Safety and efficacy of resmetirom in the treatment of patients with non-alcoholic steatohepatitis and liver fibrosis: a systematic review and meta-analysis.

Introduction: Non-alcoholic fatty liver disease (NAFLD), spanning from non-alcoholic steatohepatitis (NASH) to liver fibrosis, poses a global health challenge amid rising obesity and metabolic syndrome rates. Effective pharmacological treatments for NASH and liver fibrosis are limited. Objective: This study systematically reviews and meta-analyzes the safety and efficacy of resmetirom, a selective thyroid hormone receptor-ß agonist, in NASH and liver fibrosis treatment. By analyzing data from clinical trials, we aim to offer evidence-based recommendations for resmetirom's use in managing these conditions and identify avenues for future research. Methods: Electronic databases (PubMed, Scopus, Science Direct, Google Scholar, ClinicalTrials.gov, and Cochrane CENTRAL) were systematically searched, supplemented by manual screening of relevant sources. Only English-language randomized controlled trials were included. Data extraction, risk of bias assessment, pooled analyses, and meta-regression were performed. Results: Three randomized controlled trials involving 2231 participants were analyzed. Resmetirom demonstrated significant reductions in hepatic fat fraction [standardized mean difference (SMD) -4.61, 95% CI -6.77 to -2.44, P < 0.0001], NASH resolution without worsening fibrosis [risk ratio (RR) 2.51, 95% CI 1.74-3.64, P = 0.00001), and liver fibrosis improvement (RR 2.31, 95% CI 1.20-4.44, P = 0.01). Secondary outcomes showed significant improvements in lipid profiles, liver enzymes, and NASH biomarkers with resmetirom treatment. Meta-regression revealed associations between covariates and primary outcomes. Conclusion: Resmetirom exhibits promising efficacy in reducing hepatic fat, improving NASH resolution, and ameliorating liver fibrosis with a favorable safety profile. Further research is warranted to validate findings and optimize therapeutic strategies for NASH and liver fibrosis management.

Ferric carboxymaltose for iron deficiency in patients with heart failure: a systematic review and meta-analysis.

Aim: Iron deficiency (ID) is associated with heart failure (HF) in a considerable proportion of patients. To improve the quality of life, lower the frequency of hospitalizations, and lower mortality rates of chronic HF patients (HF), this meta-analysis will look into the role of iron supplementation using ferric carboxymaltose (FCM). Methods & results: From inception until 1 October 2023, we conducted a thorough literature search of electronic databases for peer-reviewed publications. Around 5229 HF patients were included, of which 2691 received FCM while 2538 received placebo. Conclusion: FCM reduces HF-related hospitalizations but doesn't improve overall or cardiovascular mortality in those with HF and ID. The overall results support FCM's role in managing iron deficiency in heart failure.

Heart failure (HF) patients often suffer from iron deficiency (ID), worsening their symptoms and quality of life. Intravenous iron therapy, like ferric carboxymaltose (FCM), has been studied for its benefits in HF. This meta-analysis looked at existing research and found that FCM treatment reduced hospitalizations for HF but didn't significantly impact overall mortality. Although FCM improves patients' lives, more research is needed to understand its long-term effects fully. This study highlights the importance of addressing ID in HF management and supports FCM therapy as a beneficial option for HF patients.

The Fe-MAN Challenge: Ferrates-Microkinetic Assessment of Numerical Quantum Chemistry.

Organometallic species, such as organoferrate ions, are prototypical nucleophiles prone to reacting with a wide range of electrophiles, including proton donors. In solution, the operation of dynamic equilibria and the simultaneous presence of several organometallic species severely complicate the analysis of these fundamentally important reactions. This can be overcome by gas-phase experiments on mass-selected ions, which allow for the determination of the microscopic reactivity of the target species. In this contribution, we focus on the reactivity of a series of trisarylferrate complexes toward 2,2,2-trifluoroethanol and 2,2-difluoroethanol. By means of mass-spectrometric measurements, we determined the experimental bimolecular rate constants kexp of the gas-phase protolysis reactions of the trisarylferrate anions FePh3- and FeMes3- with the aforementioned acids. Based on these experiments, we carried out a dual blind challenge, inviting theoretical groups to submit their best predictions for the activation barriers and/or theoretical rate constants ktheo. This provides a unique opportunity to evaluate different computational protocols under minimal bias and sets the stage for further benchmarking of quantum chemical methods and data-driven approaches in the future.

