Societal Preferences for Gender of Surgeons: A Cross-Sectional Study in the General Population of Pakistan.

BACKGROUND: Sociocultural norms and gender biases may result in surgeon gender preferences among the general public. This study aimed to understand preferences and perceptions related to surgeon gender among the general population in Pakistan, a lower-middle-income country. METHODS: A cross-sectional study was conducted by the Aga Khan University, Karachi, among the adult general population in Pakistan. Sequential mixed-mode data collection was performed via online dissemination on social media platforms and in-person surveying at different geographic locations in Karachi. RESULTS: Among 1604 respondents, 50% did not report having surgeon gender preferences in general. Among respondents with gender preferences, there was a highly significant preference for gender concordance across all surgical subspecialties (p <0.001) except cardiothoracic surgery and neurosurgery. Exceptions where women preferred a male surgeon were neurosurgery (59.7% vs. 40.3%; p <0.001) and cardiothoracic surgery (53.1% vs. 46.9%; p <0.001). Moreover, respondents felt more comfortable communicating with (67.6%) and being examined by (73.3%) gender concordant surgeons. Men more commonly perceived male surgeons as more competent (26% vs. 14.5%; p <0.001) and warmer (18.3% vs. 9.8%; p <0.001) than female surgeons. Nevertheless, the most important factors influencing selection of a surgeon were the surgeon's reputation (69.6%) and experience (50.5%). Most respondents (84.5%) believed that more females should practice surgery. CONCLUSION: While around half of respondents do not have gender preferences, a significant proportion prefers a gender concordant surgeon across subspecialties. In a society where conservative sociocultural norms play a significant role when seeking health care, this makes yet another compelling argument for gender parity in surgery.

Serum proteomic analysis in esophagectomy patients with postoperative delirium: A case-control study.

BACKGROUND: Postoperative delirium occurs in up to 80% of patients undergoing esophagectomy. We performed an exploratory proteomic analysis to identify protein pathways that may be associated with delirium post-esophagectomy. OBJECTIVES: Identify proteins associated with delirium and delirium severity in a younger and higher-risk surgical population. METHODS: We performed a case-control study using blood samples collected from patients enrolled in a negative, randomized, double-blind clinical trial. English speaking adults aged 18 years or older, undergoing esophagectomy, who had blood samples obtained were included. Cases were defined by a positive delirium screen after surgery while controls were patients with negative delirium assessments. Delirium was assessed using Richmond Agitation Sedation Scale and Confusion Assessment Method for the Intensive Care Unit, and delirium severity was assessed by Delirium Rating Scale-Revised-98. Blood samples were collected pre-operatively and on post-operative day 1, and discovery proteomic analysis was performed. Between-group differences in median abundance ratios were reported using Wilcoxon-Mann-Whitney Odds (WMWodds1) test. RESULTS: 52 (26 cases, 26 controls) patients were included in the study with a mean age of 64 (SD 9.6) years, 1.9% were females and 25% were African American. The median duration of delirium was 1 day (IQR: 1-2), and the median delirium/coma duration was 2.5 days (IQR: 2-4). Two proteins with greater relative abundance ratio in patients with delirium were: Coagulation factor IX (WMWodds: 1.89 95%CI: 1.0-4.2) and mannosyl-oligosaccharide 1,2-alpha-mannosidase (WMWodds: 2.4 95%CI: 1.03-9.9). Protein abundance ratios associated with mean delirium severity at postoperative day 1 were Complement C2 (Spearman rs = -0.31, 95%CI [-0.55, -0.02]) and Mannosyl-oligosaccharide 1,2-alpha-mannosidase (rs = 0.61, 95%CI = [0.29, 0.81]). CONCLUSIONS: We identified changes in proteins associated with coagulation, inflammation, and protein handling; larger, follow-up studies are needed to confirm our hypothesis-generating findings.

Neurological Manifestations of SARS-CoV-2: A Narrative Review.

BACKGROUND: Coronavirus disease 2019 (COVID-19) pandemic started as an outbreak in China and soon crossed borders to affect the populations in all countries of the world. During the initial course of the disease, COVID-19 was perceived as a pneumonia-like illness. However, recent findings of COVID-19 patients suggest that the virus has the potential to disseminate to different tissues and organs, and cause significant complications. SUMMARY: Neurological symptoms are of great significance as these usually present in and complicate critical cases. Many case reports and case series have documented the findings of neurological complications in COVID-19 patients. From the existing data, the most frequent symptoms in these patients were broadly classified into the central nervous system (CNS), peripheral nervous system, and skeletal muscular symptoms. CNS symptoms include meningitis, encephalitis, cerebrovascular complications, peripheral nervous system symptoms include anosmia, ageusia, and skeletal muscular symptoms include myalgias. It is postulated that the cause may be direct CNS injury through blood and neuronal pathways or indirectly because of an immune-mediated response, hypoxia caused by decreased oxygen saturation, or by the binding of subacute respiratory syndrome-coronavirus-2 to the host angiotensin-converting enzyme-2 receptors. Striking radiologic findings in COVID-19 patients with neurological symptoms have also emerged. CONCLUSIONS: As subacute respiratory syndrome-coronavirus-2 may potentially have lethal implications on the nervous system, it is important that neurologists are better informed about the spectrum of clinical manifestations, radiologic findings, and likely mechanisms of injury. Understanding the symptoms and radiologic imaging allows clinicians to consider brain imaging in any patient with suspected COVID-19 and neurological symptoms.

Prevalence and Predictors of Use of Home Sphygmomanometers Among Hypertensive Patients.

OBJECTIVE: Few studies have looked at the predictors of use of home sphygmomanometers among hypertensive patients in low-income countries such as Pakistan. Considering the importance of home blood pressure monitoring (HBPM), cross-sectional study was conducted to evaluate the prevalence and predictors of the usage of all kinds of HBPM devices. METHOD: This study was conducted in Karachi during the time period of January-February 2017. Adult patients previously diagnosed with hypertension visiting tertiary care hospitals were selected for the study. Interviews from the individuals were conducted after verbal consent using a pre-coded questionnaire. The data was analyzed using Statistical Package for the Social Sciences v. 23.0 (SPSS, IBM Corporation, NY, USA). Chi-squared test was applied as the primary statistical test. RESULTS: More than half of the participants used a home sphygmomanometer (n=250, 61.7%). The age, level of education, family history of hypertension, compliance to drugs and blood pressure (BP) monitoring, few times a month at clinics were significant determinants of HBPM (P values < 0.001). It was found that more individuals owned a digital sphygmomanometer (n=128, 51.3%) as compared to a manual type (n=122, 48.8%). Moreover, avoiding BP measurement in a noisy environment was the most common precaution taken (n=117, 46.8%). CONCLUSION: The study showed that around 40% of the hypertensive individuals did not own a sphygmomanometer and less than 25% performed HBPM regularly. General awareness by healthcare professionals can be a possible factor which can increase HBPM.
