Referral practices and treatment of obstructive sleep apnea in pregnancies with obesity.

Objective: Obstructive sleep apnea (OSA) affects maternal and neonatal health during pregnancy. This study aimed to identify characteristics and comorbidities associated with sleep clinic referral in high-risk pregnancies with Body Mass Index (BMI) ≥35 kg/m2. Method: Retrospective cohort study for individuals in a high-risk pregnancy clinic at a tertiary Australian hospital from 1 January to 31 December 2020 with BMI≥35 kg/m2. The primary outcome measure was sleep clinic referral. Exposure data included multiple comorbidities and formal tools (Epworth Sleepiness Scale and STOP-BANG). Multivariable analysis was used to identify factors associated with referral. Descriptive data on barriers to diagnosis and treatment were collected. Results: Of 161 pregnant individuals, 38.5% were screened using formal tools and 13.7% were referred to sleep clinic. Having STOP-BANG performed was associated with sleep clinic referral (Odds Ratio: 18.04, 95% Confidence Interval:4.5-71.7, p < 0.001). No clinical characteristics were associated with the likelihood of performing STOP-BANG. The COVID-19 pandemic was a treatment barrier for three individuals. Conclusions: Current screening practices identify pregnant individuals with the highest pre-test probability of having OSA. Future research should evaluate real-world strategies to improve identification and management in this high-risk population.

Developing a Decision Aid for Clinical Obesity Services in the Real World: the DACOS Nationwide Pilot Study.

PURPOSE: The purpose of this study is to develop a decision aid tool using "real-world" data within the Australian health system to predict weight loss after bariatric surgery and non-surgical care. MATERIALS AND METHODS: We analyzed patient record data (aged 16+years) from initial review between 2015 and 2020 with 6-month (n=219) and 9-/12-month (n=153) follow-ups at eight clinical obesity services. Primary outcome was percentage total weight loss (%TWL) at 6 months and 9/12 months. Predictors were selected by statistical evidence (p<0.20), effect size (±2%), and clinical judgment. Multiple linear regression and bariatric surgery were used to create simple predictive models. Accuracy was measured using percentage of predictions within 5% of the observed value, and sensitivity and specificity for predicting target weight loss of 5% (non-surgical care) and 15% (bariatric surgery). RESULTS: Observed %TWL with bariatric surgery vs. non-surgical care was 19% vs. 5% at 6 months and 22% vs. 5% at 9/12 months. Predictors at 6 months with intercept (non-surgical care) of 6% include bariatric surgery (+11%), BMI>60 (-3%), depression (-2%), anxiety (-2%), and eating disorder (-2%). Accuracy, sensitivity, and specificity were 58%, 69%, and 56%. Predictors at 9/12 months with intercept of 5% include bariatric surgery (+15%), type 2 diabetes (+5%), eating disorder (+4%), fatty liver (+2%), atrial fibrillation (-4%), osteoarthritis (-3%), sleep/mental disorders (-2-3%), and ≥10 alcohol drinks/week (-2%). Accuracy, sensitivity, and specificity were 55%, 86%, and 53%. CONCLUSION: Clinicians may use DACOS to discuss potential weight loss predictors with patients after surgery or non-surgical care.

Weight change in chronic kidney disease: Association with mortality and kidney function.

