ABSTRACT

BACKGROUND: Despite a glaring need and proven efficacy, prospective surgical registries are lacking in low- and middle-income countries. The objective of this study was to design and implement a comprehensive prospective perioperative registry in a low-income country. METHODS: This study was conducted at Hawassa University Comprehensive Specialized Hospital in Hawassa, Ethiopia. Design of the registry occurred from June 2021 to May 2022 and pilot implementation from May 2022 to May 2023. All patients undergoing elective or emergent general surgery were included. Following one year, operability and fidelity of the registry were analyzed by assessing capture rate, incidence of missing data, and accuracy. RESULTS: A total of 67 variables were included in the registry including demographics, preoperative, operative, post-operative, and 30-day data. Of 440 eligible patients, 226 (51.4%) were successfully captured. Overall incidence of missing data and accuracy was 5.4% and 90.2% respectively. Post pilot modifications enhanced capture rate to 70.5% and further optimized data collection processes. CONCLUSION: The establishment of a low-cost electronic prospective perioperative registry in a low-income country represents a significant step forward in enhancing surgical care in under-resourced settings. The initial success of this registry highlights the feasibility of such endeavors when strong partnerships and local context are at the center of implementation. Continuous efforts to refine this registry are ongoing, which will ultimately lead to enhanced surgical quality, research output, and expansion to other sites.

ABSTRACT

BACKGROUND: The rising burden of cancer significantly influences the global economy and healthcare systems. While local and contextual cancer research is crucial, it is often limited by the availability of funds. In South Asia, with 1.7 million new cancer cases and 1.1 million deaths due to cancer in 2020, understanding cancer research funding trends is pivotal. METHODS: We reviewed funded cancer studies conducted between January 1, 2003, and Dec 31, 2022, using ClinicalTrials.gov, International Cancer Research Partnership (ICRP) Database, NIH World RePORT, and WHO International Clinical Trials Registry Platform (ICTRP). We included funded studies related to all cancer types, conducted in South Asian countries, namely Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka. RESULTS: We identified 6561 funded cancer studies from South Asia between 2003 and 2022, increasing from 400 studies in 2003-2007 to 3909 studies in 2018-2022. India had the highest number of funded cancer studies, while Afghanistan, Bhutan, and the Maldives had minimal or no funded cancer research output. Interventional studies (67.3%) were the most common study type funded. The most common cancer sites funded were breast (17.8%), lung (9.9%), oropharyngeal (6.2%), and cervical (5.0%) cancers. On the WHO ICTRP, international funding agencies contributed to a majority of studies (57.5%), except in India where local funding agencies (58.2%) funded more studies. CONCLUSION: This study identified gaps in research funding distribution across cancer types and geographic areas in South Asia. This data can be used to optimize the distribution of cancer research funding in South Asia, fostering equitable advancement in cancer research.

ABSTRACT

Background: Perioperative data are essential to improve the safety of surgical care. However, surgical outcome research (SOR) from low- and middle-income countries (LMICs) is disproportionately sparse. We aimed to assess practices, barriers, facilitators, and perceptions influencing the collection and use of surgical outcome data (SOD) in LMICs. Methods: An internet-based survey was developed and disseminated to stakeholders involved in the care of surgical patients in LMICs. The Performance of Routine Information Systems Management framework was used to explore the frequency and relative importance of organizational, technical, and behavioral barriers. Associations were determined using χ 2 and ANOVA analyses. Results: Final analysis included 229 surgeons, anesthesia providers, nurses, and administrators from 36 separate LMICs. A total of 58.1% of individuals reported that their institution had experience with collection of SOD and 73% of these reported a positive impact on patient care. Mentorship and research training was available in <50% of respondent's institutions; however, those who had these were more likely to publish SOD (P = 0.02). Sixteen barriers met the threshold for significance of which the top 3 were the burden of clinical responsibility, research costs, and accuracy of medical documentation. The most frequently proposed solutions were the availability of an electronic data collection platform (95.3%), dedicated research personnel (93.2%), and access to research training (93.2%). Conclusions: There are several barriers and facilitators to collection of SOD that are common across LMICs. Most of these can be addressed through targeted interventions and are highlighted in this study. We provide a path towards advancing SOR in LMICs.

