Effects of Temporomandibular Disorders on the Oral Hygiene Status and Oral Health-Related Quality of Life of Young Adults

Objective: This study aimed to provide basic data to develop effective measures to improve the oral hygiene and oral health-related quality of life of individuals by preventing temporomandibular disorders. Methods: Data were collected from 148 young adults who visited the Department of Dental Hygiene of K University in Region D for practical training. The collected data were subjected to independent sample t-test and Pearson’s correlation coefficient and logistic regression analyses. Results: Incidence of temporomandibular disorders and oral hygiene status were significantly negatively correlated with oral health-related quality of life, whereas that of temporomandibular disorders was significantly positively correlated with the oral hygiene status. Additionally, incidence of temporomandibular disorders was 3.821 times higher in the poor oral hygiene group than in the good oral hygiene group and 0.845 times lower in the good oral health-related quality of life group than in the poor oral healthrelated quality of life group. The explanatory power of these factors was 53.9%. Conclusions: These results suggest the importance of the prevention, early detection, and treatment of temporomandibular disorders to ensure good oral hygiene status and oral health-related quality of life of young adults. Furthermore, there is need for effective oral health education measures, including oral health projects for young adults, to prevent and treat temporomandibular joint disorders.

A comprehensive study on the autochthonous microbiota, volatilome, physico-chemical, and morpho-textural features of Montenegrin Njeguški cheese

The present study aims to deepen the knowledge of the microbiota, gross composition, physico-chemical and morpho-textural features, biogenic amines content and volatilome of Njeguški cheese, one of the most popular indigenous cheeses produced in Montenegro. Cheese samples were collected in duplicate from three different batches produced by three Montenegrin artisan producers. For the first time, the microbiota of Njeguški cheese was investigated using both culture-dependent techniques and metagenomic analysis. Coagulase positive staphylococci viable counts were below the detection limit of the analysis (<1 log cfu g−1). Salmonella spp., Listeria monocytogenes and staphylococcal enterotoxins were absent. However, relatively high viable counts of Enterobacteriaceae, Escherichia coli, Pseudomonadaceae and eumycetes were detected. Metataxonomic analysis revealed a core microbiome composed of Lactococcus lactis, Streptococcus thermophilus, Debaryomyces hansenii, and Kluyveromyces marxianus. Furthermore, the detection of opportunistic pathogenic yeasts such as Magnusiomyces capitatus and Wickerhamiella pararugosa, along with the variable content of biogenic amines, suggests the need for increased attention to hygienic conditions during Njeguški cheese production. Significant variability was observed in humidity (ranging from 38.37 to 45.58 %), salt content (ranging from 0.70 to 1.78 %), proteins content (ranging from 21.42 to 25.08 %), ash content (ranging from 2.97 to 4.05 %), hardness, springiness, and color among samples from different producers. Gas chromatography-mass spectrometry analysis showed a well-defined and complex volatilome profile of the Njeguški cheese, with alcohols (ethanol, isoamyl alcohol, phenetyl alcol), esters and acetates (ethyl acetate, ethyl butanoate, isoamyl acetate), ketones (acetoin, 2-butanone), and acids (acetic, butanoic, hexanoic acids) being the main chemical groups involved in aroma formation. This research will provide new insights into the still poorly explored identity of Njeguški cheese, thus serving as a first baseline for future studies aimed at protecting its tradition.

Assessment of the impact of locally fabricated oven and sun drying method on the proximate, mineral and microbiological composition of Clarias gariepinus (catfish)

