Relationship between Obstructive Sleep Apnea Severity and Sleep,Depression and Anxiety Symptoms in Newly-Diagnosed Patients

Obstructive sleep apnea (OSA) occurs in at least 10% of the population, and leads to higher morbidity and mortality; however, relationships between OSA severity and sleep or psychological symptoms are unclear. Existing studies include samples with wide-ranging comorbidities, so we assessed relationships between severity of OSA and common sleep and psychological disturbances in recently diagnosed OSA patients with minimal co-morbidities. We studied 49 newly diagnosed, untreated OSA patients without major co-morbidities such as mental illness, cardiovascular disease, or stroke; subjects were not using psychoactive medications or tobacco (mean ± std age: 46.8±9.1 years; apnea/hyponea index [AHI]: 32.1±20.5 events/hour; female/male: 12/37; weight <125 kg). We evaluated relationships between the AHI and daytime sleepiness (Epworth Sleepiness Scale; ESS), sleep quality (Pittsburg Sleep Quality Index; PSQI), depressive symptoms (Beck Depression Inventory-II; BDI), and anxiety symptoms (Beck Anxiety Inventory; BAI), as well as sex and body mass index (BMI). AHI was similar in females and males. Mean levels of all symptoms were above normal thresholds, but AHI was not correlated with age, ESS, PSQI, BDI, or BAI; only BMI was correlated with OSA severity. No differences in mean AHI appeared when subjects were grouped by normal versus elevated values of ESS, PSQI, BDI, or BAI. Consistent with other studies, a strong link between OSA severity and psychological symptoms did not appear in these newly diagnosed patients, suggesting that mechanisms additional to the number and frequency of hypoxic events and arousals occurring with apneas contribute to adverse health effects in OSA. OSA patients presenting with mild or moderate severity, and no major co-morbidities will not necessarily have low levels of sleep or psychological disturbances.     

Influence of personality disorder on the treatment of panic disorder--comparison study

Most clinicians tend to believe that the occurrence of the anxiety disorder in comorbidity with a personality disorder often leads to longer treatment, worsens the prognosis, and thus increasing treatment costs. The study is designed to compare the short-term effectiveness of combination of cognitive behavioral therapy and pharmacotherapy in patient suffering with panic disorder with and without personality disorder. METHOD: We compare the efficacy of 6th week therapeutic program and 6th week follow up in patients suffering with panic disorder and/or agoraphobia and comorbid personality disorder (29 patients) and panic disorder and/or agoraphobia without comorbid personality disorder (31 patients). Diagnosis was done according to the ICD-10 research diagnostic criteria confirmed with MINI and support with psychological methods: IPDE, MCMI-III and TCI. Patients were treated with CBT and psychopharmacs. They were regularly assessed in week 0, 2, 4, 6 and 12 by an independent reviewer on the CGI (Clinical Global Improvement) for severity and change, PDSS (Panic Disorder Severity Scale), HAMA (Hamilton Anxiety Rating Scale), SDS (Sheehan Disability Scale), HDRS (Hamilton Depression Rating Scale), and in self-assessments BAI (Beck Anxiety Inventory) and BDI (Beck Depression Inventory). RESULTS: A combination of CBT and pharmacotherapy proved to be the effective treatment of patients suffering with panic disorder and/or agoraphobia with or without comorbid personality disorder. The 12th week treatment efficacy in the patients with panic disorder without personality disorder had been showed significantly better compared with the group with panic disorder comorbid with personality disorder in CGI and specific inventory for panic disorder--PDSS. Also the scores in depression inventories HDRS and BDI showed significantly higher decrease during the treatment comparing with group without personality disorder. But the treatment effect between groups did not differ in objective anxiety scale HAMA, and subjective anxiety scale BAI.     

