Practicality of multilayer round window reinforcement in the surgical management of superior semicircular canal dehiscence syndrome: a case report of long-term follow-up.

Several surgical techniques have been documented for approaching and repairing superior semicircular canal dehiscence syndrome (SCDS). These techniques encompass the trans-middle cranial fossa, transmastoid, endoscopic approaches, and round window reinforcement (RWR). RWR entails the placement of connective tissue with or without cartilage and around the round window niche, restricting the round window's movement to minimize the 3rd window effect and restore the bony labyrinth closer to its normal state. We employed the multilayer RWR technique, resulting in significant postoperative improvement and long-lasting effects for 3.7 years in 2 cases. Here, we present the clinical findings, surgical procedures, and the effectiveness of multilayer RWR. This technique can be the initial choice for surgical treatments of SCDS due to its high effectiveness, longer-lasting effect, and minimal risk of surgical complications.

Vitamin D deficiency and effect of treatment on seizure frequency and quality of life parameters in patients with drug-resistant epilepsy: A randomized clinical trial.

OBJECTIVE: This study was undertaken to assess the effect of treatment of vitamin D deficiency in drug-resistant epilepsy. METHODS: We conducted a multicenter, double-blind, placebo-controlled, randomized clinical trial, including patients aged ≥15 years with drug-resistant focal or generalized epilepsy. Patients with 25-hydroxyvitamin D (25[OH]D) < 30 ng/mL were randomized to an experimental group (EG) receiving vitamin D3 (cholecalciferol, 100 000 IU, five doses in 3 months) or a control group (CG) receiving matched placebo. During the open-label study, EG patients received 100 000 IU/month for 6 months, whereas CG patients received five doses in 3 months then 1/month for 3 months. Monitoring included seizure frequency (SF), 25(OH)D, calcium, albumin, creatinine assays, and standardized scales for fatigue, anxiety-depression, and quality of life (Modified Fatigue Impact Scale [M-FIS], Hospital Anxiety and Depression Scale, Quality of Life in Epilepsy [QOLIE-31]) at 3, 6, and 12 months. The primary efficacy outcome was the percentage of SF reduction compared to the reference period and CG at 3 months. Secondary outcomes were SF and bilateral tonic-clonic seizure (BTCS) reduction, scale score changes, and correlations with 25(OH)D during the follow-up. RESULTS: Eighty-eight patients were enrolled in the study (56 females, aged 17-74 years), with median baseline SF per 3 months = 16.5 and ≥2 antiseizure medications in 88.6%. In 75 patients (85%), 25(OH)D was <30 ng/mL; 40 of them were randomly assigned to EG and 34 to CG. After the 3-month blinded period, SF reduction did not significantly differ between groups. However, during the open-label period, SF significantly decreased (30% median SF reduction, 33% responder rate at 12 months). BTCSs were reduced by 52%. M-FIS and QOLIE-31 scores were significantly improved at the whole group level. SF reduction correlated with 25(OH)D > 30 ng/mL for >6 months. SIGNIFICANCE: Despite no proven effect after the 3-month blinded period, the open-label study suggests that long-term vitamin D3 supplementation with optimal 25(OH)D may reduce SF and BTCSs, with a positive effect on fatigue and quality of life. These findings need to be confirmed by further long-term studies. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03475225 (03-22-2018).

Differential decline of SARS-CoV-2-specific antibody levels, innate and adaptive immune cells, and shift of Th1/inflammatory to Th2 serum cytokine levels long after first COVID-19.

