Outcomes of arthroscopic coracoclavicular management for acromioclavicular joint injuries: A systematic review.

Introduction: Various surgical procedures for coracoclavicular (CC) ligament repair have been described for symptomatic acromioclavicular joint dislocations, with none emerging as a clear gold standard. There has been increased interest in arthroscopic approaches. This systematic review evaluates clinical outcomes after arthroscopic surgeries used to treat chronic and acute AC joint dislocations. Methods: We searched three databases (PubMed, EMBASE, and OVID [MEDLINE]) from database inception to December 20, 2022. Studies were included if they met the following criteria: studies evaluating humans, English language studies, level of evidence I to IV, and studies investigating clinical outcomes in patients following arthroscopic surgery for coracoclavicular ligament reconstruction. Studies on open reconstruction techniques only were excluded. Primary outcomes included function/pain scores, coracoclavicular distances, complications, and revision rates. Results: Fifty-two studies were included. In 33 studies, postoperative Constant-Murley scores ranged from 82.8 to 99 points. Postoperative VAS scores ranged from 0.3 to 4.1 in 16 studies. In 46 studies, revision rates ranged from 0 % to 44.4 %. We did not observe a difference in revision rates between chronic and acute cases (P = 0.268). Complications were more common in chronic than acute cases (25.5 % vs. 16.4 %; P < 0.001). Conclusions: Arthroscopic surgery for chronic and acute CC ligament injuries exceeds the MCID and PASS for several outcomes, with low failure rates. Arthroscopic CC reconstruction is a safe and effective alternative for chronic AC joint dislocations. Level of evidence: IV (Systematic Review of Level I-IV Studies).

Evaluating the Efficacy of Immune Checkpoint Inhibitors in Elderly Patients: A Systematic Review and Meta-analysis.

In this chapter, we outline the steps for designing and conducting a rigorous systematic review and meta-analysis, focusing on the efficacy of immune checkpoint inhibitors (ICIs) in elderly patients. ICIs have improved survival rates in advanced cancers, yet their effectiveness in older populations remains unclear. We detail the essential processes involved in both systematic reviews and meta-analyses. We can evaluate the efficacy of ICIs in elderly patients with advanced cancer, examining outcomes such as overall survival and progression-free survival.

Establishment and validation of a risk prediction model for sarcopenia in gastrointestinal cancer patients: A systematic review and meta-analysis-based approach.

OBJECTIVE: The study aimed to develop a model to predict the risk of sarcopenia in gastrointestinal cancer patients. The goal was to identify these patients early and classify them into different risk categories based on their likelihood of developing sarcopenia. METHODS: This study evaluated risk factors for sarcopenia in patients with gastrointestinal cancers through a systematic review and meta-analysis. The natural logarithm of the combined risk estimate for each factor was used as a coefficient to assign scores within the model for risk prediction. Data from 270 patients with gastrointestinal cancers, collected between October 2023 and April 2024, was used to assess the predictive performance of the scoring model. RESULTS: The analysis included 17 studies that included 9405 patients with gastrointestinal cancers, out of which 4361 had sarcopenia. The model identified several significant predictors of sarcopenia, including age (OR = 2.45), sex (OR = 1.15), combined diabetes (OR = 2.02), neutrophil-to-lymphocyte ratio (NLR) category (OR = 1.61), TNM stage (OR = 1.61), and weight change (OR = 1.60). Model validation was performed using an external cohort through logistic regression, resulting in an area under the curve (AUC) of 0.773. This model attained a sensitivity of 0.714 and a specificity of 0.688 and ultimately selected 16.5 as the ideal critical risk score. Furthermore, an AUC of 0.770 was obtained from Bayesian model validation; the optimal critical risk score was determined to be 19.0, which corresponds to a sensitivity of 0.658 and a specificity of 0.847. CONCLUSIONS: The model of risk prediction developed through systematic review and meta-analysis demonstrates substantial for sarcopenia in patients with gastrointestinal cancers. Its clinical usability facilitates the screening of patients at high risk for sarcopenia.

The effect of active vitamin D supplementation on body weight and composition: A meta-analysis of individual participant data.

