#59 Fibroblast Growth factor 23 for prediction of outcome in community-acquired acute kidney injury: a prospective observational study

Abstract Background and Aims Serum FGF23 level has been found to be elevated in AKI through multiple previous studies. Moreover, higher FGF23 level was associated with mortality and adverse outcomes in critically ill patients and patients undergoing cardiac surgery who developed AKI suggesting that FGF23 can have a prognostic value in AKI. The current study aims to investigate the association of serum FGF23 levels with morbidity and mortality in patients with community-acquired AKI. Method A longitudinal prospective study was carried out that included 64 patients who presented with community-acquired AKI to Mansoura Nephrology and Dialysis Unit (MNDU) at Mansoura University Hospital. Serum intact FGF23 level was measured after admission. patients were followed up during hospital stay and then at 90-day after admission. The primary outcomes were hospital and 90-day mortality and renal recovery. Results In this study, nine of the studied 64 AKI patients (14.1%) died during hospital admission and 18 out of 62 AKI patients (29%) died during the 90-day follow up period including those who died during hospital admission. Hospital mortality was significantly higher in patients with shock, sepsis, hypoalbuminemia, or high FGF23 in univariate analysis (p < 0.05). However, when binary logistic regression was carried out, shock was the only significant independent predictor for mortality [p value = 0.015; adjusted odds ratio = 12.465], while serum FGF23 did not independently predict in-hospital [p value = 0.589; adjusted odds ratio = 1.001] or 90-day mortality [p value = 0.055; adjusted odds ratio = 1.003] when entered in the regression equation together with the other confounders. Serum FGF23 in this study was not also associated with renal recovery, need for renal replacement, or the duration from peak serum creatinine to renal recovery (p > 0.05). Conclusion This research showed that serum iFGF23 could not predict mortality, renal recovery, or need for renal replacement therapy in patients with community-acquired AKI.

Association between heme oxygenase-1 and hyperlipidemia in pre-diabetic patients: a cross-sectional study

BackgroundAlthough the importance and benefit of heme oxygenase-1 (HO-1) in diabetes rodent models has been known, the contribution of HO-1 in the pre-diabetic patients with hyperlipidemia risk still remains unclear. This cross-sectional study aims to evaluate whether HO-1 is associated with hyperlipidemia in pre-diabetes.MethodsSerum level of HO-1 was detected using commercially available ELISA kit among 1,425 participants aged 49.3–63.9 with pre-diabetes in a multicenter Risk Evaluation of cAncers in Chinese diabeTic Individuals: A lONgitudinal (REACTION) prospective observational study. Levels of total cholesterol (TC) and triglyceride (TG) were measured and used to defined hyperlipidemia. The association between HO-1 and hyperlipidemia was explored in different subgroups.ResultThe level of HO-1 in pre-diabetic patients with hyperlipidemia (181.72 ± 309.57 pg/ml) was obviously lower than that in pre-diabetic patients without hyperlipidemia (322.95 ± 456.37 pg/ml). High level of HO-1 [(210.18,1,746.18) pg/ml] was negatively associated with hyperlipidemia (OR, 0.60; 95% CI, 0.37–0.97; p = 0.0367) after we adjusted potential confounding factors. In subgroup analysis, high level of HO-1 was negatively associated with hyperlipidemia in overweight pre-diabetic patients (OR, 0.50; 95% CI, 0.3–0.9; p = 0.034), especially in overweight women (OR, 0.42; 95% CI, 0.21–0.84; p = 0.014).ConclusionsIn conclusion, elevated HO-1 level was negatively associated with risk of hyperlipidemia in overweight pre-diabetic patients, especially in female ones. Our findings provide information on the exploratory study of the mechanism of HO-1 in hyperlipidemia, while also suggesting that its mechanism may be influenced by body weight and gender.

Outcome of antiemetic prophylaxis among pediatric cancer patients receiving moderate to highly emetogenic chemotherapy at pediatric hemato-oncology ward of Tikur Anbessa specialized hospital: A prospective observational study.