BACKGROUND: SARS-CoV-2 has triggered a pandemic and contributes to long-lasting morbidity. Several studies have investigated immediate cellular and humoral immune responses during acute infection. However, little is known about long-term effects of COVID-19 on the immune system. METHODS: We performed a longitudinal investigation of cellular and humoral immune parameters in 106 non-vaccinated subjects ten weeks (10 w) and ten months (10 m) after their first SARS-CoV-2 infection. Peripheral blood immune cells were analyzed by multiparametric flow cytometry, serum cytokines were examined by multiplex technology. Antibodies specific for the Spike protein (S), the receptor-binding domain (RBD) and the nucleocapsid protein (NC) were determined. All parameters measured 10 w and 10 m after infection were compared with those of a matched, noninfected control group (n = 98). RESULTS: Whole blood flow cytometric analyses revealed that 10 m after COVID-19, convalescent patients compared to controls had reduced absolute granulocyte, monocyte, and lymphocyte counts, involving T, B, and NK cells, in particular CD3+CD45RA+CD62L+CD31+ recent thymic emigrant T cells and non-class-switched CD19+IgD+CD27+ memory B cells. Cellular changes were associated with a reversal from Th1- to Th2-dominated serum cytokine patterns. Strong declines of NC- and S-specific antibody levels were associated with younger age (by 10.3 years, p < .01) and fewer CD3-CD56+ NK and CD19+CD27+ B memory cells. Changes of T-cell subsets at 10 m such as normalization of effector and Treg numbers, decline of RTE, and increase of central memory T cell numbers were independent of antibody decline pattern. CONCLUSIONS: COVID-19 causes long-term reduction of innate and adaptive immune cells which is associated with a Th2 serum cytokine profile. This may provide an immunological mechanism for long-term sequelae after COVID-19.

Unraveling psilocybin's therapeutic potential: behavioral and neuroplasticity insights in Wistar-Kyoto and Wistar male rat models of treatment-resistant depression.

RATIONALE: Our study aimed to unravel the unknown mechanisms behind the exceptional efficacy of Psilocybin (PSI) in treating treatment-resistant depression (TRD). Focusing on Wistar-Kyoto (WKY) rats with a TRD phenotype and Wistar (WIS) rats as a normative comparison, we investigated behavioral and neuroplasticity-related responses to PSI, striving to shed light on the distinctive features of its antidepressant effects. OBJECTIVES: We set out to assess the behavioral impact of acute and prolonged PSI administration on WKY and WIS rats, employing Novel Object Recognition (NORT), Social Interaction (SI), and Forced Swimming Test (FST). Our secondary objectives involved exploring strain-specific alterations in neuroplasticity-related parameters, including brain-derived neurotrophic factor (BDNF) and activity-regulated cytoskeleton-associated protein (Arc). METHODS: Conducting post-acute and extended assessments after a single PSI administration, we applied behavioral tests and biochemical analyses to measure serum BDNF levels and neuroplasticity-related parameters in the prefrontal cortex. Statistical analyses were deployed to discern significant differences between the rat strains and assess the impact of PSI on behavioral and biochemical outcomes. RESULTS: Our findings uncovered significant behavioral disparities between WKY and WIS rats, indicating passive behavior and social withdrawal in the former. PSI demonstrated pronounced pro-social and antidepressant effects in both strains, each with its distinctive temporal trajectory. Notably, we identified strain-specific variations in BDNF-related signaling and observed the modulation of Arc expression in WKY rats. CONCLUSIONS: Our study delineated mood-related behavioral nuances between WKY and WIS rat strains, underscoring the antidepressant and pro-social properties of PSI in both groups. The distinct temporal patterns of observed changes and the identified strain-specific neuroplasticity alterations provide valuable insights into the TRD phenotype and the mechanisms underpinning the efficacy of PSI.

Longer-term Effect of Physical Activity Intervention on Sleep Quality: A Secondary Analysis of Cluster Randomized Controlled Trial.

STUDY OBJECTIVES: To examine the longer-term effect of physical activity (PA) intervention on sleep quality and whether the effect was heterogeneous between daytime nappers and non-nappers. METHODS: This study was a secondary analysis of a cluster randomized controlled trial in China. Eight villages were randomized 1:1 to intervention or control group. The intervention group received an 8-week PA intervention, while the control group did not. The primary outcome of this study was the change in the Pittsburgh Sleep Quality Index (PSQI) global score at 24 months. RESULTS: The 511 participants had a mean age of 70.94 years (SD 5.73) and 55.6% were female. The intervention showed improvements in the PSQI global score at 8 weeks (adjusted mean difference -1.05; P=0.002), and the effect diminished at 24 months (-0.64; P=0.06). There were statistically significant improvements in the PSQI global score for daytime nappers, but not for non-nappers at 8 weeks (adjusted mean difference -0.98; P=0.01 vs -1.27; P=0.05), 12 months (-0.86; P=0.03 vs -0.84; P=0.21), and 24 months (-0.80; P=0.04 vs -0.14; P=0.84), although these improvements were below the minimum detectible level of the PSQI which is 1 point. CONCLUSION: The 8-week PA intervention was effective in improving sleep quality, while the effect was diminished and below the minimum detectible level of the PSQI which is 1 point after 24 months. The effect of PA intervention on sleep quality was more pronounced in daytime nappers. Additional interventions (e.g., focusing on multiple behavioral interventions such as PA and healthy diet) are needed to maintain the beneficial effect of PA on sleep quality in the general older populations. Further research is required to confirm the mechanisms of the effect of napping and develop tailored interventions.

