Clinical Assessment of the Ambu® Aura-i™ as an Independent Ventilatory Device and Conduit for Fiberoptic-Guided Endotracheal Intubation in Adults.

Background and aim A novel supraglottic airway device of the second generation is the Ambu® Aura-i™. It is designed to accommodate standard cuffed tracheal tubes and is phthalate-free and compatible with MRI. The primary objectives of the research were to examine the properties and efficiency of Ambu® Aura-i™ as a means of enabling fiberoptic-guided intubation, the view of the glottis during fiber optic examination, the duration of intubation in fiber optic bronchoscopy, the ease of intubation, the success rate of intubation, and the duration for device removal from the tracheal tube. Methodology A hospital-based descriptive observational study was conducted with 80 patients. An adequately sized Ambu® Aura-i™ was placed after general anesthesia was induced. Following a fiberoptic examination of the view of the glottis through the Ambu® Aura-i™, the trachea was intubated under fiberoptic guidance. The Ambu® Aura-i™ insertion time, glottic view grading, ease of intubation, and time required for fiberoptic-guided intubation were recorded. Also, the time taken to remove the Ambu® Aura-i™ was documented. Results Similar levels of ease were experienced by both groups after inserting the Ambu® Aura-i™, being easy in both group 1 (37/40) and in group 2 (38/40). In group 1, the average time taken to insert the Ambu® Aura-i™ was 13.53±1.91 seconds, while in group 2, it was 13.98±2.4 seconds. The average time required for fiberoptic-guided intubation was found to be 14.95±1.85 seconds in group 1 and 14.15±1.37 seconds in group 2, indicating a statistically negligible variation. Conclusion The low cost of Ambu® Aura-i™, size suitability and availability for almost all age groups, compatibility with MRI machines, and availability in phthalate-free versions contribute to it being a more appealing and useful ventilatory device, as well as an intubation tool for both normal and emergency airway management.

Modified NUTRIC Score as a Predictor of All-cause Mortality in Critically Ill Patients: A Systematic Review and Meta-analysis.

Purpose: The purpose of our meta-analysis was to look at the impact of modified nutrition risk in the critically ill (mNUTRIC) on mortality in patients with critical illness. Materials and methods: Literature relevant to this meta-analysis was searched in PubMed, Web of Science, and Cochrane Library till 26 August 2023. Prospective or retrospective studies, patients >18 years of age, studies that reported on mortality and mNUTRIC (mNUTRIC cut-off score) were included. The QUIPS tool was used to evaluate the risk for bias in prognostic factors. Results: A total of 31 studies on mNUTRIC score, involving 13,271 patients were included. The summary area under the curve (sAUC) of 0.80 (95% CI: 0.76-0.83) illustrates the mNUTRIC score's strong discrimination. The pooled sensitivity was 0.79 (95% CI: 0.74-0.84) and pooled specificity was 0.68 (95% CI: 0.63-0.73). We found no discernible variation in the mNUTRIC's prediction accuracy among cut-off values of <5 and >5 in our subgroup analysis and sAUC values were 0.82 (95% CI: 0.78-0.85) and 0.78 (95% CI: 0.74-0.81), respectively. Conclusion: We observed that mNUTRIC can discriminate between critically ill individuals and predict their mortality. Prospero: CRD42023460292.

Adverse Effects Related to Corticosteroid Use in Sepsis, Acute Respiratory Distress Syndrome, and Community-Acquired Pneumonia: A Systematic Review and Meta-Analysis.

