We aimed to estimate the SWE for rotator cuff repair (with decompression and debridement) compared to either decompression and debridement alone or to non-surgical treatment for people with atraumatic shoulder pain.\u0000Methods: Benefit-harm trade-off study. We recruited English speaking adults aged 45-75 years with shoulder pain of intensity ≥4 (on a 0-10 scale) for ≥6 months to our online survey through paid advertising on Facebook. Participants must have sought care in the past 6-months and could not have had recent shoulder surgery or significant recent shoulder trauma. Participants were explained three treatments: rotator cuff repair (with subacromial decompression and debridement), subacromial decompression and debridement alone and non-surgical treatment. Participants completed the benefit-harm trade-off survey to determine the SWE of improvements in pain and function for rotator cuff repair compared to the other treatments and again after one week to assess reliability. We used univariable linear regression to estimate associations between baseline characteristics and SWE.\u0000Results: We recruited 56 participants. The mean (standard deviation) age was 58.4 (6.7) years and 39 (70%) were female. For rotator cuff repair to be worthwhile compared to decompression and debridement alone participants needed to see at least a median 40% (interquartile range (IQR) 20-62.5) between-group improvement in pain and function. Compared to non-surgical treatment, the SWE was a median 40% (IQR 30-60). On the Western Ontario Rotator Cuff (WORC) Index the SWE values equate to a between-group improvement of 28/100 points (533/2100 on the raw WORC score). Female sex was associated with larger SWEs for both comparisons. Reliability analyses were underpowered, 25/56(45%) provided follow-up data; the intraclass correlation coefficient estimates ranged from 0.60-0.77. Conclusions: This SWE indicates the benefit required by people with shoulder pain to consider the costs and risks of surgical rotator cuff repair worthwhile is larger than previously estimated minimum clinically important differences (13.5-28/100 on the WORC Index). This SWE may be used to inform the design or interpret the findings of trials of these comparisons.","PeriodicalId":501051,"journal":{"name":"medRxiv - Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141774072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Angiotensin-converting enzyme (ACE) inhibitors have shown promise in animal studies and limited clinical trials for reducing scar formation. However, the causal relationship between ACE inhibition and skin fibrosis remains unclear.\u0000Methods: This study employed two-sample Mendelian randomization (MR) analysis to investigate the causal effect of ACE inhibition on skin fibrotic diseases. We utilized genetic variants associated with serum ACE levels, ACE inhibition, and effect of decreasing blood pressure by ACE inhibition as instrumental variables. We analyzed the association between these exposures and the incidence of skin fibrosis, hypertrophic scars, and keloids using various MR methods.\u0000Results: We found no significant causal relationship between genetically proxied serum ACE levels, or local skin tissue ACE expression and the risk of skin fibrosis, hypertrophic scars, or keloids. Additionally, there was no direct causal relationship between the effect of ACE inhibitors on blood pressure reduction and the risk of skin fibrotic diseases. However, we observed a significant negative association between systolic blood pressure (SBP) and the risk of hypertrophic scars. Conversely, we found a positive association between β-blockers and the risk of skin fibrosis.\u0000Conclusion: Our findings suggest that ACE inhibitors do not have a direct causal effect on the risk of skin fibrotic diseases, including hypertrophic scars and keloids. This challenges the potential of ACE inhibitors as a therapeutic option for preventing or treating these conditions.","PeriodicalId":501051,"journal":{"name":"medRxiv - Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141774105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its diagnosis, however, has many pitfalls including lack of a pathognomonic sign or symptoms, and the low predictive value of laboratory testing. Appendicitis is a leading cause of malpractice concerns. Methods: Using Google Case Law, we used the search terms appendicitis, and malpractice to identify appendicitis litigation cases. We included cases published since 2020. We included any case where a confirmed diagnosis of appendicitis was made. We included cases filed for malpractice due to complications of appendicitis and its treatment. Outcomes of interest included: the state the case was published, the defendants, the date of when the patient first complained of abdominal pain to when they had had an appendectomy/treatment, diagnostics and consultations, medical and legal issues, and final verdict/opinion/decisions on the cases.\u0000Results: A total of 44 cases were identified, which were screened for inclusion. A total of 14 cases met the inclusion criteria and were analyzed. Most cases did not present in an atypical way, the majority of patients presented with clear statements of abdominal pain of varying severity. The majority of the defendants were MDs and hospitals. The average time from symptom to diagnosis was 2.4 +/- 2.1 days, while the longest time for diagnosis was 7 days. The leading medico-legal issues were failure to diagnose and delayed diagnosis, while among the cases, 35.7% had outcomes in favor of the plaintiff.

