Translation, cross-cultural adaptation, and validation of the Persian version of the Hospital for Special Surgery Anterior Cruciate Ligament Postoperative Satisfaction Survey.

PURPOSE: With over 140 million speakers spread across Iran, Afghanistan, and Tajikistan, Persian, also known as Farsi, is a pluri-centric language. The purpose of this study is to perform cross-cultural adaptation and examine the validity and reliability of the Persian translation of the Hospital for Special Surgery Anterior Cruciate Ligament Post-Operative Satisfaction Survey (HSS ACL-SS). METHODS: In this retrospective study, 102 anterior cruciate ligament reconstruction (ACLR) patients were asked to complete the Persian version of the HSS ACL-SS, Tegner scale, Lysholm score, the Single Assessment Numeric Evaluation (SANE) score, the Cincinnati Knee Rating System (CKRS), and the Visual Analogue Scale (VAS) for pain. Internal consistency was calculated via Cronbach's alpha coefficient. Validity was assessed with the correlations of Spearman's rho. 18 patients were included in the test-retest reliability assessment. The floor and ceiling effects of the examined content validity of HSS ACL-SS. RESULTS: The Cronbach's alpha coefficient was computed at 0.959, showing outstanding internal consistency. The intra-class correlation coefficient (ICC) demonstrated excellent results (0.986, P-value < 0.001). Insignificant ceiling effects (2.9%) and floor effects (3.9%) were detected. The Persian version of the HSS ACL-SS score significantly correlated with the SANE (r = 0.730, p < 0.001), Lysholm score (r = 0.622, p < 0.001), and CKRS (r = 0.741, p < 0.001). CONCLUSION: The overall performance of the Persian HSS ACL-SS was more than excellent in terms of reliability and validity. To conclude, Persian HSS ACL-SS may be used to assist patients in having a better perception of post-operative satisfaction.

Initiating chemotherapy in joint arthroplasty patients increases the risk of periprosthetic joint infections.

BACKGROUND: Total Joint Arthroplasties (TJAs) are becoming more popular, resulting in a growing economic burden due to potential postoperative complications, with periprosthetic joint infections (PJIs) playing a significant role. The effect of immunosuppression on PJI risk, particularly in cancer patients following chemotherapy, is unknown. The hypothesis of this study investigated whether chemotherapy increases PJI rates in patients who received post-arthroplasty chemotherapy within one year of surgery. METHODS: Data from the M161Ortho dataset of PearlDiver patient records database were utilized using ICD-9, ICD-10, and CPT codes. The cohort includes Total Knee Arthroplasty (TKA), Total Hip Arthroplasty (THA), and Total Shoulder Arthroplasty (TSA) patients who underwent post-arthroplasty chemotherapy within one year after surgery between 2010 and 2022. Patients in the matched control group did not receive post-arthroplasty chemotherapy. Pre-arthroplasty chemotherapy recipients, PJI, and post-op first year revisions were excluded. Analyses including the linear logistic regression were performed via R statistical software. RESULTS: Totally, 17,026 patients (8,558 TKAs, 6,707 THAs, and 1,761 TSAs) were included. At two (OR = 1.59, p = 0.034), three (OR = 1.57, p = 0.009), and four (OR = 1.40, p = 0.032) years for TKA, and two (OR = 2.27, p = 0.008), three (OR = 2.32, p < 0.001), and four (OR = 2.25, p0.001) years for THA, PJI rates were significantly higher in the chemotherapy group. TSA patients had a significant rise in PJI after four years (OR = 2.20, p = 0.031). CONCLUSIONS: This study reveals a possible relationship between postoperative chemotherapy and an increased incidence of PJI in patients with arthroplasty. Chemotherapy suppresses the immune system, rendering patients more vulnerable to infections. Additional research is required to confirm these findings.

Robotic assisted Total Knee Arthroplasty (TKA) is not associated with increased patient satisfaction: a systematic review and meta-analysis.