Drying is an age long practice which prevent fish from deterioration and spoilage, however, traditional drying is usually practiced in rural settings with poor hygienic conditions, thus, the nutritional and microbial quality of such products is uncertain. Therefore, the present study was aimed at evaluating the impact of a locally fabricated oven and sun drying method on the proximate, mineral and microbial composition of Clarias gariepinus (Catfish) using standard laboratory procedures. The results of the proximate analysis showed that the oven dried fish had the highest crude protein content (66.43 ± 3.37 %), crude lipid content (8.27 ± 0.28 %) and carbohydrate content (4.50 ± 0.22 %) which were statistically significant (p&lt;0.05) when compared to the sun dried fish, while the sun dried fish had the highest ash content (16.30 ± 2.48 %) and moisture content (14.30 ± 0.82 %) which were statistically significant (p&lt;0.05) when compared to the oven dried fish. Also, the mineral analysis showed that the oven dried fish had the highest calcium (821.49 ± 1.10 mg/kg), phosphorus (86.04 ± 0.83 mg/kg), potassium (254.72 ± 0.40 mg/kg), iron (40.73 ± 0.23 mg/kg), manganese (0.95 ± 0.01 mg/kg) and selenium (14.15 ± 0.39 mg/kg) content which were statistically significant (p&lt;0.05) when compared to the sun dried fish, while the sun dried fish had the highest sodium (173.52 ± 0.12 mg/kg), cupper (0.87 ± 0.12 mg/kg), magnesium (39.01 ± 0.43 mg/kg) and zinc (2.83 ± 0.23 mg/kg) content which were also statistically significant (p&lt;0.05) when compared to the oven dried fish. The study also showed that the total viable bacterial count was higher in the sun dried fish (6.23 x 105 cfu/g) which was not statistically significant (p&lt;0.05) when compared to the oven dried fish (5.65 x 105cfu/g), while the fungal count was higher in the oven dried fish (6.55 x 105 cfu/g) which was also not statistically significant (p&lt;0.05) when compared to the sun dried fish (5.01 x 105 cfu/g). The findings in this study showed that the locally fabricated oven was remarkably effective, yielding fish with significantly enhanced nutritional profiles and minimal microbial contamination. This approach offers a superior method for fish preservation, providing a promising alternative for improving food safety and nutritional quality.

Oral Health Status and Barriers among Children with Cerebral Palsy in Maintaining Oral Hygiene: An Interventional Study

Abstract Context: Cerebral palsy is a neuromuscular disorder that hampers proper maintenance of oral hygiene leading to the development of periodontal diseases and progression of dental caries. Aim: The present study aimed to analyze the oral health status and barriers to maintaining oral hygiene among children with cerebral palsy using intervention (brushing technique). Materials and Methods: A total of 100 children diagnosed with cerebral palsy were selected from an academic institution for special needs children. The groups studied were: a) Group A with children aged between 6 and 10 years, b) Group B had children aged from 11 to 15 years, and c) Group C with children aged range from 16 to 18 years of age. Parental education level status was classified into a) Upper class (Code 1): Parents with a college education, b) Middle class (Code 2): Parents with education till secondary school level, and c) Lower class (Code 3): Parents with primary school level or no education. Oral examinations were performed using a mouth mirror, explorer, and torch light illumination to assess DMFT index (permanent dentition), DMFT index (primary dentition), and OHI-S for gingival and periodontal health. Fone’s technique for tooth brushing was demonstrated to children’s caregivers and/or parents. After this, an oral examination was conducted at the baseline and at three months. One-way ANOVA was used for statistical analysis using SPSS software. Result: Statistically significant improvement in dental caries index and oral hygiene status was seen following demonstration of proper brushing technique. Conclusion: The training of caregivers/parents helps in improving the oral hygiene status in cerebral palsy-affected children.

Discovery of a new volcanic soil material, "Akahoya," as an adsorbent for bacterial and viral pathogens and its application to environmental purification.

