Edukasi Tentang Personal Hygine Sekolah Dasar Di Wilayah Kerja Kecamatan Tabunganen

In the nursing field, personal hygiene is considered one of the basic human needs. Personal hygiene refers to individual cleanliness and health practices aimed at preventing the spread of diseases to oneself and others. Hygiene is important because maintaining good personal hygiene minimizes the entry points (portals of entry) for microorganisms that are present everywhere, ultimately preventing individuals from falling. Poor personal hygiene, on the other hand, increases the likelihood of contracting various diseases, such as scabies, infectious diseases, oral and dental diseases, and gastrointestinal illnesses. It can even impact the function of specific body parts, such as the skin. The method used was a demonstration of the six steps of proper handwashing to elementary school students in the Tabunganen sub-district. The results showed that the majority of students were able to wash their hands correctly after the demonstration. It can be concluded that all students were enthusiastic about learning the proper handwashing technique and were able to apply it correctly and effectively. In conclusion, personal hygiene is crucial in preventing the spread of diseases, and maintaining good personal hygiene practices is essential. The study demonstrated the effectiveness of a handwashing demonstration in teaching elementary school students in the Tabunganen sub-district the proper and correct handwashing technique. The findings highlight the students' enthusiasm to learn and their ability to apply the knowledge effectively.

Prevalence of scabies and associated factors among Governmental Elementary School Students in Gondar town Northwest Ethiopia

Scabies is an infestation of the skin by the human itch female mite. Scabies infestation provides an important portal of entry for bacteria and complement inhibitors from scabies mites.

Teleost Eye Is the Portal of IHNV Entry and Contributes to a Robust Mucosal Immune Response.

The ocular mucosa (OM) is an important and unique part of the vertebrate mucosal immune system. The OM plays an important role in maintaining visual function and defending against foreign antigens or microorganisms, while maintaining a balance between the two through complex regulatory mechanisms. However, the function of ocular mucosal defense against foreign pathogens and mucosal immune response in bony fish are still less studied. To acquire deeper understanding into the mucosal immunity of the OM in teleost fish, we established a study of the immune response of rainbow trout (Oncorhynchus mykiss) infected with the infectious hematopoietic necrosis virus (IHNV). Our findings revealed that IHNV could successfully infiltrate the trout's OM, indicating that the OM could be an important portal for the IHNV. Furthermore, qPCR and RNA-Seq analysis results showed that a large number of immune-related genes were significantly upregulated in the OM of trout with IHNV infection. Critically, the results of our RNA-Seq analysis demonstrated that viral infection triggered a robust immune response, as evidenced by the substantial induction of antiviral, innate, and adaptive immune-related genes in the OM of infected fish, which underscored the essential role of the OM in viral infection. Overall, our findings revealed a previously unknown function of teleost OM in antiviral defense, and provided a theoretical basis for the study of the mucosal immunity of fish.

Neurohumoral gate for the entry of coronavirus into the central nervous system through the cribriform plate of the skull

Recent research has shown that there are different drainage systems in the brain. During the drainage of cerebrospinal and interstitial fluids, intracerebral (intracranial) lymph is formed, which becomes part of the glymphatic system. Later, the glymphatic system was subdivided into periand paravascular spaces, but their existence has not yet been proven. The article contains data on the anatomy of the lamina cribrosa, its age-related changes, the characteristics of the lymphatic system and the theory of the existence of glymphatic vessels in this area. We also hypothesize that in addition to the classical view, which assumes that viruses enter the central nervous system (CNS) through the blood-brain barrier or with the help of immune cells, there are other routes of pathogen entry, for example through the glymphatic system. Possible routes of movement of cerebrospinal and interstitial fluids through the structures of the nervous system and other systems are considered. The lamina cribrosa is considered a possible portal of entry for viruses into the CNS, in particular for the SARS-CoV-2 virus. In our review, we analyzed the likely mechanisms of SARS-CoV-2 spread in the central nervous system and the possible consequences of previous viral disease.

