Weight loss on the web: A pilot study comparing a structured behavioral intervention to a commercial program

Objective: Internet weight loss programs have become widely available as alternatives to standard treatment, but few data are available on their efficacy. This study aimed to investigate the effectiveness of a structured behavioral weight loss website (VTrim) vs. a commercial weight loss website ( eDiets.com ). Research Methods and Procedures: A randomized, controlled trial was conducted from February 2003 to March 2005, in 124 overweight and obese subjects ages 18 years and older with a BMI of 25 to 39.9 kg/m² (mean age, 47 ± 9 years; BMI, 32 ± 3 kg/m²; 20% men). Analyses were performed for the 88 subjects who had complete follow‐up data. Participants were randomly assigned to 12‐month VTrim (n = 62) or eDiets.com (n = 62) intervention. VTrim participants had access to a therapist‐led structured behavioral weight loss program delivered on‐line. eDiets.com subjects had access to a self‐help commercial on‐line weight loss program. Body weight, social support, and use of website components were measured at 0, 6, and 12 months. Results: Repeated‐measures analyses showed that the VTrim group lost significantly more weight than the eDiets.com group at 6 months (8.3 ± 7.9 kg vs. 4.1 ± 6.2 kg; p = 0.004) and maintained a greater loss at 12 months (7.8 ± 7.5 kg vs. 3.4 ± 5.8 kg; p = 0.002). More participants in the VTrim group maintained a 5% weight loss goal (65% vs. 37.5%; p = 0.01) at 12 months. Discussion: An on‐line, therapist‐led structured behavioral weight loss website produced greater weight loss than a self‐help commercial website. Because commercial sites have great potential public health impact, future research should investigate the feasibility of incorporating a more structured behavioral program into a commercial application.     

Strengthening individual and family resilience against leprosy-related discrimination: A pilot intervention study

BackgroundLeprosy and leprosy-related stigma can have a major impact on psychosocial wellbeing of persons affected and their family members. Resilience is a process that incorporates many of the core skills and abilities which may enable people to address stigma and discrimination. The current study aimed to develop and pilot an intervention to strengthen individual and family resilience against leprosy-related discrimination.MethodologyWe used a quasi-experimental, before-after study design with a mixed methods approach. The 10-week family-based intervention was designed to strengthen the resilience of individuals and families by enhancing their protective abilities and capacity to overcome adversity. The study was conducted in two sites, urban areas in Telangana state, and in rural areas in Odisha state, India. Persons affected and their family members were included using purposive sampling. Two questionnaires were used pre-and post-intervention: the Connor-Davidson Resilience Scale (CD-RISC, maximum score 100, with high scores reflecting greater resilience) and the WHOQOL-BREF (maximum score of 130, with higher scores reflecting higher quality of life). In addition, semi-structured interviews were conducted post-intervention. Data were collected at baseline, a few weeks after completion of the intervention, and in the Odisha cohort again at six months after completion. Paired t-tests measured differences pre- and post- intervention. Qualitative data were thematically analysed.FindingsEighty participants across 20 families were included in the study (23 persons affected and 57 family members). We found a significant increase in CD-RISC scores for persons affected and family members from Odisha state (baseline 46.5, first follow-up 77.0, second follow-up 70.0), this improvement was maintained at six-month follow-up. There was no increase in CD-RISC scores post-intervention among participants from Telangana state. WHOQOL-BREF scores were significantly higher at follow-up for persons affected in both states, and for family members in Odisha state. No families dropped out of the study. In the qualitative feedback, all participants described drawing benefit from the programme. Participants especially appreciated the social dimensions of the intervention.ConclusionThis pilot study showed that the 10-week family-based intervention to strengthen resilience among persons affected by leprosy and their family members was feasible, and has the potential to improve resilience and quality of life. A large-scale efficacy trial is necessary to determine the effectiveness and long-term sustainability of the intervention.     