Chemotherapy-induced nausea and vomiting (CINV) is a major issue for chemotherapy pediatric patients, especially in developing countries due to limited access to essential antiemetics. This study aimed to assess antiemetic prophylaxis outcomes in pediatric cancer patients at Tikur Anbessa Specialized Hospital in Addis Ababa, Ethiopia. A longitudinal prospective observational study design was conducted among 201 pediatric cancer patients followed up to 120 h post-chemotherapy. The majority of patients (75.1%) received combination prophylactic antiemetics in the acute phase. Complete response (CR) was the highest in the acute phase (71.1%). Emesis episodes occurred most frequently on the first day of treatment (28.4%) and gradually decreased over time. History of motion sickness, platinum-based chemotherapy, and prior chemotherapy-induced vomiting (CIV) were associated with emesis during the acute phase whereas multiple-day chemotherapy, prior CIV, receipt of antiemetics, and a history of motion sickness in the delayed phase. However, the odds of CIV were reduced with steroid presence in the chemotherapy regimen. A considerable number of participants could not achieve a CR. It is important for clinicians to be cognizant of risk factors that influence the outcome of antiemetic prophylaxis to achieve better control of CINV among pediatric cancer patients.

Psychological Predictors of Mental Health Difficulties after Pediatric Concussion.

Children often experience mental health difficulties after a concussion. Yet, the extent to which a concussion precipitates or exacerbates mental health difficulties remains unclear. This study aimed to examine psychological predictors of mental health difficulties after pediatric concussion. Children (aged 5 to <18 years, M=11.7, SD=3.3) with concussion were recruited in a single-site longitudinal prospective cohort study conducted at a tertiary children's hospital (n=115, 73.9% male). The primary outcomes included internalizing (anxious, depressed, withdrawn behaviors), externalizing (risk-taking, aggression, attention difficulties), and total mental health problems, as measured by the Child Behavior Checklist at two weeks (acute) and three months (post-acute) after concussion. Predictors included parents' retrospective reports of premorbid concussive symptoms (Post-Concussion Symptom Inventory; PCSI), the child and their family's psychiatric history, child-rated perfectionism (Adaptive-Maladaptive Perfectionism Scale), and child-rated resilience (Youth Resilience Measure). Higher premorbid PCSI ratings consistently predicted acute and post-acute mental health difficulties. This relationship was significantly moderated by child psychiatric history. Furthermore, pre-injury learning difficulties, child psychiatric diagnoses, family psychiatric history, lower resilience, previous concussions, female sex, and older age at injury were associated with greater mental health difficulties after concussion. Pre-injury factors accounted for 23.4-39.9% of acute mental health outcomes, and 32.3-37.8% of post-acute mental health outcomes. When acute mental health was factored into the model, a total of 47.0%-68.8% of variance was explained by the model. Overall, in this sample of children, several pre-injury demographic and psychological factors were observed to predict mental health difficulties after a concussion. These findings need to be validated in future research involving larger, multi-site studies that include a broader cohort of children after concussion.

Effects of Continuous Dopaminergic Stimulation on Parkinson's Disease Gait: A Longitudinal Prospective Study with Levodopa Intestinal Gel Infusion.

