Implementation of the My Abilities First Tool: A qualitative study on the perceptions of professionals, caregivers, children, and adolescents with disabilities.

OBJECTIVE: To analyze the perceptions of professionals, caregivers, children, and adolescents with disabilities regarding the implementation of the My Abilities First (MAF) tool in Specialized Child Rehabilitation Centers (CERs). METHOD: This is a qualitative research based on Reflexive Thematic Analysis (RTA). The study involved twenty-seven intentionally selected individuals, comprising 12 physiotherapists, 4 occupational therapists, 11 caregivers, 9 children and 2 adolescents. Participants completed sociodemographic and clinical questionnaires and took part in semi-structured online interviews, focusing on two themes: Positive health approaches and the MAF tool. The study was approved by the local ethics committee (opinion 4.779.175). RESULTS: Reflexive Thematic Analysis of the interviews resulted in two themes: (1) Perceptions regarding the MAF tool as an educational and contributory process to enhance the inclusion and participation of children and adolescents with disabilities, and (2) Barriers and facilitators for the implementation process of the MAF tool. The implementation of MAF was identified as a driving factor in promoting equity and increased participation of children and adolescents with disabilities in various settings, including health, education, and leisure. Interviewees highlighted the need to confront attitudinal, communication, and social barriers that may hinder the implementation of the tool. CONCLUSION: The implementation of the MAF tool was perceived as an innovation due to its focus on the abilities of individuals with disabilities. However, there is a need to restructure it to broaden its scope and access to different contexts in order to confront barriers and enhance the inclusion and participation of children and adolescents with disabilities.

Women Are Also Disadvantaged in Accessing Transplant Outside the United States: Analysis of the Spanish Liver Transplantation Registry.

Sex inequities in liver transplantation (LT) have been documented in several, mostly US-based, studies. Our aim was to describe sex-related differences in access to LT in a system with short waiting times. All adult patients registered in the RETH-Spanish Liver Transplant Registry (2000-2022) for LT were included. Baseline demographics, presence of hepatocellular carcinoma, cause and severity of liver disease, time on the waiting list (WL), access to transplantation, and reasons for removal from the WL were assessed. 14,385 patients were analysed (77% men, 56.2 ± 8.7 years). Model for end-stage liver disease (MELD) score was reported for 5,475 patients (mean value: 16.6 ± 5.7). Women were less likely to receive a transplant than men (OR 0.78, 95% CI 0.63, 0.97) with a trend to a higher risk of exclusion for deterioration (HR 1.17, 95% CI 0.99, 1.38), despite similar disease severity. Women waited longer on the WL (198.6 ± 338.9 vs. 173.3 ± 285.5 days, p < 0.001). Recently, women's risk of dropout has reduced, concomitantly with shorter WL times. Even in countries with short waiting times, women are disadvantaged in LT. Policies directed at optimizing the whole LT network should be encouraged to guarantee a fair and equal access of all patients to this life saving resource.

Occupational tasks associated with shoulder pain and upper extremity disability: a cross-sectional study in the Johnston County Osteoarthritis Project.

BACKGROUND: Shoulder pain is a leading cause of disability. Occupations requiring high upper extremity demands may put workers at greater risk of shoulder injury and resulting pain. We examined associations of occupation with shoulder pain and upper extremity disability in the Johnston County Osteoarthritis Project. METHODS: Work industry and occupational tasks for the longest job held were collected from participants. At follow-up ranging from 4-10 years later, participants were asked about shoulder symptoms (pain, aching, or stiffness occurring most days of 1 month in the last year) and given a 9-item, modified Disabilities Arm Shoulder and Hand (DASH) questionnaire to categorize disability from 0-4 (none-worst). Logistic regression and cumulative logit regression models were used to estimate associations with prevalent shoulder symptoms and with worse disability category, respectively. Models were adjusted for cohort, age, sex, race, education and time to follow-up. Sex- and race-stratified associations were evaluated. RESULTS: Among 1560 included participants, mean age was 62 years (standard deviation ± 9 years); 32% were men, and 31% were Black. Compared to the managerial/professional industry, higher odds of both shoulder symptoms and worse upper extremity disability were seen for most industrial groups with physically demanding jobs, particularly the service industry. Work that often or always required lifting/moving > 10 lbs. was associated with higher odds of shoulder symptoms. Work that sometimes or always required heavy work while standing was associated with higher odds of shoulder symptoms, and this association was stronger among men and White workers. CONCLUSION: Physically demanding occupations were associated with increased occurrence of shoulder pain and disability. Mitigating specific physical work demands may reduce shoulder-related disability.

