BACKGROUND
There is growing interest in gender differences in acute stroke worldwide. However, no known studies have been published on the differences in prognosis of hyperacute intracerebral hemorrhage between genders among Asians, particularly Filipinos.
OBJECTIVESCompare gender differences in the prognosis of hyperacute intracerebral hemorrhage in terms of baseline demographic and radiologic profile, as well as, clinical outcomes.
METHODSThis is a retrospective cohort study involving a chart review of all patients diagnosed with hyperacute Intracerebral Hemorrhage admitted at a tertiary hospital from January 2021 to May 2023. Patients were grouped according to their gender and baseline demographic, radiologic and clinical outcomes were assessed and compared between two groups.
RESULTSNo statistical difference was found between stroke risk factors between the two groups. However, males tend to have higher percentages of intraventricular extension (29.2 %. (n=28) vs 30.6% (n=11) and increased hematoma volume compared to their female counterparts (n=39, 83% vs n=11, 68%). In addition, males had a higher number of ICU admissions (42.7% (n= 41) vs. 33.3% (n= 12) and mortality (46.9%( n=45) vs. 30.6% (n=11), though the results were not statistically significant.
CONCLUSIONIn patients with hyperacute intracerebral hemorrhage, gender does not influence on its radiologic and clinical outcome.

A growing number of studies have identified sex differences in response to general anesthesia; however, the underlying neural mechanisms are unclear. The medial preoptic area (MPA), an important sexually dimorphic structure and a critical hub for regulating consciousness transition, is enriched with estrogen receptor alpha (ERα), particularly in neuronal clusters that participate in regulating sleep. We found that male mice were more sensitive to sevoflurane. Pharmacological inhibition of ERα in the MPA abolished the sex differences in sevoflurane anesthesia, in particular by extending the induction time and facilitating emergence in males but not in females. Suppression of ERα in vitro inhibited GABAergic and glutamatergic neurons of the MPA in males but not in females. Furthermore, ERα knockdown in GABAergic neurons of the male MPA was sufficient to eliminate sex differences during sevoflurane anesthesia. Collectively, MPA ERα positively regulates the activity of MPA GABAergic neurons in males but not in females, which contributes to the sex difference of mice in sevoflurane anesthesia.

OBJECTIVES:
To study the effect of sex on the clinical outcome of extremely preterm infants (EPIs)/extremely low birth weight infants (ELBWIs) by propensity score matching.
METHODS:
A retrospective analysis was performed for the medical data of 731 EPIs or ELBWIs who were admitted from January 1, 2011 to December 31, 2020. These infants were divided into two groups: male and female. A propensity score matching analysis was performed at a ratio of 1:1. The matching variables included gestational age, birth weight, percentage of withdrawal from active treatment, percentage of small-for-gestational-age infant, percentage of use of pulmonary surfactant, percentage of 1-minute Apgar score ≤3, percentage of mechanical ventilation, duration of mechanical ventilation, percentage of antenatal use of inadequate glucocorticoids, and percentage of hypertensive disorders in pregnancy. The two groups were compared in the incidence rate of main complications during hospitalization and the rate of survival at discharge.
RESULTS:
Before matching, compared with the female group, the male group had significantly higher incidence rates of neonatal respiratory distress syndrome, bronchopulmonary dysplasia (BPD), severe intraventricular hemorrhage, periventricular leukomalacia, necrotizing enterocolitis, and patent ductus arteriosus (P<0.05), while after matching, the male group only had a significantly higher incidence rate of BPD than the female group (P<0.05). There was no significant difference in the rate of survival at discharge between the two groups before and after matching (P>0.05).
CONCLUSIONS
Male EPIs/ELBWIs have a higher risk of BPD than female EPIs/ELBWIs, but male and female EPIs/ELBWIs tend to have similar outcomes.

Background:
Cardiovascular disease is the leading cause of death in both genders worldwide. Gender differences in clinical presentation and treatment have been reported.
Objective:
This study aims to describe and compare the cardiovascular risk factors and management strategies for primary prevention among Filipinos.
Methods:
An analytical cross-sectional study was done on 2,082 patients at the Preventive Cardiology Clinic of a tertiary referral center in Quezon City, Philippines from January 1, 2002 to December 31, 2017.
Results:
Seventy-two percent of the patients were females with a higher mean age compared to males (57.67 + 10.50 vs 55.66 + 11.82, p 0.002). There were more women who were unemployed (75.2 vs 45.9, p<0.001). There was no significant difference in the prevalence of hypertension (68.6% vs 67.9%, p=0.542) and type 2 diabetes mellitus (19.8% vs 21.5%, p=0.437) in both genders. Beta blockers (24.1%), calcium channel blockers (22.9%) and angiotensin receptor blockers (22.1%) were the most commonly prescribed anti-hypertensive drugs. Biguanides were the most commonly prescribed glucose-lowering drug (11.3%). Compared to men, more women had dyslipidemia (51.8% vs 38.6%, p<0.001). Statins were more commonly prescribed in women (22.4 vs 18.1%, p=0.033).
Conclusion
There were significantly more women seen in our Preventive Cardiology clinic. Smoking and alcoholic drinking were higher in males. BMI, total cholesterol and HDL were significantly higher in females than in males.

