Clinical Outcomes and Complications Following Hip Fusion Conversion to Total Hip Arthroplasty: A Systematic Review and Meta-Analysis.

BACKGROUND: Efficacy, clinical outcomes, and complications following hip fusion conversion to total hip arthroplasty (THA) surgery have been explored in several studies with controversial findings and no consensus. METHODS: Comprehensive search of online databases was performed through December 2022 for prepost clinical trials using MeSH keywords. Harris hip score (HHS), leg length discrepancy (LLD), pain score, and range of motion (ROM) were considered as clinical outcomes along with implant survival and complications. The retrieved studies were assessed for methodologic quality. Weighted mean difference (WMD) with 95% confidence interval (CI) were calculated using random effects meta-analysis taking into account for heterogeneity. Subgroup meta-analysis as well as sensitivity analysis were performed. RESULTS: Findings of meta-analysis on 34 trials showed that HHS increase after THA (WMD: 42.3; 95% confidence interval (CI): 38 to 47). Subgroup analyses indicated that cementless prosthesis, length of arthrodesis <12 years, age <45 years, and studies with good quality have more HHS improvement. The LLD decreased 21 mm (95% CI: 19 to 24 mm) based on 21 trials. The range of motion (ROM) reached to 89 (95% CI: 84 to 95) for flexion, 32 (95% CI: 27 to 37) for abduction, 25 (95% CI: 21 to 29) for adduction, 29 (95% CI: 25 to 33) for external rotation, and 25 (95% CI: 20 to 31) for internal rotation after surgery. The most common complication was heterotopic ossification (14%). CONCLUSION: Conversion of an ankylosed hip to THA leads to improved hip function and leg discrepancy with relatively notable rate of complications. Our findings could provide a framework to guide surgeons and decision makers.

Hip Capsular Repair Results in Improved Patient-Reported Outcomes and Survivorship: A Systematic Review of the Literature.

PURPOSE: To determine whether routine capsular closure following hip arthroscopy for femoroacetabular impingement (FAI) in patients without dysplasia results in improved patient-reported outcomes (PROs) and increased survivorship rates. METHODS: A literature search of the PubMed, Embase, and Cochrane Library databases was performed using the Preferred Reporting for Systematic Reviews and Meta-Analyses guidelines for clinical studies reporting PROs following arthroscopic hip labral repair for FAI. A quality assessment was performed using the Methodological Index for Non-randomized Studies grading system. Inclusion criteria consisted of comparative clinical studies investigating routine capsular closure with nonclosure in patients undergoing hip arthroscopy for the treatment of FAI and labral tears. Exclusion criteria included non-English language, minimum follow-up of less than 2 years after surgery, technique articles, case reports, noncomparative case series of fewer than 10 patients, failure to report surgical technique, absence of postoperative PROs, or partial repair. Data collection included study characteristics, demographics, indications, radiographic metrics, perioperative findings, surgical technique, baseline and most recent PROs, and subsequent surgeries. RESULTS: A total of 531 articles were reviewed, of which 3 were included with 249 hips that underwent capsular repair and 157 hips that underwent capsulotomy with no repair. There were 2 Level III studies and 1 Level II study, with an average The Methodological Index for Non-randomized Studies score of 16.7. All studies cited FAI and labral tear as an indication for surgery. All studies demonstrated improved PROs from baseline to most recent follow-up. Postoperatively, the repair group reported modified Harris Hip Score values ranging from 80.8 to 87, whereas the nonrepair group reported scores ranging from 76 to 81.7. In addition, the repair group reported postoperative Hip Outcome Score - Sports-Specific Subscale values ranging from 68.1 to 9, whereas the nonrepair group reported scores ranging from 65.3 to 76.1. The studies also reported minimal clinically important difference for modified Harris Hip Score, with the repair group reporting percentages ranging from 71 to 100 and the nonrepair group reporting percentages ranging from 52 to 95.6. All 3 studies also observed a lower rate of hip survivorship in the nonrepair group, ranging from 94.6 to 100 in the repair group and 90.8 to 100 in the nonrepair group. There were no significant differences in the rate of revision arthroscopy between groups. CONCLUSIONS: Patients without dysplasia who undergo capsular repair have greater improvements in PROs and greater survivorship rates at early- and mid-term follow-up than patients who do not undergo capsular repair. LEVEL OF EVIDENCE: III, systematic review of level II and III studies.

