INTRODUCTION: Plantar fasciitis (PF) is one of the most common running-related injuries. PURPOSE: The aim of this prospective study was to determine the incidence of PF and identify potential risk or protective factors for PF in runners and non-runners. METHODS: Data from 1206 participants from the 4HAIE cohort study (563 females/643 males; 715 runners/491 non-runners; 18-65 yr of age) were included in the analysis. We collected biomechanical data during overground running using a three-dimensional motion capture system at the baseline and running distance data via retrospective questionnaires and followed the participants for 12 months following the baseline data collection. Participants were asked weekly about any sports-related injury (including PF). A binary logistic regression was performed to reveal potential associations between running distance and biomechanical risk factors and PF while controlling for running distance, sex, and age. RESULTS: The total incidence of PF was 2.3% (28 PF from 1206 participants), 2.5% in runners and 2.0% in non-runners ( P = 0.248). Runners who ran more than 40 km·wk -1 had six times higher odds of suffering PF than individuals who ran 6-20 km·wk -1 ( P = 0.009). There was a significant association between maximal ankle adduction and PF; that is, runners with a lower abduction angle during the stance period had higher risk of PF ( P = 0.024). No other biomechanical variables indicated significant associations with PF. CONCLUSIONS: Regular running with a moderate weekly volume and more toeing out of the foot relative to the shank may reduce the risk against PF in runners, which may be useful for researchers, runners, coaches, and health professionals to minimize PF injury risk.

Pancreatic cancer (PC), particularly pancreatic ductal adenocarcinoma (PDAC), is a significant global health issue with high mortality rates. PDAC, though only 3 % of cancer diagnoses, causes 7 % of cancer deaths due to its severity and asymptomatic early stages. Risk factors include lifestyle choices, environmental exposures, and genetic predispositions. Conditions like new-onset type 2 diabetes and chronic pancreatitis also contribute significantly. Modifiable risk factors include smoking, alcohol consumption, non-alcoholic fatty pancreatic disease (NAFPD), and obesity. Smoking and heavy alcohol consumption increase PC risk, while NAFPD and obesity, particularly central adiposity, contribute through chronic inflammation and insulin resistance. Refined sugar and sugar-sweetened beverages (SSBs) are also linked to increased PC risk, especially among younger individuals. Hormonal treatments and medications like statins, aspirin, and metformin have mixed results on PC risk, with some showing protective effects. The gut microbiome influences PC through the gut-pancreas axis, with disruptions leading to inflammation and carcinogenesis. Exposure to toxic substances, including heavy metals and chemicals, is associated with increased PC risk. Glycome changes, such as abnormal glycosylation patterns, are significant in PDAC development and offer potential for early diagnosis. Interactions between environmental and genetic factors are crucial in PDAC susceptibility. Genome-wide association studies (GWAS) have identified several single nucleotide polymorphisms (SNPs) linked to PDAC, but gene-environment interactions remain largely unexplored. Future research should focus on polygenic risk scores (PRS) and large-scale studies to better understand these interactions and their impact on PDAC risk.

OBJECTIVES: Elderly hospitalized patients with inflammatory bowel disease (IBD) flare and concurrent Clostridioides difficile infection (CDI) are considered at high risk of IBD-related complications. We aimed to evaluate the short-,intermediate-, and long-term post-discharge complications among these patients. METHODS: A retrospective multicenter cohort study assessing outcomes of elderly individuals (≥60 years) hospitalized for an IBD flare who were tested for CDI (either positive or negative) and discharged. The primary outcome was the 3-month post-discharge IBD-related complication rates defined as steroid dependency, re-admissions (emergency department or hospitalization), IBD-related surgery, or mortality. We assessed post-discharge IBD-related complications within 6 month and mortality at 12 month among secondary outcomes. Risk factors for complication were assessed by multivariable logistic regression. RESULTS: In a cohort of 654 patients hospitalized for IBD {age 68.9 (interquartile range [IQR]): 63.9-75.2 years, 60.9% ulcerative colitis (UC)}, 23.4% were CDI-positive. Post-discharge complication rates at 3 and 6 months, and 12 months mortality, did not differ significantly between CDI-positive and CDI-negative patients (32% vs 33.1%, p = 0.8; 40.5% vs 42.5%, p = 0.66; and 4.6% vs 8%, p = 0.153, respectively). The Charlson comorbidity index was the only significant risk factor for complications within 3 months (aOR 1.1), whereas mesalamine (5-aminosalicylic acid [5-ASA]) use was protective (aOR 0.6). An UC diagnosis was the sole risk factor for complication at 6 months (aOR 1.5). Clostridioides difficile infection did not significantly impact outcomes or interact with IBD type. CONCLUSIONS: In elderly IBD patients hospitalized for IBD flare and subsequently discharged, a concurrent CDI infection was not associated with post-discharge IBD-related complications or mortality up to 1 year.

