Fecal glycoprotein 2 is a marker of gut microbiota dysbiosis and systemic inflammation

BackgroundAntimicrobial autoantigenic glycoprotein 2 (GP2) is an important component of the innate immune system which originates from the exocrine pancreas as well as from the small intestines. The relationship of GP2 with the intestinal microbiome as well as the systemic implications of increased fecal GP2 levels are, however, still unclear. Therefore, fecal samples from 2,812 individuals of the Study of Health in Pomerania (SHIP) were collected to determine GP2 levels (enzyme-linked immunosorbent assay) and gut microbiota profiles (16 S rRNA gene sequencing). These data were correlated and associated with highly standardised and comprehensive phenotypic data of the study participants.ResultsFecal GP2 levels were increased in individuals with higher body mass index and smokers, whereas lower levels were found in case of preserved exocrine pancreatic function, female sex or a healthier diet. Moreover, higher GP2 levels were associated with increased serum levels of high-sensitivity C-reactive protein, loss of gut microbial diversity and an increase of potentially detrimental bacteria (Streptococcus, Haemophilus, Clostridium XIVa, or Collinsella). At the same time, predicted microbial pathways for the biosynthesis of beneficial short-chain fatty acids or lactic acid were depleted in individuals with high fecal GP2. Of note, GP2 exhibited a stronger association to overall microbiome variation than calprotectin.ConclusionFecal GP2 is a biomarker of gut microbiota dysbiosis and associated with increased systemic inflammation. The intestines may be more important as origin for GP2 than pancreatic acinar cells. Future studies need to investigate the potential clinical value in disease specific patient cohorts.

Cognitive functions explain discrete parameters of normal walking and dual-task walking, but not postural sway in quiet stance among physically active older people.

Postural control is dependent on the central nervous system's accurate interpretation of sensory information to formulate and execute adequate motor actions. Research has shown that cognitive functions are associated with both postural control and fall risk, but specific associations are not established. The aim of this study was to explore how specific components of everyday postural control tasks are associated with both general and specific cognitive functions. Forty-six community-dwelling older adults reported their age, sex, physical activity level, falls and fall-related concerns. The following cognitive aspects were assessed: global cognition, executive functions, processing speed and intraindividual variability. Postural control was quantified by measuring postural sway in quiet stance, walking at a self-selected pace, and walking while performing a concurrent arithmetical task. Separate orthogonal projections of latent structures models were generated for each postural control outcome using descriptive and cognitive variables as explanatory variables. Longer step length and faster gait speed were related to faster processing speed and less intraindividual variability in the choice reaction test. Moreover, longer step length was also related to less fall-related concerns and less severe fall-related injuries, while faster gait speed was also related to female sex and poorer global cognition. Lower dual-task cost for gait speed was explained by the executive function inhibition and faster processing speed. Postural sway in quiet stance was not explained by cognitive functions. Cognitive functions explained gait speed and step length during normal walking, as well as the decrease of gait speed while performing a concurrent cognitive task. The results suggest that different cognitive processes are important for different postural control aspects. Postural sway in quiet stance, step time and gait variability seem to depend more on physical and automatic processes rather than higher cognitive functions among physically active older people. The relationships between cognitive functions and postural control likely vary depending on the specific tasks and the characteristics of different populations.

Identifying the ‘Miserable Minority’ Among Pediatric Patients Following Concussion