Population genetics of Aedes albopictus in the port cities of Hainan Island and Leizhou Peninsula, China

BackgroundAedes albopictus is an important vector of arboviral diseases, transmitting yellow fever, dengue fever, chikungunya and Zika. Monitoring its population genetic diversity and genetic differentiation has become essential for the control of infectious disease epidemics, especially in the functional areas of ports of entry. Population genetic monitoring of Ae. albopictus in the port area can help in the monitoring of port mosquito invasions and establishing port sanitary and quarantine measures to prevent the introduction and transmission of vector-borne diseases. MethodsSeventeen populations of Ae. albopictus were collected from five port cities on Hainan Island and the Leizhou Peninsula, 8 populations were collected from port areas, 4 from urban areas and 5 from rural areas. Nine microsatellite loci and the mitochondrial COI gene were used to study the population genetic diversity, population genetic structure and interpopulation gene flow of Ae. albopictus. ResultsThe nine microsatellite loci used were highly polymorphic, with an average PIC value of 0.768. The UPGMA genetic tree, STRUCTURE barplot and PCoA analyses showed that the 17 Ae. albopictus populations could be divided into three genetic groups. All 17 populations showed high haplotype diversity (Hd = 0.8069–0.9678) and formed 133 distinct haplotypes. These haplotypes can be divided into four genetic clades, but they are not associated with the geographical distribution of Ae. albopictus. Fst and Nm showed strong gene flow and little differentiation among populations. ConclusionAe. albopictus in port areas are not significantly different from urban and rural populations due to strong gene flow, which prevents differentiation and increases the genetic diversity of the populations. High genetic diversity facilitates mosquito adaptation to complex environmental changes, which is a challenge for vector-borne disease control in port areas.

A longitudinal analysis of arrival infrastructures: The geographic pathways of EU labour migrants in the Netherlands

AbstractAlthough traditional migration research focuses predominantly on large cities as ports of entry for migrants, increasingly more migrants start in smaller cities and rural areas. These mobility patterns give access to specific arrival infrastructures with differentiated and often unequal opportunities. Current research has addressed the multiplicity and political nature of arrival infrastructures, but what happens after arrival remains a black box. By building on micro register data, this study employs a longitudinal approach to trace the trajectories of EU labour migrants in the Netherlands across time and space. Our findings indicate that among those who choose to remain in the Netherlands, internal migration is largely characterized by geographical immobility. When people did move to a different type of residential location, it was often to more urbanized places. As mostly migrants with a higher income made these moves, this strengthened the dualization of more precarious migrants in rural areas and more well‐off migrants in larger cities.

Demographic Profile and Outcome of Pediatric Intensive Care Unit.

Pediatric intensive care provides better observation as well as an intensive treatment, which helps to cure, support, and provide better outcomes for sick children. This study aimed to describe the demographic profile and the outcome of PICU patients, and evaluate the relationship of diagnostic categories with treatment and outcome. This retrospective cross-sectional study was conducted in a six-bedded PICU from 1 March 2021 to 1 March 2022. Bivariate analysis was used to identify the association between dependent and independent variables. The infants admitted below 6 months of age were 63 (22.3%) and had male predominance accounting for 64%. The main portal of entry of the admitted cases was emergency ward 214(75.6%). Most of the patients 153(54.1%) were admitted for intensive monitoring of their abnormal vitals along with critical care according to our PICU protocol. Respiratory illness 122(43.1%), neurosurgical illness 59(20.8%), and primary infectious disease 52(18.3%) were the common reason for PICU admission. Post-major surgery 2(66.7%), hematological illness 3(37.5%), and cardiac disorders 1(20%) had high mortality rates. Among the portal of admission, the majority of the children (80.0 %) who were admitted to the PICU through the emergency ward died before exiting from the PICU (p<0.0001). Respiratory illness was the most common cause of admission and post-major surgery had the highest mortality rate. Portal of entry was statistically associated with patient characteristics and had a significant relationship with the outcome. Similar studies in other health institutions are required to further analyze the demographic profile and outcome of pediatric critical care in Nepal.

Management of Head and Neck Cellulitis in a Patient Immunocompetent

Head and neck cellulitis are severe infections, sometimes necrotizing, whose diagnosis is difficult at an early stage. We report the clinical observation of a 60-year-old patient who presented to the emergency room for a right laterocervical swelling associated with a deterioration in general condition. The head and neck CT scan revealed abscessed right cervical cellulitis. The patient underwent drainage and debridement in the operating room with wide necrosectomy and placement of a Delbet blade, associated with dual antibiotic therapy. The evolution was marked by an improvement in the patient's clinical condition. The aim of this work was to highlight the importance of emergency medical-surgical care, without forgetting the treatment of the portal of entry. The progression in the absence of treatment is towards sometimes fatal complications. The prognosis of these infections depends on the precocity of the treatment, its initial quality and the terrain.

