Phenytoin is associated with increased risk of osteoporosis and fragility fractures in adult epileptic patients.

INTRODUCTION: Osteoporotic fractures lead to significant decreases in the quality of life with increases in morbidity, mortality, and disability. Treatment with a variety of anti-epileptic drugs, such as phenytoin, has been understood to cause a decrease in bone mineral density. MATERIALS AND METHODS: Cohort A was identified as patients that were 18-55 years old that had epilepsy and recurrent seizures that were also prescribed phenytoin. Cohort B was identified as patients that were 18-55 years old that had epilepsy and recurrent seizures but were not prescribed phenytoin or other anti-epileptic medications. Cohorts were matched for relevant confounding pathologies and demographic factors. Outcomes were evaluated from 1 day to 5 years after the indexed event. RESULTS: A total of 35,936 patients with epilepsy that were prescribed phenytoin were matched with 109,335 patients with epilepsy that were not prescribed phenytoin. Patients on phenytoin therapy were at significantly higher risk for osteoporosis without pathological fracture, fracture of metatarsal bone, fracture of shoulder and upper arm, fracture of distal radius, fracture of thoracic vertebra, fracture of cervical vertebra, fracture of lumbar vertebra, fracture of femoral head or neck, pertrochanteric fracture, femoral shaft fracture, and distal tibia fracture (all outcomes p < 0.001). CONCLUSION: Epileptic patients on phenytoin therapy that were 18-55 years old exhibited higher associated risk of osteoporosis and osteoporotic-fragility fractures of various regions. Patients that undergo phenytoin therapy for epilepsy treatment should be educated on the increased risk of bone fractures and have appropriate lifestyle and diet modifications.

Risk Factors Associated With Postoperative Cardiac Events Following Total Hip and Knee Arthroplasty.

BACKGROUND: This study investigated the prevalence of adverse cardiac events following a total joint arthroplasty and subsequently analyzed risk factors that may increase the likelihood of these events. METHODS: Data for this study were extracted from a large national database. Chi-squared analyses and multivariate modelings were performed to determine the risk factors associated with 30-day perioperative troponin elevation, myocardial infarction (MI), and heart failure. We identified 80,544 total hip arthroplasty (THA) patients and 112,531 total knee arthroplasty (TKA) patients and analyzed the following cardiac risk factors: diabetes, renal insufficiency, prior MI, hypertension, and cerebrovascular disease. RESULTS: There were 34% of THA patients and 52% of TKA patients who had at least one of the studied risk factors. At-risk THA patients had 2.2, 5.9, and 5.3 times the odds of troponin elevation, MI, and postoperative heart failure, respectively, within 1 month compared to the control group (P < .0001). The TKA group had 2.9, 5.3, and 5.9 times the odds of troponin elevation, MI, and postoperative heart failure within 1 month compared to the control group (P < .0001). For both procedures, prior MI had the highest odds of resulting in perioperative troponin elevation and MI. Renal insufficiency had the highest odds of resulting in perioperative heart failure. CONCLUSIONS: Risk stratification for postoperative complications in orthopedic surgery is important to minimize adverse outcomes. This study highlights the need for consideration of risk factors prior to joint arthroplasty surgery. LEVEL OF EVIDENCE: Level III, Prognostic.

Publication Trends of Residents Accepted for Shoulder and Elbow Fellowships.

This study aims to evaluate the research productivity trends in orthopaedic residents who were selected for shoulder and elbow fellowships from 2010 to 2019. We hypothesize that residents matching into orthopaedic shoulder and elbow fellowships are increasing both their publication number and publication quality from 2010 to 2019. Fellows of orthopaedic shoulder and elbow programs from 2010 to 2019 were identified through publicly accessible information on fellowship programs. Each fellow's publication data during their residency was collected via publicly available search engines, and analyzed to include: fellowship year, residency years, fellowship program and location, total publications, number of publications in high-impact general orthopaedic and shoulder and elbow journals, and authorship position. A total of 176 orthopaedic shoulder and elbow fellows from 17 different programs were identified and included in the study. The fellows produced a total of 668 publications, published 172 articles in high impact journals, and had first authorship on 49% of the studies. On average, there were 3.8 publications per fellow per year from 2010 to 2019. There were 5.7 publications produced per fellow in 2018-2019, compared to just 2.92 publications per fellow in 2010-2011. Overall, there was an increasing trend in publications, publications in high impact journals, and first authorship publications per applicant matching into shoulder and elbow fellowship from 2010 to 2019.