ObjectivesTo investigate whether there are empirically-detectable subgroups of concussion severity and recovery across three consecutive concussions, as well as to define risk factor and clinical assessment differences across subgroups. MethodsThe present study was a retrospective chart review of 202 adolescents 13.17 ± 1.99 years old who presented to a concussion specialty clinic within 30 days of injury for multiple injuries between 2019 and 2020. Participants included patients from a specialty clinic for two (n = 202) or three (n = 68) total concussions. Latent class analysis (LCA) was used to identify subgroups based upon concussion symptom severity and recovery time. Risk factors (sex, age at first injury, and histories of anxiety, depression, migraine, motion sickness, ocular dysfunction, and attention-deficit/hyperactivity disorder [ADHD] or learning disability [LD]) were compared across subgroups. ResultsA two-class solution yielded one group of 163 participants characterized by lower symptoms and shorter recovery times (80.7%, “normal”) and 39 participants (19.3%, “miserable minority”) characterized by higher symptoms and longer recovery times. Only female sex (OR = 4.91, p = 0.005) was a significant predictor of class membership. The miserable group presented for treatment nearly 4 days later (9.41 days) compared to the normal group (5.74 days) for the first injury, and almost 2 days later for the second injury (7.33 vs 5.26 days). ConclusionsApproximately 1 in 5 patients who presented to a concussion specialty clinic for a repeat concussion were classified in the miserable minority subgroup. This subgroup was characterized by markedly higher initial symptom burdens and over double the recovery time. Level of EvidenceRetrospective cohort study, Level III evidence.

Nurses' perceptions of caring behaviors at referral hospitals in Ethiopia: A mixed-methods approach.

Caring plays a vital role in nursing and serves as an indicator of quality. Nurse caring behaviors are directed towards patients' safety and wellbeing. Nurses' perceptions of caring behaviors are affected by different factors. Understanding the factors linked to how nurses perceive caring behaviors is crucial for enhancing the quality of care. The aim of this study was to examine the factors associated with nurses' perceptions of caring behaviors and gain a more comprehensive understanding. A multicenter sequential explanatory mixed-methods study was conducted among medical-surgical nurses at three referral hospitals in the Amhara region, Ethiopia. Quantitative data were collected using a pretested self-administered survey package including the Amharic version of the Caring Behaviors Inventory-16. Qualitative interviews using semi-structured, open-ended questions were conducted after the survey to complement and clarify the quantitative results, facilitating integrate through a connecting approach. A multiple linear regression model was used to examine the relationship between nurses' perceptions of caring behaviors and associated factors. The qualitative data was examined to find meaningful patterns using codebook thematic analysis. This method was deductive and followed the guidelines by Braun and Clarke, building on the findings from the quantitative results. The overall mean of nurses' perceptions of caring behaviors was 4.75. The multiple linear regression analysis showed that female sex (b = 0.300, P = 0.004), age (b = 0.028, P = 0.001), nurse staffing (b=-0.115, P = 0.001), work-related stress (b = 0.298, P = 0.003), and job satisfaction (b=-0.254, P = 0.016) were associated with nurses' perceptions of caring behaviors. The codebook thematic analysis generated three themes, caring is universal and fundamental in nursing, impediments to provision of comprehensive care, and perception of the work conditions. The findings of the qualitative data complemented the results of the quantitative data. Discrepancies between nurses' expectations and the actual working environment may create uncertainty in care provision and impact quality-of-care. Strategies to harmonize the nurses' working environment should consider work-related factors.

Intravascular Lithotripsy for Peripheral Artery Calcification: 30-Day Outcomes From the Disrupt PAD III Observational Study.

