Association between calf circumference and incontinence in Chinese elderly - BMC Public HealthBackground The objective of this study was to analyze the association between calf circumference and incontinence in Chinese elderly, and to find out the maximal cut-off point by gender for the use of calf circumference in screening for incontinence. Methods In this study, participants were from the 2018 Chinese Longitudinal Healthy Longevity Survey (CLHLS). The maximal calf circumference cut-off point and other incontinence-related risk factors were explored using receiver operating characteristic (ROC) curves and logistic regression analysis. Results The study included 14,989 elderly people (6,516 males and 8,473 females) over 60. The prevalence of incontinence in elderly males was 5.23% (341/6,516), significantly lower than females, which was 8.31% (704/8,473) (p | 0.001). There was no correlation between calf circumference | 34 cm in males and | 33 cm in females and incontinence after adjusting the confounders. We further stratified by gender to predict incontinence in elderly based on the Youden index of ROC curves. We found the association between calf circumference and incontinence was the strongest when the cut-off points were | 28.5 cm for males and | 26.5 cm for females, with an odds rate (OR) value of 1.620 (male, 95%CI: 1.197–2.288) and 1.292 (female, 95%CI: 1.044–1.600) after adjusting the covariates, respectively. Conclusions Our study suggests that calf circumference | 28.5 cm in males and | 26.5 cm in females is a risk factor for incontinence in the Chinese elderly population. Calf circumference should be measured in routine physical examination, and timely interventions should be made to reduce the risk of incontinence in subjects with calf circumference less than the threshold.

Changes in maternal heart rate in delayed post-partum preeclampsia - BMC Women's HealthAim Delayed-onset postpartum preeclampsia (PET) is defined as a new diagnosis of preeclampsia presenting 48 h to 6 weeks postpartum. This disorder is infrequent and associated with a higher incidence of complications as compared to antepartum PET. There seems to be a need to further characterize this disorder. The aim of the study was to investigate the difference of maternal heart rate in women with delayed onset postpartum preeclampsia as compared to healthy controls. Methods The medical files of all women who were readmitted with delayed onset postpartum preeclampsia during 2014–2020 were reviewed. Data on maternal physiological characteristics were compared to healthy control group of women at the same post-partum day, with uncomplicated pregnancies. Results Included 45 women with the diagnosis of delayed onset of preeclampsia at 6.3 ± 2.86 post-partum day. As compared to controls (n = 49), women with delayed post-partum were older, 34.6 ± 5.4 vs. 32.3 ± 4.7 years, p = 0.003. There were no differences between groups regarding maternal gravidity, parity, BMI (kg/m2) or Hb level at delivery day. Women with delayed post-partum preeclampsia had lower mean pulse rate as compared to controls, 58 ± 15 bpm vs. 83 ± 11.6 bpm, respectively, P | 0.0001. Only 17% of the women in the delayed onset group had pulse rate above 70 bpm as compared to 83% in the control group. Conclusions Maternal low heart rate in cases with delayed onset of post-partum preeclampsia is an important clinical characteristic that may reflect baroreceptors response to maternal hypertension.

Effects of music therapy as an alternative treatment on depression in children and adolescents with ADHD by activating serotonin and improving stress coping ability - BMC Complementary Medicine and TherapiesObjective The objective of this study was to determine the effect of music therapy as an alternative treatment on depression in children and adolescents with attention-deficit hyperactivity disorder (ADHD) by activating serotonin (5-HT) and improving stress coping ability. Methods This study is designed based on randomization method. A total of 36 subjects participated in the experiment, consisting of an ADHD control group (n=18) and ADHD music therapy group (n=18). The ADHD control group received standard care, while the ADHD music therapy group received music therapy and standard care. The ADHD music therapy group received both active music therapy (improvisation) and receptive music therapy (music listening) for 50 minutes, twice a week, for 3 months: a total of 24 times. From a neurophysiological perspective, changes in depression and stress were tracked by measuring 5-HT secretion, cortisol expression, blood pressure (BP), heart rate (HR), and CDI and DHQ psychological scales. Results The ADHD music therapy group’s 5-HT secretion increased (p | 0.001), whereas cortisol expression (p | 0.001), BP (p | 0.001) and HR (p | 0.001) decreased. The CDI and DHQ psychological scales also showed positive changes (p | 0.01 and p | 0.001, respectively). However, the ADHD Con G’s (who did not receive music therapy) 5-HT secretion did not increase, whereas cortisol expression, BP, and HR did not decrease. In addition, the CDI and DHQ psychological scales did not display positive changes. Conclusions In conclusion, the application of music therapy as an alternative treatment for ADHD children and adolescents showed positive neurophysiological and psychological effects. Therefore, this study would like to propose a new alternative to medicine for preventing and treating depression through various uses of music therapy. n=36. A true believer in the law of small numbers. On the other hand, music therapy won't cause harm. Perhaps it's true, but lets to a proper n for a free range species like humans. Reasonably so. A dubious intervention in a dubious diagnosis. Well adrift from any clinical relevsnce.