Demographic and travel characteristics and self-reported predeparture SARS-CoV-2 testing behavior in air passengers entering the United States from foreign destinations from July to September 2021.

From January 2021 to June 2022, the United States Centers for Disease Control and Prevention required predeparture SARS-CoV-2 testing for all air passengers arriving into the United States from a foreign country. Using data collected during a surveillance project, we described predeparture testing behavior among a convenience sample of international air passengers entering the United States from July to September 2021 at six US ports of entry. We analyzed pairwise relationships between self-reported test type, test timing, demographic and travel characteristics, and COVID-19 vaccination status using chi-square and Fisher's exact tests. Participants were more likely to get a NAAT versus antigen test if they identified as non-Hispanic Asian or Pacific Islander (68.2%, n = 173), non-Hispanic Black (62.6%, n = 147), or if they preferred not to report race and ethnicity (60.8%, n = 209) when compared to those who identified as non-Hispanic White (47.1%, n = 1086, all p < 0.05). Those who identified as Hispanic or Latino (n = 671) were less likely to get a NAAT than the non-Hispanic White group (39.5% vs. 47.1%, p < 0.05). Participants arriving in the US from the Americas were less likely to get a NAAT (38.5%, n = 871) compared to those arriving from Europe (45.5%, n = 1165, p < 0.05). Participants who reported receiving their predeparture test 2 days or 3 or more days before departure were more likely to report receiving a NAAT (52.2%, n = 879, and 60.2%, n = 410, respectively) than those who reported testing within 1 day (41.4%, n = 1040, all p < 0.001) of departure. Test type was significantly associated with race and ethnicity, departure region, and test timing. Differences likely reflected regional disparities in the availability of tests at the time of the activity. Discrepancies in predeparture test timing and type worldwide may have consequences for the effectiveness and equity of travel requirements in future pandemics.

Prevalence and Characterization of External Cervical Resorption Using Cone Beam Computed Tomography

IntroductionThe aim of this study was to assess the prevalence of external cervical resorption (ECR) and characterize the cases of ECR using cone beam computed tomography (CBCT). MethodsHigh-resolution CBCT scans of 6216 patients (2280 males and 3936 females), consecutively acquired during the period July 2021 to March 2022, were analyzed. Identified cases of ECR were characterized by 3 evaluators regarding lesion height, circumferential spread, portal of entry proximity to root canal, stage, location, and width. ResultsIn a total of 38 patients and 40 teeth, ECR cases demonstrated an incidence of 0.61%. The median age of the patients was 39 years. Prevalence of ERC was 0.78% among males and 0.50% among females. The most affected teeth were the maxillary incisors and canines. The most frequent characteristics of the lesion were: extension up to the cervical third (47.5%), more than 270° circumferential spread (42.55%), probable pulpal involvement (57.5%), progressive stage (65%), supracrestal (52.1%) and mesial (34.7%) localization of >1 mm in size (52.1%) portals of entry. Cases with greater longitudinal involvement also showed greater circumferential progression (P = .008). There was no association between portal of entry location and bone crest or ECR reparative phase (P = .42). Inter-rater agreement ranged from good to very good. No association between portal of entry and ECR progression was observed. ConclusionsECR showed low prevalence in the Brazilian population, affecting mostly anterior maxillary teeth of patients within a wide age range. CBCT allowed characterization of ECR lesions with good interobserver agreement.

Do we need to improve the general oral health of our population to reduce the risk of Infective Endocarditis?

