Background: Prior studies have reported higher rates of periprosthetic fracture, superficial infection, and neurologic deficit with the direct anterior approach (DAA), and higher rates of dislocation with the posterior approach (PA) for total hip arthroplasty (THA). Despite these differences, the overall clinical burden of complications between approaches remains unclear. The purpose of this study was to compare the profiles, severity, impact, and resolution of 5 clinically important complications between DAA and PA THA. Methods: A retrospective review was conducted of 11,783 consecutive primary THAs performed between 2010 and 2021 across 3 centers within a single healthcare system, using either the DAA (n = 4,451) or the PA (n = 7,332). Complications assessed included dislocation, infection, periprosthetic fracture (PPFx), aseptic loosening, and neurologic deficit. Severity was graded using the Clavien-Dindo classification (I = minor, V = death). Impact was defined by reoperation burden, and outcomes were categorized as resolved or persistent. Kaplan-Meier survivorship and propensity-weighted Cox proportional hazards models were used to compare complication risk. Results: The overall 1-year risk of surgical complications did not differ between DAA and PA (hazard ratio [HR], 0.89; 95% confidence interval [CI], 0.75-1.06; p = 0.208). Dislocation occurred more frequently with PA THA than DAA THA (1.9% vs. 0.4%; HR, 5.20; 95% CI, 3.04-8.90; p < 0.001). Superficial infections were more frequent with the DAA (1.6% vs. 0.8%; HR, 2.43; 95% CI, 1.68-3.53; p < 0.001). The risk of deep infection, PPFx, aseptic loosening, and neurologic deficit did not differ significantly between approaches. Among patients with complications, the proportion classified as severe (Clavien-Dindo III–V) was similar, and adjusted analyses showed no difference in the odds of severe complications (adjusted odds ratio 1.34 for PA vs DAA; 95% CI, 0.95-1.91; p = 0.099). Complication impact and resolution were likewise comparable. Conclusion: Although the profile of complications differed between DAA and PA THA, the severity, early clinical impact, and resolution of complications appeared similar. Notably, DAA was associated with a lower risk of dislocation and a higher risk of superficial infection compared with PA THA. Level of Evidence: Level III , Retrospective Comparative Study.

PURPOSE Oncology pharmacists (OPs) play a crucial role in cancer care, treatment, survivorship, and multidisciplinary teams (MDTs). OPs have specialized training in designing, administering, monitoring, and modifying oncology chemotherapy; managing adverse events; and evaluating clinical trials and investigational drugs. Yet, the state of OP has remained largely unknown in the clinical oncology workforce of the West African region. Therefore, this study aimed to understand who reconstitutes chemotherapy and to explain the OP educational and practice needs, challenges, and solutions in Nigeria. MATERIALS AND METHODS Using a concurrent embedded mixed method design, 35 OPs completed a questionnaire, and 12 others responded to a semistructured interview. The data were then subjected to inductive thematic and descriptive analyses. RESULTS The findings showed that 54% of the OPs were responsible for chemotherapy reconstitution, and only 60% of the oncology centers had a biosafety cabinet. 91% of OPs were practicing; however, only 54% were trained in OP, and none of the OPs were board-certified. Most of the OPs spent time weekly on reconstitution, administrative duties, teaching, and training; only 3% spent on oncology clinical trials and conferences and 8% on noninterventional research. We identified four themes: (1) Some OPs are not reconstituting chemotherapy: A Call for MDT, (2) For OP, No Training is Enough, (3) Board Certification will give OPs Recognition, and (4) Introduction of OP Course in Universities. CONCLUSION To improve patient treatment outcomes, training on chemotherapy reconstitution should be prioritized, integration of OPs into MDTs, and the safe handling of chemotherapy in centers should be mandated in the region. The West African Postgraduate College of Pharmacists should be supported in expanding its curriculum and introducing OP fellowships.

AbstractMorbidity and mortality rates in patients with autosomal recessive, congenital generalized lipodystrophy type 4 (CGL4), an ultra‐rare disorder, remain unclear. We report on 30 females and 16 males from 10 countries with biallelic null variants in CAVIN1 gene (mean age, 12 years; range, 2 months to 41 years). Hypertriglyceridemia was seen in 79% (34/43), hepatic steatosis in 82% (27/33) but diabetes mellitus in only 21% (8/44). Myopathy with elevated serum creatine kinase levels (346–3325 IU/L) affected all of them (38/38). 39% had scoliosis (10/26) and 57% had atlantoaxial instability (8/14). Cardiac arrhythmias were detected in 57% (20/35) and 46% had ventricular tachycardia (16/35). Congenital pyloric stenosis was diagnosed in 39% (18/46), 9 had esophageal dysmotility and 19 had intestinal dysmotility. Four patients suffered from intestinal perforations. Seven patients died at mean age of 17 years (range: 2 months to 39 years). The cause of death in four patients was cardiac arrhythmia and sudden death, while others died of prematurity, gastrointestinal perforation, and infected foot ulcers leading to sepsis. Our study highlights high prevalence of myopathy, metabolic abnormalities, cardiac, and gastrointestinal problems in patients with CGL4. CGL4 patients are at high risk of early death mainly caused by cardiac arrhythmias.