Evaluation of a multicomponent intervention to shorten thrombolytic door-to-needle time in stroke patients in China (MISSION): A cluster-randomized controlled trial

BackgroundRapid intravenous thrombolysis (IVT) for acute ischemic stroke (AIS) is crucial for improving outcomes. However, few randomized trials of interventions aimed at reducing in-hospital delay have been carried out in China. We aimed to evaluate the effect of a multicomponent intervention on thrombolytic door-to-needle time (DNT) of AIS patients via video teleconference based on the Behavior Change Wheel (BCW) method.Methods and findingsThis cluster-randomized trial, conducted between January 1, 2019 and December 31, 2019, randomly allocated 22 hospitals equally to PEITEM (Persuasion Environment reconstruction Incentivization Training Education Modeling) intervention or routine care plus stroke registry and subsequently enrolled 1,634 AIS patients receiving IVT within 4.5 hours upon stroke onset from participant hospitals. The PEITEM group received a 1-year PEITEM 6-component intervention based on the behavioral theory monthly via video teleconference. The primary outcome was the proportion of patients with a DNT of 60 minutes or less. A total of 987 patients participated in the PEITEM group (mean age, 69 years; female, 411 [41.6%]) and 647 patients in the control group (mean age, 70 years; female, 238 [36.8%]). Of all participants, the proportion of DNT ≤60 minutes in the PEITEM group was higher than in the control group (82.0% versus 73.3%; adjusted odds ratio, 1.77; 95% confidence interval (CI), 1.17 to 2.70; ICC, 0.04; P = 0.007). Among secondary outcomes, the average DNT was 43 minutes in the PEITEM group and 50 minutes in the control group (adjusted mean difference: −8.83; 95% CI, −14.03 to −3.64; ICC, 0.12; P = 0.001). Favorable functional outcome (score of 0 to 1 on the modified Rankin scale (mRS)) was achieved in 55.6% patients of the PEITEM group and 50.4% of the control group (adjusted odds ratio, 1.38; 95% CI, 1.00 to 1.90; ICC, 0.01; P = 0.049). Main study limitations include non-blinding of clinicians, and that specific interventions component responsible for the observed changes could not be determined.ConclusionsThe teleconference-delivered PEITEM intervention resulted in a moderate but clinically relevant shorter DNT and better functional outcome in AIS patients receiving IVT.Trial registrationClinicaltrials.gov {"type":"clinical-trial","attrs":{"text":"NCT03317639","term_id":"NCT03317639"}}NCT03317639.

Predictors for length of hospital stay in patients with community-acquired Pneumonia: Results from a Swiss Multicenter study

ABSTRACT: BACKGROUND: Length of hospital stay (LOS) in patients with community-acquired pneumonia (CAP) is variable and directly related to medical costs. Accurate estimation of LOS on admission and during follow-up may result in earlier and more efficient discharge strategies. METHODS: This is a prospective multicenter study including patients in emergency departments of 6 tertiary care hospitals in Switzerland between October 2006 and March 2008. Medical history, clinical data at presentation and health care insurance class were collected. We calculated univariate and multivariate cox regression models to assess the association of different characteristics with LOS. In a split sample analysis, we created two LOS prediction rules, first including only admission data, and second including also additional inpatient information. RESULTS: The mean LOS in the 875 included CAP patients was 9.8 days (95%CI 9.3-10.4). Older age, respiratory rate >20pm, nursing home residence, chronic pulmonary disease, diabetes, multilobar CAP and the pneumonia severity index class were independently associated with longer LOS in the admission prediction model. When also considering follow-up information, low albumin levels, ICU transfer and development of CAP-associated complications were additional independent risk factors for prolonged LOS. Both weighted clinical prediction rules based on these factors showed a high separation of patients in Kaplan Meier Curves (p logrank <0.001 and <0.001) and a good calibration when comparing predicted and observed results. CONCLUSIONS: Within this study we identified different baseline and follow-up characteristics to be strong and independent predictors for LOS. If validated in future studies, these factors may help to optimize discharge strategies and thus shorten LOS in CAP patients.     

