Published: July 2024

Background: Proximal row carpectomy (PRC) is a mainstay of wrist arthritis treatment; however, it is traditionally contraindicated in patients with an affected capitate. The use of soft tissue interposition grafts to resurface the radiocapitate articulation has been previously described to allow for PRC in these patients. In the current study, we reviewed our outcomes using knee meniscus allograft interposition to resurface the radiocapitate articulation in patients who would have otherwise been contraindicated for PRC. Methods: A retrospective study of patients who underwent PRC with or without meniscus interposition arthroplasty was performed from 2011 to 2022. Patient demographics (age, sex, occupation, hand dominance, etc) were collected. Improvement in pain was the primary outcome. Wrist range of motion and reconstructive failure requiring fusion were the secondary outcomes. Results: We identified a total of 83 patients and 43 met the inclusion criteria. Fifteen patients (35%) underwent PRC with meniscus interposition arthroplasty, and 28 patients (65%) underwent PRC alone. Patients with and without meniscus interposition arthroplasty had documented improvement in pain postoperatively (93% vs 95%, P > .05) at a median follow-up time of 11 (range, 3-38 months) and 9 months (range, 3-64 months), respectively. Postoperative wrist range of motion (flexion: +9 vs −4, P > .05, extension: +12 vs −4, P = .10) trended toward increase in patients undergoing meniscus interposition arthroplasty compared with PRC alone. Conclusions: Our short- to mid-term outcomes in patients with end-stage wrist arthritis affecting the capitate who undergo PRC and meniscus interposition arthroplasty are comparable with those receiving PRC alone.

Published: July 2024

Background: We sought to improve the current understanding of how climate change impacts women’s reproductive health in sub-Saharan Africa. Objectives: We investigated the relationship between maternal heat exposure and miscarriage (pregnancy ending before 20 weeks gestation) in a South African setting. Design: Population-based cohort study. Methods: Our study involved data for pregnancies collected via a health and demographic surveillance system in rural KwaZulu-Natal, South Africa between 2012 and 2016. Data from the South African Weather Service were used to compute maternal exposure to heat during the following time windows for each pregnancy: during the month preceding conception (T1) and during the week preceding the study outcome (either a miscarriage or no miscarriage, T2). Heat exposure was operationalized as a continuous variable and defined as the number of days that a mother was exposed to a mean daily temperature of > 26.6°C (A “hot day,” equivalent to a mean daily temperature of > 80°F) during T1 or T2. Binary logistic regression was used to investigate the relationship between maternal heat exposure and miscarriage. Results: A total of 105/3477 pregnancies included in our analysis ended in miscarriage (3.0%). Each additional hot day during T1 was associated with a 26% higher odds of miscarriage (odds ratio: 1.26; 95% confidence interval: 1.15–1.38). No significant associations were observed between maternal heat exposure during T2 and the odds of miscarriage (odds ratio: 0.94, 95% confidence interval: 0.73–1.20). The relationship between maternal heat exposure during T1 and the odds of miscarriage was J-shaped. Conclusion: There is a clear relationship between maternal heat exposure during the month preceding conception and miscarriage in our sub-Saharan African setting. Given the lack of feasible strategies to reduce pregnancy loss associated with prevailing high temperatures in sub-Saharan Africa, progressive climate change will likely exacerbate existing challenges for women’s reproductive health in this region.
Cost of mate choice: Changing patterns of global age disparity in marriage and their consequences to women’s health including maternal mortality and menopause
Authors: Pru Mindy , Brown C Michelle , Singh Rama S 
Published: July 2024

Background: Consistent across cultures and throughout time is the male preference for younger females. Given its prevalence, the mate choice theory proposes that age–disparate relationships may have contributed to the evolution of maternal mortality and menopause. Objectives: The objective is to document evidence for age disparity in marriage from past and present populations and evaluate their relevance to maternal mortality and menopause. Design: Cross-sectional data were collected from various regions and time points, ranging from the Roman era to the current decade. Methods: To analyze both the age disparity in marriage and age at marriage, data were collected from Ancestry.ca for Quebec, Massachusetts, India, South Africa, and England and Wales. Additional data were taken from the United Nations as a more recent and comprehensive source. To analyze the relationships between age disparity in marriage and different social factors, data on gross domestic product, maternal mortality rates, fertility, primary school enrollment, child marriage rates, and percentage of women in the total labor force were collected from the World Health Organization, World Bank, and United Nations International Children’s Emergency Fund. Results: The results showed that males were significantly older than females at first marriage in all populations and time frames sampled, supporting the assumption underlying the mate choice theory. Maternal mortality rates were strongly associated with age–disparate relationships, increasing by 275 per 100,000 live births for each additional year in the age disparity. Conclusion: The results from this study provide support for the assumption underlying the mate choice theory of maternal mortality and menopause.