Intravascular lithotripsy (IVL) has shown promising safety and effectiveness in calcified peripheral artery disease (PAD) in large trials and small real-world experiences. Real-world evidence from a larger cohort is lacking, so we aimed to evaluate the real-world acute performance of IVL in the treatment of calcified PAD. The Disrupt PAD III Observational Study (OS) is a prospective, multicenter, single-arm study. Patients with claudication or critical limb-threatening ischemia (CLTI) and at least moderate calcification were eligible. Independent predictors of procedural outcomes were assessed by multivariable analysis. Between November 2017 and June 2021 across 30 global sites, 1373 patients with 1677 lesions (1531, 91.3% core lab evaluable) were enrolled. Diameter stenosis and lesion length was 80.6±17.6% and 93.5±74.3 mm, respectively. Target vessels included femoropopliteal (61%), iliac (15.8%), common femoral (10.7%), and infrapopliteal arteries (12.8%). Lesion characteristics included 31.1% chronic total occlusions (CTOs) and 19.3% long lesions (≥15 cm). At final assessment, residual stenosis was 23.8±11.3%, with 0.9% serious angiographic complications, no abrupt closures, distal embolization, no flow, or thrombotic events. Independent predictors of ≤30% residual stenosis were lesion length ≥15 cm (odds ratio [OR]=0.384), female sex (OR=1.850), age ≤75 years (OR=1.625), IVL balloon to artery ratio ≥1.0 (OR=1.538), and CTO lesions (OR=0.638). Lesion length ≥15 cm (OR=16.076) was an independent predictor of procedural complications. The Disrupt PAD III OS represents the largest assessment of IVL periprocedural outcomes in calcified PAD. It confirmed excellent procedural safety and effectiveness in complex lesions across multiple peripheral vascular beds. This final analysis of the PAD III OS represents the largest report of peripheral IVL utilization in daily clinical practice. The outcomes of this study indicate that previously reported procedural results in clinical trial settings can be translated to a broader patient population. Treatment with peripheral IVL in severely calcified stenotic lower limb lesions demonstrated consistent acute safety and stenosis reduction, even in complex patients across multiple vessel beds. In addition, the importance of proper IVL balloon sizing to achieve excellent acute stenosis reduction was confirmed by multivariate analysis.

A Risk Tool for Evaluating Overuse Injury and Return-to-Play Time Periods in Youth and Collegiate Athletes: Preliminary Study.

Overuse injuries in youth athletes are associated with risks, including sports specialization, biological maturation, female sex, and workload measures. As no assessment tool exists to evaluate risk accumulation, we developed a novel risk factor scoring system (Sport Training Assessment of Risk [STAR]) to assess participants' risk of overuse injury and explore association with return-to-play (RTP) time periods. (1) STAR will reach an acceptable predictive threshold in the assessment of overuse injury in youth athletes. (2) Higher STAR scores will be associated with increased RTP time periods after injury. Longitudinal cohort study. Level 3. Youth athletes with an injury sustained during competitive sport completed questionnaires. Association of questionnaire variables with injury risk type was evaluated via logistic regression analyses, and unweighted and weighted versions of a total risk score were developed. RTP was defined by physician clearance per electronic medical record review. Mantel-Haenszel chi-square tests and Kendall's rank correlation coefficients were used to assess the relationship between weighted total risk score and RTP time periods. The weighted STAR model was analyzed with receiver operating characteristic (ROC) curves. The weighted STAR model trended toward an acceptable level of prediction for overuse (nonserious + serious) injury (area under the ROC curve [AUC], 0.66; 95% CI, 0.61-0.71), but was less predictive for serious overuse injury (AUC, 0.63; 95% CI, 0.55-0.71). Weighted total risk score was weakly associated with return to full play (ρ = 0.11; P < 0.01), and potentially with return to modified play (ρ = -0.08; P = 0.04). STAR may be a feasible tool for assessing overuse injury risk and RTP time periods in youth athletes but requires further development, as it did not reach an acceptable predictive threshold in this preliminary study. Clinicians can use STAR to assess overuse injury risk in youth athletes.

Crimean Congo hemorrhagic fever virus exposure among febrile patients, cattle herders, and cattle herds in Cameroon

