Gender differences in severity and parental estimation of adolescent’s pandemic-related stress in the United States

Research has consistently shown that female adolescents have experienced worse pandemic-related stress compared to males. A parent’s ability to accurately track their child’s stress levels likely increases the likelihood a problem is acknowledged and addressed as it arises. Therefore, we assessed how parents’ estimation of their adolescent children’s self-reported pandemic-related stress related to the child’s gender. We performed cross-sectional secondary analysis using the nationally representative Population Assessment of Tobacco and Health study datasets from Wave 5 (2018–2019) and Wave 5.5 (July 2020-December 2020) among respondents aged 12–17. We conducted four logistic regression models to explore the relationship between child gender and parental underestimation of their child’s pandemic-related stress. We controlled for sociodemographic factors and personal characteristics associated with pandemic-related stress including, whether the adolescent had been diagnosed with COVID-19, the extent social distancing measures were practiced, school performance, previous year anxiety, depression, and overall mental health ratings, sleep trouble, TV screen time, and past year substance use. Even when controlling for these factors, female child gender was significantly and positively associated with parental underestimation of their child’s pandemic-related stress (Underestimated stress: OR = 1.25 95% CI = [1.07–1.46]). Informing parents that female adolescents were significantly more likely to have their levels of pandemic-related stress underestimated at home may encourage parents to take extra effort when checking in on their daughters’ mental health needs, which in turn may lead to more female adolescents receiving the familial and professional support they require.

Pay Attention to Hypogonadism in Male Patients with COVID-19-A Review

Although there were significant gender differences in severity and mortality of COVID-19, most of the young male patients of childbearing age survived Studies

CFTR deletion affects mouse osteoblasts in a gender‐specific manner

Advancements in research and care have contributed to increase life expectancy of individuals with cystic fibrosis (CF). With increasing age comes a greater likelihood of developing CF bone disease, a comorbidity characterized by a low bone mass and impaired bone quality, which displays gender differences in severity. However, pathophysiological mechanisms underlying this gender difference have never been thoroughly investigated. We used bone marrow-derived osteoblasts and osteoclasts from Cftr+/+ and Cftr-/- mice to examine whether the impact of CF transmembrane conductance regulator (CFTR) deletion on cellular differentiation and functions differed between genders. To determine whether in vitro findings translated into in vivo observations, we used imaging techniques and three-point bending testing. In vitro studies revealed no osteoclast-autonomous defect but impairment of osteoblast differentiation and functions and aberrant responses to various stimuli in cells isolated from Cftr-/- females only. Compared with wild-type controls, knockout mice exhibited a trabecular osteopenic phenotype that was more pronounced in Cftr-/- males than Cftr-/- females. Bone strength was reduced to a similar extent in knockout mice of both genders. In conclusion, we find a trabecular bone phenotype in Cftr-/- mice that was slightly more pronounced in males than females, which is reminiscent of the situation found in patients. However, at the osteoblast level, the pathophysiological mechanisms underlying this phenotype differ between males and females, which may underlie gender differences in the way bone marrow-derived osteoblasts behave in absence of CFTR.

SUN-155 Clinical Experience of SGLT2 Inhibitors in a Hispanic Population: Should We Consider Its Use as Add-On Treatment?

Introduction: 1 in 11 adults have DM globally,1 and Hispanics have higher complication rates.2 A study determined that ~$16,750/year are spent by patients in medical related costs, of which ~$9,600 are related to diabetes.3 Half of Type 2 Diabetes Mellitus (T2DM) patients aren't achieving HbA1C targets,4 uncovering the need for treatment intensification. The primary purpose of this study was to assess the mean reduction in HbA1C between T2DM patients treated with SGLT2 inhibitors (SGLT2I) as adjunct therapy versus patients using other treatments not including SGLT2I. METHOD: T2DM patients with HbA1C > 7 (n=130) were selected for this retrospective cohort study; 69 SGLT2I users and 61 SGLT2I non-users. Medical records were reviewed and demographics, treatment received, HbA1C and side effects were evaluated during a 6-month follow-up period. RESULTS: The average baseline HbA1C for patients using vs not using SGLT2I as add-on was similar with a mean difference of 0.225 [CI -0.41-0.86], p<0.486. The mean difference in HbA1C at 6 months follow-up between both groups was -1.06 [95%CI: -1.70, -0.42], p<0.001. Adjusting for confounders resulted in a regression coefficient of -1.07 [95%CI: -1.85, -0.29], p<0.008, the null hypothesis was rejected and it was concluded that the use of SGLT2I is responsible for the increased HbA1C in the treatment group. CONCLUSION: Puerto Rico is under an economic crisis that affects patients treatment warranted by the availability of some medications due to affordability as supported by Roglic et al.5 The present study depicts a higher A1C reduction in patients using SGLT2 inhibitors as adjunctive treatment. But should we consider it as add-on treatment of T2DM? We may say that if patients are able to bear the expense of SGLT2I and/or are close to target it may be used as adjunctive treatment since the mean difference in A1C between both groups was -1.07 at 6 months. Limitations were the short follow up duration and a small population using SGLT2I due to high medication costs. REFERENCES: 1. Zheng Y, et al.