PURPOSE: Total knee arthroplasty (TKA) is a common orthopedic surgery, yet postoperative dissatisfaction persists in around 20% of cases. Robotic total knee arthroplasty (rTKA) promises enhanced precision, but its impact on patient satisfaction compared to conventional TKA remains controversial (cTKA). This systematic review aims to evaluate patient satisfaction post-rTKA and compare outcomes with cTKA. METHODS: Papers from the following databases were identified and reviewed: PubMed, Scopus, Web of Science, and the Cochrane Online Library, using keywords like "Knee replacement," "Total knee arthroplasty," "Robotic," and "Patient satisfaction." Extracted data included patient satisfaction measures, Knee Society Score, Oxford Knee Score, Forgotten Joint Score, SF-36, HSS, and KOOS. Statistical analysis, including odds ratio and 95% CI was performed using R software. Heterogeneity was assessed using Cochrane's Q test. RESULTS: The systematic review included 17 articles, involving 1148 patients (571 in the rTKA group and 577 in the cTKA group) assessing patient satisfaction following rTKA. An analysis of proportions reveals rTKA satisfaction rate was 95%, while for cTKA, it was 91%. A meta-analysis comparing rTKA and cTKA found no statistically significant difference in patient satisfaction. Additionally, various patient-reported outcome measures (PROMs) were examined, showing mixed results across different studies and follow-up periods. CONCLUSIONS: The results of this study found no difference in patient satisfaction outcomes in the short to mid-term for rTKA compared to conventional methods. This study does not assert superiority for the robotic approach, highlighting the need for careful consideration of various factors influencing outcomes in knee arthroplasty.

Total Hip Arthroplasty in Patients Who Have Crowe Type IV Developmental Dysplasia of the Hip: A Systematic Review.

BACKGROUND: Developmental dysplasia of the hip (DDH) is one of the principal causes of secondary hip osteoarthritis, giving rise to considerable pain, impaired mobility, and a reduced quality of life. The optimal approach to managing individuals who have Crowe-type IV DDH remains controversial. This study aimed to review the existing literature on the application of total hip arthroplasty (THA) as a treatment modality for Crowe-type IV DDH, assessing its efficacy in addressing this severe hip deformity. METHODS: A comprehensive search across the PubMed, Scopus, and Web of Science databases identified relevant studies. Inclusion criteria encompassed investigations reporting outcomes of THA in Crowe-type IV DDH patients. Data extraction and quality assessment were performed independently by two reviewers. Utilizing R software, the prevalence of THA complications was analyzed through proportion analysis, employing the inverse variance method. RESULTS: In this systematic review, a total of 74 studies were included, comprising a collective sample size of 2,829 patients (3,356 hips) diagnosed with Crowe-type IV DDH. The posterior/posterolateral approach was the most commonly utilized surgical approach, followed by the lateral Hardinge and direct lateral approaches. The majority of studies have employed subtrochanteric osteotomies. Notably, post-THA, leg length discrepancy (LLD) decreased, Trendelenburg sign resolved, and back pain reduced. Patient-reported outcome measures like the Harris Hip Score (HHS) improved significantly. The pooled prevalence rates of major postoperative complications were also assessed, including dislocation (7.2%), revision (8.7%), intraoperative fractures (10.5%), loosening (5.7%), nerve paralysis (5.6%), deep vein thrombosis (3.6%), infection (3.8%), heterotopic ossification grade 2 and above (6.1%), and a complicated patient rate of 11.0%. CONCLUSION: Synthesizing diverse study data, an overview of THA's performance emerges, demonstrating significant enhancements in function, pain reduction, quality of life, and the correction of substantial LLD. While THA has shown positive outcomes, instances of complications have been reported. The decision to undergo THA should involve a collaborative assessment between the surgeon and the patient, considering potential benefits and complications.

Shoulder Arthroplasty After Previous Nonarthroplasty Surgery: A Systematic Review and Meta-Analysis of Clinical Outcomes and Complications.