Mate selection criteria: A pilot study

Open-ended questions were used to investigate mate selection criteria among male and female medical students (n = 40). Striking sex differences emerged in this sample's preferences concerning spouses' relative earning power and occupational status, partners' physical attractiveness, and the marital division of labor. The results supported the hypotheses: Increasing socioeconomic status (SES) of women does not eliminate and may not even reduce traditional sex differences in mate selection criteria and marital goals. Increasing the SES of women tends to increase their socioeconomic standards for mates, thereby reducing their pool of acceptable partners; increasing men's SES tends to enlarge their pool of available acceptable partners. Based on these interviews and pertinent literature, closed-ended questions were developed and administered to female (n = 212) and male (n = 170) undergraduates. Highly significant sex differences emerged in this sample; these sex differences mirrored those found among the medical students. The methodological implications of these results are discussed.     

A novel noninvasive index for nonalcoholic steatohepatitis: a pilot study

Abstract

Objective: The potential development of a noninvasive marker predicting nonalcoholic steatohepatitis (NASH).

Methods: Thirty patients with biopsy-proven nonalcoholic fatty liver disease were evaluated by numerous anthropometric, clinical and biochemical parameters.

Results: Serum glutamic oxaloacetic transaminase (SGOT; p?=?0.027), log (erythrocyte sedimentation rate) (ESR; p?=?0.034) and homocysteine (p?=?0.041) were associated with NASH independently from gender, age and body mass index. When combined, the regression model provided R²?=?0.563 (p?=?0.001) and area under the ROC curve?=?0.873?±?0.066 (p?<?0.001).

Conclusion: This noninvasive marker, named HSENSI (acronym of homocysteine, SGOT, ESR, Nonalcoholic Steatohepatitis Index), consists of three low cost, easily measurable parameters and may accurately predict NASH.     

Reduction in hospital readmission stay of elderly patients by a community based hospital discharge scheme: a randomised controlled trial.

STUDY OBJECTIVE--To compare a community support scheme using care attendants with standard aftercare for their effects on independence and morale of elderly patients discharged from hospital and on their use of health and social services. DESIGN--Randomised controlled study of cohort of patients over 75 discharged to their own homes. SETTING--District general hospital and community. PATIENTS--Total of 903 patients (mean age 82, 25% over 85). INTERVENTIONS--Total of 464 patients received support from care attendants on first day at home and for up to 12 hours a week for two weeks. Support comprised practical care, help with rehabilitation, and organising social help. The remaining 439 patients received standard aftercare. END POINT--Difference between two groups of 7% in hospital readmission rates or one point on activities of daily living scale (power 80%, significance level 5%). MEASUREMENTS AND MAIN RESULTS--Three months after the initial discharge 763 patients were interviewed (84%). There were no significant differences between the two groups in physical independence (activities of daily living scale), in measures of morale (Philadelphia scale), or in death rates. Hospital readmission rates within 18 months of discharge, however, were significantly higher in the control group and they spent more days in hospital (mean; control group 30.6 days, support group 17.1 days; p = 0.014). Of the patients living alone who were followed up for 18 months 21 (15%) receiving standard aftercare were readmitted more than twice compared with 6 (5%) supported by care attendants (p less than 0.01). CONCLUSIONS--If the findings are confirmed, and the policy extended to all patients over the age of 75 living alone, an average health district might expect either to save about 23 hospital beds at a net annual saving of about pounds 220,000 in the short term or to increase available beds by this number.     

Use of hospital beds: a cohort study of admissions to a provincial teaching hospital.