How long-term PM exposure may affect all-site cancer mortality: Evidence from a large cohort in southern China.

BACKGROUND: Evidence of a potential causal link between long-term exposure to particulate matter (PM) and all-site cancer mortality from large population cohorts remained limited and suffered from residual confounding issues with traditional statistical methods. AIMS: We aimed to examine the potential causal relationship between long-term PM exposure and all-site cancer mortality in South China using causal inference methods. METHODS: We used a cohort in southern China that recruited 580,757 participants from 2009 through 2015 and tracked until 2020. Annual averages of PM1, PM2.5, and PM10 concentrations were generated with validated spatiotemporal models. We employed a causal inference approach, the Marginal Structural Cox model, based on observational data to evaluate the association between long-term exposure to PM and all-site cancer mortality. RESULTS: With an increase of 1 µg/m³ in PM1, PM2.5, and PM10, the hazard ratios (HRs) and 95% confidence interval (CI) for all-site cancer were 1.033 (95% CI: 1.025-1.041), 1.032 (95% CI: 1.027-1.038), and 1.020 (95% CI: 1.016-1.025), respectively. The HRs (95% CI) for digestive system and respiratory system cancer mortality associated with each 1 µg/m³ increase in PM1 were 1.022 (1.009-1.035) and 1.053 (1.038-1.068), respectively. In addition, inactive participants, who never smoked, or who lived in areas of low surrounding greenness were more susceptible to the effects of PM exposure, the HRs (95% CI) for all-site cancer mortality were 1.042 (1.031-1.053), 1.041 (1.032-1.050), and 1.0473 (1.025-1.070) for every 1 µg/m³ increase in PM1, respectively. The effect of PM1 tended to be more pronounced in the low-exposure group than in the general population, and multiple sensitivity analyses confirmed the robustness of the results. CONCLUSION: This study provided evidence that long-term exposure to PM may elevate the risk of all-site cancer mortality, emphasizing the potential health benefits of improving air quality for cancer prevention.

Obesity as an independent risk factor for poor long-term outcome after mid-urethral sling surgery.

INTRODUCTION: High body mass index (BMI) is a risk-factor for stress urinary incontinence (SUI). Mid-urethral sling (MUS) surgery is an effective treatment of SUI. The aim of this study was to investigate if there is an association between BMI at time of MUS-surgery and the long-term outcome at 10 years. MATERIAL AND METHODS: Women who went through MUS surgery in Sweden between 2006 and 2010 and had been registered in the Swedish National Quality Register of Gynecological Surgery were invited to participate in the 10-year follow-up. A questionnaire was sent out asking if they were currently suffering from SUI or not and their rated satisfaction, as well as current BMI. SUI at 10 years was correlated to BMI at the time of surgery. SUI at 1 year was assessed by the postoperative questionnaire sent out by the registry. The primary aim of the study was to investigate if there is an association between BMI at surgery and the long-term outcome, subjective SUI at 10 years after MUS surgery. Our secondary aims were to assess whether BMI at surgery is associated with subjective SUI at 1-year follow-up and satisfaction at 10-year follow-up. RESULTS: The subjective cure rate after 10 years was reported by 2108 out of 2157 women. Higher BMI at the time of surgery turned out to be a risk factor for SUI at long-term follow-up. Women with BMI <25 reported subjective SUI in 30%, those with BMI 25-<30 in 40%, those with BMI 30-<35 in 47% and those with BMI ≥35 in 59% (p < 0.001). Furthermore, subjective SUI at 1 year was reported higher by women with BMI ≥30, than among women with BMI <30 (33% vs. 20%, p < 0.001). Satisfaction at 10-year follow-up was 82% among women with BMI <30 vs 63% if BMI ≥30 (p < 0.001). CONCLUSIONS: We found that higher BMI at the time of MUS surgery is a risk factor for short- and long-term failure compared to normal BMI.

Long-term effect of posterior nasal neurectomy for perennial allergic rhinitis.

