RESUMO
INTRODUCTION: Research studies tracking gender and academic publication productivity in healthcare find gender disparities in research activity, publication, and authorship. Article authorship is one of the important metrics to track when seeking to understand gender inequality in academic career advancement. Research on gender disparities in publication productivity in the field of Medical Radiation Science (MRS) is very limited thus this study analyses and explains potential gender differences in article authorship and acceptance for publication in the Journal of Medical Imaging and Radiation Sciences (JMIRS) for a 5-year period (2017-2021). METHODS: Gender was inferred based on the author's first name or title (e.g., Mr, Mrs or Ms). For those who left the title blank or reported as 'Dr' or 'Prof,' a series of steps were taken to identify their gender. Where gender was impossible to ascribe, these authors were excluded. Descriptive and inferential statistics are reported for the study population. Descriptive and inferential statistics are used. Percentages of females are reported, and males constitute the other portion. Chi-square, slope analysis and z-tests were used to test hypotheses. RESULTS: Results show that female authorship overall and in all categories of authorship placement (i.e., first, last and corresponding) increased over the timeframe reviewed. The percentage gain in the increase was higher than that for male authorship. However, male authorship started from a higher baseline in 2017 and has also increased year on year and overall, as well as in each placement category examined. More female authors were in the MRS sub-specialism Radiation Therapy (RT) than in the other MRS sub-specialisms. Analysis of the acceptance rate of articles with female authors shows a weak downward trend, and this may be related to higher submission and acceptance rates of articles by male authors during the same period. CONCLUSION: Male authors are overrepresented in all categories, which raises questions about the persistence of gender disparities in JMIRS authorship and article acceptance. Positive trends in female authorship indicate progress, yet there is the persistence of the significant under-representation of women in the Medical Radiation Sciences workforce in academic publishing. Recruiting more males to address the gender imbalance in the profession should not be at the expense of females' career progression.
RESUMO
Neurofibromatosis type 1 (NF1) is a human genetic disorder caused by variants in the NF1 gene. Plexiform neurofibromas, one of many NF1 manifestations, are benign peripheral nerve sheath tumors occurring in up to 50% of NF1 patients. A substantial fraction of NF1 pathogenetic variants are nonsense mutations, which result in the synthesis of truncated non-functional NF1 protein (neurofibromin). To date, no therapeutics have restored neurofibromin expression or addressed the consequences of this protein's absence in NF1 nonsense mutation patients, but nonsense suppression is a potential approach to the problem. Ataluren is a small molecule drug that has been shown to stimulate functional nonsense codon readthrough in several models of nonsense mutation diseases, as well as in Duchenne muscular dystrophy patients. To test ataluren's potential applicability in nonsense mutation NF1 patients, we evaluated its therapeutic effects using three treatment regimens in a previously established NF1 patient-derived (c.2041C > T; p.Arg681X) nonsense mutation mouse model. Collectively, our experiments indicate that: i) ataluren appeared to slow the growth of neurofibromas and alleviate some paralysis phenotypes, ii) female Nf1-nonsense mutation mice manifested more severe paralysis and neurofibroma phenotypes than male mice, iii) ataluren doses with apparent effectiveness were lower in female mice than in male mice, and iv) age factors also influenced ataluren's effectiveness.