Gait issues, including reduced speed, stride length and freezing of gait (FoG), are disabling in advanced phases of Parkinson's disease (PD), and their treatment is challenging. Levodopa/carbidopa intestinal gel (LCIG) can improve these symptoms in PD patients with suboptimal control of motor fluctuations, but it is unclear if continuous dopaminergic stimulation can further improve gait issues, independently from reducing Off-time. To analyze before (T0) and after 3 (T1) and 6 (T2) months of LCIG initiation: a) the objective improvement of gait and balance; b) the improvement of FoG severity; c) the improvement of motor complications and their correlation with changes in gait parameters and FoG severity. This prospective, longitudinal 6-months study analyzed quantitative gait parameters using wearable inertial sensors, FoG with the New Freezing of Gait Questionnaire (NFoG-Q), and motor complications, as per the MDS-UPDRS part IV scores. Gait speed and stride length increased and duration of Timed up and Go and of sit-to-stand transition was significantly reduced comparing T0 with T2, but not between T0-T1. NFoG-Q score decreased significantly from 19.3±4.6 (T0) to 11.8±7.9 (T1) and 8.4±7.6 (T2) (T1-T0 p = 0.018; T2-T0 p < 0.001). Improvement of MDS-UPDRS-IV (T0-T2, p = 0.002, T0-T1 p = 0.024) was not correlated with improvement of gait parameters and NFoG-Q from T0 to T2. LEDD did not change significantly after LCIG initiation. Continuous dopaminergic stimulation provided by LCIG infusion progressively ameliorates gait and alleviates FoG in PD patients over time, independently from improvement of motor fluctuations and without increase of daily dosage of dopaminergic therapy.

Urinary sFlt-1 and PlGF as preeclampsia predictors: sFlt-1/creatinine ratio improves the prediction value

ObjectivesTo evaluate the correlation between maternal serum and urinary soluble Fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) levels and to assess their potential value in preeclampsia and fetal growth restriction. Study DesignThis case-control longitudinal prospective study was performed in 49 singleton pregnant women, divided into two clinical groups, low risk pregnancy (n = 23) and pregnancy complicated by preeclampsia (n = 26). Maternal serum and urinary sFlt-1 and PlGF levels were quantified by electrochemiluminescence. Every patient underwent an ultrasound for fetal biometry. Doppler assessment was done when estimated fetal weight was under the 10th centile. ROC curves were used to evaluate the predictive capability of serum and urinary angiogenic biomarkers and their ratios on preeclampsia. Linear regression was used to compare the values of serum and urinary sFlt-1 and PlGF and their ratios. ResultsUrine biomarkers were positively associated with their serum values, being the best associated urinary PlGF (R2 = 0.73), which also showed the highest predictive capability of preeclampsia of urine biomarkers (AUC 0.866). The predictive capability of urinary sFlt-1 was much lower (AUC 0.640), but increased when adjusting by serum creatinine, a more precise parameter (AUC 0.863). ConclusionsUrinary PlGF could be a lesser invasive alternative to circulating biomarkers to monitor pregnancies complicated with preeclampsia that need repeated controls of their pregnancy complication. Urinary sFlt-1 values need adjustment by serum creatinine to be reliable.

The Chinese keratoconus (CKC) cohort study.

The Chinese keratoconus (CKC) cohort study is a population-based longitudinal prospective cohort study in the Chinese population involving a clinical database and biobanks. This ongoing study focuses on the prevention of KC progression and is the first to involve the effect of gene‒environment interactions on KC progression. The CKC cohort is hospital-based and dynamic and was established in Zhengzhou, China; KC patients (n = 1114) from a large geographical area were enrolled from January 2019 to June 2023, with a mean age of 22.23 years (6‒57 years). Demographic details, socioeconomic characteristics, lifestyle, disease history, surgical history, family history, and visual and social function data are being collected using questionnaires. General physical examination, eye examination, biological specimen collection, and first-degree relative data were collected and analyzed in the present study. The primary focus of the present study was placed on gene, environment and the effect of gene‒environment interactions on KC progression. The follow-up of the CKC cohort study is expected to include data collection at 3 months, 6 months, and 1 year after the initial examination and then at the annual follow-up examinations. The first follow-up of the CKC cohort study was recorded. A total of 918 patients completed the follow-up by June 1, 2023, with a response rate of 82.40%. Aside from the younger age of patients who were followed up, no significant differences were found between patients who were followed up and patients who were not.