BACKGROUND: Surgical treatment is recommended for patients with severe allergic rhinitis (AR) refractory to medical treatment. Endoscopic posterior nasal neurectomy (PNN) is primarily performed to improve rhinorrhea in severe perennial AR, however studies on its long-term prognosis are lacking. AIMS/OBJECTIVES: This study aimed to investigate the long-term prognosis of PNN. MATERIALS AND METHODS: A questionnaire survey was administered to 17 patients (12 men and 5 women) at least 1 year after PNN. Nasal symptoms and medications, as well as patient satisfaction with surgery at the time of survey, were scored. Furthermore, scores were compared between patients with postoperative periods of >5 years and <5 years. RESULTS: Nasal symptoms and medication scores significantly improved after surgery. There was no significant difference between patients with a postoperative period of >5 years and <5 years in both preoperative and postoperative nasal symptoms and medication scores. No correlation was found between patient satisfaction with surgery and postoperative period. CONCLUSIONS AND SIGNIFICANCE: PNN improved nasal symptoms and medication scores in patients with severe perennial AR. Furthermore, the study results suggest that the long-term effect of PNN for perennial AR lasts for >5 years. J. Med. Invest. 71 : 62-65, February, 2024.

Potential impact of blood cholesterol guidelines on statin treatment in the U.S. population using interrupted time series analysis.

BACKGROUND: The 2013 ACC/AHA Guideline was a paradigm shift in lipid management and identified the four statin-benefit groups. Many have studied the guideline's potential impact, but few have investigated its potential long-term impact on MACE. Furthermore, most studies also ignored the confounding effect from the earlier release of generic atorvastatin in Dec 2011. METHODS: To evaluate the potential (long-term) impact of the 2013 ACC/AHA Guideline release in Nov 2013 in the U.S., we investigated the association of the 2013 ACC/AHA Guideline with the trend changes in 5-Year MACE survival and three other statin-related outcomes (statin use, optimal statin use, and statin adherence) while controlling for generic atorvastatin availability using interrupted time series analysis, called the Chow's test. Specifically, we conducted a retrospective study using U.S. nationwide de-identified claims and electronic health records from Optum Labs Database Warehouse (OLDW) to follow the trends of 5-Year MACE survival and statin-related outcomes among four statin-benefit groups that were identified in the 2013 ACC/AHA Guideline. Then, Chow's test was used to discern trend changes between generic atorvastatin availability and guideline potential impact. RESULTS: 197,021 patients were included (ASCVD: 19,060; High-LDL: 33,907; Diabetes: 138,159; High-ASCVD-Risk: 5,895). After the guideline release, the long-term trend (slope) of 5-Year MACE Survival for the Diabetes group improved significantly (P = 0.002). Optimal statin use for the ASCVD group also showed immediate improvement (intercept) and long-term positive changes (slope) after the release (P < 0.001). Statin uses did not have significant trend changes and statin adherence remained unchanged in all statin-benefit groups. Although no other statistically significant trend changes were found, overall positive trend change or no changes were observed after the 2013 ACC/AHA Guideline release. CONCLUSIONS: The 2013 ACA/AHA Guideline release is associated with trend improvements in the long-term MACE Survival for Diabetes group and optimal statin use for ASCVD group. These significant associations might indicate a potential positive long-term impact of the 2013 ACA/AHA Guideline on better health outcomes for primary prevention groups and an immediate potential impact on statin prescribing behaviors in higher-at-risk groups. However, further investigation is required to confirm the causal effect of the 2013 ACA/AHA Guideline.

Effects of Four Weeks of In-Season Pre-Workout Supplementation on Performance, Body Composition, Muscle Damage, and Health-Related Markers in Basketball Players: A Randomized Controlled Study.