Published: July 2024

Background: Abdominal pain due to menses (primary dysmenorrhea) is an extremely pervasive and debilitating symptom affecting up to 90% of menstruating individuals. Objective: The objective of this randomized control trial was to investigate the effect of a commercial transcutaneous electrical nerve stimulation unit, Therabody PowerDot® (Therabody Inc., Los Angeles) on dysmenorrhea compared with non-steroidal anti-inflammatory drug use. Design: This was a randomized cross-over study. Methods: A total of 47 participants agreed to participate in the study, with 34 completing it. Participants completed treatments across three consecutive menstrual cycles in randomized order: single-unit transcutaneous electrical nerve stimulation (Uno), dual unit transcutaneous electrical nerve stimulation (Duo), and non-steroidal anti-inflammatory drug use (Control). Upon onset of dysmenorrhea, participants applied transcutaneous electrical nerve stimulation to their abdomen for a minimum of 30 min. Control participants were instructed to take non-steroidal anti-inflammatory drugs as needed. Surveys were used to record pain before and after treatment. We hypothesized that the PowerDot would decrease self-reported pain scores, and decrease non-steroidal anti-inflammatory drug consumption during menses. Results: Participants experienced a statistically and clinically significant reduction in pain during the Control (−3.52 ± 1.9), Uno (−2.10 ± 1.6), and Duo (−2.19 ± 1.7) cycles ( p < 0.001). The doses of non-steroidal anti-inflammatory drugs consumed during the Control cycle (3.5 ± 2.6), was significantly different as compared with that of Uno (1.5 ± 3.0), or Duo (1.1 ± 2.6) ( p = 0.004). Conclusions: Use of a commercial transcutaneous electrical nerve stimulation unit results in significant decrease in pain. Although not as robust as the relief in pain induced by non-steroidal anti-inflammatory drugs, the adverse events of transcutaneous electrical nerve stimulation are minimal in comparison. Therefore, transcutaneous electrical nerve stimulation appears to be a viable alternative to pain relief from dysmenorrhea. Clinical Trial Registration: NCT05178589

Published: July 2024

Introduction Studies have suggested a strong association between depression and poor outcomes following various orthopaedic surgeries. However, depression’s impact on complications following open reduction/internal fixation (ORIF) of trimalleolar fractures has not been elucidated. Therefore, this study aimed to determine whether depression is associated with higher rates of readmissions and medical complications following ORIF of trimalleolar fractures. Methods A database query from January, 2020, through March, 2021, identifying adults who underwent trimalleolar ORIF generated 50 154 patients. Those with depression were matched 1:1 to controls without depression by age, sex, chronic obstructive pulmonary disease, anxiety, and other prominent comorbidities. Primary endpoints compared 90-day all-cause readmissions and medical complications. Odds ratios (ORs) of the effect of depression on readmissions and medical complications were calculated. Results Patients with depression who underwent ORIF of trimalleolar fractures had significantly higher odds of being readmitted within 90 days of the initial procedure (OR: 1.37; P < .0001). Ninety-day odds of developing medical complications were significantly higher (OR: 4.61; P < .0001) in patients with depression compared with patients within the control group. Conclusion Patients with depression undergoing trimalleolar ORIF face an increased risk of readmission and multiple postoperative complications. Orthopaedic surgeons should factor depression into their preoperative evaluation, given the already high burden of complications following ORIF of trimalleolar fractures.