Problem addressedCrimean Congo hemorrhagic fever (CCHF) is a tick-borne disease with high fatality rates and an expansive geographic distribution, yet disease prevalence data in Cameroon is lacking. ObjectiveThis study aimed to determine CCHF virus (CCHFV) seroprevalence and tick distribution among cattle herders and febrile patients in West and Centre Cameroon. Methods and approachTwo cross-sectional serological studies of human and cattle were conducted from October to December 2021 and from June to July 2022, which included the collection of ticks. Enzyme-linked immunosorbent assay (ELISA) were used to detect anti-CCHFV antibodies, while a knowledge, attitudes, and practice (KAP) survey assessed tick and tickborne disease related knowledge and behaviors among herders. Tick identification used morphological keys. ResultsThe KAP survey showed adequate tick knowledge (94.5 %) among herders but poor understanding of disease transmission, with favorable attitudes towards tick control (24.7 %) but inadequate implementation. Rhipicephalus annulatus (64.1 %) predominated among the 1,296 ticks collected during each rainy season. Among cattle, 27.4 % were seropositive, and seropositivity was associated with specific villages, cattle age (>4 years), and female sex. Herders had a 17.8 % seroprevalence, while febrile patients had 8.3 %, with higher rates in those >20 years old for both groups. Self-reported tick removal by herders after contact and grazing may increase CCHFV exposure. ConclusionsThis study confirms CCHFV circulation in rural West Cameroon and unexpected exposure risk in Yaounde, highlighting the need for active entomological surveillance and preventive measures in transhumance and cattle market activities. Establishing an occupation-based surveillance system can help identify CCHFV hotspots to prevent outbreaks.

Incidence and Predictors of HBsAg Loss in Paediatric Patients With Chronic Hepatitis B Undergoing Antiviral Treatment.

Achieving HBsAg loss is a critical clinical milestone in the management of chronic hepatitis B (CHB) towards the eradication of hepatitis B. However, there are limited researches on the incidence and determinants of HBsAg loss in paediatric CHB patients undergoing antiviral treatment. Therefore, we aimed to analyse the incidence and potential determinants of HBsAg loss in children who suffered from CHB and received antiviral treatment. This retrospective cohort study was performed on paediatric patients with progressive CHB who initiated either monotherapy or combination therapy using interferon/peg-interferon and entecavir. We utilised Cox regression models to evaluate the relationships between HBsAg loss and various determining factors. In total of 306 subjects with an average age of 4.99 years (range 1-15) were identified in this study, of whom 200 (65.4%) were male. After a median follow-up of 26 months, HBsAg loss occurred in 135 participants. The accumulated rate of HBsAg loss was 67.8% at the end of the follow-up evaluation. Multivariate Cox regression analysis revealed that older age (HR = 0.84, 95% CI: 0.79-0.90), female sex (HR = 1.61, 95% CI: 1.13-2.30), baseline HBsAg levels (HR = 0.72, 95% CI: 0.62-0.84), HBsAb positivity (HR = 1.77, 95% CI: 1.20-2.59) and serum bilirubin levels (HR = 0.96, 95% CI: 0.92-0.99) were statistically significant predictors of HBsAg loss. The incidence of HBsAg loss continues to increase in paediatric patients with CHB after antiviral treatment. Age, sex, baseline HBsAg and bilirubin levels and HBsAb positivity are found to be associated with sustained HBsAg loss.

Direct-Acting Oral Anticoagulants and Potential Inconsistencies with FDA-Approved Dosing for Non-Valvular Atrial Fibrillation: A Retrospective Real-World Analysis Across Nine US Healthcare Systems.

Direct-acting oral anticoagulants (DOACs) are recommended to reduce risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation (NVAF). However, DOAC dosing inconsistent with FDA-approved product labels is common and associated with poor clinical outcomes. Identify DOAC dosing inconsistent with FDA-approved product labels in ambulatory care patients with NVAF; identify variables associated with dosing lower and higher than label. Retrospective analysis using electronic health records from nine US healthcare systems. Adults with NVAF receiving DOAC therapy in 2022. Rates of label-inconsistent dosing; multivariable regression analysis to identify demographic and clinical variables associated with dosing lower and higher than label. Among 51,128 NVAF patients (56.1% male, 94.3% White, mean [SD] age 73.5 [10.5] years), 5008 (9.8%) were prescribed label-inconsistent doses of DOACs (6.8% lower and 3.0% higher than label). Age ≥ 75years, renal impairment, and hypertension were significantly associated with inconsistent dosing both higher and lower than label. Female sex and higher weight were significantly associated with dosing lower than label, as were heart failure, vascular or liver disease, and bleeding history. Dosing higher than label was significantly associated with male sex, race (African American/Black), weight < 60kg, and use of drugs with potential drug-drug interactions. When prescribed by primary care physicians, DOAC doses were 37% (95% CI, 27-49%) more likely to be lower than label and 30% (95% CI, 16-46%) more likely to be higher than label than when prescribed by cardiologists or electrophysiologists. Label-inconsistent dosing varied (6.7 to 15.8%) across participating systems. DOAC dosing inconsistent with label varied by demographics, clinical characteristics, prescriber specialty, and healthcare system, suggesting a need to monitor and assess dosing decisions in NVAF. Identification of variables associated with dosing inconsistencies may enable targeted interventions to ensure label-consistent dosing in vulnerable populations.

