Jhajharia K, Parolia A, Shetty KV, Mehta LK

J Int Soc Prev Community Dent, 2015 Jan-Feb;5(1):1-12.
PMID: 25767760 DOI: 10.4103/2231-0762.151956

Endodontic disease is a biofilm-mediated infection, and primary aim in the management of endodontic disease is the elimination of bacterial biofilm from the root canal system. The most common endodontic infection is caused by the surface-associated growth of microorganisms. It is important to apply the biofilm concept to endodontic microbiology to understand the pathogenic potential of the root canal microbiota as well as to form the basis for new approaches for disinfection. It is foremost to understand how the biofilm formed by root canal bacteria resists endodontic treatment measures. Bacterial etiology has been confirmed for common oral diseases such as caries and periodontal and endodontic infections. Bacteria causing these diseases are organized in biofilm structures, which are complex microbial communities composed of a great variety of bacteria with different ecological requirements and pathogenic potential. The biofilm community not only gives bacteria effective protection against the host's defense system but also makes them more resistant to a variety of disinfecting agents used as oral hygiene products or in the treatment of infections. Successful treatment of these diseases depends on biofilm removal as well as effective killing of biofilm bacteria. So, the fundamental to maintain oral health and prevent dental caries, gingivitis, and periodontitis is to control the oral biofilms. From these aspects, the formation of biofilms carries particular clinical significance because not only host defense mechanisms but also therapeutic efforts including chemical and mechanical antimicrobial treatment measures have the most difficult task of dealing with organisms that are gathered in a biofilm. The aim of this article was to review the mechanisms of biofilms' formation, their roles in pulpal and periapical pathosis, the different types of biofilms, the factors influencing biofilm formation, the mechanisms of their antimicrobial resistance, techniques to identify biofilms.

J Pharm Bioallied Sci, 2018 12 21;10(4):216-225.
PMID: 30568379 DOI: 10.4103/JPBS.JPBS_296_16

Background and Objectives: Various devices have been used to maintain oral hygiene. These include toothbrush and toothpaste, mouthwash, dental floss, miswak, and toothpick. This study attempts to investigate the use of various oral cleaning devices and their perceived benefits among Malaysians.
Methods: A quantitative cross-sectional study conducted in two different cities of Malaysia. A convenience sampling approach was adopted. A total of 787 participants agreed to participate in the current research. A validated questionnaire translated into national language was used for data collection.
Statistical Analysis Used: Data analysis was performed using Statistical Package for Social Sciences version 20.
Results: About 302 respondents were in the age range of 18 - 25 years old (38.4%). There were marginally more females (55.7%) than males (44.3%). Although 99.9% of the participants used a toothbrush, a significant majority (n = 590, 75%) used more than a single device to maintain their oral hygiene. Only 311 respondents knew that toothpicks were inappropriate to use to remove food between teeth and gums, while a majority (n = 592, 75.2%) did not realize that some mouthwashes can stain the teeth. Less than half (42.1%) knew that improper use of miswak might harm the teeth.
Conclusions: Although their oral hygiene behaviors are relatively at a higher level, their perceived oral health benefits did not compare well.

Darlan DM, Tala ZZ, Amanta C, Warli SM, Arrasyid NK

Open Access Maced J Med Sci, 2017 Apr 15;5(2):142-146.
PMID: 28507618 DOI: 10.3889/oamjms.2017.014

BACKGROUND: Soil Transmitted Helminth infection is one of most prevalent health problems worldwide, especially in environments with poor sanitation. Based on World Health Organisation (WHO) data, more than 2 billion people, or 24% of the world's population, are infected with intestinal parasite. The highest prevalence is located in areas of poor sanitation and unsafe water supplies. In Indonesia, the prevalence of parasite infections is 15% of the entire population.
AIM: The purpose of this study was to determine the relationship between Soil Transmitted Helminth infection on levels of eosinophils among primary school children. In addition, this study also aimed to determine the prevalence of different types of worm infections and the levels of eosinophils in children infected with worms.
MATERIAL AND METHODS: This study was analytic observational using a cross-sectional method. The sampling technique was consecutive and in total 132 samples was obtained. The study involved primary school children in Amplas Medan and Hamparan Perak, Deli Serdang through May to October 2016. Univariate analysis was performed to determine STH infection prevalence and bivariate analysis was used to find the correlation between STH infection and eosinophil levels through a Chi square (χ2) test.
RESULTS: The results showed that the prevalence of Soil Transmitted Helminth was 7.6%. The most common types of STH infection were 3.8% with Trichuris trichiura and 3% with Ascaris lumbricoides. A significant correlation was found between Parasite infection and eosinophil levels (Contingency Coefficient (C) = 0.2, χ2 = 5.3, p = 0.021) and the risk of STH infection that caused eosinophilia or increased eosinophil levels in the children with a Prevalence Ratio (PR) of 1.56 (Confidence Interval (CI) 95%: 1.10-2.22).
CONCLUSION: It is recommended that schools at similar risk improve and maintain hygiene and healthy behaviour in the school environment and that parents and teachers pay greater attention to the cleanliness of their children.