ABSTRACT

INTRODUCTION: Colon cancer (CC) is one of the most common cancers among South Asian Americans (SAAs). The objective of this study was to measure differences in risk-adjusted survival among SAAs with CC compared to non-Hispanic Whites (NHWs) using a representative national dataset from the United States. METHODS: A retrospective analysis of patients with CC in the National Cancer Database (2004-2020) was performed. Differences in presentation, management, median overall survival (OS), three-year survival, and five-year survival between SAAs and NHWs were compared. Kaplan-Meier analysis and multivariable Cox regression were used to assess differences in survival outcomes, adjusting for demographics, presentation, and treatments received. RESULTS: Data from 2873 SAA and 639,488 NHW patients with CC were analyzed. SAAs were younger at diagnosis (62.2 versus 69.5 y, P < 0.001), higher stage (stage III [29.0% versus 26.2%, P = 0.001] or Stage IV [21.4% versus 20.0%, P = 0.001]), and experienced delays to first treatment (SAA 5.9% versus 4.9%, P = 0.003). SAAs with CC had higher OS (median not achieved versus 68.1 mo for NHWs), three-year survival (76.3% versus 63.4%), and five-year survival (69.1% versus 52.9%). On multivariable Cox regression, SAAs with CC had a lower risk of death across all stages (hazard ratio: 0.64, P < 0.001). CONCLUSIONS: In this national study, SAA patients with CC presented earlier in life with more advanced disease, and a higher proportion experienced treatment delay compared to NHW patients. Despite these differences, SAAs had better adjusted OS than NHW, warranting further exploration of tumor biology and socioeconomic determinants of cancer outcomes in SAAs.

ABSTRACT

SUMMARY: Whereas 100% of Congressional legislators vote on healthcare policy, only a minority have a background in healthcare. A review of the participation of healthcare professionals (HCPs) in Congress, highlighting participation by surgeons, is critical to the future policy-making endeavors in healthcare. This article seeks to better understand the characteristics of HCPs that engage in advocacy and describe the trends in their representation in Congress, with commentary on participation by surgeons and its impact on current health advocacy efforts.A search of Congress.gov and the Biographical Directory of the United States Congress was performed to identify professional healthcare history for each Congressperson, followed by review of official campaign websites for health advocacy work. Statistical analysis was performed using IBM® SPSS® Statistics Software for changes in representation of healthcare professionals, physicians, and surgeons in Congress over time.While there has been increasing representation of HCPs in Congress in the last 25 years, surgeons have the lowest increase in Congressional membership. For healthcare reform to optimally address high costs, variable insurance coverage and reimbursement rates, and equal access to care, more physicians must make healthcare advocacy efforts an integral part of their careers. Incorporation of education in areas of healthcare advocacy and/or reform into undergraduate and graduate medical education curricula may help address deficiencies in knowledge of current healthcare-related events to further encourage involvement in healthcare legislation.

ABSTRACT

BACKGROUND: Long years of school/training have shown to be associated with infertility and pregnancy complications. Rates of infertility and pregnancy complications were compared among women in demanding professional careers to better understand career differences impacting family planning. METHODS: Inclusion criteria : English-speaking, childbearing professional women in surgery, medicine, law, and engineering. Exclusion criteria: men and women not in professional careers mentioned and non-childbearing women. Male-dominated fields identified to select non-medical female professionals. Top medical, law, and engineering schools' female faculty were surveyed from October 2022 to December 2022. Descriptive analysis and chi-squared tests were performed. RESULTS: 2302 surveys were distributed and 268 responses were obtained (11.6%): 121 non-surgeon physicians, 120 lawyers/other doctorate degree holders, and 27 other/unknown. Data analysis included prior study's surgeon data. The median age (IQR = 25%, 75%) of the surgeons was 40y (36,45), non-surgeon physicians 43y (37,50), and law/other doctorates 38y (35,46). Delayed childbearing was observed in 65.0% surgeons, 66.1% non-surgeon physicians, and 57.5% law/other doctorates (P < .001). Pregnancy loss <10wks was observed in 35.3% surgeons, 33.9% non-surgeon physicians, and 30.8% law/other doctorates (P < .001). Infertility testing was performed in 43.0% non-surgeon physicians and 34.2% law/other doctorates (P < .001). Assisted reproductive technology was utilized by 24.9% surgeons, 43.0% non-surgeon physicians, and 21.7% law/other doctorates (P < .001). DISCUSSION: Surgeons/physicians suffer more childbearing complications than other professional women.