An instrument was developed to study the use of hospital beds and discharge arrangements of a cohort of 847 admissions to the John Radcliffe Hospital, Oxford, for a three week period during February-March 1986. For only 38% of bed days were patients considered to have medical, nursing, or life support reasons for requiring a provincial teaching hospital bed. The requirements for a bed in the hospital decreased with the patient''s age and length of stay in hospital. For only a tenth of patients was the general practitioner concerned in discussions with hospital staff about the patient''s discharge and less than one third of patients had been given more than 24 hours'' notice of discharge. Several features might increase the proportion of bed days that are occupied by patients with positive reasons for being in hospital. Among these are an increased frequency of ward rounds by consultants, or delegating discharge decisions by consultants to other staff; providing diagnostic related protocols for planning the length of stay in hospital; planned discharges; and providing liaison nurses to help with communication with primary care staff.     

Cefoxitin: a hospital study.

Cefoxitin is a new cephamycin antibiotic that has recently become available for clinical trial. We report here the results of an uncontrolled trial of cefoxitin treatment in 31 hospital patients with various acute infections, 20 of whom were cured. Serum, urine, and bile concentrations of cefoxitin greatly exceeded the minimum inhibitory concentration (MIC) required for clinically important Gram-negative organisms. We conclude that cefoxitin will have a place in the management of serious infections, particularly in the abdominal cavity and renal tracts.     

Cryopreservation of houbara semen: A pilot study

The potential of producing viable houbara bustard Chlamydotis undulata undulata progeny with cryopreserved semen was investigated during the 1998 breeding season. Houbara semen was diluted and rapidly frozen into pellet form in LN₂ using dimethylacetamide (DMA) as a cryoprotectant. Thawed semen exhibited 24.86± 10.61% recovery of fresh sperm motility levels and 36.44±16.17% of fresh viability counts. Two second‐year females were inseminated on two and three occasions, respectively, with thawed semen. One female laid four eggs between two clutches and the second female laid two eggs in a single clutch. All eggs were fertile; two developed to 18–21days but failed to pip; one chick died at pip and three chicks hatched. This is the first documented occasion that houbara bustard chicks were conceived with cryopreserved semen and it demonstrates the feasibility of using a rapid, simple, and relatively inexpensive methodology to achieve this result.

Cystic fibrosis newborn screening: a pilot study to maximize carrier screening

Newborn screening for cystic fibrosis (CF) is expanding because early diagnosis has been shown to result in improved nutrition and growth. Most newborns identified by a mutation panel have a single detected mutation and require sweat testing to exclude an additional undetected mutation. The resulting identification of CF carrier newborns, although not the primary purpose of screening, has three potential benefits, (1) the detection of trait-trait couples, (2) presymptomatic testing of these couples' previously born children who may have undetected CF, and (3) a carrier parent alerting his/her extended family members to the chance of also being a CF carrier. Reaping each benefit requires genetic counseling of parents and their accepting carrier testing. The purpose of this study was to utilize the sweat testing visit to educate parents about the value of carrier testing for themselves and their blood relatives. We compared special care (genetic counseling after explaining the sweat test result and offering of parental DNA testing, all on the sweat test visit) versus standard care (sweat test result reported by phone to the parents the next day by the newborn's physician, ideally with the recommendation to arrange genetic counseling and parental carrier testing). In the first year of New York State CF screening, 64 newborns with one detected mutation were reported in the nine-county region that includes Rochester. Of these, parents of 39 agreed to participate in the study and to be randomized to special or standard care. Sixty-one parents completed both the initial and 1-year follow-up questionnaires (30 couples and one mother). Of the 61 parents, 23 had carrier testing after the birth of the baby. The frequency of such parental testing was significantly higher in the special care group (17/34 or 50%) than in the standard care group (6/27 or 22%) (p < 0.05). This is the first evidence from a randomized trial that genetic counseling and offering carrier testing to parents on the sweat test visit increases identification of carrier parents. Such identification detects trait-trait parents and facilitates carrier testing among relatives.