Fulltext The effect of the SIMS Programme versus existing preschool oral healthcare programme on oral hygiene level of preschool children: study protocol for a cluster randomised controlled trial

Yusof ZYM, Anwar NH, Mohd Nor NA, Nor MM, Mustafa SE

Trials, 2021 Feb 22;22(1):156.
PMID: 33618735 DOI: 10.1186/s13063-021-05111-0

BACKGROUND: Despite the implementation of the preschool oral healthcare programme (POHP) for 5-6-year-old children over the past 3 decades in Malaysia, dental plaque and caries levels in this age group remain high. Among the child-level attributable factors are unhealthy self-care behaviours (poor oral hygiene and high sugary diet). In order to improve the children's oral health, an improved programme called the 'Senyuman Indah Milik Semua' Programme (SIMSP) or 'Beautiful Smile for All' programme is introduced. In this programme, a triad of dental hygienist-teacher-parent works together to improve children's oral hygiene levels compared with the existing POHP that involves dental hygienists only. The aim of this study is to compare the effect of the SIMSP versus the existing POHP on oral hygiene levels of 5-6-year-old children in the Kampar district, Perak state, Malaysia.
METHODS: This study is a pragmatic, cluster-randomised, parallel-group, matched pair, controlled trial with blinded outcome assessment. Randomisation is performed using a computer-generated table with a 1:1 allocation comparing the SIMSP and the POHP involving 28 preschools in the Kampar district, Perak, Malaysia. The intervention consists of preschool visits by a group of dental therapists, in-class oral health lessons and daily toothbrushing conducted by class teacher, child home toothbrushing supervised by parents, and infographic oral health messages to parents. The control consists of the existing POHP that involves preschool visits by a group of dental therapists only. The trial lasts for 6 months. Primary outcome variable is the mean plaque score change after 6 months. To determine the feasibility of the SIMSP, a process evaluation will be conducted using the perspectives of dental therapists, teachers, and parents on the appropriateness, effectiveness, facilitators, and barriers to the SIMSP implementation as well as an audit trail to assess the trial intervention.
DISCUSSION: Cluster randomisation may lead to a random effect and cluster selection bias. These factors will be accounted for when analysing the data and interpreting the outcomes. The effectiveness of the SIMSP will be evaluated by comparing the results with those of the POHP.

Graham JE, McGilligan VE, Berrar D, Leccisotti A, Moore JE, Bron AJ, et al.

Ophthalmic Res, 2010;43(1):11-7.
PMID: 19829007 DOI: 10.1159/000246573

AIM: The purpose of this study was to survey the attitudes of optometrists and ophthalmologists, located in a number of different countries, towards diagnostic tests and therapies for dry eye disease.
METHODS: A web-based questionnaire was used to survey attitudes using forced-choice questions and Likert scales.
RESULTS: Sixty-one respondents (23 ophthalmologists and 38 optometrists) reported a wide range of patient dry eye symptoms. A large variation in use of diagnostic tests was noted. Patient symptoms and fluorescein staining were reported to be significantly more valuable and more frequently performed than any other test. Artificial tear supplements and improved lid hygiene were the preferred therapeutic options selected by the entire group. The results demonstrated a wide variation in attitudes in relation to satisfaction with the range of available diagnostic and therapeutic options.
CONCLUSIONS: This study indicates that the interest for the issue of dry eye is relatively limited amongst eye professionals, as demonstrated by the poor participation in the questionnaire.

