Periodontal therapy for hopeless mandibular anterior teeth: a retrospective case report with a multidisciplinary approach and a 20-year follow-up

Introduction: This case report presents the intentional periodontal maintenance of two periodontal hopeless lower central incisors with a multidisciplinary approach and 20-year follow-up. Case presentation: A 36-year-old male, in 2001, was diagnosed with aggressive periodontitis, gingival swelling, bleeding, and mandibular central incisors with mobility and poor prognosis. Following periodontal therapy (phase I), root canal treatment, and occlusal adjustment, #31 and #41 were gently extracted to remove the granulation tissues, calculus, and infected cementum from the root surface. Then, tetracycline-HCl was applied for 5 minutes on the root surfaces. The teeth were repositioned into the sockets and splinted with a lingual bar. At 3 months, the bar was removed, and a free gingival autogenous graft was done to improve the local keratinized tissue width. Mobility scores, pocket depths, and clinical attachment levels were recorded, and radiographs were taken at 1, 5, and 20 years. The 5-year follow-up showed that the teeth were clinically and radiographically in function. There was a reduction in probing depth and a gain in clinical attachment and radiographic alveolar bone levels. After 20 years, #41 was stable, but #31 had external root resorption, leading to a new treatment plan (dental implants) and extraction. Conclusion: The clinical result of this case was satisfactory for 20 years. Intentional periodontal maintenance of the teeth may be an alternative treatment, even considering the high level of complexity.

Quantitative impacts of meteorology and emissions on the long-term trend of O3 in the Yangtze River Delta (YRD), China from 2015 to 2022.

Extensive spatiotemporal analyses of long-trend surface ozone in the Yangtze River Delta (YRD) region and its meteorology-related and emission-related have not been systematically analyzed. In this study, by using 8-year-long (2015-2022) surface ozone observation data, we attempted to reveal the variation of multiple timescale components using the Kolmogorov-Zurbenko filter, and the effects of meteorology and emissions were quantitatively isolated using multiple linear regression with meteorological variables. The results showed that the short-term, seasonal, and long-term components accounted for daily maximum 8-hr average O3 (O3-8 hr) concentration, 46.4%, 45.9%, and 1.0%, respectively. The meteorological impacts account for an average of 71.8% of O3-8 hr, and the YRD's eastern and northern sections are meteorology-sensitive areas. Based on statistical analysis technology with empirical orthogonal function, the contribution of meteorology, local emission, and transport in the long-term component of O3-8 hr were 0.21%, 0.12%, and 0.6%, respectively. The spatiotemporal analysis indicated that a distinct decreasing spatial pattern could be observed from coastal cities towards the northwest, influenced by the monsoon and synoptic conditions. The central urban agglomeration north and south of the YRD was particularly susceptible to local pollution. Among the cities studied, Shanghai, Anqing, and Xuancheng, located at similar latitudes, were significantly impacted by atmospheric transmission-the contribution of Shanghai, the maximum accounting for 3.6%.

A methodological framework for estimating ambient PM2.5 particulate matter concentrations in the UK.

Scientific evidence sustains PM2.5 particles' inhalation may generate harmful impacts on human beings' health; therefore, their monitoring in ambient air is of paramount relevance in terms of public health. Due to the limited number of fixed stations within the air quality monitoring networks, development of methodological frameworks to model ambient air PM2.5 particles is primordial to providing additional information on PM2.5 exposure and its trends. In this sense, this work aims to offer a global easily-applicable tool to estimate ambient air PM2.5 as a function of meteorological conditions using a multivariate analysis. Daily PM2.5 data measured by 84 fixed monitoring stations and meteorological data from ERA5 (ECMWF Reanalysis v5) reanalysis daily based data between 2000 and 2021 across the United Kingdom were attended to develop the suggested approach. Data from January 2017 to December 2020 were employed to build a mathematical expression that related the dependent variable (PM2.5) to predictor ones (sea-level pressure, planetary boundary layer height, temperature, precipitation, wind direction and speed), while 2021 data tested the model. Evaluation indicators evidenced a good performance of model (maximum values of RMSE, MAE and MAPE: 1.80 µg/m3, 3.24 µg/m3, and 20.63%, respectively), compiling the current legislation's requirements for modelling ambient air PM2.5 concentrations. A retrospective analysis of meteorological features allowed estimating ambient air PM2.5 concentrations from 2000 to 2021. The highest PM2.5 concentrations relapsed in the Mid- and Southlands, while Northlands sustained the lowest concentrations.