This randomized, double-blinded, experimental study investigated the effects of a four-week daily pre-workout supplementation (200 mg caffeine, 3.3 g creatine monohydrate, 3.2 g ß-alanine, 6 g citrulline malate, and 5 g BCAA) vs. placebo (isocaloric maltodextrin) on anaerobic (jumping, sprinting, agility, and the running-based anaerobic sprint test: RAST) and aerobic (Yo-Yo intermittent recovery test level 1) performance, as well as on body composition and selective muscle damage/health-related blood markers in well-trained basketball players during the in-season period. Eighteen basketball players (age: 24.4 ± 6.3 years, height: 185.7 ± 8.0 cm, weight: 85.7 ± 12.8 kg, body fat: 16.5 ± 4.2%) were randomly assigned into two groups: pre-workout supplement (PWS, n = 10) or placebo (PL, n = 8). PWS consumption increased aerobic performance (PWS: 8 ± 6%; PL: -2 ± 6%; p = 0.004) compared to PL. A significant decrease was observed in peak (F = 7.0; p = 0.017), average (F = 10.7; p = 0.005), and minimum power (F = 5.1; p = 0.039) following 4 weeks of supplementation in both groups. No other significant changes were observed between groups (p > 0.05). In conclusion, the consumption of the current PWS over a four-week period appears to positively influence the aerobic performance of well-trained basketball players during the in-season period. However, it does not appear to mitigate the observed decline in anaerobic power, nor does it affect performance in jumping, sprinting, and agility, or alter body composition or selective muscle damage/health-related blood markers.

Examining the long-term effects of COVID-19 in surgical nurses: Case of Aegean Region.

PURPOSE: To examine the long-term effects of COVID-19 on surgical nurses. BACKGROUND: Individuals contaminated with COVID-19 may face several metabolic or psychological issues, primarily in the respiratory, cardiovascular, nervous, musculoskeletal and renal systems during the late period. However, the long-term epidemiology is still not clear. DESIGN: Descriptive cross-sectional study. METHODS: The study included nurses (n = 509) who had been diagnosed with COVID-19 at least 12 weeks before and worked in surgical departments. We collected the study data via an online survey using the snowball sampling method between December 2021 and May 2022. This study followed the Reporting of Observational Studies in Epidemiology Guideline. RESULTS: The mean age of the nurses was 31.66 ± 8.74 years. Nurses stated that they were diagnosed with COVID-19 approximately 36 weeks before participating in this study. We found that the nurses mostly experienced palpitation (83.5%), headache (73.5%), dyspnea (64.1%), anosmia (57.6%), arthralgia (55.7%) and burnout (58.4%) during the late period after COVID-19. CONCLUSION: The long-term effects of COVID-19 were related to multiple organ dysfunctions. NO PATIENT OR PUBLIC CONTRIBUTION: Since the study was conducted with healthy individuals who had previously experienced COVID-19, there is no patient contribution. RELEVANCE TO CLINICAL PRACTICE: This study focuses on the long-term effects of COVID-19 on nurses. The results support the long-term effects of COVID-19 and are thought to contribute to the literature.

Post-traumatic growth in later-life cognitive function? Evidence from the 1976 Great Tangshan Earthquake.

OBJECTIVES: This study aimed to explore the long-term impacts of exposure to earthquake in adolescence on later-life cognitive function in China. METHODS: Data were from the 2015 China Health and Retirement Longitudinal Study (CHARLS). Our analytical sample comprised 4394 participants aged 49 to 78 from two birth cohorts born between 1937 and 1966: exposed cohort during adolescence (born between 1952 and 1966), and non-exposed cohort during adolescence (born between 1937 and 1951). We defined earthquake exposure as the exposure severity of the 1976 Great Tangshan Earthquake (GTE). We selected community environmental characteristics as our key moderators. A difference-in-differences (DID) method was employed to estimate the long-term impact of the GTE on later-life cognitive function. RESULTS: We found that exposure to the earthquake during adolescence resulted in higher scores of later-life cognitive function (for males: ß = 2.18; 95% CI: 0.70-3.66; for females: ß = 1.22; 95% CI: 0.11-2.33). For males, this impact was moderated by community environmental characteristics including the old-age allowance program (ß = 3.07; 95% CI: 1.94-4.19) and the condition of basic community infrastructures (ß = 1.52; 95% CI: 0.84-2.19). CONCLUSIONS: Our study supports the post-traumatic growth theory. This finding suggest that individuals with early-life traumatic exposure need to be focused on. Additionally, improving the conditions of community infrastructures and establishing a community environment with comfort and security may be pretty important for promoting cognitive function and post-traumatic growth.

Post-hypnotic suggestion improves confidence and speed of memory access with long-lasting effects.