ABSTRACT

BACKGROUND: While lower socioeconomic status has been shown to correlate with worse outcomes in cancer care, data correlating neighborhood-level metrics with outcomes are scarce. We aim to explore the association between neighborhood disadvantage and both short- and long-term postoperative outcomes in patients undergoing pancreatectomy for pancreatic ductal adenocarcinoma (PDAC). PATIENTS AND METHODS: We retrospectively analyzed 243 patients who underwent resection for PDAC at a single institution between 1 January 2010 and 15 September 2021. To measure neighborhood disadvantage, the cohort was divided into tertiles by Area Deprivation Index (ADI). Short-term outcomes of interest were minor complications, major complications, unplanned readmission within 30 days, prolonged hospitalization, and delayed gastric emptying (DGE). The long-term outcome of interest was overall survival. Logistic regression was used to test short-term outcomes; Cox proportional hazards models and Kaplan-Meier method were used for long-term outcomes. RESULTS: The median ADI of the cohort was 49 (IQR 32-64.5). On adjusted analysis, the high-ADI group demonstrated greater odds of suffering a major complication (odds ratio [OR], 2.78; 95% confidence interval [CI], 1.26-6.40; p = 0.01) and of an unplanned readmission (OR, 3.09; 95% CI, 1.16-9.28; p = 0.03) compared with the low-ADI group. There were no significant differences between groups in the odds of minor complications, prolonged hospitalization, or DGE (all p > 0.05). High ADI did not confer an increased hazard of death (p = 0.63). CONCLUSIONS: We found that worse neighborhood disadvantage is associated with a higher risk of major complication and unplanned readmission after pancreatectomy for PDAC.

ABSTRACT

Aneurysms are characterized by focal dilation of the blood vessel wall due to weakening. The involvement of two layers of the vessel wall is classified as a pseudoaneurysm while the involvement of all three layers is called a true aneurysm. Involvement of neoplastic lesions is rare, but the few reported cases have been associated with pulmonary artery pseudoaneurysms as opposed to true pulmonary artery aneurysms (PAAs). Our case of a true left PAA of a patient with metastatic sarcoma of the lung shows an association that has previously not been reported to the best of our knowledge.

ABSTRACT

Background: Current understanding of medical debt among various income ranges and insurance carriers is limited. We analyzed median household incomes, insurance carriers, and medical debt of plastic surgery patients at a major metropolitan children's hospital. Methods: A retrospective chart review for zip codes, insurance carriers, and account balances was conducted for 2018-2021. All patients were seen by members of the Division of Pediatric Plastic Surgery at Ann and Robert H. Lurie Children's Hospital of Chicago. Blue Cross was reported separately among other commercial insurance carriers by the hospital's business analytics department. Median household income by zip code was obtained. IBM SPSS Statistics was used to perform chi-squared tests to study the distribution of unpaid account balances by income ranges and insurance carriers. Results: Of the 6877 patients, 630 had unpaid account balances. Significant differences in unpaid account balances existed among twelve insurance classes (P < 0.001). There were significant differences among unpaid account balances when further examined by median household income ranges for Blue Cross (P < 0.001) and other commercial insurance carriers (P < 0.001). Conclusions: Although patients with insurance policies requiring higher out-of-pocket costs (ie, Blue Cross and other commercial insurance carriers) are generally characterized by higher household incomes, these patients were found to have higher unpaid account balances than patients with public insurance policies. This suggests that income alone is not predictive of unpaid medical debt and provides greater appreciation of lower income families who may make a more consistent effort in repaying their medical debt.