Abstract Background Emphasis is placed on the link between oral health and Infective Endocarditis (IE), particularly around odontogenic infections and specific dental procedures. The Adult Dental Health Survey in 2009 showed 45% of adults in the UK required dental intervention typically associated with developing IE. Antibiotic prophylaxis in this context is not without controversy. With gum and periodontic disease endemic, is the modern issue one of generalised poor oral health as a risk factor for IE? Purpose To determine the impact of oral health on risk and outcome in IE. Terminology SDCEP published dental guidelines of when to consider AP against IE for dental procedures. It identifies dental procedures that can cause transient bacteraemia. Methodology Data were collected from October 2020-Januaury 2023 in 123 patients with confirmed IE at a central London cardiac surgical centre. Patients had a focussed dental assessment with history, intraoral examination and dental panoramic radiograph to determine the risk and extent of oral disease. Results Average age was 54.2years. 77/123 (63%) had native IE (NVE) and 46 (37%) prosthetic (PVE). 17 (37%) cultured oral organisms from blood (Table 1); 8 (47%) of these organisms are associated with active dental disease (decay, periodontal disease, dental infection). Organisms can be found in Table 2. However, 93/123 (76%) had oral caries requiring dental treatment, irrespective of typical portal of entry for that organism. The proposed dental treatment posed a high risk for causing IE in 70%. 93/123 (76%) needed further dental treatment within six months rendering only 12% of patients orally stable. Oral organisms were seen more frequently in NVE (41/77) vs PVE (17/46). There was no difference in the incidence of dental disease requiring treatment (77% NVE vs 74% PVE). Whilst 27% of PVE had had recent (within 4 months) dental treatment compared to 73% NVE, only 1 PVE patient grew an oral commensal compared to 82% of NVE patients. Conclusion Prevention of IE is key to reducing the morbidity and mortality of this disease. We see oral commensals causing IE in 47%, with only 12% of this modern IE cohort dentally stable. Despite this, there was no difference in rates of dental disease requiring invasive treatment when stratified by oral vs non-oral organisms. A robust public health strategy is required to reduce the risk of oral disease driving IE.

Tetanus patient profiles and factors affecting clinical outcomes at Dr. Soedono general hospital, Madiun in 2019-2020

Link of Video Abstract: https://youtu.be/VC3Gcd7oS5Y Introduction: Tetanus is a disease that can be diagnosed clinically. However, there is a lack of research data on tetanus patients and their clinical outcomes, especially in adult tetanus patients in Indonesia. This study aims to determine the factors that influence the outcome of tetanus patients. Method: A cross-sectional study was performed from May to June 2021 at Dr. Soedono Madiun General Hospital. Subjects were recruited by total sampling. The data that will be taken in this study are gender, age, immunization history, incubation period, onset, port of entry, Philips score, and clinical outcomes of patients. Result: Were 112 patients diagnosed with tetanus at Dr. Soedono General Hospital from January 2019 to December 2020. The male subjects outnumbered female subjects by 81.3%. The youngest subject was 19 years old, and the oldest was 81 years old. The tetanus immunization status showed that 2 patients were known to be fully immunized, 21 were not fully immunized, and 89 (79.5%) had unknown immunization status. This study showed that the port of entry of the wound is most often the entry point for tetanus in the inferior extremity of 72 patients (64.3%). Most onset occurred in 1-7 days, with a mean onset for generalized tetanus was 2.3 ± 1.8 days. The mean incubation period for the appearance of tetanus symptoms in this study was 9.4 ± 5.6 days. The most common comorbid disease in this study was diabetes mellitus (11.6%). This study's clinical outcome of tetanus showed that 74 patients (66.1%) had improved, while 38 patients (33.9%) died during treatment. Discussion: This study's most common port of entry was on the inferior extremities. This lower limb predominance as the port of entry could be explained by the fact that C. tetani exists in soil; hence, any lower limb injury would be open to contamination and infection by this organism. Based on the Dakar and Phillips score system, tetanus has a worse prognosis when there is a faster incubation period, faster onset, more proximal port of entry location, immunization status, comorbidities and signs of muscle spasm, fever, and tachycardia are obtained. Conclusion: In this study, tetanus still has a high mortality rate. Male gender, age over 45, a moderate to severe disease degree (considering a relatively short incubation time, short onset period, and unknown immunization status) are a few factors that may affect this high mortality rate.