Comparison of long-term quality of life and their predictors in survivors between paediatric and adult nasopharyngeal carcinoma in the intensity-modulated radiotherapy era.

BACKGROUND: To compare the differences in long-term quality of life (QoL) between survivors of paediatric and adult patients with nasopharyngeal carcinoma (NPC) and assess the clinical factors that predict long-term QoL. METHODS: We enrolled 420 long-term NPC survivors who were alive for at least 8 years after treatment, including 195 paediatric and 225 adult patients diagnosed and treated with intensity-modulated radiotherapy (IMRT) at Sun Yat-sen University Cancer Centre (SYSUCC) between 2011 and 2015. Data on clinical factors and EORTC QLQ-C30 were collected from all participants. The QoL of paediatric and adult NPC survivors was compared. RESULTS: The paediatric group had significantly better outcomes in global health status (paediatric: 80.2 ± 12.7; adult: 77.2 ± 11.5; P = 0.027), physical function (paediatric: 98.5 ± 4.6; adult: 95.1 ± 7.0; P < 0.001), role function (paediatric: 97.0 ± 9.2; adult: 90.5 ± 15.2; P < 0.001), social function (paediatric: 96.0 ± 8.9; adult: 93.5 ± 11.8; P = 0.038), insomnia (paediatric: 1.9 ± 7.8; adult: 13.1 ± 22.3; P < 0.001), constipation (paediatric: 1.3 ± 7.5; adult: 8.0 ± 17.4; P < 0.001), diarrhea (paediatric: 0.7 ± 4.6; adult: 2.8 ± 9.3; P = 0.010), and financial difficulties (paediatric: 1.9 ± 7.8; adult: 11.0 ± 19.8; P < 0.001), but poorer cognitive function (paediatric: 88.3 ± 9.9; adult: 93.8 ± 12.6; P < 0.001) than the adult group. Pretreatment clinical factors, including T stage, N stage, and pre-treatment EBV (Epstein-Barr Virus) DNA, showed a strong association with QoL. However, the factors that affected the QoL outcomes differed between the two groups. In survivors of paediatric cancer, global health status/QoL was strongly correlated with T stage (P < 0.001) and clinical stage (P = 0.018), whereas it was strongly correlated with pre-treatment EBV DNA (P = 0.008) in adults. CONCLUSION: Paediatric survivors of NPC have a significantly better QoL than adult NPC survivors. Moreover, pre-treatment T stage, N stage, and EBV DNA significantly influenced the overall health status of the survivors. These results highlight the need to tailor care to both age groups to promote better long-term health outcomes.

Long-Term Exposure of Fresh and Aged Nano Zinc Oxide Promotes Hepatocellular Carcinoma Malignancy by Up-Regulating Claudin-2.

