Objective To investigate the differences in biological features between male and female patients with obstructive sleep apnea-hypopnea syndrome( OSAHS) . Methods 192 cases of patients with snoring were analyzed in the Sleep Medicine Center of West ChinaHospital fromSeptember 2004 to February 2005. The standard sleep disorder questionnaires, neck circumference, hight, weight, and all night polysomnography ( PSG) were evaluated. The clinical features of the male and female patients with OSAHS were compared. Results 170 cases of patients met the criteria of OSAHS for the apnea-hypopnea index ( AHI) more than 5 times per hour. Male gender accounted for 90% of the total patients ( male vs. female 153 vs. 17, 9∶1) . The age of male patients with OSAHS was younger than that of female ( 45. 7 ±11. 4 yearsvs. 58. 0 ±6. 1 years, P = 0. 000) . Parameters including neck circumference ( 37. 6 ±3. 2 cm vs. 35. 6 ±3. 2 cm, P =0. 000) , waist/hip rate ( 0. 94 ±0. 04 vs. 0. 9 ±0. 06, P = 0. 000) , AHI ( 36. 4 ±25. 7 vs.21. 4 ±17. 4, P =0. 004) , oxygen desaturation index ( 34. 5 ±27. 4 vs. 22. 2 ±20. 8, P =0. 035) , the number of smoking ( 52. 9% vs. 5. 9% , P = 0. 000) and drinking ( 46. 4% vs. 5. 9% , P = 0. 001) were different among the male and female patients with OSAHS. On the other hand, the morning headache ( 70. 6% vs.26. 1%, P = 0. 005) , mouth dry( 76. 5% vs. 47. 7% , P = 0. 025) , bad temper ( 52. 9% vs. 19. 0% , P =0. 004) , and hypertension ( 52. 9% vs. 20. 9% , P =0. 007) were more common in the female patients with OSAHS. Conclusion There are significant differences between male and female patients with OSAHS in prevalence, age, symptoms, and severity of the disease.

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 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.
The phenomenon of sex differences exists in patients who have abdominal aortic aneurysms (AAA). The occurrence rate of AAA is higher in male, while the rates of rupture and postoperative mortality are higher for female. This phenomenon of sex differences would affect the diagnosis, treatment and postoperative rehabilitation for AAA patients. This article reviewed the recent research status of sex differences on AAA, and explored the phenomenon of sex differences from the aspects of threshold determination, biomechanics and mechanobiology. This review points out that the sex differences on AAA could ascribe to the differences of biomechanical environment and biological properties induced by the vascular size, anatomy structure and structure components of abdominal aortic artery. The comprehensive investigations of the sex differences on AAA could help to optimize the diagnosis, treatment and device design, patient care and rehabilitation strategy of AAA based on sex differences phenomenon.
Objective To systematically review the sex differences in efficacy of immune checkpoint inhibitors (ICIs) for non-small cell lung cancer (NSCLC) patients. Methods We conducted a computer search of Medline, The Cochrane Library, and EMbase from inception to November 2022 to collect randomized controlled trials (RCTs) that assessed the efficacy of ICIs for NSCLC patients. Meta-analysis was performed using RevMan 5.4 software. Results Finally 16 RCTs with a total of 9 653 patients were included, and all were evaluated as high-quality literature using the modified Jadad scale. Meta-analysis results showed that in female NSCLC patients receiving immune therapy, the median overall survival (OS) [HR=0.72, 95%CI(0.61, 0.85), P<0.001] was longer than in males [HR=0.73, 95%CI(0.69, 0.78), P=0.401]. Males [HR=0.64, 95%CI(0.58, 0.71), P=0.171] had an advantage over females [HR=0.76, 95%CI(0.57, 1.03), P<0.001] in median progression-free survival (PFS). Conclusion Females receiving ICIs have immunotherapeutic advantages in terms of median OS compared to males, while males are more likely to benefit statistically in terms of median PFS than females.
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.
ObjectiveTo systematically evaluate the efficacy of immune checkpoint inhibitors (ICIs) in treating esophageal cancer patients of different genders. MethodsComputer searches were conducted on PubMed, The Cochrane Library, and EMbase databases to collect randomized controlled trial (RCT) on ICIs treatment for esophageal cancer patients from the establishment of the databases to January 25, 2024. Two researchers independently screened the literature and extracted data according to the inclusion and exclusion criteria. The outcome indicators were overall survival (OS) and progression-free survival (PFS), and RevMan 5.4 software was used for meta-analysis. The modified Jadad scoring scale was used to evaluate the quality of the included literature. ResultsA total of 10 RCT involving 5364 esophageal cancer patients were included in this study, with 2684 patients in the experimental group and 2680 patients in the control group. The Jadad scores of the included literature were all ≥6 points, indicating high-quality RCT. Meta-analysis results showed that female esophageal cancer patients receiving ICIs treatment [HR=0.72, 95%CI (0.59, 0.87), P<0.001] had a more significant median OS prolongation than male patients [HR=0.73, 95%CI (0.68, 0.78), P<0.001]; while male patients [HR=0.57, 95%CI (0.52, 0.64), P<0.001] had a more significant PFS prolongation than female patients [HR=0.72, 95%CI (0.55, 0.94), P=0.01]. Female patients treated with ICIs alone [HR=0.66, 95%CI (0.50, 0.87), P=0.003] had a more significant median OS prolongation than male patients [HR=0.79, 95%CI (0.72, 0.87), P<0.001]; while male patients receiving ICIs combined with chemotherapy [HR=0.67, 95%CI (0.61, 0.74), P<0.001] had a more significant median OS prolongation than female patients [HR=0.77, 95%CI (0.59, 1.01), P=0.06]. ConclusionFemale patients receiving ICIs have a slight advantage in OS compared to male patients, while male patients have an advantage in PFS. Male patients receiving ICIs combined with chemotherapy have better survival benefits than female patients, while female patients using ICIs monotherapy have better survival benefits than male patients.