Evaluating the efficacy and safety of weekly Insulin Icodec vs. Daily Insulin Glargine in type 2 Diabetes Mellitus: a systematic review and meta-analysis.

Introduction: Various insulin therapies for Diabetes Mellitus offer different benefits while having potential risks. We aim to compare Insulin Icodec, a novel Insulin analogue with the ease of once-weekly administration, to the once-daily Insulin Glargine U100 regarding glycemic control and safety profile. Methods: We performed a systematic literature search of electronic databases for peer-reviewed articles from inception until September 1 2023. Results: A total of 2215 type 2 diabetic patients were included, of which 1209 received Insulin Icodec and1048 recieved Insulin Glargine U100. In terms of glycemic control, Insulin Icodec showed a significantly longer time in the target glucose range (MD: 0.304, CI: 0.069, P = 0.000) and a more significant reduction in HbA1c (MD: -0.154, CI: 0.003, P = 0.005) compared to Insulin Glargine U100. Fasting Plasma Glucose did not differ significantly. Insulin Icodec led to a more significant increase in body weight (MD: 0.161 kg, P = 0.029), while Insulin Glargine required a higher insulin dose (MD: 1.920 IU, P = 0.000). Regarding safety, the two groups had no significant differences in hypoglycemic events or adverse outcomes. Conclusion: Once-weekly Insulin Icodec demonstrates superior glycemic control with a reduced HbA1c compared to Once-Daily Insulin Glargine U100 while maintaining similar safety profiles.

Evaluating the effectiveness and safety of various Tirzepatide dosages in the management of Type 2 diabetes mellitus: a network meta-analysis of randomized controlled trials.

Purpose: Excess body fat, insulin resistance, and abnormal lipid levels signal type 2 diabetes mellitus (DM2). Globally, 536.6 million people suffer from DM2, projected to rise to 783.2 million by 2045. Obesity fuels insulin resistance and DM2 development, with weight loss significantly improving glycemic control. Titrzepatide (TZP), a dual GIP and GLP-1 receptor agonist, proves highly effective in controlling hyperglycemia, stimulating insulin secretion, and promoting weight loss. TZP, holds promise as a treatment for DM2, surpassing insulin and GLP-1. The study aimed to meticulously assess the safety and efficacy of various doses, offering insights into optimal therapeutic strategies for managing DM2. Methods: This study aimed to comprehensively evaluate the safety and efficacy of TZP in treating DM2. The primary focus of the inclusion criteria was on trials comparing TZP with a placebo until November 23, 2023, excluding patients with certain comorbidities. Data extraction included key parameters, and outcomes were assessed for HbA1c levels, weight changes, fasting serum glucose levels, and various adverse events. Quality assessment utilized the Cochrane Collaboration's risk-of-bias tool, and a network meta-analysis explored outcomes across different TZP dosages. Results: This meta-analysis systematically reviewed ten studies on TZP for DM2. Results revealed significant reductions in HbA1c with TZP 10 mg (19%) and TZP 15 mg (31%) compared to TZP 5 mg (MD: -0.19 and MD: -0.32, respectively). Additionally, weight reduction was notable for TZP 10 mg (MD: -1.96) and TZP 15 mg (MD: -3.31). Fasting serum glucose showed improvement with TZP 15 mg (MD:-6.71). Gastrointestinal events increased with higher doses, yet without statistical significance. Death, nausea, diarrhea, vomiting, dyspepsia, decreased appetite, injection site reaction, hypoglycemia, treatment discontinuation, and serious adverse events showed no significant differences across doses. Conclusion: TZP effectively lowers HbA1c and induces weight loss across its three doses for type 2 diabetes management. The higher dose (15 mg) significantly reduces fasting serum glucose, with increased adverse events observed at higher doses. Dose-specific patterns for adverse effects emphasize the need to balance therapeutic benefits and risks. Further research is crucial for refining clinical applications and understanding TZP's role in DM2 management across doses.