BACKGROUND: Anastomotic leakage is a significant complication following bowel resection in cytoreductive surgery for ovarian cancer. Previous studies have highlighted the detrimental effects of anastomotic leakage on patients' postoperative course. However, there is still a lack of precise identification of the high-risk population and established strategies for preventing its occurrence. MATERIALS AND METHODS: Patients who underwent bowel resection within the surgical phase III trial AGO-OVAR.OP3/LION investigating the impact of systematic pelvic and paraaortic lymphadenectomy in cytoreductive surgery for primary ovarian cancer were included in this analysis. All patients in the AGO-OVAR.OP3/LION trial had undergone complete cytoreduction with no macroscopic residual disease. We analyzed the occurrence of anastomotic leakage regarding surgical procedure (non-lymphadenectomy vs. lymphadenectomy and non-stoma vs. stoma) using the Fisher test. Risk factors for anastomotic leakage and its prognostic impact on survival were analyzed. RESULTS: Overall rate of anastomotic leakage was 7.1%. Notably, the Non-lymphadenectomy subgroup had a lower anastomotic leakage rate of 3.0% compared to the lymphadenectomy subgroup (11.2%, P = 0.005). The use of protective stoma placement resulted in an anastomotic leakage rate of 5.5% regardless of lymphadenectomy compared to the Non-Stoma subgroup (7.5%, P = 0.78). Increased blood loss (odds ratio [OR] 1.04 per 100cc, 95% confidence interval [CI] 1.0001-1.09) and lymphadenectomy (OR 3.67, 95% CI 1.41-11.40) were associated with a higher risk of anastomotic leakage. Although anastomotic leakage demonstrated a numerical detrimental impact on median progression-free survival (PFS) (18 months with anastomotic leakage vs. 19 months with Non-anastomotic leakage, hazard ratio [HR] 0.86; 95% CI 0.5 to 1.4, P = 0.53) and median overall survival (OS) (31 months with anastomotic leakage vs. 58 months with Non-anastomotic leakage, HR 0.69; 95% CI 0.4 to 1.2, P = 0.17), the differences were not statistically significant. CONCLUSION: Anastomotic leakage rates were lower in the Non-lymphadenectomy arm, the current standard of care. Blood loss and lymphadenectomy, as surrogate markers for extensive surgery, were associated with increased risk for anastomotic leakage. These findings highlight the importance of strategies to reduce surgical complexity and perioperative risk to improve clinical outcomes.

BACKGROUND: Neuromyelitis optica spectrum disorder (NMOSD) can be categorised into aquaporin-4 antibody (AQP4-IgG) NMOSD or seronegative NMOSD. While our knowledge of AQP4-IgG NMOSD has evolved significantly in the past decade, seronegative NMOSD remains less understood. This study aimed to evaluate the predictors of relapses and treatment responses in AQP4-IgG NMOSD and seronegative NMOSD. METHODS: This was a multicentre, international, retrospective cohort study using the MSBase registry. Recurrent relapse risk was assessed using an Andersen-Gill model and risk of first relapse was evaluated using a Cox proportional hazards model. Covariates that putatively influence relapse risk included demographic factors, clinical characteristics and immunosuppressive therapies; the latter was assessed as a time-varying covariate. RESULTS: A total of 398 patients (246 AQP4-IgG NMOSD and 152 seronegative NMOSD) were included. The AQP4-IgG NMOSD and seronegative NMOSD patients did not significantly differ by age at disease onset, ethnicity or annualised relapse rate. Both low-efficacy and high-efficacy immunosuppressive therapies were associated with significant reductions in recurrent relapse risk, with notably greater protection conferred by high-efficacy therapies in both AQP4-IgG NMOSD (HR 0.27, 95% CI 0.15 to 0.49, p<0.001) and seronegative NMOSD (HR 0.21, 95% CI 0.08 to 0.51, p<0.001). Longer disease duration (HR 0.97, 95% CI 0.95 to 0.99, p<0.001) and male sex (HR 0.52, 95% CI 0.34 to 0.84, p=0.007) were additional protective variables in reducing the recurrent relapse risk for the AQP4-IgG NMOSD group. CONCLUSION: Although further studies are needed to improve our understanding of seronegative NMOSD, our findings underscore the importance of aggressive treatment with high-efficacy immunotherapies in both NMOSD subtypes, regardless of serostatus.

