Prevalence of bacterial isolates and change in their antibiotic susceptibility patterns in urinary tract infections- A five year retrospective study
Authors: Prabhala Srujana , Sundaresan Aarthi , Varaiya Ami
Published: January 2024

Urinary Tract Infection (UTI) continues to be one of the commonly occurring infections in medical practice despite the widespread availability of antibiotics. Presence of risk factors like elderly age, diabetes, immune-suppression, and other comorbidity pose a challenge in its treatment. Over the years, the etiology and antibiotic resistance of the uropathogens has been inconsistent. Therefore, it is important to determine the causative agents of UTI and their resistance patterns locally, in each region, so that appropriate empiric therapy can be started before the culture and antibiotic sensitivity results are available.

This study aims to highlight the prevalence of uropathogens and determine the antibiotic sensitivity pattern over the period of five years.

The urine samples from patients with suspected urinary tract infections (UTI) received in the laboratory at Nanavati Max Super speciality hospital were processed by standard protocol from January 2018 to December 2022. Antibiotic susceptibility test for the bacterial isolates was carried out by the VITEK2 automated system and interpreted as per CLSI guidelines. The data collected over the study period of five years was interpreted by using the WHO Net Antibiotic Susceptibility Surveillance Software in February 2023.

From a total of 8068 urine samples received over five years, uropathogens were isolated in 4209 (52.16%) samples. E.coli was the most common isolate causing UTI, with prevalence of 380(46.7%) in 2018 and 480(50.6%) in 2022 of total samples. Amongst gram positive organisms, a rise in Enterococcus species was seen from 41(5%) in 2018 to 87(9%) in 2022, with significantly fewer Staphylococcus species isolated, from 32(4%) in 2018 to 7(0.7%) in 2022.

The Enterobacteriaceae showed high sensitivity to Amikacin, Tigecycline and Meropenem all throughout the study. However, rise in resistance to Nitrofurantoin and Fosfomycin, antibiotics commonly used for UTIs, was observed. Also the prevalence of Extended Spectrum of Beta lactamase (ESBL) producers decreased from 213(36%) to 127(17%) with a rise in Carbapenemase producing Enterobacteriaceae from 48(8%) to 298(40%) over the five years study period.

Amongst Lactose Nonfermenting gram negative bacilli only 32 % were sensitive to Carbapenems and 37% sensitive to Aminoglycosides.

By 2022, Enterococcus species showed an increase in sensitivity to Nitrofurantoin (27%), High level Aminoglycosides (37%), Fluoroquinolones (25%) and Ampicillin (37%).

The change in antibiotic sensitivity patterns over time and rise in resistance to antibiotics commonly used in empirical treatment of UTIs warrants the need for regular surveillance, so the physicians can be updated regarding the most prevalent organism and its susceptibility and the empirical treatment for UTIs can be modified accordingly. This can help curb indiscriminate use of antibiotics and development of antibiotic resistance.

Ectopic Pregnancy (EP) is reported to be causative of high incidence of maternal death and morbidity. It must be diagnosed during the first trimester immediately after symptoms of severe bleeding, abdominal pain, and cramping. Ultrasonography is the only possible detection method to confirm EP. Patients are at greater risk of EP due to inefficient early detection methods. An early detection of the EP based on cellular markers would possibly improve the diagnosis and clinical management. Therefore, an attempt was made to study the histoarchitecture of, and to identify the biomarkers in, the fallopian tube during rupture of ectopic pregnancy. Histological analysis revealed the formation of hematosalpinx and hydrosalpinx in the fallopian tube. Further, immunohistochemical study of the fallopian tissue of EP patients showed remarkable evidence of protein markers such as Bcl2 and desmin which may be considered as potential cellular markers for the detection of EP.

