Gender-specific differences in haemostatic parameters and their influence on blood loss in bimaxillary surgery

Objective The objectives of this prospective cohort study were to establish gender-related differences in blood loss and haemostatic profiles associated with bimaxillary surgery. In addition, we aimed to identify if any gender differences could be established which might help predict blood loss volume. Materials and methods Fifty-four patients (22 males; 32 females) undergoing bimaxillary surgery for skeletal dentofacial deformities were eligible for inclusion. Blood samples were taken 1 day preoperatively and 48 h postoperatively for detailed gender-specific coagulation analysis incorporating global coagulation assays (endogenous thrombin potential) and specific coagulation parameters. Blood loss was measured at two different time points: (1) the end of surgery, visible intraoperative blood loss (IOB) using ‘subtraction method’; and (2) 48 h postoperatively perioperative bleeding volume (CBL-48 h) using ‘haemoglobin-balance method’ and Nadler’s formula. Correlation and regression analyses were performed to identify relevant parameters affecting the amount of blood loss. Results Significant differences in IOB and CBL-48 h were observed (p < 0.001). Men had higher IOB versus women, lacking statistical significance (p = 0.056). In contrast, men had significantly higher CLB-48 h (p = 0.019). Reduced CBL-48 h was shown to be most closely associated with the level of Antithrombin-III being decreased in females. Conclusions Male gender is associated with higher IOB and CBL-48 compared with females. Gender does not affect IOB regarding haemostatic profile but does correlate strongly with procedure length. Conversely, CBL-48 is closely associated with gender-specific imbalances in the anticoagulant system. Clinical relevance Knowledge of gender-related differences will help clinicians establish predictive factors regarding excessive blood loss in orthognathic surgery and identify at-risk patients.

Psychiatric Morbidity in Elderly Patients attending OPD of Lumbini Medical College and Teaching Hospital

INTRODUCTION: Geriatric psychiatry patients are increasing but enough work has not been done in this area of Nepal. We conducted this study to find out the prevalence of different psychiatric morbidities in elderly population and to find out if there are any age and gender specific differences. MATERIAL AND METHODS: Medical records of psychiatric patients above 65 years of age visiting outpatient department of Lumbini Medical College and Teaching Hospitalfrom April 1, 2018 to March 31, 2019 were reviewed. Risks of having different psychiatric disorders was estimated using odds ratio. RESULTS: A total of 300 cases were enrolled in the study. Mean age of the study group was 71.49(SD=6.99). There were more females. Depressive disorderwas the most common diagnosis followed by somatoform disorder, anxiety disorder, dementia and others. Depressive disorder was higher in females and in younger subgroup of the elderly patient.The risk of having dementia was higher in older group. CONCLUSION: Depressive disorder was the most common psychiatric disorderfollowed by somatoform disorder in elderly patients above 65 years of age. Male patients were more likely to suffer psychiatric disorder as compared to females in this age.

Gender-Specific Differences in Self-Care, Treatment-Related Symptoms, and Quality of Life in Hemodialysis Patients

Gender and sex differences affect women with kidney failure (KF) negatively at all stages of the disease. This study assessed gender differences in self-care, hemodialysis symptoms, and quality of life in a sample of 102 adult KF patients treated with hemodialysis, from two clinical centers in Mexico. Self-care agency, quality of life, and the symptoms related to hemodialysis were evaluated through questionnaires, and sociodemographic and laboratory variables were obtained from the clinical records. Compared to male patients, female patients reported similar self-care, lower quality of life subscales (symptoms, physical functioning, pain, and overall health), and higher prevalence and intensity of hemodialysis symptoms. There were gender differences regarding the correlation between self-care and quality of life, symptoms intensity, and symptoms prevalence. In conclusion, women with KF treated with hemodialysis perceived a higher impact of hemodialysis and reported a lower quality of life than men. Despite having a similar self-care agency, the self-care correlations with quality of life and hemodialysis symptoms appeared different between men and women treated with chronic hemodialysis. Such differences may be important in future nursing interventions to improve self-care and quality of life among KF patients.

Jointly Modeling Male and Female Labor Participation and Unemployment

The COVID-19 pandemic resulted in the most abrupt changes in U.S. labor force participation and unemployment since the Second World War, with different consequences for men and women. This paper models the U.S. labor market to help to interpret the pandemic’s effects. After replicating and extending Emerson’s (2011) model of the labor market, we formulate a joint model of male and female unemployment and labor force participation rates for 1980–2019 and use it to forecast into the pandemic to understand the pandemic’s labor market consequences. Gender-specific differences were particularly large at the pandemic’s outset; lower labor force participation persists.