The Efficacy of Neurofeedback in Patients with Major Depressive Disorder: An Open Labeled Prospective Study

The purpose of this study was to evaluate the effect of neurofeedback on depressive symptoms and electrophysiological disturbances in patients with major depressive disorder. We recruited participants suffering from depression to evaluate efficacy of left prefrontal beta with alpha/theta training. An 8-week, prospective, open-label study was undertaken. Twenty participants were recruited. The treatment protocol was twice or three times a week training of beta at F3 with alpha/theta at Pz for 8 weeks. When every visit, patients were received beta training for 30 min, and then alpha/theta training for 30 min. Baseline, 4 and 8 week scores of; the Hamilton rating scale for Depression (HAM-D), the Hamilton rating scale for Anxiety (HAM-A), the Beck Depression Inventory (BDI)-II, the Beck Anxiety Inventory (BAI), Clinical global impression-severity (CGI-S), and pre- and post-treatment resting state EEGs were compared. Interhemispheric alpha power asymmetry (A score) was computed for homologous sites F3–F4. Pre- and post-training clinical assessments revealed significant improvements in HAM–D, HAM-A, BDI, and CGI-S scores. Cumulative response rates by HAM-D were 35.0 and 75.0 % at 4 and 8 weeks, respectively, corresponding cumulative remission rates by HAM-D were 15.0 and 55.0 %, respectively. No significant differences were found between pre- and post-treatment A score. Neurofeedback treatment could improve depressive symptoms significantly. In addition, anxiety symptoms and clinical illness severity decreased significantly after neurofeedback treatment. Despite its several limitations, such as, small sample size and lack of a control group, this study suggested neurofeedback has significant effects in patients with major depressive disorder.     

Is it true that essential tremor affects sleep? A comparison between young essential tremor patients and normal controls

Essential tremor (ET) is the most common movement disorder and cause of functional disability. ET is known as a monosymptomatic, pure motor system disease. This interpretation of ET has been questioned in the last decade. Non-motor symptoms have added to the definition of the disease. In autopsy studies, it has been reported that Lewy bodies are common in the locus coeruleus, which is known to have an active role in sleep. Previous research about sleep in ET has studied older patients. Sleep disturbances are common in older adults. Our study focused on younger patients who had the disease for a shorter period of time. 40 patients (24.9 ± 7.0 years old) and 28 controls were recruited for the study. Sleep quality was evaluated with the Pittsburg Sleep Quality Index (PSQI). Excessive daytime sleepiness (EDS) was evaluated with the Epworth Sleepiness Scale (ESS). For assessing the possible impact of depression and anxiety on sleep we used the Beck Depression Inventory (BDI), and the Beck Anxiety Scale (BAS). We ruled out other possible causes of tremor. Tremor was evaluated using the Fahn Tolosa Marin Tremor Rating Scale (FTM-TRS). We concluded that although ET patients had bad sleep quality, this might be associated with increased anxiety levels. Mean ESS scores were higher in the patient group, but this was not statistically significant.

Association of Mood Disorders with Serum Zinc Concentrations in Adolescent Female Students

Among various factors influencing mood disorders, the impact of micronutrient deficiencies has attracted a great attention. Zinc deficiency is considered to play a crucial role in the onset and progression of mood disorders in different stages of life. The main objective of this study was to assess the correlation between serum zinc levels and mood disorders in high school female students. This cross-sectional study was conducted on a random sample of 100 representative high school female students. The participants completed 24-h food recall questionnaires to assess the daily zinc intakes. Serum zinc status was assessed using flame atomic absorption spectrometry, and zinc deficiency was defined accordingly. Mood disorders were estimated by calculating the sum of two test scores including Beck’s depression inventory (BDI) and hospital anxiety depression scale (HADS) tests. General linear model (GLM) and Pearson’s regression test were applied to show the correlation of serum zinc levels and mood disorder scores and the correlation between zinc serum levels and BDI scores, respectively. Dietary zinc intake was higher in subjects with normal zinc concentrations than that of zinc-deficient group (p = 0.001). Serum zinc levels were inversely correlated with BDI and HADS scores (p < 0.05). Each 10 μg/dL increment in serum zinc levels led to 0.3 and 0.01 decrease in depression and anxiety scores, respectively (p < 0.05). Serum zinc levels were inversely correlated with mood disorders including depression and anxiety in adolescent female students. Increasing serum levels of zinc in female students could improve their mood disorders.