Comparing equiosmolar hypertonic saline and mannitol for achieving brain relaxation in elective craniotomy patients: A systematic review and meta-analysis.

Background: This study strives to provide a current and thorough assessment of the comparative efficacy and safety between equiosmolar quantities of hypertonic saline (HS) and mannitol in facilitating brain relaxation for patients undergoing elective craniotomies. Methods: This systematic review and meta-analysis, following preferred reporting items for systematic reviews and meta-analyses guidelines, compared the efficacy and safety of equiosmolar concentrations of mannitol and HS in elective craniotomies. PubMed, Scopus, Cochrane Library, ScienceDirect, and Proquest databases were searched using keywords related to mannitol, HS, and craniotomy. Results were analyzed through a random-effects model using Mantel-Haenszel risk ratio and standard mean difference. P < 0.05 was considered significant. Results: Thirteen randomized controlled trials encompassing 965 patients (516 in the HS group and 448 in the mannitol group) were analyzed. The quality of studies was moderate-to-high, and no significant publication bias was observed. The primary outcome, brain relaxation, favored HS over mannitol without significant heterogeneity. Mannitol was associated with increased urine output compared to HS, irrespective of dose, with high heterogeneity. HS was linked to significantly reduced fluid input, confirmed by subgroup analysis with lower heterogeneity. No significant difference was found in serum osmolality between the two agents. Serum sodium (Na+) levels favored HS, whereas arterial blood Na+ levels also favored HS despite considerable heterogeneity. Maximum mean arterial pressure was higher with HS, but it displayed significant heterogeneity. Maximum central venous pressure showed no significant difference between the two agents, with moderate heterogeneity. Conclusion: HS appears more effective than mannitol in achieving brain relaxation, and it may offer advantages in fluid management and Na+ balance. Clinicians should consider these findings when selecting hyperosmotic agents for neurosurgical procedures. Further research is needed to address heterogeneity in certain outcomes and guide clinical practice.

With a general incidence rate of 5.81 per 100000, gliomas pose a significant global concern, necessitating advancements in treatment techniques to reduce mortality and morbidity. This review places a particular focus on immunotherapies, discussing promising agents such as Zotiraciclib and Lerapolturev. Zotiraciclib, a CDK9 inhibitor, has demonstrated efficacy in glioblastoma treatment in preclinical and clinical studies, showing its potential as a therapeutic breakthrough. Lerapolturev, a viral immunotherapy, induces inflammation in glioblastoma and displays positive outcomes in both adult and pediatric patients. Exploration of immunotherapy extends to Pembrolizumab, Nivolumab, and Entrectinib, revealing the challenges and variabilities in patient responses. Despite promising preclinical data, the monoclonal antibody Depatuxizumab has proven ineffective in glioblastoma treatment, emphasizing the critical need to understand resistance mechanisms. The review also covers the success of radiation therapy in pediatric LGG, with evolving techniques, such as proton therapy, showing potential improvements in patient quality of life. Surgical treatment is discussed in the context of achieving a balance between preserving the patient's quality of life and attaining gross total resection, with the extent of surgical resection significantly influencing the survival outcomes. In addition to advancements in cancer vaccine development, this review highlights the evolving landscape of LGG treatment, emphasizing a shift toward personalized and targeted therapies. Ongoing research is essential for refining strategies and enhancing outcomes in the management of LGG.

Association between depression and stroke risk in adults: a systematic review and meta-analysis.