OBJECTIVES: We postulate that corticosteroid-related side effects in critically ill patients are similar across sepsis, acute respiratory distress syndrome (ARDS), and community-acquired pneumonia (CAP). By pooling data across all trials that have examined corticosteroids in these three acute conditions, we aim to examine the side effects of corticosteroid use in critical illness. DATA SOURCES: We performed a comprehensive search of MEDLINE, Embase, Centers for Disease Control and Prevention library of COVID research, CINAHL, and Cochrane center for trials. STUDY SELECTION: We included randomized controlled trials (RCTs) that compared corticosteroids to no corticosteroids or placebo in patients with sepsis, ARDS, and CAP. DATA EXTRACTION: We summarized data addressing the most described side effects of corticosteroid use in critical care: gastrointestinal bleeding, hyperglycemia, hypernatremia, superinfections/secondary infections, neuropsychiatric effects, and neuromuscular weakness. DATA SYNTHESIS: We included 47 RCTs (n = 13,893 patients). Corticosteroids probably have no effect on gastrointestinal bleeding (relative risk [RR], 1.08; 95% CI, 0.87-1.34; absolute risk increase [ARI], 0.3%; moderate certainty) or secondary infections (RR, 0.97; 95% CI, 0.89-1.05; absolute risk reduction, 0.5%; moderate certainty) and may have no effect on neuromuscular weakness (RR, 1.22; 95% CI, 1.03-1.45; ARI, 1.4%; low certainty) or neuropsychiatric events (RR, 1.19; 95% CI, 0.82-1.74; ARI, 0.5%; low certainty). Conversely, they increase the risk of hyperglycemia (RR, 1.21; 95% CI, 1.11-1.31; ARI, 5.4%; high certainty) and probably increase the risk of hypernatremia (RR, 1.59; 95% CI, 1.29-1.96; ARI, 2.3%; moderate certainty). CONCLUSIONS: In ARDS, sepsis, and CAP, corticosteroids are associated with hyperglycemia and probably with hypernatremia but likely have no effect on gastrointestinal bleeding or secondary infections. More data examining effects of corticosteroids, particularly on neuropsychiatric outcomes and neuromuscular weakness, would clarify the safety of this class of drugs in critical illness.

Retrospective Analysis of Clinical Characteristics and Outcomes of Pregnant Women with SARS-CoV-2 Infections Admitted to Intensive Care Units in India (Preg-CoV): A Multicenter Study.

Aim: The aim was to examine the outcomes of pregnant women admitted to intensive care unit with coronavirus disease-2019 (COVID-19) infection during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic in India. The primary outcome of the study was maternal mortality at day 30. The secondary outcomes were the intensive care unit (ICU) and hospital length of stay, fetal mortality and preterm delivery. Materials and methods: This was a retrospective multicentric cohort study. Ethical clearance was obtained. All pregnant women of the 15-45-year age admitted to ICUs with SARS-CoV-2 infection during 1st March 2020 to 31st October, 2021 were included. Results: Data were collected from nine centers and for 211 obstetric patients admitted to the ICU with a confirmed diagnosis of COVID-19. They were divided in to two groups as per their SpO2 (saturation of peripheral oxygen) level at admission on room air, that is, normal SpO2 group (SpO2 > 90%) and low SpO2 group (SpO2 < 90%). The mean age was (30.06 ± 4.25) years and the gestational age was 36 ± 8 weeks. The maternal mortality rate was10.53%. The rate of fetal death and preterm delivery was 7.17 and 28.22%, respectively. The average ICU and hospital length of stay (LOS) were 6.35 ± 8.56 and 6.78 ± 6.04 days, respectively. The maternal mortality (6.21 vs 43.48%, p < 0.001), preterm delivery (26.55 vs 52.17%, p = 0.011) and fetal death (5.08 vs 26.09%, p = 0.003) were significantly higher in the low SpO2 group. Conclusion: The overall maternal mortality among critically ill pregnant women affected with COVID-19 infection was 10.53%. The rate of preterm birth and fetal death were 28.22 and 7.17%, respectively. These adverse maternal and fetal outcomes were significantly higher in those admitted with low SpO2 (<90%) at admission compared with those with normal SpO2.

Echocardiographic parameters in COVID-19 patients and their association with ICU mortality: a prospective multicenter observational study.

BACKGROUND: Echocardiography has become an integral part of the management of critically ill patients. It helps to diagnose and treat various conditions. COVID-19 patients can develop cardiac dysfunction. We planned to study the echocardiographic parameters in COVID-19 patients. METHODS: We conducted a prospective observational multicenter study after institutional ethical committee approval. COVID-19 pneumonia patients admitted to the intensive care unit (ICU) were enrolled. The echocardiographic evaluation was done within 24-48 hours of admission. Assessment of the left and right heart with systolic and left ventricular diastolic function evaluation was done. The primary outcome was ICU mortality. The secondary outcomes were the length of ICU stay and duration of mechanical ventilation. RESULTS: Among 573 patients mean age was 57.17 (14.67) with 68.60% being males. On day 1 of ICU, invasive mechanical ventilation was used in 257 (45%) patients. One hundred and forty-eight (25.83%) patients were on vasopressors when echocardiography was performed. Severe left ventricle (LV) systolic dysfunction was seen in 8.7% of patients and had higher odds of mortality [2.48(1.058-5.807), p = 0.037] followed by E and e' with odds ratio of [0.984(0.971-0.998), p = 0.021] and 0.897 (0.805-0.998), p = 0.046], respectively. E/e' indicative of filling pressure of the LV was not found to be significant. Troponin I, E/A, and RV dilatation were similar among survivors and non-survivors. CONCLUSION: Echocardiographic evaluation in COVID-19 patients showed severe LV systolic dysfunction was associated with ICU mortality. E/e' was not found to be significant but lower e' was associated with higher mortality. Trial registration IEC 131/2020, CTRI/2020/06/025858 date 13th June 2020.