Oral health-related quality of life in implant-supported rehabilitations: a prospective single-center observational cohort study

BackgroundOral Health-Related Quality of Life (OHRQoL) is a comprehensive concept covering daily comfort, self-esteem, and satisfaction with oral health, including functional, psychological, and social aspects, as well as pain experiences. Despite abundant research on OHRQoL related to oral diseases and hygiene, there is limited data on how patients perceive changes after implant-prosthetic rehabilitation. This study aimed to evaluate OHRQoL and aesthetic perception using OHIP-14 and VAS scales respectively, before (baseline-TB), during (provisional prostheses-TP), and after (definitive prostheses-TD) implant-prosthetic rehabilitation. It also explored the impact of biological sex, substitution numbers, and aesthetic interventions on OHRQoL and VAS scores, along with changes in OHIP-14 domains.MethodsA longitudinal prospective single-center observational cohort study was conducted with patients requiring implant-prosthetic rehabilitation. Quality of life relating to dental implants was assessed through the Italian version of Oral Health Impact Profile-14 (IOHIP-14), which has a summary score from 14 to 70. Patients’ perceived aesthetic was analyzed through a VAS scale from 0 to 100. Generalized Linear Mixed Effect Models, Linear Mixed Effect Models, and Friedman test analyzed patient responses.Results99 patients (35 males, 64 females) aged 61–74, receiving various prosthetic interventions, were enrolled. Both provisional and definitive prosthetic interventions significantly decreased the odds of a worse quality of life compared to baseline, with odds ratios of 0.04 and 0.01 respectively. VAS scores increased significantly after both interventions, with estimated increases of 30.44 and 51.97 points respectively. Patient-level variability was notable, with an Intraclass Correlation Coefficient (ICC) of 0.43. While biological sex, substitution numbers, and aesthetic interventions didn’t significantly affect VAS scores, OHRQoL domains showed significant changes post-intervention.ConclusionsThese findings support the effectiveness of implant-prosthetic interventions in improving the quality of life and perceived aesthetics of patients undergoing oral rehabilitation. They have important implications for clinical practice, highlighting the importance of individualized treatment approaches to optimize patient outcomes and satisfaction in oral health care.

Abstract PO4-03-09: Profile of circulating natural killer cells in stage III triple negative breast cancer before and after neoadjuvant chemotherapy

Abstract Background: Triple negative breast cancer (TNBC) is the most aggressive subtype of breast cancer. The treatment for locally advanced disease is based on neoadjuvant chemotherapy and immunotherapy, with complete pathological response (pCR) serving as a predictor of disease-free survival. Although the presence of immune cell infiltration in the tumor has a favorable prognostic impact, there is a lack of predictive biomarkers for complete pathological response to neoadjuvant chemotherapy (NAC). Objective: to analyze the profile of circulating Natural Killer (NK) cells and NK subpopulations (NK FAS+ and NK PD1+) in association with the occurrence of complete pathological response after neoadjuvant chemotherapy in women with clinical stage III TNBC. Methods: This was a longitudinal prospective and translational cohort study, including women aged 18 to 60 years with stage III TNBC diagnosed between March 2015 and July 2017, with a follow-up of 24 months. A comparison control group consisted of 30 healthy women aged 18 to 60 years without prior or current cancer diagnosis and no family history of breast cancer. Peripheral blood samples were collected before NAC and before surgery. Flow cytometry was used to analyze the percentage levels of NK cells and NK subpopulations (NK FAS+ and NK PD1+). The Shapiro-Wilk test was initially applied to assess the normality of quantitative variables. The non-parametric Mann-Whitney test was used for comparison between two groups. The statistical significance level was set at p&amp;lt; 0.05. Overall survival (OS) was estimated using the Kaplan-Meier method. Statistical analysis was performed using GraphPad Prism v9.5.1. Results: The median age was 45 years. Stage IIIA was identified in 28% of the patients, while IIIB was observed in 72%. Regarding pathological response, 14 patients (48%) achieved pCR, while 15 patients (52%) had a non-complete pathological response (non-pCR). The 2-year OS was 86%, with no median reached. Higher percentage levels of NK cells, NK FAS+, and NK PD1+ were observed in the patient group compared to the control group, with significant differences. There was a significant increase in the percentage levels of NK cells after NAC compared to pre-NAC levels, and a reduction in NK PD1+ levels. NK cell levels were significantly higher in patients with stage IIIA compared to stage IIIB, while NK FAS+ levels were lower. NK cell and NK FAS+ subpopulation levels were significantly higher in patients who achieved pCR compared to non-pCR patients, with no difference in NK PD1+ cell levels. Conclusions: Elevated levels of circulating NK cells and NK FAS+ subpopulation collected from peripheral blood before NAC may serve as potential biomarkers for pCR in patients with TNBC.