Editorial Commentary: Mesenchymal Stem Cells in the Shoulder Subacromial Bursa: Do Cells Understand Statistical Significance?

Local, arthroscopic harvest of mesenchymal stem cells is of interest due to their potential to augment healing. The high rates of retear after rotator cuff repair are a significant concern, and solutions, such as augmentation with mesenchymal stem cells, are being sought. The subacromial bursa of the shoulder is a potential source of cells to augment healing.

Editorial Commentary: Neuropathy After Fascia Iliaca Blocks for Hip Arthroscopy: Should We Just Blame Anesthesia?

Hip arthroscopy has been the subject of recent controversy in the literature with regard to outcomes and complications. The current investigation demonstrates a significant increase in the risk of postoperative medial thigh neuropathy with fascia iliaca block. Although the association between lateral thigh and groin numbness with traction and anterior portal instrumentation cannot be ruled out, this investigation begs the question: Should we just blame anesthesia? Probably not, as regional blocks, portal placement, and traction are all likely to play some role.

Editorial Commentary: Posterior Cruciate Ligament Femoral Techniques: The "Critical Corner" Is Just Not as Exciting as the "Killer Turn".

The "killer turn" between the graft and tibial tunnel in posterior cruciate ligament reconstruction has always been of technical and clinical importance. The "critical corner" of the graft and femoral tunnel has garnered less interest. Technical advances in arthroscopic instrumentation have allowed a move from inside-out to outside-in techniques, which can assist with tunnel placement and drilling. While these techniques do not impact the "killer turn," they have been demonstrated to decrease the acuity of the "critical corner," but there remains no evidence of impact on graft rupture or clinical outcomes.

Editorial Commentary: Technical Advances in Fixation for Arthroscopic Anterior Cruciate Ligament Reconstruction Won't Take the Place of Good Technique Or a Strong Arm!

Advances in fixation technology have improved the time-zero stability of grafts used for anterior cruciate ligament reconstruction, but the clinical impact of this is unclear. Adjustable-loop-length devices are the latest iteration of cortical fixation and offer retensioning of the graft after tibial fixation. This capability is absent in traditional closed-looped devices and interference screws, but there are concerns with the adjustable mechanism maintaining tension with cyclic loading. Although this advance may represent an additional tool for fine-tuning graft tension, it does not replace good technique in the use of anterior cruciate ligament fixation devices.

The use of a lot quality assurance sampling methodology to assess and manage primary health interventions in conflict-affected West Darfur, Sudan.

BACKGROUND: Organizations working in conflict-affected areas have a need to monitor and evaluate their programs, however this is often difficult due to the logistical challenges of conflict areas. Lot quality assurance sampling may be a suitable method of assessing programs in these situations. METHODS: We conducted a secondary data analysis of information collected during Medair's routine program management functions. Medair's service area in West Darfur, Sudan was divided into seven supervisory areas. Using the available population information, a sampling frame was developed and interviews were conducted from randomly selected caretakers of children in each supervisory area every six months over 19 months. A survey instrument with questions related to key indicators for immunizations and maternal, newborn, and child health was used for the interviews. Based on Medair's goals for each indicator, decision rules were calculated for the indicators; these decision rules determined which supervisory areas and indicators performed adequately in each assessment period. Pearson's chi-squared tests, adjusted for the survey design using STATA "svy: tab" commands, were used to detect overall differences in coverage in this analysis. RESULTS: The coverage of tetanus toxoid vaccination among pregnant women increased from 47.2 to 69.7 % (p value = 0.046), and births attended by a skilled health professional increased from 35.7 to 52.7 % (p value = 0.025) from the first to last assessment periods. Measles vaccinations declined from 72.0 to 54.1 % (p value = 0.046). The estimated coverage for the proportion of women receiving a postpartum dose of vitamin A (54.7 to 61.3 %, p value = 0.44); pregnant women receiving a clean delivery kit (54.6 to 47.1 %, p value = 0.49); and pentavalent vaccinations (49.7 to 42.1 %, p value = 0.28) did not significantly change. CONCLUSIONS: Lot quality assurance sampling was a feasible method for Medair staff to evaluate and optimize primary health programs in a conflict-affected area. Medair managers were able to collect, analyze, and disseminate data to staff alongside the routine work of the organization. These results suggest LQAS may be used in other complex humanitarian emergencies in which there are logistical challenges and limited resources.

