Background: The study is aimed to investigate the metabolic alterations and changes in biochemical parameters associated with extended mask., Methods: It was a prospective comparative study conducted on 129 participants comprised of 37 healthy controls and 92 health care workers using different kind of masks like, cloth mask, surgical masks and N95-FFR/PPE. Two samples on day-1 and day-10 were collected for analysis of blood gas parameters, serum hypoxia-inducible factor-α (HIF-α), and erythropoietin (EPO)., Results: Oxygen saturation percentage (sO 2 ) of 72.68 (P = 0.033) was significantly low, whereas, Na + (P = 0.05) and Ca 2+ (P < 0.001) were raised in exposed individuals than the healthy controls. The serum HIF-α level of 3.26 ng/mL, was considerable higher in the exposed individuals than controls (P = 0.001). pO 2 and sO 2 were the lowest and HIF-α and EPO were raised in N95-FFR/PPE of all mask users (P < 0.01). A significant difference was evidenced for pCO 2 , pH, Na + , Ca 2+ , and EPO in the exposed group. A positive correlation between the duration of mask use (in hours) with HIF-α (r = 0.247, P = 0.005) and Ca 2+ (r = 0.306, P < 0.001) was observed. The major complaints in N95-FFR/PPE users were headache (15.2%) and polydipsia (33.3%)., Conclusion: The study findings depicted a significant metabolic alterations in PPE/N95 users which could be due to chronic hypoxic exposure of the tissues.

Background and Objective: This study explored the role of various laboratory biomarkers on inflammatory indices for predicting disease progression toward severity in COVID-19 patients., Methods: This retrospective study was conducted on 1233 adults confirmed for COVID-19. The participants were grouped undermild, moderate, and severe grade disease. Serum bio-inflammatory index (SBII) and systemic inflammatory index (SII) were calculated and correlated with disease severity. The study variables, including clinical details and laboratory variables, were analyzed for impact on the inflammatory indices and severity status using a sequential multiple regression model to determine the predictors for mortality. Receiver operating characteristics defined the cut-off values for severity., Results: Among the study population, 56.2%, 20.7%, and 23.1% were categorized as mild, moderate, and severe COVID-19 cases. Diabetes with hypertension was the most prevalent comorbid condition. The odds for males to have the severe form of the disease was 1.6 times (95% CI = 1.18-2.18, P = 0.002). The median (inter-quartile-range) of SBII was 549 (387.84-741.34) and SII was 2097.6 (1113.9-4153.73) in severe cases. Serum urea, electrolytes, gamma-glutamyl transferase, red-cell distribution width-to-hematocrit ratio, monocytopenia, and eosinopenia exhibited a significant influence on the SpO 2 , SBII, and SII. Both SBII (r = -0.582, P < 0.001) and SII (r = -0.52, P < 0.001) strongly correlated inversely with SpO 2 values [Figures 3a and 3b]. More than 80% of individuals admitted with severe grade COVID-19 had values of more than 50 th percentile of SBII and SII. The sensitivity and specificity of SBII at 343.67 for severity were 81.4% and 70.1%, respectively. SII exhibited 77.2% sensitivity and 70.8% specificity at 998.72., Conclusion: Serial monitoring of the routinely available biomarkers would provide considerable input regarding inflammatory status and severity progression in COVID-19., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Journal of Family Medicine and Primary Care.)

Deregulated immune response and raised inflammation are the cardinal laboratory features in COVID-19 infection reflecting severity of condition. Detection of the markers will help in early diagnosis with timely therapeutic implementation and effective outcome. Observational studies have suggested alteration in these parameters with severity of the condition. This systematic review and meta-analysis was conducted to assess the relevance of the fact. Observational studies from databases were scrutinised and 3669 articles were identified. Further screening, based on the inclusion criteria a total of 19 articles with 3115 participants, were reviewed for meta-analysis using random effects model. Any data in median and interquartile range were converted to mean ± SD. There was a significant rise in total leukocyte count, C-reactive protein, ferritin, IL-6, IL-10, procalcitonin in severe cases but absolute lymphocyte count, CD4+ and CD8+ registered a fall in severe cases in comparison to non-severe group. Immune and inflammatory markers are significantly altered and related to severity of manifestation in COVID-19 infection., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Journal of Family Medicine and Primary Care.)

Cutaneous manifestation of COVID 19 in children has not yet been reviewed systematically. Hence, this review gives the clinicians a future direction to be vigilant for skin presentations during pandemics. The Pubmed database used for literature search with keywords COVID 19, children, and skin in different combinations. Articles published in English with cases of age one month to 18 years were eligible. The outcome included varied aspects of cutaneous and COVID 19 infection. The authors did not register review protocol. Of 51 publications identified, 13 studies containing 149 children met the eligibility criteria. Acrally located erythematous maculopapular lesion was the most common finding in 138 children. The researcher reported Erythema multiforme, varicella like exanthem, and Kawasaki disease like presentations in the rest of the cases. The duration of the skin lesion was 1 2 weeks in 43%. Skin biopsy done in 18 patients revealed superficial and deep perivascular and peri eccrine lymphocytic infiltrate and lymphocytic vasculitis. RT PCR was positive13.8% cases. Serological markers for HSV, parvovirus B19 analyzed across various studies, were negative, except positive mycoplasma pneumonia in 2 of 20 cases tested. Clinicopathologic analysis established chilblains like lesion in 43% cases with no confirmed etiology like cold exposure, autoimmune dysfunction, drug reaction, or viral infection. The usual cephalo caudal spread of a viral exanthem was also missing. However, a low number of discussed cases was a limitation of the study. The absence of any confirmed etiology for such cutaneous manifestations, the possibility of COVID 19, should be explored and thoroughly evaluated and isolated during such a pandemic., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Journal of Family Medicine and Primary Care.)

Objectives: LBW is the strong determinant of neonatal morbidity and mortality with a global prevalence of nearly 15%. India's prevalence, though not yet established, ranges from 16-30% and influenced by maternal nutritional status, antenatal care and associated maternal morbidity. Hence, the study was aimed to determine the influencing parameters for occurrence of LBW., Study Design: A retrospective observational study conducted for all live newborns delivered in a tertiary care centre during the study period of twenty four months., Methods: Data from institutional medical record section was recorded on predesigned questionnaire from a total of 1216 newborns., Results: The percentage of LBW was found to be 27.55% (335/1216) with a proportion of LBW to NBW babies was approximately 1:3. The occurrence of LBW was significantly higher in babies of anemic mothers (59.39%, P < 0.0001), young mothers (30.39%, P < 0.01), mothers with parity ≥ 3 (35.71%, P < 0.05), those with <3 ANC check-up (56.88%, P < 0.0001) and those with premature delivery (71.57%, P < 0.0001). Maternal anemia (OR 4.7, 95%CI 3.4-6.7, P < 0.001); ANC with <3 visits (OR 2.2, 95%CI 1.4-3.4, P < 0.01) and prematurity (OR 7.6, 95%CI 5.1-11.2, P < 0.0001) were considered as independent risk factor for LBW. Significant association of neonatal complications was found with LBW babies (OR 1.6, 95%CI 1.1-2.5, P < 0.05)., Conclusions: Inadequate antenatal care, maternal anemia and other maternal illness causing premature delivery are considered critical determinants for LBW and thus associated with high neonatal mortality and morbidity. Continued focus for improving the overall maternal health status would lead to lowering burden of LBW., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Journal of Family Medicine and Primary Care.)