Large prospective study on adult acne in Latin America and the Iberian Peninsula: risk factors, demographics, and clinical characteristics.

Acne vulgaris is a chronic, multifactorial inflammatory skin disease involving the pilosebaceous unit. The prevalence of acne is high during adolescence and is known to persist into adulthood; however, the characteristics of adult acne have not been well established. In the adult population, acne has been associated with psychosocial repercussions impacting the quality of life of those who suffer it, especially in female patients. This study assessed the demographic and clinical characteristics of 1,384 patients between the ages of 25 and 60 years from 21 countries in Latin America and the Iberian Peninsula, with the purpose of identifying parameters for the severity of the disease, its links to demographic, biological, social, and environmental factors, and potential triggers. Gender differences in severity and location of the lesions were identified. In a univariate analysis, the male gender, use of cosmetics, age of onset of adolescence, and signs of hyperandrogenism were associated with acne severity. The characteristics of adult acne may vary from those of adolescent acne, although the disease presentations are generally similar. Further research is needed to establish similarities and differences in manifestations of adult acne versus adolescent acne.

Interleukin-6 and leptin levels are associated with preoperative pain severity in patients with osteoarthritis but not with acute pain after total knee arthroplasty

BackgroundIdentifying drivers of pain that can serve as novel drug targets is important for improving perioperative analgesia. Total knee arthroplasty (TKA) is associated with significant postoperative pain. Cytokines contribute to the pathophysiology of osteoarthritis (OA) and associated pain. However, the influence of perioperative cytokine levels after TKA surgery upon postoperative pain remains unexplored. MethodsWe designed a prospective observational study to profile three proinflammatory cytokines, interleukin-6 (IL-6), tumor necrosis factor α (TNFα), and leptin in serum, synovial, and cerebrospinal fluid of TKA patients perioperatively to determine associations between cytokine levels and pain. We characterized time-trajectories in cytokines pre- and post-surgery and explored their relationships to pain across gender. ResultsPreoperative pain, measured by functional pain disability scores (PDQ), was predictive of postoperative pain. There were no gender differences in severity of preoperative pain or acute postoperative pain. Serum IL-6, serum leptin, and synovial fluid leptin were positively correlated with body mass index and preoperative pain severity. Stratification of patients by gender revealed strong correlations between serum IL-6, leptin, and PDQ only in females, suggesting that females may be more sensitive to the nociceptive actions of these cytokines. Although serum IL-6 increased dramatically (and TNFα increased modestly) four hours after surgery and remained elevated at 72h; they were not associated with the severity of acute postoperative pain. ConclusionsOur data suggest that while preoperative chronic pain is predictive of the severity of acute postoperative pain in TKA patients, the pre- and post-operative inflammatory status does not predict postoperative pain.

Gender differences in severity of desaturation events following hypopnea and obstructive apnea events in adults during sleep

Objective: Severity estimation of obstructive sleep apnea (OSA) is currently based on the apnea–hypopnea index (AHI), which ignores individual breathing cessation event characteristics. Gender differences in the relationship between the breathing cessation event duration and the related desaturation event severity could mean that the severity of OSA is different in males and females despite a similar AHI. The aim of this work was to evaluate gender differences in the severity of peripheral oxygen desaturation events following obstructive apneas or hypopneas. Approach: Type I polysomnographic recordings of 220 males and 175 females were analyzed. The obstructive apnea and hypopnea events were divided into eight different durational categories from 10 s to 45 s with 5 s interval and >45 s. The desaturation event severities following obstructive apneas or hypopneas were compared between genders within these durational categories. Main results: Desaturations following obstructive apneas with a duration of 30–45 s were substantially more severe (p < 0.05) in females compared to males. In contrast, areas of desaturations following hypopneas (with related hypopnea event durations ⩽30 s) were smaller (p < 0.05) in females compared to males. In general, desaturation events following obstructive apneas were more severe compared to desaturations following hypopneas and the increase in the duration of obstructive apnea and hypopnea events led to an increase in the related desaturation severity in both genders. Significance: We found gender differences in the desaturation event severities following obstructive apneas and hypopneas. The results indicate that in females longer obstructive apneas (>30 s) could be more detrimental compared to those of males. As severe health consequences are related to the desaturation severity these aspects should be considered when estimating the severity of OSA.