RESUMO
BACKGROUND CONTEXT: The Oswestry Disability Index (ODI) is widely utilized as a patient reported outcome (PRO) tool to assess patients presenting with low back pain (LBP) and following thoracolumbar spine surgery. No primary study has calculated the baseline range of ODI values in the diverse American population. Establishing age-adjusted normative values for ODI in the American population is crucial for assessing the utility of treatment strategies. PURPOSE: The purpose of this study is to describe the baseline range of functional low back disability as measured by the ODI in an American population. STUDY DESIGN/SETTING: Cross-Sectional Observational Study. PATIENT SAMPLE: A total of 1214 participants were recruited from the United States in January 2024 using a combination of the Connect and PrimePanel platforms by CloudResearch to complete a survey administered on a RedCap online database. The survey consisted of 10 demographic questions and the 10 ODI survey questions. The distribution of the survey was designed to obtain approximately 100 respondents in each of the following age groups: 18-29, 30-39, 40-49, 50-59, 60-69, 70-79, and 80-89. The distribution of the sample was similarly designed to match the US Census racial data with 78.1% White, 13.9% Black, and 7.9% other. OUTCOME MEASURES: Oswestry Disability Index (ODI). METHODS: A crowd-sourcing platform called Cloudresearch was used to collect a representative sample of the US population by answering questions of the Oswestry Disability Questionnaire (ODQ), a 10-question survey. RESULTS: The final sample size was 797 participants including 386 (48.4%) males and 411 (51.6%) females; 169 participants were excluded that did not complete the survey and an additional 248 were excluded for failing attention check questions. The overall mean ODI score for the combined age groups was 14.35 (95% CI [13.33, 15.37]). The mean ODI scores increased with age, with the highest mean ODI in ages 70-79 at 18.0 (95% CI [14.76, 21.24]). Female participants reported higher mean ODI scores than their male counterparts in the 18-29 age group (Pâ¯=â¯.01), 50-59 age group (Pâ¯=â¯.01), and 60-69 age group (Pâ¯=â¯.02). Additionally, a weak positive correlation was found between Body Mass Index (BMI) and ODI scores (râ¯=â¯0.22, P < .001). CONCLUSION: Our findings demonstrate a clear trend of increased disability with age. This study describes the baseline range of functional low back pain disability in the US population. By defining these parameters, healthcare professionals can better tailor age and sex-specific interventions to manage disability in the aging U.S. population, ultimately improving patient care and both operative and non-operative treatment plans for LBP-related thoracolumbar pathology.
RESUMO
INTRODUCTION: There is evidence that sex differences exist in stroke presentation, risk factors, severity, treatment, and outcomes. To further understand this, we explored how sex differences influence acute stroke management, secondary prevention prescribing, and mortality outcomes in a well-characterised cohort of first-ever stroke patients in Scotland. METHODS: This is a retrospective, population-based, data-linkage study of stroke admissions to acute care hospitals in Scotland between January 1, 2011, and December 31, 2018. Data sources included the Scottish Stroke Care Audit (SSCA), the Prescribing Information System (PIS), the Scottish Morbidity Record 01 (SMR01), and the National Records of Scotland (NRS) death records. Multivariable logistic regression was used to explore the association between patient sex, acute stroke care, and secondary prevention prescribing, while Cox proportional hazards models were used to explore the association between patient sex and all-cause mortality up to 1 year after index event. RESULTS: This study included 5,901 patients with a first-ever intracerebral haemorrhage (ICH) and 47,087 patients with a first-ever acute ischaemic stroke (AIS). After an ICH, women had significantly lower odds of receiving all components of the stroke care bundle (adjusted odds ratio [aOR], 0.78; 95% confidence interval [CI], 0.69-0.87) and were less likely to be prescribed antihypertensives within 90 days after discharge to the usual place of residence (aOR, 0.78; 95% CI, 0.63-0.97). There was no sex difference in stroke care bundle achievement for those admitted with AIS; however, women had significantly lower odds of receiving antihypertensives, lipid-lowering drugs, or oral anticoagulants after discharge. The risk of all-cause mortality was lower in women at 1 year after both ICH (adjusted hazard ratio [aHR], 0.90; 95% CI, 0.83-0.98) and AIS (aHR, 0.91; 95% CI, 0.87-0.95) after adjusting for potential confounders. CONCLUSION: The sex differences in stroke treatment and outcomes may be partly explained by the older age of women at the time of stroke, which influences stroke presentation, severity, and prognosis. However, following adjustment, women had a reduced risk of all-cause mortality after both ICH and AIS.
RESUMO
OBJECTIVE: Our study examined the impact of sex, ADHD subtype, and comorbid illnesses (depression/anxiety) on the timing of diagnosis and treatment for ADHD. METHOD: To analyze ADHD patients, four health databases were used to assess subtype, comorbid mood, and antidepressant or anxiolytic drug exposure. Analyses were stratified by sex and age. Standardized mean differences measured intergroup differences. RESULTS: Females with ADHD were identified at older ages and had higher rates of depression and anxiety diagnoses and treatments before and after their initial ADHD diagnosis. Predominantly inattentive ADHD patients were diagnosed later and more likely to receive mood disorder diagnosis and treatment than hyperactive impulsive ADHD patients. CONCLUSIONS: Results suggest a more complex ADHD presentation in females, potentially causing late diagnosis and delayed treatment.