Published: January 2024

Background: Endometriosis is a chronic inflammatory condition of high incidence and with serious consequences. Several synthetic compounds proved to be useful in treating its symptoms by inhibiting aromatase, which is responsible for the pathogenesis of this painful illness. Nevertheless, synthetic drugs inflict several side effects, including headaches, osteoporosis, and so on. This scenario advocates the search for therapeutic formulations based on natural compounds. Thus, the present study was hypothesized to evaluate the comparative efficacy of the synthetic and natural drugs used in endometriosis, using the bioinformatics approach. Methods: CB-Dock was employed to perform molecular docking of the aromatase enzyme with two synthetic and three natural drugs for predicting their molecular interactions, and binding affinities. The curcumin-aromatase complex was further subjected to MD simulations to determine its stability, and to apply it to natural compound-based computer-aided drug discovery. Results: Curcumin was observed to dock with a greater binding interaction with aromatase. The RMSD profile, hydrogen bonds, and the RMSF and Rg values of the complex were stabilised after 50 ns, which was an indicator of the stable binding pose of the curcumin-aromatase complex. Conclusion: These in-silico findings are the basis for proposing that curcumin can be considered as a potential binding agent to inhibit the aromatase enzyme in the treatment of endometriosis. Molecular modelling and dynamics results suggest that curcumin and aromatase form a stable complex and that curcumin can be targeted as a drug in the treatment of endometriosis
Adipose Tissue Dysfunction in PCOS
Authors: Aparupa Ananya , Singh Rita
Published: January 2024

Polycystic Ovary Syndrome (PCOS) is one of the most common endocrine diseases among women of reproductive age; however, its aetiology is unclear. PCOS is linked to many metabolic manifestations and alterations such as obesity, insulin resistance, and cardiovascular diseases (CVD). Women with PCOS have intra-ovarian and systemic changes in their metabolite levels. Adipose tissue dysfunction plays a significant role in the pathophysiology of PCOS. Adipose tissue growth is disrupted by metabolic stress, leading to hypertrophy of adipocytes, which begin to express stress signals. Adipose tissue secretes autocrine and paracrine factors, called adipokines or adipocytokines. Adiponectin is an adipocyte-derived protein abundant in the bloodstream. Plasma adiponectin concentration is low in women with PCOS, obesity, CVD, and hypertension. Other adipocytokines with altered secretion in PCOS include leptin, resistin, apelin, visfatin, IL-6, IL-8, and TNF-α. Hormonal imbalance, untimely action of high LH, and consequent hyperandrogenism in women with PCOS may cause metabolic defects associated with adipose tissue dysfunction; however, there are no reports on the role of higher LH levels in adipose dysfunction and altered adipokine secretion. New medications with therapeutic potential have been developed that target adipokines for the treatment of PCOS. This review discusses the association between PCOS and altered adipokine production as a consequence of adipose dysfunction.

The dietary protein, tryptophan, carbohydrate, and oil content of fish feed has many vital roles in the growth performances, stress management, and digestive physiology of fish. However, in this context, the functions of gut melatonin, which depends on the availability of food, timing of food supply, frequency of feeds/day, quality of food, and growth stages of carp, still need to be clarified. The present study aimed to investigate the impact of different experimental diets on growth performances, melatonin, oxidative stress and its essential antioxidants in the gut, and vital digestive enzymes of juvenile carp, Catla catla (mean body weight ~50g). The fish were fed any one of the seven diets viz. (i) a standard diet (SD/control) (with 34.99% protein, 14.56% carbohydrate, 9.84% oil, and 0.36% L-tryptophan) (ii) two protein (PRD1 with 41.02%, and PRD2 with 50.55% protein), (iii) two L-tryptophan (TrpRD1 with 0.96%, and TrpRD2 with 1.36% tryptophan), (iv) one carbohydrate (CRD with 24.62% carbohydrate), and (v) one oil (ORD with 14.68% oil) - rich diets for 30 days. Results indicated that the growth performance was better in PRDs, TrpRDs, and CRD compared to SD but not in ORD-fed carp. Further, PRDs and TrpRDs stimulated gut melatonin and suppressed oxidative stress by enhancing all the studied antioxidant levels. Upregulated digestive enzyme activities were also recorded after the PRDs and TrpRDs supply. However, CRD and ORD-fed groups exhibit less/no impact on most studied parameters, except digestive physiology. Nonetheless, the current study reports for the first time that PRDs and TrpRDs can modulate gut melatonin, oxidative stress, different antioxidants, and digestive efficacy.