Patient-Reported Outcomes Improve at 2-Year Minimum Follow-Up After Hip Arthroscopy for Femoroacetabular Impingement Syndrome: A Systematic Review.

PURPOSE: To provide an updated review of recent literature on postoperative outcomes following hip arthroscopy for femoroacetabular impingement syndrome (FAIS), focusing on larger-population studies with a minimum 2-year follow-up published within the last 5 years. METHODS: A literature search of the PubMed, Ovid Medline, Web of Science, and Cochrane databases was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Articles were screened for clinical studies published from 2017 to 2022 with greater than 100 patients and minimum 2-year follow-up. Exclusion criteria included failure to report postoperative patient-reported outcomes (PROs), no preoperative radiographic measurements, and surgery for pathology other than FAIS. Data collection included study characteristics, patient demographics, radiographic findings, intraoperative findings, procedures performed, postoperative PROs, and subsequent surgeries. RESULTS: Nine studies met inclusion criteria. Mean or median patient ages ranged from 32.3 to 41 years, with 4 studies reporting on greater than 50% female patients. Mean preoperative lateral center edge angles and alpha angles ranged from 30.2° to 37° and from 56.2° to 71°, respectively. Labral repairs (range 69.7%-100%) were performed more commonly than debridements (range 0%-26.3%). All studies demonstrated improved PROs at most recent follow-up. Seven studies reported mean or median modified Harris Hip Scores, with preoperative and postoperative values that ranged from 53.1 to 80 and from 67.4 to 100, respectively. Revision hip arthroscopies and conversions to hip arthroplasty ranged from 0.8% to 11.6% and from 0% to 34%, respectively. CONCLUSIONS: All included studies found improvements in PROs after hip arthroscopy for FAIS at a minimum of 2-year follow-up. Conversion to total hip arthroplasty is most common in older patients at minimum 10-year follow-up. LEVEL OF EVIDENCE: Level IV, systematic review of Level I through IV studies.

Periacetabular Osteotomy in Athletes With Symptomatic Hip Dysplasia Allows for Participation in Low-, Moderate-, and High-Impact Sports, With Greater Than 70% Return to Sport for Competitive Athletes: A Systematic Review.

PURPOSE: To systematically review the literature and report the rate of return to sport (RTS) in athletes following periacetabular osteotomy (PAO) for symptomatic hip dysplasia. METHODS: A literature search of the PubMed, Embase, and Cochrane Library databases was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for clinical studies reporting on athletes undergoing PAO surgery for symptomatic hip dysplasia. A quality assessment was performed using the Methodological Index of Non-Randomized Studies (MINORS) grading system. Data collection included study characteristics, demographics, radiographic measurements, rate and timing of RTS, baseline and most recent patient-reported outcomes (PROs), and subsequent surgeries. RESULTS: Six studies met inclusion criteria with 341 patients undergoing PAO. There were 2 level III and 4 level IV studies, with an average MINORS score of 11. Preoperative and postoperative lateral center edge angles ranged from 8° to 18° and 23° to 41.3°, respectively. One study reported solely on dancers with a 63% rate of RTS at 1 year postoperatively. Two other studies reported RTS of 80% and 82% for multiple sports, with slightly lower rates (73% and 78%) in competitive athletes. Three studies demonstrated a comparable distribution of sports participation, from the preoperative to postoperative period, in low-impact (61.4% to 72.1% and 63.7% to 85.7%), moderate-impact (10.3% to 21.0% and 4.3% to 25.4%), and high-impact (8.5% to 17.6% and 5.1% to 10.8%) sports. Three studies reported time to RTS after PAO, ranging from 8.8 to 12.8 months. Of the 3 studies noting reasons for not returning to sport, concerns related to the operative hip ranged from 36.4% to 67%. Of the studies that reported both preoperative and postoperative PROs, improvements in all values were observed, with modified Harris Hip Scores and Hip Disability Osteoarthritis Outcome Scores at most recent follow-up ranging from 81 to 95 and 72 to 93, respectively. CONCLUSIONS: In athletes with symptomatic hip dysplasia undergoing PAO, postoperative participation in low-, moderate-, and high-impact sports was observed, with greater than 70% RTS for competitive athletes. These findings suggest that PAO, with appropriate indications, is an efficacious treatment option in this active patient population with severe dysplasia. LEVEL OF EVIDENCE: Level IV, systematic review of level III and IV studies.

