Tackling a deadly global phenomenon: sepsis induced coagulopathy: A narrative review

Sepsis is a potentially fatal illness marked by organ failure and the two main causes of which are shock and disseminated intravascular coagulation. Multi-organ dysfunction in sepsis is mediated by the inflammatory cytokine storm, while sepsis induced coagulopathy is mediated and accelerated by activation of pro-coagulative mechanisms. Regardless of the severity of sepsis, disseminated intravascular coagulation is a potent predictor of mortality in septic patients. Additionally, oxidative stress in sepsis causes renal ischaemia and eventually acute kidney injury. The first and foremost goal is to initiate resuscitation immediately, with treatment mainly focussing on maintaining a balance of coagulants and anticoagulants. A simpler and more universal diagnostic criteria is likely to improve studies on the spectrum associated with sepsis.

Reducing post-operative length of stay, is it worth the effort?

BACKGROUND

Studies show that reducing the length of hospital stay (LOS) for surgical patients leads to cost savings. We hypothesize that LOS has a nonlinear relationship to cost of care and reduction may not have a meaningful impact on it. We have attempted to define the relationship of LOS to cost of care. We utilized the itemized bill, generated in real time, for hospital services.

MATERIALS

Adult patients admitted under General, Neuro, and Orthopedic surgery over a 3-month period, with an LOS between 4 and 14 days, were the study population. Itemized bill details were analyzed. Charges in Pakistani rupees were converted to US dollar. Ethical exemption for study was obtained.

RESULTS

Of the 853 patients, 38% were admitted to General Surgery, 27% to Neurosurgery, and 35% to Orthopedics. A total of 64% of the patients had an LOS between 4 and 6 days; 36% had an LOS between 7 and 14 days. Operated and conservatively managed constituted 82% and 18%, respectively. Mean total charge for operated patients was higher $3387 versus $1347 for non-operated ones. LOS was seen to have a nonlinear relationship to in-hospital cost of care. The bulk of cost was centered on the day of surgery. This was consistent across all services. The last day of stay contributed 2.4%-3.2% of total charge.

CONCLUSIONS

For surgical patients, the cost implications rapidly taper in the postoperative period. The contribution of the last day of stay cost to total cost is small. For meaningful cost containment, focus needs to be on the immediate perioperative period.

Empathy levels among undergraduate medical students in Karachi, Pakistan: a cross-sectional study

Empathy is a concept native to the field of medicine. However, over the course of medical school, empathy levels are expected to decline. The aim of this study was to assess the empathy levels among medical students in relation to their year of study and specialties of choice in the future.

MATERIALS AND METHODS

A cross-sectional study was conducted to assess empathy levels among students from medical colleges in Karachi, Pakistan, using an online survey. The total duration of the study was 2 months. The authors analyzed the data using SPSS version 20.

RESULTS

A total of 463 undergraduate medical students participated in this survey. The overall mean empathy score was 101.9±16.3 with 104.6±14.1 for females, which was significantly higher than the male participants. The highest empathy levels were demonstrated in fourth-year medical students with a mean empathy score of 104.1±16.3, whereas, the lowest empathy levels were found in second-year medical students with a mean empathy score of 99.8±9.4. Study participants considering emergency medicine, neurology, obstetrics/gynecology, and oncology as their specialty of choice demonstrated the highest empathy levels followed by pediatrics and internal medicine.

CONCLUSION

On average, there was a female preponderance in empathy levels among undergraduate medical students. Empathy levels among fourth-year students involved in clinical practice were greater as compared to students in their initial years of study. Further investigations are required to validate the findings of this study.

Knowledge, attitude, and perceptions about cancer genetic testing in clinical practice in Karachi, Pakistan

Healthcare professionals (HCP) play an important role in the practical application of genetic screening tests but often feel inadequately prepared for cancer genetic testing (CGT) in clinical care. As the complexity of gene-related malignancies increases, it demands HCPs' preparedness to cater to patients' needs. Therefore, the aim of our study is to assess the knowledge, attitude, and practices of HCPs in Pakistan regarding the application of cancer genetics. Our cross-sectional survey was conducted from April 2022 to June 2022 amongst HCPs at a private and a governmental institution in Karachi, Pakistan. Non-probability random convenience sampling was used to select the population; however. non-clinical HCPs, as well as Interns, were excluded from our study. A total of 210 HCPs, 56.7% (119) bearing an experience of over 5 years of clinical experience, were included in this study. Most respondents from both hospitals deemed their knowledge inadequate, with only 2% (2) and 1.8% (2) being extremely knowledgeable, respectively. 68.6% (144) HCPs displayed a positive attitude towards CGT, with 55.2% (116) participants perceiving CGT in a positive light. As compared to the private sector, significantly more HCPs in the public sector dedicated ≥ 5 h/week for CME (P = 0.006), and were better prepared to counsel patients (P = 0.021) and interpret results concerning CGT (P = 0.020). Additionally, screening tests for specific cancer types were popularly considered a worthwhile avenue of investment to improve the current state of CGT in our healthcare system [47.6% (N = 100)]. Demonstrating a lack of knowledge among Pakistani doctors, our results call upon the need for additional training concerning CGT in both the public and private sectors alike. Understanding specific gaps in knowledge may further help enhance post-graduate training programs and eventually lead to effective incorporation of CGT into our healthcare setting.

