BACKGROUND
A proportion of head and neck carcinomas (HNSCCs) are induced by high-risk human papillomaviruses (HPVs) and are associated with better patient outcomes compared to patients with HNSCCs related to tobacco and alcohol abuse. In the microenvironment of solid tumors, including HNSCCs, oxygen levels are often reduced, and a hypoxic state is induced. This can lead to a poor treatment response and a worse patient prognosis. One of the hypoxia-responsive genes is aspartate-β-hydroxylase (ASPH), whose activity promotes the growth, invasiveness, and metastasis of many types of solid tumors.
METHODS
In our study, HNSCC samples were analyzed for the expression of ASPH and selected endogenous hypoxia markers by real-time PCR and/or multiplex fluorescence immunohistochemistry.
RESULTS
Except for the EPAS1 gene, which had higher mRNA expression in the HPV-negative group of HNSCC (p < 0.05), we found no other differences in the expression of the tested genes that were related to HPV status. On the contrary, a statistically significantly higher number of cells producing ASPH (p < 0.0001), HIF1A (p < 0.0001), GLUT1 (p < 0.0001), and MMP13 (p < 0.05) proteins were detected in the HPV-positive tumor group than in the HPV-negative sample group. All the evaluated markers, except for MMP9/13, were more abundant in the tumor parenchyma than in the tumor stroma. The Cox proportional hazard models showed that increased numbers of cells with GLUT1 and HIF1A protein expression were positive prognostic markers for overall and disease-specific survival in patients independent of HPV tumor status.
CONCLUSION
The study examined HNSCC samples and found that elevated ASPH and hypoxia marker proteins, typically associated with poor prognosis, may actually indicate active HPV infection, the strongest prognostic factor in HNSCC patients. In cases where HPV status is uncertain, increased expression of HIF1A and GLUT1 can serve as positive prognostic factors.

Although previous studies point to a high mental health burden in veterinarians, little is known about mental health in Austrian veterinarians as well as potential underlying factors of poor mental health. We assessed mental health in Austrian veterinarians, compared it to the mental health of the general population, and explored potential risk factors for poor mental health in veterinarians. A total of n = 440 veterinarians (72.0% women; mean age: 44.53 ± 11.25 years) took part in an online survey in 2022 in which validated screening tools for symptoms of depression (PHQ-9), anxiety (GAD-7), sleep disorders (ISI-2), perceived stress (PSS-4), and alcohol abuse (CAGE) were applied. Multivariable logistic regression revealed higher adjusted odds for exceeding cut-offs for clinically relevant depressive, anxiety, and insomnia symptoms in veterinarians (1.35-2.70) compared to the general population. Mental health symptoms in veterinarians were associated with female gender, physical inactivity, higher smartphone usage, higher working hours, less professional experience, and working with pets. In conclusion, it appears that veterinarians encounter mental health challenges that are more pronounced than those experienced in the general population. The teaching of strategies to improve mental hygiene as part of the curricula of veterinary education and targeted training and mentoring of employers and their team should be implemented to improve mental health in the veterinary profession.

Review
Male breast cancer accounts for less than 1% of all breast cancer cases. The important risk factors for the development of male breast cancer are family history, genetic mutations, obesity, liver disease, alcoholism, exogenous estrogen administration, and radiation exposure to the chest area. Despite its rarity, numerous studies have investigated the data on imaging considerations (mammogram, ultrasound, and magnetic resonance imaging (MRI)), but have addressed only certain aspects of male breast cancer. A comprehensive approach on the imaging characteristics, timing of imaging, prognostication based on imaging characteristics, and follow-up strategies in male breast cancer are still lacking. The purpose of this review article was to provide a comprehensive overview of the imaging findings, optimal timing to obtain imaging, and the appropriate follow-up strategies in male breast cancer survivors. This article also describes how imaging modalities can aid in determining prognosis. By addressing this knowledge gap, the article provides valuable insights for clinicians managing this uncommon yet clinically significant disease.

INTRODUCTION
The risk of suicide and completed suicides among young university students presents critical challenges to mental and public health in Colombia and worldwide. Employing a quantifiable approach to comprehend the factors associated with these challenges can aid in visualizing the path towards anticipating and controlling this phenomenon.
OBJECTIVE
Develop a predictive model for suicidal behavior in university students, utilizing predictive analytics.
METHOD
We conducted an observational, retrospective, cross-sectional, and analytical research study at the University of Manizales, with a focus on predictive applicability. Data from 2,436 undergraduate students were obtained from the research initiative "Building the Future: World Mental Health Surveys International College Students."
RESULTS
The top ten predictor variables that generated the highest scores (ranking coefficients) for the sum of factors were as follows: history of sexual abuse (13.21), family history of suicide (11.68), medication (8.39), type of student (7.4), origin other than Manizales (5.86), exposure to cannabis (4.27), exposure to alcohol (4.42), history of physical abuse (3.53), religiosity (2.9), and having someone in the family who makes you feel important (3.09).
DISCUSSION
Suicide involves complex factors within psychiatric, medical, and societal contexts. Integrated detection and intervention systems involving individuals, families, and governments are crucial for addressing these factors. Universities also play a role in promoting coping strategies and raising awareness of risks. The predictive accuracy of over 80% in identifying suicide risk underscores its significance.
CONCLUSION
The risk factors related to suicidal behavior align with the findings in specialized literature and research in the field. Identifying variables with higher predictive value enables us to take appropriate actions for detecting cases and designing and implementing prevention strategies.