Akahoya is a volcanic soil rich in alumina, primarily deposited in Kyushu, Japan. We have found that Akahoya adsorbs bacteria in the water surrounding cattle grazing areas, suggesting a potential for environmental purification. This study investigated the spectrum of microorganisms adsorbed by Akahoya using a column filled with Akahoya through which a suspension of microorganisms was passed. Shirasu soil, another volcanic soil with a different chemical composition, was used as a control. Akahoya effectively adsorbed a diverse range of microorganisms including Escherichia coli, Campylobacter jejuni, Vibrio parahaemolyticus, Salmonella Enteritidis, Staphylococcus aureus, Clostridium perfringens, spores of Bacillus subtilis and Bacillus anthracis, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), murine norovirus, and avian influenza virus (H3N2), whereas Shirasu soil did not adsorb any of the organisms examined. Moreover, bacteria naturally present in river water, such as aerobic bacteria, total coliforms, and Enterobacteriaceae as indicators of river contamination, as well as E. coli added artificially to sterilized river water, were reduced to below the detection limit (<1 CFU/mL) after being passed through Akahoya. Additionally, the number of viable E. coli continued to decrease after contact with Akahoya for 1 month, suggesting bactericidal effects. Notably, the adsorption of E. coli to Akahoya was influenced by the concentration of phosphate and the pH of the suspension due to the interaction between the surface phosphorylation of organisms and Al2O3, the major chemical component of Akahoya. The present results demonstrate the remarkable ability of Akahoya to remove phosphate and microbes, suggesting that Akahoya could be used for water purification processes.IMPORTANCEAlthough a safe and sufficient water supply is essential for the maintenance of hygienic conditions, a major challenge is to develop a comprehensive effective, sustainable, and cost-effective technological approach for the treatment and purification of contaminated water. In this study, we demonstrated that a novel volcanic soil, Akahoya, which has unlimited availability, is a highly effective adsorbent for a wide range of bacterial and viral pathogens, suggesting its potential as a sustainable resource for this purpose. It was suggested that the adsorption of microorganisms on Akahoya was mediated by phosphate groups present on the surface structures of microorganisms, which bind to the alumina component of Akahoya according to the phosphate concentration and pH of the liquid phase. The present findings highlight the exceptional ability of Akahoya to eliminate or reduce phosphate and microorganisms effectively in water purification processes, thus contributing to the development of efficient and sustainable solutions for addressing water pollution challenges.

Bacterial growth in breast milk expressed under hygienic control: a pilot study

ObjectiveIn this pilot study, we verified safe practices for breast milk expression, storage, and duration, based on bacteriological results.ResultsWe collected breast milk samples from three healthy lactating volunteers and analyzed the bacterial flora and changes in the viable bacterial counts (including those of Staphylococcus) of the samples. Although no consistent change could be observed in the abundance of a particular bacterial group in samples expressed under hygienic control conditions, viable bacterial counts were higher in self-expressed milk than in milk expressed under hygienic control conditions. In conclusion, increased hygiene awareness is vital during breast milk expression and storage.

DNA Metabarcoding Approach as a Potential Tool for Supporting Official Food Control Programs: A Case Study.

Food authentication significantly impacts consumer health and the credibility of Food Business Operators (FBOs). As European regulations mandate the verification of food authenticity and supply chain integrity, competent authorities require access to innovative analytical methods to identify and prevent food fraud. This study utilizes the DNA metabarcoding approach on meat preparations, sampled during an official control activity. It assesses animal and plant composition by amplifying DNA fragments of the 12S rRNA and trnL (UAA) genes, respectively. The results not only confirmed the declared species but also revealed undeclared and unexpected taxa in products labelled as containing a single animal species and various unspecified plant species. Notable findings such as the presence of Murinae, Sus scrofa, Ovis aries, and Pisum sativum could raise public health concerns, compromise consumer choices made for ethical or religious reasons, and reflect the hygienic conditions of the processing plant. This study demonstrates that the DNA metabarcoding approach looks to be a promising support tool for official control authorities to ensure food authenticity and safety, and to develop risk profiles along the supply chain.

Post-war status of water supply, sanitation, hygiene and related reported diseases in Tigray, Ethiopia: A community-based cross-sectional study

Water, sanitation and hygiene (WASH) associated diseases remain a global public health issue and linked with Sustainable Development Goal 6. In November 2020, a war broke out in Tigray, Ethiopia, resulting in a negative health consequence. The post war status of WASH and its associated diseases are not documented. The aim of this study was to assess the status of drinking water, sanitation and hygiene practices and the prevalence of WASH-associated diseases in Tigray, Ethiopia following the war. A community-based cross-sectional study was conducted in 24 randomly selected accessible districts of Tigray, Ethiopia. A standardized questionnaire was used to collect data from households in the study. Data was collected from 2338 households. Descriptive statistics and binary logistic regression were used to analyze the data. The average age of respondents was 28.7 years (SD = 6.2). The majority of respondents 2030 (86.8%) were married and 1698 (72.6%) were rural residents. Nearly one third of the respondents were uneducated and around 40% have either radio or TV as means of communication. More than half (55.2%) of the respondents had a family size of over 5.A quarter (25%, 95% CI: 23.3, 26.8) of study participants had access to a basic water supply. Less than a tenth (7.7%, 95% CI: 6.6, 8.8) of households had access to basic sanitation. Basic hand washing was available in 2% of households. Malaria, diarrhoea, skin infection and eye infection were the common reported disease in the community. Marital status, family size, place of residence and liquid waste management were the most important predictors of reported diseases.Access to basic water, sanitation and hygiene services was low, and the prevalence of malaria, diarrhoea and skin infections was higher. There were differences in WASH services and reported diseases according to zone and place of residence (urban-rural). Post war, improved access to basic water, sanitation and hygiene services is recommended to prevent WASH-associated diseases in Tigray, Ethiopia. Furthermore, the prevention oriented policy of the country needs better implementation to reduce preventable diseases and ensure better health status in the community.