Jitegemee (rely on yourself): a multi-phase process of co-creating a personal savings intervention with female sex workers in western Kenya to reduce their HIV risk

BackgroundHIV prevalence among female sex workers (FSW) is significantly higher than among women in the general population. Studies have shown that FSW engage in unprotected sex which provides higher compensation when they face emergency situations. We co-created a savings intervention – Jitegemee (rely on yourself) – with FSW to encourage them to save part of their earnings to withdraw in emergency situations in order to reduce risk.MethodsWe undertook a five-phase intervention development process between February 2021 and July 2023: 1) qualitative interviews with FSW to identify essential intervention features; 2) pilot trial to assess intervention feasibility; 3) literature review of studies on economic empowerment of FSW; 4) scoring of key components of Phases 1–3 on a scale of 1–5 (1 = definitely exclude, 5 = definitely include), for inclusion in the intervention package; 5) workshops with FSW and other key stakeholders to co-design the intervention.ResultsIn phase 1, nearly all participants (99%) found the intervention acceptable to them and 95% believed it would be acceptable to other FSW. Participants suggested inclusion of financial literacy (75%), savings groups (38%) and goal-setting (24%). In the feasibility assessment, 41% saved, of whom 46% withdrew some savings. Condom use was higher among FSW who withdrew their savings compared to those who did not (χ2 7.52; p = 0.006). In Phase 3, we identified 14 intervention components. In phase 4, all suggested intervention components scored 4.5 on average. In phase 5, we held 3 workshops with FSW to co-design the intervention, which included instructions for how to save and make withdrawals, financial literacy training, and formation of savings groups.ConclusionsA savings intervention for and by FSW was highly acceptable and feasible. Involving end-users in the design process is likely to result in greater economic security among FSW and lower engagement in higher risk transactional sex.

Triad of female athletes

The female sports triad is a spectrum of dysfunctions related to energy availability, menstrual function, and bone mineral density. Energy availability is considered the trigger for the triad. Scientists have proven that women who do sports consume approximately 30% less energy and carbohydrates in relation to their body weight. Sufficient energy availability ensures the presence of a menstrual cycle, directly affects the stimulation of the production of female sex hormones (estrogen in particular). Thus, it prevents resorption of bone tissue. When energy availability is too low, a physiological mechanism reduces the amount of energy used for cell maintenance, thermoregulation, growth, and reproductive function. This compensation tends to restore energy balance and promotes survival, but impairs health. Low body weight in women of reproductive age, particularly in adolescence and the first reproductive age, is a biological marker of somatic and reproductive dysfunction. Osteoporosis in young female athletes is manifested by fractures unusual for young women or by frequent and multiple bone fractures during an athletic career. In this review article, an analytical review of literary and informational sources regarding the history of research on the problem of the triad of female athletes is carried out. The specifics of the negative impact of the athlete triad on the female body, the components of the athlete triad (amenorrhea, eating disorders, and osteoporosis) are examined in detail. The article focuses on its main cause - energy imbalance. The impact of the triad of female athletes on the psyche and behavior is considered. The question of its consequences for health both in the short-term and in the long-term perspective is considered. The prevention of RED-S syndrome was also investigated. The purpose of the study: Systematization of current knowledge about the triad of female athletes (relative energy deficiency syndrome (RED-S)). Research methods. Theoretical analysis of literary sources, systematization, generalization of scientific-methodical and special literature.