Background and Purpose: Each item in the instrumental activities of daily living (IADL) questionnaire has differential importance to an individual's life functioning based on gender. However, IADL has mostly been utilized for its total score alone, without gender specificity. We identify the impact of each item on the transition from amnestic mild cognitive impairment (aMCI) to Alzheimer's disease dementia (ADD), and determine if the impact of each item differs by gender. Methods: Subjects were aMCI or ADD with a global clinical dementia rating of 0.5 or 1. The sample size was 146 men and 154 women. We used logistic regression analysis to determine the effect of each item of IADL on the transition from aMCI to ADD. Results: The odds ratio (OR) for "remembering recent events" had similar values: 27.2 for men, and 27.7 for women. Gender difference was identified in the item with the highest OR value. For women, the "using transportation" item was 63.3, and for men, "conducting financial affairs" was overwhelmingly high at 89.1. Conclusions: Functional decline on items with relatively higher ORs may indicate higher probability of a transition from aMCI to ADD. The OR of "conducting financial affairs" was relatively higher for both genders. In terms of gender differences, "conducting home repair" for men, and "using transportation" for women, have relatively higher impact. This study demonstrates that during the transition from aMCI to ADD, each item of IADL shows a staggered decline in functioning, and that this decline is gender-specific.
RESUMO
BACKGROUND: Cardiac troponins are the preferred biomarkers for the diagnosis of acute myocardial infarction. Although sex-specific 99th percentile thresholds of troponins are recommended in international guidelines, the clinical effect of their use is poorly investigated. The DANSPOT Study (The Danish Study of Sex- and Population-Specific 99th percentile upper reference limits of Troponin) aims to evaluate the clinical effect of a prospective implementation of population- and sex-specific diagnostic thresholds of troponins into clinical practice. METHODS: This study is a nationwide, multicenter, stepped-wedge cluster-randomized trial of the implementation of population- and sex-specific thresholds of troponins in 22 of 23 clinical centers in Denmark. We established sex-specific thresholds for 5 different troponin assays based on troponin levels in a healthy Danish reference population. Centers will sequentially cross over from current uniform manufacturer-derived thresholds to the new population- and sex-specific thresholds. The primary cohort is defined as patients with symptoms suggestive of acute coronary syndrome having at least 1 troponin measurement performed within 24 hours of arrival with a peak troponin value between the current uniform threshold and the new sex-specific female and male thresholds. The study will compare the occurrence of the primary outcome, defined as a composite of nonfatal myocardial infarction, unplanned revascularization, and all-cause mortality within 1 year, separately for men and women before and after the implementation of the new sex-specific thresholds. CONCLUSIONS: The DANSPOT Study is expected to show the clinical effects on diagnostics, treatment, and clinical outcomes in patients with myocardial infarction of implementing sex-specific diagnostic thresholds for troponin based on a national Danish reference population.