In our study, we use the post-hypnotic suggestion of easy remembering to improve memory with long-lasting effects. We tested 24 highly suggestible participants in an online study. Participants learned word lists and recalled them later in a recognition memory task. At the beginning of the study, participants were hypnotized and the post-hypnotic suggestion to remember easily was associated with a cue that participants used during the recognition memory task. In a control condition, the same participants used a neutral cue. One week later, participants repeated both conditions with new word lists. Participants were significantly faster and more confident in their recognition ratings in the easy-remembering condition compared to the control condition, and this effect persisted over one week. Crucially, the increased speed and confidence in the easy-remembering condition did not affect memory accuracy. That makes our hypnosis intervention promising for patients experiencing subjective memory impairments.

Hidden danger: The long-term effect of ultrafine particles on mortality and its sociodemographic disparities in New York State.

Although previous studies have shown increased health risks of particulate matters, few have evaluated the long-term health impacts of ultrafine particles (UFPs or PM0.1, ≤ 0.1 µm in diameter). This study assessed the association between long-term exposure to UFPs and mortality in New York State (NYS), including total non-accidental and cause-specific mortalities, sociodemographic disparities and seasonal trends. Collecting data from a comprehensive chemical transport model and NYS Vital Records, we used the interquartile range (IQR) and high-level UFPs (≥75 % percentile) as indicators to link with mortalities. Our modified difference-in-difference model controlled for other pollutants, meteorological factors, spatial and temporal confounders. The findings indicate that long-term UFPs exposure significantly increases the risk of non-accidental mortality (RR=1.10, 95 % CI: 1.05, 1.17), cardiovascular mortality (RR=1.11, 95 % CI: 1.05, 1.18) particularly for cerebrovascular (RR=1.21, 95 % CI: 1.10, 1.35) and pulmonary heart diseases (RR=1.33, 95 % CI: 1.13, 1.57), and respiratory mortality (borderline significance, RR=1.09, 95 % CI: 1.00, 1.18). Hispanics (RR=1.13, 95 % CI: 1.00, 1.29) and non-Hispanic Blacks (RR=1.40, 95 % CI: 1.16, 1.68) experienced significantly higher mortality risk after exposure to UFPs, compared to non-Hispanic Whites. Children under five, older adults, non-NYC residents, and winter seasons are more susceptible to UFPs' effects.

House dust mite SCIT reduces asthma risk and significantly improves long-term rhinitis and asthma control-A RWE study.

BACKGROUND: The German Therapy Allergen Ordinance (TAO) triggered an ongoing upheaval in the market for house dust mite (HDM) allergen immunotherapy (AIT) products. Three HDM subcutaneous AIT (SCIT) products hold approval in Germany and therefore will be available after the scheduled completion of the TAO procedure in 2026. In general, data from clinical trials on the long-term effectiveness of HDM AIT are rare. We evaluated real-world data (RWD) in a retrospective, observational cohort study based on a longitudinal claims database including 60% of all German statutory healthcare prescriptions to show the long-term effectiveness of one of these products in daily life. Aim of this analysis was to provide a per product analysis on effectiveness of mite AIT as it is demanded by international guidelines on AIT. METHODS: Subjects between 5 and 70 years receiving their first (index) prescription of SCIT with a native HDM product (SCIT group) between 2009 and 2013 were included. The exactly 3:1 matched control group received prescriptions for only symptomatic AR medication (non-AIT group); the evaluation period for up to 6 years of follow-up ended in February 2017. Study endpoints were the progression of allergic rhinitis (AR) and asthma, asthma occurrence and time to the onset of asthma after at least 2 treatment years. RESULTS: In total, 892 subjects (608 adults and 284 children/adolescents) were included in the SCIT group and 2676 subjects (1824 adults and 852 children/adolescents) in the non-AIT group. During the follow-up period after at least 2 years of SCIT, the number of prescriptions in the SCIT group was reduced by 62.8% (p < .0001) for AR medication and by 42.4% for asthma medication (p = .0003). New-onset asthma risk was significantly reduced in the SCIT vs non-AIT group by 27.0% (p = .0212). The asthma-preventive effect of SCIT occurred 15 months after start of the treatment. In the SCIT group, the time to onset of asthma was prolonged compared to the non-AIT group (p = .0010). CONCLUSION: In this first product based RWD analysis on SCIT with a native HDM product, patients aged 5 to 70 years benefited from AIT in the long term in terms of reduced progression of AR and asthma after at least 2 years of treatment. The effects seemed to last for up to 6 years after treatment termination. A significantly reduced risk of asthma onset was observed, starting after 15 months of treatment.