Introduction: Poor hygiene practice is an important factor that lead to morbidity and mortality among young chil- dren which are common among the indigenous population due to the lack of access to health services and their unique beliefs and practices. This study aimed to identify the socio-demographic determinants of hygiene practices among the indigenous (known as Orang Asli in Malaysia) primary caregivers of children under the age of three in Malaysia. Methods: A cross-sectional study was conducted among 166 primary caregivers of Orang Asli children of below three years old in Kuala Langat District. Data was collected using a validated and pre-tested questionnaire via face-to-face interviews with individual respondents. The questionnaire consisted of two main sections: sociodemo- graphics and hygiene practice. Results: A majority of the Orang Asli primary caregivers had good hygiene practices (78.9%). The number of children under five years old living at home was significantly associated with hygiene prac- tice and it was the only significant determinant or predictor of good hygiene practice among the Orang Asli primary caregivers. Conclusion: The number of children under five years old living at home is an important factor to ensure good hygiene practices among the primary caregivers of Orang Asli children. This factor need to be taken into con- sideration in monitoring children health status by the health staff by emphasizing the importance of hygiene practice in the prevention of infectious diseases and malnutrition among Orang Asli children.

MyJurnal

The aim of this study was to evaluate the levels of C-reactive protein (CRP) and
interleukin-6 (IL-6) in the gingival crevicular fluid (GCF) among stroke survivors in relation to
the oral hygiene status and stroke characteristics. Methods: A multi-centre cross-sectional
study was conducted among hospitalised stroke survivors. Socio-demographic data were
collected. Oral clinical assessment (dental plaque scores) and functional dependency levels
scores were carried out. Gingival Crevicular Fluids were collected, using absorbent papers
and analysed using ELISA kit. Descriptive statistic and correlation analyses were performed
using proportion and Spearmen correlation coefficient test. Results: A total of 53 patients were
recruited from five public hospitals. There was a significant correlation between CRP and IL-6
levels of GCF (P=0.021, r=0.21). A significant correlation was also observed between CRP
levels in GCF with dental plaque scores and functional dependency levels. There was no
statistically significant correlation found between IL-6 levels in GCF with dental plaque scores
and functional dependency levels. Dental plaque scores were associated with high levels of
CRP in GCF (P=0.014), and swallowing problem was associated with high levels of IL-6 in
GCF (P=0.002). Conclusions: IL-6 levels in GCF were correlated with the levels of CRP in
GCF. High CRP and IL-6 levels in GCF were significantly associated with dental plaque scores
and swallowing condition (presence of dysphagia), respectively. Thus, this pilot study suggests
that CRP level in the oral cavity respond to the oral health conditions and may not be a
predictor factor of stroke outcomes. Further studies are warranted to compare the level of
inflammatory biomarkers from the oral cavity and serum in relation to the stroke conditions and
outcomes.

Background. Pre-school children are at a higher risk to acquire infectious diseases such as hand, foot and mouth disease due to their immature immune system. Good hand hygiene prevents transmission of infectious diseases. This study aimed to determine the knowledge and practices of hand hygiene among pre-schoolers. Methods. In this prospective, multi-center study, the pre-schools were selected according to the selection criteria. A questionnaire consisting of socio-demographics, knowledge and practices of hand hygiene were administered via face-to-face interview during the pre- and post-intervention period. A total of 435 pre-schoolers aged 5 and 6 years old from 2 pre-schools within Klang Valley, School P (test group) and School C (control group) were involved in this study. The test group was provided with comprehensive hand hygiene education including video on proper handwashing technique during the 2 months intervention period, whereas the control group did not receive any form of intervention. The data were statistically analyzed using descriptive analysis and independent t-test. Results. Majority of pre-schoolers gained knowledge of handwashing from their parents. However, only 63% demonstrated good handwashing technique. Test group were significantly better (P