OBJECTIVES: To evaluate the diagnostic performance of ultrasound guided attenuation parameter (UGAP) for evaluating liver fat content with different probe forces and body positions, in relation to sex, and compared with proton density fat fraction (PDFF). METHODS: We prospectively enrolled a metabolic dysfunction-associated steatotic liver disease (MASLD) cohort that underwent UGAP and PDFF in the autumn of 2022. Mean UGAP values were obtained in supine and 30° left decubitus body position with normal 4 N and increased 30 N probe force. The diagnostic performance was evaluated by the area under the receiver operating characteristic curve (AUC). RESULTS: Among 60 individuals (mean age 52.9 years, SD 12.9; 30 men), we found the best diagnostic performance with increased probe force in 30° left decubitus position (AUC 0.90; 95% CI 0.82-0.98) with a cut-off of 0.58 dB/cm/MHz. For men, the best performance was in supine (AUC 0.91; 95% CI 0.81-1.00) with a cut-off of 0.60 dB/cm/MHz, and for women, 30° left decubitus position (AUC 0.93; 95% CI 0.83-1.00), with a cut-off 0.56 dB/cm/MHz, and increased 30 N probe force for both genders. No difference was in the mean UGAP value when altering body position. UGAP showed good to excellent intra-reproducibility (Intra-class correlation 0.872; 95% CI 0.794-0.921). CONCLUSION: UGAP provides excellent diagnostic performance to detect liver fat content in metabolic dysfunction-associated steatotic liver diseases, with good to excellent intra-reproducibility. Regardless of sex, the highest diagnostic accuracy is achieved with increased probe force with men in supine and women in 30° left decubitus position, yielding different cut-offs. CLINICAL RELEVANCE STATEMENT: The ultrasound method ultrasound-guided attenuation parameter shows excellent diagnostic accuracy and performs with good to excellent reproducibility. There is a possibility to alter body position and increase probe pressure, and different performances for men and women should be considered for the highest accuracy. KEY POINTS: ⢠There is a possibility to alter body position when performing the ultrasound method ultrasound-guided attenuation parameter. ⢠Increase probe pressure for the highest accuracy. ⢠Different performances for men and women should be considered.
RESUMO
PURPOSE: Epidemiological TB data indicate differences in infection prevalence, progression rates, and clinical disease incidence between sexes. In contrast, evidence on sex-specific differential (post) TB case fatality in Europe has not been synthesized systematically. METHODS: We searched electronic databases and grey literature up to December 2020 for studies reporting sex-stratified TB death data for Europe. The JBI critical appraisal tools served for bias risk assessment and subgroup analyses for studying heterogeneity. Random-effects models meta-analyses enabled estimating pooled relative risks of sex-associated TB fatality. Considering associations of comorbidities and risk factors on fatality differences, we applied relative risk meta-regression. RESULTS: Based on 17,400 records screened, 117 studies entered quantitative analyses. Seventy-five studies providing absolute participant data with moderate quality and limited sex stratification reported 33 to 235,000 TB cases and 7 to 27,108 deaths. The pooled male-to-female TB fatality risk ratio was 1.4 [1.3-1.5]. Heterogeneity was high between studies and subgroups. Study time, concurrent comorbidities (e.g., HIV, diabetes, cancers), and mean participant ages showed no effect modification. We identified higher male TB fatality in studies with higher homelessness (coefficient 3.18, 95% CI [-0.59 to 6.94], p-value 0.10) and lower migrants proportion (coefficient - 0.24, 95% CI [- 0.5 to 0.04], p-value 0.09). CONCLUSION: We found 30-50% higher TB case fatality for males in Europe. Except for homelessness, migration, and a trend for some comorbidities, assessing effect modification could not reduce our meta-analysis' high heterogeneity. Public health authorities should take heed of this higher risk of dying in male patients' treatment services.
RESUMO
Futile recanalization hampers prognoses of ischemic stroke after successful mechanical thrombectomy, hypothetically through post-recanalization perfusion deficits, onset-to-groin delays and sex effects. Clinically, acute multiparametric imaging studies remain challenging. We assessed possible relationships between these factors and disease outcome after experimental cerebral ischemia-reperfusion, using translational MRI, behavioral testing and multi-model inference analyses. Male and female rats (N = 60) were subjected to 45-/90-min filament-induced transient middle cerebral artery occlusion. Diffusion, T2- and perfusion-weighted MRI at occlusion, 0.5 h and four days after recanalization, enabled tracking of tissue fate, and relative regional cerebral blood flow (rrCBF) and -volume (rrCBV). Lesion areas were parcellated into core, salvageable tissue and delayed injury, verified by histology. Recanalization resulted in acute-to-subacute lesion volume reductions, most apparently in females (n = 19). Hyperacute normo-to-hyperperfusion in the post-ischemic lesion augmented towards day four, particularly in males (n = 23). Tissue suffering delayed injury contained higher ratios of hypoperfused voxels early after recanalization. Regressed against acute-to-subacute lesion volume change, increased rrCBF associated with lesion growth, but increased rrCBV with lesion reduction. Similar relationships were detected for behavioral outcome. Post-ischemic hyperperfusion may develop differentially in males and females, and can be beneficial or detrimental to disease outcome, depending on which perfusion parameter is used as explanatory variable.