BACKGROUND & AIMS: Obesity is associated with vitamin D (VitD) deficiency. However, previous studies showed mixed effects of VitD (25-hydroxyVitD/calcidiol) supplementation on body weight. The biological actions of VitD require the hydroxylation of inactive VitD into active VitD (1.25-dihydroxyVitD/calcitriol). This step is highly regulated; therefore, supplementing with inactive VitD might not be sufficient to overcome the potential adverse health effects of VitD deficiency. The objective of this study was to conduct a systematic review and individual participant data (IPD) meta-analysis of data acquired from randomised placebo-controlled calcitriol trials (RCTs) to determine the effects of calcitriol on body weight and weight-related parameters. METHODS: Studies were identified from MEDLINE, EMBASE, and CENTRAL databases up to January 27, 2024, and excluded those involving dialysis or cancer patients. We obtained IPD from eligible trials and assessed bias using the Cochrane Collaboration risk-of-bias tool and methodological quality using the Heyland Methodological Quality Score. The study was prospectively registered with PROSPERO (CRD42017076202). RESULTS: Although none of the studies reported information regarding our primary objective, we obtained IPD for 411 patients, with 206 randomised to receive calcitriol and 205 to placebo. This dataset enabled us to conduct an IPD meta-analysis with 17,084 person-months of follow-up (median: 11 months). Meta-analysis showed that calcitriol does not alter body weight, BMI, waist circumference, fat mass or lean body mass compared to placebo. Adjusting for age and sex did not alter the outcomes. CONCLUSIONS: In conclusion, this systematic review and IPD meta-analysis indicate that calcitriol does not affect body weight in normal-weight postmenopausal women and lean patients with type 1 diabetes nor in people suffering from obesity, type 2 diabetes and chronic kidney disease. Whether calcitriol lowers body weight in VitD-sufficient people with obesity remains to be elucidated.

Blood-dominant disease in late-and-early-onset lupus: A systematic review and meta-analysis.

OBJECTIVES: Numerous studies have explored hematological manifestations in early-onset systemic lupus erythematosus (erSLE) (age ≤ 50) and late-onset SLE (ltSLE) patients (age > 50), yielding diverse results. This study employs a meta-analysis to examine differences in hematologic manifestations between ltSLE and erSLE. METHODS: Studies investigating the frequency of hematological manifestations in ltSLE patients were included. The frequencies of autoimmune hemolytic anemia (AIHA), thrombocytopenia (TP), lymphopenia, leukopenia, lymphadenopathy, and thrombosis were compared between erSLE and ltSLE groups. Two authors independently reviewed and assessed data consistency among abstracts, tables, and text to mitigate bias. Forest plots were utilized to compare odds ratios (95 % CI) of hematological manifestations by age groups, and study heterogeneity was evaluated using I2. RESULTS: The analysis included 39 eligible studies with 19,103 SLE patients (16,314 erSLE, 2789 ltSLE). Among these studies, 28 reported AIHA which was found to be more frequent in erSLE (OR = 1.29, 95 %CI = 1.11-1.39, p = 0.0008). Twenty studies provided data on lymphopenia which was found to be more frequent in erSLE (OR = 1.184, 95 %CI = 1.063-1.318, p = 0.0021). 32 studies included data on leukopenia and the frequency was higher in erSLE (OR: 1.338, 95 %CI: 1.22-1.47, p < 0.0001). Lymphadenopathy was more prevalent in erSLE (OR = 2.32, 95 % CI = 1.61-3.34, p < 0.0001). No significant difference was observed in thrombosis and TP frequency between the two groups. CONCLUSION: Attributing hematological findings to SLE in late-onset patients presents challenges due to comorbidities and polypharmacy. Overall, the frequencies of AIHA, lymphopenia, leukopenia, and lymphadenopathy were more common in erSLE patients compared to ltSLE in this study.

Association between depression and anxiety with the risk and flare of inflammatory bowel disease: a systematic review and meta-analysis.