Background: Tumor development and progression is a long and complex process influenced by a combination of intrinsic (eg, gene mutation) and extrinsic (eg, environmental pollution) factors. As a detoxification organ, the liver plays an important role in human exposure and response to various environmental pollutants including nanomaterials (NMs). Hepatocellular carcinoma (HCC) is one of the most common malignant tumors and remains a serious threat to human health. Whether NMs promote liver cancer progression remains elusive and assessing long-term exposure to subtoxic doses of nanoparticles (NPs) remains a challenge. In this study, we focused on the promotional effects of nano zinc oxide (nZnO) on the malignant progression of human HCC cells HepG2, especially aged nZnO that has undergone physicochemical transformation. Methods: In in vitro experiments, we performed colony forming efficiency, soft agar colony formation, and cell migration/invasion assays on HepG2 cells that had been exposed to a low dose of nZnO (1.5 µg/mL) for 3 or 4 months. In in vivo experiments, we subcutaneously inoculated HepG2 cells that had undergone long-term exposure to nZnO for 4 months into BALB/c athymic nude mice and observed tumor formation. ZnCl2 was administered to determine the role of zinc ions. Results: Chronic low-dose exposure to nZnO significantly intensified the malignant progression of HCC cells, whereas aged nZnO may exacerbate the severity of malignant progression. Furthermore, through transcriptome sequencing analysis and in vitro cellular rescue experiments, we demonstrated that the mechanism of nZnO-induced malignant progression of HCC could be linked to the activation of Claudin-2 (CLDN2), one of the components of cellular tight junctions, and the dysregulation of its downstream signaling pathways. Conclusion: Long-term exposure of fresh and aged nZnO promotes hepatocellular carcinoma malignancy by up-regulating CLDN2. The implications of this work can be profound for cancer patients, as the use of various nanoproducts and unintentional exposure to environmentally transformed NMs may unknowingly hasten the progression of their cancers.

Heart Transplantation and Left Ventricular Assist Devices: Long-Term Prognosis and Effects on Mental Health.

Heart transplantation and left ventricular assist devices (LVADs) have emerged as crucial interventions for end-stage heart failure, dramatically improving patient outcomes. This narrative review examines their historical context, indications, procedures, and outcomes, as well as their impact on long-term survival, quality of life, functional status, and mental health. While heart transplantation remains the optimal treatment, donor scarcity limits its application. LVADs have become a viable alternative, either as a bridge to transplantation or as destination therapy. Both interventions demonstrate similar long-term survival rates and significant improvements in health-related quality of life and functional status. However, they present distinct long-term management challenges, including immunosuppression needs for transplant recipients and device-related issues for LVAD patients. Mental health effects are considerable, necessitating psychological support and adaptive coping strategies. Complications such as infection, bleeding, and thrombosis remain concerns for both interventions. Patient selection criteria, technological advancements, and long-term management strategies are critical factors in optimizing outcomes. Future research should focus on device miniaturization, enhanced biocompatibility, and less invasive insertion techniques to further advance these therapies and improve patient care in end-stage heart failure.

Long-term effectiveness of the nine-valent human papillomavirus vaccine: Interim results after 12 years of follow-up in Scandinavian women.

A pivotal study in women aged 16-26 years demonstrated that the nine-valent human papillomavirus (9vHPV) vaccine was efficacious against high-grade cervical dysplasia related to the HPV types covered by the vaccine. To evaluate whether effectiveness remains above 90% for up to 14 years post-vaccination, a long-term follow-up (LTFU) extension of the study was conducted in Denmark, Norway, and Sweden (N = 2,029). Interim findings at 12 years post-vaccination are reported. Effectiveness of the vaccine was measured by comparing the percentage reduction in incidence of HPV16/18/31/33/45/52/58-related high-grade cervical dysplasia in the LTFU cohort with the expected incidence in an unvaccinated cohort. Cervical pre-cancer/cancer diagnoses were identified using national health registries. Tissue samples were obtained from national and regional biobanks for polymerase chain reaction HPV testing, and pathology diagnosis adjudication. Potential waning of vaccine effectiveness and statistical significance were assessed using a control chart method. During LTFU, there were no cases of HPV16/18/31/33/45/52/58-related high-grade cervical dysplasia over 10,396.2 person-years' follow-up in the per-protocol effectiveness population (n = 1,628). No signals indicated vaccine effectiveness decreasing below 90%. Statistically significant protection was provided by the 9vHPV vaccine through at least 10 years, with complete, although not statistically significant, effectiveness through 12 years.

DiDBiT-TMT: A Novel Method to Quantify Changes in the Proteomic Landscape Induced by Neural Plasticity.