Effectiveness of the Topical Application of 4% Chlorhexidine on Umbilical Cord Bacterial Colonization – A Non-Randomized Control Study

Newborns have the highest risk of death in the first 4 weeks of their life. Umbilical cord of a child is an important site for microorganism colonization and also forms a portal of entry for invasive pathogens. This study focuses on the bacterial colonization with 2 separate cord care regimens: dry cord and 4% chlorhexidine care group. This is a randomized control time-bound study conducted at a tertiary health care centre in Mangalore. A total of 144 newborns fulfilling the inclusion criteria were included and then divided randomly into two groups: dry cord care and 4% chlorhexidine. Two swabs were collected, baseline swab (swab 1) within 3 hours of birth and second swab (swab 2) at 120± 10 hours of birth and these samples were cultured for gram negative and positive organisms. Results were evaluvated with Chi-Square test. Out of 144 samples, in 115 showed no growth at the baseline and only 29 showed growth. In the dry cord care group, 38.9% showed growth of microorganism in comparison with chlorhexidine group which was 1.4% in swab 1 (baseline) and in swab 2, 87.5% in dry cord care group and 18.1% in chlrohexidine group in swab 2 respectively. It was observed that methicilin susceptible Staphylococcus aureus (MSSA) and methicillin resistant Staphylococcus aureus (MRSA) were the most common microorganisms isolated with others being Pseudomonas species, coagulase-negative Staphylococci (CoNS), Enterobacter species and Citrobacter species. Use of 4% chlorhexidine is effective in reducing colonization of bacteria and infection in comparison with dry cord care method. Therefore, decontamination of the umbilical cord with 4% of chlorhexidine should be recommended in a newborn child. However, both cord care methods did not lead to any infections.

The pathology of canine mammary candidiasis with embolic dissemination in a dog

Candidiasis is a fungal disease caused by Candida albicans or other members of the genus Candida. Descriptions of candidiasis are comparatively reduced in veterinary relative to human medicine, with no cases of mammary candidiasis being identified in pet animals. This report presents the cytological, pathological, and molecular findings of mammary candidiasis with embolic dissemination in a postpartum dog. A 1-year-old, female Shih-tzu dog that had recently given birth was admitted to a veterinary teaching hospital in Southern Brazil after repeated episodes of intermittent mammary disease and a neurological syndrome. The dog was euthanized due to worsened clinical status and poor prognosis despite adequate clinical therapy and was submitted for routine post-mortem evaluation to determine the cause of the neurological manifestations. Cytological analysis of purulent mastitis identified intralesional fungal hyphae. Gross evaluation revealed multiple masses within the kidneys, liver, myocardium, pancreas, and brain. Routine histopathology and histochemistry identified fungal nephritis, hepatitis, myocarditis, pancreatitis, and encephalitis associated with intralesional fungal hyphae, frequently with fungal emboli and vasculitis. Pure cultures of C. albicans were obtained from fragments of the masses observed at the myocardium and kidneys, with the typical germ tube of C. albicans being identified by microscopic evaluation. A PCR assay that targeted the ITS1 and 4 generic regions of fungi, amplified the desired amplicon, and direct sequencing confirmed C. albicans. Immunohistochemical and molecular assays designed to identify common infectious disease pathogens of dogs did not confirm the participation of canine distemper virus, canine parvovirus, or canine adenovirus in the target tissues of this dog. These findings suggest that this dog suffered an initial cutaneous lesion, that probably served as portal of entry to the mammary gland, resulting in mammary candidiasis with subsequent embolic dissemination to multiple organs. This report represent the first description of mammary candidiasis in pet animals and probably one of the few pathological descriptions of mammary candidiasis in domestic animals. In this case, the cause of the fungal infection was probably associated with factors intrinsic to abdominal surgery, pregnancy, and the utilization of antibiotics.

Rapid Detection of Phytophthora cambivora Using Recombinase Polymerase Amplification Combined with CRISPR/Cas12a

Phytophthora cambivora is a major quarantine pathogen that devastates economically important plants across the globe. P. cambivora causes ink disease in chestnut trees and root and stem rot in various fruit trees, resulting in significant yield reductions and plant death. Given the potential dangers of P. cambivora, effective detection methods are needed for both disease management and prevention. In this study, based on the whole-genome screening of specific target genes, a combination of the recombinase polymerase amplification technique (RPA) and CRISPR/Cas12 was established to detect P. cambivora. The RPA-CRISPR/Cas12a assay was able to specifically detect 7 target isolates of P. cambivora but did not detect the following 68 non-target isolates, including 28 isolates of Phytophthora, 3 isolates of Pythium, 3 isolates of Phytopythium, 32 isolates of fungi, and 2 isolates of Bursaphelenchus. The RPA-CRISPR/Cas12a detection method was able to detect 10 pg·μL−1 of P. cambivora genomic DNA at 37 °C within a short time span (60 min). Additionally, this method can identify the presence of P. cambivora in artificially inoculated apple fruits. In summary, compared with conventional detection techniques, the RPA-CRISPR/Cas12a detection method eliminates the need for expensive instruments, long reaction times, and high amounts of raw materials and can detect P. cambivora in imported plants at entry ports, enabling instant prevention and detection.