Barriers and facilitators to cervical cancer screening among under- and neverscreened women in Flanders, Belgium – a qualitative study on community and healthcare providers’ perspectives

BackgroundCervical cancer is detectable and preventable in premalignant stages. In 2013, a population-based cervical cancer screening (CCS) programme was set up in Flanders (Belgium) promoting screening by means of sending reminder letters. Yet, in 2021, only a CCS coverage of 63.6% has been reached, which is just a bare increase since the implementation of the programme (62.7% in 2013) (Jaarrapport 2022, Centrum voor Kankeropsporing (CvKO), 2022; Jaarrapport 2015, Centrum voor Kankeropsporing (CvKO), 2015).ObjectivesTo explore the characteristics of under- and neverscreened women in Flanders and to gain a better understanding of the barriers that prevent these women from attending CCS as well as factors that may facilitate CCS uptake.MethodsTwelve in-depth interviews and six focus group discussions were conducted with gynaecologists, general practitioners, community health workers and stakeholders providing support to women belonging to potentially underscreened population groups. Reported barriers and facilitators were subsequently classified using the Socio-Ecological Model (SEM). Finally, a causal loop diagram was constructed to visualise the dynamic interrelations among the barriers and facilitators.ResultsStakeholders and healthcare professionals confirm the vulnerability for cervical cancer screening in women with a substance use disorder and women with a migration background. The participation in screening among female sex workers is contingent upon their specific work environment. The group of never- or underscreened women is very heterogeneous and includes many women who are either unaware of CCS or have other priorities. A lack of focus on prevention is the most commonly reported barrier at the healthcare system level. Increasing awareness about cervical cancer (screening) and creating more opportunities for healthcare workers to offer prevention services are the primary facilitators.ConclusionTo improve screening participation in Flanders, different screening strategies tailored to a diversity of women are needed.

Incidence, outcomes, and risk factors of postlaparoscopic subcutaneous emphysema: a historical cohort study.

Subcutaneous emphysema is a common complication of laparoscopic surgery. We aimed to determine the incidence, outcomes, and risk factors of postlaparoscopic subcutaneous emphysema. We conducted a single-centre historical cohort study of adult patients who underwent laparoscopic surgery at Kagoshima University Hospital between 1 April 2018 and 31 March 2021. We used multivariable logistic regression analysis to identify independent factors associated with postlaparoscopic subcutaneous emphysema. We included 1,642 patients with a median [interquartile range] age of 65 [53-72] yr. Postlaparoscopic subcutaneous emphysema was diagnosed in 600 (37%) patients. Female sex (odds ratio [OR], 1.82; 99.5% confidence interval [CI], 1.29 to 2.58), peak end-tidal carbon dioxide ≥ 45mm Hg (OR, 2.07; 99.5% CI, 1.43 to2.98), and use of the AirSeal® Intelligent Flow System (CONMED Corp., Largo, FL, USA) (OR, 3.37; 99.5% CI, 2.34 to 4.87) were independent factors associated with postlaparoscopic subcutaneous emphysema. In addition, a lower body mass index was significantly associated with increased postlaparoscopic subcutaneous emphysema (P for trend < 0.001). No complications were associated with postlaparoscopic subcutaneous emphysema. This historical cohort study showed a relatively high incidence of postlaparoscopic subcutaneous emphysema. In addition to previously reported risk factors, female sex and use of the AirSeal Intelligent Flow System were found to be associated with postlaparoscopic subcutaneous emphysema.

Use of Complementary and Integrative Health Approaches in Adults with Long COVID in the US, a Nationally Representative Survey.