Characterization of the interaction between the Sec61 translocon complex and ppαF using optical tweezers.

The Sec61 translocon allows the translocation of secretory preproteins from the cytosol to the endoplasmic reticulum lumen during polypeptide biosynthesis. These proteins possess an N-terminal signal peptide (SP) which docks at the translocon. SP mutations can abolish translocation and cause diseases, suggesting an essential role for this SP/Sec61 interaction. However, a detailed biophysical characterization of this binding is still missing. Here, optical tweezers force spectroscopy was used to characterize the kinetic parameters of the dissociation process between Sec61 and the SP of prepro-alpha-factor. The unbinding parameters including off-rate constant and distance to the transition state were obtained by fitting rupture force data to Dudko-Hummer-Szabo models. Interestingly, the translocation inhibitor mycolactone increases the off-rate and accelerates the SP/Sec61 dissociation, while also weakening the interaction. Whereas the translocation deficient mutant containing a single point mutation in the SP abolished the specificity of the SP/Sec61 binding, resulting in an unstable interaction. In conclusion, we characterize quantitatively the dissociation process between the signal peptide and the translocon, and how the unbinding parameters are modified by a translocation inhibitor.

Anxiety predicts math achievement in kindergarten children.

Introduction: Math anxiety (MA) is an academic anxiety about learning, doing, and evaluating mathematics, usually studied in school populations and adults. However, MA likely has its origins before children go to school. For example, studies have shown that general anxiety (GA) for everyday events is less separable from MA in primary than in early secondary school. This suggests that GA may be a precursor of MA. For this reason, here, we have examined whether GA is already associated with math achievement at the end of kindergarten. Methods: We tested 488 Hungarian kindergarten children aged 5.7 to 6.9 years (55% girls) and analyzed the effect of GA, sex, and family SES on math achievement in kindergarten children. Results: Strikingly, confirming results from primary school children, we found that GA negatively correlated with math achievement already in this preschool population. Higher GA levels had a stronger negative effect on girls' than boys' math achievement. However, there were no significant sex differences in math achievement in kindergarten. Additionally, family socioeconomic status was the strongest predictor of math achievement. Discussion: We speculate that high GA in preschool is a plausible early precursor of later high MA. Early interventions could aim to control GA levels before children start formal schooling.

Effects of the use of a cocoon on the autonomic, motor, and regulatory systems in preterm newborns: Randomized clinical trial.

INTRODUCTION: The wrapping of the newborn in an orthopedic tubular mesh, simulating a cocoon, can allow the infant to regain the feeling of security and stability experienced in the uterus given that the movement of one of the parts of the body exerts tactile and pressure variation in others. OBJECTIVE: We aimed to evaluate the influence of an orthopedic tubular mesh, simulating a cocoon, in therapeutic positioning, on the variables of the autonomous, motor, and regulatory systems of preterm newborns. METHODS: A controlled and randomized clinical trial was conducted with preterm newborns positioned in dorsal decubitus and divided into two groups: (a) cocoon - newborns covered with an orthopedic tubular mesh, and (b) control - newborns positioned according to the sector's routine and without the use of an orthopedic mesh. During the follow-up, each newborn was placed in the position for 30 min and was recorded for a total of 2 min, once at the beginning and again at the end of the observation period. Variables related to the autonomous system (heart rate, respiratory rate, and peripheral oxygen saturation), motor system (general movements), and regulatory system (Neonatal Infant Pain Scale) were evaluated before and after the intervention. The videos were evaluated by a researcher blind to the purpose of the study, and the resulting data were analyzed using SPSS. RESULTS: Of the 40 preterm newborns evaluated (32.5 ± 1.83 weeks), 21 were female, and 20 were allocated to the cocoon group. The variables related to the autonomous, motor, and regulatory systems remained unchanged following the positioning in the cocoon, as compared to the typical positioning employed in the neonatal unit. CONCLUSION: The simulation of a cocoon, utilizing an orthopedic tubular mesh, when applied to preterm newborns admitted to a neonatal intensive care unit can contribute to maintaining low levels of stress, without altering variables of the autonomous, motor, and regulatory systems.