The Comparison of Dexmedetomidine to Dexamethasone as Adjuvants to Bupivacaine in Ultrasound-Guided Infraclavicular Brachial Plexus Block in Upper Limb Surgeries.

Background The clinical utility of adjuvants with local anesthesia produces an excellent nerve block with prolonged duration and faster onset. Brachial plexus block is widely used nowadays in patients undergoing upper limb surgery There are several approaches to achieve brachial plexus block such as interscalene, supraclavicular, infraclavicular, and axillary. The objective of this study is to compare the effectiveness of dexamethasone to dexmedetomidine as adjuvants to bupivacaine in patients undergoing ultrasound-guided infraclavicular brachial plexus (USG-ICBP) block. Methods A randomized, prospective, double-blind study was undertaken on the patients posted for upper limb surgeries under ultrasound-guided infraclavicular brachial plexus block. Sixty patients with the American Society of Anesthesiologists (ASA) classes I and II were randomly allocated into two groups. Group A received 25 mL of 0.5% bupivacaine and 1.5 mL (6 mg) of dexamethasone, and group B received 25 mL of 0.5% bupivacaine and 0.75 mL (75 mcg) of dexmedetomidine along with 0.75 mL of 0.9% normal saline (NS). Student's t test or Mann-Whitney test and chi-square test were used for statistical analysis. Results The onset of sensory block was significantly faster in the patients in group B as compared to the patients in group A. In terms of the duration of the block, sensory and motor blocks were maintained for a significantly longer duration in the group A patients as compared to those in group B. Moreover, the duration of postoperative analgesia was significantly longer-lasting in the group A patients. In terms of adverse effects, procedure-related complications such as the failure of the block and inadequate block were comparable across the groups. However, drug-related adverse effects were significantly more common in group B. Conclusion As compared to 75 mcg of dexmedetomidine, the addition of 6 mg of dexamethasone as adjuvant to 25 mL of 0.5% bupivacaine resulted in significantly longer-lasting sensory and motor blocks, postoperative analgesia, and a delayed time for first rescue analgesia without increasing undue adverse effects. Dexmedetomidine use is associated with more sedation as compared to dexamethasone.

A comparison of prophylactic antiemetic therapy with palonosetron and dexamethasone as single-agents or in combination in adult patients undergoing laparoscopic surgery: A randomized trial.

Background: The incidence of postoperative nausea and vomiting (PONV) is quite high after laparoscopic surgeries. This study endeavors to compare the efficacy of the combination of palonosetron and dexamethasone with that of either drug alone in the prevention of PONV in patients undergoing laparoscopic surgeries. Methods: This randomized, parallel-group trial was done on ninety adults of American Society of Anesthesiologists Grade I and II patients aged 18-60 years undergoing laparoscopic surgeries under general anesthesia. The patients were randomly divided into three groups of thirty patients each. Group P (n = 30) received palonosetron 0.075 mg intravenously (iv), Group D (n = 30) received dexamethasone 8 mg iv and Group P + D (n = 30) received palonosetron 0.075 mg and dexamethasone 8 mg iv. The primary outcome was incidence of PONV in 24 h, and the secondary outcome was a number of rescue antiemetics required. To compare the proportions in the groups, unpaired t-test, Mann-Whitney U-test, Chi-square test, or Fisher's exact test was applied. Results: We found that the overall incidence of PONV was 46.7% in Group P, 50% in Group D, and 43.3% in Group P + D during the first 24 h. Rescue antiemetic was required in 27% of the patients in Group P and Group D compared to 23% of the patients in Group P + D and twice in 3% of the patients in Group P, 7% of the patients in Group D, and none in Group P + D which were not significant. Conclusions: The combination therapy of palonosetron plus dexamethasone did not significantly reduce the incidence of PONV when compared with either drug alone.