Community-based mental health treatments for survivors of torture and militant attacks in Southern Iraq: a randomized control trial.

BACKGROUND: Systematic violence is a long-standing problem in Iraq. Research indicates that survivors often experience multiple mental health problems, and that there is a need for more rigorous research that targets symptoms beyond post-traumatic stress (PTS). Our objective was to test the effectiveness of two counseling therapies in Southern Iraq in addressing multiple mental health problems among survivors of systematic violence: (1) a transdiagnostic intervention (Common Elements Treatment Approach or CETA); and (2) cognitive processing therapy (CPT). The therapies were provided by non-specialized health workers since few MH professionals are available to provide therapy in Iraq. METHODS: This was a randomized, parallel, two site, two-arm (1:1 allocation), single-blinded, wait-list controlled (WLC) trial of CETA in one site (99 CETA, 50 WLC), and CPT in a second site (129 CPT, 64 WLC). Eligibility criteria were elevated trauma symptoms and experience of systematic violence. The primary and secondary outcomes were trauma symptoms and dysfunction, respectively, with additional assessment of depression and anxiety symptoms. Non-specialized health workers (community mental health worker, CMHW) provided the interventions in government-run primary health centers. Treatment effects were determined using longitudinal, multilevel models with CMHW and client as random effects, and a time by group interaction with robust variance estimation, to test for the net difference in mean score for each outcome between the baseline and follow up interview. Multiple imputation techniques were used to account for missingness at the item level and the participant level. All analyses were conducted using Stata 12. RESULTS: The CETA intervention showed large effect sizes for all outcomes. The CPT intervention showed moderate effects sizes for trauma and depression, with small to no effect for anxiety or dysfunction, respectively. CONCLUSIONS: Both CETA and CPT appear to benefit survivors of systematic violence in Southern Iraq by reducing multiple mental health symptoms, with CETA providing a very large benefit across a range of symptoms. Non-specialized health workers were able to treat comorbid symptoms of trauma, depression and anxiety, and dysfunction among survivors of systematic violence who have limited access to mental health professionals. The trial further supports the use of evidence-based therapies in lower-resource settings. TRIAL REGISTRATION AND PROTOCOL: This trial was registered at ClinicalTrials.gov on 16 July 2010 with an identifier of NCT01177072 as the Study of Effectiveness of Mental Health Interventions among Torture Survivors in Southern Iraq. The study protocol can be downloaded from the following website: http://tinyurl.com/CETA-Iraq-Protocol . In the protocol, the CETA intervention is given a different name: components-based intervention or CBI.

Arthroscopic Excision of a Symptomatic Os Trigonum.

PURPOSE: To report the clinical outcomes of arthroscopic excision for a symptomatic os trigonum initially viewing through the posteromedial ankle portal with the motorized instrument in the posterolateral portal. METHODS: A retrospective review of a consecutive series of patients with symptomatic os trigonum failing nonoperative management and treated with arthroscopic excision was performed. Demographic data, clinical data, American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot scores, and Single Assessment Numeric Evaluation scores were obtained. Any complications and the time required to return to sports or full activities were recorded. RESULTS: Twenty-four patients with an arthroscopic excision of a symptomatic os trigonum were included. There were 13 male and 11 female patients. The average age was 36.7 ± 17 years. Twenty-one isolated os trigonum excisions and 3 excisions combined with other procedures were studied. At a mean follow-up of 26 months (range, 24 to 31 months), average preoperative AOFAS scores significantly improved from 55.3 to 92.3 postoperatively (P < .0001). The preoperative AOFAS function component improved from 17.1 to 33.8 (P < .0001). The mean postoperative Single Assessment Numeric Evaluation score was 90. Patients reported full activity at an average of 1.5 months with no limitations at an average of 7.8 months after surgery. The only complication was a posterior tibial nerve calcaneal branch neurapraxia. CONCLUSIONS: Arthroscopic excision in the prone position without traction of a symptomatic os trigonum viewing initially through the posteromedial portal with a high-speed burr in the posterolateral portal resulted in significantly improved AOFAS scores with a single transient neurapraxia in 24 patients. Patients returned to their normal daily activities without limitations at an average of 1.5 months. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

A comparison of the medium-term impact and recovery of the Pakistan floods and the Haiti earthquake: objective and subjective measures.