Inflammatory bowel disease (IBD) is a chronic condition characterized by inflammation in the gastrointestinal tract. Previous studies have suggested a potential association between mental disorders, such as depression and anxiety, and the risk and flare of IBD. However, the findings have been inconsistent. This study aimed to conduct a systematic review and meta-analysis to assess the relationship between mental disorders and IBD. A comprehensive literature search was performed to identify relevant studies. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to determine the association between mental disorders and the risk and flare of IBD. Heterogeneity between studies was assessed using the I2 statistic. Sensitivity analysis was conducted to evaluate the stability of the results. A total of seven studies met the inclusion criteria and were included in the meta-analysis. The pooled results demonstrated a significant association between symptoms of depression at baseline and an increased risk of disease activity flare during longitudinal follow-up, with an OR of 1.69 (95% CI 1.34, 2.13). However, there was high heterogeneity between studies (I2 = 82%). Furthermore, patients who underwent surgery had a higher risk of disease activity flare (OR: 1.49, 95% CI 1.13, 1.95), and hospitalization was also identified as a contributing factor (OR: 1.22, 95% CI 1.10, 1.36). This meta-analysis provides evidence for a significant association between symptoms of depression and the risk of disease activity flare in IBD. However, the high heterogeneity observed between studies suggests the need for further research to explore potential moderators and underlying mechanisms. These findings highlight the importance of addressing mental health in the management and treatment of patients with IBD.

The Utility and Safety of Prophylactic Tranexamic Acid in Tonsillectomy: A Systematic Review and Meta-analysis.

OBJECTIVE: We conducted a systematic review of randomized controlled trials (RCTs) to evaluate the efficacy of tranexamic acid (TXA) in reducing posttonsillectomy hemorrhage (PTH). DATA SOURCES: We searched MEDLINE, EMBASE, and CENTRAL for RCT comparing prophylactic TXA to control in patients undergoing tonsillectomy. REVIEW METHODS: Per Preferred Reporting Items for Systematic Review and Meta-analysis guidelines, the databases were searched from date of inception through October 2023. RCTs of patients undergoing tonsillectomy or adenotonsillectomy and receiving prophylactic TXA versus control were included. Two reviewers screened citations, extracted data, assessed the risk of bias, and classification of Grading of Recommendations, Assessment, Development, and Evaluation independently. Standardized mean difference with 95% confidence interval (CI) was applied for continuous variables. Dichotomous data were expressed as relative risk with 95% CI. RESULTS: A total of 10 RCT were included in our quantitative analysis. Eight studies reported on PTH rate. Prophylactic TXA showed non-significant decrease in PTH (relative risk or risk ratio [RR]: 0.62 [0.35, 1.10]). Sensitivity analysis showed significant decrease in PTH after exclusion of High-risk bias studies (RR: 0.48 [0.30, 0.77]). Intraoperative blood loss volume was significantly lower in the TXA group (35.59 mL [-48.19, -22.99]). CONCLUSION: Overall, this study showed a tendency toward lesser PTH rate with prophylactic TXA. However, this tendency only reaches statistical significance when studies with high risk of bias are excluded. Well-designed trials are still needed to support our observations.

The immediate, intermediate, and long-term effectiveness of audiovisuals for providing pre-treatment information to patients with cancer: A systematic review.

OBJECTIVE: To assess the effectiveness of audiovisuals in providing pre-treatment information to patients with cancer. Following the Six Function Model of Medical Communication, we distinguish between immediate, intermediate, and long-term outcomes. METHODS: A systematic search was performed in five electronic databases for quantitative studies comparing the addition of audiovisuals with standard care or alternative interventions. Quality was assessed using Cochrane's Risk of Bias 2. RESULTS: After abstract (n = 10,179) and full-text (n = 85) screening, 37 articles were included. Audiovisuals positively impacted patients' anxiety, knowledge, understanding, and physiological responses shortly after the consultation, particularly when video was compared with standard verbal care without audiovisual. Only five studies measured long-term outcomes, leaving the long-term effectiveness of audiovisuals unexplored. Majority of studies showed 'high risk of bias' (n = 34). CONCLUSION: Although caution is warranted because of the variability in study design and quality, the results suggest potential benefits of using audiovisuals alongside interpersonal communication. PRACTICAL IMPLICATIONS: More high-quality and longitudinal research is needed with emphasis on comparing counseling with and without usage of audiovisual tools. Healthcare providers can improve the short-term impact of information provision by using audiovisuals alongside standard care, but should carefully consider content, for whom, how, and timing.