Prevalence of Undiagnosed Depression among Persons with Hypertension and Associated Risk Factors: A Cross-Sectional Study in Urban Nepal

BackgroundDespite an increasing number of studies exploring prevalence of depression among hypertensive patients in high income countries, limited data is available from low and middle income countries, particularly Nepal. Our aim was to investigate the prevalence of undiagnosed (sub clinical) depression and associated risk factors among hypertensive patients attending a tertiary health care clinic in Nepal.MethodsThe study was based on a cross-sectional study design, with 321 hypertensive patients attending the Out-Patient Department of a central hospital in Nepal. Blood measure was recorded via a mercury column sphygmomanometer. Depression levels were assessed using the Beck Depression Inventory-Ia (BDI) scale. Demographics and risk factors were assessed.ResultThe proportion of participants with undiagnosed depression was 15%. Multivariable analyses demonstrated an increase in BDI scores with increased aging. Approximately a 1 point increase in the BDI score was observed for each additional decade of aging in hypertensive patients. Additional factors associated with increased risk of depression included being female (4.28 point BDI score increase), smoking (5.61 point BDI score increase), being hypertensive with no hypertensive medication (4.46 point BDI score increase) and being illiterate (4.46 point BDI score increase).ConclusionsAmong persons with hypertension in outpatient settings in Nepal, demographic (age, sex, education), behavioural (smoking,) and adherence factors (anti-hypertensive medication) were associated with undiagnosed depression. Screening programs in Nepal may assist early intervention in hypertensive patients with sub clinical depression.

Genomewide linkage analysis of quantitative spirometric phenotypes in severe early-onset chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is a common, complex disease associated with substantial morbidity and mortality. COPD is defined by irreversible airflow obstruction; airflow obstruction is typically determined by reductions in quantitative spirometric indices, including forced expiratory volume at 1 s (FEV(1)) and the ratio of FEV(1) to forced vital capacity (FVC). To identify genetic determinants of quantitative spirometric phenotypes, an autosomal 10-cM genomewide scan of short tandem repeat (STR) polymorphic markers was performed in 72 pedigrees (585 individuals) ascertained through probands with severe early-onset COPD. Multipoint variance-component linkage analysis (using SOLAR) was performed for quantitative phenotypes, including FEV(1), FVC, and FEV(1)/FVC. In the initial genomewide scan, significant evidence for linkage to FEV(1)/FVC was demonstrated on chromosome 2q (LOD score 4.12 at 222 cM). Suggestive evidence was found for linkage to FEV(1)/FVC on chromosomes 1 (LOD score 1.92 at 120 cM) and 17 (LOD score 2.03 at 67 cM) and to FVC on chromosome 1 (LOD score 2.05 at 13 cM). The highest LOD score for FEV(1) in the initial genomewide scan was 1.53, on chromosome 12, at 36 cM. After inclusion of 12 additional STR markers on chromosome 12p, which had been previously genotyped in this population, suggestive evidence for linkage of FEV(1) (LOD score 2.43 at 37 cM) to this region was demonstrated. These observations provide both significant evidence for an early-onset COPD-susceptibility locus on chromosome 2 and suggestive evidence for linkage of spirometry-related phenotypes to several other genomic regions. The significant linkage of FEV(1)/FVC to chromosome 2q could reflect one or more genes influencing the development of airflow obstruction or dysanapsis.

目的:观察稳定期慢性阻塞性肺疾病(COPD)患者营养不良与甲状腺激素、肺功能及血清白细胞介素(IL)-6、IL-18的关系。方法:选择2019年1月~2020年12月我院收治的稳定期COPD患者76例作为研究对象。根据患者的微型营养评定(MNA)评分将其分为营养不良组(n=31)和非营养不良组(n=45),比较两组患者的人口学资料、疾病相关因素,甲状腺激素[三碘甲状腺原氨酸(T3)、甲状腺激素(T4)、促甲状腺激素(TSH)]水平,肺功能[第1秒用力呼气量占预测值百分比(FEV1%pred)、第1秒用力呼气量与用力肺活量比值(FEV1/FVC)],血清IL-6、IL-18水平。分析MNA评分与甲状腺激素水平、肺功能及血清IL-6、IL-18水平的相关性。分析患者发生营养不良的危险因素。结果:营养不良组年龄高于非营养不良组(P<0.05)。营养不良组T3、T4、TSH、FEV1%pred、FEV1/FVC显著低于非营养不良组,血清IL-6、IL-18水平显著高于非营养不良组(P<0.05)。稳定期COPD患者的MNA评分与T3、T4、TSH、FEV1%pred、FEV1/FVC呈正相关,与IL-6、IL-18呈负相关(P<0.05)。多因素Logistic回归分析显示,年龄>60岁、T3≤1.60 nmol/L、T4≤73.00 nmol/L、TSH≤1.50 nmol/L、FEV1%pred≤60.00%、FEV1/FVC≤0.54、IL-6≥8.00 pg/mL、IL-18≥47.00 pg/mL是稳定期COPD患者营养不良的危险因素(P<0.05)。结论:稳定期COPD患者营养不良受多种因素影响,临床应针对相关因素给予有效干预,降低此类患者营养不良风险。     