Total mercury and selenium levels in commercial shrimp along the Pacific coast of Mexico.

The present study analyzed the content of total mercury (THg) and selenium (Se) in the muscle of shrimp collected from local markets in the 11 Pacific coastal states of Mexico. Methylmercury (MeHg) concentration, Se:Hg ratio, health benefits value from selenium consumption (HBVSe) and the permissible weekly consumption were estimated to assess the health risk to consumers. All THg and Se concentrations were below the maximum permissible limits. All hazard quotient (HQ) values were <1, however in Hermosillo, Culiacán and Guadalajara, the Se:Hg ratio and HBVSe were <1 and negative, due to the low concentrations of Se. As a general conclusion, there is no risk nor benefit from the consumption of shrimp from the Pacific coast of Mexico due to its Hg and Se content.

Contemporary and historical human migration patterns shape hepatitis B virus diversity.

Infection by hepatitis B virus (HBV) is responsible for approximately 296 million chronic cases of hepatitis B, and roughly 880,000 deaths annually. The global burden of HBV is distributed unevenly, largely owing to the heterogeneous geographic distribution of its subtypes, each of which demonstrates different severity and responsiveness to antiviral therapy. It is therefore crucial to the global public health response to HBV that the spatiotemporal spread of each genotype is well characterized. In this study, we describe a collection of 133 newly sequenced HBV strains from recent African immigrants upon their arrival in Belgium. We incorporate these sequences-all of which we determine to come from genotypes A, D, and E-into a large-scale phylogeographic study with genomes sampled across the globe. We focus on investigating the spatio-temporal processes shaping the evolutionary history of the three genotypes we observe. We incorporate several recently published ancient HBV genomes for genotypes A and D to aid our analysis. We show that different spatio-temporal processes underlie the A, D, and E genotypes with the former two having originated in southeastern Asia, after which they spread across the world. The HBV E genotype is estimated to have originated in Africa, after which it spread to Europe and the Americas. Our results highlight the use of phylogeographic reconstruction as a tool to understand the recent spatiotemporal dynamics of HBV, and highlight the importance of supporting vulnerable populations in accordance with the needs presented by specific HBV genotypes.

Tick-Borne Disease Infections and Chronic Musculoskeletal Pain.

Importance: Tick-borne diseases (TBDs) other than Lyme disease, such as spotted fever group rickettsiosis, ehrlichiosis, and galactose-α-1,3-galactose (α-gal) syndrome, are an emerging public health issue. Long-term sequelae secondary to Ehrlichia or Rickettsia infection are uncommon; however, musculoskeletal symptoms are often attributed to prior tick exposure. Objective: To evaluate the potential associations between prior exposure to TBDs and musculoskeletal symptoms, including radiographic osteoarthritis. Design, Setting, and Participants: This cross-sectional study analyzed serum samples from the fourth visit (2017-2018) of the Johnston County Osteoarthritis (JoCo OA) project, an ongoing longitudinal, population-based study in Johnston County, North Carolina. Biospecimen testing and analysis were performed between May 2022 and November 2023. Participants in the JoCo OA project are noninstitutionalized White and Black Johnston County residents 45 years or older. Main Outcome and Measures: The primary outcome was seropositivity with Ehrlichia IgG, Rickettsia IgG, and/or α-gal IgE and musculoskeletal symptoms. Secondary outcomes included risk factors associated with elevated α-gal IgE and weighted population point prevalence rates. Participants completed questionnaires, underwent physical assessments, and provided biospecimens for serological testing. Multivariable models were used to estimate associations of interest. Results: Of the 605 participants who completed the fourth visit of the JoCo OA project, 488 (80.7%) had serum samples available for testing. The 488 participants had a median (IQR) age of 72 (68-78) years and included 336 females (68.9%) and 161 Black (33.0%) and 327 White (67.0%) individuals. The overall weighted point prevalence was 8.6% (95% CI, 5.9%-11.3%) for Ehrlichia IgG, 17.1% (95% CI, 12.6%-21.5%) for Rickettsia IgG, and 19.6% (95% CI, 15.3%-23.8%) for α-gal IgE level greater than 0.1 IU/mL. Only α-gal IgE was associated with knee pain, aching or stiffness (mean ratio, 1.30; 95% CI, 1.09-1.56). Antibodies to Rickettsia, Ehrlichia, and α-gal were not associated with symptomatic radiographic knee osteoarthritis. Male sex (odds ratio [OR], 2.63; 95% CI, 1.55-4.47), current smoker status (OR, 3.55; 95% CI, 1.38-9.18), and an attached tick bite in the past 5 years (OR, 3.99; 95% CI, 2.22-7.15) were all risk factors that were associated with α-gal IgE level greater than 0.1 IU/mL. Despite only 84 individuals (17.2%) recalling a tick bite in the past 5 years, 178 (36.5%) had evidence of prior tick-borne exposure, suggesting frequent human-tick interactions. Conclusions and Relevance: Results of this cross-sectional study indicate no association between Ehrlichia or Rickettsia seropositivity and chronic musculoskeletal symptoms or osteoarthritis. Further investigation is needed into the pathogenesis of α-gal syndrome and interventions to reduce human-tick interactions.