Metastatic CRC (mCRC) presents a significant challenge with a grim 5-year survival rate of 14%. Emerging evidence suggests that tumors with DNA mismatch repair deficiency (dMMR) and high microsatellite instability (MSI-H) respond well to immune checkpoint inhibitors (ICIs), marking a paradigm shift in therapeutic approaches. This systematic review and meta-analysis aim to comprehensively assess Pembrolizumab, Nivolumab, and the combination of Nivolumab and Ipilimumab in advanced CRC, considering their significant antitumor efficacy in MSI-H/dMMR mCRC. Methods Following PRISMA guidelines and Cochrane Handbook standards, this study covers 2014 to 2024, involving advanced CRC patients treated with ICIs. A comprehensive literature search employed 12 independent authors across eight databases. Parameters such as overall survival, progression-free survival, and objective response rate were extracted. The Cochrane Collaboration's Risk of Bias version 2 tool assessed risk. Statistical analysis utilized mean difference and risk ratios with random-effect models due to anticipated heterogeneity. Robustness was ensured through publication bias analysis and sensitivity meta-analysis. Linear regression explored associations in subgroup analysis. Results The meta-analysis evaluated ORR and OS across different immunotherapy interventions. Nivolumab, Nivolumab+Ipilimumab, and Pembrolizumab exhibited varying ORR and OS effect sizes with corresponding heterogeneity levels. Progression-free survival (PFS) analysis also showed diverse effect sizes and heterogeneity levels across the three interventions. The study provides a comprehensive overview of response rates and survival outcomes for these immunotherapies in advanced CRC. Conclusions The study concludes that combination immunotherapy, particularly Nivolumab and Ipilimumab, presents a promising avenue for advanced CRC treatment, showing superior efficacy. Pembrolizumab monotherapy also exhibited promise. While the study offers valuable insights, the identified heterogeneity emphasizes the need for additional research. Adverse effects were generally low, supporting the viability of the studied immunotherapies. The study acknowledges limitations and calls for ongoing investigation to refine and validate these findings, marking a pioneering effort in systematically comparing short-term and long-term effects of anti-CTLA-4 and anti-PD-1 therapies in CRC.","PeriodicalId":501051,"journal":{"name":"medRxiv - Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141549775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We described the prevalence of each reported complication. Of patients with TIP, we pooled CFR using random-effects meta-analysis and stratified by United Nations region, sex, and number of perforations per patient. Results: We included 46 articles reporting on 4,317 patients with TIP. The most prevalent post-operative complications were wound or surgical site infection in 1,537 (50.7%) of 3,030 patients, wound dehiscence in 308 (16.1%) of 1,909, and chest infection in 136 (15.6%) of 872. Overall, the pooled CFR (95%CI) of patients with TIP was 15.6% (12.5-18.9%), and was 20.5% (17.1-23.9%) in 30 observations from the African region, 5.7% (2.6-9.6%) in 15 observations from the Asian region, and 12.2% (0.90-30.4%) in three observations from the Americas.