Phosphorylated neurofilament heavy chain in cerebrospinal fluid and plasma as a Nusinersen treatment response marker in childhood-onset SMA individuals from Serbia.

Biomarkers capable of reflecting disease onset and short- and long-term therapeutic effects in individuals with spinal muscular atrophy (SMA) are still an unmet need and phosphorylated neurofilament heavy chain (pNF-H) holds significant promise. We conducted a longitudinal prospective study to evaluate pNF-H levels in the cerebrospinal fluid (CSF) and plasma of 29 individuals with childhood-onset SMA treated with Nuinersen (SMA type 1: n = 6, 2: n = 17, 3: n = 6). pNF-H levels before and during treatment were compared with the levels of controls (n = 22), patients with Duchenne muscular dystrophy (n = 17), myotonic dystrophy type 1 (n = 11), untreated SMA individuals with chronic type 3 disease (n = 8), and children with presymptomatic SMA (n = 3). SMA type 1 showed the highest mean CSF pNF-H levels before treatment initiation. All Nusinersen-treated individuals (types 1, 2, and 3) showed significantly elevated mean baseline CSF pNF-H compared to controls, which inversely correlated with age at disease onset, age at first dose, disease duration and the initial CHOP INTEND result (SMA type 1 and 2). During 22 months of treatment, CSF pNF-H levels declined during loading doses, stabilizing at reduced levels from the initial maintenance dose in all individuals. Baseline plasma pNF-H levels in type 1 and 2 SMA were significantly increased compared to other cohorts and decreased notably in type 1 after 2 months of treatment and type 2 after 14 months. Conversely, SMA type 3, characterized by lower baseline pNF-H levels, did not show significant fluctuations in plasma pNF-H levels after 14 months of treatment. Our findings suggest that CSF pNF-H levels in untreated SMA individuals are significantly higher than in controls and that monitoring of CSF pNF-H levels may serve as an indicator of rapid short-term treatment response in childhood-onset SMA individuals, irrespective of the subtype of the disease, while also suggesting its potential for assessing long-term suppression of neurodegeneration. Plasma pNF-H may serve as an appropriate outcome measure for disease progression and/or response to treatment in types 1 and 2 but not in type 3. Presymptomatic infants with SMA may show elevated pNF-H levels, confirming early neuronal degeneration.

Family Violence Against Children and Parents’ Social Support during the COVID-19 Pandemic: A Cohort Study

Amid the COVID-19 pandemic, several experts have raised concerns over an increased risk of family violence. The proximity between confined family members and social isolation fostered tensions, making families more vulnerable. The first objective of this study was to describe the evolution of family violence against children (psychological aggression and corporal punishment) and parents' social support during the COVID-19 pandemic. The second objective was to determine the contribution of parents’ social support to the evolution of family violence against children between two measurement times. Participants included parents living with at least one child between 0 and 17 years old (N = 514) from the broader longitudinal prospective cohort study, My Life and the Pandemic in Quebec (MAVIPAN) from Quebec, Canada. Family violence against children and social support were measured twice (2020 and 2021) with a web-based survey. Most parents reported no family violence against children. Psychological aggression significantly decreased between the two measurement times (p = .003). Corporal punishment and social support remained stable. Social support was a significant predictor of the evolution of psychological aggression. Participants reporting a lower level of perceived social support at baseline were more likely to report psychological aggression at both measurement times, compared to the reference group of parents reporting none (p = .002; OR = 0.914). Social support emerged as a protective factor when psychological aggression towards children is chronic in a family. This study contributes to the growing literature documenting the experience of parents during the COVID-19 pandemic.