Serum Lipase Amylase Ratio as an Indicator to Differentiate Alcoholic From Non-alcoholic Acute Pancreatitis: A Systematic Review and Meta-Analysis.

A lipase/amylase (L/A) ratio of more than three may be a tool for differentiating alcoholic pancreatitis from non-alcoholic pancreatitis. We conducted a systematic literature review to identify published studies. A thorough data search of various databases was conducted using keywords. Study quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 survey. Data were extracted under the following headings: country, sample size, baseline characteristics, specificity, and sensitivity of the L/A ratio. Studies were analyzed using a bivariate random-effects model, and the sensitivity and specificity of the L/A ratio were pooled separately. Summary receiver operating characteristic (SROC) curves were plotted using the hierarchical method. A total of nine studies with 1,825 patients were identified for inclusion. SROC showed estimates of the area under the curve to be 0.75 (confidence interval (CI) = 0.71-0.79). Forest plots for sensitivity and specificity showed pooled estimates of sensitivity to be 74% (95% CI = 62-83%) while that of specificity was 63% (95% CI = 47-77%). The pooled diagnostic odds ratio was estimated to be 5 (95% CI = 3-9), the pooled positive likelihood ratio was estimated at 2.0, and the pooled negative likelihood ratio was estimated to be 0.41. We concluded that an L/A ratio of more than 3 has moderate accuracy for the diagnosis of alcoholic pancreatitis.

Three-Way Cell-Based Screening of Antistress Compounds: Identification, Validation, and Relevance to Old-Age-Related Pathologies.

A variety of environmental stress stimuli have been linked to poor quality of life, tissue dysfunctions, and ailments including metabolic disorders, cognitive impairment, and accelerated aging. Oxidative, metal, and hypoxia stresses are largely associated with these phenotypes. Whereas drug development and disease therapeutics have advanced remarkably in last 3 decades, there are still limited options for stress management. Because the latter can effectively decrease the disease burden, we performed cell-based screening of antistress compounds by recruiting 3 chemical models of oxidative (paraquat), metal (cadmium nitrate), or hypoxia (cobalt chloride) stresses. The screening of 70 compounds for their ability to offer protection against oxidative, metal, and hypoxia stresses resulted in the selection of 5 compounds: Withaferin-A (Wi-A), methoxy Withaferin-A (mWi-A), Withanone (Wi-N), triethylene glycol (TEG), and Ashwagandha (Withania somnifera) leaf M2-DMSO extract (M2DM). Molecular assays revealed that whereas stress caused increase in (a) apoptosis, (b) reactive oxygen species accumulation coupled with mitochondrial depolarization, (c) DNA double-strand breaks, and (d) protein aggregation, low nontoxic doses of the selected compounds caused considerable protection. Furthermore, Wi-N, TEG, and their mixture-treated normal human fibroblasts (at young, mature, and senescent stages representing progressively increasing accumulation of stress) showed increase in proliferation. Taken together, these results suggested 3-way (oxidative, metal, and hypoxia) antistress potential of Wi-N and TEG that may be useful for management of environmental and old-age-related pathologies.

Computed tomography severity score as a predictor of disease severity and mortality in COVID-19 patients: A systematic review and meta-analysis.