Obesity is an independent risk factor for cancer development following diagnosis of dermatomyositis.

Patients with dermatomyositis (DM) are at an increased risk of cancer development, especially around the time of diagnosis of DM. Obesity is also a risk factor in the general population for cancer development. This study aimed to assess the association between cancer in DM patients with and without obesity as defined by ICD code and BMI data. In this analysis of patients with DM, logistic regression modeling of the odds of cancer outcome was performed for patients with DM and obesity compared to those without obesity, adjusted for age and sex. A total of 12,722 patients with DM were identified, of whom 6,055 had available BMI data. DM patients who were coded obese at any point had significantly higher odds 1.98 (95 % Confidence interval (CI) 1.70, 2.30) of a subsequent cancer diagnosis. This association was also found in the subgroup analysis with available BMI where patients with obesity (BMI ≥30 kg/m2) had an increased odds of cancer 1.23 (1.02, 1.49) when compared to patients with BMI <30 kg/m2 with DM. In time to event analysis any obesity code was associated with a 16 % increased hazard of cancer (adjusted hazard ratio 1.16 [95 % CI 1.02, 1.31]). Overall, the most frequent type of cancer was breast cancer, however patients with DM and obesity had higher frequencies of lymphoma, colorectal, melanoma, uterine, renal cancers compared to patients with DM without obesity.

Features of Knee and Multijoint Osteoarthritis by Sex and Race and Ethnicity: A Preliminary Analysis in the Johnston County Health Study.

OBJECTIVE: To evaluate knee osteoarthritis (KOA) and multijoint osteoarthritis (MJOA), and to compare features by sex and race and ethnicity in a population-based cohort. METHODS: Participants (n = 544) enrolled in the Johnston County Health Study (JoCoHS) as of January 2023 were categorized by radiographic and symptomatic KOA and MJOA phenotypes, and frequencies were compared by sex and race and ethnicity. Symptoms were assessed according to the Knee Injury and Osteoarthritis Outcome Score (KOOS) and pain, aching, and stiffness (PAS) scores at various joints. Models produced estimates (odds ratio [OR] or mean ratios [MR] and 95% CI) adjusted for age, BMI (kg/m2), and education. RESULTS: Men had twice the odds of having MJOA-6 (≥ 3 lower extremity joints affected); there were no significant differences in MJOA phenotypes by race and ethnicity. Women had 50% higher odds of having KOA or having various features of KOA. Women reported significantly worse KOOS Symptoms scores (MR 1.25). Black participants had higher odds of more severe KOA (OR 1.47), subchondral sclerosis (OR 2.06), and medial tibial osteophytes (OR 1.50). Black participants reported worse KOOS Symptoms than White participants (MR 1.18). Although not statistically significant, Hispanic participants (vs non-Hispanic participants) appeared to have lower odds of radiographic changes but reported worse symptoms. CONCLUSION: Preliminary findings in the diverse JoCoHS cohort suggest more lower extremity- predominant MJOA in men compared to women. Women and Black participants had more KOA features and more severe symptoms. Hispanic participants appear to have higher pain and symptoms scores despite having fewer structural changes. Studies in diverse populations are needed to understand the burden of OA.

Higher Odds of Adverse Cutaneous Reactions in Patients With Dermatomyositis Treated With Hydroxychloroquine Compared With Methotrexate.