Direct detection of biotinylated proteins (DiDBiT) is a proteomic method that can enrich and detect newly synthesized proteins (NSPs) labeled with bio-orthogonal amino acids with 20-fold improved detectability compared to conventional methods. However, DiDBiT has currently been used to compare only two conditions per experiment. Here, we present DiDBiT-TMT, a method that can be used to quantify NSPs across many conditions and replicates in the same experiment by combining isobaric tandem mass tagging (TMT) with DiDBiT. We applied DiDBiT-TMT to brain slices to determine changes in the de novo proteome that occur after inducing chemical long-term potentiation (cLTP) or treatment with the neuromodulator norepinephrine. We successfully demonstrated DiDBiT-TMT's capacity to quantitatively compare up to 9 samples in parallel. We showed that there is a minimal overlap among NSPs that are differentially expressed in cLTP-treated organotypic brain slices, norepinephrine-treated organotypic brain slices, and organotypic slices undergoing combinatorial treatment with norepinephrine and cLTP. Our results point to the possible divergence of the molecular mechanisms underlying these treatments and showcase the applicability of DiDBiT-TMT for studying neurobiology.

How a constructed wetland within a natural park enhances plankton communities after more than 10 years of operation: changes over space and time.

Constructed wetlands are increasingly used as a solution to treat polluted water in natural environments. Located in the Albufera de València Natural Park, a constructed wetland was built in 2009 as a pilot project to act as an intermediary between low-quality waters and the largest protected coastal lagoon in the Iberian Peninsula. With a unique dataset spanning more than a decade (2009-2023), this study assessed changes in plankton communities both spatially (comparing six sampling sites) and temporally (comparing four periods of years). The results show how the constructed wetland, after nearly 15 years of operation, has not only maintained but also improved its capacity to enhance the biological quality of the water which is released into the protected lagoon, thus fulfilling one of the main aims of its construction. During the last period (2020-2023) of the time series, the constructed wetland outlets had significantly higher zooplankton biomass, particularly filter-feeding cladocerans, compared to the inlets. This clear improvement in the plankton community was due to management interventions (e.g., drying sectors of the constructed wetland during the summers since 2019) and the rise in temperature. These circumstances promoted earlier hatching of cladoceran diapause eggs from the sediments compared to previous years, maintaining their presence throughout all seasons. Consequently, the outlets of the constructed wetland had significantly lower phytoplankton abundance and sestonic chlorophyll-a concentrations than in the past, nearly oligotrophic states, and a reduced biovolume of potentially toxic cyanobacteria in the released waters.

Decoding Paradoxical Links of Cytokine Markers in Cognition: Cross talk between Physiology, Inflammaging, and Alzheimer's Disease- Related Cognitive Decline.

Recent research has revolutionized our understanding of memory consolidation by emphasizing the critical role of astrocytes, microglia, and immune cells in through cytokine signaling. Cytokines, compact proteins, play pivotal roles in neuronal development, synaptic transmission, and normal aging. This review explores the cellular mechanisms contributing to cognitive decline in inflammaging and Alzheimer's disease, highlighting the paradoxical effects of most studied cytokines (IL-1, IL-6, TNF-α) in brain function, which act as a double-edged sword in brain physiology, acting both as facilitators of healthy cognitive function and as a potential contributor to cognitive decline.

Inclusion of people with multiple long-term conditions in pregnancy research: patient, public and stakeholder involvement and engagement in a randomised controlled trial.