OBJECTIVES
Persistent olfactory dysfunction (OD) following loss of smell associated with SARS-CoV-2 infection is a major feature of long COVID. Perspectives on the prevalence of persistent OD predominantly rely on self-reported olfactory function. Few studies have tracked longitudinal rates of recovery using psychophysical assessment among patients presenting for evaluation of persistent OD beyond a window of acute recovery. Data anchored in standardized testing methods are needed to counsel patients who fail to acutely regain their sense of smell. This study aims to quantify the degree of persistent OD in post-COVID-19 patients who experience subjective and psychophysical OD.
METHODS
We grouped participants presenting for OD evaluation into cohorts based on both subjective and psychophysical olfactory status at a baseline assessment and assessed their olfactory abilities with a visual analogue scale and the Sniffin' Sticks extended test at baseline and 1-year time points. Participants had confirmed a history of COVID-19 by lab evaluation or clinical diagnosis if lab evaluation was not available.
RESULTS
Baseline olfactory evaluation was completed by 122 participants, 53 of whom completed the 1-year follow-up assessment. Among participants presenting with perceived OD, 74.5% had confirmed psychophysical OD at baseline, with 55.1% at 1-year follow-up. Participants had reliable trends in self-rated versus psychophysically tested olfactory function at both time points. The total threshold, discrimination, and identification (TDI) score improved by +3.25 points in the cohort with psychophysical OD ( = 0.0005), with this improvement largely attributable to an increase in median threshold scores (+2.75 points; = 0.0004).
CONCLUSIONS
OD persists in a significant number of patients who fail to acutely recovery their sense of smell after COVID-19, with many demonstrating lingering deficits at 1-year. Improvements in threshold, but not discrimination or identification, most significantly mediate improvement of total TDI score at follow-up.

BACKGROUND
The optimal duration and choice of antibiotic for fracture-related infection (FRI) is not well defined. This study aimed to determine whether antibiotic duration (≤6 vs >6 weeks) is associated with infection- and surgery-free survival. The secondary aim was to ascertain risk factors associated with surgery- and infection-free survival.
METHODS
We performed a multicenter retrospective study of patients diagnosed with FRI between 2013 and 2022. The association between antibiotic duration and surgery- and infection-free survival was assessed by Cox proportional hazard models. Models were weighted by the inverse of the propensity score, calculated with a priori variables of hardware removal; infection due to , , or species; and flap coverage. Multivariable Cox proportional hazard models were run with additional covariates including initial pathogen, need for flap, and hardware removal.
RESULTS
Of 96 patients, 54 (56.3%) received ≤6 weeks of antibiotics and 42 (43.7%) received >6 weeks. There was no association between longer antibiotic duration and surgery-free survival (hazard ratio [HR], 0.95; 95% CI, .65-1.38; = .78) or infection-free survival (HR, 0.77; 95% CI, .30-1.96; = .58). Negative culture was associated with increased hazard of reoperation or death (HR, 3.52; 95% CI, 1.99-6.20; < .001) and reinfection or death (HR, 3.71; 95% CI, 1.24-11.09; < .001). Need for flap coverage had an increased hazard of reoperation or death (HR, 3.24; 95% CI, 1.61-6.54; = .001).
CONCLUSIONS
The ideal duration of antibiotics to treat FRI is unclear. In this multicenter study, there was no association between antibiotic treatment duration and surgery- or infection-free survival.

Background Cancer is the leading cause of death globally. Information on cancer patterns and survival is essential for the effective planning and implementation of cancer control interventions. Objective This study aimed to identify various factors associated with the survival estimates of common cancers. Methods A community-based ambispective study was conducted in a rural population. Data were collected from individuals diagnosed with cancer or relatives of individuals who died of cancer. The total population covered was 82,983. All cancer cases diagnosed since 2005 and followed until the year 2020 were included. Survival analysis and five-year survival rates were estimated. A Cox proportional hazard model was used. Results A total of 146 cancer patients were included in the study. Five-year survival estimates for breast cancer, head and neck cancer, and GI cancer were 72%, 28%, and 0%, respectively. The median survival time was lowest for GI cancers (1 year), and for head and neck and breast cancers, it was 3 and 6 years, respectively. Multivariate Cox regression was performed, adjusting for age, type of hospital, alcohol use, tobacco use, opium use, gender, treatment sought, GI cancer, frequency of changing hospitals, and frequency of follow-up. After adjustment, changing hospitals ≥3 times, being lost to follow-up, receiving no treatment, tobacco abuse, and the presence of GI cancers were significantly associated with survival estimates. Conclusions The five-year survival estimate for GI cancers was the lowest compared to other cancers. Study participants who were lost to follow-up or who took no treatment were significantly associated with lower survival estimates.