Introduction: Stroke is a significant global health concern, and numerous studies have established a link between depression and an increased risk of stroke. While many investigations explore this link, some overlook its long-term effects. Depression may elevate stroke risk through physiological pathways involving nervous system changes and inflammation. This systematic review and meta-analysis aimed to assess the association between depression and stroke. Methodology: We conducted a comprehensive search of electronic databases (PubMed, Embase, Scopus, and PsycINFO) from inception to 9 April 2023, following the Preferred Reporting Items for Systemic Review and Meta-analysis (PRISMA) and Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines. We included all articles assessing the association between different stroke types and depression, excluding post-stroke depression. Two investigators independently extracted data and assessed quality using the Newcastle-Ottawa Scale and Cochrane Risk of Bias tool, utilizing a random-effects model for data synthesis. The primary outcome was the association of depression with stroke, with a secondary focus on the association of antidepressants with stroke. Results: The initial search yielded 10,091 articles, and 44 studies were included in the meta-analysis. The pooled analysis revealed a significant association between depression and stroke risk, with an overall hazard ratio of 1.41 (95% CI 1.32, 1.50; p < 0.00001), indicating a moderately positive effect size. Subgroup analyses showed consistent associations with ischemic stroke (HR = 1.30, 95% CI 1.13, 1.50; p = 0.007), fatal stroke (HR = 1.39, 95% CI 1.24, 1.55; p < 0.000001), and hemorrhagic stroke (HR = 1.33, 95% CI 1.01, 1.76; p = 0.04). The use of antidepressants was associated with an elevated risk of stroke (HR = 1.28, 95% CI 1.05, 1.55; p = 0.01). Conclusion and relevance: This meta-analysis indicates that depression moderately raises the risk of stroke. Given the severe consequences of stroke in individuals with depression, early detection and intervention should be prioritized to prevent it. Systematic review registration: Prospero (CRD42023472136).

Knowledge, Attitude, and Perception of Passive Smoking Among Medical and Dental Students of Karachi: A Survey-Based Study.

Background: Passive smoking, the involuntary inhalation of tobacco smoke, poses significant health risks; however, its prevalence and impact on medical and dental students in Karachi, Pakistan, remain understudied. Therefore, this research aims to understand the knowledge, attitudes, and practices (KAP) regarding passive smoking among medical and dental students and will help shed light on their awareness, perceptions, and behaviours regarding this public health concern. Methods: A cross-sectional study was conducted over 3 months, involving 378 medical and dental students (303 medical and 75 dental students)from various universities in Karachi. Participants completed a questionnaire to gather information on demographics, awareness of passive smoking, perceptions of its health effects, and actions taken in response to exposure. Results: The majority of participants demonstrated awareness of passive smoking 320 (84.7%) and believed that it was essentially linked to active smoking 320 (84.7%). Cigarette smoke was identified as the primary contributor to passive smoking 345 (91.3%). A significant proportion of participants believed that children and pregnant women exposed to passive smoking had elevated health risks. In areas where smoking is not permissible, less than half of the participants 173 (45.8%) reminded smokers about the smoking regulations, and a few even referred smokers for counselling 141 (37.3%). Males are usually indifferent to smokers around them, whereas females are found uncomfortable with smoking in their surroundings. Conclusion: In conclusion, our study highlights the persistent prevalence of passive smoking among medical and dental students in Pakistan. Enforcing strict tobacco control policies, integrating passive smoking education into medical curricula, and improving communication strategies for smoking cessation interventions are crucial steps towards creating smoke-free environments and healthier lifestyles nationwide. Despite awareness among medical and dental students about the dangers of cigarette smoking, their reluctance to urge regular smokers to quit underscores the need for improved communication between smokers and non-smokers to foster a cleaner and hazard-free environment.

The Effects of Chiropractic Spinal Adjustment on EEG in Adults with Alzheimer's and Parkinson's Disease: A Pilot Randomised Cross-over Trial.