Cognitive Function, Healthy Lifestyle, and All-Cause Mortality among Chinese Older Adults: A Longitudinal Prospective Study.

Both cognitive decline and unhealthy lifestyles have been linked to an elevated risk of mortality in older people. We aimed to investigate whether a healthy lifestyle might modify the association between cognitive function and all-cause mortality in Chinese older populations. The final analysis included 5124 individuals free of dementia, selected from the Chinese Longitudinal Healthy Longevity Survey from 2011 to 2018. Cognitive function was assessed in 2011 using the Mini-Mental State Examination (MMSE). A lifestyle score was calculated based on five lifestyle factors, including smoking, alcohol consumption, physical activity, diet, and body mass index. Cox proportional hazards models were performed to evaluate the association between baseline cognitive function and the risk of all-cause mortality, with an interaction term of cognitive function and lifestyle score being added to the models. The average age of participants was 81.87 years old at baseline. During a median follow-up of 6.4 years, 1461 deaths were documented. Both higher cognitive function (HR: 0.96; 95% CI: 0.96-0.97) and a healthier lifestyle (HR: 0.92; 95% CI: 0.87-0.97) were significantly associated with a reduced risk of mortality. We found that lifestyle significantly modified the association of cognitive function with mortality (p for interaction = 0.004). The inverse relation between cognitive function and mortality was found to be more pronounced among participants with a healthier lifestyle. Of note, among the lifestyle scores component, diet showed a significant interaction with mortality (p for interaction = 0.003), and the protective HR of the all-cause mortality associated with higher MMSE scores was more prominent among participants with healthy diets compared with unhealthy diets. Our study indicates that cognitive decline is associated with a higher risk of mortality, and such associations are attenuated by maintaining a healthy lifestyle, with a particular emphasis on healthy diet.

Does pain intensity after total knee arthroplasty depend on somatosensory functioning in knee osteoarthritis patients? A prospective cohort study

The objective of this study is to determine whether the change in pain intensity over time differs between somatosensory functioning evolution profiles in knee osteoarthritis (KOA) patients undergoing total knee arthroplasty (TKA). This longitudinal prospective cohort study, conducted between March 2018 and July 2023, included KOA patients undergoing TKA in four hospitals in Belgium and the Netherlands. The evolution of the Knee Injury and Osteoarthritis Outcome Score (KOOS) subscale pain over time (baseline, 3 months, and 1 year post-TKA scores) was the outcome variable. The evolution scores of quantitative sensory testing (QST) and Central Sensitization Inventory (CSI) over time (baseline and 1 year post-TKA scores) were used to make subgroups. Participants were divided into separate normal, recovered, and persistent disturbed somatosensory subgroups based on the CSI, local and widespread pressure pain threshold [PPT] and heat allodynia, temporal summation [TS], and conditioned pain modulation [CPM]. Linear mixed model analyses were performed. Two hundred twenty-three participants were included. The persistent disturbed somatosensory functioning group had less pronounced pain improvement (based on CSI and local heat allodynia) and worse pain scores 1 year post-TKA (based on CSI, local PPT and heat allodynia, and TS) compared to the normal somatosensory functioning group. This persistent group also had worse pain scores 1 year post-TKA compared to the recovered group (based on CSI). The study suggests the presence of a “centrally driven central sensitization” subgroup in KOA patients awaiting TKA in four of seven grouping variables, comprising their less pain improvement or worse pain score after TKA. Future research should validate these findings further. The protocol is registered at clinicaltrials.gov (NCT05380648).