ABSTRACT

INTRODUCTION: With an incidence of 2-16%, radial nerve palsy is one of the common forms of nerve injuries globally. Radial nerve palsy causes debilitating effects including loss of elbow extension, wrist drop and loss of finger extension. Reparative surgical pathways range from primary repair and neurolysis, to nerve grafting, nerve transfers, and tendon transfers. Due to ease of performance and acceptability and reproducibility of outcomes, tendon transfers are considered the gold standard of radial nerve palsy repair. However, independent finger function cannot be achieved and as such may not give truly desirable results. In lower-middle income countries, the question of nerve transfer versus tendon transfer for patients who are keen to get back to work is key. While tendon transfer recovery is faster, the functional loss is often considered devastating for fine hand function due to loss of grip secondary to lack of wrist and finger extension. In this study, we present our experience of performing median nerve transfers for radial nerve palsy in Pakistan. METHODS: We performed a retrospective case-series of patients undergoing median to radial nerve transfer for radial nerve palsy over a period of 6 y, from 2012 to 2019. Patients with radial nerve palsy were diagnosed via electromyography and nerve conduction studies. The procedure involved coapting the branches of the flexor carpi radialis and flexor digitorum superficialis (long and ring finger) nerves to the posterior interosseous nerve and extensor carpi radialis brevis, respectively. Patients were assessed using the Medical Research Council scale for muscle strength of wrist, finger and thumb extension separately at 1 y time. Our results were then compared to results from similar nerve transfer studies. RESULTS: We operated on 10 right-hand dominant patients, eight males and two females with a median age of 33 y (6-63 y). four sustained injury to the right hand and six to the left. Causes of the injuries included road traffic accident (n = 3), firearm injury (n = 4), shrapnel (n = 1), iatrogenic injury (injection in deltoid region (n = 1) and fall (n = 1). Types of fracture included mid humerus fracture, fracture of the surgical neck of the humerus, and supracondylar fracture of the humerus. Median time to surgery since injury was 4 mo (1-8 mo). Independent wrist extension was M4+ in all patients and independent finger extension was M4+ in seven and M4-in two patients. However, a patient who presented late at 8 mo had poorer finger outcomes with extension at M2-. All patients had independent movement of fingers. CONCLUSIONS: Nerve transfer is a reliable method of post traumatic nerve repair and reinnervation, particularly in lower-middle income countries, even in cases where the nerve damage is severe and extensive and up to 6 mo may have elapsed between injury and presentation. Timely median to radial nerve transfer is a highly recommended option for radial nerve palsy, with regular follow-ups and physical therapy added to ensure positive outcomes.

ABSTRACT

INTRODUCTION: Systematic collection and analysis of surgical outcomes data is a cornerstone of surgical quality improvement. Unfortunately, there remains a dearth of surgical outcomes data from low- and middle-income countries (LMICs). To improve surgical outcomes in LMICs, it is essential to have the ability to collect, analyze, and report risk-adjusted postoperative morbidity and mortality data. This study aimed to review the barriers and challenges to developing perioperative registries in LMIC settings. METHODS: We conducted a scoping review of all published literature on barriers to conducting surgical outcomes research in LMICs using PubMed, Embase, Scopus, and GoogleScholar. Keywords included 'surgery', 'outcomes research', 'registries', 'barriers', and synonymous Medical Subject Headings derivatives. Articles found were subsequently reference-mined. All relevant original research and reviews published between 2000 and 2021 were included. The performance of routine information system management framework was used to organize identified barriers into technical, organizational, or behavioral factors. RESULTS: Twelve articles were identified in our search. Ten articles focused specifically on the creation, success, and obstacles faced during the implementation of trauma registries. Technical factors reported by 50% of the articles included limited access to a digital platform for data entry, lack of standardization of forms, and complexity of said forms. 91.7% articles mentioned organizational factors, including the availability of resources, financial constraints, human resources, and lack of consistent electricity. Behavioral factors highlighted by 66.6% of the studies included lack of team commitment, job constraints, and clinical burden, which contributed to poor compliance and dwindling data collection over time. CONCLUSIONS: There is a paucity of published literature on barriers to developing and maintaining perioperative registries in LMICs. There is an immediate need to study and understand barriers and facilitators to the continuous collection of surgical outcomes in LMICs.