OBJECTIVES: In this study, we explored the effects of chiropractic spinal adjustments on resting-state electroencephalography (EEG) recordings and early somatosensory evoked potentials (SEPs) in Alzheimer's and Parkinson's disease. METHODS: In this randomized cross-over study, 14 adults with Alzheimer's disease (average age 67 ± 6 years, 2 females:12 males) and 14 adults with Parkinson's disease (average age 62 ± 11 years, 1 female:13 males) participated. The participants underwent chiropractic spinal adjustments and a control (sham) intervention in a randomized order, with a minimum of one week between each intervention. EEG was recorded before and after each intervention, both during rest and stimulation of the right median nerve. The power-spectra was calculated for resting-state EEG, and the amplitude of the N30 peak was assessed for the SEPs. The source localization was performed on the power-spectra of resting-state EEG and the N30 SEP peak. RESULTS: Chiropractic spinal adjustment significantly reduced the N30 peak in individuals with Alzheimer's by 15% (p = 0.027). While other outcomes did not reach significance, resting-state EEG showed an increase in absolute power in all frequency bands after chiropractic spinal adjustments in individuals with Alzheimer's and Parkinson's disease. The findings revealed a notable enhancement in connectivity within the Default Mode Network (DMN) at the alpha, beta, and theta frequency bands among individuals undergoing chiropractic adjustments. CONCLUSIONS: We found that it is feasible to record EEG/SEP in individuals with Alzheimer's and Parkinson's disease. Additionally, a single session of chiropractic spinal adjustment reduced the somatosensory evoked N30 potential and enhancement in connectivity within the DMN at the alpha, beta, and theta frequency bands in individuals with Alzheimer's disease. Future studies may require a larger sample size to estimate the effects of chiropractic spinal adjustment on brain activity. Given the preliminary nature of our findings, caution is warranted when considering the clinical implications. CLINICAL TRIAL REGISTRATION: The study was registered by the Australian New Zealand Clinical Trials Registry (registration number ACTRN12618001217291 and 12618001218280).

Neurosurgical Malpractice Litigation: A Systematic Review and Meta-Analysis.

BACKGROUND: Neurosurgery has 1 of the highest risks for medical malpractice claims. We reviewed the factors associated with neurosurgical malpractice claims and litigation in the United States and reported the outcomes through a systematic review of the literature. METHODS: We conducted a systematic review of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines using the Medline, Embase, Cochrane, PubMed, and Google Scholar databases. We sought to identify pertinent studies containing information about medical malpractice claims and outcomes involving neurosurgeons in the United States. RESULTS: We identified 15 retrospective studies spanning from 2002 to 2023 that reviewed over 7890 malpractice claims involving practicing neurosurgeons in the United States. Disparities were evident in neurosurgical litigation, with 474 cases linked to brain-related surgeries and a larger proportion, 1926 cases, tied to spine surgeries. The most commonly filed claims were intraprocedural errors (37.4%), delayed diagnoses (32.1%), and failure to treat (28.8%). Less frequently filed claims included misdiagnosis or choice of incorrect procedure (18.4%), occurrence of death (17.3%), test misinterpretation (14.4%), failure to appropriately refer patients for evaluation/treatment (14.3%), unnecessary surgical procedures (13.3%), and lack of informed consent (8.3%). The defendant was favored in 44.3% of claims, while in 31.3% of lawsuits were dropped, 17.7% of verdicts favored the plaintiff, and 16.6% reached an out of court settlement. Only 3.5% of lawsuits found both parties liable. CONCLUSION: Neurosurgery is a high-risk specialty with 1 of the highest rates of malpractice claims. Spine claims had a significantly higher rate of filed malpractice claims, while cranial malpractice claims were associated with higher litigation compensation. Predictably, spinal cord injuries play a crucial role in predicting litigation. Importantly, nonsurgical treatments are also a common source of liability in neurosurgical practice.

Histotripsy: an innovative approach for minimally invasive tumour and disease treatment.

Histotripsy is a noninvasive medical technique that uses high-intensity focused ultrasound (HIFU) to treat liver tumours. The two main histotripsy methods are boiling histotripsy and cavitation cloud histotripsy. Boiling histotripsy uses prolonged ultrasound pulses to create small boiling bubbles in the tissue, which leads to the breakdown of the tissue into smaller subcellular fragments. Cavitation cloud histotripsy uses the ultrasonic cavitation effect to disintegrate target tissue into precisely defined liquefied lesions. Both methods show similar treatment effectiveness; however, boiling histotripsy ensures treatment stability by producing a stable boiling bubble with each pulse. The therapeutic effect is ascribed to mechanical damage at the subcellular level rather than thermal damage. This article discusses the mechanisms, treatment parameters, and potential of histotripsy as a minimally invasive procedure that provides precise and controlled subcellular damage.