Background: Excess body weight is a risk factor for the progression of chronic kidney disease (CKD), but weight loss in CKD has been associated with higher mortality. Consequently, blanket weight loss recommendations in this population are controversial. Little data is available on the patterns of weight-change in CKD. The authors aimed to describe weight-changes in moderate/severe CKD and explore associations with mortality and renal endpoints in patients with overweight and obesity. Methods: Non-dialysis Canberra Hospital patients with estimated glomerular filtration (eGFR) < 60 mL/min/1.73 m2 and body mass index (BMI) ≥25 kg/m2 were followed for up to 5.5 years. Weight-change ≥5% was considered clinically significant. The renal endpoint was defined as the commencement of dialysis or transplant or a ≥40% fall in eGFR. Relationships between weight-change in the first year of follow-up and mortality or the renal endpoint were assessed using Cox-regression. Results: Three hundred ten patients (median age 75, median BMI 31 kg/m2) were identified. 68% had Stage-4 CKD at baseline. Over 4.4-years median follow-up, 128 died and 140 had significant weight-change. During the first year of follow-up, 42 patients lost and 23 gained ≥5% body weight, of whom only 3 had intentionally lost weight. On multivariate regression, significant weight loss/gain at 1-year was associated with 2.74 (p < 0.0005) and 2.67 (p = 0.003) hazard of subsequent death and with 2.51 (p = 0.004) and 2.20 (p = 0.05) hazard of the renal endpoint respectively. There was no association between baseline eGFR and subsequent weight change. Conclusions: Patients with moderate/severe CKD experience significant weight-change, but this has no relationship to baseline kidney function. Significant weight-change is associated with higher subsequent mortality and loss of kidney function, but this association is likely significantly affected by confounding.

Obstructive sleep apnea in aboriginal Australians: polysomnographic outcomes and symptom perception post-continuous positive airway pressure implementation.

Study Objectives: Obstructive sleep apnea (OSA) is reported to be highly prevalent among Aboriginal Australians. However, no studies have assessed the implementation and efficacy of continuous positive airway pressure (CPAP) therapy in this population. Hence, we compared the clinical, self-reported perception of sleep quality and polysomnographic (PSG) characteristics among Aboriginal patients with OSA. Methods: Adult Aboriginal Australians who underwent both diagnostic (Type 1 and 2) and in-lab CPAP implementation studies were included. Results: Total of 149 patients were identified (46% female, median age 49 years, body mass index 35 kg/m2). The OSA severity was 6% mild, 26% moderate, and 68% severe on the diagnostic PSG. On application of CPAP, there were significant improvements in; total arousal index (diagnostic 29 to 17/h on CPAP), total apnea-hypopnea index (AHI) (diagnostic 48 to 9/h on CPAP), non-rapid eye movement AHI (diagnostic 47 to 8/h on CPAP), rapid eye movement (REM) AHI (diagnostic 56 to 8/h on CPAP) and oxygen saturation (SpO2) nadir (diagnostic 77% to 85% on CPAP) (p < 0.001 for each). Following a single night of CPAP, 54% of patients reported sleeping "better than normal" compared to 12% following the diagnostic study (p = 0.003). In multivariate regression models, males had a significantly lesser change in REM AHI than females (5.7 events/hour less change (IQR 0.4, 11.1), p = 0.029). Conclusions: There is substantial improvement in several sleep-related domains on the application of CPAP among Aboriginal patients with a good initial acceptance of treatment. Whether the positive impact observed in this study translates to better sleep health outcomes with long-term adherence to CPAP therapy is yet to be assessed.

Assessing service provision and outcomes at the Canberra Obesity Management Service: A retrospective chart review.

OBJECTIVE: This study aimed to evaluate the multidisciplinary care model of the Canberra Obesity Management Service (COMS) with regard to patient demographics and clinical outcomes, particularly in comparison with previous COMS outcome reviews. METHODS: A retrospective chart review was carried out on all patients attending an initial assessment at COMS between July 2018 and June 2019. Existing patients attending follow-up reviews were excluded so as to avoid repeating analyses of data from previous COMS reviews. Patient data were recorded and deidentified and underwent descriptive analyses. RESULTS: A total of 234 patients with a mean age of 45.6 (SD = 13.9) years, mean BMI of 50.1 kg/m2 (SD = 8.5), and a female majority (72.2%) were analyzed. Of the 165 patients who attended follow-up appointments, 27.9% experienced ≥10% weight loss (46/165). Sleeve gastrectomy was associated with the largest mean weight reduction (15.6% at 6 months [n = 18]). CONCLUSIONS: Compared with previous COMS studies, both the throughput and proportion of participants achieving clinically meaningful weight reduction were observed to have increased. Further studies assessing service cost-effectiveness, the development of standardized treatment pathways, and the use of a systematic data collection system would be valuable in allowing comparison between outcomes with similar obesity services in Australia and internationally.