ABSTRACT

Growth of skin in response to stretch is the basis for tissue expansion (TE), a procedure to gain new skin area for reconstruction of large defects. Unfortunately, complications and suboptimal outcomes persist because TE is planned and executed based on physician's experience and trial and error instead of predictive quantitative tools. Recently, we calibrated computational models of TE to a porcine animal model of tissue expansion, showing that skin growth is proportional to stretch with a characteristic time constant. Here, we use our calibrated model to predict skin growth in cases of pediatric reconstruction. Available from the clinical setting are the expander shapes and inflation protocols. We create low fidelity semi-analytical models and finite element models for each of the clinical cases. To account for uncertainty in the response expected from translating the models from the animal experiments to the pediatric population, we create multifidelity Gaussian process surrogates to propagate uncertainty in the mechanical properties and the biological response. Predictions with uncertainty for the clinical setting are essential to bridge our knowledge from the large animal experiments to guide and improve the treatment of pediatric patients. Future calibration of the model with patient-specific data-such as estimation of mechanical properties and area growth in the operating room-will change the standard for planning and execution of TE protocols.

ABSTRACT

Introduction There is currently no consensus as to the comparative complication profiles of mini-plate (MP) and reconstruction bar (RB) osseous fixation in fibula flap mandibular reconstruction. The aim of this study is to compare complication rates associated with the use of MP versus RB fixation for vascularized fibula free flap (FFF) reconstruction of oncologic mandibular defects in an effort to better guide hardware utilization and pre-operative virtual surgical planning methods. Methods A systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, EMBASE, and Cochrane Library databases were queried to identify studies related to FFF-based mandibular reconstruction with either MP or RB fixation. Primary endpoints of interest were plate complications, wound infection, mal- or non-union, and total flap loss. Complication rates were calculated as weighted proportions and compared via Fisher's exact testing. Results Sixteen studies met inclusion criteria, which examined 1,513 patients. Only three studies directly compared MP fixation with RB fixation. MP fixation was used in 828 (54.7%) cases and RB fixation in 685 (45.3%) cases. MP fixation demonstrated greater rates of plate-related complications (32.5% versus 18.8%, p < 0.01, respectively), fistula formation (15.8% versus 4.7%, p = 0.04), total flap loss (9.4% versus 4.7%, p = 0.02), partial flap loss (20.6% versus 6.1%, p < 0.01), and re-operation for vascular compromise (13.3% versus 4.0%, p < 0.01). Rates of infection, mal-union/non-union, and wound dehiscence were similar across both groups. Conclusion Our results suggest that MP use may be associated with higher rates of plate-related complications. Though limited by outcome reporting heterogeneity, this review can serve as a template for future investigations evaluating the safety profiles of MP and RB fixation in head and neck surgery.

ABSTRACT

Sympathetic ophthalmia (SO) is a rare, severe condition that typically presents as bilateral diffuse granulomatous uveitis secondary to trauma in one eye. The variability of symptoms requires that diagnosis depends heavily on the correlation of these symptoms with relevant imaging. Visualisation of characteristic nodules seen between the Bruchs membrane and the retinal pigment epithelium, and the presence of Dalén Fuchs nodules, can be diagnostic when coupled with the clinical findings. This report discusses the use of spectral domain optical coherence tomography (OCT) to indicate the presence of Dalén Fuchs nodules, which have previously not been identified on OCT in a confirmed case of SO.