Objective:To investigate the clinical characteristics and drug resistance of Klebsiella pneumoniae infections at different systems, providing laboratory reference for the rational use of antibiotics in clinical practice.Methods:The clinical characteristics and drug resistance of patients with Klebsiella pneumoniae infections in respiratory, urinary, hematologic, and other systems who received treatment in Wuzhou Red Cross Hospital from January 2015 to December 2021 were analyzed.Results:From 2015 to 2021, there were 3 496 cases of Klebsiella pneumoniae infections in the hospital, among which the respiratory system was most affected with 2 250 strains (64.34%). The sex ratio of patients with Klebsiella pneumoniae infections at different systems was statistically significant ( χ2 = 266.77, P < 0.001). The respiratory system and hematological system were more commonly infected by Klebsiella pneumoniae in men, while the urinary system was more commonly infected in women. The sex ratio of patients with Klebsiella pneumoniae infections at other systems were similar. The age distribution of patients with Klebsiella pneumoniae infections at different systems was significantly different ( χ2 = 176.54, P < 0.001). Klebsiella pneumoniae infections of the respiratory, urinary, and hematological systems were the most common in people aged > 60-80 years, while Klebsiella pneumoniae infections in other systems were mainly found in people aged > 18-60 years. There were significant differences in the distribution of departments among different Klebsiella pneumoniae infection systems ( χ2 = 1 415.30, P < 0.001). The ICU had the highest incidence of Klebsiella pneumoniae infections in the respiratory system, while the department of internal medicine had the highest incidence of Klebsiella pneumoniae infections in the urinary and hematological systems, and the department of surgery had the highest incidence of Klebsiella pneumoniae infections in other parts of the body. The resistance rate of Klebsiella pneumoniae to common antibiotics for the hematologic system was lower than that of the other three infection systems. For infections in the respiratory system, urinary system, and other body parts, the resistance rates of Klebsiella pneumoniae to amikacin, meropenem, imipenem, and piperacillin/tazobactam were all below 10%, while the resistance rate to tobramycin was below 20%, and the resistance rate to cephalosporins was around 30%. Conclusion:The proportion of Klebsiella pneumoniae infections in different body parts varies by gender, age, and department. For Klebsiella pneumoniae infections in the hematological system, the resistance rate to commonly used antibiotics is lower than that for infections in the other three systems. In contrast, Klebsiella pneumoniae infections in the respiratory system, urinary system, and other systems have a particularly high resistance rate to third- and fourth-generation cephalosporins but are still sensitive to piperacillin/tazobactam and carbapenem antibiotics.
RESUMO
Objective:To investigate the influential factors of patients' expectations for clinical decision-making during digestive endoscopy.Methods:A total of 120 patients who underwent digestive endoscopy were admitted to the Endoscopy Center of Zhejiang Provincial People's Hospital from January 2020 to January 2022. Their general information was collected, and their clinical decision-making expectations were evaluated using the Control Preference Scale (CPS). The influential factors of clinical decision-making expectations were determined using multiple linear regression analysis.Results:The total CPS score for 120 patients undergoing digestive endoscopy was (50.72 ± 5.48) points, including (14.12 ± 1.48) points for information needs, (25.17 ± 3.52) points for communication needs, and (11.43 ± 2.04) points for decision-making needs. Univariate analysis showed that the CPS score of patients undergoing digestive endoscopy was related to gender, age, marital status, educational level, number of children, and type of visit ( t = 2.68, 2.61, 2.82, 3.28, 3.61, 2.39, all P < 0.05). Multiple linear regression analysis showed that gender, age, educational level, and type of visit were the influential factors of clinical decision-making expectations for patients undergoing digestive endoscopy ( β = -0.71, 1.07, 0.53, -1.15, all P < 0.05). Conclusion:Gender, age, educational level, and type of visit are influential factors of patients' expectations for clinical decision-making during digestive endoscopy. Patients have a clear need for communication during clinical decision-making, and medical staff can strengthen communication with patients, correctly guiding them to participate in clinical decision-making expectations.