Methods: A retrospective study with clinical and epidemiological data from patients was conducted on 314 children who attended Pediatric Department, Haematology-Oncology Unit, Menoufia University Hospital during the last fifteen years.
Results: 314 children were assessed, their ages ranged from 2 months-18 years with mean 5.96±3.79 years. Also, 252 (80.3%) were diagnosed with hematological malignancies, and 62 (19.5%) were diagnosed with solid tumors. Among hematological malignancies, 186 were diagnosed with acute leukemia, 158 (49.7%) with acute lymphoblastic leukemia (ALL), and 28 (8.8%) with acute myeloid leukemia (AML). The most frequent clinical presentations were fever in 95.24% in hematological malignancies vs 48.4% in solid (p<0.001),, pallor in 92.5% in hematological malignancies vs 69.4% in solid (p<0.001), hepatomegaly in 81.3% in hematological malignancies vs 37.1% in solid (p<0.001),, lymphadenopathy in 77.6 % in hematological malignancies vs 24.2% in solid (p<0.001), and splenomegaly in 76.3% of hematological malignancies vs 12.9% in solid (p<0.001),The majority of the patients 64.15% had white blood cells (WBCs) less than 50,000/mm³, while 35.85% had WBCs more or equal to 50,000/mm³ with significant relation with risk stratification (p=0.001). The survivors who finished their treatment course were 31.8% and the recurence patients were 9%.
Conclusion: Acute lymphoblastic leukemia is the most frequent childhood hematological neoplasm. Various clinical and laboratory features present at the time of initial diagnosis can predict the likelihood that a patient will remain in remission or not including age: under 1 and over 10 years, gender: male sex, WBCS more than 50,000/mm³ at presentation.
Risk factors of Second Malignant Neoplasms in Childhood Cancer Survivors
Authors: Bahrami Mahshid , Sheikhpour Elnaz , Karami Mojtaba , Mehrabani Sanaz
Published: January 2024

Cancer is as the second leading cause of death among children in the United States. The mortality rate for cancer has witnessed a decline, dropping from 6.5 per 100,000 in 1970 to 2.3 per 100,000 in 2016. Second malignant neoplasms (SMNs) represent novel primary malignancies emerging after the initial cancer diagnosis, particularly prominent as late effects of cancer therapy in children. The incidence of SMNs sees a substantial increase over time, reaching nearly 10% even a decade after the initial diagnosis. A comparative analysis between the general population and child cancer survivors reveals a six-fold higher risk of developing SMNs among the latter. Various factors contribute to the elevated risk of second cancers, with age, lifestyle, environmental influences, primary cancer treatment, and genetic predisposition playing pivotal roles. Noteworthy risk factors for SMNs in children encompass radiation therapy, chemotherapeutic agents, topoisomerase inhibitors, genetic factors, hematopoietic stem cell transplantation, and ionizing radiation, as elucidated in the present study. Despite these findings, further research is imperative to accurately quantify the risks associated with etiological factors, enabling the identification of individuals at a heightened risk for second cancers and facilitating proactive screening and preventive measures.

Rapid rising in radiative forcing
Authors: Wu Chenwu
Published: January 2024

The energy balance between the earth (and its atmosphere) absorbing solar radiation and its radiation into space determines the equilibrium temperature of the earth’s surface. The process of the earth and its atmosphere as a whole radiating long-wave electromagnetic waves into space includes the transmission of surface radiation by the atmosphere, absorption, reflection, reverse radiation, and atmospheric radiation to space, etc. When the concentration of greenhouse gases such as CO2 in the atmosphere changes, the absorption of surface radiation by the atmosphere also changes immediately, thereby changing the equilibrium temperature of the atmosphere and the surface. The relationship between equilibrium temperature and atmospheric CO2 content, or so-called the earth’s climate sensitivity, is a focus of climate dynamics research.