BACKGROUND: Both pregnant women and those with multiple long-term conditions are under-served groups in clinical research. Informing and improving research through patient and public involvement, including pregnant women with two or more long-term health conditions, is critical to increasing their inclusion in maternity research. Giant PANDA is a randomised controlled trial, evaluating the effect of a treatment initiation strategy with nifedipine versus labetalol on severe maternal hypertension and a composite outcome of fetal/neonatal death, or neonatal unit admission. We aimed to undertake a mixed methods study-within-a-project within the Giant PANDA trial to understand barriers and facilitators to participation, understand and optimise current representativeness of clinical trial delivery of those with multiple long-term conditions and co-create a checklist to support their inclusion in pregnancy research. METHODS: We undertook online workshops with women with lived experience and hybrid workshops with healthcare professionals who look after women with multiple long-term conditions. A site audit of Giant PANDA sites provided insights into research delivery capacity and health system set-up, and how this influences inclusion. An extension to the Giant PANDA screening log captured data on multiple long-term conditions enabling analysis of the impact of these health conditions on women's inclusion in the trial. We co-created a checklist of recommendations for those designing and recruiting to similar clinical trials. RESULTS: Five key recommendations were identified including a need to (1) involve women with multiple long-term conditions as partners in maternity research and (2) minimise barriers that stop them from taking part through (3) designing and delivering research that is flexible in time and place (4) consider research as part of care for everyone, including those with multiple long-term conditions and (5) measure and report inclusion of those with two or more health conditions in maternity research. Multiple long-term conditions were not a barrier to recruitment or randomisation in the Giant PANDA trial. CONCLUSION: Women with multiple long-term conditions would like opportunities to find out about and participate in research which accounts for their needs. Our checklist aims to support those designing and delivering maternity research to optimise inclusion of individuals with multiple-long term conditions. TRIAL REGISTRATION: Giant PANDA: EudraCT number: 2020-003410-12, ISRCTN: 12,792,616.

Pregnant women with two or more long-term health problems may be less likely to be included in research. Including them in research is important to ensure we give the best care. Giant PANDA is a study comparing two medicines (nifedipine or labetalol) to manage high blood pressure in pregnancy. As part of the study, we looked at the number of women with two or more long-term health conditions included. We talked to women with experience of two or more long-term health conditions in pregnancy, and healthcare staff who look after these women. Finally, we looked at how maternity research is set up in Giant PANDA study sites. We found that women with two or more health conditions were taking part in the Giant PANDA study. Women with two or more long-term conditions would like the choice to be included in research which considers their needs. This includes being involved in the planning and ongoing support for studies. Research needs to be part of routine care, flexible, and not time consuming to help those with two or more health conditions take part. Our findings have been used to make a checklist to help plan and support studies for women and birthing people with two or more long-term health conditions.

Dependability and Prognostic Value of Biomarkers in COVID-19 Associated Rhino-Orbito- Cerebral Mucormycosis- A Long Term Ambispective Study.

COVID-19 pandemic, which has exhibited a wide clinical spectrum and an unexpected surge in mucormycosis cases, understanding various biomarkers' roles becomes pivotal. As mucormycosis leads to clinical morbidity and mortality through angioinvasion and thromboembolism, unveiling the correlation between these markers and disease progression can shed light on the reasons behind mucormycosis's emergence as an epidemic, especially following the second wave of COVID-19. This long term ambispective observational study, conducted from May 2020 to July 2023, aimed to assess specific biomarkers as predictors of severity in COVID-19-associated mucormycosis (CAM). Biomarkers measured included ESR, CRP, D-dimer, IL-8, PCT, serum ferritin, and neutrophil-lymphocyte ratio (NLR) at different time points. Data analysis employed descriptive statistics, repeated measure ANOVA, Spearman correlations, ROC curve analysis, and logistic regression. Of 290 patients, 198 completed the 2-year follow-up. Elevated baseline biomarker levels significantly decreased with treatment initiation. CRP and NLR emerged as significant predictors of severe CAM, with odds ratio 2.926 (95% CI 1.466-4.360) and 2.203 (95% CI 0.863-1.040) respectively. Factors influencing CAM progression included age, CRP, and NLR, while all biomarkers independently predicted mortality. A death prediction model using CRP, PCT, D-dimer, NLR, and IL-8 demonstrated exceptional performance, with a sensitivity of 83.1% and specificity of 100%. Elevated inflammatory markers in CAM patients showed a decline with treatment, with NLR and CRP proving crucial for predicting severity. Serial monitoring of IL-8, CRP, PCT, NLR, D-dimer, and ferritin provides insights into disease progression and prognosis. The study underscores the importance of biomarker assessment in managing CAM, especially in the context of the unpredictable clinical spectrum of COVID-19 and the subsequent mucormycosis surge.