Using a consensus acupoints regimen to explore the relationship between acupuncture sensation and lumbar spinal postoperative analgesia: A retrospective analysis of prospective clinical cooperation.

OBJECTIVE: This study evaluated the effectiveness of acupuncture treatment on postoperative pain in patients with degenerative lumbar spine disease, and explored the relationship between the postoperative analgesic effect of acupuncture and the sensation of acupuncture experienced by the patients. METHODS: This retrospective study analyzed the medical records of 97 patients who had undergone an operation by the same surgeon due to degenerative lumbar disease. These patients were divided into acupuncture group (n = 32), patient-controlled analgesia (PCA) group (n = 27), and oral analgesia group (n = 38) according to the different postoperative analgesic methods. During their hospitalization, patients completed daily evaluations of their pain using a visual analogue scale (VAS), and injection times of supplemental meperidine were recorded. Also, the Chinese version of the Massachusetts General Hospital Acupuncture Sensation Scale (C-MASS) was used in the acupuncture group. RESULTS: Each of the three treatment groups showed significant reductions in postoperative pain, as shown by reduced VAS scores. The acupuncture group, however, had less rebound pain (P < 0.05) than the other two groups. Both the acupuncture and PCA groups experienced acute analgesic effects that were superior to those in the oral analgesia group. In addition, the higher the C-MASS index on the second day after surgery, the lower the VAS score on the fourth day after surgery. There was also a significant difference in the "dull pain" in the acupuncture sensation. CONCLUSION: The results demonstrated that acupuncture was beneficial for postoperative pain and discomfort after simple surgery for degenerative spinal disease. It is worth noting that there was a disproportionate relevance between the patient's acupuncture sensation and the improvement of pain VAS score.

The association of age with continuous positive airway pressure ventilation acceptance in an outpatient cohort of patients with obstructive sleep apnea.

STUDY OBJECTIVES: This study examined the association between age and continuous positive airway pressure (CPAP) acceptance in a consecutive series of patients with obstructive sleep apnea being managed in a physician-led outpatient CPAP acclimatization program in Canberra, Australia. METHODS: We performed a retrospective consecutive case series analysis of registry data collected from patients attending the Canberra Hospital PAP Acclimatization Clinic between 2011 and 2019. Data on patient demographics, diagnostic polysomnography results, CPAP device download parameters during acclimatization, and overall CPAP acceptance at the end of acclimatization were extracted from the Clinic Registry. Analysis of variance and chi-square were used to assess for associations between patient age, CPAP acceptance, and other clinical characteristics. Univariate and stepwise multiple logistic regression was used to identify predictors of CPAP acceptance. RESULTS: We found that 1,075 consecutive CPAP trials among 1,043 patients were eligible for inclusion. CPAP acceptance was lower in those aged > 75 years compared with those aged ≤ 75 years (odds ratio: 0.57; 95% confidence interval, 0.36-0.92; P = .02). Patients aged > 75 years had lower body mass index, had higher initial and final visit 95th percentile mask leak, and were less likely to be CPAP naïve. Using univariate regression, younger age, severe obstructive sleep apnea, obesity, shorter trial duration, more clinic visits, higher initial visit CPAP usage, and lower final visit mask leak were predictors of CPAP acceptance. In a multiple logistic regression model, younger age, severe obstructive sleep apnea, shorter trial duration, more clinic visits, higher first visit usage, and lower final visit leak predicted acceptance. CONCLUSIONS: Older age is associated with lower CPAP acceptance. The factors contributing to this association are unclear and require further investigation.

The association of age with continuous positive airway pressure ventilation acceptance in an outpatient cohort of patients with obstructive sleep apnea. J Clin Sleep Med. 2022;18(1):217-224.