Monitoring foodborne pathogens of food served at an institutional cafeteria

The provision of food by cafeterias is an opportunity to promote health through a balanced diet and safe food, offering the prospect of sustainably developing the well-being a community and the local economy. This study assessed the hygiene conditions of an institutional cafeteria. The presence of foodborne pathogens and indicators of general hygiene in 143 food and environmental samples were analyzed using the TEMPO and VIDAS food safety testing machines. All food samples tested negative for Salmonella sp., and Staphylococcus aureus counts were below the GCC Standardization Organization (GSO) limit. Escherichia coli was detected at level above the set limit in six food samples. Sixteen food samples showed aerobic bacterial counts above the set limit. Total coliforms and Enterobacteriaceae were each detected above the set limits in eight food samples. Yeasts and molds were detected above the set limit in 14 food samples. Coliform bacteria, S. aureus, and mold were detected on the hands and white coats of cafeteria workers and on work surfaces, machines, and cutting boards. The hygiene conditions of the cafeteria are not suitable for food preparation, and to improve hygienic conditions in cafeterias, regular inspection of food and food preparation facilities is strongly recommended.

Application of the behaviour-centred design to understand facilitators and deterrents of hand hygiene among healthcare providers: findings from a formative phase of a cluster randomised trial in the Kampala Metropolitan area

BackgroundHand hygiene is known to reduce healthcare-associated infections. However, it remains suboptimal among healthcare providers. In this study, we used the Behaviour-centered Design approach to explore the facilitators and deterrents to hand hygiene among healthcare providers in the Kampala Metropolitan area, Uganda.MethodsWe conducted a formative qualitative study as part of a cluster randomised trial in 19 healthcare facilities (HCFs). The study used 19 semi-structured and 18 key informant interviews to collect data on hand hygiene status and facilitators and deterrents of hand hygiene. Research assistants transcribed verbatim and used a thematic framework aided by Nvivo 14.0. to undertake analysis. We used thick descriptions and illustrative quotes to enhance the credibility and trustworthiness of our findings.ResultsAbout 47.4% of the HCFs had sufficient hand hygiene infrastructure, and 57.9% did not report total compliance with hand hygiene during patient care. The physical facilitator for hand hygiene was the presence of constant reminders such as nudges, while the biological included the frequency of patient contact and the nature of clinical work. The only biological deterrent was the heavy workload in HCFs. The executive brain facilitators included knowledge of workplace health risks, infection prevention and control (IPC) guidelines, and a positive attitude. A negative attitude was the executive brain deterrent to hand hygiene. Recognition, rewards, and fear of infections were the only motivated brain facilitators. Behavioural setting facilitators included proximity to functional hand hygiene infrastructure, the existence of active IPC committees, good leadership, and the availability of a budget for hand hygiene supplies. Behavioural setting deterrents included the non-functionality and non-proximity to hand hygiene infrastructure and inadequate supplies.ConclusionsThe study revealed low compliance with hand hygiene during the critical moments of patient care and inadequacy of hand hygiene infrastructure. The deterrents to hand hygiene included a heavy workload, negative attitude, inadequate supplies, non-functionality, and long distance to hand washing stations. Facilitators included constant reminders, fear of infections, frequency of patient contact and nature of clinical work, positive attitude, knowledge of IPC guidelines, recognition and reward, good leadership, availability of budgets for hand hygiene supplies, availability and proximity to hand hygiene supplies and infrastructure and active IPC committees.Trial registrationISRCTN Registry with number ISRCTN98148144.