Sperm quality and in vitro fertilizing ability of boar spermatozoa stored at 4 °C versus conventional storage for 1 week.

Introduction: Since boar spermatozoa show a marked deterioration in sperm quality when cooled, insemination doses are usually stored at 16-18 °C. However, maintaining this temperature during transport of semen doses is challenging, particularly during the summer months. An alternative could be to store the doses at 4 °C if cold-shock to the sperm could be prevented. The objective of this study was to evaluate boar sperm quality and fertility in in vitro fertilization after storage in AndroStar Premium at 4 °C for 1 week. Methods: Insemination doses (n = 9) in AndroStar Premium from a commercial boar semen collection station were transported to the laboratory at approximately 20 °C. At the laboratory, sperm quality evaluation and was preformed and each dose was split; half of each ejaculate was stored in a climate-controlled box at 16-18 °C, the other was slowly cooled to 4 °C. Both samples were stored for 1 week before further sperm quality evaluation and in vitro fertilization (IVF) were performed. Mean values were tested using generalized linear regression, with treatment and boar as fixed factors; p ≤ 0.05 was considered significant. Results: Sperm membrane integrity (mean ± sem: 91 ± 0.05 and 83 ± 0.09% for 16 and 4 °C, respectively) and superoxide production (6.79 ± 2.37 and 13.54 ± 6.23% for 16 and 4 °C, respectively), were different between treatments. The DNA fragmentation index was lower in cold-stored samples than in conventionally stored samples (3.74 ± 2.25 and 7.40 ± 3.36% for 4 and 16 °C, respectively). The numbers of oocytes developing to blastocyst on Day 6 (mean ± sd: 9.0 ± 8.0 and 6.0 ± 5.0%, for storage at 16 and 4 °C, respectively) were not different between treatments. Discussion: Therefore, storage of boar semen doses in AndroStar Premium at 4 °C for up to 7 days would be a viable alternative to current praxis.

Incidence of Pediatric to Adult Transition Among Tracheotomy Patients.

OBJECTIVE: To estimate the incidence and identify predictors of pediatric tracheostomy patients who transition into adulthood with a tracheostomy. METHODS: We conducted a retrospective analysis of pediatric tracheostomy patients treated at a single tertiary care pediatric hospital between 2009 and 2022. Patient demographics, comorbidities, tracheostomy outcomes, including decannulation and mortality rates, and the status of those alive with a tracheostomy at adulthood were compared. RESULTS: Of the 663 children who underwent a tracheostomy, 103 (15.5%) would have surpassed 18 years by September 1, 2023. Detailed breakdown: 26 (25%) were alive with a tracheostomy, 35 (34%) had been decannulated, 25 (24%) had passed away, and 17 (16.5%) were lost to follow-up. Patients who retained their tracheostomies into adulthood were more likely to be older at tracheostomy placement (mean age 14.3 vs. 1.7 years, p < 0.001), Hispanic (43.7% vs. 30.5%, p = 0.003), not ventilated at initial discharge (41% vs. 24%, p < 0.001), and have severe neurocognitive disabilities (72% vs. 53%, p < 0.001). Logistic regression identified older age at tracheostomy placement (OR = 1.35, 95% CI [1.24-1.48]) and severe neurocognitive disability (OR = 6.20, 95% CI [2.13-18.09]) as significant predictors of maintaining a tracheostomy into adulthood. CONCLUSIONS: Older age at tracheostomy placement and severe neurocognitive disabilities significantly predict the transition of pediatric tracheostomy patients to adult care with their tracheostomies. These findings highlight the need for specialized transition programs tailored to the needs of this unique population. LEVEL OF EVIDENCE: IV Laryngoscope, 2024.

Association between willingness to exercise and incident disability in older adults: a prospective longitudinal cohort study.