Background: Vertebral body tethering and other non-fusion techniques for the treatment of pediatric idiopathic scoliosis are increasing in popularity. There is limited physician consensus on this topic as the result of a paucity of published data regarding which patients most benefit from non-fusion strategies. Thus, much of the decision-making is left to patients and parents, who must select a treatment based on their goals and values and the information available from health-care providers, the internet, and social media. We sought to understand patient and family preferences regarding the attributes of fusion versus non-fusion surgery that drive these choices. Methods: Patients and families were recruited from 7 pediatric spine centers and were asked to complete a survey-based choice experiment that had been jointly developed with the U.S. Food and Drug Administration (FDA) to evaluate patient preferences. Choices between experimentally designed alternatives were analyzed to estimate the relative importance of outcomes and requirements associated with the choice options (attributes). The attributes included appearance, confidence in the planned correction, spinal motion, device failure, reoperation, and recovery period. The inclusion criteria were (1) an age of 10 to 21 years and (2) a diagnosis of adolescent idiopathic scoliosis in patients who were considering, or who had already undergone, treatment with fusion or non-fusion surgery. Preference weights were estimated from the expected changes in choice given changes in the attributes. Results: A total of 344 respondents (124 patients, 92 parents, and 128 parent/patient dyads) completed the survey. One hundred and seventy-three patients were enrolled prior to surgery, and 171 were enrolled after surgery. Appearance and motion were found to be the most important drivers of choice. For the entire cohort, fusion was preferred over non-fusion. For patients who were considering surgery, the most important attributes were preservation of spinal motion and appearance. Conclusions: Patients and families seeking treatment for idiopathic scoliosis value appearance and preservation of spinal motion and, to a lesser extent, reoperation rates when considering fusion versus non-fusion surgery.

Abstract BackgroundNigeria has the highest cancer burden in Africa with 124,815 cancer cases and 78,899 cancer deaths in 2020. The limited number of oncology specialists, inaccessibility of essential cancer medicines like chemotherapies, and suboptimal delivery of cancer care lead to poor treatment outcomes. Oncology pharmacy (OP) practitioners are critical oncology professionals in the multidisciplinary team (MDT) for cancer treatment globally. In Nigeria, there is a limited number of OP practitioners providing services like reconstitution of chemotherapy, clinical research, safe use of biosafety cabinets, and monitoring of adverse drug reactions. Although the interest in oncology pharmacy is increasing, the educational needs, available skill sets, and directed training in oncology pharmacy across the nation are unknown. In this study, we examined the educational needs of OP practitioners and worked with the West African College of Pharmacy West African Postgraduate College of Pharmacists (WAPCP), Oncology Pharmacy Practitioners Association of Nigeria (OPPAN), and the International Society of Oncology Pharmacy Practitioners to upgrade the oncology pharmacy practice in Nigeria. MethodA cross-sectional study with a semi-structured questionnaire was done in 2021 with 39 pharmacists working in oncology centers across Nigeria. General descriptive statistics and qualitative analysis was performed. ResultsThere is no board-certified oncology pharmacist in Nigeria. More than 50% of the general pharmacists working in oncology centers are responsible for chemotherapy reconstitution. Understanding chemotherapy reconstitution (automation of chemotherapeutic mixing, use of radiopharmaceuticals, etc), use of biosafety cabinets, knowledge of pharmacology, designing treatment protocols, data management, immunotherapy delivery, and oncology clinical trials were some of the most significant educational needs of the OP practitioners in Nigeria. OP practitioners are lacking in most cancer centers and MDTs. ConclusionThere is an urgent need for a specialty postgraduate training programme in oncology pharmacy in Nigeria. This would help increase oncology clinical trials, improve delivery of cancer medicines, quality of care, and management of toxicities. The West African Postgraduate College of Pharmacists and OPPAN need appropriate training resources to develop an oncology pharmacy curriculum, promote the specialty and collaborate with global institutions for board certifications.

Background: Physician-led smoking cessation services are suboptimal in Nigeria. Objectives: This study evaluated a text messaging intervention designed to increase the knowledge and practices of physicians in Nigeria to help smokers quit. Methods: Using a pre-post study design, all physicians ( N = 946) in 3 tertiary care hospitals located in 3 geopolitical zones in Nigeria were sent 2–3 text messages weekly over a 13-week period to create awareness and improve cessation practices using the “Ask, Advise and Refer” (AAR) model. The primary outcomes were the awareness of AAR and the proportion of physicians who offered each of the components of the brief intervention (AAR) to at least half of eligible patients. Secondary outcomes included the attitudes and self-reported effects of the messages on motivation to offer AAR to patients who smoke. Results: Of the 946 eligible respondents, only 165 responded to both the before and after intervention surveys (17.4% participation rate). Participants were more likely to indicate awareness of the AAR approach after the intervention (60%) than before (21.2%). Overall, physicians’ practice of each component of the AAR changed significantly after the intervention ( P < .001; McNemar test). Of the participants, 71.5% reported reading the messages most/all of the time and 84.8% reported that the frequency of the messages was just adequate. Conclusions: A brief and low-cost text messaging intervention to physicians increased the awareness and practice of AAR in those who participated in the study. However, the relatively low participation rate highlights the importance of new research to improve and expand text messaging as an intervention among physicians to help them foster tobacco treatment among their patients.