RESUMO
Objective@#To explore sex difference in the cardiovascular health (CVH) status of 6-8 year old children in Beijing, so as to inform the early intervention of CVH related lifestyles.@*Methods@#Based on the Beijing Children s Growth and Health Cohort (PROC), baseline physical examination, sequential questionnaire survey, and laboratory tests were conducted among 1 914 grade 1 students. Children s CVH and its subscales (health behaviors and health factors) scores were calculated according to the Life s Essential 8 (LE 8) index and categorized into high, moderate, and low CVH. CVH scores were reported as medians and interquartile ranges; sex differences were compared using the Chi square test and Wilcoxon test.@*Results@#Among the 1 914 participants, the percentages of high, moderate, and low CVH were 35.7%, 63.5%, and 0.8%, respectively, and the percentages of high, moderate, and low health behavior scores were 25.9%, 67.5%, and 6.6%, respectively, with no statistically significant differences between sex ( χ 2=2.30, 0.07, P >0.05). The rates of high, moderate, and low health factor scores for boys and girls were 61.1%, 36.0%, 2.9% and 71.1%, 28.4%, 0.5%, respectively, with a statistically significant sex difference ( χ 2=31.88, P < 0.01). The overall CVH score was 76.0(70.0, 83.0), 76.0(69.0, 82.0) for boys, and 77.0(71.0, 83.0) for girls. Among the health behavior metrics, sleep scores were the best and physical activity scores were the worst[100.0(90.0,100.0), 40.0(20.0, 80.0 )]; among the health factor metrics, blood glucose scores were the best and lipid scores were the worst[100.0(100.0,100.0), 60.0(40.0,100.0)]. In respect to health factors, there were significant gender differences in body mass index, blood lipids, blood sugar, and blood pressure scores ( Z =-6.92, 3.01, -6.60, -2.30, <0.05), but there were no significant gender differences in diet, physical activity, nicotine exposure, or sleep scores with regards to health behaviors ( Z =0.99, 0.88, -0.13, 0.36, P > 0.05 ). Compared to boys, girls in the low and moderate CVH groups had high health factor scores despite low health behavior scores.@*Conclusion@#Most 6 to 8-year-old children in Beijing were found to have relatively good CVH, and optimization of children s CVH status can be achieved by promoting healthier lifestyles and monitoring health factors, especially among boys.
RESUMO
BACKGROUND: Symptom burden affects quality of life and prognosis in primary brain tumor (PBT) patients. Knowing whether symptom burden varies based on sex, race, or ethnicity may affect the interpretation of the relationship between symptoms and survival may reveal issues with applying the tools to measure symptom burden to different groups and may identify inequities in symptom management that need to be addressed at a system level. To determine whether symptoms in PBT patients vary across demographic groups, we conducted a retrospective chart review of symptom burden collected as part of routine care in a diverse population. METHODS: Patient demographics and scores on the MD Anderson Symptom Inventory-Brain Tumor (MDASI-BT) module were extracted from the electronic medical record for patients seen in the Inova Neuro-oncology Clinic between March 2021 and June 2022. MDASI-BT scores were compared based on side of tumor, sex, race, and ethnicity for the entire population and for the subset with gliomas. RESULTS: We included 125 people, of whom 85 had gliomas. For both the entire group and the subgroup with gliomas, about 40% were female and about 40% were non-White race. No differences in symptom burden were seen between males and females. Pain and numbness/tingling symptom burden were higher in both the entire population and the glioma subgroup for people of Hispanic/Latino/Spanish ethnicity and for people of races other than White or Middle Eastern self-identification. CONCLUSIONS: Pain, weakness, and numbness/tingling varied significantly across racial and ethnic groups. Further research is needed to validate this finding in other populations and determine its cause.
