in total fat (?3.1 kg vs. ?0.5 kg, respectively, p = 0.01) and percentage body fat (?2.4% vs. ?0.6%, respectively, p = 0.001). Exercisers with the COMT Met/Met vs. Val/Val genotype had a smaller decrease in percentage fat (?0.7% vs. ?1.9%, respectively, p = 0.05). Among exercisers, women with the COMT Val/Val genotype and at least one copy of the CYP19 11‐repeat allele vs. those with neither genotype/allele had a significantly larger decrease in BMI (?1.0 vs. +0.1 kg/m², respectively, p = 0.009), total fat (?2.9 vs. ?0.5 kg, respectively, p = 0.004), and percentage body fat (?2.6% vs. ?0.4%, respectively, p < 0.001). Discussion: Genetic polymorphisms in CYP19 and COMT may be important for body fat regulation and possibly modify the effect of exercise on fat loss in postmenopausal women.     

Robot-assisted therapy using the MOTOmed letto 2 for the integrated early rehabilitation of stroke patients admitted to the intensive care unit

In this study, we aimed to assess the effects of early robot-assisted rehabilitation using the MOTOmed letto 2 on neurological recovery, disease severity, the rate and severity of multiple organ dysfunction syndrome, and the rate of venous thromboembolism in acute stroke patients in the intensive care unit (ICU), including patients requiring mechanical ventilation. This case-control study included 66 patients (49 men and 17 women; median age, 59 years) with acute ischemic stroke and cerebral hemorrhage admitted to the ICU. Patients were divided into two comparable groups, the intervention group (n = 33) and the control group (n = 33), and monitored from admission to day 21. After admission, both groups received standard rehabilitation, and patients in the intervention group also received robot-assisted arm and leg therapy. The groups had similar median Glasgow coma scale (GCS), National Institutes of Health Stroke Scale (NIHSS), APACHE II, and multiple organ dysfunction scale (MODS) scores on admission. There were no significant differences in neurological and medical outcomes on day 21 between the intervention and control groups (median GCS: 15 vs. 15, p = 0.32; median NIHSS 11 vs. 15, p > 0.05; median APACHE II: 6 vs. 9, p > 0.05; median MODS: 0 vs. 1, p > 0.05). The prevalence of multiple organ dysfunction syndrome and deep venous thrombosis (DVT) on day 21 was also similar in the intervention and control groups (60% vs. 67%, p > 0.05, and 58% vs. 45%, p > 0.05, respectively). However, the prevalence of severe multiple organ dysfunction syndrome, the incidence of pulmonary embolism, and the mortality rate were lower in the intervention group compared with the control group (14% vs. 41%, p < 0.05; 12% vs. 33%; p < 0.05; 12% vs. 39%, p < 0.05, respectively). Our results indicate that early robot-assisted therapy in patients with severe stroke admitted to the ICU reduces the rate of pulmonary embolism, the incidence of severe multiple organ dysfunction, and mortality on day 21, but does not influence neurological outcomes or the rate of deep vein thrombosis.     

A primary care weight management intervention for low-income African-American women

Objective: To determine whether a tailored weight management program, addressing the needs of obese, low‐income African‐American women, would produce greater weight loss than standard medical care. Research Methods and Procedures: A randomized, controlled trial was conducted between 1999 and 2003 with 144 overweight or obese women (predominantly African‐American) enrolled at two primary care clinics. Four physicians at each clinic were randomly assigned to provide either tailored weight management interventions or standard care. The tailored condition consisted of six monthly outpatient visits lasting ～15 minutes each, which included personalized materials and messages. The main outcome was body weight change. Results: The intervention group lost more weight than the standard care group (p = 0.03). The tailored group lost a mean (standard deviation) of 2.0 (3.2) kg by Month 6. The standard care group gained 0.2 (2.9) kg. More participants in the tailored group lost weight (79% vs. 47%; p = 0.04). Discussion: Obese, low‐income, African‐American women provided with 90 minutes of physician‐delivered, tailored weight management instruction over 6 months achieved greater weight loss than those receiving standard medical care. The primary care physician can be effective in delivering weight loss interventions, and the primary care clinic may be a useful setting to implement weight management interventions.     