PMID: 32640588 DOI: 10.3390/antibiotics9070382

Methicillin-resistant Staphylococcus aureus or MRSA infection is virulent and presents with a broad spectrum of severity. Limited regional reports that specifically outlined the potential risk of medical students being part of the dissemination of MRSA in healthcare settings were noted. This study aims to assess the prevalence and contributory factors of colonization of MRSA on neckties, headscarves, and ID badges among medical students in a local medical university in Malaysia. A cross-sectional study was conducted involving 256 medical students. A validated questionnaire was used to collect the data, and sample swabs were collected between July and August 2013 by swabbing neckties, headscarves, or identification badges. The swabs were then streaked onto mannitol salt agar (MSA) and incubated at 37 °C overnight. Out of 433 samples taken, 40 swabs (9.24%) were positive for Staphylococcus aureus. Out of the 40 swabs, five (12.5%) isolates were MRSA (one culture was isolated from the headscarf of a preclinical student, one culture was isolated from the necktie of clinical students, while the remaining three were isolated from identification badges of clinical students. There was no significant association between age, gender, ethnicity, and phase of medical students with the colonization of MRSA (p > 0.05). There was a significant association between knowledge score on hand hygiene practice and phase of medical students. MRSA colonies were present on neckties, headscarves, and identification badges of medical students of all phases. The findings from this study suggest the need for improvement of hand hygiene knowledge and discontinuity of mandatory use of physical ID badges and neckties among medical students.

Introduction: World Health Organization in 2019 reported that about 1.5 billion people are infected with soil-trans-mitted helminths (STH) worldwide. Infected children with STH might manifest signs of anaemia and impaired nutri-tionally or physically. This study aimed to look at the prevalence of STH in the area of North Sabah among rural pri-mary schools and examine the associated factors. Methods: A cross-sectional study was conducted in four selected primary school in the district of Kudat of Sabah from 2014 to 2015. Tools used for the study were questionnaire and stool sampling. Questionnaire focused data on sociodemographic, hygiene and use of anti-helminths drugs. Stool samples collected were sent for microscopic examination for presence of STH ova. Written consents were obtained from parents/guardians. Chi-square was used to examine the association of having STH and factors on utilities fa-cilities, hygiene and anti-helminths drug. SPSS version 23 was used for statistical analysis. Results: There was 433 school children aged 7 to 12 years old with 224 males and 209 females respondents. Three-quarters main source of water supply in the homes from treated water. Those with proper built toilet were 96%. Practices of washing hands after toilet and before eating were 96% as well. Almost 95% wear slippers when outside homes. Only 61% took their anti-helminths drug in the past 1 year while in the last 6 months the uptake was 38.7%. The prevalence of positive ova of STH in the stool sample was 57 out of 433 or 13.2%. STH infection was not statistically significant associated with the above factors. Conclusion: The prevalence of STH infection among primary school children in the district of Kudat although has lowered over the years is still considered higher than most states in Malaysia. Continuous public health intervention is necessary to further bring down the prevalence of STH infections.

Introduction: Ventilator-associated pneumonia (VAP) is defined as pneumonia that occurs 48-72 hours or there-after following endotracheal intubation. VAP increased health care costs due to hospital length of stay. Since VAP can be prevented, this study underscores the importance of identifying the current knowledge and practice on the prevention of VAP among the ICU nurses in Queen Elizabeth Hospital 2 (QEH2). The objective of this study is to determine the nurse’s knowledge and practice towards VAP prevention. Methods: The methodology used for this study is a cross-sectional study to evaluate nurses’ knowledge and practice in the ICU, QEH2. 82 ICU QEH2 nurs-es participated. Data were collected using a modified structured questionnaire based on the checklist of VAP data elements. The elements covered in the questionnaire consist of three parts, which are Part A on socio-demographic information, Part B on knowledge ventilator-associated pneumonia events and Part C on nurse’s prevention practice on ventilator-associated events. The data was analyzed using SPSS version 20. Results: The overall results of this study are 45.1% of the nurses were less knowledgeable on VAP prevention and this could lead to a prevalence of VAP in the unit. VAP is a new concept implemented in 2013, meaning that 48.53% (n=33) nurses who trained 2-5 years ago may have not covered VAP in their infection prevention and control training. Most of the ICU nurses did not profoundly practices on subglottic suction (35/82), hand hygiene prior suctioning (40/82), hand hygiene after ETT suction (16/82) and delirium risk assessment (1/82). As a discussion, this could mean the ICU nurses do not have adequate knowledge and practice awareness on VAP prevention. Conclusion: For the conclusion of this study, the nurses working in ICU, QEH2 practiced most of the recommended VAP prevention but not all. Continuous training on prevention for VAP in ICU needs to be review. The hospital management to ensure the availability of the facilities needed and the adoption of guidelines based on evidence-based practice.

Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) is a bacteria or germ which many people carry in their nose or on their skin and it is resistant to a range of antibiotics including methicillin. The primary mode of transmission of S. aureus is by direct contact usually, skin-to-skin contact, although contact with contaminated objects and surfaces or might also play a role. The risk of infection by antibiotic-resistant organisms is a common problem in a hospital setting. When it comes to caring for the patient with an infectious disease such as MRSA, most nursing students tried to avoid caring for the patient because they fear of getting infected. So, in this regards that it is important to find out the perception of nursing students towards MRSA patients. Methods: This study is a descriptive cross-sectional study design and a structured questionnaire used to evaluate the perception among student nurses regarding care for a patient with MRSA. The population of this study consists only of the nursing student of year 2 and year 3, which is 118 students. A minimum of 60 respondents selected by convenient sampling from this population. Results: Findings showed the respondent’s perception towards MRSA patients that 83.55% (n=55) of the respondent has the feeling of avoiding getting close to MRSA patients. While 16.7% (n=11) did not have the feeling to avoid them. 47% (n=31%) respondents felt refused to do any procedure on MRSA patients. While 53% (n=35) did not feel refuse to do any procedure on MRSA patient. 92.4% (n=61) respondents wear full PPE before caring for patients with MRSA. The other 7.6% (n=5) did not wear full PPE before caring for patients with MRSA. 98.5% (n=65) respondents always follow 5 moments of hand hygiene. While the other 1.5% (n=1) did not always follow 5 moments of hand hygiene. Conclusion: To conclude, even though most of the respondents know about MRSA but some of them did not know that MRSA is curable or not, some confusion about the mode of transmission of MRSA and did not know that they should wear full PPE in caring for the patient with MRSA. Lack of knowledge about MRSA might influence them to ask their friends to do procedures for the patient instead of doing it by themselves. Without good knowledge and skills about how to handle infectious patients, it is difficult for the nursing students to approach the patient with an infectious disease such as MRSA.

MyJurnal

Clean, safe and readily available water is very crucial in everyday life, especially for health, hygiene, and the productivity of the community. Unfortunately, increase in contaminants in water supplies from human activities and industrialization is very worrying. Conventional wastewater treatment includes the usage of alum that will affect health with prolonged consumption. This research was carried out to focus on the development of wastewater treatment system using adsorbent from Moringa oleifera seeds. Adsorbent was successfully synthesized from the seeds of Moringa oleifera. Characterization of the sample was made using X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscope (SEM), while the effectiveness of water treatment was analyzed using Turbidity Meter. Then, all samples were tested against kaolin wastewater. XRD results showed that all the adsorbent samples were amorphous in nature. FTIR results indicated that there were hydroxyl group and carboxylic group in the sample representing numerous oxygen-riddled functional groups on the surface. From SEM results, it was clearly shown that the pore structure and size of Moringa oleifera affected the capability of adsorption where the smaller the size, the more effective the sample. Turbidity test showed that the sample that worked best for wastewater treatment was adsorbent from Moringa oleifera seeds in size of 125µm that was heated for 4 hours with 93.76% turbidity removal. Therefore, this study proved that the adsorbent from Moringa oleifera seeds is very suitable for high turbidity wastewater treatment. Further studies investigating the combination of conventional activated carbon with adsorbent from Moringa oleifera seeds should be conducted before these samples are made available for further use so that we can compare which sample works best for wastewater treatment.

Introduction: Childhood stunting is recognised as one of the most significant
barriers to human development. This cross-sectional study aimed to determine the
factors associated with stunting among Orang Asli (OA) preschool children in Negeri
Sembilan, Malaysia.

Methods: A total of 264 children (50.9% boys and 49.1%
girls) aged 2-6 years (M=4.04, SD=1.21 years) including their mothers from 14 OA
villages in Negeri Sembilan participated in this study. Mothers were interviewed to
obtain information regarding socioeconomic status, sanitation facility and personal
hygiene. The height of the children and their mothers were measured. Venous
blood samples were drawn from the children to estimate haemoglobin level, and
stool samples were collected to screen for intestinal parasitic infections.

