Objective To compare neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV) in age at diagnosis, gender and disease laterality. Methods One hundred fourteen nAMD patients (114 eyes) and 145 PCV patients (186 eyes) diagnosed by fundus fluorescein angiography (FFA) and indocyanine green angiography were enrolled in this retrospective study. The age at diagnosis, gender and disease laterality of all the patients were collected. Independent sample t-test, chi;2 test and Fisher's exact test were used to compare the age at diagnosis, gender and disease laterality between nAMD and PCV patients. Results The mean age at diagnosis of nAMD group and PCV group were (68.30plusmn;9.86), (65.67plusmn;9.04) years respectively, the difference was statistically significant (t=-2.168, P=0.031). The patients under 70 years old accounts for 50.88% in nAMD group, which is lower than that in PCV group (63.45%), the difference was statistically significant (chi;2 =4.138, P=0.042). The male/female ratio of nAMD group and PCV group were 3.56∶1 and 2.02∶1 respectively, the difference was statistically significant (chi;2 =3.937, P=0.047). Thirty patients (26.32%) and 41 patients (49.46%) were affected unilaterally in nAMD and PCV group, respectively. The difference of bilateral incidence between two groups was not statistically significant (chi;2 =0.123, P=0.726). There were 69 right eyes (47.92%) and 75 left eyes (52.08%) in nAMD group, 92 right eyes (49.46%) and 94 left eyes (50.54%) in PCV group. The difference of disease laterality between two groups was not statistically significant (chi;2 =0.078，P=0.637). Conclusions PCV patients present at younger age than nAMD. nAMD is more prone to affected males than PCV. Nearly a quarter patients are bilateral in nAMD or PCV, there is no difference in bilateral incidence between these two diseases.
ObjectiveTo explore the influence factors of gallstone. MethodsClinical data of 511 patients who were admitted to our hospital from Apr. 2015 to Apr. 2016 were retrospectively analyzed. ResultsOf 511 patients, there were 274 patients with gallstone (gallstone group) and 237 patients without gallstone (control group). Univariate analysis results showed that, no significant difference of age, gender, and diabetes was found between gallstone group and control group (P > 0.050), but the levels of serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL-C), and fasting blood glucose (FBG) were significantly higher in patients of gallstone group (P < 0.050), but the level of serum high density lipoprotein (HDL-C) was significantly lower in patients of gallstone group (P=0.001). Logistic regression results showed that four factors including diabetes〔OR=4.491; 95% CI is (2.021, 9.976); P < 0.001〕, the serum TC〔OR=2.548; 95% CI is (1.944, 3.338); P < 0.001〕, HDL-C〔OR=0.115; 95% CI is (0.056, 0.237); P < 0.001〕, and FBG〔OR=1.277; 95% CI is (1.086, 1.502); P=0.003〕 entered the final regression model after controlling confounding factors. The results showed that patients who combined with diabetes, high levels of serum TC and FBG, and low level of serum HDL-C, had higher ratio of galls-tone. ConclusionDiabetes, high-level of serum TC and FBG, low-level of serum HDL-C were risk factors of gallstone.
Objective To explore the impact of gender difference in 90-day outcomes after mechanical thrombectomy for acute cerebral infarction. Methods A prospective registration, observational, and retrospective analysis study was carried out. Patients with acute cerebral infarction who were admitted to the Department of Neurology of the First Affiliated Hospital of Chengdu Medical College and the Department of Neurology of Nanjing First Hospital between June 2015 and June 2019 were collected. Patients were divided into two groups based on gender. The detailed demographic, laboratory examination, imaging examination and clinical data were collected. Then, the data were analyzed using univariate and multivariate logistic regression analyses. Results A total of 298 patients were included. Among them, there were 185 males and 113 females. The differences in age, smoking, atrial fibrillation, using antiplatelet drugs before stroke, TOAST classification, and involved cerebrovascular sites between the two groups were statistically significant (P<0.05), and there was no statistically significant difference in other baseline data between the two groups (P>0.05). The results of univariate logistic regression analysis showed that the rate of 90-day favourable outcome of female patients was lower than that of male patients [odds ratio (OR)=0.462, 95% confidence interval (CI) (0.275, 0.775), P=0.030]. The results of multivariate logistic regression analysis showed that, after adjusting for confounding factors, there was no independent correlation between gender and the 90-day favourable outcome of patients with acute cerebral infarction who underwent mechanical thrombectomy [OR=1.511, 95% CI (0.745, 3.066), P=0.253]. Conclusion The gender has no significant effect on the 90-day favourable outcome of acute cerebral infarction patients treated with mechanical thrombectomy.