Orthobiologics as an adjunct in treatment of femoroacetabular impingement syndrome: cell-based therapies facilitate improved postoperative outcomes in the setting of acetabular chondral lesions-a systematic review.

PURPOSE: To evaluate studies utilizing orthobiologics in the management of femoroacetabular impingement syndrome (FAIS) to (1) assess the indications for usage, and (2) analyze patient-reported outcome measures (PROM) following treatment. It was hypothesized that orthobiologics would (1) be utilized for symptomatic FAIS in the setting of labral or chondral pathology, and (2) improve PROM at most recent follow-up. METHODS: The Pubmed, Ovid Medline, Cochrane, and Web of Science databases were searched for clinical studies evaluating orthobiologics [hyaluronic acid (HA), platelet-rich plasma (PRP), or cell-based therapy (CBT) for treatment of FAIS. Exclusion criteria included orthobiologics used in conjunction with cartilage transfer or scaffolding procedures and a primary indication other than FAIS. Data collection included patient demographics, indications, and baseline and most recent PROM. RESULTS: Eleven studies (one level I, four level II, four level III, and two level IV evidence) met inclusion criteria, consisting of 440 patients with mean ages ranging from 32.8 to 47 years. All 11 studies demonstrated an improvement in PROM from baseline to most-recent follow-up. Four studies administered PRP either intraoperatively or the day after surgery as an adjunct to labral repair. CBT was used intraoperatively in the setting of acetabular chondral lesions (three studies) and labral repair (one study). When comparing to a control group at most recent follow-up, three PRP cohorts demonstrated similar PROM (n.s.), while one PRP group exhibited worse visual analog pain scores (2.5 vs. 3.4, p = 0.005) and modified Harris Hip Scores (mHHS) (82.6 vs. 78.7, p = 0.049). The four CBT studies reported favorable results compared to a control group, with a significantly higher mHHS at most recent follow-up or mean improvement from baseline in Hip Outcome Score-Activities of Daily Living (p < 0.05). Three studies reported on HA, which was utilized exclusively in the nonoperative setting. CONCLUSIONS: Intraoperative PRP and CBT have been commonly reported in the setting of hip arthroscopy for labral repairs and acetabular chondral lesions, respectively. The CBT cohorts demonstrated more favorable PROM at most recent follow-up when compared to a control group, though these results should be interpreted with caution due to heterogeneity of orthobiologic preparations. LEVEL OF EVIDENCE: IV.

Challenging the food waste hierarchy.

Food waste is a multi-faceted and complex problem for urban circular economies with far-reaching environmental impacts. Effectively addressing this problem requires a comprehensive understanding of the food waste impacts on food, energy, water, and climate (FEWC) systems. Despite complex dynamics in the FEWC nexus, the most popular guidance for food waste management is the food waste hierarchy framework - which fails to account for ensuing impacts on all nexus elements. Aiming to optimise the framework, we adopt a participatory approach to develop the first comprehensive and replicable system dynamics model of the FEWC footprints of urban food waste throughout the agri-food supply chain. The quantitative model compares different food waste management options, and relevant policies in Bristol, UK (2018-2030). Unlike the guidance of the traditional waste hierarchy framework, our findings show that the preferability of each option can vary for each sector within the supply chain and for each FEWC element. Our results show that increasing food surplus redistribution in the supply sectors and reducing food waste in consumer sectors are the most preferable approaches to reduce the environmental impacts of food. Feeding food leftover to pets at household level also has a promising impact. Other options involve trade-offs between energy and carbon footprints, while having minimal impact on water footprint. We conclude that the traditional food waste hierarchy is too simplified to provide reliable guidance for environmentally sustainable food waste management and policy. Instead, we present an improved food waste hierarchy framework that accounts for the scale of preferability of each option for different sectors and different FEWC nexus elements. This novel framework thus provides more nuanced and more robust understanding of food waste impacts on the FEWC nexus in urban circular economies, thereby enabling the development of policy and management options that are optimised for environmental sustainability.