INTRODUCTION: The 2010 Haiti earthquake and Pakistan floods were similar in their massive human impact. Although the specific events were very different, the humanitarian response to disasters is supposed to achieve the same ends. This paper contrasts the disaster effects and aims to contrast the medium-term response. METHODS: In January 2011, similarly structured population-based surveys were carried out in the most affected areas using stratified cluster designs (80×20 in Pakistan and 60×20 in Haiti) with probability proportional to size sampling. RESULTS: Displacement persisted in Haiti and Pakistan at 53% and 39% of households, respectively. In Pakistan, 95% of households reported damage to their homes and loss of income or livelihoods, and in Haiti, the rates were 93% and 85%, respectively. Frequency of displacement, and income or livelihood loss, were significantly higher in Pakistan, whereas disaster-related deaths or injuries were significantly more prevalent in Haiti. CONCLUSION: Given the rise in disaster frequency and costs, and the volatility of humanitarian funding streams as a result of the recent global financial crisis, it is increasingly important to measure the impact of humanitarian response against the goal of a return to normalcy.

A Common Elements Treatment Approach for Adult Mental Health Problems in Low- and Middle-Income Countries.

This paper describes the Common Elements Treatment Approach (CETA) for adults presenting with mood or anxiety problems developed specifically for use with lay counselors in low- and middle-income countries (LMIC). Details of the intervention development, training, supervision, and decision-making process are presented. Case vignettes are used as examples throughout. Preliminary findings are presented on counselor/supervisor performance and client outcomes from practice cases completed prior to randomized controlled trials (RCT) conducted at two sites for adult survivors of torture and/or systematic violence in (a) southern Iraq and (b) Thailand-Burma border. Data suggest that local supervisors and lay counselors with little prior mental health training or experience maintained fidelity to the model. The majority of pilot clients were retained in treatment, suggesting acceptability. Using the Reliable Change Index (RCI) for each individual we examined the number of clients above a minimal threshold (z > 1.96) for each outcome. In Iraq 100% of clients had RCIs above the threshold for depression and posttraumatic stress, and 81.8% for impaired function. In Thailand, 81.3% of clients had RCIs above minimum threshold for depression, 68.8% for posttraumatic stress, and 37.5% for impaired function. Implementation of CETA is discussed in relation to cultural issues within LMIC. These findings, combined with US-based evidence, suggest that a common elements approach warrants further development and testing as a means for addressing the treatment gap for mental health problems in LMIC.

Return to Play Rates Following Operative Ankle Fractures Differ Between High- and Low-Performing National Football League Athletes.

This study investigated predictive factors for return to play among National Football League athletes after operative treatment of ankle fractures and the impacts of these injuries on career longevity and player performance. Athletes who underwent surgery to repair ankle fractures from the 2013 to 2017 seasons were identified from injury reserve lists and press releases. Demographics and season metrics were collected before and after the injury. Statistical analysis assessed for differences in recorded variables between injured and uninjured players. Thirty-one players met study inclusion criteria. Twenty-two (71%) athletes successfully returned to play. Players who did not return showed no significant differences (P>.05) in position, age, body mass index, number of games or seasons played preinjury, or snaps per game the season prior to injury and had a significantly lower (42.6%, P=.013) preinjury season approximate value (SAV) compared with returning players. Returning athletes showed no significant differences (P>.05) in SAV or snaps per game compared with their preinjury season or with uninjured controls. A high preinjury SAV is associated with successful return to play. No difference in game time or performance metrics was detectable between returning players and uninjured controls, or between preinjury and postinjury seasons. [Orthopedics. 2024;47(1):22-27.].

Preventing Iatrogenic Fibula Fractures Using the Push-Pull Technique: A Biomechanical Comparison of Unicortical Versus Bicortical Post Screws.