BACKGROUND: Prediction of outcomes in severe COVID-19 patients using chest computed tomography severity score (CTSS) may enable more effective clinical management and early, timely ICU admission. We conducted a systematic review and meta-analysis to determine the predictive accuracy of the CTSS for disease severity and mortality in severe COVID-19 subjects. METHODS: The electronic databases PubMed, Google Scholar, Web of Science, and the Cochrane Library were searched to find eligible studies that investigated the impact of CTSS on disease severity and mortality in COVID-19 patients between 7 January 2020 and 15 June 2021. Two independent authors looked into the risk of bias using the Quality in Prognosis Studies (QUIPS) tool. RESULTS: Seventeen studies involving 2788 patients reported the predictive value of CTSS for disease severity. The pooled sensitivity, specificity, and summary area under the curve (sAUC) of CTSS were 0.85 (95% CI 0.78-0.90, I2 =83), 0.86 (95% CI 0.76-0.92, I2 =96) and 0.91 (95% CI 0.89-0.94), respectively. Six studies involving 1403 patients reported the predictive values of CTSS for COVID-19 mortality. The pooled sensitivity, specificity, and sAUC of CTSS were 0.77 (95% CI 0.69-0.83, I2 = 41), 0.79 (95% CI 0.72-0.85, I2 = 88), and 0.84 (95% CI 0.81-0.87), respectively. DISCUSSION: Early prediction of prognosis is needed to deliver the better care to patients and stratify them as soon as possible. Because different CTSS thresholds have been reported in various studies, clinicians are still determining whether CTSS thresholds should be used to define disease severity and predict prognosis. CONCLUSION: Early prediction of prognosis is needed to deliver optimal care and timely stratification of patients.  CTSS has strong discriminating power for the prediction of disease severity and mortality in patients with COVID-19.

Preemptive Levetiracetam Decreases Postoperative Pain: A Double-Blind, Randomised, Control Trial.

Background Previously many studies have found the use of anti-epileptic drugs such as pregabalin, carbamazepine, and gabapentin in pain management. In addition, levetiracetam (LEV), an effective anti-epileptic drug, has shown analgesic effects in animal models. We aimed to evaluate the effect of oral LEV as pre-emptive analgesia in patients who underwent laparoscopic cholecystectomy under general anaesthesia and postoperative fentanyl requirements. Material and methods Forty-two patients of the American Society of Anaesthesiologists (ASA) grade I and II of either gender posted for elective laparoscopic cholecystectomy surgery were included in this double-blind, randomised, placebo-controlled study. Patients were divided into two equal groups of 21 each to receive either tablet LEV 500 mg or a matching placebo tablet, given 1 hour before surgery. Postoperative pain was assessed by a visual analogue scale (0-100 mm), where 0 meant no pain and 100, worst pain. In addition, patients received IV fentanyl as rescue analgesia during the first 24 hours of the postoperative period. Results Nineteen patients in the LEV group and 20 in the placebo group completed the study. Patients in the LEV group had significantly lower pain scores at all time intervals except 0 hours and reduced fentanyl consumption postoperatively in the first 24 hours (p<0.05). Side effects were comparable in both groups. Conclusion A single, preoperative dose of oral LEV 500 mg significantly decreases post-surgical pain and fentanyl demand as rescue analgesia in elective laparoscopic cholecystectomy.

Integrated computational and experimental approach for novel anti-leishmanial molecules by targeting Dephospho-coenzyme A kinase.

Coenzyme A acts as a necessary cofactor for many enzymes and is a part of many biochemical processes. One of the critical enzymes involved in Coenzyme A synthesis is Dephospho-coenzyme A-kinase (DPCK). In this study, we have used integrated computational and experimental approaches for promising inhibitors of DPCK using the natural products available in the ZINC database for anti-leishmanial drug development. The top hit compounds chosen after molecular docking were Veratramine, Azulene, Hupehenine, and Hederagenin. The free binding energy of Veratramine, Azulene, Hupehenine, and Hederagenin was estimated. Besides the favourable binding point, the ligands also showed good hydrogen bonding and other interactions with key residues of the enzyme's active site. The natural compounds were also experimentally investigated for their effect on the L. donovani promastigotes and murine macrophage (J774A.1). A good antileishmanial activity by the compounds on the promastigotes was observed as estimated by the MTT assay. The in-vitro experiments revealed that Hupehenine (IC50 = 7.34 ± 0.37 µM) and Veratramine (IC50 = 12.46 ± 2.28 µM) exhibited better inhibition than Hederagenin (IC50 = 23.36 ± 0.54 µM) and Azulene (IC50 = 24.42 ± 3.28 µM). This work has identified novel anti-leishmanial molecules possibly acting through the inhibition of DPCK.

Tracking collective emotions in 16 countries during COVID-19: a novel methodology for identifying major emotional events using Twitter.