Undiagnosed hypertension in a rural district in Bangladesh: The Bangladesh Population-based Diabetes and Eye Study (BPDES).

Hypertension is mainly asymptomatic and remains undiagnosed until the disease progresses. The objective of the study was to determine the prevalence of and risk factors for hypertension in rural Bangladesh. Using a population-based cluster random sampling strategy, 3096 adults aged ⩾30 years were recruited from a rural district in Bangladesh. Data collected included two blood pressure (BP) measurements, fasting blood glucose, socio-demographic and anthropometric measurements. Hypertension was defined as systolic BP (SBP) ⩾140 mm Hg or diastolic BP (DBP) ⩾90 mm Hg or self-reported diagnosed hypertension. Logistic regression techniques were used for data analyses. The crude prevalence of hypertension was 40% (95% confidence interval (CI) 38-42%) of which 82% were previously undiagnosed. People from lower socio-economic status (SES) had a significantly higher percentage of undiagnosed hypertension compared with people with higher SES (P<0.001). There was no significant gender difference in severity of hypertension. Males with higher education level compared with no education had a higher prevalence of hypertension (odds ratio 2.34, 95% CI 1.49-3.69). Older age and waist circumference in both genders, and diabetes, lack of physical activity in females were found to be associated with higher prevalence of hypertension. Our research suggests the prevalence of undiagnosed hypertension was higher in the rural area in Bangladesh than that reported from the rural area in neighbouring India and China. Lower SES was associated with a higher risk of undiagnosed hypertension. Public health programs at the grass-roots level must emphasise the provision of primary care and preventive services in managing this non-communicable disease.

Bladder and Bowel Dysfunction Is Common in Both Men and Women with Mutation of the ABCD1 Gene for X-Linked Adrenoleukodystrophy.

X-linked adrenoleukodystrophy (X-ALD) is a disorder caused by mutations in the ABCD1 gene. The commonest phenotype of X-ALD is adrenomyeloneuropathy (AMN), which is characterised by involvement of the spinal cord and peripheral nerves. The aim of this study was to evaluate bladder and bowel symptoms in men with AMN and female X-ALD carriers. In this cross-sectional study, patients with confirmed mutation of the ABCD1 gene attending a tertiary care service were approached about bladder and bowel complaints and completed the Urinary Symptom Profile (USP), Qualiveen Short Form (SF-Qualiveen), International Prostate Symptom Score (IPSS) and Neurogenic Bowel Dysfunction (NBD) questionnaires. Neurological disability was assessed using the Expanded Disability Status Scale (EDSS). Forty-eight patients participated, 19 males (mean EDSS score (n = 16) 5.0 (95% CI ± 1.03)) and 29 females (mean EDSS score (n = 25) 3.2 (95% CI ± 0.98)). Overactive bladder (OAB) symptoms were reported in both males (100%, n = 19) and females (86.2%, n = 25). There was no significant gender difference in severity of OAB symptoms (P = 0.35) and impact on quality of life (P = 0.13). Furthermore, there was no significant difference in OAB severity when symptoms were compared between female carriers and a cohort of women (n = 17) with spinal cord damage due to multiple sclerosis (P = 0.27). Twenty-one percent (n = 4) of males and 10% (n = 3) of females had moderate to severe bowel dysfunction. Bladder and bowel complaints are common in both men with AMN and female carriers. They have a significant impact on the quality of life yet are under-reported and under-treated. Though having an X-linked pattern of inheritance, female carriers may experience overactive bladder symptoms which are as severe as in male patients and are likely to be neurological in origin.

Racial/ethnic and gender differences in severity of diabetes-related complications, health care resource use, and costs in a Medicare population.