BACKGROUND: Displaced diaphyseal fractures can be reduced using the push-pull technique, wherein a plate is affixed to the distal fragment of the fracture, a post screw is placed proximal to the plate, and a lamina spreader creates distraction. This study evaluated the load to failure and mechanism of failure of bicortical and unicortical post screws during reduction. MATERIALS AND METHODS: Four matched pairs of cadaver legs were subjected to a 2-cm oblique osteotomy simulating a displaced, oblique diaphyseal fracture. A 6-hole compression plate was affixed to the distal fragment with 2 unicortical locking screws, and a 12-mm uni-cortical or 20-mm bicortical screw was inserted as a post screw proximal to the plate. A lamina bone spreader was used to exert a distraction force between the plate and the post screw. A mechanical actuator simulated the distraction procedure until failure. Maximum applied load, displacement, and absorbed energy were recorded and compared across unicortical and bicortical groups by paired t tests. RESULTS: At maximum load, we found statistically significant differences in displacement (P=.003) and energy absorbed (P=.022) between the two groups. All unicortical screws failed through screw toggle and bone cut-out. Bicortical screws failed through bending, with no visible damage to the bone at the screw site. CONCLUSION: When diaphyseal fractures are significantly shortened and require a greater distraction force to achieve reduction, bicortical screws demonstrate a higher mechanical load to failure and increased bone loss from the screw-removal site. A unicortical post screw may be used if minimal distraction is needed. [Orthopedics. 202x;4x(x):xx-xx.].

Mortality in Iraq associated with the 2003-2011 war and occupation: findings from a national cluster sample survey by the university collaborative Iraq Mortality Study.

BACKGROUND: Previous estimates of mortality in Iraq attributable to the 2003 invasion have been heterogeneous and controversial, and none were produced after 2006. The purpose of this research was to estimate direct and indirect deaths attributable to the war in Iraq between 2003 and 2011. METHODS AND FINDINGS: We conducted a survey of 2,000 randomly selected households throughout Iraq, using a two-stage cluster sampling method to ensure the sample of households was nationally representative. We asked every household head about births and deaths since 2001, and all household adults about mortality among their siblings. We used secondary data sources to correct for out-migration. From March 1, 2003, to June 30, 2011, the crude death rate in Iraq was 4.55 per 1,000 person-years (95% uncertainty interval 3.74-5.27), more than 0.5 times higher than the death rate during the 26-mo period preceding the war, resulting in approximately 405,000 (95% uncertainty interval 48,000-751,000) excess deaths attributable to the conflict. Among adults, the risk of death rose 0.7 times higher for women and 2.9 times higher for men between the pre-war period (January 1, 2001, to February 28, 2003) and the peak of the war (2005-2006). We estimate that more than 60% of excess deaths were directly attributable to violence, with the rest associated with the collapse of infrastructure and other indirect, but war-related, causes. We used secondary sources to estimate rates of death among emigrants. Those estimates suggest we missed at least 55,000 deaths that would have been reported by households had the households remained behind in Iraq, but which instead had migrated away. Only 24 households refused to participate in the study. An additional five households were not interviewed because of hostile or threatening behavior, for a 98.55% response rate. The reliance on outdated census data and the long recall period required of participants are limitations of our study. CONCLUSIONS: Beyond expected rates, most mortality increases in Iraq can be attributed to direct violence, but about a third are attributable to indirect causes (such as from failures of health, sanitation, transportation, communication, and other systems). Approximately a half million deaths in Iraq could be attributable to the war. Please see later in the article for the Editors' Summary.

Determinants of performance of supplemental immunization activities for polio eradication in Uttar Pradesh, India: social mobilization activities of the Social mobilization Network (SM Net) and Core Group Polio Project (CGPP).