BACKGROUND: Many patients who undergo shoulder arthroplasty (SA) have had at least 1 nonarthroplasty shoulder surgery before the surgery. There is conflicting evidence regarding the effects of previous shoulder surgery on the outcome of SA. A systematic review was conducted to compare functional outcomes and complications between SA patients with and without prior non-SA surgery on the ipsilateral shoulder. METHODS: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and searched MEDLINE/PubMed, Embase, Scopus, and Web of Science comprehensively from inception to January 2023. Based on 9,279 records reviewed, 26 comparative studies were included in the meta-analysis consisting of 5,431 shoulders with prior nonarthroplasty procedures (cases) and 55,144 shoulders without previous surgery (controls). Variables such as functional scores, complications, and range of motion were compared between cases and controls using Review Manager Software. In addition, subgroup analysis was conducted based on prior surgery type (rotator cuff repair [RCR], open reduction and internal fixation [ORIF], soft tissue repairs, and not specified) and type of SA (hemiarthroplasty, anatomical total shoulder arthroplasty, and reverse total shoulder arthroplasty [RTSA]). The results were presented as odds ratios (ORs) or standardized mean differences (SMDs). RESULTS: Except for a higher rate of periprosthetic joint infection (PJI) in patients who had undergone previous arthroscopic surgery (OR, 2.58; 95% confidence interval [CI], 1.66-4.01; p < 0.01), a higher rate of complications was only observed in patients with previous ORIF. These complications included aseptic loosening (OR, 3.43; 95% CI, 2.14-5.50; p < 0.01), shoulder dislocation (OR, 2.25; 95% CI, 1.05-4.84; p = 0.04), overall complication (OR, 3.95; 95% CI, 2.38-6.55; p < 0.01), and revision (OR, 2.52; 95% CI, 1.28-4.97; p = 0.01). Patients with a history of previous surgery demonstrated inferior functional outcomes in comparison with the control group, including American Shoulder and Elbow Surgeons (SMD, -0.39; 95% CI, -0.51 to -0.27; p < 0.01; I2 = 36%), Constant-Murley score (SMD, -0.34; 95% CI, -0.44 to -0.24; p < 0.01; I2 = 0%), abduction (SMD, -0.26; 95% CI, -0.45 to -0.08; p = 0.01; I2 = 54%), and flexion (SMD, -0.33; 95% CI, -0.46 to -0.21; p < 0.01; I2 = 40%). Subgroup analysis by previous type of surgery was not possible regarding functional outcomes. CONCLUSION: Patients who have had prior fracture surgery are at a higher risk of complications, reoperations, and revisions after SA than controls. The normal shoulder anatomy may be disrupted by prior surgery, which makes arthroplasty technically challenging, particularly when it comes to soft tissue balance. On the other hand, RCR before SA did not negatively affect clinical outcomes after RTSA and did not have a higher rate of overall complications (except PJI). LEVEL OF EVIDENCE: Level III (Treatment Studies). See Instructions for Authors for a complete description of levels of evidence.

Illicit drug abuse and complexity of tibial shaft fracture based on AO/OTA classification: Is there any connection?

Purpose: Illicit drug abuse is a global epidemic afflicting millions worldwide. Several studies have investigated the contribution of this dependence as a risk factor for fracture, but its impacts on fracture severity have been rarely studied. The present study primarily aims to determine the relationship between illicit drug abuse and the severity of tibial shaft fractures. Methods: This retrospective study consecutively included patients aged ≥18 years with tibial shaft fracture who attended Sina Tertiary Hospital, Tehran, Iran, between 2016 and 2021. The fracture patterns were assessed according to the Arbeitsgemeinschaft für Osteosynthesefragen Foundation/Orthopaedic Trauma Association classification. Participants were divided into three individual specialists into groups: simple (A), wedge (B) and multifragmentary (C) fractures. The association of illicit drug abuse and other recorded variables, including age, sex, body mass index (BMI), comorbidities, physical activity, smoking habits and mechanism of injury, was also examined and assessed in multivariate logistic regression. Results: Of 219 patients, 26 were drug abusers, and 193 had no history of use. A total of 20 out of 26 drug abusers experienced a complex fracture, yielding a rate of 76.9%, while this rate for nonusers was 50.3% (97 out of 193), indicating a statistically significant difference between the two subgroups (p = 0.011). The smoking history also influenced the fracture pattern (p = 0.027) based on univariate analysis; however, using adjusted multivariate analysis yielded only illicit drug abuse (odds ratio = 3.495; confidence interval = 1.144-10.680) as a risk factor for more complex fractures. Conclusion: The evidence from this study suggests that complexity and fracture patterns can depend on illicit drug abuse history. Level of Evidence: Level III.

Factors associated with postoperative quality of life in patients with intertrochanteric fracture.