Very elderly patients (age > 80) might have significantly higher incidence of worse management morbidity and mortality after primary ICH. The aim of this study was to explore presenting status and pre-existing comorbidities in octogenarians and compare the inpatient management outcomes with younger counterparts. Methods The Stony Brook ICH database is a retrospective cohort of 814 patients that presented with primary ICH from January 2011 to January 2021. Demographic data, presenting symptoms, pre-existing medical conditions, and imaging findings were recorded. Inpatient outcomes and functional state presented as modified Rankin Scale (MRS) at discharge were evaluated. Results Our results indicate octogenarians had significantly higher baseline MRS and comorbidities such as hypertension, hyperlipidemia, and atrial fibrillation at presentation. Similarly, usage of statins, antiplatelets, and anticoagulants were significantly higher in this age group. Octogenarians were also found to have higher average volume of hematoma at presentation. Our results indicate significantly higher discharge MRS, and inpatient mortality in the very elderly group. Conclusion Present study demonstrates a wide variety of pre-existing factors that correlate with worse outcomes amongst octogenarians presenting with primary ICH. Given the importance of aging population as a major healthcare issue in many parts of world, it is crucial to continue exploring these associations in future research.

This study aimed to identify the maximum hematoma volume suitable for conservative treatment and the volume that represents an absolute indication for surgery in patients with basal ganglia hemorrhage. Methods: A retrospective analysis was performed on the medical records of patients admitted for basal ganglia hemorrhage from 2019 to 2021. The data encompassed personal history, general information and diagnostic imaging records, particularly CT brain scans from the initial ER visit, were examined to ascertain hematoma volume. The comparison focused on evaluating the outcomes of patients who received medical treatment compared to those who underwent surgical intervention, mainly considering various hematoma volumes, and was conducted using multivariate logistic analysis. Results: In a study of 387 cases of basal ganglia hemorrhage, analysis of medical treatment alone across various hematoma volumes revealed that the group with volumes between 10 and 39.9 ml showed no significant difference in mortality compared to the group with volumes less than 10 ml. The Receiver Operating Characteristics (ROC) curve identified a 45.3 ml cutoff for survival prediction with medical treatment alone. Notably, patients in the subgroup undergoing surgical intervention with a hematoma volume less than 30 ml exhibited significantly higher mortality than those who did not undergo surgery. Conversely, there was a pronounced and statistically significant trend toward increased survival in the group with a hematoma volume of at least 60 ml. Conclusions: The application of medical treatment alone is suitable for hematoma volumes ranging from 0 to 45.3 ml, whereas volumes of 60 ml or more serve as a clear indication for surgical intervention in patients with basal ganglia hemorrhage.","PeriodicalId":501051,"journal":{"name":"medRxiv - Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of body position on ICP is well studied, with ICP greater when supine than when upright. In daily life the head is frequently moved away from the neutral position but how this impacts ICP dynamics is unclear. Knowledge of ICP dynamics in different head-on-body positions may improve future treatments that restore normal ICP dynamics such as cerebrospinal fluid (CSF) drainage shunts.\u0000We recruited 57 relatively well, ambulatory patients undergoing clinical ICP monitoring for investigation of possible CSF dynamics disturbances. Forty-one patients were non-shunted, seven had a working shunt and nine had a malfunctioning shunt. We measured ICP and ICP pulsatility (pulse amplitude) over 10 or 20s in different combinations of head and body positions. Positions included right and left head turn and forward tilt in upright (seated, standing) and supine body positions, and right and left lateral tilt and backward tilt in upright body positions.\u0000ICP increased by 3-9 mmHg, on average, when the head moved away from neutral to each head position in upright and supine body positions, except for head forward tilt when supine, where ICP did not change. The increase in ICP with head turn and forward tilt in upright body positions was larger in patients with a malfunctioning shunt than with no shunt or a functioning shunt. Pulsatility also increased by 0.5-2 mmHg on average when the head moved away from neutral to each head position in upright and supine body positions, except for head forward tilt in upright body positions where pulsatility slightly decreased by 0.7 mmHg on average.\u0000ICP and pulsatility generally increase when the head is moved away from the neutral position, but this depends on a combination of head and body position and shunt status. We propose our results can be explained by a combination of changes to neck vasculature and head orientation relative to gravity. Our findings provide potential reason for patient reports that ICP-related symptoms can be induced and/or exacerbated by head movement and could explain behaviours that avoid excess head movement, such as turning the body rather than the head when looking to the side.","PeriodicalId":501051,"journal":{"name":"medRxiv - Surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
