Abstract
Head and neck cancers (HNCs) rank as the sixth most common cancer globally and result in over 450 000 deaths annually. Despite considerable advancements in diagnostics and treatment, the 5-year survival rate for most types of HNCs remains below 50%. Poor prognoses are often attributed to tumor heterogeneity, drug resistance, and immunosuppression. These characteristics are difficult to replicate using in vitro or in vivo models, culminating in few effective approaches for early detection and therapeutic drug development. Organs-on-a-chip offer a promising avenue for studying HNCs, serving as microphysiological models that closely recapitulate the complexities of biological tissues within highly controllable microfluidic platforms. Such systems have gained interest as advanced experimental tools to investigate human pathophysiology and assess therapeutic efficacy, providing a deeper understanding of cancer pathophysiology. This review outlines current challenges and opportunities in replicating HNCs within microphysiological systems, focusing on mimicking the soft, glandular, and hard tissues of the head and neck. We further delve into the major applications of organ-on-a-chip models for HNCs, including fundamental research, drug discovery, translational approaches, and personalized medicine. This review emphasizes the integration of organs-on-a-chip into the repertoire of biological model systems available to researchers. This integration enables the exploration of unique aspects of HNCs, thereby accelerating discoveries with the potential to improve outcomes for HNC patients.

Abstract
Background Saliva secretion and oral microbiota change in rhythm with our biological clock. Dysbiosis of the oral microbiome and alcohol consumption have a two-way interactive impact, but little is known about whether the oral microbiome undergoes diurnal changes in composition and function during the daytime in patients with alcohol dependence (AD). Methods The impact of alcohol consumption on the diurnal salivary microbiome was examined in a case-control study of 32 AD patients and 21 healthy control (HC) subjects. We tested the changes in microbial composition and individual taxon abundance by 16S rRNA gene sequencing. Results The present study is the first report showing that alcohol consumption enhanced the richness of the salivary microbiome and lowered the evenness. The composition of the oral microbiota changed significantly in alcohol-dependent patients. Additionally, certain genera were enriched in the AD group, including Actinomyces, Leptotrichia, Sphaerochaeta and Cyanobacteria, all of which have pathogenic effects on the host. There is a correlation between liver enzymes and oral microbiota. KEGG function analysis also showed obvious alterations during the daytime. Conclusion Alcohol drinking influences diurnal changes in the oral microbiota, leading to flora disturbance and related functional impairment. In particular, the diurnal changes of the oral microbiota may open avenues for potential interventions that can relieve the detrimental consequences of AD.

Abstract
BACKGROUND To study changes in the morphological structures and enzymatic activity of the submandibular salivary gland (SMG) and parotid salivary gland (PG) in rats after prolonged alcohol intoxication. METHODS Sexually mature male Wistar rats consumed 20% ethanol (6.9 g/kg/day) for 180 consecutive days. The PG and SMG were collected for morphometric and histochemical analyses (nonparametric Mann-Whitney U test, p < 0.05). RESULTS After exposure to ethanol for 180 days, the PG showed a change in the shape of the acini and the secretory cells that formed them, uneven expansion of the interlobular excretory ducts, and moderate fatty infiltration in the stroma. After exposure to ethanol for 180 days, the SMG showed fatty infiltration and stromal edema, and changes in acinar cells, intercalated ducts, and striated ducts. There was a significant decrease in the relative and absolute weight of the SMG. The number of mast cells in the PG and SMG and their degranulation index increased 2-fold after exposure to ethanol. All mast cells were highly active. After ethanol exposure, the activity of alkaline phosphatase increased significantly in the myoepithelial cells of the SMG and PG; the activity of NADPH oxidase increased only in the acini SMG, and the activity of succinate dehydrogenase remained at the control level in the acini of both glands. In the ducts of these glands, the activity of other enzymes did not change. CONCLUSIONS Changes in the morphological structures, morphometric parameters, and enzymatic activity of the rat salivary glands after 180 days of ethanol intoxication are shown for the first time. The most pronounced changes were found in the SMG.