Introduction: Intertrochanteric fractures, which make up the majority of hip fractures, are a common and serious injury that can greatly impact quality of life. Treatment of such fractures comprises nearly half of the costs contributed to hip fractures. Identifying the factors affecting the functional outcomes of patients after intertrochanteric fracture can help to reduce burden of disease for the patient and healthcare system. The present study investigated the factors underlying the worsening of short form-36 score (SF-36) scores for intertrochanteric fracture patients. Materials and methods: This retrospective cohort study was designed based on data from our clinic. All consecutive patients with intertrochanteric fractures from November 2016 to September 2020 were reviewed. The exclusion criteria included patients having a second injury or having had previous surgery related to the hip and those with incomplete data. Baseline characteristics of patients were extracted from annotated records. The lab data were acquired from the electronic hospital system. The outcomes were SF-36 scores obtained by phone contact with patients or their families. Statistical analysis was conducted in SPSS. Results: A total of 310 patients were included in the current study. The female gender, advanced age, history of diabetes, thyroid malfunction, cancer, osteoporosis, anticoagulant use and blood transfusion were identified as risk factors for lower SF-36 scores. Low levels of haemoglobin before surgery, blood urea nitrogen (BUN), BUN/Creatinine, and white blood count values correlated with lower SF-36 scores. Conclusion: Numerous contextual variables affected the functional outcomes of the patients. Consideration of these factors could be helpful in reducing costs and improving the quality of life for intertrochanteric fracture patients.

Antibiotic-Coated Intramedullary Nailing Managing Long Bone Infected Non-Unions: A Meta-Analysis of Comparative Studies.

Long bone infected non-unions are such an orthopedic challenge that antibiotic-coated intramedullary nailing (ACIN) has become a viable therapeutic option for their management. This study aims to provide a comprehensive assessment of the available data about the use of antibiotic-coated nailing in the treatment of long bone infected non-unions. Following the PRISMA guideline in this meta-analysis, a systematic literature search was conducted across major databases for studies evaluating ACIN in long bone infected non-unions. The primary outcome measures included union rates, infection control, complications and functional status. Five eligible studies encompassing 183 patients in total met the inclusion criteria. The meta-analysis revealed no difference in the union rate in the antibiotic-coated intramedullary nailing group compared to that of the control group (OR = 1.73 [0.75-4.02]). Antibiotic-coated intramedullary nailing demonstrated no association with higher infection eradication (OR = 2.10 [0.97-4.54]). Also, functional outcome measure was mostly not significantly different between ACIN and control interventions. According to this meta-analysis, compared to the management of controls, ACIN is neither linked to increased union rates nor decreased infection rates. The paucity of research on this topic emphasizes the continuous need for additional well-designed randomized controlled trials for the application of antibiotics-coated intramedullary nailing in long bone non-unions.

Association between ELMO1 gene polymorphisms and diabetic kidney disease: A systematic review and meta-analysis.

BACKGROUND: Previous research has suggested that the ELMO1 gene may play a role in the development of diabetic kidney disease. Diabetic kidney disease (DKD) is a serious complication of diabetes and the leading cause of chronic kidney disease and end-stage renal disease (ESRD). OBJECTIVE AND RATIONALE: This study aim was to systematically review and explore the association between ELMO1 gene polymorphisms and diabetic kidney disease. A comprehensive systematic review provides a clear conclusion and high-level evidence for the association between ELMO1 gene and DKD for future application in personalized medicine. METHODS: A comprehensive search of electronic databases, per PRISMA instructions, was conducted in Scopus, EMBASE, Web of Science, and PubMed databases from 1980 to January 2023. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using appropriate models. Subgroup and sensitivity analyses were performed to explore potential sources of heterogeneity and assess the robustness of the findings. RESULTS: A total of 5794 diabetes patients with DKD, 4886 diabetes patients without DKD, and 2023 healthy controls were included in the 17 studies that made up this systematic review. In the investigation of DM (Diabetes Mellitus) with DKD vs. DM without DKD, the susceptibility for DKD for the EMLO1 rs741301 polymorphism indicated a significant difference under the dominant, homozygote, and recessive genetic models. The susceptibility for DKD for the EMLO1 rs1345365, rs10255208, and rs7782979 polymorphisms demonstrated a significant difference under the allele genetic models in the analysis of DM with DKD vs. DM without DKD groups. There was a considerable increase in DKD risk in the Middle East when the population was stratified by the region. CONCLUSION: The findings of the meta-analysis show that there are a significant connection between the EMLO1 rs741301 polymorphism and DKD susceptibility in overall analyses; as well as rs1345365, rs10255208, and rs7782979 polymorphisms; especially in the Middle East region.