Unraveling disparities: Probing gender, race, and geographic inequities in pulmonary heart disease mortality in the United States: An extensive longitudinal examination (1999-2020) leveraging CDC WONDER data.

This comprehensive study delves into the epidemiological landscape of Pulmonary Heart Disease (PHD) mortality in the United States from 1999 to 2020, leveraging the extensive CDC WONDER database. PHD encompasses conditions affecting the right side of the heart due to lung disorders or elevated pressure in the pulmonary arteries, including pulmonary hypertension, pulmonary embolism, and chronic thromboembolic pulmonary hypertension (CTEPH). Analyzing data from death certificates, demographic characteristics, and geographical segmentation, significant trends emerge. The age-adjusted mortality rates (AAMRs) for PHD-related deaths show a fluctuating pattern, initially decreasing from 1999 to 2006, followed by a steady increase until 2020. Male patients consistently exhibit higher AAMRs than females, with notable disparities observed among racial/ethnic groups and geographic regions. Non-hispanic (NH) Black or African American individuals, residents of specific states like Colorado and the District of Columbia, and those in the Midwest region demonstrate elevated AAMRs. Furthermore, nonmetropolitan areas consistently manifest higher AAMRs than metropolitan areas. These findings underscore the urgent need for intensified prevention and treatment strategies to address the rising mortality associated with PHD, particularly among vulnerable populations. Insights from this study offer valuable guidance for public health initiatives aimed at reducing PHD-related mortality and improving outcomes nationwide.

Evaluation of Storage Conditions and the Effect on DNA from Forensic Evidence Objects Retrieved from Lake Water.

DNA analysis of traces from commonly found objects like knives, smartphones, tapes and garbage bags related to crime in aquatic environments is challenging for forensic DNA laboratories. The amount of recovered DNA may be affected by the water environment, time in the water, method for recovery, transport and storage routines of the objects before the objects arrive in the laboratory. The present study evaluated the effect of four storage conditions on the DNA retrieved from bloodstains, touch DNA, fingerprints and hairs, initially deposited on knives, smartphones, packing tapes, duct tapes and garbage bags, and submerged in lake water for three time periods. After retrieval, the objects were stored either through air-drying at room temperature, freezing at -30 °C, in nitrogen gas or in lake water. The results showed that the submersion time strongly influenced the amount and degradation of DNA, especially after the longest submersion time (21 days). A significant variation was observed in success for STR profiling, while mtDNA profiling was less affected by the submersion time interval and storage conditions. This study illustrates that retrieval from water as soon as possible and immediate storage through air-drying or freezing before DNA analysis is beneficial for the outcome of DNA profiling in crime scene investigations.

Bridging drug discovery through hierarchical subtractive genomics against asd, trpG, and secY of pneumonia causing MDR Staphylococcus aureus.

Staphylococcus aureus (S. aureus) is an opportunistic gram-positive, non-motile, and non-sporulating bacteria that induces pneumonia, a provocative lung infection affecting mainly the terminal bronchioles and the small air sacs known as alveoli. Recently, it has developed antibiotic resistance to the available consortium as per the WHO reports; thereby, novel remedial targets and resilient medications to forestall and cure this illness are desperately needed. Here, using pan-genomics, a total of 1,387 core proteins were identified. Subtractive proteome analyses further identified 12 proteins that are vital for bacteria. One membrane protein (secY) and two cytoplasmic proteins (asd and trpG) were chosen as possible therapeutic targets concerning minimum % host identity, essentiality, and other cutoff values, such as high resistance in the MDR S. aureus. The UniProt AA sequences of the selected targets were modelled and docked against 3 drug-like chemical libraries. The top-ranked compounds i.e., ZINC82049692, ZINC85492658 and 3a of Isosteviol derivative for Aspartate-semialdehyde dehydrogenase (asd); ZINC38222743, ZINC70455378, and 5 m Isosteviol derivative for Anthranilate synthase component II (trpG); and finally, ZINC72292296, ZINC85632684, and 7 m Isosteviol derivative for Protein translocase subunit secY (secY), were further subjected to molecular dynamics studies for thermodynamic stability and energy calculation. Our study proposes new therapeutic targets in S. aureus, some of which have previously been reported in other pathogenic microorganisms. Owing to further experimental validation, we anticipate that the adapted methodology and the predicted results in this work could make major contributions towards novel drug discovery and their targets in S. aureus caused pneumonia.