Prevalence and associated risk factors of Cryptosporidium infection in calves and hospitalized humans in Libo Kemkem, North Western Ethiopia.

Cryptosporidium infection is one of the major causes of acute gastroenteritis and diarrhoea caused by a protozoan parasite affecting vertebrates and humans. The disease is prevalent in cases of immunocompromised individuals. Despite the impact of the diseases in calf and hospitalized humans, well-documented studies are not available in the study area. The objectives of this study were to determine the prevalence of Cryptosporidium infection in calves and hospitalized humans and assess the major associated risk factors associated with Cryptosporidium infection in calves and hospitalized humans. A cross-sectional study was conducted from November 2020 to March 2021 on calf and human Cryptosporidium infection in Libo Kemkem District, North West Ethiopia. A total of 193 calves and 122 human stool samples admitted to the hospital were used for this study. Three kebeles were selected purposely, and individual calves were selected using a simple random sampling method. A number of sampled calves were allocated proportionally to the selected kebeles. Human samples were collected using a systematic random sampling method. Faecal and stool samples were examined using a modified Ziehl-Neelsen staining method. The overall prevalence of calf and human Cryptosporidium infection found in this study was 15.5% and 11.5%, respectively. Age of calf, breed, body condition, water source, faecal consistency and hygienic condition were found significantly (p<0.05) associated with Cryptosporidium infection in the calf. Similarly, the source of potable water, immunocompromisation and contact with domestic animals were found to be significantly (p<0.05) associated with Cryptosporidium infection in humans. There was a higher prevalence of Cryptosporidium infection in calves and humans in Libo Kemkem District. Therefore, the implementation of proper prevention methods of zoonotic Cryptosporidium infection between calf and human beings through significant risk factors is mandatory. Furthermore, additional studies to investigate the levels of economic importance of the disease should be conducted.

Investigating the mildew and yeast in the bakeries of Abhar City, Iran

The presence of mold and yeast in bread leads to contamination in bread. Cancer and estrogenic abnormalities in humans are among the diseases caused by fungal and mold mycotoxins in bread.Bread production waste was estimated at about 30 % in Iran country. A comprehensive and specific image study of the sanitary condition of bread and bakeries in Abhar city has not been done. The purpose of this study was to determine the contamination resulting in yeast and mildew on bread supplied in Abhar City bakeries, to examine the sanitary condition of bakeries, and to provide the food security of Iranians. As well as determining the impact of health status variables and the location of bakeries on mold and fungal contamination. This research was done in the bakeries of Abhar in the period of February 1, 2022 to July 1, 2022. Evaluation of mold and yeast load of 61 breads from 61 bakeries was done using sterile potato dextrose agar with Chloramphenicol plates. In order to check the hygiene status of the bakery environment, modified form of Article 13 with 56 items equal to 56 scores was completed. Variables such as baking soda, sodium dithionite, salt percentage, to evaluate mildew and yeast, and the sanitary condition of bakeries were analyzed. After evaluating health status, the score range was divided based on a 4-point Likert scale. All results were compared with the standard and contamination level of each restaurant. 31 of 60 samples (51.6 %) showed mold and yeast infection. 17 bakeries of the 61 bakeries surveyed (43 %) received 100 % points in the five sections (individual health of 14 items, food hygiene of 10 items, tools and equipment of 16 items, building sanitation of 16 items, and disinfection). 49 samples (80.3 %) of 61 breads evaluated by chemical standard such as amount of baking soda were favorable. Sixty samples (98.4 %) of 61 breads complied with the chemical standard of sodium dithionite. 5 samples (8.3 %) of the 61 breads had excess salt levels. 33 samples out of 61 tested (54.1 %) were infected with mold and yeast. Of these, 26 (78.7 %) belonged to serotypes producing toxin A. The bread quality in some bakeries in Abhar City is poor and infected with mold and yeast. Careful monitoring and monitoring of the health status of bakeries, along with training sessions for bakery staff, will lead to improved baking health.