Mental illness as a predictor of patient attendance and anthropometric changes: observations from an Australian publicly funded obesity management service.

OBJECTIVE: Obesity is associated with co-morbid mental illness. The Canberra Obesity Management Service (OMS) supports adults with severe obesity who have the psychosocial capacity to engage. This study will determine whether mental illness is a predictor of OMS attendance and anthropometric changes. METHOD: A retrospective audit was performed from July 2016 to June 2017. Baseline characteristics, attendance and anthropometrics were stratified according to the presence of mental illness. Outcomes included weight stabilisation and clinically significant weight loss. Descriptive analyses were performed. RESULTS: Mental illness was present in 60/162 patients (37%). Attendance was similar for those with and without mental illness. Patients with mental illness had twice as many co-morbidities (p = .001). Depressive disorders were most common (n = 28, 47%). Anxiety, schizophrenia spectrum and other psychotic disorders, and trauma- and stressor-related disorders also featured. Weight stabilisation was achieved by 25 patients (66%) with mental illness and 25 (35%) without. Clinically significant weight loss was observed in 10 patients (26%) with and 26 (40%) without mental illness. CONCLUSION: The presence of mental illness did not impact OMS attendance or weight stabilisation. The higher rate of co-morbidities in those with mental illness highlights the challenges faced by this vulnerable population.

Adding Telephone and Text Support to an Obesity Management Program Improves Behavioral Adherence and Clinical Outcomes. A Randomized Controlled Crossover Trial.

BACKGROUND: Behavioral treatment strategies improve adherence to lifestyle intervention for adults with obesity, but can be time and resource intensive when delivered via traditional face-to-face care. This study aimed to investigate the efficacy and optimal timing of using telephone calls and text message as adjunctive tools to support a community-based obesity management program. METHOD: This 8-month randomized controlled crossover trial recruited 61 adults with class III obesity (BMI > 40 kg/m2) enrolled in a publicly funded obesity management service (OMS). Participants were randomly assigned to receive telephone and text message support in addition to standard OMS care, or standard OMS care alone. After 4 months, participants crossed over to the alternative sequence. The technological support was based on self-determination theory. Outcome measures included diet, physical activity, anthropometry, self-efficacy, and treatment self-regulation. RESULTS: Telephone and text message support improved lifestyle intervention adherence and clinical outcomes when compared with standard care. Participants who received the intervention in the first 4-month period lost 4.87 kg, compared with no weight loss (+ 0.38 kg) in the standard care only group. There was no evidence to indicate an optimal timing of the intervention, with both groups achieving significant results by the end of the intervention. CONCLUSION: These results suggest a high degree of promise for the incorporation of telephone and text message support into community-based obesity management services. The findings have the potential to improve existing practices and reduce the burden on the health care system by demonstrating a resource-effective improvement to obesity management service delivery.

Determining patient attendance, access to interventions and clinical outcomes in a publicly funded obesity programme: Results from the Canberra Obesity Management Service.

Multi-disciplinary specialist services have a crucial role in the management of patients with obesity. As demand for these services increases, so too does the need to monitor individual service performance and compare outcomes across multiple sites. This paper reports on results from the publicly funded Canberra Obesity Management Service. A descriptive observational study was conducted on new patients who attended an initial medical review from July 2016 to June 2017. Baseline characteristics, comorbidities, attendance, service utilization and outcomes were collated until June 2018. Of the 162 patients identified, 64% continued to attend beyond initial medical review. Dietetics was the most commonly accessed allied health service, followed by exercise physiology and psychology. Very low-energy diet was the most commonly trialled intensive intervention, followed by pharmacotherapy and bariatric surgery. Mean baseline weight for those who continued beyond initial medical review was 142.0 kg (SD 26.6 kg), with a mean weight change of -6.2 kg (SD 10.2 kg) and a mean change in percentage body weight of -5% (SD 7%). Clinically significant weight loss was achieved in 36% of these patients, with a further 47% achieving weight stabilization. Mean Depression, Anxiety and Stress Scale scores reduced from 8-6-8 to 7-5-5, and mean Epworth Sleepiness Scale scores decreased from 8/24 to 6/24. Polysomnography referrals were made for 37% of all new patients, 87% of whom were diagnosed with varying degrees of obstructive sleep apnoea. We present these findings in the hope that they may serve as an example for data collection, individual service monitoring and comparison across multiple obesity services.