Menstruation among In-School Adolescent Girls and Its Literacy and Practices in Nigeria: A Systematic Review.

Background and Objectives: Menstruation is a natural occurrence marked by the periodic release of endometrial cells within the uterine lining from the female genital area. Menstruation knowledge remains highly essential for young adolescents. Inadequate awareness and understanding of menstruation have far-reaching consequences on the overall wellbeing and health outcomes of young adults worldwide. Adolescent girls make up a large percentage of high school students in Nigeria. Girls in countries with low to middle incomes are frequently misled or uneducated regarding menstruation. Menstrual health literacy (MHL) is the level of knowledge concerning matters related to menstrual health. It is observed that a lack of menstrual health literacy is seen among young adults. This systematic review aimed to examine menstruation literacy, attitudes, and adolescent girls' practices in Nigeria. Materials and Methods: This systematic review included quantitative, cross-sectional, quasi-experimental, and qualitative primary research studies relating to menstruation literacy, attitudes, and practices of adolescents in Nigeria. Articles for this study were searched for on databases such as PubMed and BioMed Central using keywords. These studies were subjected to stringent inclusion and exclusion criteria where the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used, and 13 articles were included after critical appraisal. Data extracted were analysed using narrative synthesis. Results: Findings indicated that knowledge regarding menstruation among adolescents (82.6%) was poor. Menstruation information was obtained from mothers, which was positive as some adolescents reported their closeness to their mothers. Regarding attitudes towards menstruation among adolescents, it was reported that more respondents (70.3%) had negative attitudes towards menstruation. Conclusions: Most of the respondents in Nigeria were not adequately prepared for the onset of their first menstrual period. Knowledge and attitude levels were low regarding periods for adolescents. The only exception was their positive attitude towards using water and soap to wash their hands during menstruation. The review shows a significant gap between adolescents' menstruation knowledge and actual hygienic methods during menstruation. It is therefore required for educational awareness programmes and campaigns to be put in place to educate adolescents about menstruation.

Association between sarcopenia and quality of life among adults aged ≥ 65 years from low- and middle-income countries.

BACKGROUND: Sarcopenia has been associated with a lower quality of life (QoL). However, studies on this association from low- and middle-income countries (LMICs) are scarce. AIMS: To examine the association between sarcopenia and QoL, in a large nationally representative sample of older adults from six LMICs. METHODS: Cross-sectional, community-based data from the WHO study on global ageing and adult health (SAGE) were analysed. Non-severe sarcopenia was defined as having low skeletal muscle mass (SMM) and weak handgrip strength but no slow gait speed, while severe sarcopenia was defined as having low SMM, weak handgrip strength, and slow gait speed. QoL was assessed with the 8-item WHO QoL instrument (range 0-100) with higher scores representing better QoL. Multivariable linear regression analysis was conducted. RESULTS: Data on 14,585 people aged ≥ 65 years were analyzed [mean (SD) age 72.6 (11.5) years; 55.0% female]. After adjustment for potential confounders, compared to no sarcopenia, severe sarcopenia was associated with a significant - 3.37 points [95% CI - 5.56, - 1.18] lower QoL score. Non-severe sarcopenia was not significantly associated with lower QoL. DISCUSSION: The association between sarcopenia and QoL observed in our study may be explained by factors such as functional impairment and disability related with sarcopenia. CONCLUSIONS: In this large representative sample of older adults from multiple LMICs, compared to no sarcopenia, only severe sarcopenia was associated with a significantly lower QoL score. Interventions to prevent or manage sarcopenia among older adults in LMICs may contribute to better QoL in this population.

Primary angiosarcoma of aorta: A systematic review.