Published: July 2024

Case series summary Two cats, aged 13.5 and 14 years, presented with duodenal masses ultimately diagnosed as Brunner’s gland (BG) adenomas. In the first cat, the lesion was a firm, pale tan, proximal duodenal polyp adjacent to the major duodenal papilla that was composed histologically of a well demarcated, expansile mass of well-differentiated BGs separated by fibrovascular septa and few adipocytes. This patient was euthanized for otitis-related vestibular signs, and the clinical significance of the duodenal polyp is unknown. The second cat presented with a 6-month history of vomiting. This cat had a mural duodenal mass in the region of the major duodenal papilla of approximately 2 cm, which was histologically composed of a dense population of variably ectatic BGs expanding the submucosa and lamina propria. This patient’s mass was non-resectable, but the vomiting resolved after palliative gastroenterostomy loop surgery to allow ingesta to flow past the mass. The patient survived 35 months after the procedure. Relevance and novel information BG adenoma is a rare, typically benign tumor in humans with non-specific clinical manifestations and no clear etiopathogenesis. This lesion, and the related condition BG hyperplasia, has been documented rarely in animals (one dog, two horses, and in mice and rats). This is the first description of the lesion in the cat. The comparative pathology, differential diagnoses and possible significance of these lesions are discussed.
The Differential Effect of Internal and External Remittances on Labor Participation and Employment Choices in Pakistan

Published: July 2024

This study scrutinizes the effect of external and internal remittances on the outcomes of the labor market of Pakistan. The study uses data from PSLM – HIES 2018-2019. The labor participation analysis used the IV Probit model, while the labor supply analysis utilized the IV technique. The Multinomial Logit model with endogenous covariates is employed for the employment choice. The results reveal that an individual from a remittance-receiving household is less likely to participate in labor vis-à-vis an individual from a non-receiving household. The external and internal remittance inflow increases the labor supply for the labor-participating individual. In addition, more external remittances increase the likelihood of participation in self-employment than wage employment, which supports the positive effect of remittance inflow on labor supply. The higher internal remittances are associated with an increase in the likelihood of participation in farming. In short, our analysis supports the fact that the effect of external remittance is more pronounced on labor market outcomes than internal remittances. The study’s findings assist the labor economist in observing the obstacles in the labor force participation and policymaker to understand the entrepreneurial level and economic activities in the remittance-receiving households to turn the effect of remittance into a job creator.

Published: July 2024

Background: Total ankle arthroplasty (TAA) has primarily been performed in the inpatient setting. However, with the advent of fast-tracked joint arthroplasty protocols, TAA has slowly been shifting to the outpatient setting. Therefore, this systematic review aims to evaluate outcomes of outpatient TAA and compare them to inpatient TAA. Methods: A literature search was performed on October 23, 2023, in the PubMed, Embase, and CENTRAL databases using the PRISMA guidelines. Studies were included if they reported on outcomes of outpatient TAA or compared outcomes between outpatient and inpatient TAA. Pooled odds ratios (ORs) and mean differences were calculated using a random effects model. Quality assessment was performed using the MINORS criteria. Results: 12 studies were included, with 4 outpatient-only and 8 outpatient-inpatient comparative studies. Patients in the outpatient group were relatively younger, had a lower body mass index, and had fewer comorbidities relative to the inpatient group. For outpatient vs inpatient TAA, the pooled complication rate was 2.6% vs 3.6%, readmission rate was 2.5% vs 4%, and reoperation rate was 3.6% vs 5.5%. We found significantly lower odds of complications (OR = 0.47, CI: 0.26-0.85; P = .01), readmissions (OR = 0.63, CI: 0.54-0.74; P < .00001), and reoperations (OR = 0.66, CI: 0.46-0.95; P = .03) in the outpatient vs inpatient group. Conclusion: Although this analysis is limited by the dominance of data included from a single study, we found that outpatient TAA was generally performed on lower-risk patients and was associated with lower rates of complications, readmissions, and reoperations compared with inpatient TAA.
The Prisoner’s Dilemma game as a tool to investigate cooperation and undergraduate education in evolution
Authors: Russell James E. , Xu Xin 
Published: July 2024