The Prevention of Seroma Formation Following Modified Radical Mastectomy by Intravenous Hydrocortisone Injection.

Introduction Seroma formation is the most common complication after modified radical mastectomy (MRM). It leads to increased pain and discomfort, potentially prolonging morbidity and treatment. Various treatment modalities are being used to decrease the incidence of seroma formation. The objective of this study was to compare intravenous hydrocortisone injection versus placebo in patients undergoing MRM in terms of frequency of post-operative seroma formation. Methods This randomized, double-blinded, placebo-controlled study was conducted at Surgical Unit-I, Holy Family Hospital, Rawalpindi, Pakistan from January 2021 to December 2021. A total of 152 female patients were randomly assigned to each of the study and placebo groups. Group I patients received 100 mg of hydrocortisone intravenously while group II patients received one ml of 0.9% normal saline intravenously prior to induction of general anesthesia for MRM. The incidence of seroma formation after 10 days of MRM and total drain volume till their removal was measured in all patients. Results The mean age was 48.42±10.15 in Group I, while it was 47.67±10.75 in Group II. Mean drain output till removal was 99.14±31.01 ml in the hydrocortisone group and 177.57±63.37 ml in the placebo group. Forty-eight patients developed seroma (31.58%), of whom nine received intravenous hydrocortisone and 39 received normal saline (P=0.000). Conclusion Intravenous hydrocortisone is effective in terms of frequency of post-operative seroma formation as compared to placebo in patients undergoing MRM.

Surgical strategies in acute subdural hematoma: a meta-analysis of decompressive craniectomy vs. craniotomy.

OBJECTIVE: Acute subdural hematoma (ASDH) stands as a significant contributor to morbidity after severe traumatic brain injuries (TBI). The primary treatment approach for patients experiencing progressive neurological deficits or notable mass effects is the surgical removal of the hematoma, which can be achieved through craniotomy (CO) or decompressive craniectomy (DC). Nevertheless, the choice between these two procedures remains a subject of ongoing debate and controversy. MATERIALS AND METHODS: We conducted a comprehensive literature review, utilizing prominent online databases and manually searching references related to craniotomy and craniectomy for subdural hematoma evacuation up to November 2023. Our analysis focused on outcome variables such as the presence of residual subdural hematoma, the need for revision procedures, and overall clinical outcomes. RESULTS: We included a total of 11 comparative studies in our analysis, encompassing 4269 patients, with 2979 undergoing craniotomy and 1290 undergoing craniectomy, meeting the inclusion criteria. Patients who underwent craniectomy displayed significantly lower scores on the Glasgow Coma Scale (GCS) during their initial presentation. Following surgery, the DC group exhibited a significantly reduced rate of residual subdural (P = 0.009). Additionally, the likelihood of a poor outcome during follow-up was lower in the CO group. Likewise, the mortality rate was lower in the CO group compared to the craniectomy group (OR 0.63, 95% CI 0.41-0.98, I2 = 84%, P = 0.04). CONCLUSION: Our study found that CO was associated with more favorable outcomes in terms of mortality, reoperation rate, and functional outcome while DC was associated with less likelihood of residual subdural hematoma. Upon further investigation of patient characteristics who underwent into either of these interventions, it was very clear that patients in DC cohort have more serious and low pre-op characteristics than the CO group. Nonetheless, brain herniation and advanced age act as independent factor for predicting the outcome irrespective of the intervention.