Does a Healthy Weight Body Mass Index at Onset of Idiopathic Intracranial Hypertension Change the Outcomes? A United Kingdom Prospective Cohort Study

ABSTRACT Idiopathic intracranial hypertension (IIH) predominantly affects reproductive-aged females with obesity. However, the prevalence and impact of a healthy weight body mass index (BMI) at disease presentation is not known. This study aimed to evaluate the visual and headache outcomes stratified by the presenting BMI. This was a longitudinal prospective cohort study (IIH Life) based on a tertiary neuro-ophthalmology IIH service, University Hospitals Birmingham NHS Trust, United Kingdom, recruiting consecutive patients living with IIH between 2012 and 2021. Those with a presenting BMI were included. The outcome measures included visual outcomes of LogMAR visual acuity, Humphrey visual field perimetric mean deviation (PMD), optical coherence tomography (OCT) measurements, and headache outcomes of frequency, severity, and Headache Impact Test-6 score. Three hundred seventy-five people with IIH and a documented baseline BMI. About 3.7% of the entire cohort had a healthy weight BMI at IIH presentation and 15.5% BMI < 30 kg/m2. The baseline PMD was worse in patients without obesity; however, OCT papilloedema measures were similar. The presence of obesity was associated with a small but significant greater worsening in visual acuity but slower macular ganglion cell layer loss. There was no impact on PMD or papilloedema prognosis related to baseline obesity. The headache outcomes showed heterogeneity, with worse baseline headache frequency in patients with obesity. No BMI group was associated with worse headache outcomes. Patients with a healthy weight BMI or those without obesity at baseline make up a small proportion of IIH patients. BMI at presentation does not appear to influence long-term visual or headache outcomes.

Actigraphy measures show sleep improvement after parathyroidectomy for primary hyperparathyroidism

ImportanceThe symptoms of primary hyperparathyroidism are often subtle, such as fatigue, mood changes, and sleep disturbances. After parathyroidectomy, patients often report improvement in sleep and mood; however, objective data supporting these improvements is lacking. ObjectiveThis prospective study uses standard measures to objectively and subjectively assess sleep in patients with primary hyperparathyroidism before and after parathyroidectomy. DesignA longitudinal prospective study was conducted over three one-week-long periods: pre-parathyroidectomy, 1-week post-parathyroidectomy, and three months post-parathyroidectomy. During each time point, patients wore an actigraphy device, recorded a sleep diary, and completed the Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), and Depression Anxiety Stress Scale (DASS). Statistical analysis was performed using repeated measures models to compare the average measures among the three time points and test for trends over time. SettingSingle institution, tertiary care center. ParticipantsPatients with primary hyperparathyroidism from ages 18 to 89 years old. ExposureParathyroidectomy between September 2020 and January 2024. Main outcomes and measuresActigraphy data, consensus sleep diary, Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Depression Anxiety Stress Scales – 21 Items (DASS). ResultsThirty-six patients were enrolled, and 34 patients completed the study. Actigraphy data showed a significant negative trend in average sleep latency (p = 0.045) and average time in bed (p = 0.046). Sleep diary data showed additional differences in the number of awakenings (p = 0.002), wake after sleep onset (p < 0.001), sleep quality (p < 0.001), and sleep efficiency (p = 0.02) among the three time points and/or as a significant negative trend. PSQI and ISI scores were significantly different among the three time points (p = 0.002 and p < 0.001, respectively) and also declined significantly over time (p = 0.008 and p = 0.007, respectively). DASS depression, anxiety, and stress scores were significantly different among the three time points (p < 0.001, p = 0.01, and p < 0.001, respectively), and stress also declined significantly over time (p = 0.005). Conclusion and relevanceThis study represents the most extensive prospective study demonstrating objective and subjective sleep and mood improvement in patients with primary hyperparathyroidism after parathyroidectomy.