PURPOSE: To elucidate the epidemiology, anatomical, presentation, classification, pathology, investigative modalities, management and prognosis of primary angiosarcoma of the aorta. MATERIAL AND METHODS: A systematic review of literature from the database inception to January 2021 in PubMed and Embase, CINAHL and Cochrane Library in accordance to PRISMA was conducted. Retrieval and extraction was performed by two independent reviewers. The hierarchy of the evidence was assessed through the National Institute for Health and Care Excellence Checklist. Data were subjected to pooled prevalence analysis, Kaplan-Meier survival and test of probability using log-rank analysis. This review is registered with International Prospective Register of Systematic Reviews: RD42021231314. RESULTS: 82 studies with n = 123 cases met the inclusion criterion. Abdominal (45%) aorta was the commonest anatomical site with female predominance in ascending aorta (4:1) and aortic arch (2:1). The longest survival was in the ascending aorta and the shortest in the abdominal aorta [540 (interquartile range [IQR], 7-1560 days vs. 180 (IQR, 1-5730 days)], respectively. The overall median survival was 210 days (IQR, 1-5730 days) or 7 months. Lack of metastasis (47%) was a marker of longer survival (p < 0.03) irrespective of other attributes. CONCLUSION: The pathophysiology appears to be a trend of increasing fatigue, fever and weight loss associated with segmental dysfunction of the aorta projecting occlusive or destructive phenotypes. Computed tomography angiography features of volume-occupying, bulky, polypoid (intraluminal), protrusive vegetation, hyper vascular without atherosclerotic lesions are extremely suggestive of PA of the aorta at 5th and 6th decades of life.

A Systematic Review on the Current Trend in Nonsurgical Aesthetic Training for Knowledge, Skill, and Professional Identity Formation.

BACKGROUND: Non-surgical aesthetics is a rapidly growing healthcare domain and lacks pedagogically sound education and training programs. The trainee physicians often participate in short courses which are outside of the scope of an existing postgraduate training program to acquire the necessary knowledge and procedural skills. However, such training programs lack values and interests that shape critical thinking and holistic decision-making, often referred to as professional identity. OBJECTIVES: This systematic review aims to analyze current trends in non-surgical aesthetic clinical education to form knowledge, skills, and professional identity. METHODS: A detailed literature search was conducted in electronic databases-PubMed, Cochrane, Centre for Reviews and Dissemination, and Google Scholar-for relevant studies published between January 2010 and December 2020, with an update in September 2021. RESULTS: Fifty-five articles were identified through electronic searches, among which 40 were selected following a review of the abstracts. Sixteen articles were identified as the best evidence for the detailed and iterative review based on their relevance and fit to the inclusion criteria. Unfortunately, none of the included studies designed their questionnaire based on the Kirkpatrick Model, which is best known for analyzing and evaluating the results of training and educational programs. CONCLUSIONS: This systematic review provides valuable insight into graduate professional identity formation and graduates' readiness for independent clinical practice. Therefore, particular consideration should be given to incorporating these triggers when developing evidence-based postgraduate curricula for non-surgical aesthetics.

Mid-Term Results of Arthroscopic Synovectomy for Pigmented Villonodular Synovitis of the Hip.