OBJECTIVE: Hydroxychloroquine (HCQ) use for the treatment of dermatomyositis (DM) has been associated with adverse cutaneous reactions. We applied a new user, active comparator, retrospective design to assess differences in adverse cutaneous reactions or hospitalizations between HCQ and methotrexate (MTX) use among patients with DM. METHODS: We used a national network of data from insurance registries (TriNetX), enrolling patients with two International Classification of Diseases (ICD) codes for DM separated by 6 months or more who had a prescription for either (but not both) HCQ or MTX on or after DM diagnosis. Outcomes were adverse cutaneous reactions (ICD codes) or hospital admission (Current Procedural Terminology (CPT) codes) within 4 months from the prescription dispense date. Logistic regression was used to produce adjusted odds ratios (aORs) and 95% confidence intervals (CIs) comparing outcomes in the HCQ group (n = 1364) and the MTX group (n = 1400), adjusted for age at first DM diagnosis, year of birth, sex, and time from DM diagnosis to first prescription. RESULTS: Overall, we found no significant difference in odds of hospitalization in those taking HCQ (aOR 1.05; 95% CI: 0.79-1.39) compared with those on MTX. Patients with DM on HCQ had 30% higher odds of adverse cutaneous reaction diagnosis compared with patients on MTX (aOR 1.30; 95% CI: 1.02-1.59). Age at DM diagnosis was an effect modifier of this association, with higher odds of adverse cutaneous reaction among patients taking HCQ who were younger at diagnosis. CONCLUSION: Compared with MTX use, HCQ use, especially in younger patients, may result in higher odds of adverse cutaneous reactions.

Effect of an action-research nutrition intervention on the Global Diet Quality Score of Colombian adolescents.

Strategies to address the nutritional needs of adolescent girls and young women often focus on supplementation. In this study, an action-research approach involving a nutrition education and entrepreneurship intervention was carried out among adolescent girls and young women in poor neighborhoods of Medellín, Colombia. The intervention group significantly increased its intake of several nutrients, including energy, protein, total fat, saturated fat, monounsaturated fat, polyunsaturated fat, cholesterol, dietary fiber, calcium, zinc, and vitamins A, B2, B3, B9, and C. A significant increase was observed in the intake of the Global Diet Quality Score (GDQS) healthy food groups (other fruits, other vegetables, legumes, high-fat dairy products), accompanied by a decrease in the consumption of some unhealthy food groups (sweets and ice creams). A multivariate regression controlling for age, socioeconomic status, occupation, Household Hunger Scale, mean probability of adequacy, physical activity, and body self-perception showed that the nutrition intervention improved the total GDQS by 33% in the intervention group-a substantial improvement notwithstanding the study group's precarious social and economic conditions. We conclude that nutrition education and entrepreneurship models based on this approach may improve the dietary profile of this population and reduce future pressures from nutrition-related chronic diseases.

Salvage of a Fractured Proximal Ulnar Osteoarticular Allograft Using a Medial Femoral Condyle Free Flap: A Case Report.

CASE: We present the case of a 47-year-old paraplegic woman who underwent resection of an intermediate-grade chondrosarcoma in the proximal ulna, which was initially reconstructed with an osteoarticular allograft. However, after more than 25 years without complications, she sustained an intra-articular fracture of the allograft, which was then successfully treated using a vascularized medial femoral condyle (MFC) flap and anterolateral thigh flap. The patient has subsequently recovered her baseline elbow function, has no pain, and can use her wheelchair without restrictions. CONCLUSION: Free MFC flaps are viable options to salvage osteoarticular allografts that are affected by intra-articular fractures.

TTCC-2019-02: real-world evidence of first-line cetuximab plus paclitaxel in recurrent or metastatic squamous cell carcinoma of the head and neck.