Effect of oral application of a probiotic<Emphasis Type="Italic">E. coli</Emphasis> strain on the intestinal microflora of children of allergic mothers during the first year of life

Influence of intestinal colonization by a probiotic E. coli strain on the incidence of bacterial pathogens in stool and allergic symptoms during the 1st year of life was monitored in 3 groups: colonized children of allergic mothers (AC; n = 52), noncolonized children of allergic mothers (AN; n = 50), children of nonallergic mothers (NC; n = 42). Colinfant vaccine was administered within 2 d after birth, 3 x a week over a period of 4 weeks. Stool samples were examined after 2 d and at the age of 3, 6 and 12 months. At 3 months E. coli was present in 90 %, at 12 months in 73 % of AC. Pathogens were significantly less frequent on day 3 and at 3 months in AC vs. AN (15 vs. 61 %, p < 0.001; 15 vs. 38 %, p < 0.01) and vs. NC (15 vs. 63 %, p < 0.001; 15 vs. 53 %, p < 0.001). AC exhibited lower incidence of Staphylococcus epidermidis than AN on day 3 (6 vs. 31 %, p < 0.001) and of Klebsiella strains on day 3 and at 3 months (4 vs. 20 %, p < 0.05; 5 vs. 24 %, p < 0.01). AC showed a lower incidence of Pseudomonas aeruginosa than NC on day 3 (6 vs. 31 %, p < 0.01) and Klebsiella spp. on day 3 and at 3 months (4 vs. 22 %, p < 0.05; 5 vs. 45 %, p < 0.001). No significant differences were recorded after 6 and 12 months. The incidence of allergies was 3 % in AC, 26 % in AN (p < 0.01), and 10 % in NC.     

The national utilization of immediate and early delayed breast reconstruction and the effect of sociodemographic factors

The purpose of this study was to identify important sociodemographic factors affecting the utilization of immediate and early delayed postmastectomy breast reconstruction in the United States. Using the Surveillance, Epidemiology, and End Results (SEER) program, all cases of mastectomy-treated breast cancer that were reported to a SEER registry in 1998 were identified. Data were limited to reconstructions within the first 4 months postmastectomy, and logistic regression was used to analyze the effects of sociodemographic variables on reconstruction rates. Of the 10,406 mastectomy-treated breast cancer patients, 1607 (15 percent) underwent reconstruction within the first 4 months postmastectomy. Compared with women 45 to 54 years old, those 35 to 44 years old were significantly more likely to have breast reconstruction (OR = 1.52, p < 0.001), but women 55 to 64, 65 to 74, and 75 years and older were significantly less likely to have reconstruction (OR = 0.42, p < 0.001; OR = 0.16, p < 0.001; OR = 0.04, p < 0.001, respectively). Compared with Caucasian women, African American, Hispanic, and Asian women were significantly less likely to have reconstruction (OR = 0.48, p < 0.001; OR = 0.45, p < 0.001; OR = 0.29, p < 0.001, respectively). In addition, a four-fold difference in reconstruction rates existed in high-use versus low-use regions. With regard to the type of reconstruction, patients younger than 35 and 65 to 74 years old were significantly less likely to receive autogenous tissue reconstruction compared with women 45 to 54 years old (OR = 0.47, p = 0.047; OR p = 0.61, p = 0.031, respectively). However, African Americans were significantly more likely to receive autogenous tissue reconstructions compared with Caucasians (OR = 2.03, p = 0.021). According to these data, the utilization of immediate and early delayed breast reconstruction in the United States is low and is significantly influenced by patients' age, race, and geographic location. Further research is needed to evaluate the impact of provider bias, patient preference, and barriers to care on the utilization of breast reconstruction in the United States.     

A physician-centered intervention to shorten hospital stay: a pilot study

BACKGROUND: Studies of length of stay (LOS) in hospital usually focus on physician-independent factors. In this study, the authors identified physician-dependent factors and tested an intervention aimed at them to determine its effect on LOS. METHODS: A prospective comparison of LOS on 2 general medical wards in a tertiary care teaching hospital before and after the intervention. The pre-intervention (control) period and the intervention period were each 4 weeks. The intervention consisted of a checklist for planning management and discharge. RESULTS: Overall, the mean LOS was shorter during the intervention period than during the control period, but the difference was not statistically significant (12.0 and 14.4 days respectively, p = 0.13). The difference was significant on ward A (11.0 v. 14.7 days respectively, p = 0.02) but not on ward B (13.0 and 14.0 days respectively, p = 0.90). INTERPRETATION: An intervention at the level of the admitting physician may help to shorten LOS on a general medical ward.     

Cost analysis of early discharge after hip fracture.