Quality of life issues in patients with ductal carcinoma in situ: a systematic review.

PURPOSE: Ductal carcinoma in situ (DCIS) of the breast is one of the most common pre-invasive cancers diagnosed in women. Quality of life (QoL) is extremely important to assess in studies including these patients due to the favorable prognosis of the disease. The primary objective of this systematic review was to compile a comprehensive list of QoL issues, all existing QoL assessment tools, and patient-reported outcome measures used to assess DCIS. METHODS: A search was conducted on Ovid MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials databases from inception to August 2023, using keywords such as "ductal carcinoma in-situ", "quality of life", and "patient-reported outcomes." QoL issues and QoL tools in primary research studies were extracted. RESULTS: A total of 67 articles identified issues pertaining to patients with DCIS spanning physical, functional, and psychosocial QoL domains. Physical and functional issues observed in patients included pain, fatigue, and impaired sexual functioning. Psychosocial issues such as anxiety, depression, and confusion about one's disease were also common. QoL tools included those that assessed general QoL, breast cancer-specific tools, and issue-specific questionnaires. CONCLUSION: The current instruments available to assess QoL in patients with DCIS do not comprehensively capture the issues that are pertinent to patients. Thus, the modification of existing tools or the creation of a DCIS-specific QoL tool is recommended to ensure that future research will be sensitive towards challenges faced by patients with DCIS.

Effects of dyadic interventions on psychological outcomes among cancer patients with non-active treatment: a systematic review and meta-analysis.

OBJECTIVE: Cancer and its treatment can generate substantial psychological distress (depression and anxiety). The objective of this systematic review and meta-analysis is to explore the effectiveness of dyadic interventions on psychological outcomes in cancer patients with non-active treatment and to test subgroup analyses to explore the source of heterogeneity affecting effect sizes. DESIGN: Systematic searching across eight databases identified studies related to dyadic interventions for psychological outcomes of cancer patients published between 2007 and 2022. Rigorous inclusion and exclusion criteria were utilized. Random-effects models were used to compute effect sizes with Hedge's g, forest plot, and Q and I2 statistics to measure heterogeneity. Moderator analyses were examined. RESULTS: Eleven primary studies were identified (938 patients with cancer, 56.14 ± 7.29 years old). Overall, dyadic interventions significantly improved depression (g = .36, 95% confidence interval .026 to .68, I2 = 76%) and anxiety (g = .29, 95% confidence interval 0.14 to .45, I2 = 0%) compared to controls. With subgroup analyses, fidelity of dyadic interventions, number of weeks across intervention, and number of days after intervention measured were moderators affecting effect sizes. CONCLUSION: Dyadic interventions appear to be effective among adults with cancer with non-active treatment. Additional research is needed to explore the efficacy of dyadic interventions among more diverse samples and to examine routes for integrating dyadic interventions into practice. IMPLICATIONS FOR CANCER SURVIVORS: Adult with cancer might participate in the dyadic intervention for improving psychological outcomes.

Predicting the resolution of hypertension following adrenalectomy in primary aldosteronism: Controversies and unresolved issues a narrative review.

BACKGROUND: Hypertension resolution following adrenalectomy in patients with primary aldosteronism (PA) remains a critical clinical challenge. Identifying preoperatively which patients will become normotensive is both a priority and a point of contention. In this narrative review, we explore the controversies and unresolved issues surrounding the prediction of hypertension resolution after adrenalectomy in PA. METHODS: A comprehensive literature review was conducted, focusing on studies published between 1954 and 2024 that evaluated all studies that discussed predictive models for hypertension resolution post-adrenalectomy in PA patients. Databases searched included MEDLINE®, Ovid Embase, and Web of Science databases. RESULTS: The review identified several predictors and predictive models of hypertension resolution, including female sex, duration of hypertension, antihypertensive medication, and BMI. However, inconsistencies in study designs and patient populations led to varied conclusions. CONCLUSIONS: Although certain predictors and predictive models of hypertension resolution post-adrenalectomy in PA patients are supported by evidence, significant controversies and unresolved issues remain. While the current predictive models provide valuable insights, there is a clear need for further research in this area. Future studies should focus on validating and refining these models.