This retrospective cohort study evaluated associations of race/ethnicity and gender with outcomes of diabetes complications severity, health care resource utilization (HRU), and costs among Medicare Advantage health plan members with type 2 diabetes (T2DM). Medical and pharmacy claims were evaluated for 333,576 members continuously enrolled from January 1, 2010, to December 31, 2011, aged 18-89 years, with ≥1 primary diagnosis medical claim, or ≥2 claims with a secondary diagnosis of T2DM (International Classification of Diseases, Ninth Revision, Clinical Modification code 250.x0 or 250.x2). Complications severity assessment by Diabetes Complications Severity Index ranged from 0 (no complications) to 5+. Mean (SD) all-cause medical, pharmacy, and total costs were reported alongside all-cause HRU by place of service (outpatient, inpatient, emergency room [ER]) and number of visits. Multivariate regression showed being Hispanic, black, or male was associated with higher prevalence of more severe complications. This racial/ethnic disparity was more pronounced among females, among whom odds of having more severe complications were higher for Hispanic and black as compared to white females [(Hispanic vs. white odds ratio [OR], 1.40; 95% confidence interval [CI], 1.32-1.48), and (black vs. white OR, 1.22; 95% CI, 1.19-1.25)]. Regardless of gender, blacks had more ER visits than whites. White females incurred the highest total health care costs (mean annual costs: $13,086; 95% CI, $12,935-$13,240, vs. Hispanic females: $10,732; 95% CI, $10,406-$11,067). These effects held regardless of other demographic and clinical attributes. These findings suggest racial/ethnic and gender differences exist in certain T2DM clinical and economic outcomes.

Gender Differences in Severity and Correlates of Depression Symptoms in People Living with HIV in Ontario, Canada.

This study investigates the differences in severity and correlates of depression symptoms among 1069 men and 267 women living with HIV in Ontario, Canada, who completed the 20-item Center for Epidemiologic Studies Depression Scale (CES-D). Women had higher CES-D scores than that of men (median [interquartile range]: 13 [5-26] versus 9 [3-20], P=.0004). More women had total CES-D scores>15 (mild-moderate depression; 44% versus 33%, P=.002) and >21 (severe depression; 31% versus 23%, P=.003). Unlike men, at age 40, women's scores increased yearly (0.4 per increased year, P=.005). The distribution of scores differed by gender: There was no difference in the 10th percentile of depression scores, 0 (95% confidence interval [CI]: 1.0-1.0) but the 75th percentile of depression scores for women was 6 (95% CI: 2.0-10.0) points higher than that of men. Important gender differences exist in depression symptoms and in correlates of symptoms in people living with HIV.

Experimental infection of Calomys callosus with atypical strains of Toxoplasma gondii shows gender differences in severity of infection.

There is a significant genetic diversity of Toxoplasma gondii in Brazil. Two parasite isolates were recently obtained from chickens in Uberlândia, Minas Gerais state, Brazil, namely, TgChBrUD1 and TgChBrUD2. In this study, we investigated Calomys callosus susceptibility to these atypical T. gondii strains. Male and female animals were intraperitoneally infected with tachyzoites and monitored to evaluate body weight change, morbidity, and mortality. Immunohistochemical assay and qPCR were performed to determine the parasitism in liver, spleen, and brain. Our data showed that TgChBrUD2-infected males died earlier than TgChBrUD1-infected males and 100% of mortality was observed after 10 and 12 days of infection, respectively. Also, TgChBrUD1-infected females died earlier than TgChBrUD1-infected males and 100% of mortality was observed after 9 and 12 days of infection, respectively. Both strains were able to induce a decrease in body weight of males, but only the TgChBrUD1 strain induced an increase in body weight of females. TgChBrUD2-infected females had significantly higher parasite load in both liver and spleen in comparison to TgChBrUD1-infected females, but no significant difference was found between genders or strains when males were infected. There was higher parasitism in the liver than the brain from both males and females infected with either strain. In conclusion, C. callosus specimens are susceptible to both T. gondii atypical strains with differences between males and females in severity of infection. These findings open new prospects for understanding different aspects of T. gondii infection, including reinfection and vertical transmission with these atypical strains when utilizing this experimental model.

Gender differences in severity of sickle cell diseases in non-smokers.