Delayed apoptosis by neutrophils from COPD patients is associated with altered bak, bcl-xl, and mcl-1 mRNA expression

ABSTRACT: BACKGROUND: Delayed neutrophil apoptosis may be an important factor in the persistent inflammation associated with chronic obstructive pulmonary disease (COPD). Bcl-2 family proteins are important regulators of neutrophil apoptosis. We determined the mRNA levels of proapoptotic Bak and anti-aptototic Bcl-xl and Mcl-1 members of the Bcl-2 family in unstimulated peripheral blood neutrophils from patients with mild to moderate COPD and compared these to neutrophils from healthy controls. METHODS: Neutrophils were isolated from peripheral blood samples of 47 COPD patients (smokers: N = 24) and 47 healthy controls (smokers: N = 24). Percentages of apoptotic cells were determined at 4, 24, and 36 h for unstimulated neutrophils cultured in vitro. Neutrophil mRNA expression of Bak, Bcl-xl, and Mcl-1 was determined by real-time polymerase chain reaction (PCR). FEV1 (% predicted) and FVC were determined by spirometry and correlations between mRNA levels and lung function parameters were determined. RESULTS: The percentages of apoptotic cells among unstimulated neutrophils from COPD patients were significantly lower compared to cells from controls after 4, 24, and 36 h in culture; smoking history had only a minimal effect on these differences. Unstimulated neutrophils from COPD patients had significantly lower Bak mRNA expression and higher expressions of Bcl-xl and Mcl-1 mRNA than cells from healthy controls. Again, smoking history had only a minimal effect on these trends. Bak mRNA expression was significantly positively correlated with both %predicted FEV1 and the FEV1/FVC ratio, while Bcl-xl and Mcl-1 mRNA expressions were significantly negatively correlated with %predicted FEV1 and the FEV1/FVC ratio. CONCLUSIONS: The genes for pro-apoptotic Bak, and anti-apoptotic Bcl-xl and Mcl-1 may be important in regulating the delayed neutrophil apoptosis observed in COPD, which may contribute to COPD pathogenesis.

老年帕金森病患者睡眠障碍的危险因素及其对认知功能、心理状态和衰弱的影响

摘要 目的：探讨老年帕金森病（PD）患者睡眠障碍的危险因素,并观察睡眠障碍对认知功能、心理状态和衰弱的影响。方法：选取2018年3月~2021年9月期间中国人民解放军海军青岛特勤疗养中心收治的91例老年PD患者作为研究对象,根据是否存在睡眠障碍将入选的91例患者分为睡眠障碍组（n=56）及非睡眠障碍组（n=35）。采用蒙特利尔认知评估量表（MoCA）评估所有患者的认知功能状况。采用汉密尔顿焦虑量表（HAMA）、汉密尔顿抑郁量表（HAMD）评价患者焦虑、抑郁情况。采用Tilburg衰弱评估量表评估所有患者的衰弱情况。采用多因素Logistic回归分析探讨老年PD患者睡眠障碍的危险因素,并观察睡眠障碍对认知功能、心理状态和衰弱的影响。结果：睡眠障碍组的视空间与执行功能、语言、命名、延迟回忆、注意、抽象、定向评分及总分均低于非睡眠障碍组（P<0.05）。睡眠障碍组的HAMA、HAMD评分均高于非睡眠障碍组（P<0.05）。睡眠障碍组的心理衰弱、躯体衰弱、社会衰弱评分及总分均高于非睡眠障碍组（P<0.05）。多因素Losgistic回归分析结果显示：HAMA评分偏高、多巴丝肼片等效剂量偏高、HAMD评分偏高、Hcy偏高是老年PD患者睡眠障碍的危险因素（P<0.05）。结论：HAMA评分偏高、Hcy偏高、多巴丝肼片等效剂量偏高、HAMD评分偏高是老年PD患者睡眠障碍的危险因素。同时,睡眠障碍可加重老年PD患者的认知功能障碍和衰弱程度,增加抑郁焦虑情绪。     