Nebulized tranexamic acid for treatment of post-tonsillectomy bleeding: a systematic review and meta-analysis.

PURPOSE: Post-tonsillectomy bleeding (PTB) is a significant complication and common reason for emergency department (ED) visits. Limited literature has investigated the clinical efficacy of nebulized tranexamic acid (TXA) for treating PTB; however, the results were conflicting and not comprehensively summarized. This study aimed to provide the first-ever systematic review encompassing all literature exploring the efficacy and safety of nebulized TXA in treating PTB. METHODS: We screened six databases until 01-July-2024, for relevant studies and assessed their quality using validated tools. We provided a qualitative summary of baseline characteristics and clinical data. The primary endpoint was the reoperation rate to manage PTB, and its effect size was aggregated as a proportion or risk ratio (RR) with a 95% confidence interval (CI) using a random-effects model. RESULTS: We analyzed nine studies (2 case reports, 4 case series, and 3 retrospective comparative studies), all of which demonstrated good quality and low risk-of-bias. In studies using nebulized TXA for treating PTB (n = 9 studies), the pooled proportion of reoperation to control bleeding was 0.27 (95% CI: 0.08-0.5). The rate of reoperation to control bleeding was significantly lower in the nebulized TXA arm compared to the no-TXA arm (n = 3 studies, RR = 0.55, 95% CI [0.39-0.77], p < 0.001). CONCLUSION: Nebulized TXA is safe and promising for treating PTB. This is evidenced by its high efficacy in achieving hemostasis in acute settings during ED visits and reducing the rate of reoperations needed to control PTB. Further high-quality investigations are warranted to corroborate these findings.

Complications and failure after Kock continent ileostomy: A systematic review and meta-analysis.

BACKGROUND: A significant number of patients experience complications of the Kock pouch (KP) warranting revision or excision. This systematic review aimed to assess the pooled prevalence and risk factors for complications and failure of the KP. METHODS: This Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA)-compliant systematic review (CRD42023416961) searched PubMed, Scopus, and Web of Science for studies on adult patients with Kock continent ileostomy published after the year 2000. The main outcome measures were revision, complications, and failure of the KP. Risk factors for complications and failure were assessed using a meta-regression analysis. Risk of bias was assessed using the ROBINS-1 tool. A proportional meta-analysis of the main outcomes was performed. RESULTS: A total of 19 studies (2042 patients) were included. The weighted mean prevalence of complications was 60.4% [95% confidence interval (CI): 46.1-74.7%], of pouch revision was 46.6% (95% CI: 38.5-54.7%), and of pouch failure was 12.9% (95% CI: 9.3-16.4%). Studies conducted in the USA had a mean failure prevalence of 12.6% (95% CI: 6.2-18.9%) comparable to studies conducted in Europe (11.1%; 95% CI: 7.5-14.7%). Factors associated with higher complications were increased body mass index (BMI) and previous ileoanal pouch anastomosis (IPAA); however, these factors were not associated with increased pouch failure. CONCLUSIONS: The KP is a highly complex operation as shown by a pooled complication prevalence of 60%, and thus, it should be only performed by experienced surgeons. Despite the high prevalence of complications and need for revisional surgery, patients are keen to preserve their KP. Increased BMI and a previous failed IPAA are risk factors for pouch complications, but not failure.

Systematic review of prognostic factors for poor outcome in people living with dementia that can be determined from primary care medical records.