Results:
Approximately one third of the children (35.6%) and 7.8% of the mothers were
stunted. One in five of the children were anaemic (21.6%), while one- third had
intestinal parasitic infections (35.0%). Low birth weight (AOR=2.526, 95% CI: 1.310-
4.872; p=0.006), anaemia (AOR=2.742, 95% CI: 1.265-5.945; p=0.011), presence
of intestinal parasitic infections (AOR=2.235, 95% CI: 1.310-3.813, p=0.003), not
wearing shoes (AOR=2.602, 95% CI: 1.453-4.660; p=0.001), absence of piped water
at home (AOR=2.395, 95% CI: 1.047-5.476; p=0.039), dirty nails (AOR=1.956, 95%
CI: 1.163-3.289, p=0.011), and stunted mothers (AOR=3.443, 95% CI: 1.334-8.890;
p=0.011) were identified as significant factors for childhood stunting.

Conclusion:
It is suggested that the factors identified associated with childhood stunting be
included in future intervention programmes that address stunting among OA
children.

Intestinal parasitic infections (IPIs) are among the most important infectious diseases in Iran. A cross sectional study was designed to determine frequency of intestinal parasites among referrals to a large teaching hospital in Khuzestan, Southwest of Iran, 2017. A total number of 5613 stool samples were examined through direct smear and formalin-ether concentration methods to detect possible parasitic infections. Samples consisted of 2643 (47.09%) male and 2970 (52.91%) female. A total of 1468 (26.15%) samples were positive (13.11% male and 13.4% female) and 4145 (73.85%) were negative. The results also showed that 255 of samples had more than one type of parasite (mix infections). Counting single and mix parasite infections, the total number of positive cases reached to 1723. Helminthes parasites were present in 12 (0.7%) cases, while intestinal protozoan parasites were in 1711 (99.3%) cases. Almost equally, pathogenic and nonpathogenic parasites infected 860 (49.91%) and 863 (50.09%) of patients, respectively. The frequency for helminthes was determined at 0.52% with Hymenolepis nana and Enterobius vermicularis however, Giardia lamblia in 38.54% and Entamoeba histolytica/dispar at 10.68% were concluded as protozoa elements. The IPIs frequency was recorded in female and male patients at 49.16% and 50.14%, respectively. According to the current results the infection rate of intestinal parasites has been significantly reduced especially for helminths infections in this region possibly due to public attention to health issues such as; increased awareness of people, improvement of sanitation, seasonal variations, health education and personal hygiene.

Intestinal parasitic infections are among important health problems in developing countries. In societies living in low socioeconomic conditions, it has been neglected and mostly affects children. It is important to determine the prevalence and type of intestinal parasites in order to determine the intervention strategies for these infections. Therefore, the aim of this study is to evaluate intestinal parasite prevalence and IgE levels and the factors associated with the region in which the children population live, in Sirnak province, in the eastern of Turkey. A total of 357 symptomatic children aged 4 to 12 years, who were admitted to the Paediatric Polyclinic of Sirnak State Hospital, were examined prospectively. The collected stool samples were examined with direct wet-mount and concentration method under light microscope. In addition, total serum IgE levels were compared among 223 children with parasitic disease and 134 children without parasitic disease. One or more intestinal parasites were detected in 223 out of the 357 children participating in the study. The ratio of single, double, and triple parasitic infections in children was 32.5 %, 22.4 % and 7.6 %, respectively. The most common parasites determined in the study were Taenia spp. (39.9%), Enterobius vermicularis (38.6%) and Giardia intestinalis. (30 %). The difference between IgE levels determined in both groups was not regarded to be statistically significant. This study indicated that that intestinal polyparism is very common in children living in the province of Sirnak, which is located in the east of Turkey, neighbouring Iraq and Syria in the South. For this reason, sustainable control measures are urgently needed to improve personal hygiene and sanitation, to provide a healthy infrastructure and to improve the quality of existing water resources.