BACKGROUND: The primary strategy to interrupt transmission of wild poliovirus in India is to improve supplemental immunization activities (SIAs) and routine immunization coverage in priority districts. The CORE Group, part of the Social Mobilization Network (SM Net), has been successful in improving SIA coverage in high-risk areas of Uttar Pradesh (UP). The SM Net works through community level mobilisers (from the CORE Group and UNICEF) and covers more than 2 million children under the age of five. In this paper, we examine the reasons the CORE Group had been successful through exploration of which social mobilization activities of the CORE Group predicted better performance of SIAs. METHODS: We carried out a secondary data analysis of routine monitoring information collected by the CORE Group and the Government of India for SIAs. These data included information about vaccination outcomes of SIAs in CORE Group areas and non-CORE Group areas within the districts where the CORE Group operates, along with information about the number of various social mobilization activities carried out for each SIA. We employed Generalized Linear Latent and Mixed Model (GLLAMM) statistical analysis methods to identify which social mobilization activities predicted SIA performance, and to account for the intra-class correlation (ICC) between multiple observations within the same geographic areas over time. RESULTS: The number of mosque announcements carried out was the most consistent determinant of improved SIA performance across various performance measures. The number of Bullawa Tollies carried out also appeared to be an important determinant of improved SIA performance. The number of times other social mobilization activities were carried out did not appear to determine better SIA performance. CONCLUSIONS: Social mobilization activities can improve the performance of mass vaccination campaigns. In the CORE Group areas, the number of mosque announcements and Bullawa Tollies carried out were important determinants of desired SIA outcomes. The CORE Group and SM Net should conduct sufficient numbers of these activities in support of each SIA. It is likely, however, that the quality of social mobilization activities (not studied here) is as or more important than the quantity of activities; quality measures of social mobilization activities should be investigated in the future as to how they determine vaccination performance.

Performance and determinants of routine immunization coverage within the context of intensive polio eradication activities in Uttar Pradesh, India: Social Mobilization Network (SM Net) and Core Group Polio Project (CGPP).

BACKGROUND: Studies that have looked at the effect of polio eradication efforts in India on routine immunization programs have provided mixed findings. One polio eradication project, funded by US Agency for International Development (USAID) and carried out by the CORE Group Polio Project (CGPP) in the state of Uttar Pradesh of India, has included the strengthening of routine immunization systems as a core part of its polio eradication strategy. This paper explores the performance of routine immunization services in the CGPP intervention areas concurrent with intensive polio eradication activities. The paper also explores determinants of routine immunization performance such as caretaker characteristics and CGPP activities to strengthen routine immunization services. METHODS: We conduct secondary data analysis of the latest project household immunization survey in 2011 and compare these findings to reports of past surveys in the CGPP program area and at the Uttar Pradesh state level (as measured by children's receipt of DPT vaccinations). This is done to judge if there is any evidence that routine immunization services are being disrupted. We also model characteristics of survey respondents and respondents' exposure to CGPP, communication activities against their children's receipt of key vaccinations in order to identify determinants of routine immunization coverage. RESULTS: Routine immunization coverage has increased between the first survey (2005 for state level estimates, 2008 for the CGPP program) and the latest (2011 for both state level and CGPP areas), as measured by children's receipt of DPT vaccination. This increase occurred concurrent with polio eradication efforts intensive enough to result in interruption of transmission. In addition, a mothers' exposure to specific communication materials, her religion and education were associated with whether or not her children receive one or more doses of DPT. CONCLUSIONS: A limitation of the analysis is the absence of a controlled comparison. It is possible routine immunization coverage would have increased even more in the absence of polio eradication efforts. At the same time, however, there is no evidence that routine immunization services were disrupted by polio eradication efforts. Targeted health communications are helpful in improving routine immunization performance. Strategies to address other determinants of routine immunization, such as religion and education, are also needed to maximize coverage.

Isolated medial patellofemoral reconstruction outcomes: A systematic review and meta-analysis.