Efficacy of trigger point dry needling on pain and function of the hip joint: a systematic review of randomized clinical trials.

OBJECTIVE: The objective of this study was to assess the evidence for the impact of dry needling (DN) on hip pain and function. METHODS: Medline/PubMed, Embase, Scopus, Web of Science and Cochrane CENTRAL databases were searched systematically through June 2022 for randomized clinical trials (RCTs) investigating the impact of DN on hip pain and function. Version 2 of the Cochrane risk-of-bias tool for randomized trials (RoB 2) was used to assess risk of bias. Descriptive analysis was conducted to explain the outcomes and adverse events of DN in hip joint diseases. Meta-analysis was not feasible due to significant heterogeneity. RESULTS: A total of seven eligible studies (including 273 patients) were included out of 2152 screened records. Five studies were in participants with hip osteoarthritis (OA; n = 3), greater trochanteric pain syndrome (GTPS; n = 1) or piriformis syndrome (n = 1); the other two studies were conducted in healthy athletes (n = 2). Two articles assessed changes in participants' short-term visual analog scale (VAS) scores (<1 week), one of which showed that DN significantly reduced pain (P < 0.05). One-week VAS scores were analyzed in three studies, all of which demonstrated reduced scores following DN (P < 0.05). Hip range of motion (ROM) and muscle force were also improved following DN. No serious side effects were reported. CONCLUSION: DN may be safe and effective at relieving hip pain and improving hip function. DN performs significantly better than several different types of control intervention (including sham DN, no treatment, corticosteroid injections and laser). Strong evidence (high degree of certainty around the results) is lacking, and future studies should ideally use longer follow-up periods and larger sample sizes. REVIEW REGISTRATION NUMBER: CRD42022297845 (PROSPERO).

Patient satisfaction following robotic unicompartmental knee arthroplasty: A systematic review and meta-analysis.

BACKGROUND: Unicompartmental knee arthroplasty (UKA) is a viable alternative to total knee arthroplasty (TKA) for osteoarthritis patients with single-compartment involvement, with advantages including accelerated recovery, reduced pain, and improved function. Robotic-assisted UKA (rUKA) is a promising development that ensures precise implant positioning and limb alignment. However, concerns about complications remain. OBJECTIVE: This study looks at patient satisfaction as a key metric for determining the efficacy of rUKA versus manual UKA (mUKA). METHODS: The search strategy for this study followed PRISMA. Using precise keywords, PubMed, Scopus, Web of Science, and the Cochrane library were searched. English articles were searched until August 2, 2023. Selection criteria included mUKA and rUKA patient satisfaction studies. The NOS scale evaluated study quality. Meta-analysis was done with R and heterogeneity analysis. RESULTS: This systematic review examined 5 studies with 1060 UKAs (532 robotic-assisted and 528 manual). Variable satisfaction assessment methods were used. Three studies found no difference in patient satisfaction after robotic-assisted UKA, but two found a higher satisfaction. Meta-analysis showed robotic-assisted UKA improved patient satisfaction (OR = 1.72 [1.25-2.37]). Overall, most studies showed low risk of bias, except one with higher bias. CONCLUSION: This review suggests that robotic assistance may enhance patient satisfaction in UKA procedures.

Cross-Cultural Adaptation and Validation of the Persian Version of the Harris Hip Score.

Background: The Persian language, also known as Farsi, is a pluricentric language spoken in Iran, Afghanistan, and Tajikistan by about 140 million people. This study aims to translate the Harris hip score (HHS) into Persian with cross-cultural adaptation and to evaluate its validity and reliability. Methods: One hundred fifty-six total hip arthroplasty patients completed the Persian version of the HHS, Western Ontario and McMaster Universities Osteoarthritis Index, Forgotten Joint Score, and visual analog scale (VAS) for pain and satisfaction postoperatively. Using Cronbach's alpha (α) coefficient, internal consistency was evaluated. Correlations (Spearman's Rho) were used to assess validity. A test-retest reliability assessment of the Persian HHS was conducted (n = 47) using the intraclass correlation coefficient. Content validity was evaluated using the floor and ceiling effects of the HHS. Results: The final translation of the Persian HHS was approved to be used. The preoperative and postoperative Cronbach's alpha were 0.71 and 0.70, respectively, and showed acceptable internal consistency. The intraclass correlation coefficient was excellent (0.869, P < .001). Insignificant ceiling effects (13.5%) and no floor effects (0) were observed. The HHS score was significantly and strongly correlated with Western Ontario and McMaster Universities Osteoarthritis Index (r = 0.696, P < .001), VAS pain (r = 0.654, P < .001), VAS satisfaction (r = 0.634, P < .001), and Forgotten Joint Score (r = 0.648, P < .001). Conclusions: The Persian HHS demonstrated excellent reliability and validity properties. Accordingly, Persian HHS may be a helpful tool for assessing patients undergoing total hip arthroplasty.