Helminth infections (HIs) are an important public health problem in tropical countries, and the associated problems have been neglected in rural areas of Thailand. Therefore, this study reports the prevalence and intensity of HIs among inhabitants of the Khon Sawan district, Chaiyaphum province, and Kaeng Samnam Nang district, Nakhon Ratchasima province, which are located near the Chi River and Lahanna water reservoir, northeastern Thailand. A cross-sectional descriptive study was conducted between July 31, 2018, and June 30, 2019, among rural villagers from 40 rural villages in 4 subdistricts. The participants were selected from the village enrolment list after proportional allocation of the total sample size. Faecal samples from 691 inhabitants were prepared using solvent-free faecal parasite concentrator, and helminths were then detected using a light microscope. Statistical analysis included the Chi-square test with Yates correction, and multivariable logistic regression was performed. A P-value of <0.05 was considered statistically significant. The prevalence of HIs was 2.03%. The most prevalent helminths were Opisthorchis viverrini (1.31%), followed by Strongyloides stercoralis (0.44%), Ascaris lumbricoides (0.29%), hookworm (0.15%), Teania spp. (0.15%) and one minute intestinal fluke (0.15%). Coinfections were identified in 2 cases for S. stercoralis and hookworm and 1 case for O. viverrini and S. stercoralis infection. All infected participants had a light intensity of HI. There was no significant difference between general characteristics for all HIs. The prevalence of HIs was not significantly associated with general characteristics. This study indicates that the infections result mainly from foodborne helminths and skin-penetrating nematodes. Therefore, interventions should concentrate on the personal hygiene of the population and improving sanitation to reduce HIs in this area.

Blastocystis is one of the most common parasites inhabiting the intestinal tract of human and animals. Currently, human Blastocystis isolates are classified into nine subtypes (STs) based on the phylogeny of their small subunit ribosomal RNA (SSU rRNA) gene. Although its pathogenicity remains controversial, the possibility of zoonotic transmission was recognized since eight of the nine STs (except for ST9) have been reported in both humans and animals. A cross-sectional study was conducted to determine the prevalence and subtype distribution of Blastocystis isolated from humans and associated animals in an indigenous community with poor hygiene in Malaysia, where the risk of parasitic infection is high. A total of 275 stool samples were collected, subjected to DNA extraction and amplified by PCR assay. The Blastocystis-positive amplicons were then purified and sequenced. Phylogenetic tree of positive isolates, reference strains and outgroup were constructed using maximum likelihood method based on Hasegawa-KishinoYano+G+I model. The prevalence of Blastocystis infection among humans and domestic animals by PCR assay were 18.5% (45/243) and 6.3% (2/32), respectively. Through molecular phylogeny, 47 isolates were separated into five clusters containing isolates from both hosts. Among human isolates, ST3 (53.3%) was the predominant subtype, followed by ST1 (31.1%) and ST2 (15.6%). Chicken and cattle had lower proportions of ST6 (50%) and ST10 (50%), that were barely seen in humans. The distinct distributions of the most important STs among the host animals as well as humans examined demonstrate that there is various host-specific subtypes in the lifecycle of Blastocystis.

Hand hygiene is the topmost crucial procedure to prevent hospital-acquired infections. Choosing an effective hand disinfectant is necessary in enforcing good hand hygiene practice especially in hospital settings. The aim of the study was to investigate the efficacy of Aaride AGT-1 as a hand disinfectant for the inhibition of pathogenic microorganisms' transmission among both patients and personnel in the health care system compared to other commercially available disinfectants. In the present study, a new hand disinfectant Aaride AGT-1 was tested against several bacterial and viral pathogens to evaluate its antimicrobial activity profile. The results revealed that Aaride AGT-1 displayed the highest antibacterial activity against five pathogenic bacteria including MRSA when compared to other commercially available hand sanitizers. Aaride AGT-1 showed the lowest percentage needed to inhibit the growth of bacterial pathogens. In addition, results obtained from time killing assay revealed that Aaride AGT-1 demonstrated the best killing kinetics, by eradicating the bacterial cells rapidly within 0.5 min with 6 log reduction (>99.99% killing). Also, Aaride AGT1 was able to reduce 100% plaque formed by three viruses namely HSV-1, HSV-2 and EV-71. In conclusion, Aaride AGT-1 is capable of killing wide-spectrum of pathogens including bacteria and viruses compared to other common disinfectants used in hospital settings. Aaride AGT-1's ability to kill both bacteria and viruses contributes as valuable addition to the hand disinfection portfolio.