To find out gender differences in severity of sickle cell diseases (SCDs) in non-smokers. Three groups of SCDs patients on the basis of red blood cell (RBC) transfusions were included. Less than 10 units in their lives were kept in Group-1, Ten units of higher in Group-2 and 50 units or higher as the Third Group. Patients with a history of using one pack of cigarettes -year or above were excluded. The study included 269 patients. Mean ages of the groups were similar (28.4, 28.5, and 28.9 years, respectively). Prevalences of cases without any RBC transfusion in their lives were 7.2% and 3.7% in females and males, respectively (p<0.05). Prevalences of cases without any painful crisis were 13.8% and 6.0% in females and males, respectively (p<0.001). There was progressive increase according to mean painful crises, clubbing, chronic obstructive pulmonary disease (COPD), leg ulcers, stroke, chronic renal disease (CRD), pulmonary hypertension, and male ratio from the first towards the third groups (p<0.05, nearly for all). Mean ages of mortal cases were 29.1 and 26.2 years in females and males, respectively (p>0.05). The higher painful crises per year, digital clubbing, COPD, leg ulcers, stroke, CRD, pulmonary hypertension, and male ratio of the third group, lower male ratio of patients without any RBC transfusion, lower male ratio of patients without any painful crisis, lower mean ages of male SCDs patients with mortality, and longer overall survival of females in the world could not be explained by well known strong atherosclerotic effects of smoking alone, instead it may be explained by the dominant role of male sex in life.

Sex differences in anxiety and emotional behavior

Research has elucidated causal links between stress exposure and the development of anxiety disorders, but due to the limited use of female or sex-comparative animal models, little is known about the mechanisms underlying sex differences in those disorders. This is despite an overwhelming wealth of evidence from the clinical literature that the prevalence of anxiety disorders is about twice as high in women compared to men, in addition to gender differences in severity and treatment efficacy. We here review human gender differences in generalized anxiety disorder, panic disorder, posttraumatic stress disorder and anxiety-relevant biological functions, discuss the limitations of classic conflict anxiety tests to measure naturally occurring sex differences in anxiety-like behaviors, describe sex-dependent manifestation of anxiety states after gestational, neonatal, or adolescent stressors, and present animal models of chronic anxiety states induced by acute or chronic stressors during adulthood. Potential mechanisms underlying sex differences in stress-related anxiety states include emerging evidence supporting the existence of two anatomically and functionally distinct serotonergic circuits that are related to the modulation of conflict anxiety and panic-like anxiety, respectively. We discuss how these serotonergic circuits may be controlled by reproductive steroid hormone-dependent modulation of crfr1 and crfr2 expression in the midbrain dorsal raphe nucleus and by estrous stage-dependent alterations of γ-aminobutyric acid (GABAergic) neurotransmission in the periaqueductal gray, ultimately leading to sex differences in emotional behavior.

Effects of Gender on Severity, Management and Outcome in Acute Biliary Pancreatitis

BackgroundWe conducted a population-based cross-sectional study to examine gender differences in severity, management, and outcome among patients with acute biliary pancreatitis (ABP) because available data are insufficient and conflicting.MethodsWe analyzed 13,110 patients (50.6% male) with first-attack ABP from Taiwan’s National Health Insurance Research Database between 2000 and 2009. The primary outcome was hospital mortality. Secondary outcomes included the development of severe ABP and the provision of treatment measures. Gender difference was assessed using multivariable analyses with generalized estimating equations models.ResultsThe odds of gastrointestinal bleeding (adjusted odds ratio [aOR] 1.44, 95% confidence interval [CI] 1.18–1.76) and local complication (aOR 1.38, 95% CI 1.05–1.82) were 44% and 38% higher in men than in women, respectively. Compared with women, men had 24% higher odds of receiving total parenteral nutrition (aOR 1.24, 95% CI 1.00–1.52), but had 18% and 41% lower odds of receiving cholecystectomy (aOR 0.82, 95% CI 0.72–0.93) and hemodialysis (aOR 0.59, 95% CI 0.42–0.83), respectively. Hospital mortality was higher in men than in women (1.8% vs. 1.1%, p = 0.001). After adjustment for potential confounders, men had 81% higher odds of in-hospital death than women (aOR 1.81, 95% CI 1.15–2.86). Among patients with severe ABP, hospital mortality was 11.0% and 7.5% in men and women (p<0.001), respectively. The adjusted odds of death remained higher in men than in women with severe ABP (aOR 1.72, 95% CI 1.10–2.68).ConclusionsGender is an important determinant of outcome in patients with ABP and may affect their treatment measures.