Objective To explore the correlation between gender and long-term prognosis of patients with type-B acute aortic dissection (AAD) after endovascular therapy (EVT). Methods From January to December 2012, all patients with type-B AAD undergoing EVT were enrolled by retrospective and observational study. They were divided into male and female groups. Kaplan-Meier analysis was used to analyze the correlation between gender and the cumulative survival rate. Results A total of 131 tyep-B AAD patients who had undergone EVT were selected, including 97 males (74.0%), and 34 females (26.0%). The medium follow-up duration was 2.1 years. Smoking history, cholesterol, white blood cell count, hemoglobin, creatinine and uric acid of the patients in males were higher than those in females (P<0.05); while the difference in other indexes were not significant (P>0.05). The inhospital mortality of male patients was 10 (10.3%), and was 3 (8.8%) in female patients; there was no significant difference between the two groups (P=0.803). Kaplan-Meier analysis showed that there was no significant difference in cumulative survival rate between the two groups (84.5% vs. 82.4%; Logrank test χ2=0.023, P=0.880). Conclusion No correlation between gender and long-term prognosis in patients with type-B AAD after EVT is found.
ObjectiveTo explore the spectrum and frequency of respiratory symptoms in outpatients clinics.MethodsPatients were enrolled from outpatient clinic of Guangzhou Institute of Respiratory Disease. Information about respiratory symptoms especially cough was obtained from the survey questionnaire from July 2013 to August 2013 .ResultsA total of 900 were eligible out of 939 questionnaires. The mean age of the patients was (48.9±18.3) years, 453 (50.3%) were males, 447 (49.7%) were females. The cases of cough, wheeze, polypnea, chest distress, pharyngalgia, catarrh, chest pain, throat itching, fever, hemoptysis and other symptom was 687 (76.3%), 310 (34.4%), 307 (34.1%), 173 (19.2%), 107 (11.9%), 101 (11.2%), 82 (9.1%), 59 (6.6%), 36 (4.0%), 10 (1.1%) and 129 (14.3%) out of the patients, respectively. In patients with cough, 69.5% of them considered cough as their predominant symptom, and 22.1% of them reported that cough was the only symptom. 56.3% of cases were chronic cough, while acute and subacute cough accounted for 29.7% and 14.0%, separately. The proportion of female in acute cough was significantly higher than that of males (60.3%vs. 39.7%, P<0.01).ConclusionsCough, especially the chronic cough is the most common reason for patients who seeking health care in outpatient clinic of respirologist. There are more females suffered from acute cough than males.
Knee osteoarthritis (KOA) is one of the common degenerative joint diseases, which is more common in the middle-aged and elderly population. It shows significant gender differences, with a significantly higher incidence rate in women than in men, seriously affecting the quality of life of patients. However, there are few research reports on the correlation between gender differences and the incidence of KOA both domestically and internationally. Therefore, this article will summarize and analyze the potential causes of gender differences related to the incidence of KOA from five aspects: hormone levels, anatomical biomechanical characteristics, genes, obesity, and exercise-muscle factors. Through a comprehensive review of research progress, the aim is to provide a theoretical basis for gender based personalized treatment of KOA in clinical practice.
Objective To investigate the difference in first onset age, family history and medication compliance between male and female patients with schizophrenia in communities. Methods We used self-designed questionnaire to survey and analyze 372 cases of schizophrenia between June to August 2014. Results There were no significant differences between male and female schizophrenic patients in the family history, personality before the disease, education level, age, and the onset type and disease course (P > 0.05). The first onset age of male patients [(24.92±8.22) years] was significantly earlier than female patients [(27.02±11.28) years] and the difference was statistically significant (P < 0.05). The number of unmarried male patients (115, 58.97%) was significantly more than unmarried females (81, 45.76%) and the difference was statistically significant (P < 0.05). The full medication compliance rate of female patients (127, 71.75%) was significantly better than that of male patients (115, 58.97%) (P < 0.05). Conclusion The first onset age, marital status and medication compliance are significantly different between the two genders of patients with schizophrenia, which indicates that prevention, treatment and recovery measures for male and female patients should be differentiated.