Long-standing overt ventriculomegaly in adults (LOVA) is a kind of chronic hydrocephalus that has been reported to have started in infancy and is characterized by severe ventriculomegaly and macrocephaly. It often manifests clinically in later adulthood. We describe the case of a 34-year-old male patient who had a history of chronic alcoholism and who had been complaining of headaches, disturbed gait, and frequent falls for three months when he arrived in a stupor at the emergency room. Massive ventriculomegaly with Evans' index of 0.40 was found during a head magnetic resonance imaging (MRI). The MRI results were more severe than the clinical manifestations. He was diagnosed with LOVA and treated with conservative hyperosmolar drugs, neuroprotective agents, and intravenous (IV) thiamine. The patient was discharged and consented to follow-up after a hospital stay of seven days.

Preclinical and human studies indicate psilocybin may reduce perseverant maladaptive behaviors, including nicotine and alcohol seeking. Such studies in the opioid field are lacking, though opioids are involved in more >50% of overdose deaths. Psilocybin is an agonist at the serotonin 2A receptor (5-HTR), a well-documented target for modulation of drug seeking, and evidence suggests 5-HTR agonists may dampen motivation for opioids. We sought to investigate the therapeutic efficacy of psilocybin in mediating cessation of opioid use and maintenance of long-lasting abstinence from opioid seeking behavior in a rat model of heroin self-administration (SA). Psilocybin or 5-HTR antagonists ketanserin and volinanserin were administered systemically to rats prior to SA of 0.075 mg/kg/infusion of heroin, or relapse following forced abstinence. Psilocybin did not alter heroin taking, but a single exposure to 3.0 mg/kg psilocybin 4-24 hours prior to a relapse test blunted cue-induced heroin seeking. Conversely, 5-HTR antagonists exacerbated heroin relapse. To begin to elucidate mechanisms of psilocybin, drug-naïve rats received psilocybin and/or ketanserin, and tissue was collected from the prefrontal cortex (PFC), a region critical for drug seeking and responsive to psilocybin, 24 hours later for RNA-sequencing. 3.0 mg/kg psilocybin regulated ~2-fold more genes in the PFC than 1.0 mg/kg, including genes involved in the cytoskeleton and cytokine signaling. Ketanserin blocked >90% of psilocybin-regulated genes, including the IL-17a cytokine receptor, . Psychedelic compounds have reported anti-inflammatory properties, and therefore we performed a gene expression array to measure chemokine/cytokine molecules in the PFC of animals that displayed psilocybin-mediated inhibition of heroin seeking. Psilocybin regulated 4 genes, including , and a subset of genes correlated with relapse behavior. Selective inhibition of PFC IL-17a was sufficient to reduce heroin relapse. We conclude that psilocybin reduces heroin relapse and highlight IL-17a signaling as a potential downstream pathway of psilocybin that also reduces heroin seeking.

BACKGROUND
Alcohol dependence syndrome is a major public health problem, and it impacts the social, psychological, medical, economic, and religious spheres of our existence. Persistent alcohol abuse impacts sexual functioning negatively and leads to the onset of sexual dysfunction.
AIM
This study was conducted to determine erectile dysfunction in males diagnosed with alcohol dependence syndrome and its association with the severity of alcohol dependence.
MATERIALS AND METHODS
The descriptive, non-interventional, cross-sectional study was conducted at the Department of Psychiatry in a tertiary care hospital where 78 subjects diagnosed with alcohol dependence syndrome were assessed for severity of dependence with the Severity of Alcohol Dependence Questionnaire (SADQ-C). Erectile dysfunction in these subjects was assessed with the International Index of Erectile Function scale (IIEF) and the severity of the same was correlated with the severity of alcohol dependence.
RESULTS
The results of our study indicated that erectile dysfunction was common in individuals having alcohol dependence syndrome and its severity was positively correlated with the severity of alcohol dependence. Unidentified sexual dysfunction may perpetuate alcohol dependence with poor response to deaddiction therapy. This information about sexual dysfunction due to alcohol dependence can also be used in motivational counseling of heavy drinkers to provide an impetus for change.
CONCLUSIONS
The prevalence of erectile dysfunction was significantly higher than that of the general population. The same was significantly elevated in patients with severe alcohol dependence as compared to those with mild/moderate alcohol dependence.