Analysis of factors related to radiation-induced oral mucositis in patients with head and neck tumors undergoing radiotherapy

ObjectiveTo explore the risk factors of radiation-induced oral mucositis (RIOM) in patients with head and neck tumors undergoing radiotherapy. MethodsA retrospective collection was conducted on patients with head and neck tumors who underwent radiotherapy and chemotherapy in our hospital from April 1, 2015 to April 1, 2019. They were divided into an incidence group (n = 48) and a non-incidence group (n = 76) based on whether RIOM occurred, and relevant data was collected for comparison. ResultsThere were statistically significant differences between the two groups of patients in terms of tumor type, smoking percentage, education level percentage, tumor stage, oral mucosal inflammation stage, radiotherapy dose, mucosal protectants, and oral hygiene condition(P < 0.05); The regression analysis results showed that smoking (OR=1.274, 95 % CI: 1.095–2.007), high-dose radiotherapy (OR=1.223, 95 % CI: 1.098–2.077), and poor oral hygiene (OR=1.367, 95 % CI: 1.024–2.890) were risk factors for RIOM. ConclusionSmoking, high-dose radiotherapy, and poor oral hygiene were risk factors for RIOM in head and neck patients after radiotherapy and chemotherapy.

Exploring the Traditional Foodways for Nutritional Well-Being Amongst Vulnerable Communities: Insights from Ho Indigenous Community of Jharkhand, India

Nutritional well-being of Indigenous Peoples is shaped by foodways through their relationship with culturally vital indigenous foods. An exploratory mixed-methods study was conducted among Ho community of Jharkhand to get an insight into their traditional foodways. Study sites included ten randomly selected villages from three geographically distant blocks of West Singhbhum, including Sonua, Khuntpani and Chakradharpur. Qualitative enquiries included focus group discussions and village transect walk interviews which captured diverse information including food access from natural sources, market access, livelihood sources, social and cultural norms around foods, environmental factors, hygiene and sanitation conditions, and community health. Seasonal market surveys (monsoon and winter) in ten local markets provided information on food diversity and local prices. The findings revealed that foodways of Ho community are based on foraging, hunting, and traditional farming through use of available ecosystem resources. However, their traditional foodways are under threats due to livelihood and nutrition transitions. They have unique food traditions and cultures, yet their meals lack variety in terms of the foods consumed. Their smallholder farming systems are not profitable, pushing them towards rural-to-urban migration. Thus, it is crucial to promote traditional foodways of Hos to support bio-cultural knowledge, food justice and nutrition in this community. Keywords: foodways, Indigenous Populations, food beliefs, lifeways, smallholder farmers

The impact of hygienic living conditions on the differentiation of male body height at the beginning of the twentieth century in the USSR

BackgroundThe positive changes in hygienic living conditions are commonly believed to explain secular changes in body height and the age of maturity. However, it is difficult to estimate the separate impacts of these factors due to the lack of social and economic data and variations in the sources of information.We hypothesized that final male body height could be associated with various socioeconomic indicators, such as the development of the medical care system, the quality of nutrition, and the level of sanitary and hygienic conditions. Moreover, we hypothesized that male body height could be associated with the level of morbidity in the region during the time of conscript childhood (from 1 to 7 years old).Materials and methodsWe used two main sources of information in the analyses. The first is the data from the Statistical Reference Book published by the Central Statistical Committee in 1929. The second is the annual data from the Statistical Reference Book published in the Russian Empire. Since the conscripts were born between 1906 and 1909, we used datasets from 1910 to 1913. To analyze the data, we used a method of analyzing interacting variables called St. Nicolas House Analysis (SNHA).ResultsOur analyses revealed direct associations between the morbidity of some diseases and male body height and other anthropometric parameters.ConclusionsThere are associations between conscript final body height and the morbidity of influenza, dysentery and some venereal diseases, such as chancroid and syphilis. There were no associations between conscript final body height and the level of morbidity during childhood. However, other final parameters, such as BMI, weight, and chest circumference, could be associated with the morbidity of malaria, scabies, scurvy, and scarlet fever during childhood. The prevalence of these diseases could be strongly connected with unfavorable living conditions. The results are similar for both urban and rural areas.