Using messages posted on Twitter, this study develops a new approach to estimating collective emotions (CEs) within countries. It applies time series methodology to develop and demonstrate a novel application of CEs to identify emotional events that are significant at the societal level. The study analyzes over 200 million words from over 10 million Twitter messages posted in 16 countries during the first 120 days of the COVID-19 pandemic. Daily levels of collective anxiety and positive emotions were estimated using Linguistic Inquiry and Word Count's (LIWC) psychologically validated lexicon. The time series estimates of the two collective emotions were analyzed for structural breaks, which mark a significant change in a series due to an external shock. External shocks to collective emotions come from events that are of shared emotional relevance, and this study develops a new approach to identifying them. In the COVID-19 Twitter posts used in the study, analysis of structural breaks showed that in all 16 countries, a reduction in collective anxiety and an increase in positive emotions followed the WHO's declaration of COVID-19 as a global pandemic. Announcements of economic support packages and social restrictions also had similar impacts in some countries. This indicates that the reduction of uncertainty around the evolving COVID-19 situation had a positive emotional impact on people in all the countries in the study. The study contributes to the field of CEs and applied research in collective psychological phenomena.

Role of Mycobacterium indicus pranii in clinical outcomes in patients with sepsis: A systematic review and meta-analysis of randomised controlled trials.

Background and Aims: Sepsis-induced immunosuppression appears to be reversible with immunomodulatory drugs. Mycobacterium indicus pranii (MIP) stimulates the Th1 type of immune response. This systematic review and meta-analysis of randomised controlled trials (RCTs) was aimed to find out if MIP is effective at improving clinical outcomes in sepsis patients. Methods: The databases (PubMed, Google Scholar, Web of Science, and Cochrane Library), along with preprint servers until June 2023, were searched. The methodology was evaluated using the 'Cochrane Collaboration risk of bias-2 tool' for RCT. The study included patients more than 18 years of age with sepsis within 48 h of first organ dysfunction. The primary outcome was 28-day mortality, and secondary outcomes were the length of stay in the intensive care unit (ICU), days on vasopressor support, ventilator-associated pneumonia (VAP), secondary infections, catheter-related bloodstream infections (CRBSI), and the delta sequential organ failure assessment (SOFA) score. Results: The meta-analysis included two studies with 252 participants. In a pooled analysis, mortality in the MIP group was 43% lower than in the control (RR: 0.57, 95%CI: 0.33-1); however, this difference was statistically not significant. We observed the days on a vasopressor day (standardised mean difference [SMD]: 0.38; 95%CI: -1.20 to 0.44), length of ICU stay (SMD: 0.46; 95%CI: -1.44 to 0.51), secondary infection (RR: 0.75; 95%CI: 0.19-3.01), VAP (RR: 0.6; 95%CI: 0.28-1.56), CRBSI (RR: 0.97, 95%CI: 0.14-6.98), delta SOFA score (SMD: 0.88, 95%CI: -1.66 to - 0.10) between the two groups. Conclusions: Our findings observed preliminary evidence in the trends for a positive association of MIP with better outcomes in sepsis patients.

Comparison of analgesic effects of pericapsular nerve group block and fascia iliaca compartment block during hip arthroplasty: A systematic review and meta-analysis of randomised controlled trials.

Background and Aims: Postoperative pain for patients having hip arthroplasty ranges from moderate to severe. Many regional anaesthesia procedures treat postoperative pain to improve functional ability and quality of life. Evidence comparing the analgesic effects of the pericapsular nerve group (PENG) block and fascia iliaca compartment block (FICB) remains unclear. The analgesic efficacies of PENG and FICB in hip arthroplasty were compared to determine which technique is associated with superior analgesia. Methods: The electronic databases (PubMed, Cochrane Library, Google Scholar and Web of Sciences) were searched for published randomised controlled trials (RCTs) till 5 April 2023 comparing PENG block vs. FICB following hip arthroplasty. The primary outcome was pain scores [numerical rating scale (NRS) or visual analogue scale (VAS)] between 0 and 10 at rest and during movement at 24 h. Secondary outcomes included pain scores at rest and during movement within 30 min, at 6 h and 12 h, time to first rescue analgesia and cumulative postoperative opioid use in 24 h. We assessed the risk of bias using the Cochrane Collaboration Risk-of-Bias 2 tool. Using Grading of Recommendations Assessment, Development, and Evaluation (GRADE), the certainty of the evidence was assessed. Subgroup analysis was performed to explore the source of heterogeneity. Results: We included 12 RCTs examining 644 patients. Pain scores at rest at 24 h (standardised mean differences (SMDs): 0.17; 95% confidence interval (CI): -0.90 to 1.23; P = 0.76, moderate certainty) and during movement at 24 h (SMD: -0.58, 95% CI: -1.53 to 0.38, P = 0.24, moderate certainty) were not different in both PENG block and FICB. Pain scores at rest and during movement within 30 min may be lower with PENG block than FICB. However, the pain score at rest and during movement at 6 h and the time to first rescue analgesia were not different between the two treatment arms. The mean opioid consumption in oral morphine equivalents (mg) in 24 h may be lower with PENG than FICB. Conclusion: We observed no difference between the PENG block and the FICB at 24 h for pain at rest and movement with a moderate degree of certainty. However, PENG block showed improved analgesia within 30 min at rest and during movement, and reduce postoperative opioid consumption in 24 h with moderate certainty of evidence. Further large-scale and high-quality RCTs are required to supplement the present findings.