Data synthesis improves detection of radiation sources in urban environments

Radiation detectors in and around airports and other ports of entry play a crucial role in preventing nuclear terrorism. While these systems aim to detect and intercept nuclear materials before they enter a country, they are not foolproof. To address this, distributed sensors have been proposed to detect nuclear materials if they enter urban areas. Past work on small detector systems has shown that data fusion can improve detection. Here, we show how this could be done for a large detector network using Pearson's Method. We evaluate how a sensor network would perform in New York City using a combination of radiation transport and geographic information systems. We use OpenStreetMap data to construct a grid over the streets and analyze vehicle paths using pickup and drop off data from the New York State Department of Transportation. The results show that data synthesis in a large network (40 k detectors) not only improves the time to the first detection but reduces the number of missed sources by up to 99 %.

Microbiological Profiles and Inflammatory Biomarkers of Bacteremia in Children in a Teaching Hospital in Kuwait: An 8-Year Retrospective Study

Objectives: The objectives of this study were to determine the bacterial profiles and prevalence of antibiotic resistance patterns of bacteria causing bacteremia in febrile children and to compare levels of inflammatory markers between children with and without bacteremia in Kuwait from 2015 to 2022. Materials and Methods: Isolates from all episodes of significant bacteremia (n = 96) during the study period were recorded and evaluated. Microorganisms were identified using standard microbiological methods. Antimicrobial susceptibility testing was carried out using the VITEK2 system and Etest method. Extended-spectrum β-lactamase (ESBL) production by Enterobacterales was detected by the double-disk diffusion method and VITEK2 system. Patient age, gender, and inflammatory markers were collected at admission and compared between patients with and without bacteremia. Results: A majority of the patients were infants (37, 40%) and newborns (13, 14%). The main ports of entry were the lower respiratory tract, the genitourinary tract, and the gastrointestinal tract. Streptococcus pneumoniae was the most common pathogen (16, 16.7%) followed by Escherichia coli (12, 12.5%), Staphylococcus aureus (10, 10.4%), and Streptococcus agalactiae (9, 9.4%). High rates of resistance to ampicillin, cefuroxime, ciprofloxacin, and trimethoprim-sulfamethoxazole were observed among the Enterobacterales. The prevalence of ESBL-producing E. coli and K. pneumoniae were 45% and 29%, respectively. The prevalence of methicillin-resistant S. aureus was 30%. Patients with bacteremia had significantly higher white blood cell (WBC) counts, absolute neutrophil count (ANC), C-reactive protein (CRP), and neutrophil-lymphocyte ratio (NLR). Conclusion: Continuous surveillance of the prevalence and antimicrobial susceptibility patterns of blood isolates is imperative for the formulation of antibiotic policy. WBC, ANC, CRP, and NLR could be valuable indicators of bacteremia in febrile children.

Are changes in mothers’ representations of their infants related to changes in observed mother–infant interaction quality?

Infant mental health clinicians aiming to improve mother–infant dyads at risk typically target mothers’ representations of their infant or mother–infant interactions, assuming that one port of entry leads to change in the other. However, little is known about the relation between changes in mothers’ representations and in mother–infant interactions. Therefore, the current study aimed to investigate this in a low- to moderate-risk community sample of 152 mothers (M = 29.7 years) of infants aged 0–2 years (M = 11.5 months) recruited from rural and urban cities in Norway. The mothers’ representations were measured using the Working Model of the Child Interview, and the quality of the mother–infant interactions was measured with the Emotional Availability Scales. We found no evidence of a relation between mothers’ changed representations and changed quality of mother–infant interactions. Several explanations concerning the low-risk status of the sample, the observation situation, the time between assessment points, and the homogeneous scores from the instruments used are discussed, as are the implications for clinical practice and future research.
