Published: July 2023

Surgical site infections (SSIs) are a major health care associated infections and possess a great challenge to clinicians. It increases duration of hospital stay, associated morbidity and mortality and treatment cost. For prompt and appropriate management, it is necessary to understand the appropriate microbial etiology and its antimicrobial susceptibility pattern. To determine the prevalence of SSI along with its clinico-bacteriological profile and antibiogram and to correlate with the risk factors.A cross-sectional study was conducted in the Department of Microbiology of Nil Ratan Sircar Medical College & Hospital, Kolkata for a period of one year (2020-2021). Post-operative surgical site infections within 30 days after surgery were included in the study. All samples were collected from clinically suspected SSI cases and processed in the lab as per standard laboratory protocol. Vitek®2 compact system (BIOMERIEUX) was used for further identification and antimicrobial susceptibility testing. All Gram negative pathogens resistant to 3rd generation cephalosporins were screened for ESBL and AmpC. Carbapenem resistant isolates were subjected to Carba NP test for carbapenemase production. Out of 6582 surgeries, clinically suspected SSIs were detected in 220 cases. Among these 220 patients, 186 patients were confirmed as SSI in the laboratory, SSI rate being 2.83%. In 62.27% cases, growth was mono-microbial. Growth of gram negative organisms were noted in 58.72% cases and gram positive growth was 38.53%. (57.14%) was the predominant isolates followed by (35.94%). Diabetes mellitus, obesity and using prophylactic antibiotic &#62;2 hours prior to surgery were found to be significantly associated. For gram positive organism, Vancomycin and Linezolid were found to be most susceptible antimicrobials and for gram negative organisms, it was Polymyxin B and Meropenem. Most of the gram negative organisms were ESBL producer (67.97%). Rapidly emerging multi drug resistant organisms are complicating the management of surgical site infection day by day and possessing significant burden to health care system. For implementation of appropriate antimicrobial policy, it is important to identify bacteriological profile and antibiogram in every hospital.
Dehydration among the Elderly: A Comparison between Nine Different Clinical and Metabolic Criteria
Authors: Raeisi-Dehkordi Hamidreza , Shekarkhand Samira , Faghih Shiva 
Published: July 2023

Background: Dehydration, as a common problem in older adults, plays a significant role in morbidity and mortality. The elderly are more susceptible to dehydration and fluid deficiency due to age-related factors. There is not much literature concerning fluid intake in older adults. This study aims to investigate fluid intake and dehydration prevalence in older people and compare the accuracy of potential markers in the detection of dehydration.
Methods: This cross-sectional study was done on 127 old people (48 males and 79 females) selected from a nursing home in Shiraz, Iran. Socioeconomic status was assessed via interview. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), urine specific gravity (USG), urine color (UC) and bioelectrical impedance analysis (BIA), extracellular water (ECW), intracellular water (ICW), and total body water (TBW) were measured. The fluid intakes were recorded using a beverage and fluid intake questionnaire. Total fluid intakes were compared using two fluid intake guidelines (European guidelines and US guidelines) as well. Furthermore, anthropometric indices were measured.
Results: The mean age of participants was 73.01± 5.70 year. Fluid intake was 2.32 ± 0.48 liter/day. Based on urine specific gravity (USG) (˃1.020) and SBP (SBP ˂ 100 mmHg), 9.4% and 14.2% of the participants were dehydrated respectively. Among all hydration criteria, ECW had the highest potential for detection which identified 72.4% of participants as dehydrated. Among fluid intake guidelines, US guidelines were the best in dehydration diagnosis (112 individuals out of 127).
Conclusions: Although urinary markers and physical indexes (SBP and HR) could not be used to determine hydration status, BIA measurements, especially ECW, have the potential to detect dehydration. In addition, daily fluid intakes are still practical for assessment of hydration status.
Anemia and Underweight among Married Women in Yemen; Evidence from Yemen Demographic Health Survey (YDHS-2013)
Authors: Ahmad Malik Manzoor , Dahiru Tukur 
Published: July 2023

Background: Women in conflict are vulnerable to health and nutrition risks. Anemia and underweight are the common risks faced by women particularly in war torn countries. Yemen is one of the most affected places that has a fragile public health system due to the conflict. Increasing conflict has put women’s health and wellbeing at risk and has severely affected their nutritional development. Therefore, this study aims to examine the association between underweight and anemia with different risk factors among married women in Yemen.
Methods: This study used the data from Yemen demographic health survey-2013 (YDHS-2013) of married women aged 15-59 year. Bivariate and multivariate logistic models were used to study the association between anemia and underweight with various socio-economic and maternal health risk factors.
Results: A positive and significant association of socio-economic and maternal health risk factors was found with anemia and underweight. Women belonging to more prosperous groups had the lowest odds of underweight [OR=0.30, P<0.001)] and anemia [OR=0.61, P<0.001). The study also examined some key risk factors like breast feeding, iron supplements and contraceptive use among women and found a positive and significant association of these risk factors with underweight and anemia.
Conclusions: Nutritional challenges have to be addressed especially in the country like Yemen. The results clearly indicate that women in Yemen are facing acute nutritional risks of underweight and anemia. Therefore, policy interventions are required to address their nutritional needs and also empower them economically to minimize these nutritional risks. Moreover, nutrition related interventions are required to attain the targets for sustainable development goals in Yemen.