Objectives: The aim of this study was to confirm the efficacy of the ERBITAX scheme (paclitaxel 80 mg/m2 weekly and cetuximab 400 mg/m2 loading dose, and then 250 mg/m2 weekly) as first-line treatment for patients with recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN) who are medically unfit for cisplatin-based (PT) chemotherapy. Materials and methods: This retrospective, non-interventional study involved 16 centers in Spain. Inclusion criteria were to have started receiving ERBITAX regimen from January 2012 to December 2018; histologically confirmed SCCHN including oral cavity, oropharynx, hypopharynx, and larynx; age ≥18 years; and platinum (PT) chemotherapy ineligibility due to performance status, comorbidities, high accumulated dose of PT, or PT refractoriness. Results: A total of 531 patients from 16 hospitals in Spain were enrolled. The median age was 66 years, 82.7% were male, and 83.5% were current/former smokers. Patients were ineligible to receive PT due to ECOG 2 (50.3%), comorbidities (32%), PT cumulative dose ≥ 225 mg/m2 (10.5%), or PT refractoriness (7.2%). Response rate was 37.7%. Median duration of response was 5.6 months (95% CI: 4.4-6.6). With a median follow-up of 8.7 months (95% CI: 7.7-10.2), median PFS and OS were 4.5 months (95% CI: 3.9-5.0) and 8.9 months (95% CI: 7.8-10.3), respectively. Patients treated with immunotherapy after ERBITAX had better OS with a median of 29.8 months compared to 13.8 months for those who received other treatments. The most common grade ≥ 3 toxicities were acne-like rash in 36 patients (6.8%) and oral mucositis in 8 patients (1.5%). Five (0.9%) patients experienced grade ≥ 3 febrile neutropenia. Conclusion: This study confirms the real-world efficacy and tolerability of ERBITAX as first-line treatment in recurrent/metastatic SCCHN when PT is not feasible. Immunotherapy after treatment with ERBITAX showed remarkable promising survival, despite potential selection bias.

Comparison between Wright and Shukla formulas: which is better for the placement of umbilical catheters in newborns ≤ 1500 g?

BACKGROUND: Intravascular venous (VUC) or arterial (AUC) umbilical catheter placement is the most frequent invasive procedure in the neonatal intensive care unit (NICU). Either Wright's or Shukla's formula is used to introduce the catheters. However, Shukla's formula is associated with incorrect insertion, especially for newborns < 1500 g. This study aimed to determine by chest X-ray if Wright's formula is better than Shukla's formula for the correct placement of umbilical catheters in newborns ≤ 1500 g. METHODS: We included patients admitted to the NICU of a secondary-level hospital between 2021-2022 who received VUC or AUC through the Wright or Shukla formulas. RESULTS: A total of 129 newborns were included: 78 with VUC and 51 with AUC. In VUC, 50% with Wright and 36.8% with Shukla formulas had the correct location, (p = 0.24). In AUC, 56.6 % with Wright and 52.4% with Shukla formulas were placed correctly placed, (p = 0.76). VUC with weight < 1000 g were correctly placed in 36.4% with Wright and 33.3% with Shukla formulas (p = 0.58). VUC in newborns > 1000 g were correctly placed in 66.6% with Wright and 38.4% with Shukla formulas (p = 0.065). AUC in newborns < 1000 g were correctly placed in 45% using Wright and 42.9% Shukla formulas (p = 0.63). AUC in newborns > 1000 g were correctly placed in 80% using Wright and 57.1% Shukla formulas (p = 0.23). CONCLUSIONS: We found 13% more correctly placed VUC using Wright's formula. Moreover, Wright's formula was 29% above Shukla's VUC placement in neonates > 1000 g, although there was no significant difference due to the sample size.

INTRODUCCIÓN: La colocación de catéteres intravasculares venosos umbilicales (CVU) y arteriales (CAU) es el procedimiento invasivo más frecuente en la unidad de cuidados intensivos neonatales (UCIN). Para introducirlos se utilizan las fórmulas de Wright y de Shukla, aunque esta última podría estar asociada con una inserción incorrecta, especialmente en neonatos < 1500 g. El objetivo de este estudio fue determinar mediante radiografía de tórax cuál fórmula es mejor para la correcta colocación de catéteres umbilicales en recién nacidos ≤ 1500 g. MÉTODOS: Se incluyeron los pacientes ingresados en la UCIN de un hospital de segundo nivel entre 2021-2022 que recibieron CVU o CAU mediante las fórmulas de Wrigth o Shukla. RESULTADOS: Se incluyeron en total 129 recién nacidos: 78 CVU y 51 CAU. En CVU, Wright 50% y Shukla 36.8% tuvieron localización correcta, p = 0.24. En las CAU, Wright 56.6% y Shukla 52.4% tenían una ubicación correcta, p = 0.76. En CVU con peso < 1000 g, Wright 36.4% y Shukla 33.3% bien situados, p = 0.58. En CVU > 1000 g, Wright 66.6% y Shukla 38.4% bien situados, p = 0.065. En CAU < 1000 g, Wright 45% y Shukla 42.9%, p = 0.63. En CAU con peso > 1000 g, Wright 80% y Shukla 57.1%, p = 0.23. CONCLUSIONES: La colocación del CVU fue 13% mejor con la fórmula de Wright. La fórmula de Wright superó en el 29% la colocación del CVU en los neonatos > 1000 g en comparación con la de Shukla, aunque no hubo diferencia significativa debido al tamaño de la muestra.