Utilization Pattern of Traditional Chinese Medicine among Fracture Patients: A Taiwan Hospital-Based Cross-Sectional Study.

Traditional Chinese medicine (TCM) divides fracture treatment into three stages. Many TCM herbs and formulas have been used to treat fractures for thousands of years. However, research regarding the Chinese herbal products (CHPs) that should be used at different periods of treatment is still lacking. This study aims to identify the CHPs that should be used at different periods of treatment as well as confirm the TCM theory of fracture periods medicine. We used prescriptions of TCM outpatients with fracture diagnoses analyzed using the Chang Gung Research Database (CGRD) from 2000 to 2015. According to the number of days between the date of the fracture and the clinic visit date, all patients were assigned to one of three groups. Patients with a date gap of 0-13 days were assigned to the early period group; those with a date gap of 14-82 days were assigned to the middle period group; and those with a date gap of 83-182 days were assigned to the late period group. We observed the average number of herbal formulas prescribed by the TCM doctor at each visit was 2.78, and the average number of single herbs prescribed was 6.47. The top three prescriptions in the early fracture period were Zheng-gu-zi-jin-dang, Shu-jing-huo-xue-tang, and Wu-ling-san. In the middle fracture period, the top three formulas were Zheng-gu-zi-jin-dang, Shu-jing-huo-xue-tang, and Zhi-bai-di-huang-wan. In the late fracture period, the top three formulas were Shu-jing-huo-xue-tang, Gui-lu-er-xian-jiao, and Du-huo-ji-sheng-tang. The main single herbs used in the early fracture period were Yan-hu-suo, Gu-sui-bu, and Dan-shen. From the middle to the late period, the most prescribed single herbs were Xu-duan, Gu-sui-bu, and Yan-hu-suo. We concluded that the results showed that the CGRD utilization pattern roughly meets the TCM theory at different fracture periods.

"They can rest at home": an observational study of patients' quality of sleep in an Australian hospital.

BACKGROUND: Poor sleep is known to adversely affect hospital patients' recovery and rehabilitation. The aim of the study was to investigate the perceived duration and quality of patient sleep and identify any environmental factors associated with patient-reported poor sleep in hospital. METHOD: A cross-sectional study was conducted involving 15 clinical units within a 672-bed tertiary-referral hospital in Australia. Semi-structured interviews to determine perceptions of sleep quantity and quality and factors that disturb nocturnal sleep were conducted with patients and nursing staff. Environmental noise, light and temperature were monitored overnight, with concurrent logging of noise sources by observers. RESULTS: Patients reported a mean reduction in hospital sleep duration, compared to home, of 1.8 h (5.3 vs. 7.1 h; p < 0.001). The proportions of patients reporting their sleep quality to be poor/very poor, fair and of good quality were 41.6, 34.2 and 24.2% respectively. Patients reported poorer sleep quality than nurses (p < 0.05). Patients, nurses and observers all reported the main factors associated with poor sleep as clinical care interventions (34.3%) and environmental noise (32.1%). Noise levels in all 15 clinical areas exceeded WHO recommended levels of < 30 dB [A] by 36.7 to 82.6%, with peak noise levels of 51.3 to 103.3 dB (A). CONCLUSION: Hospital in-patients are exposed to factors which reduce the duration and quality of their sleep. These extrinsic factors are potentially modifiable through behaviour change and reconfiguration of the clinical environment. The findings from this study provided the foundation for a quality improvement project currently underway to improve patients' sleep.