BACKGROUND:
The onset and clinical presentation of systemic lupus erythematosus (SLE) are sex-related. Few studies have investigated the distinctions in clinical characteristics and treatment preferences in male and female SLE patients in the initial cohort. This study aimed to improve the understanding of Chinese SLE patients by characterizing the different sexes of SLE patients in the inception cohort.
METHODS:
Based on the initial patient cohort established by the Chinese SLE Treatment and Research Group, a total of 8713 patients (795 men and 7918 women) with newly diagnosed SLE were enrolled between April 2009 and March 2021. Of these, 2900 patients (347 men and 2553 women) were eligible for lupus nephritis (LN). A cross-sectional analysis of the baseline demographic characteristics, clinical manifestations, laboratory parameters, organ damage, initial treatment regimens, and renal pathology classification was performed according to sex.
RESULTS:
In the SLE group, as compared to female patients, male patients had a later age of onset (male vs. female: 37.0 ± 15.8 years vs. 35.1 ± 13.7 years, P = 0.006) and a higher SLE International Collaborative Clinic/American College of Rheumatology damage index score (male vs. female: 0.47 ± 1.13 vs. 0.34 ± 0.81, P = 0.015), LN (male vs. female: 43.6% vs. 32.2%, P < 0.001), fever (male vs. female: 18.0% vs. 14.6%, P = 0.010), thrombocytopenia (male vs. female: 21.4% vs. 18.5%, P = 0.050), serositis (male vs. female: 14.7% vs. 11.7%, P = 0.013), renal damage (male vs. female: 11.1% vs. 7.4%, P < 0.001), and treatment with cyclophosphamide (CYC) (P < 0.001). The frequency of leukopenia (male vs. female: 20.5% vs. 25.4%, P = 0.002) and arthritis (male vs. female: 22.0% vs. 29.9%, P < 0.001) was less in male patients with SLE. In LN, no differences were observed in disease duration, SLE Disease Activity Index score, renal biopsy pathological typing, or 24-h urine protein quantification among the sexes. In comparisons with female patients with LN, male patients had later onset ages (P = 0.026), high serum creatinine (P < 0.001), higher end-stage renal failure rates (P = 0.002), musculoskeletal damage (P = 0.023), cardiovascular impairment (P = 0.009), and CYC use (P = 0.001); while leukopenia (P = 0.017), arthritis (P = 0.014), and mycophenolate usage (P = 0.013) rates were lower.
CONCLUSIONS
Male SLE patients had more severe organ damage and a higher LN incidence compared with female SLE patients; therefore, they may require more aggressive initial treatment compared to female patients.

Neuroscience Bulletin 2022;38(12):1439-1456
The lateral habenula (LHb), which is a critical neuroanatomical hub and a regulator of midbrain monoaminergic centers, is activated by events resulting in negative valence and contributes to the expression of both appetitive and aversive behaviors. However, whole-brain cell-type-specific monosynaptic inputs to the LHb in both sexes remain incompletely elucidated. In this study, we used viral tracing combined with in situ hybridization targeting vesicular glutamate transporter 2 (vGlut2) and glutamic acid decarboxylase 2 (Gad2) to generate a comprehensive whole-brain atlas of inputs to glutamatergic and γ-aminobutyric acid (GABA)ergic neurons in the LHb. We found >30 ipsilateral and contralateral brain regions that projected to the LHb. Of these, there were significantly more monosynaptic LHb-projecting neurons from the lateral septum, anterior hypothalamus, dorsomedial hypothalamus, and ventromedial hypothalamus in females than in males. More interestingly, we found a stronger GABAergic projection from the medial septum to the LHb in males than in females. Our results reveal a comprehensive connectivity atlas of glutamatergic and GABAergic inputs to the LHb in both sexes, which may facilitate a better understanding of sexual dimorphism in physiological and pathological brain functions.

Biomedical and Environmental Sciences 2021;34(8):623-631
Objective:
This study aims to assess the dose-response relationship between serum ferritin (SF) and metabolic syndrome (MetS) in the two sexes.
Methods:
We searched for articles on PubMed, the Cochrane Library, EMBASE, and the Web of Science databases that were published from 1950 to 2020. The summary odds ratio (
Results:
This study included 14 studies and 74,710 samples. The results of the classical meta-analysis showed that SF was positively associated with MetS (
Conclusions
Our study shows that SF is significantly and positively associated with MetS, and the risk in the male population is higher than that in the female population. This finding also supports the recommendation of using SF as an early warning marker of MetS.

Chinese Journal of Medical Genetics 2021;38(7):663-666
OBJECTIVE:
To explore gender difference in the clinical manifestations of two children with Keishi-Bukuryo-Gan syndrome (KBGS).
METHODS:
Clinical manifestations of the two children were reviewed. Genetic testing was carried out through next generation sequencing (NGS). Treatment was summarized, and the prognosis was followed up.
RESULTS:
Both children showed particular appearance including megatooth, abnormal hair distribution, hands' abnormality and language development delay. NGS revealed that both children have carried pathogenic variants of the ANKRD11 gene (c.1903_1907del and c.4911delT), which resulted in shifting of amino acid sequences starting from the Lysine and Proline at positions 635 and 1638, respectively. The female patient exhibited central precocious puberty. Her height has increased by 13 cm, and sex characteristics has retracted after treatment with leuprorelin for 23 months and recombinant human growth hormone for 1 month.
CONCLUSION
Comparison of the two cases with different genders and summary of previously reported cases found that male KBGS patients have more obvious dysmorphisms such as triangular face, synophrys, ocular hypertelorism and vertebral body abnormality, with higher morbidity of epilepsy, mental retardation, autism, congenital heart disease, immune thrombocytopenia and other complications. KBGS is an autosomal dominant disease featuring more evident peculiar appearance and global development delay. Male patients often have multi-system involvement, and multidisciplinary cooperation is required for early recognition of particular features in order to improve the prognosis.