Risk Factors for Dislocation following Total Hip Arthroplasty in Developmental Dysplasia of the Hip: A Systematic Review and Meta-Analysis.

PURPOSE: This systematic review and meta-analysis aimed to identify risk factors of dislocation after total hip arthroplasty (THA) in patients with developmental dysplasia of the hip (DDH). METHODS: A systematic literature review was performed on 18th August 2022 using Medline, Embase, Scopus, Web of Science electronic databases, and a manual search. The study was conducted according to the PRISMA guidelines and registered with PROSPERO. Statistical analysis includes assessment of heterogeneity and data synthesis using RevMan 5.4. RESULTS: Review of five studies including 2865 patients and 116 dislocated hips found that lower body mass index (BMI) (SMD = 0.22, p = 0.04, I2 = 0%), Crowe classification type IV versus I, II, and III (OR = 2.70, p = 0.004, I2 = 51%), higher cup inclination (SMD = 0.39 p = 0.0007, I2 = 0%), femoral head size < 28 mm (OR = 5.07, p = 0.003, I2 = 71%), lateral surgical approach (OR = 1.96, p = 0.02, I2 = 0%), and postoperative infection (OR = 6.26, p < 0.0001, I2 = 0%) were significant risk factors. However, age, gender, cup anteversion, femoral osteotomy, vertical (V-COR) centre of rotation, intraoperative fracture, preoperative and postoperative leg length discrepancy (LLD) and previous hip surgery were not found to be significant risk factors. CONCLUSION: This study underscores importance of these risk factors in THA planning for DDH patients to reduce dislocation risk. Further research needed to understand mechanisms.

Influencing factors on morbidity and mortality in intertrochanteric fractures.

We aimed to evaluate the effect of the patient's clinical and paraclinical condition before and after surgery on short-term mortality and complication and long-term mortality. A retrospective cohort study was conducted and multivariate logistic regression was applied to determine the effect of demographic characteristics (sex, age, AO/OTA classification, height, weight, body mass index), medical history (hypertension, ischemic heart disease, diabetes mellitus, thyroid malfunction, cancer, osteoporosis, smoking) lab data (Complete blood cell, blood sugar, Blood Urea Nitrogen, Creatinine, Na, and K), surgery-related factors (Anesthesia time and type, implant, intraoperative blood transfusion, postoperative blood transfusion, and operation time), duration of admission to surgery and anticoagulant consumption on short-term mortality and complication and long-term mortality. Three hundred ten patients from November 2016 to September 2020 were diagnosed with an intertrochanteric fracture. 3.23% of patients died in hospital, 14.1% of patients confronted in-hospital complications, and 38.3% died after discharge till the study endpoint. ΔNumber of Neutrophiles is the primary determinant for in-hospital mortality in multivariate analysis. Age and blood transfusion are the main determinants of long-term mortality, and Na before surgery is the primary variable associated with postoperative complications. Among different analytical factors Na before surgery as a biomarker presenting dehydration was the main prognostic factor for in hospital complications. In hospital mortality was mainly because of infection and long-term mortality was associated with blood transfusion.

Immunomodulatory actions of vitamin D in various immune-related disorders: a comprehensive review.

For many years, vitamin D has been acknowledged for its role in maintaining calcium and phosphate balance. However, in recent years, research has assessed its immunomodulatory role and come up with conflicting conclusions. Because the vitamin D receptor is expressed in a variety of immune cell types, study into the precise role of this molecule in diseases, notably autoimmune disorders, has been made possible. The physiologically activated version of vitamin D also promotes a tolerogenic immunological condition in addition to modulating innate and acquired immune cell responses. According to a number of recent studies, this important micronutrient plays a complex role in numerous biochemical pathways in the immune system and disorders that are associated with them. Research in this field is still relatively new, and some studies claim that patients with severe autoimmune illnesses frequently have vitamin D deficiencies or insufficiencies. This review seeks to clarify the most recent research on vitamin D's immune system-related roles, including the pathophysiology of major disorders.