OBJECTIVE--To ascertain the economic impact of an early discharge scheme for hip fracture patients. DESIGN--Population based study comparing costs of care for patients who had "hospital at home" as an option for rehabilitation and those who had no early discharge service available in their area of residence. SETTING--District hospital orthopaedic and rehabilitation wards and community hospital at home scheme. PATIENTS--1104 consecutively admitted patients with fractured neck of femur. 24 patients from outside the district were excluded. MAIN OUTCOME MEASURES--Cost per patient episode and number of bed days spent in hospital. RESULTS--Patients with the hospital at home option spent significantly less time as inpatients (mean of 32.5 v 41.7 days; p < 0.001). Those patients who were discharged early spent a mean of 11.5 days under hospital at home care. The total direct cost to the health service was significantly less for those patients with access to early discharge than those with no early discharge option (4884 pounds v 5606 pounds; p = 0.048). CONCLUSIONS--About 40% of patients with fractured neck of femur are suitable for early discharge to a scheme such as hospital at home. The availability of such a scheme leads to lower direct costs of rehabilitative care despite higher readmission costs. These savings accrue largely from shorter stays in orthopaedic and geriatric wards.     

Effectiveness and costs associated with a lay counselor–delivered,brief problem-solving mental health intervention for adolescents in urban,low-income schools in India: 12-month outcomes of a randomized controlled trial

BackgroundPsychosocial interventions for adolescent mental health problems are effective, but evidence on their longer-term outcomes is scarce, especially in low-resource settings. We report on the 12-month sustained effectiveness and costs of scaling up a lay counselor–delivered, transdiagnostic problem-solving intervention for common adolescent mental health problems in low-income schools in New Delhi, India.Methods and findingsParticipants in the original trial were 250 school-going adolescents (mean [M] age = 15.61 years, standard deviation [SD] = 1.68), including 174 (69.6%) who identified as male. Participants were recruited from 6 government schools over a period of 4 months (August 20 to December 14, 2018) and were selected on the basis of elevated mental health symptoms and distress/functional impairment. A 2-arm, randomized controlled trial design was used to examine the effectiveness of a lay counselor–delivered, problem-solving intervention (4 to 5 sessions over 3 weeks) with supporting printed booklets (intervention arm) in comparison with problem solving delivered via printed booklets alone (control arm), at the original endpoints of 6 and 12 weeks. The protocol was modified, as per the recommendation of the Trial Steering Committee, to include a post hoc extension of the follow-up period to 12 months. Primary outcomes were adolescent-reported psychosocial problems (Youth Top Problems [YTP]) and mental health symptoms (Strengths and Difficulties Questionnaire [SDQ] Total Difficulties scale). Other self-reported outcomes included SDQ subscales, perceived stress, well-being, and remission. The sustained effects of the intervention were estimated at the 12-month endpoint and over 12 months (the latter assumed a constant effect across 3 follow-up points) using a linear mixed model for repeated measures and involving complete case analysis. Sensitivity analyses examined the effect of missing data using multiple imputations. Costs were estimated for delivering the intervention during the trial and from modeling a scale-up scenario, using a retrospective ingredients approach. Out of the 250 original trial participants, 176 (70.4%) adolescents participated in the 12-month follow-up assessment. One adverse event was identified during follow-up and deemed unrelated to the intervention. Evidence was found for intervention effects on both SDQ Total Difficulties and YTP at 12 months (YTP: adjusted mean difference [AMD] = −0.75, 95% confidence interval [CI] = −1.47, −0.03, p = 0.04; SDQ Total Difficulties: AMD = −1.73, 95% CI = −3.47, 0.02, p = 0.05), with stronger effects over 12 months (YTP: AMD = −0.98, 95% CI = −1.51, −0.45, p < 0.001; SDQ Total Difficulties: AMD = −1.23, 95% CI = −2.37, −0.09; p = 0.03). There was also evidence for intervention effects on internalizing symptoms, impairment, perceived stress, and well-being over 12 months. The intervention effect was stable for most outcomes on sensitivity analyses adjusting for missing data; however, for SDQ Total Difficulties and impairment, the effect was slightly attenuated. The per-student cost of delivering the intervention during the trial was $3 United States dollars (USD; or $158 USD per case) and for scaling up the intervention in the modeled scenario was $4 USD (or $23 USD per case). The scaling up cost accounted for 0.4% of the per-student school budget in New Delhi. The main limitations of the study’s methodology were the lack of sample size calculations powered for 12-month follow-up and the absence of cost-effectiveness analyses using the primary outcomes.ConclusionsIn this study, we observed that a lay counselor–delivered, brief transdiagnostic problem-solving intervention had sustained effects on psychosocial problems and mental health symptoms over the 12-month follow-up period. Scaling up this resource-efficient intervention is an affordable policy goal for improving adolescents’ access to mental health care in low-resource settings. The findings need to be interpreted with caution, as this study was a post hoc extension, and thus, the sample size calculations did not take into account the relatively high attrition rate observed during the long-term follow-up.Trial registrationClinicalTrials.gov {"type":"clinical-trial","attrs":{"text":"NCT03630471","term_id":"NCT03630471"}}NCT03630471.