RESUMO
BACKGROUND: Because no data are available, we compared the 3-year outcomes of patients with non-ST-elevation myocardial infarction (NSTEMI) based on sex and symptom-to-balloon time (SBT). METHODS: This study included 4910 patients who were divided into two groups based on SBT: SBT <48 h (n = 3,293, 67.1%) and SBT ≥48 h (n = 1,617, 32.9%). The primary outcome was all-cause death during the 3-year follow-up period. The secondary outcome was major adverse cardiac events (MACE), defined as all-cause death, recurrent myocardial infarction, or repeat coronary revascularization. RESULTS: After adjustment, the in-hospital mortality rates for males and females in the SBT <48 h and SBT ≥48 h groups were similar. During a 3-year follow-up period, females in the SBT <48 h group had significantly higher rates of all-cause death (adjusted hazard ratio [aHR], 1.482; P = 0.006), cardiac death (CD, aHR, 1.617; P = 0.009), and MACE (aHR, 1.268; P = 0.024) than those males in the same groups. Females and males in the SBT ≥48 h group did not differ significantly in the primary and secondary outcomes. In males, the rates of all-cause death (P = 0.008) and CD (P = 0.024) were significantly higher in the SBT ≥48 h group than in the SBT <48 h group. CONCLUSIONS: This study has identified a higher 3-year mortality rate in female patients with NSTEMI and SBT <48 h compared to their male counterparts. As such, a more preventive approach may be required to reduce mortality in these female patients.
RESUMO
Introduction: Bilingualism has historically been claimed to be a risk factor for developmental stuttering. The Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011) ostensibly contains evidence to test that claim. Methods: We analyze data from monolingual and bilingual children in Kindergarten through fifth grade in the ECLS-K:2011. Results and discussion: The prevalence, male/female ratio, and onset and recovery of reported stuttering in the ECLS are inconsistent with widely-accepted clinical reports of stuttering. We argue that the reported figures may be misleading. We discuss some factors that may inflate the reported prevalence, including a lack of awareness of the difference between stuttering vs. normal disfluencies, and the informal usage of the word "stuttering" on the part of teachers and parents to describe typical disfluencies.
RESUMO
INTRODUCTION: A knowledge gap exists in the relationship between suicide and psychiatric hospitalization in Asia. This study investigated inpatient service utilization before suicide and suicide risk at different periods of hospitalization in Taiwan. METHODS: Using the National Health Insurance Research Database, we applied a nested case-control design with controls being alive on the date each case died by suicide. RESULTS: A total of 56 939 suicide cases and 1 138 780 controls were included (2:1 male-to-female ratio). Only 5.7% of suicide cases had a history of psychiatric hospitalization in the preceding year. Patients with a history of psychiatric hospitalization were associated with a higher risk of inpatient and postdischarge suicide than those without prior hospitalization. The risk was greatest in the first postdischarge week, decreased gradually, and remained significantly elevated over 7 years after discharge. The suicide risk increased more in females. Patients with affective disorders had higher inpatient and postdischarge suicide risks than those with schizophrenia spectrum disorders. DISCUSSION: A low rate of psychiatric hospitalization before suicide implies that inpatient treatment of psychiatric disorders could be enhanced. Community-based approaches to suicide prevention can improve the treatment utilization of those with suicide risk and bridge continuous care from hospital to community.

OBJECTIVE: Research investigating cannabis use and sleep health is limited, and results are mixed. Few studies were nationally representative with racially-ethnically diverse samples or assessed potential modifiers. Our objective was to investigate cross-sectional associations between reported cannabis use and sleep disturbances by potential modifiers among non-Hispanic White, non-Hispanic Black, and Hispanic/Latino men and women in the United States. METHODS: We used nationally representative National Comorbidity Survey-Replication data collected from 2001 to 2003 among 3929 adults. Poisson regression with robust variance estimated prevalence ratios (PR) and 95% confidence intervals of patterns of sleep disturbances identified through latent class analysis. Models adjusted for sociodemographic, health behavior, and clinical characteristics were stratified by race-ethnicity and by race-ethnicity along with sex/gender, and age, separately. RESULTS: Over half of adults reported cannabis use (52%-ever/lifetime vs 48%-never). We identified two latent classes: multiple sleep disturbances with daytime sleepiness and no sleep disturbances with some daytime sleepiness. Prevalence of multiple sleep disturbances with daytime sleepiness was higher among participants reporting lifetime cannabis use (23% vs 20%). Associations did not vary by race-ethnicity or sex/gender. Lifetime vs never cannabis use was marginally associated with a higher prevalence of multiple sleep disturbances with daytime sleepiness only among adults aged 25-29years (PR=1.09 [95% confidence interval: 1.00-1.18]; eg, PRage 40+ years=1.00 [0.97-1.03], pinteraction=0.03). CONCLUSIONS: Associations between cannabis use and sleep may vary by age. Replication with more recent data and prospective studies that investigate intersectional identities among diverse populations with objective assessments are warranted.