Background: Long COVID is a serious, complex condition that has affected the lives of millions of people globally. Complementary and integrative health (CIH) approaches offer a wide range of potential therapies for the management of long COVID symptoms. However, there is limited information available about the utilization of CIH among long COVID patients. Methods: Nationally representative cross-sectional data from the United States 2022 National Health Interview Survey (NHIS, response rate 47.7%, n = 27,651) were used to investigate prevalence and predictors of CIH use in the past 12 months among individuals who experienced long COVID. The 12-month prevalence of CIH use was descriptively analyzed for those with long COVID versus those without using chi-squared tests or unpaired t-tests. Independent predictors of CIH use among individuals with long COVID were analyzed using a stepwise multiple logistic regression analysis. Results: A weighted total of 17,610,801 US adults (19.7%) who had a confirmed case of coronavirus disease 2019 (COVID-19) developed long COVID symptoms. A slightly greater proportion of individuals with long COVID (44.4%) than those without (40.9%) used CIH approaches in the past 12 months. The most used approaches were meditation, yoga, and massage therapy. CIH use by those with long COVID was significantly associated with younger age, female sex, higher education level, having health insurance coverage, higher household income level, receiving three or more COVID-19 vaccination doses, ever having asthma, and ever having an anxiety or depression diagnosis. Conclusions: Long COVID represents a major challenge for patients, health care providers, health care systems, economies, and global public health. CIH approaches may play an important role in symptom management for some patients, and additional research is needed to identify which modalities are most effective. Patients and health care providers may benefit from better information about the available options for treatment.

Risk factors analysis and nomogram conduction for major adverse events after lumbar fusion surgery in older patients: a prospective cohort study

This study aimed to identify risk factors for major adverse events (AEs) after lumbar fusion surgery in patients aged 75 and over and evaluate the role of several common geriatric comprehensive assessment items in predicting postoperative major AEs. This is a prospective cohort study of patients aged ≥75 years who underwent open lumbar fusion for degenerative spine disease from August 2019 to August 2022. The primary outcome measure was the incidence of major postoperative AEs within 90 days after surgery. Clavien-Dindo III-IV complications and unplanned readmission were defined as major AEs. Patients' characteristics, laboratory tests, assessment results, and surgery-related variables were compared between the major AEs and the non-major AEs groups. Multivariable logistic regression analysis was used to identify independent risk factors for major AEs. The logistic regression model was evaluated in another prospective cohort of patients from October 2022 to October 2023. A total of 301 patients (mean [SD] age, 79.7 [3.5] years; 60.5% male) were included in the study. Five features, including female (OR 1.99, p = 0.040), higher body mass index (BMI) (OR 1.090, p = 0.024), frailty (OR 2.043, p = 0.032), hypoalbuminemia (OR 2.489, p = 0.040), and higher Charlson comorbidity index (CCI) (OR 1.397, p = 0.024), were independently associated with major AEs and were selected to develop a predictive nomogram of major AEs. The area under the curve values for the development set and validation set were 0.75 and 0.71, respectively. Preoperative frailty, hypoalbuminemia, female sex, greater BMI, and higher CCI grade were risk factors for 90-day major AEs after lumbar fusion surgery in older patients. The predictive nomogram that we developed using this data can enhance preoperative risk counseling and optimization for older patients.

Baseline characteristics and associated factors for hypertension in children with chronic kidney disease: results from the Korean Cohort Study for Outcome in Patients with Pediatric Chronic Kidney Disease study.

