Evaluation of laboratory risk indicator for necrotizing fasciitis score as an early diagnostic tool for necrotizing fasciitis: a prospective observational study.

Introduction: From its historical identification to modern times with advancements in management modalities globally, the mortality of necrotizing fasciitis (NF) is high ranging from 19 to 30% for all affected sites. Although many diagnostic adjuncts have been developed to assist with the prompt and accurate diagnosis of NF, the primary diagnosis is still based on high clinical suspicion. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score was developed as a tool for distinguishing NF from other soft tissue infections. The main objective of this study is to evaluate LRINEC as a tool for early diagnosis of NF and differentiating it from other soft tissue infections like cellulitis. Methods: This is a single-centered, prospective observational study. Patients presenting with soft tissue infections of the limbs to the emergency department from November 2020 to October 2021 were included in this study. The clinical findings and blood parameters for the LRINEC score were collected and the score was calculated. Based on clinical suspicion of NF, patients underwent debridement and had a tissue biopsy to confirm the diagnosis. The data obtained was analyzed using SPSS version 24 and MS Excel. The AUC curve was used to calculate a cutoff, sensitivity, specificity, positive predictive value, and negative predictive values for the LRINEC score based on our study. Results: Forty-five patients with 28 males and 17 females were included. The average age was 53.667 years within a range of 19-79 years. Among them 44.4% of the patients had NF and 66.6% had other minor forms of soft tissue infections. The ROC curve obtained a cutoff value of greater than or equal to 6, with an AUC of 0.751. At this cut of value study showed a sensitivity of 85% with a specificity of 52%. Similarly, positive predictive value was found to be 58.62%, negative predictive values of 81.25%, and overall accuracy of 66.67% in early diagnosis of NF. Conclusion: In conclusion, our study showed that the LRINEC score can be a reliable tool for the early diagnosis of NF in an ED setting. This scoring system is best to be used to rule out NF.

Comparison of abdominal depth with subcutaneous fat thickness in predicting surgical site infection among patients undergoing hepatopancreatobiliary surgery: a prospective observational study.

Introduction: Surgical site infection (SSI) is a significant cause of postoperative morbidity resulting in an increased hospital stay and cost. Various measures have been used to predict SSI such as subcutaneous fat thickness (SCFT) and abdominal depth (AD) in case of abdominal surgeries. The objective of the study was to compare SCFT with AD to predict SSI in HPB surgeries. Methods: A prospective observational study was conducted from February 2020 to February 2021, which included 76 patients who underwent elective open hepatopancreatobiliary surgeries. SCFT and AD at the level of the umbilicus were measured preoperatively using the computed tomography abdomen. The occurrence of SSI was evaluated in correlation with SCFT and AD. SCFT and AD were compared using the receiver operating characteristic curve for prediction of SSI. Results: Twenty-five (32.3%) patients who underwent elective HPB surgeries developed SSI. 72% of the SSI were superficial. In multivariate analysis, only SCFT was associated with SSI, which was statistically significant. It was compared with AD using the receiver operating characteristic curve where SCFT proved to be better at predicting SSI (AUC=0.884) with cut-off =2.13 cm, sensitivity 84%, and specificity 86%), compared to AD with an AUC of 0.449. Conclusion: SSI is the common cause of increased morbidity following hepato-pancreato-biliary surgeries with risk factors including SCFT and AD. Approximately one-third of patient developed SSI, with most the common being superficial SSI. SCFT at the incision site was associated with an increased rate of SSI and the better predictor for SSI as compared with the AD.

Jejunal diverticulum and pneumatosis intestinalis presenting as pneumoperitoneum: A case report.