BACKGROUND: Dementia has a major impact on individuals, their families and caregivers, and wider society. Some individuals experience a faster decline of their function and health compared to others. The objective of this systematic review was to determine prognostic factors, measurable in primary care, for poor outcome in people living with dementia. METHODS: Cohort studies set in the community or primary care, and examining prognostic factors for care home admission, cognitive decline, or palliative care were included. Databases were searched from inception to 17th June 2022. Identified papers were screened, the risk of bias assessed using Quality in Prognostic Studies (QUIPS) tool, and data extracted by 2 reviewers, with disagreements resolved by consensus or a 3rd reviewer. A narrative synthesis was undertaken, informed by GRADE, taking into consideration strength of association, risk of bias and precision of evidence. Patient and Public Involvement and Engagement (PPIE) and stakeholder input was obtained to prioritise factors for further investigation. RESULTS: Searches identified 24,283 potentially relevant titles. After screening, 46 papers were included, 21 examined care home admission investigating 94 factors, 26 investigated cognitive decline as an outcome examining 60 factors, and 1 researched palliative care assessing 13 factors. 11 prognostic factors (older age, less deprived, living alone, white race, urban residence, worse baseline cognition, taking dementia medication, depression, psychosis, wandering, and caregiver's desire for admission) were associated with an increased risk of care home admission and 4 prognostic factors (longer duration of dementia, agitation/aggression, psychosis, and hypercholesterolaemia) were associated with an increased risk of cognitive decline. PPIE and other stakeholders recommended further investigation of 22 additional potential prognostic factors. CONCLUSIONS: Identifying evidence for prognostic factors in dementia is challenging. Whilst several factors highlighted as of relevance by our stakeholder groups need further investigation, inequalities may exist in care home admission and there is evidence that several prognostic factors measurable in primary care could alert clinicians to risk of a faster progression.

Global patterns of lake microplastic pollution: Insights from regional human development levels.

Microplastics have emerged as a pervasive pollutant across various environmental media. Nevertheless, our understanding of their occurrence, sources, and drivers in global lakes still needs to be completed due to limited data. This study compiled data from 117 studies (2016-May 2024) on microplastic contamination in lake surface water and sediment, encompassing surface water samples in 351 lakes and lake sediment samples in 200 lakes across 43 countries. Using meta-analysis and statistical methods, the study reveals significant regional variability in microplastic pollution, with concentrations ranging from 0.09 to 207,500 items/m3 in surface water and from 5.41 to 18,100 items/kg in sediment. Most microplastics were under 1 mm in particle size, accounting for approximately 79 % of lake surface water and 76 % of sediment. Transparent and blue microplastics were the most common, constituting 34 % and 21 % of lake surface water and 28 % and 18 % of sediment, respectively. Fibers were the dominant shape, representing 47 % of lake surface water and 48 % of sediment. The primary identified polymer types were polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET). Countries like India, Pakistan, and China had higher contamination levels. Positive correlations were found between microplastic abundance in surface water and factors like human footprint index (r = 0.29, p < 0.01), precipitation (r = 0.21, p < 0.05), and net surface solar radiation (r = 0.43, p < 0.001). In contrast, negative correlations were observed with the human development index (r = -0.61, p < 0.01) and wind speed (r = -0.42, p < 0.001). In sediment, microplastics abundance correlated positively with the human footprint index (r = 0.45, p < 0.001). This study underscores the variability in microplastic pollution in global lakes and the role of human activities and environmental factors, offering a valuable reference for future research.

Intraoperative Management of Iatrogenic Durotomy in Endoscopic Spine Surgery: A Systematic Review.

This review aims to systematically evaluate the incidence, management strategies, and clinical outcomes of iatrogenic durotomy (ID) in endoscopic spine surgery and to propose a management flowchart based on the tear size and associated complications. A comprehensive literature search was conducted, focusing on studies involving endoscopic spinal procedures and incidental durotomy. The selected studies were analyzed for management techniques and outcomes, particularly in relation to the size of the dural tear and the presence of nerve root herniation. Based on these findings, a flowchart for intraoperative management was developed. A total of 14 studies were included, encompassing 68,546 patients. Varying incidences of ID, with management strategies largely dependent on the size of the dural tear, were found. Small tears (less than 5 mm) were often left untreated or managed with absorbable hemostatic agents, while medium (5-10 mm) and large tears (greater than 10 mm) required more complex approaches like endoscopic patch repair or open surgery. The presence of nerve root herniation necessitated immediate action, often influencing the decision to convert to open repair. Effective management of ID in endoscopic spine surgery requires a nuanced approach tailored to the size of the tear and specific intraoperative challenges, such as nerve root herniation. The proposed flowchart offers a structured approach to these complexities, potentially enhancing clinical outcomes and reducing complication rates. Future research with more rigorous methodologies is necessary to refine these management strategies further and broaden the applications of endoscopic spine surgery.

Complications in Minimally Invasive Spine Surgery in the Last 10 Years: A Narrative Review.