Abstract
INTRODUCTION Oral epithelial dysplasia is considered a potential histologic precursor of subsequent squamous cell cancer. As standard clinical practice, pathologists grade dysplasia to assess risk for progression to malignancy. Except for the most advanced grade, severe dysplasia, dysplasia grading has failed to correlate well with the risk to develop invasive cancer. The questions of what process dysplasia grading best represents and what clinical utility dysplasia grading may have are explored. AREAS COVERED This narrative review is based on PubMed search with emphasis on papers since 2010. Epithelial dysplasia as a precursor lesion of cancer and dysplasia grading as a risk assessment tool for progression to cancer are discussed. The close clinical association of dysplasia with known carcinogens, alcohol, and tobacco products is presented. EXPERT OPINION Oral epithelial dysplasia is often, associated with prolonged exposure to tobacco and alcohol products. With reduction of carcinogen exposure, dysplasia is known to regress in some cases. It is proposed that histologic dysplasia grade together with macroscopic images of dysplastic clinical lesions be used as an educational tool to incentivize patients to reduce their known carcinogen exposure. This strategy has the potential to reduce lesion progression thereby reducing the disease burden of oral cancer.

Abstract
The emergency caused by Covid-19 pandemic raised interest in studying lifestyles and comorbidities as important determinants of poor Covid-19 prognosis. Data on tobacco smoking, alcohol consumption and obesity are still limited, while no data are available on the role of e-cigarettes and heated tobacco products (HTP). To clarify the role of tobacco smoking and other lifestyle habits on COVID-19 severity and progression, we designed a longitudinal observational study titled COvid19 and SMOking in ITaly (COSMO-IT). About 30 Italian hospitals in North, Centre and South of Italy joined the study. Its main aims are: 1) to quantify the role of tobacco smoking and smoking cessation on the severity and progression of COVID-19 in hospitalized patients; 2) to compare smoking prevalence and severity of the disease in relation to smoking in hospitalized COVID-19 patients versus patients treated at home; 3) to quantify the association between other lifestyle factors, such as e-cigarette and HTP use, alcohol and obesity and the risk of unfavourable COVID-19 outcomes. Socio-demographic, lifestyle and medical history information will be gathered for around 3000 hospitalized and 700-1000 home-isolated, laboratory-confirmed, COVID-19 patients. Given the current absence of a vaccine against SARS-COV-2 and the lack of a specific treatment for COVID-19, prevention strategies are of extreme importance. This project, designed to highly contribute to the international scientific debate on the role of avoidable lifestyle habits on COVID-19 severity, will provide valuable epidemiological data in order to support important recommendations to prevent COVID-19 incidence, progression and mortality.

Effects of cachaça, a typical Brazilian alcoholic beverage, on submandibular glands of rats: a histomorphometric and biochemical study. Clin Oral Investig 2020; 24:4283-4290. [PMID: 32356210 DOI: 10.1007/s00784-020-03290-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Accepted: 04/14/2020] [Indexed: 12/11/2022]
Abstract
OBJECTIVE This study aimed to evaluate the effects of chronic consumption of cachaça, a Brazilian beverage containing alcohol, on submandibular glands (SM) of rats by using histomorphometric and biochemical parameters. MATERIALS AND METHODS Twenty-four male rats (40 days of age) were assigned into the following four groups (n = 6): two control groups for 75 days (C75) and 105 days (C105), and two experimental groups of cachaça ingestion with ascending concentrations for consecutive 75 days (CA75) and 105 days (CA105). On the right SM glands, the striated, granular and acini ducts were processed for histomorphometric analysis. The left SM glands were weighed and stored at - 80 °C, to evaluate through biochemical tests carried out by spectrophotometric methods, the functional activity of total acid phosphatase (TAP), tartrate-resistant acid phosphatase (TRAP), and alkaline phosphatase (ALP) and to determine the mucin levels. RESULTS The absolute and relative weights of the SM glands in both experimental groups were reduced in relation to the controls (p < 0.05). The histomorphometric analysis showed a significant reduction of the acini area (p < 0.05) and non-relevant reduction of striated ducts (p > 0.05). The granular ducts did not show a significant increase of the area (p > 0.05). The TAP and TRAP activities were significantly decreased in the experimental groups (p < 0.05), while the ALP functional activity decreased moderately (p > 0.05). Mucin levels also had a significant reduction when compared with the control groups (p < 0.05). CONCLUSIONS Chronic consumption of cachaça can cause morphological changes associated with glandular atrophy, loss of biochemical functionality of phosphatases, and the reduction of mucin synthesis. CLINICAL RELEVANCE The consumption of cachaça can compromise the functions of the submandibular glands by altering their morphology and enzymatic activity.