Study of cases of puerperal sepsis, its socio-demographic factors, bacterial isolates, and antibiotic sensitivity pattern.

Objective: Due to the lack of resources for culture and antibiotic susceptibility testing in most underdeveloped countries, puerperal sepsis is treated empirically with a wide range of antibiotics. Empirical treatment, on the other hand, does not ensure treatment effectiveness and may even contribute to antibiotic resistance. So, we studied cases of puerperal sepsis, its socio-demographic factors, bacterial isolates, and antibiotic sensitivity in a tertiary health center. Material and Methods: This was a cross-sectional study conducted at the obstetrics and gynecology department of a tertiary health center in India from April 2019 to September 2020. During this time, all patients with sepsis who met the criteria for inclusion were included. After granting an informed written consent, the subjects were registered on a pre-designed proforma. Results: There were 2,049 obstetrical admissions throughout this period, with 106 (5.1%) of these having puerperal sepsis. The majority of these women (58.7%) were between the ages of 21 and 30, were multiparous (96.5%), and unbooked. Fever 104 (98.1%) was the most prevalent clinical characteristic, whereas wound gape was the most common consequence (47.1%). Klebsiella aerogens was the most common organism found in various cultures. Many organisms were shown to be multidrug-resistant and sensitive to gentamycin and amikacin. Conclusion: Klebsiella aerogens wasthe most common cause of puerperal sepsis in this investigation. Because the causal agents of puerperal sepsis and their antibiotic sensitivity patterns change over time, positive blood culture and antibiotic susceptibility of the isolates are the best guides for selecting the optimum antimicrobial therapy for treating sepsis.

Epidemiology and ventilation characteristics of confirmed cases of severe COVID-19 pneumonia admitted in intensive care unit (EPIC19): A multicentre observational study.

Background and Aims: Coronavirus disease (COVID)-19 has spread across the globe. For a country like India with limited resources and a high population, it is worth knowing how these patients were managed. This prospective study was aimed to evaluate the patient characteristics and risk factors associated with mortality. Methods: The study was conducted from 15 June 2020 to 31 December 2020 in four centres across India. Patients above 18 years of age admitted in the intensive care unit (ICU) with severe COVID-19 pneumonia were included. Details of oxygen therapy and ventilator characteristics were collected for seven days. Results: Of 667 patients included in the study, the average age was 57 (standard deviation (SD) = 15) years and 70.46% were male. The ICU mortality was 60%. Acute physiology, age and chronic health evaluation (APACHE II) score was 29.8 (SD = 6.1). Among various significant risk factors, the need for invasive ventilator support on day 1 [odds ratio (OR): 3.11, 95% confidence interval (CI) (1.91-5.08)] and the development of arrhythmia [OR 3.85 CI (1.69,8.77) confidence interval (CI) (1.69, 8.77)] had higher odds of mortality. PF ratio [partial pressure of arterial oxygen/fraction of inspired oxygen] was 109.31 (77.79-187.26), maximum positive end-expiratory pressure was 10.29 (3.5) cmH2O, driving pressure was 18.22 (6.16) cmH2O, static compliance was 24.20 (8.57) ml/cmH2O and dynamic compliance was 17.55 (5.18) ml/cmH2O on day 1. Proning was used in 67 (22.41%) intubated patients and 44 (11.96%) awake patients. Conclusion: In this cohort of patients, ICU mortality was 60%. The reason for higher mortality could be the severity of illness as suggested by day 1 PF ratio and APACHE II score.