Viral infections in Pakistan: prevalence, factors affecting spread, and recommendations for control

Pakistan is endemic to a number of viral infections, owing to its humid climate, topographical variation, soaring population, and lack of education and awareness. These viruses may have several different modes of transmission, including respiratory or airborne transmission, sexual transmission, blood-borne, fecal-oral transmission, vector-borne transmission, and transmission following an organ transplant. Although several different microorganisms are responsible for causing these infections, a few viruses are found more commonly in Pakistan and are primarily responsible for causing infections. In this study, we present a review of the most recent studies on different viruses, transmitted through various transmission routes, found commonly in Pakistan, along with the prevalence of each, and recommend control measures required against these viruses.

Top 100 Cited Articles on Clinical Hematopoietic Stem Cell Transplantation: A Bibliometric Analysis

We conducted a bibliometric analysis to identify scholarly impact and factors associated with the top 100 cited articles on clinical hematopoietic stem cell transplantation (HSCT). In January 2021, a title-specific search was conducted. Non-HSCT and pre-clinical (in-vitro and animal) studies were excluded. A total of 39,406 records were identified and a list of the top 100 articles was made. Articles included in our study were characterized by the citations received, publication year, topic, study design, authors, h-index, and institutions. Linear regression analyses were performed. The 100 most cited articles were published over 52 years from 1968 to 2020, with a maximum number of articles (n = 40) published in the 1990s decade. Top-100 articles were cited 62,002 times with a median citation count of 465 (range 336–2240). The top-cited articles originated from 12 countries. United States contributed 69 articles. The University of Washington Fred Hutchinson Cancer Center (n = 15) was the leading institution. Blood (n = 32) and New England Journal of Medicine (n = 31) made the greatest contribution, and 52 manuscripts were clinical trials. The first author's H-index significantly correlated with citation count while journal impact factor, years since publication, first author's gender, and the number of authors did not have a significant association with the number of citations. In a multivariate regression model, the first author's h-index (regression coefficient 5.46, 95% confidence interval 2.99 to 7.93, p < 0.001) independently correlated with the citation count. Our study highlights the most influential articles on clinical HSCT and provides valuable insight for future research needs of the specialty.

Morphological changes in the experimental model of polycystic ovary syndrome and effects of vitamin D treatment

AIM

This research was designed to develop an animal model by inducing polycystic ovary syndrome (PCOS) with dehydroepiandrosterone (DHEA) and observe reproductive and morphological changes after treatment with vitamin D.

MATERIALS AND METHODS

Thirty pre-pubertal female Sprague-Dawley (SD) dams were recruited. The animals were distributed 10 each in control, PCOS and vitamin D-treated groups. In control group 0.2 ml of sesame oil was given. PCOS group was administered DHEA by the daily dose of 6 mg/kg for 30 days. In vitamin D-treated group, animals were injected 6 mg/kg/day DHEA daily and 120 ng 1, 25(OH) 2D3/100 g subcutaneously once a week. The occurrence of reproductive phenotypic PCOS was evaluated by estrous cycle, morphology and histological changes of ovary, uterus on light microscope.

RESULTS

The results of this study showed significant weight gain, obesity, and estrous irregularity in PCOs group as compared to control and vitamin D-treated group.

CONCLUSION

Administration of vitamin D (120 ng 1, 25(OH) 2D3/100) improved the cycle characteristics, reduced body weight and morphological features in PCOS induced animals. The results support the effect of vitamin D treatment for metabolic and reproductive characteristic features in PCOS females.

Inflammatory markers as prognosticators of cardiovascular dysfunction in hypothyroid patients

Hypothyroidism is a condition characterized by reduced circulating levels of thyroid hormones, T3 (tri-iodothyronine) and T4 (tetra-iodothyronine) which are produced by the thyroid gland, and increased levels of Thyroid Stimulating Hormone (TSH) from the anterior pituitary (1). The cardiovascular system is among the main targets of thyroid hormones (2), therefore, most descriptive signs and symptoms of thyroid disorders are due to their effects on the cardiovascular system (3). Direct actions of altered thyroid hormones on heart and indirect impacts through inflammatory markers, such as C-reactive protein (CRP), Interleukin-6 (IL-6) and Homocysteine (Hcy), are of great health concern. Particularly, CRP is a renowned biomarker to measure cardiovascular risks in both healthy as well as diseased subjects (4). Moreover, IL-6 is a chief mediator of tissue injury and infection, perpetuating lymphocyte infiltration in thyroid, manifesting its inflammation (5). Additionally, Hcy, having an atherogenic nature, stimulates inflammatory chemokine production and induces oxidative stress by lowering serum anti-oxidants (6). Hence, inflammatory markers may reveal the mechanism of disease progression, and can be used as a possible tool for predicting atherosclerosis and cardiovascular events (7). The aim of the present study was to assess the risk of cardiovascular dysfunctions in hypothyroid patients through predictive inflammatory markers.