Investigating the application of motion accelerometers as a sleep monitoring technique and the clinical burden of the intensive care environment on sleep quality: study protocol for a prospective observational study in Australia.

INTRODUCTION: Sleep is a state of quiescence that facilitates the significant restorative processes that enhance individuals' physiological and psychological well-being. Patients admitted to the intensive care unit (ICU) experience substantial sleep disturbance. Despite the biological importance of sleep, sleep monitoring does not form part of standard clinical care for critically ill patients. There exists an unmet need to assess the feasibility and accuracy of a range of sleep assessment techniques that have the potential to allow widespread implementation of sleep monitoring in the ICU. KEY MEASURES: The coprimary outcome measures of this study are to: determine the accuracy and feasibility of motion accelerometer monitoring (ie, actigraphy) and subjective assessments of sleep (nursing-based observations and patient self-reports) to the gold standard of sleep monitoring (ie, polysomnography) in evaluating sleep continuity and disturbance. The secondary outcome measures of the study will include: (1) the association between sleep disturbance and environmental factors (eg, noise, light and clinical interactions) and (2) to describe the sleep architecture of intensive care patients. METHODS AND ANALYSIS: A prospective, single centre observational design with a within subjects' assessment of sleep monitoring techniques. The sample will comprise 80 adults (aged 18 years or more) inclusive of ventilated and non-ventilated patients, admitted to a tertiary ICU with a Richmond Agitation-Sedation Scale score between +2 (agitated) and -3 (moderate sedation) and an anticipated length of stay >24 hours. Patients' sleep quality, total sleep time and sleep fragmentations will be continuously monitored for 24 hours using polysomnography and actigraphy. Behavioural assessments (nursing observations) and patients' self-reports of sleep quality will be assessed during the 24-hour period using the Richards-Campbell Sleep Questionnaire, subjective sleepiness evaluated via the Karolinska Sleepiness Scale, along with a prehospital discharge survey regarding patients' perception of sleep quality and disturbing factors using the Little Sleep Questionnaire will be undertaken. Associations between sleep disturbance, noise and light levels, and the frequency of clinical interactions will also be investigated. Sound and luminance levels will be recorded at 1 s epochs via Extech SDL600 and SDL400 monitoring devices. Clinical interactions will be logged via the electronic patient record system Metavision which documents patient monitoring and clinical care. ETHICS AND DISSEMINATION: The relevant institutions have approved the study protocol and consent procedures. The findings of the study will contribute to the understanding of sleep disturbance, and the ability to implement sleep monitoring methods within ICUs. Understanding the contribution of a clinical environment on sleep disturbance may provide insight into the need to address clinical environmental issues that may positively influence patient outcomes, and could dispel notions that the environment is a primary factor in sleep disturbance. The research findings will be disseminated via presentations at national and international conferences, proceedings and published articles in peer-reviewed journals.

The nocturnal acoustical intensity of the intensive care environment: an observational study.

BACKGROUND: The intensive care unit (ICU) environment exposes patients to noise levels that may result in substantial sleep disruption. There is a need to accurately describe the intensity pattern and source of noise in the ICU in order to develop effective sound abatement strategies. The objectives of this study were to determine nocturnal noise levels and their variability and the related sources of noise within an Australian tertiary ICU. METHODS: An observational cross-sectional study was conducted in a 24-bed open-plan ICU. Sound levels were recorded overnight during three nights at 5-s epochs using Extech (SDL 600) sound monitors. Noise sources were concurrently logged by two research assistants. RESULTS: The mean recorded ambient noise level in the ICU was 52.85 decibels (dB) (standard deviation (SD) 5.89), with a maximum noise recording at 98.3 dB (A). All recorded measurements exceeded the WHO recommendations. Noise variability per minute ranged from 9.9 to 44 dB (A), with peak noise levels >70 dB (A) occurring 10 times/hour (SD 11.4). Staff were identified as the most common source accounting for 35% of all noise. Mean noise levels in single-patient rooms compared with open-bed areas were 53.5 vs 53 dB (p = 0.37), respectively. CONCLUSION: Mean noise levels exceeded those recommended by the WHO resulting in an acoustical intensity of 193 times greater than the recommended and demonstrated a high degree of unpredictable variability, with the primary noise sources coming from staff conversations. The lack of protective effects of single rooms and the contributing effects that staffs have on noise levels are important factors when considering sound abatement strategies.