PURPOSE: To analyze mid-term outcomes after arthroscopic synovectomy of both diffuse and nodular hip pigmented villonodular synovitis (PVNS). METHODS: This is a retrospective case series of patients that underwent hip arthroscopy for hip PVNS with a single senior surgeon between 2007 and 2016. Inclusion criteria were magnetic resonance imaging evidence, arthroscopic visualization, and/or histologic confirmation of PVNS; and a minimum of 3 years of follow-up. Concomitant pathology such as femoroacetabular impingement also was treated at the time of surgery. Primary outcome measures were recurrence of hip PVNS and the rate of revision hip surgery. Secondary outcomes were complications, visual analog scale pain score, pain relief, and patient satisfaction, and 6 patient-reported outcome measures were collected at latest follow-up. RESULTS: In a case series of 14 patients consisting of 6 (42.9%) male and 8 (57.1%) female patients, the mean operative age was 32.69 ± 12.73 years with a mean follow-up was 6.66 ± 1.87 years. PVNS type was determined intraoperatively: 5 (35.7%) patients had diffuse hip PVNS and 9 (64.3%) had nodular type. There was only 1 case (7.14%) of recurrence that was treated arthroscopically and no cases (0%) progressed to revision open synovectomy or arthroplasty. Mean patient-reported outcome measure scores were notable for a modified Harris Hip Score of 74.08 ± 16.84. The mean visual analog scale pain score decreased by 4.9 ± 1.7, which was significant with a P < .001, with a larger decrease in patients with localized type. CONCLUSIONS: This study presents a large case series of hip PVNS managed arthroscopically with mid-term follow-up of slightly over 6.5 years. The survival rate was 93%, with only 1 (7%) recurrence and 0 (0%) progression to revision open synovectomy or arthroplasty with 0 (0%) complications. We conclude that arthroscopic synovectomy is a reliable and effective treatment of hip PVNS. LEVEL OF EVIDENCE: Case Series, Level IV.

A systematic review of distal revascularization and interval ligation for the treatment of vascular access-induced ischemia.

OBJECTIVE: Vascular access-induced ischemia remains a rare but significant complication of arteriovenous fistulas. Distal revascularization and interval ligation (DRIL) is one form of treatment. However, its collated efficacy through a systematic review is yet to be established. METHODS: An electronic and systematic search of the literature in MEDLINE, Cumulative Index to Nursing and Allied Health Literature, Embase, and Cochrane Library from 1966 to 2017 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was conducted. Quality assessment of the articles was performed using the Oxford Critical Appraisal Skills Programme, and the recommendation for practice was examined through the National Institute for Health and Care Excellence. Data of treated cases, success, time to ischemia, follow-up, age, sex, diabetes mellitus, fistula type, conduit type, and grade of ischemia were extracted and subjected to a pooled variance-weighted random-effects model. RESULTS: Twenty-two studies (n = 459 individuals) were subjected to DRIL. Time to ischemia was 196 days (interquartile range, 30-600 days). Ischemia grade 3/4 (52%) was the most common presentation. The overall success (grades 1-4) was 81% (95% confidence interval, 80.9%-82.5%) during a mean and median follow-up of 22.2 months (interquartile range, 1-60 months) and 18 months, respectively. The conduit of choice was the great saphenous vein (n = 300/459 [65%]), and bypass thrombosis was highest in the polytetrafluoroethylene group (n = 19/44 [43%]). CONCLUSIONS: DRIL with adequate long-term outcomes is an effective technique for the treatment of vascular access-induced ischemia.

Mid-term outcomes of arthroscopic-assisted Core decompression of Precollapse osteonecrosis of femoral head-minimum of 5 year follow-up.

BACKGROUND: Osteonecrosis of the femoral head (ONFH) is a progressive disease that leads to collapse and the development of secondary arthritis. The preferred management of ONFH remains controversial. Arthroscopic-assisted management of ONFH is a new and evolving approach for hip preservation. We hypothesis that arthroscopy is able to improve ONFH outcomes by achieving accurate and minimally invasive decompression while successfully addressing concomitant intraarticular pathologies resulting in reliable mid-term outcomes. METHODS: This was a retrospective cohort analysis. All patients had atraumatic ONFH with a precollapse lesion and a minimum follow-up of 5 years. RESULTS: A total cohort of 11 hips (8 patients) was identified. The mean patient follow-up was 7 years ±1.48 years (range, 64-118 months). The Ficat-Alret classification found on preoperative imaging was Stage I-3 (27.2%), IIa-4 (36.4%), and IIb-4 (36.4%) hips. Four (36.4%) hips experienced mechanical issues, including locking, catching, and buckling. The most common concomitant pathology addressed at the time of arthroscopy, was labral repair/debridement-8 (73%), followed by microfracture-7 (64%). At final follow-up, 6 hips (54.5%) had not converted to THA. Upon further stratification, Stage I-100%, Stage IIa-75%, for a combined 87%, had not converted to THA, in contrast, 100% of hips categorized as Stage IIb had converted to THA. Ficat-Alret staging, especially Stage IIb, was significantly associated with conversion to THA. (p-value = 0.015) There were 0% major or minor complications. CONCLUSIONS: To our knowledge, this is the longest reported follow-up of arthroscopic-assisted management of ONFH. Arthroscopic-assisted management is a promising surgical approach that provides safe, accurate, and minimally invasive decompression, resulting in reliable results with an acceptable conversion rate to THA. LEVEL OF EVIDENCE: Level IV, Case Series.