Interprofessional collaboration skills and motivation one year after an interprofessional educational intervention for undergraduate medical and nursing students.

BACKGROUND: The increasingly complex patient care in the twenty-first century is delivered by interprofessional health care teams. Interprofessional collaboration can be taught during interprofessional education. However, whether a long-term change in collaborative competencies can be achieved by interprofessional education has not been studied sufficiently. Our research questions were: How does motivation for interprofessional collaboration and interprofessional collaborative skills change up to one year after an interprofessional educational intervention? How are they related to each other? METHODS: During a one-year period, undergraduate medical and nursing students attended four interprofessional (intervention) or uniprofessional (control group) education sessions. Self-determination Theory was used as the theoretical framework. Autonomous and controlled motivation scores for interprofessional collaboration were calculated using the Academic Self-Regulation Questionnaire, before (T1), directly after (T2) and one year post-intervention (T3). At T3, the students also filled out the Interprofessional Collaborative Competencies Attainment Survey (ICCAS), which measured the perceived attainment of collaborative competencies by a retrospective pre-test/post-test design. We used linear mixed effects models to analyse the motivation scores and linear regression for the relation between motivation and competence. RESULTS: In the interprofessional group, autonomous motivation scores of the participants were significantly lower at T2 vs. T1. Controlled motivation scores were significantly higher at T3 vs. T1. Controlled motivation scores for T2 were significantly higher in the uniprofessional group than in the interprofessional group. Perceived competence was related to higher autonomous motivation scores. At T3 the interprofessional collaborative competencies seemed to have grown more among students in the interprofessional group. CONCLUSIONS: The perceived growth in interprofessional collaboration competence lasted at least up to one year after the intervention, and was measurable with the ICCAS. The growth was significantly more in the IPE students than in the UPE students. The few differences found in motivation scores for interprofessional collaboration were probably caused by an imbalance of nursing versus medical students over the different time points. This finding indicates that classroom based IPE can contribute to interprofessional collaboration skills of nursing and medical students at least up to one year after an intervention.

Effectiveness of financial incentives on influenza vaccination among older adults in China: a randomized clinical trial.

OBJECTIVES: To investigate the short-term and long-term effectiveness of different levels of financial incentives on increasing the willingness to vaccinate and vaccine uptake. METHODS: A randomized controlled trial was conducted to investigate the effectiveness of financial incentives of three groups with monetary incentives (CNY 20, CNY 40, and CNY 60; 1 CNY = 0.13 EUR) vs. a control group-CNY 0-on influenza vaccine uptake among 720 older adults (≥60 years) in Beijing, China. The primary outcome was vaccine uptake, and the secondary outcomes were intention to vaccinate and length of time to immunization. RESULTS: Financial incentive significantly promoted higher intention to influenza vaccination (120/178 [67.42%] vs. 442/542 [81.55%]; Relative Risk [RR], 1.21; 95% CI, 1.02-1.42) and higher vaccination participation (74/178 [41.57%] vs. 316/542 [58.30%]; RR, 1.39; 95% CI, 1.10-1.75). CNY 60 had the largest impact on the intention to vaccinate (15.00% vs. 13.48% and 13.90%) and vaccination uptake (19.42% vs. 14.05% and 16.67%) compared with CNY 20 and CNY 40. Time to vaccination was significantly lower among participants receiving incentives than those without ([37.21 days; 95% CI, 34.33-39.99] vs. [48.27 days; 95% CI, 43.47-53.07]; Hazard Ratio [HR] 1.57, 95% CI 1.22-2.03). We found no long-term influence of financial incentives on vaccination decisions in the following year (217/542, 40.04% vs. 65/178, 36.52%; RR 1.08, 95% CI 0.82-1.42). DISCUSSION: Our study suggests that modest financial incentives will boost short-term influenza vaccination rates and shorten the length of time to immunization in China. No one single-time financial incentive had a long-term effect on future vaccination behaviours or helped establish regular vaccination behaviours.

Effectiveness and safety of intraoperative intraperitoneal 5-Fu drug implantation in patients with colorectal cancer: a retrospective cohort study.