Sleep apnea prevalence in chronic kidney disease - association with total body water and symptoms.

BACKGROUND: Sleep apnea is common and associated with poor outcome in severe chronic kidney disease, but validated screening tools are not available. Our objectives were to determine the prevalence of sleep apnea in this population, to assess the validity of screening for sleep apnea using an ApneaLink device and to investigate the relationship of sleep apnea to; symptoms, spirometry and body water. METHODS: Patients with glomerular filtration rate ≤30 mL/min/1.73 m2, whether or not they were receiving haemodialysis, were eligible for enrolment. Participants completed symptom questionnaires, performed an ApneaLink recording and had total body water measured using bioimpedance. This was followed by a multi-channel polysomnography recording which is the gold-standard diagnostic test for sleep apnea. RESULTS: Fifty-seven participants were enrolled and had baseline data collected, of whom only 2 did not have sleep apnea. An apnea hypopnea index ≥30/h was found in 66% of haemodialysis and 54% of non-dialysis participants. A central apnea index ≥5/h was present in 11 patients, with only one dialysis patient having predominantly central sleep apnea. ApneaLink underestimated sleep apnea severity, particularly in the non-dialysis group. Neither total body water corrected for body size, spirometry, subjective sleepiness nor overall symptom scores were associated with sleep apnea severity. CONCLUSIONS: This study demonstrates a very high prevalence of severe sleep apnea in patients with chronic kidney disease. Sleep apnea severity was not associated with quality of life or sleepiness scores and was unrelated to total body water corrected for body size. Routine identification of sleep apnea with polysomnography rather than screening is more appropriate in this group due to the high prevalence.

Acupuncture Therapy and Incidence of Depression After Stroke.

BACKGROUND AND PURPOSE: We investigated whether use of acupuncture within a 3-month poststroke period after hospital discharge is associated with reduced risk of depression. METHODS: This cohort study included 16 046 patients aged ≥18 years with an initial hospitalization for stroke during 2000 and 2012 in the claims database of a universal health insurance program. Patients who had received acupuncture therapies within 3 months of discharge were defined as acupuncture users (n=1714). All patients were followed up for incidence of depression until the end of 2013. We assessed the association between use of acupuncture and incidence of depression using Cox proportional hazards models in all subjects and in propensity score-matched samples consisting of 1714 pairs of users and nonusers. RESULTS: During the follow-up period, the incidence of depression per 1000 person-years was 11.1 and 9.7 in users and nonusers, respectively. Neither multivariable-adjusted Cox models (hazard ratio, 1.04; 95% confidence interval, 0.84-1.29) nor the propensity score-matching model (hazard ratio, 1.06; 95% confidence interval, 0.79-1.42) revealed an association between use of acupuncture and incidence of depression. CONCLUSIONS: In patients admitted to hospital for stroke, acupuncture therapy within 3 months after discharge was not associated with subsequent incidence of depression.

Manipulation Therapy Relieved Pain More Rapidly Than Acupuncture among Lateral Epicondylalgia (Tennis Elbow) Patients: A Randomized Controlled Trial with 8-Week Follow-Up.

Radial bone adjustment manipulation treatment may be effective to reduce pain rapidly in lateral epicondylalgia patients and the pathological tension in the biceps brachii muscle is highly concerned. To prove this hypothesis, we conducted a randomized controlled trial and included 35 patients with lateral epicondylalgia for more than 2 months. Either manipulation treatment (n = 16) or acupuncture (n = 19) was given to these patients for 2 weeks and all patients' symptoms were followed up for 8 weeks after treatment. Both groups demonstrated changes in pain VAS score, grip strength, and DASH questionnaire. Lateral epicondylalgia patients who received manipulation treatment felt pain relief sooner than those who had acupuncture treatments during the first few treatments. However, both acupuncture and manipulation are effective, while the difference has no significance at the 8-week follow-up. The trial was registered with Current Controlled Trials ISRCTN81308551 on 5 February 2016.