Gender Differences among Patients with a Single Depressive Episode

Background: Studies on gender differences in depression have usually included a mixture of patients with first-episode, chronic and recurrent depression. Consequently, the results might be confounded by the history of depression among participants. The present study evaluated gender differences in sociodemographic, clinical and treatment variables among patients suffering exclusively from single-episode depression. Method: Systematic recruitment of 301 participants via the Danish Psychiatric Central Research Register and assessment by means of questionnaires and interviews regarding psychiatric diagnoses, personality traits and disorders, stressful life events, family history, and treatment response. Results: Female patients showed a higher level of neuroticism and more residual anxiety symptoms after treatment of the depression. There were no gender differences in severity of depression, psychiatric co-morbidity (including personality disorders), stressful life events prior to onset, family loading of psychiatric disorders, or treatment outcome. Conclusion: The results provide evidence for a higher level of anxiety and neuroticism among females with a recent onset of depression, whereas other clinical characteristics of first-episode depression were equivalent between male and female patients. Only patients with contact to a psychiatric hospital were included; thus, the results cannot be generalized to patients in primary care.

Evolution of Asthma Severity in a Cohort of Young Adults: Is There Any Gender Difference?

IntroductionLittle is known about the distribution of asthma severity in men and women in the general population. The objective of our study was to describe asthma severity and change in severity according to gender in a cohort of adult asthmaticsMethodsSubjects with asthma were identified from random samples of the 22 to 44 year-olds from the general population, screened for asthma from 1991 to 1993 in 48 centers from 22 countries and followed-up during 1998–2002, as part of the European Community Respiratory Health Survey (ECRHS). All participants to follow-up with current asthma at baseline were eligible for the analysis. To assess change over the follow-up, asthma severity at the two surveys was defined using standardized data on respiratory symptoms, lung function and medication according to the Global Initiative for Asthma (GINA) Guidelines. Another quantitative score (Ronchetti) further considering hospitalizations was also analysed.ResultsThe study included 685 subjects with asthma followed-up over a mean period of 8.65 yr (min 4.3-max 11.7). At baseline, asthma severity according to GINA was distributed as intermittent: 40.7%, 31.7% as mild persistent, 14% as moderate persistent, and 13.5% as severe persistent. Using the Ronchetti score derived classification, the distribution of asthma severity was 58% mild, (intermittent and mild persistent), 25.8% moderate, and 15.4% severe. Whatever the classification, there was no significant difference in the severity distribution between men and women. There was also no gender difference in the severity distribution among incident cases which developed asthma between the two surveys. Men with moderate-to-severe asthma at baseline were more likely than women to have moderate-to-severe asthma at follow-up. Using GINA, 69.2% of men vs. 53.1% of women (p = 0.09) with moderate-to-severe asthma at baseline were still moderate-to-severe at follow-up. Using Ronchetti score, 53.3% of men vs. 36.2% of women (p = 0.03) with moderate-to-severe asthma at baseline were still moderate-to-severe at follow-up.ConclusionsThere was no gender difference in asthma severity at the two surveys. However, our findings suggest that asthma severity might be less stable in women than in men.

Gender differences in patients with Parkinson's disease treated with subthalamic deep brain stimulation

We investigated gender-differences in clinical phenomenology and response to deep brain stimulation (DBS) of the subthalamic nucleus (STN) in a group of patients with advanced Parkinson's disease (PD). Thirty-eight consecutive patients with PD (22 men and 16 women), bilaterally implanted for DBS of the STN, were evaluated 1 month before and 11 to 14 months after surgery. Gender differences in severity of the disease (HY and UPDRS), ability in the activities of daily living (ADL, UPDRS II), tremor and rigidity (UPDRS III), bradykinesia (UPDRS III and hand tapping test), levodopa-induced dyskinesias (LIDs, UPDRS IV), and levodopa equivalent daily dosage (LEDD) were analyzed before and after intervention. We found a predominantly male population, with no gender-related differences in age at onset, disease progression rate, or severity of disease. Nevertheless, women had more severe LIDs than men, only before the intervention. Bradykinesia was significantly less responsive to any kind of treatment (pharmacologic and neurosurgical) in women than in men. Finally, although STN-DBS induced similar total benefits in both genders, postoperative assessment suggested that the ADL improved more in women than in men. Women and men with advanced PD appear to differ in some clinical features and in response to dopaminergic and STN-DBS treatment.