Influence of unheated rooms on thermal comfort and energy efficiency of adjacent premises

AbstractThe research was conducted for three types of houses, including a panel house built before 1991, a brick house built in 2006, and a brick house built in 2022. It was established that the temperature difference, which is decisive when assessing the sanitary and hygienic condition of the premises, does not exceed the normative values for buildings built after 2006. In the building since 1991, the sanitary and hygienic indicators of the heated room deteriorate when the outside air temperature drops below −3 °C. At the same time, the fulfillment of the first condition of comfort in the room occurs at indoor air temperatures higher than the standard value, therefore, under the calculated conditions, residents feel discomfort when staying in such a room.

Are educational tools in oral health programs for pregnant women effective in improving the oral status of mothers and babies? A systematic review.

To analyze, through a systematic review, the effectiveness of educational tools (ETs) in Oral Health Programs (OHPs) for pregnant women in improving their oral status and thatof their babies. Searches were carried out in 5 electronic databases. Randomized (RCTs) and non-randomized clinical trials (CTs) were selected that included pregnant women exposed or not to ETs in OHPs, whose oral health status, in the pre- or postnatal period, or of their babies were verified. The types of ETs, outcomes, and results were extracted. Bias risk was assessed by ROBINS-I and RoB 2.0; and the certainty of the evidence (CE) by GRADE. A total of nine studies were included. Most used more than one ET (n = 8), with verbal guidance used in all (n = 9). Mothers showed a reduction in biofilm (n = 3), caries (n = 4) and periodontitis (n = 4). All studies with babies (n = 3) were successful in preventing caries. RCTs (n = 3) were classified as low risk of bias (n = 1), with concerns (n = 1) and high risk of bias (n = 1). CTs (n = 6) presented risk of bias as low (n = 2), serious (n = 1) and critical (n = 3). Studies about caries in babies showed high CE, and those who evaluated caries and periodontal parameters/biofilm in the mother had moderate and low CE, respectively. ETs as a strategy of OHPs for pregnant women can be effective in preventing caries in themselves and in their babies. However, despite the improvement of the mothers' oral hygiene and gingival condition, the CE was low considering this parameter.

Peri-urban agriculture and household food and nutrition security around Eldoret, Kenya

Rapid urbanisation in low- and middle-income countries, which has encroached on agricultural lands but has not been consistently accompanied by corresponding improvements in water and sanitation services, has raised questions about its impact on the food and nutrition security of households living in transitional, peri-urban areas. Through an analysis of survey data collected from 518 households living around the town of Eldoret, Kenya, we investigate the existing links between peri-urban households’ engagement in agriculture, their dietary behaviour, and their children’s nutrition outcomes. We find that peri-urban households engaged in agriculture, particularly in crop growing and in the sales of their agricultural produce, have more diverse and nutritious diets than agriculturally non-engaged households, all other things being equal. However, a significant improvement in children’s health outcomes is observed in these households only when coupled with improved water, sanitation, and hygiene conditions.

METHODS OF ORAL HYGIENE FOR CRITICAL PATIENTS IN INTENSIVE CARE UNIT. A REVIEW

Background: currently, the problem of the effectiveness and quality of oral hygiene is very relevant, however, for patients in the intensive care unit (ICU) this is extremely important issue. Purpose: to study, according to the literature sources, the state of oral hygiene for patients in the ICU, with the use of various antiseptics and methods. Methods: a literature search was conducted in the Scopus, Pubmed, Web of science, Elibrary, Google Scholar databases to study the issue of literature data on oral care methods for critical patients. Inclusion criteria: original peer-reviewed studies with a focus on evaluating the clinical effectiveness of oral care, published in the period 2000-2023. Results: most studies have found that oral hygiene in patients in the intensive resuscitation unit reduces the incidence of ventilator-associated pneumonia (VAP) but does not affect the duration of stay on artificial lung ventilation and mortality. The literature re-view included studies on the effectiveness of hydrogen peroxide n=2(10%), chlorhexidine n=10(50%), povidone iodine n=2(10%), phytopreparations n=4(20%). Conclusion: there is no universal and effective protocol for conducting the oral hygiene in the ICU patients, as well as recommendations on the choice of antiseptic, concentration and method of application. Further study of this issue is required.