Gender-Specific Differences of Renal Heat Tolerance in Older Adults during Heat Waves

<b><i>Background:</i></b> Heat waves are known to cause increased morbidity and mortality in susceptible populations like old and functionally impaired people. The objective of the study was to assess renal tubular stress, a predictor for development of acute kidney injury, during heat waves in Central Europe. As a marker of renal tubular stress tissue inhibitor of metalloproteinases-2 [TIMP-2]·insulin-like growth factor binding protein-7 [IGFBP7], a new FDA-cleared renal tubular stress biomarker, was used. <b><i>Materials and Methods:</i></b> 68 residents from facilities of sheltered housing with urine samples collected at heat waves in 2015 and at control visits were included. Urinary [TIMP-2]·[IGFBP7] was compared between the heat waves and the control visits. Multivariate linear models were adjusted for age, frailty index, and functional comorbidity index. <b><i>Results:</i></b> The median age was 82.0 years, 82.3% were women. The percentage of elevated levels of urinary [TIMP-2]·[IGFBP7] (&#x3e;0.3 [ng/mL]²/1,000) in the total study population was higher at the heat waves than at the control visits (25.0% vs. 17.7%). The effect of the heat waves on urinary [TIMP-2]·[IGFBP7] was stronger in men than in women: The percentage of elevated levels was 75.0% in men and 14.3% in women. In the multivariate analysis, the mean urinary [TIMP-2]·[IGFBP7] was 0.48 (95% CI 0.25; 0.70) (ng/mL)²/1,000 higher in men than in women. Except gender, a number of additional variables did not show an association with urinary [TIMP-2]·[IGFBP7] at the heat waves or the control visits. <b><i>Conclusions:</i></b> At heat waves, urinary [TIMP-2]·[IGFBP7] was elevated and higher in men than in women. This suggests gender-specific differences in renal heat tolerance in older people.

Gender-specific differences in patients who underwent left atrial appendage closure

Aim: We aimed to study gender-specific differences in patients who underwent left atrial appendage closure (LAAC). Materials & methods: A total of 201 consecutive patients who underwent LAAC were enrolled. The EQ-5D-3L questionnaire was employed before and 3 months post-LAAC to study the quality of life. Results: Women had a higher score for Anxiety/Depression before implantation. Three months after LAAC, both groups showed a significant improvement in mobility, self-care and usual activities. The female gender had a significant improvement in health state 3 months after implantation than their male counterparts. Conclusion: Our data shows an improvement in mobility, self-care, usual activities and the overall health state in all patients after LAAC. This potential improvement, most likely caused by the discontinuation of oral anticoagulants, should be considered an indication for LAAC.

Family and Developmental History of Female Versus Male Adolescents With ADHD: Disorder-specific Overlap but Few Gender Differences

Background: Gender differences in the development of children and adolescents are well known in the psychiatric examination including the clinical diagnostic interview technique. Some gender-specific differences in behaviors of patients as assessed in the clinical examination are related to typical development and some are related to disorders. Family and developmental history is an important part of the clinical diagnostic interview. Attention-deficit/hyperactivity disorder (ADHD) is associated with disorder-specific markers in family and development history. However, it is unclear to what extent ADHD-specific signs and narratives differ between female and male adolescents. The aim of this study was to assess and to compare the family and developmental history profiles of female versus male adolescents with ADHD.Methods: Data were collected using the clinical diagnostic interview technique from parents of female and male patients diagnosed with ADHD (ICD-10 F90.0, F90.1 and F98.8) between the ages of 12 and 17 years (n = 92). The two groups were matched in pairs for gender, IQ and ICD-10 diagnosis (F90.0, F90.1 and F98.8). The majority of interview data were non-metric and operationalized in three categories: 0 - normal behavior, 1 - minor pathological behavior, 2 - major pathological behavior. The two groups were compared with two-way ANOVA. Results: Female in comparison to male adolescents were reported by the parents with very few differences in items that are typical for ADHD. However, there were a few differences in items in which gender-specific differences are known regardless of ADHD. Conclusions: Our study suggests that ADHD-related items in family and developmental history, as obtained with the clinical diagnostic interview technique, appear in female compared to male adolescents more similar than different.

Gender and the Sex Hormone Estradiol Affect Multiple Sclerosis Risk Gene Expression in Epstein-Barr Virus-Infected B Cells

Multiple Sclerosis (MS) is a complex immune-mediated disease of the central nervous system. Treatment is based on immunomodulation, including specifically targeting B cells. B cells are the main host for the Epstein-Barr Virus (EBV), which has been described as necessary for MS development. Over 200 genetic loci have been identified as increasing susceptibility to MS. Many MS risk genes have altered expression in EBV infected B cells, dependent on the risk genotype, and are themselves regulated by the EBV transcription factor EBNA2. Females are 2-3 times more likely to develop MS than males. We investigated if MS risk loci might mediate the gender imbalance in MS. From a large public dataset, we identified gender-specific associations with EBV traits, and MS risk SNP/gene pairs with gender differences in their associations with gene expression. Some of these genes also showed gender differences in correlation of gene expression level with Estrogen Receptor 2. To test if estrogens may drive these gender specific differences, we cultured EBV infected B cells (lymphoblastoid cell lines, LCLs), in medium depleted of serum to remove the effects of sex hormones as well as the estrogenic effect of phenol red, and then supplemented with estrogen (100 nM estradiol). Estradiol treatment altered MS risk gene expression, LCL proliferation rate, EBV DNA copy number and EBNA2 expression in a sex-dependent manner. Together, these data indicate that there are estrogen-mediated gender-specific differences in MS risk gene expression and EBV functions. This may in turn contribute to gender differences in host response to EBV and to MS susceptibility.