INTRODUCTION AND IMPORTANCE: Jejunal diverticulum is a rare condition that affects less than 0.5 % of population. Pneumatosis is also a rare disorder marked by gas in the intestinal wall's submucosa and subserosa. Both the conditions are rare cause of pneumoperitoneum. PRESENTATION OF CASE: A case of 64 years female presented with acute abdomen and upon investigation found to have pneumoperitoneum. Exploratory laparotomy was done and intraoperatively there was multiple jejunal diverticula and pneumatosis intestinalis in separate segments of bowel and closure was done without any resection of bowel segments. CLINICAL DISCUSSION: Small bowel diverticulosis was considered to be an incidental anomaly; however, it is now thought to be acquired. Pneumoperitoneum is a common complication of diverticula perforation. The occurrence of pneumatosis cystoides intestinalis or subserosal dissection of air around the colon or adjacent structures has been linked to pneumoperitoneum. Complications should be managed accordingly however, occurrence of short bowel syndrome should be considered before doing resection anastomosis of involved segment. CONCLUSION: Jejunal diverticula and pneumatosis intestinalis both are rare cause of pneumoperitoneum. Combination of both the condition giving rise to pneumoperitoneum is extremely rare. These conditions can give rise to diagnostic dilemma in clinical practice. One should always think these as differentials when patient with pneumoperitoneum are encountered.

Knowledge and attitude toward COVID-19 booster dose among health care professionals in Nepal: a cross-sectional study.

Vaccination has become the most effective way to combat the coronavirus disease 2019 (COVID-19) pandemic. As there have been reports of a gradual decline in the protection it offers, many countries have decided to administer booster doses of the COVID-19 vaccine. In Nepal, booster doses have been introduced to frontline health workers as a priority group. Therefore, this study aims to assess the knowledge and attitude of health care professionals toward booster doses of COVID-19 vaccines in Nepal. Methods: A cross-sectional study was conducted from December 2021 to January 2022 among health care professionals working at public health facilities in Nepal. Multivariable logistic regression was performed to identify predictors that correlate with knowledge and attitude toward COVID-19 booster dose. P value less than 0.05 was considered statistically significant. Results: A total of 300 participants were included in the final analysis. Among the study participants, 68.0% and 78.6% had good knowledge and favorable attitude toward COVID-19 booster dose, respectively. Female health care workers and those who had received a single dose of COVID-19 vaccine had significantly lower odds of having good knowledge of COVID-19 booster dose. Similarly, participants with lower educational levels and those who had received a single dose of COVID-19 vaccination had an unfavorable attitude toward COVID-19 booster dose. Conclusion: This study showed a satisfactory level of knowledge and attitude of health care professionals toward COVID-19 booster dose in Nepal. Health care professionals' positive attitude toward COVID-19 booster dose vaccine is key to the patient and community safety. Personalized education and risk communication can aid in improving overall awareness and attitudes toward COVID-19 booster dose in such populations.

Multi-stage transcriptome profiling of the neglected food-borne echinostome Artyfechinostomum sufrartyfex reveal potential diagnostic and drug targets.

Lack of effective surveillance and control methods for neglected helminth diseases particularly in context of rural areas in India is a serious concern in terms of public health. With regard to the emerging food-borne echinostomid Artyfechinostomum sufrartyfex infection in the country, the current study is an in silico attempt to screen for plausible diagnostic and drug targets against the trematode. Transcriptome of adult, encysted and excysted metacercaria stages of the parasite was generated using Illumina sequencing platform. A de-novo assembly strategy utilizing transcriptome data generated from the three lifecycle stages was followed to generate the representative transcripts. Longest open reading frames identified for the transcripts were further conceptually translated into their respective protein sequences. Detailed analysis of this dataset through various bioinformatics pipelines and tools eventually identified 14 credible diagnostic and 10 drug targets along with their FDA-approved and ZINC molecules. Some of the important diagnostic candidates include thioredoxin peroxidase, haemoglobinase, cathepsin L, cathepsin L-like and B-like cysteine proteases. Among the drug targets, uncharacterized sodium dependent transporter and bifunctional protein Aas were identified as top targets exhibiting significant interaction with Rifamycin and ZINC02820058 molecule, respectively. Further, B-cell epitope analysis of the diagnostic targets revealed unique epitopes for 10 of them thus indicating their potential role in specific diagnosis of the parasite. The diagnostic candidates along with a number of lesser known drug targets and their ligand molecules identified in this study provides a reasonable basis for evaluation and development of future intervention strategies against A. sufrartyfex.