Preterm birth does not increase the risk of developmental dysplasia of the Hip: a systematic review and meta-analysis.

BACKGROUND: The purpose of this systematic review was to appraise the literature on the association between preterm birth and developmental dysplasia of the hip (DDH). METHODS: Medline, Embase, Scopus, and Web of Science databases were queried for all studies pertaining to DDH and preterm birth. Data were imported and analyzed in Revman5 and Comprehensive Meta-Analysis (CMA) for pooled prevalence estimation. RESULTS: Fifteen studies were included in the final analysis. There were 759 newborns diagnosed with DDH in these studies. DDH was diagnosed in 2.0% [95%CI:1.1-3.5%] of the premature newborns. Pooled incidence rate of DDH was not statistically different between those groups (2.5%[0.9%-6.8%] vs. 0.7%[0.2%-2.5%] vs. 1.7%[0.6%-5.3%];Q = 2.363,p = 0.307). CONCLUSIONS: In this systematic review and meta-analysis, we did not find preterm birth to be a significant risk factor for DDH. Data suggests that female sex and breech presentation are associated with DDH in preterm infants, but the data is scarce in the literature.

Management of a floating shoulder accompanied by a scapular surgical neck fracture: a case report and review of the literature.

In this article, we want to present a floating shoulder case accompanied by a scapular surgical neck fracture and review the literature about its diagnosis and management. Case Presentation: Our patient was a 40-year-old man who suffered a severe left shoulder injury as a result of a car-to-pedestrian accident. Computed tomography scan revealed a scapular surgical neck and body fracture, a spinal pillar fracture, and a dislocation of the acromioclavicular (AC) joint. The medial-lateral displacement and glenopolar angle were 21.65 mm and 19.8°, respectively. There was a 37° angular displacement and a greater than 100% translational displacement.Initially, the AC joint dislocation was approached via a superior incision on the clavicle and reduced with a single hook plate. A Judet approach was then used to expose the scapula fractures. The scapular surgical neck was fixed with a reconstruction plate. The spinal pillar was stabilized with two reconstruction plates following reduction.Following a year of follow-up, the patient's shoulder range of motion was acceptable, and an American Shoulder and Elbow Surgeons score of 88 was achieved. Discussion and Conclusion: Floating shoulder management is still controversial. Floating shoulders are often treated surgically due to their consequent instability and potential risk of nonunion and malunion. As shown in this article, the indications for operating on isolated scapula fractures may also apply to floating shoulders. A well-planned approach to fractures is also imperative, and the AC joint should always be a priority.

Simultaneous versus staged bilateral total hip arthroplasty: a systematic review and meta-analysis.

BACKGROUND: Total hip arthroplasty is a common orthopedic surgery for treating primary or secondary hip osteoarthritis. Bilateral total hip replacement could be performed in a single stage or two separate stages. Each surgical procedure's reliability, safety, and complications have been reported controversially. This study aimed to review the current evidence regarding the outcomes of simultaneous and staged bilateral total hip arthroplasty. METHODS: We conducted a meta-analysis using MEDLINE, EMBASE, Web of Science, and Scopus databases. Eligible studies compared complications and related outcomes between simultaneous and staged bilateral THA. Two reviewers independently screened initial search results, assessed methodological quality, and extracted data. We used the Mantel-Haenszel method to perform the meta-analysis. RESULTS: In our study, we included 29,551 patients undergoing simBTHA and 74,600 patients undergoing stgBTHA. In favor of the simBTHA, a significant reduction in deep vein thrombosis (DVT) and systemic, local, and pulmonary complications was documented. However, we evidenced an increased pulmonary embolism (PE) and periprosthetic fracture risk in simBTHA. In the simBTHA, total blood loss, length of hospital stay, and total cost were lower. CONCLUSION: This meta-analysis shows that simultaneous bilateral THA accompanies fewer complications and lower total cost. Well-designed randomized controlled trials are needed to provide robust evidence.