RESUMO
Objectives: To investigate the effect of gender on the activation ratio of vastus medialis oblique to vastus lateralis during straight leg raising and stepdown activities. Method: The cross-sectionalstudy was conducted at the College of Medical Rehabilitation Sciences, Taibah University, Medina, Kingdom of Saudi Arabia, from September 2021 to March 2022, and comprised recreationally active subjects without knee pathology who were distributed in 2 gender-based groups. All the participants were subjected to straight leg raising and stepdown activitiesthrice and the average value of each activity was noted. The vastus medialis oblique and vastus lateralis electromyographic activity of the dominant limb was recorded using surface electromyography during the activities. The normalised value of the activation ratio of vastus medialis oblique to vastus lateralis levels was calculated. Data was analysed using SPSS 25. RESULTS: Of the 60 subjects, there were 30(50%) males with mean age 30.00±5.91 years, mean height 167±5.63cm, mean body weight 66.76±6.14kg, and mean body mass index 23.97±3.02kg/m2 . There were 30(50%) females with mean age 29.03±5.34 years, mean height 186±6.20cm, mean body weight 68.5±5.6 kg and mean body mass index 23.76±3.22 kg/m2 . There was no significant difference in the normalized electromyography activities of the vastus medialis oblique and vastuslateralis muscles between males and females(p>0.05). Also, no significant difference was found in the activation ratio between the genders (p>0.05). CONCLUSIONS: There were no gender-based differencesin the activation ratio of vastus medialis oblique to vastuslateralis during weight-bearing and non-weight-bearing activities.

Oxytocin and vasopressin share a similar chemical structure but have different functions. Both hormones are produced in different brain areas, are transported through the hypophyseal portal system, pass to the anterior hypophysis, and released to reach their target organs. These hormones also act as neuromodulators, where its receptors are found in the lateral septum, the middle amygdala, the hippocampus, the hypothalamus, and the brain stem. These brain structures regulate socio-sexual behaviors in vertebrates. Moreover, the oxytocinergic and the vasopressin systems are sexually different. The sexual steroids promote oxytocin release and the oxytocin receptor synthesis, as well as promoting or inhibiting vasopressin release and its receptor genetic transcription. Both neuropeptides are involved in social recognition, male-female pair bonding, aggression, and cognition. Furthermore, the disruption or malfunctioning of the oxytocin and vasopressin systems adds to the causes of some psychiatric disorders like depression, schizophrenia, autism, and borderline personality.
La oxitocina y la vasopresina son similares en estructura química, pero difieren en sus funciones. Ambas se producen en diversas áreas del cerebro, se transportan a través del sistema porta hipofisario a la hipófisis anterior y se distribuyen a sus órganos blanco actuando como hormonas. Estas fungen también como neurorreguladores, con receptores dispersos en el septum lateral, la amígdala central, el hipocampo, el hipotálamo y el tronco encefálico, estructuras asociadas a la conducta sociosexual en todos los vertebrados. Los sistemas vasopresinérgico y oxitocinérgico difieren entre los cerebros femenino y masculino. Aunado a esto, los esteroides sexuales intervienen en la expresión de los genes para oxitocina, la síntesis de sus receptores y su liberación. Además, promueven o inhiben la transcripción de los genes para vasopresina. Ambos neuropéptidos participan en el reconocimiento social, el vínculo de pareja, la cognición y la agresión. La disrupción de los sistemas de estos neuromoduladores se suma a las causas de algunos desórdenes psiquiátricos, como la depresión, la esquizofrenia, el autismo y la personalidad limítrofe. Esta revisión está enfocada a describir las diferencias entre géneros, tanto de la síntesis, como la distribución de los receptores y los efectos que generan la oxitocina y la vasopresina en la conducta para comprender la prevalencia, la sintomatología y la respuesta a los tratamientos a dichas patologías.