Abstract
PURPOSE The purpose of this study was to investigate the influence of blade width and magnetic field strength on apparent diffusion coefficient values of periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) diffusion-weighted imaging in the head and neck at 1.5 and 3.0 T magnetic resonance imaging. METHODS Fifteen healthy volunteers (eight men and seven women; mean age 36.4 ± 10.1 years) underwent PROPELLER diffusion-weighted imaging using four blade widths at 3.0 T and three blade widths at 1.5 T. For the multigroup comparison of apparent diffusion coefficient values, we performed analysis of variance and Tukey-Kramer tests. The apparent diffusion coefficient values in each organ were compared among the different blade widths and magnetic field strengths by a t test. Inter and intra-observer agreements regarding apparent diffusion coefficient value measurements were evaluated using the intraclass correlation coefficient. RESULTS No significant differences were observed in apparent diffusion coefficient values of the cerebellum in each blade width at both field strengths. The apparent diffusion coefficient values of the right parotid glands were significantly lower for blade width 32 than for blade width 16 at 3.0 T (1.16 × 10-3 mm2/s vs. 1.01 × 10-3 mm2/s; P < 0.05). The apparent diffusion coefficient values of bilateral parotid glands were significantly higher at 1.5 T than at 3.0 T. Intraclass correlation coefficients were almost perfect to substantial in the cerebellum, whereas they showed moderate agreement in the parotid glands. CONCLUSION The largest blade width 32 at 3.0 T and high magnetic field strength lowered the apparent diffusion coefficient values of parotid glands of PROPELLER diffusion-weighted imaging. The apparent diffusion coefficient values in the parotid glands of PROPELLER diffusion-weighted imaging may be affected for blade width and magnetic field strength.

Abstract
We examined systemic medical and demographic characteristics of patients diagnosed with salivary malignant tumors in order to better understand the pathogenesis of the disease. Of 101 patients who received definitive treatment for malignant salivary gland tumors in our medical center, 22 died with disease (DwD) and were compared with the remaining 79 patients (Other). Mean ages were 66.7 years (median 68.0) in DwD group and 58.7 years (median 59.0) in the Others. The difference is significant (p = 0.037). Mucoepidermoid carcinoma was the diagnosis in 27.3% of DwDs and 27.8% of the others, Adenoidcystic carcinoma in 36.4% vs 21.5%, SCC and Acinic cell carcinoma were diagnosed in 18.3% vs 7.6% and 4.6% vs 7.6%, respectively. Alcohol consumption, concomitant malignancies, and chronic illnesses other than hypertension, were similar in the two groups, but hypertension (63.6%) in the DwD group was significantly higher than in the Other group (26.6%), (p = 0.0010). Smoking was also significantly different between the two groups: 50% of the DwD vs. 27.9% of the Others group smoked cigarettes. Similar distribution of the various malignant tumors in both groups emphasizes the relative importance of systemic factors such as smoking, aging and hypertension, in the salivary carcinogenesis process.

Abstract
BACKGROUND HIV research in Vietnam has focused primarily on its large heroin injector population. Data on men who have sex with men [MSM], particularly the large and growing population of men who exchange sex for money or other material rewards, male sex workers [MSWs], is very limited. METHODS Data derive from a cross-sectional study of MSW, age 16-35, recruited using community sampling methods in three cities in 2010-2011, including Hanoi, Ho Chi Minh City [HCMC], and Nha Trang City (n=710). Assessments included demographic characteristics, substance use, sexual risk, and use of health services. A series of "event" questions were used to assess the influence of alcohol and drugs on sexual risk. RESULTS Both tobacco and alcohol are initiated at a young age and most participants currently use both substances overall across all three cities. While alcohol and tobacco use precede the initiation of sex work, stimulant and opiate use are initiated following the initiation of sex work. There was substantial overlap between substance use and sexual risk, and this overlap was strongest in sexual events involving male and female elective partners rather than sex work clients. CONCLUSION Although rates of HIV infection in this group are low, this may be an artifact of the young age of the sample. High rates of drug use, including alcohol, tobacco and illicit drugs, coupled with high rates of ulcerative STIs such as HPV, suggest the potential for rapid amplification of STI/HIV risk among MSW and their complex sex partnering networks.