Tick-borne encephalitis virus (TBEV) infection can manifest as disease of variable severity, ranging from subclinical infection to severe disease with neurological involvement and potentially fatal outcome. Although TBE is recognized as a major public health problem in Europe, the true burden of disease is potentially underestimated. Here, we investigated TBEV-specific antibody prevalence, infection incidence, and seroreversion and antibody decline rates in a prospective Swiss healthcare worker (HCW) cohort. We screened serum samples from 1444 HCWs between June and October 2020, and from a subset again between August and September 2021, using a TBEV envelope (E) protein IgG ELISA. Positive samples underwent further analysis with a TBEV non-structural protein 1 (NS1) IgG ELISA, and seroconversions in unvaccinated individuals were confirmed by seroneutralization testing. Questionnaire data were used to determine vaccination status and risk factors. TBEV E protein-specific IgG prevalence was 72.1% (95% CI 68.2-75.7%) in TBEV-vaccinated and 6% (95% CI 4.4-7.8%) in unvaccinated individuals. The estimated annual incidence of infection was 735/100,000. Age was the only factor significantly associated with seroprevalence. The seroreversion rate in unvaccinated individuals was 30.3% within one year, which is almost ten times higher than in vaccinated individuals (3.4%, annual decline rate 8.0%). NS1-specific IgG antibodies were six times more common in vaccinated than unvaccinated HCWs. In conclusion, undetected TBEV infections are common, and infection incidence is much higher than reported clinical cases. Individuals with abortive infections have high antibody decline and seroreversion rates. Whether lifelong protection is conferred and by which immune subsets remain unclear.

Vaccines represent an essential tool for the prevention of infectious diseases. Upon administration, a complex interaction occurs between the vaccine formulation and the recipient's immune system, ultimately resulting in protection against disease. Significant variability exists in individual and population responses to vaccination, and these differences remain the focus of the ongoing research. Notably, well-documented factors, such as age, gender, and genetic predisposition, influence immune responses. In contrast, the effects of overweight and obesity have not been as thoroughly investigated. The evidence indicates that a high body mass index (BMI) constitutes a significant risk factor for infections in general, with adipose tissue playing a crucial role in modulating the immune response. Furthermore, suboptimal levels of vaccine seroconversion have been observed among individuals with obesity. This review provides a plausible examination of the immunity and protection conferred by various vaccines in individuals with an overweight status, offering a comprehensive analysis of the mechanisms to enhance vaccination efficiency.

INTRODUCTION: Threats to our survival are often posed by the environment in which humans have evolved or live today. Animal and human ancestors developed complex physiological and behavioral response systems to cope with two types of threats: immediate physical harm from predators or conspecifics, triggering fear, and the risk of infections from parasites and pathogens leading to the evolution of the behavioral immune system (BIS) with disgust as the key emotion. Here we ask whether the BIS has adapted to protect us from pandemic risks or poisoning by modern toxic substances. METHODS: We have developed a survey comprised of 60 vignettes describing threats evoking fear and disgust belonging to one of the three main categories of threats: (1) ancestral, (2) modern, and (3) pandemic of airborne disease. Each vignette was evaluated on a 7-point Likert scale based on fear, disgust, and anger. Respondents also completed an assessment battery. RESULTS: The results show that the strongest fear is triggered by modern threats (electricity, car accidents), while the highest disgust is evoked by ancient threats (body waste products, worms). Disgust does not respond to modern threat stimuli such as toxic substances or radioactivity as these evoke mainly fear and anger. A discriminant factor analysis classified nine out of 10 pandemic disgust vignettes into the ancestral disgust category, convincingly assigning the pandemic disgust threats to the ancestral type. Gender, age, and type of education were significant moderators of emotional responses across all threat categories. DISCUSSION: Our study reveals that while fear is more context-dependent, particularly triggered by modern threats, disgust operates on an evolutionarily hardwired basis, making it less effective against contemporary risks. Furthermore, disgust experienced during a pandemic outbreak is more closely aligned with ancestral disgust-related threats tapping into evolutionary ancient survival circuits of the BIS. However, as disgust declines with age, the brain must adaptatively shift the emotional processing from disgust to fear to protect older adults from contamination risks. Finally, our study reveals that pandemic fear is better predicted by specific behaviors rather than general anxiety, suggesting a need for new assessments.