Association of Foot Symptoms With Decreased Time to All-Cause Mortality: The Johnston County Osteoarthritis Project.

OBJECTIVE: Adults with foot symptoms (ie, pain, aching, or stiffness) may be at increased risk of reduced time to all-cause mortality. The purpose of this study was to evaluate whether foot symptoms are independently associated with all-cause mortality in older adults. METHODS: We analyzed longitudinal data from 2613 participants from the Johnston County Osteoarthritis Project, a longitudinal population-based cohort of adults 45 years of age and older. Participants completed questionnaires at baseline to determine presence of foot symptoms and covariable status. Baseline walking speed was measured via an 8-foot walk test. To examine the association of foot symptoms with time to mortality, hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox regression models, adjusted for potential confounders. RESULTS: We observed 813 deaths over 4 to 14.5 years of follow-up. At baseline, 37% of participants had foot symptoms, mean age was 63 years, mean body mass index was approximately 31 kg/m2 , 65% were women, and 33% were Black. Moderate to severe foot symptoms were associated with reduced time to mortality after adjustment for demographics, comorbidities, physical activity, and knee and hip symptoms (HR = 1.30, 95% CI 1.09-1.54). Importantly, this association was not modified by walking speed or diabetes. CONCLUSION: Individuals with foot symptoms had an increased hazard of all-cause mortality compared with those with no foot symptoms. These effects were independent of key confounders and were not moderated by walking speed. Effective interventions to identify and manage at least moderate foot symptoms may reduce the risk of decreased time to mortality.

The Slipper Fracture: Revisited.

Objectives The term "slipper fracture" is used to describe a fracture of the radius at the junction of the metaphysis and diaphysis. This fracture has an "evil" reputation because it often angulates in the cast. Historically, there have been differing opinions on the optimal way to cast slipper fractures either with a long arm cast in pronation or a long arm cast in supination to prevent angulation. The purpose of this study is to report the outcomes of "slipper fractures" treated with casting. Methods Sixteen slipper fractures were retrospectively reviewed. Electronic medical records (EMRs) and radiographs were analyzed to gather data on body weight, cast type, cast position, cast index, loss of reduction, cast wedging, repeat reduction, surgery, and amount of remodeling. Results The average age of the patients was eight years old. The average body weight was 30.4 kg. Initial casting included 14 long arm casts in neutral, one short arm cast, and one sugar tong splint. The average cast index was 0.87. Only one cast had a cast index of less than 0.8. This fracture was treated with a long arm cast and did not displace. Of the fractures, 94% lost reduction in the cast and angulated an average of 26 degrees. Two cases were treated with a cast wedge; 13 were observed. Remodeling occurred at an average rate of 2.7 degrees/month. The average remodeling measured at the last follow-up was 15 degrees. Conclusion Slipper fractures are difficult to treat due to the angulation of the fracture in the cast. The current study indicates that a long arm cast, appropriate cast index, and cast position are key to preventing the loss of reduction or angulation of a slipper fracture.

The impact of obesity on postoperative complications and short-term survival after liver transplantation.

BACKGROUND AND AIMS: Obesity is considered a risk factor for perioperative complications, but its effect on patients undergoing liver transplantation (LT) remains unclear. This study was conducted to analyze the impact of obesity on early morbidity and mortality risk following LT. METHODS: A multicenter study of outcomes in patients submitted to LT between 2009 and 2019 was conducted. Recipients were stratified into obese (BMI ≥ 30 kg/m2) and nonobese patients (BMI < 30 kg/m2). Early postoperative complications were compared and 30-day and 1-year patient and graft survival were assessed by Kaplan-Meier method. Primary graft nonfunction (PGNF) was defined as the presence of total bilirubin > 10 mg/dl, INR > 1.6 or ALT > 2000 U/l within the first week after LT. RESULTS: A total of 1608 patients were included after applying exclusion criteria, nonobese (1149, 71.46%) and obese patients (459, 28.54%). There were no significant differences in age, sex, Model for End-stage Liver Disease, Charlson comorbidity score, ethnicity, waiting list time and ischemia time. There were significantly higher rates of vascular (17.58% vs 23.53%, P = 0.021) and biliary complications (27.68% vs 35.73%, P = 0.006) and PGNF (11.40% vs 12.20%, P = 0.021) in obese patients. There was a significantly increased risk for long-term graft failure; however, there was no significant difference in patient survival after LT. CONCLUSION: Obese patients have significantly increased morbidity in terms of vascular and biliary complications and PGNF after LT. They have a higher risk for worse 1-year graft survival in comparison to controls.