The effect of limited access to antenatal care on pregnancy experiences and outcomes among undocumented migrant women in Europe: a systematic review.

Women who are undocumented migrants in Europe encounter a variety of challenges while trying to access health services, including restricted access to antenatal care (ANC) despite the importance of ANC to the well-being of mothers and their infants. This study's aim was to examine the effect that limited access to antenatal care has on the pregnancy experiences and outcomes of undocumented migrant (UM) women in Europe. Systematic searches were done on PubMed, Ovid MEDLINE, Ovid EMBASE, EBSCO CINAHL Plus, and BioMed Central. From the search results, only primary research articles that reported on the pregnancy outcomes and experiences of undocumented migrants were selected. A meta-analysis was not possible because this review included information from both qualitative and quantitative studies. The data that was taken from the included publications was organised, analysed, using the Microsoft Excel programme, and then meta-synthesised. Twelve papers from seven different European nations-Belgium, France, Sweden, Denmark, Norway, Finland, and England-were included in this systematic review. Eight of the studies aimed to explore the access to and utilization of ANC by undocumented migrant women and the related pregnancy outcomes. Two of the included studies examined the pregnancy experiences of UMs and two examined the perinatal risks associated with living as a migrant with no legal status. Although heterogeneous in their specific findings most of the studies showed undocumented immigrants are more likely to experience unfavourable pregnancy outcomes and experience greater anxiety and worries due to a variety of factors than documented migrants and registered citizens. This review's conclusions demonstrate the pressing need for policy modifications and healthcare reforms in Europe to address the problems associated with undocumented migrants' restricted access to antenatal care. It also highlights the urgent need for structural changes that will give this vulnerable population's health and well-being a higher priority. It is not just an issue of health equality but also a humanitarian obligation to address the many obstacles and difficulties undocumented migrant women endure during pregnancy.

Slightly reduced early subsidence with similar outcomes and complications rate in collared stems - A systematic review of randomized clinical trials.

Background: There is a growing trend towards using femoral stems with a medial calcar collar during total hip arthroplasty (THA). Purpose: Systematically review the literature comparing a femoral collared stem and femoral collarless stem on subsidence, patient-reported outcomes (PROs), and revision rate. Study design: Systematic Review, Level of Evidence 1. Methods: A literature search of Pubmed and Medline was according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized controlled trials that evaluated collared and collarless stems, subsidence and PROs for adult patients undergoing total hip arthroplasty (THA) were included. Additional data collection included patient demographics, stem-calcar contact, canal-fill ratio (CFR), stem orientation, surgical approach, Dorr Type, complications, and revisions. Results: Five studies met inclusion criteria. 674 patients (704 hips) were included. Mean patient ages ranged 58.5-72.4 years old, and mean BMI ranged 26.6-29.8 kg/m2. Mean reported follow-up of the included clinical trials ranged 1-9.6 years. Two studies reported mean early subsidence at two weeks postoperatively, which was 0.36, 0.99 mm for collared stems and 0.52, 3.22 mm for collarless stems, proving to be statistically significant (P = 0.023), (P = 0.05). All studies demonstrated improved PROs at most recent follow-up. Revision rates ranged from 4 to 11.3 %, but these were not statistically significant. Conclusions: Implantation of collared stems compared to collarless may reduce early post-operative subsidence, while no substantial effect on aseptic loosening, thigh pain, proximal femoral fracture, and revision is seen. When measuring patient-reported outcomes, the collared femoral stem was not superior to the collarless femoral stem as both resulted in similar improvement preoperatively to postoperative state.