Criterion validity of the Pittsburgh Sleep Quality Index: Investigation in a non-clinical sample

The objective of this study was to investigate the reliability and validity of the Pittsburgh Sleep Quality Index (PSQI) in a non-clinical sample consisting of younger and older adults. There has been little research validating the PSQI with respect to multinight recording as with actigraphy, and more validation is needed in samples not specifically selected for clinical disturbance. Also, the degree to which the PSQI scores may reflect depressive symptoms versus actual sleep disturbance remains unclear. One-hundred and twelve volunteers (53 younger and 59 older) were screened for their ability to perform treadmill exercises; inclusion was not based on sleep disturbance or depression. Internal homogeneity was evaluated by correlating PSQI component scores with the global score. Global and component scores were correlated with a sleep diary, actigraphy, and centers for epidemiological studies - depression scale scores to investigate criterion validity. Results showed high internal homogeneity. PSQI global score correlated appreciably with sleep diary variables and the depression scale, but not with any actigraphic sleep variables. These results suggest that the PSQI has good internal homogeneity, but may be less reflective of actual sleep parameters than a negative cognitive viewpoint or pessimistic thinking. The sleep complaints measured may often be more indicative of general dissatisfaction than of any specifically sleep-related disturbance.     

Sleep quality,chronotype, temperament and bipolar features as predictors of depressive symptoms among medical students

The assessment of risk factors is a crucial step in the prevention and treatment of affective disorders and should encompass personal dispositions. The aim of this study was to assess the value of chronotype and temperament as independent predictors of depressive symptoms among medical students. The study surveyed 140 students of the Faculty of Medicine with a battery of questionnaires: the Beck Depression Index (BDI), Hypomania Checklist 32 (HCL-32), Pittsburgh Sleep Quality Index (PSQI), Chronotype Questionnaire and Eysenck Personality Questionnaire Revised. The results were tested using Pearson’s correlation quotient and general linear model. Ten percent of the participants demonstrated a BDI score suggestive of clinically significant depressive symptoms. BDI score correlated positively with HCL-32 score. A rise in BDI was independently predicted by elevated Neuroticism and PSQI scores and morningness. Those effects were independent from each other and from other parameters of the model. The presence of depressive symptoms might be associated with bipolar features among medical students. Poor sleep quality predicted depressive symptoms, similarly to Neuroticism and independently of temperament and chronotype. Future studies on the associations between personal dispositions and mood disorders among medical students are required to help identify those at greater risk of developing affective illness. Effective prophylaxis and early intervention are warranted to ensure better treatment results.     

Toepassing van stemmingsvragenlijsten bij ouderen met alzheimerdementie (met of zonder taalstoornis) en hun informanten

Introduction

Alzheimer’s Dementia (AD) may be associated with symptoms of depression. In AD, problems of language expression or understanding will arise sooner or later. The aim of this study was to determine whether elderly persons with AD, with or without a language disorder, experience difficulties understanding and answering mood related questions. In addition to this, it was our object to test the validity of the answers of nurses as informants, on the mood of an elderly client.

Methods

53 elderly persons, living in care homes, and their nurses, took part in the study. 25 participants had been diagnosed with Alzheimer’s disease, 28 participants had no cognitive impairment. Language skills were tested using the SAN-test (Stichting Afasie Nederland) and subtests of the Aachen Aphasia Test (AAT). Mood was assessed with the Beck Depression Inventory-second edition (BDI-II-NL) and the Geriatric Depression Scale (GDS-30).

Results

There were no significant differences in scores on the mood related questionnaires between participants without cognitive impairment and participants with Alzheimer’s disease, with or without a language disorder. The correlation between self- and informant-rating was very limited. In general, nurses reported more depressive symptoms than the elderly persons did themselves. Disparities between self- and informant-ratings varied from informant scores overestimating low self-ratings of depression to informant scores underestimating high self-ratings.