Using Odih-Score (Modified Klotz Score) for quality of defecation after anorectal malformation following posterior sagittal anorectoplasty (PSARP): Study of validation

Abstract* Objective The diagnostic scale or score is a clinical assessment tool used to determine diagnosis and evaluate further therapy results. The Klotz Score is a previous score modified to create a new instrument, the Odih-score. This new instrument is specifically designed to evaluate the quality of defecation success after operative anorectal malformation and is expected to be simpler and easier to apply in research hospitals. Its primary use is to evaluate the quality of defecation in post-PSARP anorectal malformation patients. Method The study conducted between 2016 and 2021, a longitudinal prospective study was conducted at RSUD Arifin Achmad Pekanbaru Riau Indonesia. The study aimed to validate the reliability of the Odih-Score (Modified Klotz Score) research instrument for evaluating defecation quality in post-PSARP anorectal malformation patients. Pearson validation test and Cronbach alpha reliability test were used as parameters for the validation, while the sensitivity and specificity of diagnostic tests were evaluated using research instrument (IBM SPSS Statistics version 25) The research was approved by the Ethical Clearance Board of the Faculty of Medicine, University of Riau, under reference number No.031/UN.19.5.1.1.8/UEPKK/2019. Results The analysis of the validation test results indicates that the Odih-Score is statistically significant (Sig.&lt;0.05) and has a greater r-count value (0.573-0.790) than the r-table value (0.202). The research reliability test also shows a high level of reliability (Cronbach alpha 0.814) for all five items of the Odih-Score instrument. Further, the sensitivity and specificity test as a diagnostic test resulted in an AUC value of 0.798, with an Odih-Score cut-off point of 11. Conclusion Odih-Score (Modified Klotz’s score) is considered valid and reliable and can be used as a diagnostic test instrument to evaluate the quality of post-anorectal Malformation defecation with PSARP.

Comparison of early patient-reported outcomes between uniportal thoracoscopic segmentectomy and wedge resection for peripheral small-sized non-small-cell lung cancer

BackgroundAnalysis of patient-reported outcomes (PROs) offers valuable insights into distinguishing the effects of closely related medical procedures from the patient’s perspective. In this study we compared symptom burden in patients undergoing uniportal thoracoscopic segmentectomy and wedge resection for peripheral small-sized non-small cell lung cancer (NSCLC).MethodsThis study included patients with peripheral NSCLC from an ongoing longitudinal prospective cohort study (CN-PRO-Lung 3) who underwent segmentectomy or wedge resection with tumor diameter ≤ 2 cm and consolidation tumor ratio (CTR) ≤ 0.5. PROs data were collected using the Perioperative Symptom Assessment for Lung Surgery questionnaire pre-operatively, daily post-surgery up to the fourth hospitalization day, and weekly post-discharge up to the fourth week. Propensity score matching and a generalized estimation equation model were employed to compare symptom severity. In addition, short-term clinical outcomes were compared.ResultsIn total, data of 286 patients (82.4%) undergoing segmentectomy and 61 patients (17.6%) undergoing wedge resection were extracted from the cohort. No statistically significant differences were found in the proportion of moderate-to-severe symptoms and mean scores for pain, cough, shortness of breath, disturbed sleep, fatigue, drowsiness, and distress during the 4-day postoperative hospitalization or the 4-week post-discharge period before or after matching (all p > 0.05). Compared with segmentectomy, wedge resection showed better short-term clinical outcomes, including shorter operative time (p = 0.001), less intraoperative bleeding (p = 0.046), and lower total hospital costs (p = 0.002).ConclusionsThe study findings indicate that uniportal thoracoscopic segmentectomy and wedge resection exert similar early postoperative symptom burden in patients with peripheral NSCLC (tumor diameter ≤ 2 cm and CTR ≤ 0.5).Clinical trial registrationNot applicable.