Abstract
The study analyzed the effects of chronic alcohol ingestion on the ultrastructure of the lining epithelium of the hard palatine mucosa of rats UChA and UChB (lines with voluntary alcohol consumption) in order to contribute to the understanding of the consequences of alcohol abuse for the morphology of the digestive system. Thirty female adult animals aged 120 days were divided into three experimental groups. (1) Ten UChA rats (genetically low ethanol consumer) with voluntary intake of 10% v/v (5.45 g/kg/day) ethanol solution and water. (2) Ten UChB (genetically high ethanol consumer) rats with voluntary intake of 10% v/v (7.16 g/kg/day) ethanol solution and water. (3) Ten Wistar rats with voluntary ad libitum water intake (control group). Both groups received Nuvital pellets ad libitum. The IGFR-I expression was intense in both experimental groups. The epithelial cells of the alcoholic rats UChA and UChB showed many alterations such as the presence of lipid droplets, altered nuclei, nuclei in corneum layer and disrupted mitochondria. It was concluded that ethanol intake induces ultrastructural lesions in the hard palatine mucosa.

Abstract
Alcohol consumption in the older adult is of major concern with the advent of baby boomers coming into the over 65-age bracket. Alcohol consumption has been touted as beneficial for health, and while that may be accurate for moderate consumption in younger persons, there is considerable risk associated with increased alcohol intake in older adults. This increase is partially due to age-related physiological changes, existing diagnoses, number of comorbid conditions, and increased use of prescribed and/or over-the-counter medications, coupled with other concerns. This review addresses the current research regarding ethanol consumption in older adults and all-cause mortality as well as several conditions more frequently seen in the geriatric population. These conditions include vascular diseases, hypertension, type 2 diabetes, gastrointestinal disorders, hepatic disorders, dental and oro-facial problems, bone density decline, and falls and fractures. In addition, drug interactions and recent research into select vitamin and mineral considerations with increased alcohol intake in older persons are addressed. While recommendations for alcohol intake have not been specifically established for age ranges within the 65-year-and-older bracket, and practitioners do not routinely assess alcohol intake or ethanol related adverse events in this population, common sense approaches to monitoring will become increasingly important as the generation of "boomers" who believe that alcohol intake improves health comes of age.

Abstract
Head and neck neoplasia can affect certain fundamental functions, including eating, drinking, speaking and respiration. One overriding factor in deciding on treatment policy is the tendency for head and neck malignancy to be limited to the primary site and regional lymph nodes with surgery and chemotherapy and radiotherapy. The aim of the study was to analyze the occurrence of Head and Neck tumours operated at ENT clinic Tuzla, University Clinical Center Tuzla, Bosnia and Herzegovina. Medical records of patients with histopathologically confirmed head and neck malignancies over a 5 year period (2003-2007) were analyzed. Eight hundred and eight one (881) cases, made up of 519 (58,8%) males and 362 (41,1%) females were found. The most common sites for head and neck malignancies were found to be in the larynx (26,1%), oral cavity (21,7%), the thyroid gland (14,64 %) and the neck (8,51%). A total of 230 patients were diagnosed with laryngeal carcinoma (M:173; F:57), showing the increasing number of female patients. The histopathological tumour types found in this work were mostly squamous cell carcinoma (72,09%), papillary carcinoma (12,2%), while many other minor histopathological variants accounted for 13%. The most patients were presented with stage I and stage III of disease (27% and 28,3%), and 19,9% with stage IV. About 40% of patients did not have data about smoking habit and alcohol drinking. The incidence of head and neck tumours seems to be relatively high, but without significant increase during investigated period. More investigation concerning risk factors, diagnostic procedures, and management strategies should be done in future.

Abstract
Alcohol dependence (AD) and, more generally, alcohol use disorders (AUDs) predispose individuals to adverse consequences that extend beyond the expected damage from alcohol-direct toxicity. Research has shown that the relationship of alcohol use to health outcomes is complex, as is the etiology of AD, and that the individual and social costs of alcohol-related problems are increasing. We review advances in alcohol science that explore the role of alcohol consumption and patterns of drinking in a range of medically comorbid conditions. Although new knowledge can assist in the development of appropriate medical management strategies, AUDs account for an important percentage of the global burden of disease and require approaches that are not uniquely focused on the identification and treatment of AD.