OBJECTIVE: Minimally invasive spine surgery (MISS) employs small incisions and advanced techniques to minimize tissue damage while achieving similar outcomes to open surgery. MISS offers benefits such as reduced blood loss, shorter hospital stays, and lower costs. This review analyzes complications associated with MISS over the last 10 years, highlighting common issues and the impact of technological advancements. METHODS: A systematic review following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines was conducted using PubMed, MEDLINE, Embase via OVID, and Cochrane databases, covering publications from January 2013 to March 2024. Keywords related to MISS and complications were used. Studies on adult patients undergoing MISS with tubular, uniportal, or biportal endoscopy, reporting intraoperative or postoperative complications, were included. Non-English publications, abstracts, and small case series were excluded. Data on MISS approach, patient demographics, and complications were extracted and reviewed by 2 independent researchers. RESULTS: The search identified 880 studies, with 137 included after screening and exclusions. Key complications in cervical MISS were hematomas, transient nerve root palsy, and dural tears. In thoracic MISS, complications included cerebrospinal fluid leaks and durotomy. In lumbar MISS, common complications were incidental dural injuries, postoperative neuropathic conditions, and disc herniation recurrences. Complications varied by surgical approach. CONCLUSION: MISS offers reduced anatomical disruption compared to open surgery, potentially decreasing nerve injury risk. However, complications such as nerve injuries, durotomies, and hardware misplacement still occur. Intraoperative neuromonitoring and advanced technologies like navigation can help mitigate these risks. Despite variability in complication rates, MISS remains a safe, effective alternative with ongoing advancements enhancing its outcomes.

Efficacy of Ruxolitinib with corticosteroids in idiopathic pneumonia syndrome post-allogeneic hematopoietic stem cell transplantation: A single-center experience and systematic review.

BACKGROUND: Idiopathic Pneumonia Syndrome (IPS) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a life-threatening complication with high morbidity and mortality. IPS is thought to arise from damage caused by various inflammatory mediators. This study assesses the effectiveness of Ruxolitinib, a Janus Kinase (JAK) 1 and 2 inhibitor that blocks cytokine production, in combination with corticosteroids (CS) for managing IPS after allo-HSCT, compared to the conventional use of CS alone in a case series and a systematic review of previously published literature. METHODS: The study includes a retrospective case series of three patients treated for IPS with Ruxolitinib and CS from the University of Kansas Medical Center and a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement 2020 guidelines. The systematic review encompassed seven studies involving 346 cases including three cases from the case series. Statistical analyses were conducted using SPSS v.25. RESULTS: The case series included three patients with IPS after allo-HSCT who received ruxolitinib and CS with favorable results. All patients showed substantial improvement with no IPS-associated mortality. Two of the three patients in the case series were discharged on a 2 L nasal cannula, which was later discontinued during follow-up visits, while the third was discharged on room air. There was marked improvement observed on the computed tomography (CT) following the use of ruxolitinib. Of the total 346 cases included in the systematic review, the median age was 46.6 years (Range 5-72), and 62 % were males. The primary disorders were acute leukemia (52 %), chronic myeloid leukemia (12 %), myelodysplastic syndrome (11 %), Lymphoma (10 %), and others (21 %). Stem cell sources were peripheral blood (45 %), bone marrow (49 %), and cord blood (6 %). Donor types involved match unrelated (55 %), match related (36 %), and mismatched related (4.5 %). Most patients received myeloablative conditioning (81 %). Acute GVHD was observed in 47 %, and chronic GVHD in 38 %. The primary treatment was CS (96 %), with limited use of ruxolitinib (1 %) and etanercept (9.5 %). The mortality rate was 63.3 %, whereas in our case series with the use of ruxolitinib, it was zero. CONCLUSION: The combination of Ruxolitinib and CS for treating IPS post-allo-HSCT suggested promising results in the case series, with favorable response and improved survival by blocking the cytokine production contributing to IPS. The significant mortality difference in the systematic review supports the need for innovative treatment approaches, highlighting the potential role of Ruxolitinib in CS-refractory cases. Despite the positive outcomes in the case series, the absence of randomized controlled trials emphasizes the necessity for further research.