BACKGROUND: Treatment of patellar instability remains up for debate, and a combination of tibial tubercle osteotomy and medial patellofemoral ligament reconstruction (MPFLr) of the medial patellofemoral ligament (MPFL) has become the mainstay treatment for recurrent lateral patellar dislocation. Due to limited small studies, there remains a variety of surgical techniques still being practiced. The use of MPFL reconstruction, in isolation, has demonstrated promise. PURPOSE: The purpose of this systematic review and meta-analysis is to investigate if isolated medial patellofemoral ligament reconstruction (iMPFLr) can safely and efficaciously restore knee stability and to present the patient demographics, surgical techniques, graft choices, clinical outcomes, and complications after iMPFLr for recurrent patellar dislocation (RPD). METHODS: A review of the current literature according to Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, yielded 299 abstracts. Twenty-seven articles met the inclusion/exclusion criteria accounting for 1200 patients. Data was pooled and analyzed focusing on patient demographics, graft type used, Kujala, International Knee Documentation Committee (IKDC), Lysholm, Tegner, and complications. RESULTS: Across all studies the weighted mean age was found to be an average of 24.5 years, BMI was 24.9 kg/m2, follow-up was 47.3 months, as 67% were female, TT-TG distance was 15.3 mm, and Caton Deschamps index 1.11. The pooled effect size difference of pre versus post assessment of Kujala was -2.8, IKDC was -4.5, Lysholm was -6.4, and Tegner was -0.74. The pooled complication rate was found to be 8% across all included studies. A subgroup analysis was also performed, specifically looking at how single bundle, double bundle, gracilis, semitendinosus and knee angle during fixation effect outcome data. CONCLUSION: This systematic review and meta-analysis demonstrates that isolated MPFL reconstruction is a safe and effective treatment for recurrent patellar dislocations. Given the efficacy of isolated MPFL reconstruction, future investigations should aim to uncover the exact TT-TG distance, trochlear dysplasia, and patella alta grade for selecting patients to undergo this procedure. Furthermore, more primary research needs to be conducted on this topic due to the overall lack of published data from randomized controlled studies and no broad standardization of outcome measurements. LEVEL OF EVIDENCE: (4) Systematic Review and Meta-Analysis.

Using a logic model to design and evaluate quality and patient safety improvement programs.

Quality improvement programs often pose unique project management challenges, including multi-faceted interventions that evolve over time and teams with few resources for data collection. Thus, it is difficult to report methods and results. We developed a program to reduce central line-associated bloodstream infections (CLABSIs) and improve safety culture in intensive care units (ICUs). As previously reported, we worked with 103 Michigan ICUs to implement this program, and they achieved a 66% reduction in the median CLABSI rate and sustained the reduction. This success prompted the spread of this program to Spain, England, Peru and across the USA. We developed a logical framework approach (LFA) to guide project management; to incorporate the cultural, clinical and capacity variations among countries; and to ensure early alignment of the project's design and evaluation. In this paper, we describe the use of the LFA to systematically design, implement and evaluate large-scale, multi-faceted, quality improvement programs.

Outcomes of polio eradication activities in Uttar Pradesh, India: the Social Mobilization Network (SM Net) and Core Group Polio Project (CGPP).

BACKGROUND: The primary strategy to interrupt transmission of wild poliovirus in India is to improve supplemental immunization activities and routine immunization coverage in priority districts with a focus on 107 high-risk blocks of western Uttar Pradesh and central Bihar. Villages or urban areas with a history of wild poliovirus transmission, or hard-to-reach or resistant populations are categorized as high-risk areas within blocks. The Social Mobilization Network (SM Net) was formed in Uttar Pradesh in 2003 to support polio eradication efforts through improved planning, implementation and monitoring of social mobilization activities in those high-risk areas. In this paper, we examine the vaccination outcomes in districts of SM Net where the CORE Group works. METHODS: We carried out a secondary data analysis of routine monitoring information collected by the SM Net and the Government of India. These data include information about vaccination outcomes in SM Net areas and non-SM Net areas within the districts where the CORE Group operates. Statistical analysis was used to compare, between SM Net and non-SM Net areas, vaccination outcomes considered sensitive to social mobilization efforts of the SM Net. We employed Generalized Estimating Equations (GEE) statistical method to account for Intra-cluster Correlation (ICC), and used 'Quasi-likelihood under the independence model criterion (QIC)' as the model selection method. RESULTS: Vaccination outcomes in SM Net areas were as high as or higher than in non-SM Net areas. There was considerable variation in vaccination outcomes between districts. CONCLUSIONS: While not conclusive, the results suggest that the social mobilization efforts of the SM Net and the CORE Group are helping to increase vaccination levels in high-risk areas of Uttar Pradesh. Vaccination outcomes in CORE Group areas were equal or higher than in non-CORE, non-SM Net areas. This occurred even though SM Net areas are those with more community resistance to polio vaccination and/or are have harder-to-reach populations than non-SM Net areas. Other likely explanations for the relatively good vaccination performance in SM Net areas are not apparent.