AbstractEvolutionary theory is based on the conflict that arises when certain heritable variants out-compete others. Given this foundational conflict, a central question for evolutionary biologists concerns the presence of cooperation found throughout all levels of biological organization; from biochemical pathways to complex animal societies. Human behavior is often distinguished from other animal behavior by the presence of acts of cooperative behavior called altruism. Altruism is a cooperative act that penalizes the actor for actions that benefit the recipient. Any other form of cooperation, one that does not penalize the actor, is formally not considered altruistic. How can costly altruistic behavior evolve? This question was the basis for development of a web application tool incorporating a game theory model to investigate conditions affecting cooperative behavior. The game theory model described as Prisoner’s Dilemma incorporates acts of cooperation and non-cooperation (defection). Computer simulations of Prisoner’s Dilemma were developed and online applications were administered for five semesters at Georgia Gwinnett College, using two simulation environments referred to as Random and Non-random. Data collected from simulation runs were used to evaluate the effect of environment on student cooperative behavior and actively engage students in concepts associated with the evolution of cooperation and game theory. Results from student game play suggest group simulation environment played a significant role in the likelihood of observing cooperative behavior. Educational content and attitudinal surveys suggested that PD game play in the undergraduate evolution class at Georgia Gwinnett College improved student knowledge and self-confidence.

Published: July 2024

Abstract
Background and purpose
Cerebrovascular events during thrombolysis in cardiac arrest (CA) caused by pulmonary embolism (PE) is a life-threatening condition. However, the balance between cerebrovascular events and thrombolytic therapy in PE-induced CA remains a great challenge.

Methods
In this study, we reported three unique cases regarding main concerns surrounding cerebrovascular events in thrombolytic therapy in PE-induced CA.

Results
The patient in the case 1 treated with thrombolysis during CPR and finally discharged neurologically intact. The patient in the case 2 received delayed thrombolysis and died eventually. The patient in the case 3 was contraindicated to thrombolysis due to the complication of subarachioid hemorrahage and died within days.

Conclusions
Our case series highlights three proposed approaches to consider before administering thrombolysis as a treatment option in PE-induced CA patients: (1) prolonging the resuscitation, (2) administering thrombolysis promptly, and (3) ruling out cerebrovascular events.

Published: July 2024

Abstract
Background
Genetic diagnostics support the diagnosis of hereditary arrhythmogenic diseases, but variants of uncertain significance (VUS) complicate matters, emphasising the need for regular reassessment. Our study aims to reanalyse rare variants in different genes in order to decrease VUS diagnoses and thus improve risk stratification and personalized treatment for patients with arrhythmogenic disorders.

Methods
Genomic DNA was analysed using Sanger sequencing and next-generation sequencing (NGS). The Data was evaluated using various databases and in silico prediction tools and classified according to current ACMG standards by two independent experts.

Results
We identified 53 VUS in 30 genes, of which 17 variants (32%) were reclassified. 13% each were downgraded to likely benign (LB) and benign (B) and 6% were upgraded to likely pathogenic (LP). Reclassifications mainly occurred among variants initially classified in 2017–2019, with rates ranging from 50 to 60%.

Conclusion
The results support the assumption that regular reclassification of VUS is important, as it provides new insights for genetic diagnostics, that benefit patients and guide therapeutic approach.

AbstractBackgroundThe COVID-19 has been shown to have negative effects on the cardiovascular system, but it is unclear how long these effects last in college students. This study aimed to assess the long-term impact of COVID-19 on arterial stiffness, endothelial function, and blood pressure in college students.MethodsWe enrolled 37 college students who had been infected with COVID-19 for more than 2 months. Brachial artery flow-mediated dilation (FMD) was used to assess endothelial function, while arterial stiffness was evaluated using the ABI Systems 100, including variables such as ankle-brachial index (ABI), brachial-ankle pulse wave velocity (baPWV), carotid-femoral pulse wave velocity (cfPWV), heart rate (HR), and blood pressure (BP).ResultsOur results showed that FMD was significantly impaired after COVID-19 infection (p < 0.001), while cfPWV and systolic blood pressure (SBP) were significantly increased (p < 0.05). Simple linear regression models revealed a significant negative correlation between post-COVID-19 measurement time and baPWV change (p < 0.01), indicating an improvement in arterial stiffness over time. However, there was a significant positive correlation between post-COVID-19 measurement time and diastolic blood pressure (DBP) change (p < 0.05), suggesting an increase in BP over time. There were no significant differences in ABI and HR between pre- and post-COVID-19 measurements, and no significant correlations were observed with other variables (p > 0.05). Conclusion: Our study demonstrated that COVID-19 has long-term detrimental effects on vascular function in college students. However, arterial stiffness tends to improve over time, while BP may exhibit the opposite trend.