PURPOSE: To investigate whether the willingness to exercise (WTE) and exercise habits affect the incidence of disability among older adults. METHODS: This study included 8,354 individuals (72.5 ± 6.2 years, 55.9% female). The participants were divided into three categories based on their WTE: unwillingness to exercise, willingness to exercise (but without exercise habits), and exercise habits. The incidence of disability was prospectively determined within 24 months of the follow-up. Cox regression analysis was used to examine the relationship between WTE and the incidence of disability. RESULTS: Overall, 600 (7.2%), 4,703 (56.3%), and 3,051 (36.5%) participants were classified as unwillingness to exercise, willingness to exercise, and exercise habits, respectively. Compared with the unwillingness to exercise group, the willingness to exercise group (hazard ratio [HR] 0.71, 95%Confidence Interval [CI] 0.52-0.96) and the exercise habits group (HR 0.65, 95%CI 0.46-0.92) had a lower risk of disability incidence. CONCLUSIONS: These results suggest that WTE reduces the risk of disability in older adults. Therefore, the importance of increasing WTE to prevent the occurrence of disabilities is clear. Our results suggest that even though physical activity declines with age, it is important to have the desire to exercise and develop exercise habits.

Posttreatment health interventions for adult cancer survivors and their families: an integrated review.

PURPOSE: This review aimed to synthesize the literature regarding health interventions delivered to adult cancer survivors and their families during posttreatment phase. METHODS: An integrative literature review was conducted that included quantitative and qualitative studies. The search was carried out in four databases using the same terms or MeSH terms and included data from January 2012 to February 2024. After quality assessment, data were extracted and synthesized. The protocol was registered in PROSPERO. RESULTS: Among the seven studies included, two studies were randomized controlled trials, three were observational, and two utilized a qualitative approach. The studies originated from France, Australia, Canada, the UK, and the USA. In total, 704 participants were included, 294 were cancer survivors, 40 were non-cancer patients, 271 were family and caregivers, and 99 were healthcare professionals. The studies assessed survival durations after cancer treatment, ranging from 18 months to 6 years. The sparse interventions found across the studies used a multifaceted approach tailored to address various aspects of cancer survivorship and caregiver support. CONCLUSION: This review provides insights into the complex landscape of posttreatment support requirements for cancer survivors and their family caregivers. This finding underscores the critical necessity for additional intervention research involving comprehensive, accessible, and supportive services that address the multifaceted dimensions of survivorship for the patient and family as a unit.

Long-Run Impacts of an Early-life Nutrition Program: Evidence from the Introduction of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).

OBJECTIVES: To study how access to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) during the prenatal and early childhood periods affects long-term health outcomes of the affected cohorts. METHODS: In order to identify the effects of the WIC program, we exploit variations in the timing of its introduction in different counties and analyze future health indicators of affected cohorts. We use the restricted version of the Panel Study of Income Dynamics, which includes county-level identifiers through the interview year 2019. RESULTS: Our findings suggest that extending WIC access by one month correlates with a 0.2-0.3% point decrease in asthma incidence (p < 0.1 to p < 0.01) of affected cohorts. Although the connection between WIC and asthma is not fully understood, existing studies suggest potential pathways. Micronutrient deficiencies during early life can impact immune function and inflammation, both relevant to asthma. Moreover, adopting healthier dietary habits may improve microbiome composition, lowering asthma risk. Other indirect benefits of WIC, such as increased use of preventive healthcare services, may also contribute to the prevention of asthma. Despite uncertainties, these estimates remain robust across various model specifications. CONCLUSIONS FOR PRACTICE: Our study implies that early-life nutritional support programs such as WIC may alleviate the burden of asthma, although the specific mechanisms and effect sizes remain unclear. Given the substantial impact of asthma in the U.S., our findings underscore the potential long-term benefits of early-life nutritional support programs for lifelong health.

Recurrence rates with long-term follow-up after hallux valgus surgical treatment using shaft metatarsal osteotomies: a systematic review and meta-analysis.