Prognostic assessment capability of a five-gene signature in pancreatic cancer: a machine learning based-study - BMC GastroenterologyBackground A prognostic assessment method with good sensitivity and specificity plays an important role in the treatment of pancreatic cancer patients. Finding a way to evaluate the prognosis of pancreatic cancer is of great significance for the treatment of pancreatic cancer. Methods In this study, GTEx dataset and TCGA dataset were merged together for differential gene expression analysis. Univariate Cox regression and Lasso regression were used to screen variables in the TCGA dataset. Screening the optimal prognostic assessment model is then performed by gaussian finite mixture model. Receiver operating characteristic (ROC) curves were used as an indicator to assess the predictive ability of the prognostic model, the validation process was performed on the GEO datasets. Results Gaussian finite mixture model was then used to build 5-gene signature (ANKRD22, ARNTL2, DSG3, KRT7, PRSS3). Receiver operating characteristic (ROC) curves suggested the 5-gene signature performed well on both the training and validation datasets. Conclusions This 5-gene signature performed well on both our chosen training dataset and validation dataset and provided a new way to predict the prognosis of pancreatic cancer patients.

A 50-year-old refugee woman with a lithopedion and a lifetime of trauma: a case report - BMC Women's HealthBackground Lithopedion is a term that refers to a fetus that has calcified or changed to bone. The calcification may involve the fetus, membranes, placenta, or any combination of these structures. It is an extremely rare complication of pregnancy and can remain asymptomatic or present with gastrointestinal and/or genitourinary symptoms. Case presentation A 50-year-old Congolese refugee with a nine-year history of retained fetus after a fetal demise was resettled to the United States (U.S.). She had chronic symptoms of abdominal pain and discomfort, dyspepsia, and gurgling sensation after eating. She experienced stigmatization from healthcare professionals in Tanzania at the time of the fetal demise and subsequently avoided healthcare interaction whenever possible. Upon arrival to the U.S., evaluation of her abdominal mass included abdominopelvic imaging which confirmed the diagnosis of lithopedion. She was referred to gynecologic oncology for surgical consultation given intermittent bowel obstruction from underlying abdominal mass. However, she declined intervention due to fear of surgery and elected for symptom monitoring. Unfortunately, she passed away due to severe malnutrition in the context of recurrent bowel obstruction due to the lithopedion and continued fear of seeking medical care. Conclusion This case demonstrated a rare medical phenomenon and the impact of medical distrust, poor health awareness, and limited access to healthcare among populations most likely to be affected by a lithopedion. This case highlighted the need for a community care model to bridge the gap between the healthcare team and newly resettled refugees.

Mediterranean diet adherence is associated with lower dementia risk, independent of genetic predisposition: findings from the UK Biobank prospective cohort study - BMC MedicineBackground The identification of effective dementia prevention strategies is a major public health priority, due to the enormous and growing societal cost of this condition. Consumption of a Mediterranean diet (MedDiet) has been proposed to reduce dementia risk. However, current evidence is inconclusive and is typically derived from small cohorts with limited dementia cases. Additionally, few studies have explored the interaction between diet and genetic risk of dementia. Methods We used Cox proportional hazard regression models to explore the associations between MedDiet adherence, defined using two different scores (Mediterranean Diet Adherence Screener [MEDAS] continuous and Mediterranean diet Pyramid [PYRAMID] scores), and incident all-cause dementia risk in 60,298 participants from UK Biobank, followed for an average 9.1 years. The interaction between diet and polygenic risk for dementia was also tested. Results Higher MedDiet adherence was associated with lower dementia risk (MEDAS continuous: HR = 0.77, 95% CI = 0.65–0.91; PYRAMID: HR = 0.86, 95% CI = 0.73–1.02 for highest versus lowest tertiles). There was no significant interaction between MedDiet adherence defined by the MEDAS continuous and PYRAMID scores and polygenic risk for dementia. Conclusions Higher adherence to a MedDiet was associated with lower dementia risk, independent of genetic risk, underlining the importance of diet in dementia prevention interventions.