Control of OSA during automatic positive airway pressure titration in a clinical case series: predictors and accuracy of device download data.

STUDY OBJECTIVES: To investigate the factors associated with physiologic control of obstructive sleep apnea (OSA) during automatic positive airway pressure (APAP) titration in a clinical series. To also assess the usefulness of apnea-hypopnea index (AHI) data downloaded from the APAP device (Dev AHI). DESIGN: Retrospective review of a consecutive series of patients with OSA who underwent APAP titration (Autoset Spirit, ResMed, Bella Vista, New South Wales, Australia ) with simultaneous polysomnographic (PSG) monitoring in the sleep laboratory. SETTING: Tertiary sleep clinic. PARTICIPANTS: There were 190 consecutive patients with OSA referred for APAP titration. MEASUREMENTS AND RESULTS: There were 58% of patients who achieved optimal or good control of OSA (titration PSG AHI < 10, or at least 50% reduction in AHI if diagnostic AHI < 15/hr) during APAP titration. The independent predictors of titration PSG AHI were a history of cardiac disease and elevated central apnea and arousal indices during the diagnostic study. Although the median and interquartile range (IQR) AHI from the device (7.0, 3.9-11.6 events/hr) was only slightly less than the PSG AHI (7.8, 3.9-14.4 events/hr, P = 0.04) during titration, case-by-case agreement between the two measures was poor (chi-square < 0.001). CONCLUSION: In a clinical sample control of OSA during APAP titration is often poor, and close clinical follow-up is particularly needed in patients with a history of cardiac disease or with high arousal or central apnea indices on the diagnostic study. Device AHI does not reliably assess control during APAP titration, and PSG assessment may be required if clinical response to treatment is poor. The findings relate to the ResMed AutoSet device and may not apply to other devices.

Intravenous ondansetron as antiemetic prophylaxis for postoperative nausea and vomiting after shoulder arthroscopy.

BACKGROUND: Nausea and vomiting are common chief postoperative complaints. The clinical literature indicates that postoperative nausea and vomiting (PONV) is common after orthopedic surgery. This study examines the clinical therapeutic efficacy of Ondansetron injected intravenously before the end of shoulder arthroscopy as antiemetic prophylaxis to help reduce the incidence of PONV. METHODS: Participants were identified through retrospective chart review and patients undergoing shoulder arthroscopy performed by the same orthopedic surgeon at the same hospital from 2005 to 2009 were analyzed. Subjects were classified into two groups based on whether Ondansetron was given. Differences in the incidence of PONV among the two groups were compared. Basic patient information, anesthesia records, and surgical records were obtained, as well as records on PONV, postoperative pain intensity, and postoperative analgesic injections within 24 hours after surgery. RESULTS: The study involved 90 patients. The Group A contained 34 patients who did not receive Ondansetron, and the Group B contained 56 patients who were given Ondansetron. Analytical results for the postoperative 24 hour period showed a significant difference in the incidence of vomiting between the two groups, with a lower incidence (p < 0.05) for the. Group B. However there was no significant difference in the incidence of nausea between the two groups in the same postoperative 24 hour period, although there was a trend of a lower incidence in the Group B (p = 0.17). The overall incidence of PONV during the 24-hour period was lower in the Group B (14%) than the Group A (32%), and the Group B demonstrated lower pain intensity and lower analgesic injection needs. CONCLUSION: Routine intravenous injection of Ondansetron 30 minutes before completion of shoulder arthroscopy can reduce the incidence of vomiting and overall PONV in patients. Additionally, the patients using Ondansetron demonstrated lower pain intensity and lower analgesic injection needs than the control group.