Purpose: Recurrence of hallux valgus (HV) following corrective surgery is a frequent concern. A recent systematic review estimated recurrence of HV in only 4.9%, which may be an underestimation, as most included studies had short- to mid-term follow-up. The purpose of this systematic review and meta-analysis was to synthesize and critically appraise the literature on the long-term outcomes of shaft osteotomies of the first metatarsal (M1) to treat HV without inflammatory disease or degenerative arthritis, and to assess the long-term HV recurrence rates of studies with a minimum follow-up of 5 years. Methods: This systematic review conforms to the PRISMA guidelines. The authors conducted a search using PubMed, Embase®, and Cochrane Central Register of Controlled Trials databases. Studies that report outcomes of shaft osteotomies of the M1 for non-inflammatory and non-degenerative HV having a minimum follow-up of 5 years were included. We found five eligible studies comprising six datasets, all assessed Scarf osteotomies with a mean follow-up that ranged from 8 to 14 years. Results: The HV recurrence rate was 40%, considering the threshold of >15° hallux valgus angle (HVA), 30% having >20°, and 2% having >25°. Conclusion: At a minimum follow-up of 8 years following shaft osteotomies of M1, the HVA was 15.9°, the intermetatarsal angle (IMA) was 7.7°, and the DMAA was 8.3°. Furthermore, the recurrence rates considering the various thresholds of HVA were: 40% having >15°, 20% having >20°, and 2% having >25°. Level of Evidence: Meta-analysis, Level IV.

Transferability of ecological forecasting models to novel biotic conditions in a long-term experimental study.

Ecological forecasting models play an increasingly important role for managing natural resources and assessing our fundamental knowledge of processes driving ecological dynamics. As global environmental change pushes ecosystems beyond their historical conditions, the utility of these models may depend on their transferability to novel conditions. Because species interactions can alter resource use, timing of reproduction, and other aspects of a species' realized niche, changes in biotic conditions, which can arise from community reorganization events in response to environmental change, have the potential to impact model transferability. Using a long-term experiment on desert rodents, we assessed model transferability under novel biotic conditions to better understand the limitations of ecological forecasting. We show that ecological forecasts can be less accurate when the models generating them are transferred to novel biotic conditions and that the extent of model transferability can depend on the species being forecast. We also demonstrate the importance of incorporating uncertainty into forecast evaluation with transferred models generating less accurate and more uncertain forecasts. These results suggest that how a species perceives its competitive landscape can influence model transferability and that when uncertainties are properly accounted for, transferred models may still be appropriate for decision making. Assessing the extent of the transferability of forecasting models is a crucial step to increase our understanding of the limitations of ecological forecasts.

Drivers of interspecific synchrony and diversity-stability relationships in floodplain fish communities.

Diversity and interspecific synchrony are among the main drivers behind the temporal stability of community abundance. Diversity can increase stability through the portfolio effect, while higher synchrony generally decreases stability. In turn, species interactions and similar responses to environmental variation are considered the main factors underlying the strength of interspecific synchrony, despite the challenges in determining their relative roles. The analysis of the relationship between interspecific synchrony and the trait (or phylogenetic) distance between species can increase the robustness of inferences about these factors. Here, we used pairwise interspecific and community-wide analyses to investigate, respectively, the drivers of interspecific synchrony and the influence of trait and phylogenetic diversity on the stability of fish communities. For that, we used 18 years of fish abundance data from the Upper Paraná River floodplain. At the interspecific level, we used quantile regressions to test within-guild relationships between interspecific synchrony and trait and phylogenetic distance between species. At the community level, we tested the relationships between community-wide synchrony, stability, and (trait and phylogenetic) diversity. We found that interspecific synchrony decreased with trait and phylogenetic distances. In the community-level analysis, we found that more synchronous fish communities were less stable, but the relationship between diversity and stability was in general weak. At the interspecific level, our study highlights the role of similar responses to environmental variation in driving species' temporal dynamics. At the community level, the strength of the relationships between trait or phylogenetic diversity and community stability depended on the feeding guild. On the other hand, we found strong relationships between synchrony and stability. These results suggest that increased synchrony levels in response to regional environmental changes could decrease the stability of fish communities in this floodplain.