Hypertension is one of the most important complications of chronic kidney disease (CKD) as it exacerbates disease progression in children. The aim of this study is to identify characteristics and factors associated with hypertension in children with CKD. This is a cross-sectional study using baseline data from the 10-year ongoing cohort study named KNOW-PedCKD (Korean Cohort Study for Outcome in Patients with Pediatric Chronic Kidney Disease). We enrolled finally 378 patients aged <18 years at seven major pediatric nephrology centers in Republic of Korea. Blood pressure was measured and samples and clinical data were collected during the patients' annual hospital visits. We found that 30.7% of the patients had hypertension (n = 116); specifically, 16.4% (n = 62) had systolic hypertension, and 22.8% (n = 86) had diastolic hypertension. Multiple logistic regression analysis indicated that older age (odds ratio [OR], 1.13; p < 0.001), female sex (OR, 2.32; p = 0.002), a high left ventricular mass index (OR, 1.05; p < 0.001), and a high urine protein/creatinine ratio (OR, 1.12; p = 0.02) were significant associated factors for systolic or diastolic hypertension. This study analyzed the associated factors for hypertension in children with CKD. Hypertension is associated with various factors, including age, sex, heart status, and proteinuria. Therefore, clinicians should consider these factors during patient evaluations to improve health outcomes.

Impact of biological sex on heart transplant patients admitted to cardiac rehabilitation: A 10-year retrospective cohort study

IntroductionHeart transplantation (HTx) serves as the gold-standard therapy for end-stage heart failure, yet patients often experience physical deconditioning and cognitive impairments post-surgery. Cardiac rehabilitation (CR) has shown promise in the HTx context. However, uncertainty surrounds the impact of biological sex. Accordingly, the aim of this paper was to investigate the impact of biological sex in a cohort of patients with HTx early admitted to a residential CR program. MethodsThis was a retrospective analysis involving patients who underwent HTx at Niguarda Hospital and who subsequently participated in a CR program at IRCCS Fondazione Don Gnocchi, Milan, Italy, between 2010 and 2022. The primary endpoint was time to event (in months), with an event defined as a composite outcome of whichever occurred first of death, allograft rejection, or cardiac allograft vasculopathy up to 30 months follow-up. ResultsIn a total of 129 patients, 60 % male, and 40 % female, baseline characteristics presented comparably between the sexes. At 6 months, no significant sex differences were observed for the primary composite outcome. However, at 30 months, females exhibited a significantly lower incidence of the primary composite outcome and an increased survival rate. Multivariable analysis confirmed a protective effect of female sex against mortality (F vs. M, HR 0.164, 95 % CI 0.038–0.716, P = 0.0161). ConclusionsDespite limitations, our findings emphasize that sex affects post-HTx long-term follow-up following CR discharge, with more favorable outcomes for female recipients. In an era of tailored management algorithms, it is imperative to take into account the gender gap even in cardiac rehabilitation.

A Comparison of 226- and 1000-Hz Probe Tone Tympanometry With Myringotomy Findings in Infants.

This study aimed to verify the diagnostic value of tympanometry with 226- and 1000-Hz probe tones in infants by comparing tympanometry results with the gold standard of the middle ear state assessed by myringotomy. Furthermore, clinically useful predictors for false peaked tympanograms despite the presence of middle ear fluid should be identified. Pre-operative 226- and 1000-Hz tympanograms were retrospectively compared with intraoperative findings of the tympanic cavity after myringotomy in 111 infants (217 ears) aged ≤ 12 months. In addition to the shape of tympanograms, demographic and clinical characteristics, the results of other audiometric measurements, and the viscosity of middle ear fluid, if present, were evaluated in several subgroups. The sensitivity and specificity of 1000-Hz tympanometry for middle ear effusion (MEE) detection were 97%-98% and 71%-84%, respectively, whereas standard tympanometry with a 226-Hz probe tone achieved a poor sensitivity of 43%-61% and a specificity of 81%-97%. Younger age, low viscosity of the middle ear fluid, and female sex were associated with an increased risk of false peaked 226-Hz tympanograms despite MEE. Furthermore, larger equivalent outer ear canal volumes were linked to false peaked 226-Hz tympanograms. The comparison of myringotomy findings and 226- and 1000-Hz tympanometry confirms the superiority of high-frequency tympanometry in infants younger than 12 months. Although this study identified some vague predictors of potentially false peaked 226-Hz tympanograms, the assessment of the middle ear state by 226-Hz tympanometry remains unreliable in young infants.