Comparison between Wright and Shukla formulas: which is better for the placement of umbilical catheters in newborns ≤ 1500 g? / Comparación entre las fórmulas de Wright y de Shukla: ¿cuál es mejor para la colocación de catéteres umbilicales en recién nacidos ≤ 1500 g?

Abstract Background: Intravascular venous (VUC) or arterial (AUC) umbilical catheter placement is the most frequent invasive procedure in the neonatal intensive care unit (NICU). Either Wright's or Shukla's formula is used to introduce the catheters. However, Shukla's formula is associated with incorrect insertion, especially for newborns < 1500 g. This study aimed to determine by chest X-ray if Wright's formula is better than Shukla's formula for the correct placement of umbilical catheters in newborns ≤ 1500 g. Methods: We included patients admitted to the NICU of a secondary-level hospital between 2021-2022 who received VUC or AUC through the Wright or Shukla formulas. Results: A total of 129 newborns were included: 78 with VUC and 51 with AUC. In VUC, 50% with Wright and 36.8% with Shukla formulas had the correct location, (p = 0.24). In AUC, 56.6 % with Wright and 52.4% with Shukla formulas were placed correctly placed, (p = 0.76). VUC with weight < 1000 g were correctly placed in 36.4% with Wright and 33.3% with Shukla formulas (p = 0.58). VUC in newborns > 1000 g were correctly placed in 66.6% with Wright and 38.4% with Shukla formulas (p = 0.065). AUC in newborns < 1000 g were correctly placed in 45% using Wright and 42.9% Shukla formulas (p = 0.63). AUC in newborns > 1000 g were correctly placed in 80% using Wright and 57.1% Shukla formulas (p = 0.23). Conclusions: We found 13% more correctly placed VUC using Wright's formula. Moreover, Wright's formula was 29% above Shukla's VUC placement in neonates > 1000 g, although there was no significant difference due to the sample size.

Resumen Introducción: La colocación de catéteres intravasculares venosos umbilicales (CVU) y arteriales (CAU) es el procedimiento invasivo más frecuente en la unidad de cuidados intensivos neonatales (UCIN). Para introducirlos se utilizan las fórmulas de Wright y de Shukla, aunque esta última podría estar asociada con una inserción incorrecta, especialmente en neonatos < 1500 g. El objetivo de este estudio fue determinar mediante radiografía de tórax cuál fórmula es mejor para la correcta colocación de catéteres umbilicales en recién nacidos ≤ 1500 g. Métodos: Se incluyeron los pacientes ingresados en la UCIN de un hospital de segundo nivel entre 2021-2022 que recibieron CVU o CAU mediante las fórmulas de Wrigth o Shukla. Resultados: Se incluyeron en total 129 recién nacidos: 78 CVU y 51 CAU. En CVU, Wright 50% y Shukla 36.8% tuvieron localización correcta, p = 0.24. En las CAU, Wright 56.6% y Shukla 52.4% tenían una ubicación correcta, p = 0.76. En CVU con peso < 1000 g, Wright 36.4% y Shukla 33.3% bien situados, p = 0.58. En CVU > 1000 g, Wright 66.6% y Shukla 38.4% bien situados, p = 0.065. En CAU < 1000 g, Wright 45% y Shukla 42.9%, p = 0.63. En CAU con peso > 1000 g, Wright 80% y Shukla 57.1%, p = 0.23. Conclusiones: La colocación del CVU fue 13% mejor con la fórmula de Wright. La fórmula de Wright superó en el 29% la colocación del CVU en los neonatos > 1000 g en comparación con la de Shukla, aunque no hubo diferencia significativa debido al tamaño de la muestra.