Neoadjuvant immunotherapy represents a pioneering approach in the preoperative treatment of cancer, providing new strategies for tumor reduction and improved patient outcomes by modulating the immune response. This study investigated neoadjuvant immunotherapy using intratumoral administration of mannan-BAM, Toll-like receptor ligands, and anti-CD40 antibody (MBTA therapy) followed by surgery in murine models of MTT pheochromocytoma, B16-F10 melanoma, and 4T1 and E0771.lmb mammary carcinomas. In the MTT pheochromocytoma model, it was found that neoadjuvant MBTA therapy followed by surgery could prevent the development of distant metastases in 100% of treated animals, compared to a 60% mortality rate in the control group due to metastatic disease after surgery. These outcomes were achieved even in tumors three times larger than those in the control group. In the aggressive 4T1 model, neoadjuvant MBTA therapy resulted in slower tumor progression and a significant prolongation of survival. In the B16-F10 and E0771.lmb models, neoadjuvant MBTA therapy also protected animals from metastases development and tumor recurrence upon rechallenge with tumor cells after surgery. Transcriptomic analysis revealed enhanced effector immune cell infiltration, cytotoxicity, and antigen presentation in retransplanted tumors from MBTA-treated mice, indicating robust immune memory. Notably, the exclusion of the anti-CD40 antibody from the neoadjuvant MBTA therapy (MBT therapy) yielded comparable outcomes in protection against metastases development. These findings advocate for further investigation of intratumoral neoadjuvant MBTA therapy for immunologically "cold" tumors, including those at high risk of metastases or recurrence.

Zubní kaz (ZK) je jedno z nejčastějších chronických infekčních onemocnění dětského věku. Kromě nadměrného příjmu sacharidů a přítomnosti zubního mikrobiálního plaku se za další významné rizikové faktory vzniku ZK pokládá složení tvrdých zubních tkání a sliny. Slina odráží fyziologický a patologický stav dutiny ústní a hraje významnou roli při vzniku a prevenci zubního kazu. Možnými biomarkery zubního kazu je řada měřitelných vlastností sliny - množství sliny, pH sliny, pufrovací kapacita, přítomnost a množství kariogenních mikroorganismů. Hlavními složkami sliny jsou voda a různé anorganické a organické substance. Za významné organické látky se považují antimikrobiální peptidy, slinné glykoproteiny a proteiny s enzymatickou aktivitou. Tyto látky mohou sloužit jako zdroj biomarkerů pro stanovení rizika vzniku zubního kazu. Slinné biomarkery mohou být využity nejen pro predikci, diagnostiku, prognózu a ošetřování zubního kazu, ale i pro hodnocení výsledků léčení. Cílem dalších výzkumů bude charakterizovat vztahy mezi jednotlivými proteiny, jejich interakce a určit, jakým způsobem ovlivňují vznik a progresi zubního kazu.

Dental caries is one of the most common chronic infectious diseases of childhood. In addition to excessive sugar intake and presence of dental microbial plaque, other risk factors related to dental caries are the composition of hard dental tissues and saliva. Saliva can reflect the physiological and pathological state of the oral cavity and plays a crucial role in the initiation of dental caries and protection against dental caries. Many measurable characteristics of saliva are potential biomarkers for dental caries - salivary flow rate, salivary pH, buffering capacity, evaluation of the presence and amount of cariogenic bacteria. The major salivary components are water and various, inorganic and organic substances. The most important organic components of saliva comprise antibacterial peptides, salivary glycoproteins, salivary proteins and proteins with enzymatic activity. These substances can serve as a source of biomarkers for caries risk assessment. Salivary biomarkers may be exploited for the prediction, diagnosis, prognosis and management of dental caries, as well as for evaluating the outcome of therapeutic regimens. Future research is essential to characterize the interaction of salivary proteins, and determine how these affect the initiation and development of dental caries.