ObjectiveTo analyze the trends and major risk factors of intracerebral hemorrhage (ICH) disease burden by gender in China and globally from 1990 to 2021, and to predict ICH incidence and mortality in China and globally by gender from 2022 to 2046. MethodsBased on the Global Burden of Disease Study 2021 (GBD 2021), data on ICH in China and globally from 1990 to 2021 were collected. Age-standardized incidence rate (ASIR), age-standardized mortality rate (ASMR), and age-standardized disability-adjusted life years (ASDR) were used to assess ICH disease burden and risk factors by gender. Joinpoint regression models were employed to calculate annual percentage change (APC) and average annual percentage change (AAPC) for trend analysis. The Bayesian age-period-cohort (BAPC) model was applied to predict ICH incidence and mortality from 2022 to 2046. ResultsFrom 1990 to 2021, ASIR, ASMR, and ASDR for ICH in China and globally showed declining trends across genders (P<0.05). For males in China and globally, the AAPC for ASIR was −1.63% (95%CI −1.69% to −1.57%) and −1.14% (95%CI −1.20% to −1.07%), respectively. For females in China and globally, the AAPC for ASIR was −2.27% (95%CI −2.35% to −2.18%) and −1.40% (95%CI −1.40% to −1.33%), respectively. The AAPC for ASMR in Chinese and global males was −1.81% (95%CI −2.07% to −1.55%) and −1.29% (95%CI −1.43% to −1.15%), respectively, while for females in China and globally, it was −2.74% (95%CI −2.94% to −2.54%) and −1.69% (95%CI −1.82% to −1.55%), respectively. The AAPC for ASDR in Chinese and global males was −1.91% (95%CI −2.11% to −1.72%) and −1.39% (95%CI −1.52% to −1.26%), respectively, and for females in China and globally, it was −2.93% (95%CI −3.07% to −2.79%) and −1.85% (95%CI −1.96% to −1.74%), respectively. By 2046, the predicted ASIR for ICH in Chinese and global males is projected to be 38.08/100 000 and 44.23/100 000, respectively, and 28.27/100 000 and 29.15/100 000 for Chinese and global females. The ASMR is predicted to reach 37.01/100 000 and 68.57/100 000 for Chinese and global males, and 22.39/100 000 and 29.45/100 000 for Chinese and global females, respectively. ConclusionThe disease burden of ICH in China has demonstrated a declining trend, yet it persistently exceeds global averages and exhibits pronounced gender disparities. There is an urgent need to enhance focus on these gender−specific variations and implement precisely targeted interventions tailored to the distinct risk factor profiles of each gender, in order to achieve further reductions in ICH−related disease burden.
ObjectiveTo explore the correlation between coronary artery plaque composition and the gender via 128-slice spiral CT coronary angiography (128-SCTCA). MethodsBetween January and December 2012, 143 patients with coronary artery plaque diagnosed by 128-SCTCA were selected. The patients were divided into group A (no more than 50 years old, n=37) and group B (over 50 years old, n=106). ResultsThere were 29 male patients in group A, with 70 plaques including 30 fibrous plaques, 17 mixed plaques, 11 soft plaques, 12 calcified plaques; and the other 8 female patients had 13 plaques including 7 fibrous plaques, 2 mixed plaques, 2 soft plaques, and 2 calcified plaques. In group B, 56 male patients had 116 plaques, including 48 mixed plaques, 40 fibrous plaques, 14 soft plaques and 14 calcified plaques; the other 50 female patients had 90 plaques, including 36 mixed plaques, 22 fibrous plaques, and 16 soft plaques and calcified plaques. The differences of the plaque composition between males and females were not significant both in group A (χ2=0.664, P>0.05) and group B (χ2=3.708, P>0.05). ConclusionThere is no obvious correlation between gender and coronary plaque composition.