Conclusion

Alzheimer’s disease, whether or not it is complicated by a language disorder, does not disturb the normal score distribution on either test (BDI or GDS). This means that elderly persons with Alzheimer’s disease are capable of adequately answering questions related to their own mood. However, considerable discrepancies were found between observer- and self-ratings of emotional wellbeing. Therefore it is important to not only take into account the information of an informant when testing for depression, but also the elderly person’s own assessment of their mood.

     

Sleep disturbances are associated with increased pain,disease activity,depression, and anxiety in ankylosing spondylitis: a case-control study

Introduction

Literature data suggest that sleep disturbances are prevalent among patients with ankylosing spondylitis (AS) and have a close correlation with pain. Other studies indicate that sleep disturbances are constantly accompanied by depression and anxiety in AS, but their interrelations are poorly understood. This study was designed to evaluate sleep disturbances and their association with demographic variables, pain, disease-specific variables, functional status, covering depression and anxiety in AS patients.

Methods

The 314 patients with AS and age- and sex-matched controls took part in the study, completed a battery of questionnaires, and participated in long-term follow-up. Blood samples were taken to measure C-reactive protein (CRP) and the erythrocyte sedimentation rate (ESR). The association among sleep, pain, disease activity, functional status, depression, and anxiety were assessed by using Pearson/Spearman correlations and multiple regression analysis.

Results

The Pittsburgh Sleep Quality Index (PSQI) score of the Chinese version was significantly higher in the AS group than in the control group (P = 0.020). Of the 314 patients with AS, 184 (58.6%) had a high risk for sleep disturbances. The PSQI score was associated with age, years of education, ESR, CRP, overall assessment of health, pain, morning stiffness, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), depression, and anxiety (all P < 0.001), but were not associated with disease duration, fingertip-to-floor distance, and Bath Ankylosing Spondylitis Metrology Index (BASMI) (P > 0.05). In hierarchic multiple regression analysis, the medical and psychological variables contributed significantly to the variance in sleep-disturbances scores, adding an additional 23.9% to the overall R² beyond that accounted for by demographic variables (R-square, 8.5%), resulting in a final R²of 42.6%. Multiple stepwise regression analysis revealed that anxiety was the maximal statistical contribution in predicting sleep disturbances (standardized coefficients, 0.287).

Conclusions

The prevalence of sleep disturbances in AS patients is higher than it is generally thought to be. Depression, anxiety, nocturnal pain, and total back pain are the major contributors of sleep disturbances in AS.     

放松训练对老年冠心病介入治疗患者围手术期心理应激干预效果研究

目的:探讨放松训练对老年冠心病介入治疗患者围手术期心理应激的干预效果。方法:选择2013年7月至2014年1月在某院接受介入治疗的老年冠心病患者120例为研究对象,随机分为干预组和对照组,各60例。对照组接受手术治疗和常规护理,干预组在对照组治疗方案的基础上采用放松训练进行围手术期心理干预。采用焦虑自评量表(SAS)、抑郁自评量表(SDS)、匹兹堡睡眠质量指数(PSQI)量表和生活满意度量表(SWLS)施测,并进行比较分析。结果:手术后放松训练干预组焦虑、抑郁和睡眠质量评分比手术前明显下降[(39.28±2.32),(41.68±2.76),(8.97±2.11)vs.(48.78±5.11),(54.37±6.68),(10.88±2.21),均P<0.01],显著低于对照组[(44.78±4.09),(49.08±3.58),(10.40±1.87)vs.(48.83±5.28),(54.40±3.72),(10.87±2.86),均P<0.01]。放松训练干预组手术后与手术前睡眠质量各分量表比较,除"催眠药物"和"日间功能障碍"2个因子外,其余各因子均有显著差异(均P<0.05)。放松训练干预组术后生活满意度量表评分明显高于术前[(23.27±4.61)vs.(20.17±4.99),P<0.01],显著高于对照组[(21.15±4.16)vs.(19.90±4.38),P<0.01]。结论:放松训练心理干预技术对接受介入治疗的老年冠心病患者的焦虑、抑郁情绪和睡眠质量具有良好的缓解和改善作用,可以降低患者的心理应激程度,提高患者术后的生活质量。