ABSTRACT

INTRODUCTION: The need for precision in craniomaxillofacial surgery has necessitated the evolution of new technology to improve patient outcomes and subsequently augment the road to recovery. Surgical planning has variables that may influence outcomes, including the image quality, image acquisition and image processing. Our review focuses on the advancement of three dimensional (3D) printing to create patient-specific constructs and therefore aims to study the current trends in the implementation of 3-D printing in craniofacial surgeries, including preferred 3-D printing techniques and materials, computer-aided design and manufacturing techniques, and outcomes as measured by recent studies. METHODS: The authors conducted a systematic review following PRISMA guidelines to query PubMed, Embase, Cochrane library and ProQuest electronic databases. Mesh combinations and synonyms of "3Dprinting", "3Dprinted", "Craniofacial" were used. The authors included all original human studies that focused on the surgical implementation of 3D-printed implants for craniofacial defects. RESULTS: After screening 1253 studies, the authors included 49 articles consisting of a total of 745 subjects for qualitative analysis. Titanium (n = 13) and polycaprolactone (n = 6) were the most common 3D printed materials studied while Color Jet Printing (n = 12) and Stereolithography (n = 11) were the most common techniques. All studies that compared implants acquired by 3D printing with those acquired by conventional approaches showed a significantly better prognosis, and reductions in operative time, length of stay, and immediate complications. CONCLUSIONS: The use of patient-specific alternative materials, planning software and 3-D printing techniques shows satisfactory results in craniofacial reconstruction. Future studies should include standard levels of objective measurements to make better comparisons.

ABSTRACT

Deep learning (DL) is a relatively newer subdomain of machine learning (ML) with incredible potential for certain applications in the medical field. Given recent advances in its use in neuro-oncology, its role in diagnosing, prognosticating, and managing the care of cancer patients has been the subject of many research studies. The gamut of studies has shown that the landscape of algorithmic methods is constantly improving with each iteration from its inception. With the increase in the availability of high-quality data, more training sets will allow for higher fidelity models. However, logistical and ethical concerns over a prospective trial comparing prognostic abilities of DL and physicians severely limit the ability of this technology to be widely adopted. One of the medical tenets is judgment, a facet of medical decision making in DL that is often missing because of its inherent nature as a "black box." A natural distrust for newer technology, combined with a lack of autonomy that is normally expected in our current medical practices, is just one of several important limitations in implementation. In our review, we will first define and outline the different types of artificial intelligence (AI) as well as the role of AI in the current advances of clinical medicine. We briefly highlight several of the salient studies using different methods of DL in the realm of neuroradiology and summarize the key findings and challenges faced when using this nascent technology, particularly ethical challenges that could be faced by users of DL.

ABSTRACT

INTRODUCTION: Partial tongue reconstruction requires a thin pliable flap to restore volume and mobility. The lateral arm flap is well suited to this as it is a thin fasciocutaneous flap that has consistent vascular anatomy, reliable perfusion, short harvest time and low donor site morbidity. The authors report our experience with use of this flap for reconstruction of hemi-glossectomy defects. METHODS: This is a retrospective cohort of patients who underwent reconstruction of hemi-glossectomy and floor of mouth defects with a lateral arm flap, at Aga Khan University Hospital, Karachi (Pakistan) from November 2016 to January 2020. Flaps were harvested from the nondominant upper extremity. Data were collected for patient demographics, size of defect, size of flap, recipient vessels, postoperative complications and functional outcome. RESULTS: Over a 3-year period, 8 hemi-tongue and extended hemi-tongue, and floor of mouth reconstructions were performed with a lateral arm fasciocutaneous flap. A standard lateral arm flap was harvested in 3 patients and an extended lateral arm flap in 5 patients. Mean flap size was 65.75 cm2 (48-76 cm2). The recipient artery in all cases was the superior thyroid artery. The recipient veins were the common facial vein in 1 patient, the internal jugular in 3 patients, the external jugular in 1 patient and both external and internal jugular in 3 patients. Donor sites were closed primarily. There were no total or partial flap losses. All patients were able to resume an oral diet (unrestricted in 1, soft in 4, pureed in 2 patients). Postoperative speech was intelligible to patients' family in 4 patients and to strangers in 3 patients. One patient succumbed to progressive disease in the early postoperative period. Orocutaneous fistulas developed in 3 patients, all of which healed with nonoperative management. CONCLUSIONS: The lateral arm fasciocutaneous flap is well suited for reconstruction of hemiglossectomy and floor of mouth defect. It has the advantages of straightforward harvest, thin and pliable soft tissue, and low donor site morbidity.