PURPOSE: The purpose of this clinical study was to evaluate the efficacy and safety of intraoperative chemotherapy (IOC) with intraoperative intraperitoneal implantation of 5-fluorouracil (5-FU) in colorectal cancer (CRC) patients. METHODS: In this study, 165 patients who underwent colorectal radical surgery were selected, of whom 111 in the experimental group received surgical treatment with an intraperitoneal 5-fluorouracil (5-FU) implantation. Fifty-four patients who did not undergo intraperitoneal implantation of 5-FU were matched to compare the progression-free survival (PFS) and overall survival (OS) with the former. RESULTS: We also studied the differences in the changes of different biochemical indicators between the two groups before and after surgery, and there were significant differences in leukocytes, neutrophils, and lymphocytes before and after (P < 0.05), while for sodium ions, potassium ions, platelets, alanine transaminase, aspartate transaminase, creatinine, urea, and albumin, there were no significant differences. This may be related to the intraperitoneal chemotherapy implant entering the blood circulation. For 5-year OS, there were 85/111 (76.58%) in the 5-FU group (P = 0.013) and 35/54 (64.81%) in the control group; for 5-year PFS, there were 84/111 (75.68%) in the 5-FU group and 29/54 (53.70%) in the control group (P = 0.02). All the experimental groups were better than the control group with a significant difference in the experimental results. CONCLUSION: For CRC surgery patients, intraperitoneal implantation of slow-release 5-FU drugs, which is a safe and simple procedure, can improve the prognosis of the patients. CLINICAL TRIAL REGISTRATION: No clinical trials were performed in the study.

Challenges of Air Pollution and Health in East Asia.

PURPOSE OF REVIEW: Air pollution has been a serious environmental and public health issue worldwide, particularly in Asian countries. There have been significant increases in epidemiological studies on fine particulate matter (PM2.5) and ozone pollution in East Asia, and an in-depth review of epidemiological evidence is urgent. Thus, we carried out a systematic review of the epidemiological research on PM2.5 and ozone pollution in East Asia released in recent years. RECENT FINDINGS: Recent studies have indicated that PM2.5 and ozone are the most detrimental air pollutants to human health, resulting in substantial disease burdens for Asian populations. Many epidemiological studies of PM2.5 and ozone have been mainly performed in three East Asian countries (China, Japan, and South Korea). We derived the following summary findings: (1) both short-term and long-term exposure to PM2.5 and ozone could raise the risks of mortality and morbidity, emphasizing the need for continuing improvements in air quality in East Asia; (2) the long-term associations between PM2.5 and mortality in East Asia are comparable to those observed in Europe and North America, whereas the short-term associations are relatively smaller in magnitude; and (3) further cohort and intervention studies are required to yield robust and precise evidence that can promote evidence-based policymaking in East Asia. This updated review presented an outline of the health impacts of PM2.5 and ozone in East Asia, which may be beneficial for the development of future regulatory policies and standards, as well as for designing subsequent investigations.

National Smoking Cessation Services (NSCS) enrollment and their effect on long-term tobacco cessation in Korea: Results from a 1-year prospective follow-up of NSCS participants.

INTRODUCTION: The study aimed to identify predictors associated with long-term tobacco cessation at 12-month follow-up among users of the National Smoking Cessation Services (NSCS) in Korea. METHODS: To measure the long-term effect of NSCS delivery, the target sample size of 5167 adult smokers registered in the NSCS in 2018 was enrolled with proportional random sampling. A multiple logistic regression analysis (crude, adjusted) was performed to identify the changes in smoking status at the 12-month follow-up after the last NSCS enrollment and the potential factors associated with changes in smoking status. RESULTS: The response rate to reach the number of subjects targeted was 22.4%. A total of 41.2% of the tobacco users enrolled had successfully quit at baseline, and the 7-day point prevalence of tobacco cessation at the follow-up at 12 months, via a telephone survey, was 34.4%. Factors positively associated with cessation at the 12-month follow-up were longer experience with tobacco abstinence and additional quitting attempts with or without NSCS enrollment, although every additional quit attempt with NSCS use had a better outcome. In addition, having a successful quit outcome with NSCS use at the baseline and having more satisfaction with the service of professional counseling or incentives than others provided by NSCS, increased cessation at follow-up after adjustment of other factors considered. CONCLUSIONS: In addition to multiple quitting attempts, longer experience with tobacco abstinence, and additional enrollment in NSCS, the service experience, and satisfaction with the content that NSCS offered, might improve the lasting success of abstinence. These results might be considered to improve the contents and protocols of the NSCS for better outcomes.