Meta-analysis of transcriptomic data from different experiments has become increasingly prevalent due to a significantly increasing number of genome-wide experiments investigating gene expression changes under various conditions. Such data integration provides greater accuracy in identifying candidate genes and allows testing new hypotheses, which could not be validated in individual studies. To increase the relevance of experiment integration, it is necessary to optimize the selection of experiments. In this paper, we propose a set of quantitative indicators for a comprehensive comparative description of transcriptomic data. These indicators can be easily visualized and interpreted. They include the number of differentially expressed genes (DEGs), the proportion of experiment-specific (unique) DEGs in each data set, the pairwise similarity of experiments in DEG composition and the homogeneity of DEG profiles. For automatic calculation and visualization of these indicators, we have developed the program InterTransViewer. We have used InterTransViewer to comparatively describe 23 auxin- and 16 ethylene- or 1-aminocyclopropane-1-carboxylic acid (ACC)-induced transcriptomes in Arabidopsis thaliana L. We have demonstrated that analysis of the characteristics of individual DEG profiles and their pairwise comparisons based on DEG composition allow the user to rank experiments in the context of each other, assess the tendency towards their integration or segregation, and generate hypotheses about the influence of non-target factors on the transcriptional response. As a result, InterTransViewer identifies potentially homogeneous groups of experiments. Subsequent estimation of the profile homogeneity within these groups using resampling and setting a significance threshold helps to decide whether these data are appropriate for meta-analysis. Overall, InterTransViewer makes it possible to efficiently select experiments for meta-analysis depending on its task and methods.

Published: January 2024

Background: Inclusion of legume crops in efficient cropping system is important to maintain soil bio-physical property for sustainable production systems. Conservation agriculture (CA) practices have been demonstrated to be successful in cereal based systems. But the information on zero-tillage as CA practice in legume based systems is lacking, which may further help in conservation of soil resources on sustainable basis. Hence study on impact of zero-tillage on soil biological and physico-chemical properties was undertaken at CCS Haryana Agricultural University, Regional Research Station, Bawal (Rewari), India during 2019-20 and 2020-21. Methods: The soil of experimental site was loamy sand in texture and low in organic carbon, N and P, while medium in K. The treatments included nine tillage combinations for crop establishment under mung bean [Vigna radiata (L.) Wilczek]-wheat (Triticum aestivum L.) cropping system (MWCS) viz., Zero-tillage mung bean (ZTM) fb zero-tillage wheat (ZTW), ZTM fb reduced tillage wheat (RTW), ZTM fb conventional tillage wheat (CTW), reduced tillage mung bean (RTM) fb ZTW, RTM fb RTW, RTM fb CTW, Conventional tillage mung bean (CTM) fb ZTW, CTM fb RTW, CTM fb CTW. The experiment was laid out in randomized block design with three replications. Result: After two years, there was no change in soil texture and EC of the soil due to different crop establishment methods, while the bulk density of upper soil layer (0-15 cm) decreased marginally under system-based ZT method. The Infiltration rate increased with decrease in the frequency of tillage in both the crops. Organic carbon in upper layer increased while pH decreased marginally under ZTM-ZTW as compared to CTM-CTW. Available N and P showed increasing trend with decrease in number of tillage operations after two years of MWCS. Tillage practices had no significant effect on available K. The grain yield of wheat was not influenced by tillage during 2019-20, but in 2020-21 it was significantly higher under ZT wheat sown after ZTM (5025 kg ha-1) than RTW (4622-4722 kg ha-1) and CTW (4593-4641 kg ha-1), irrespective of tillage practices in mung bean. The seed, stover and biological yields of mung bean were similar under all crop establishment methods in MWCS. This indicated sustainability of zero-tillage methods of establishment in MWCS.
Impact des politiques foncières sur la typologie d’élevage et la dynamique des parcours steppiques dans la région de Naâma (ouest algérien)

Published: January 2024

À l’instar des zones steppiques, l’organisation foncière de la région de Naâma (ouest algérien) a connu des changements et des bouleversements profonds depuis des siècles. La genèse du régime foncier actuel est le produit des conditions historiques lors de trois époques successives : la période ottomane (avant 1830), la période coloniale (1830-1962) et l’Algérie indépendante (après 1962). L’objectif de cette étude est de comprendre l’impact des politiques foncières récentes des soixante dernières années de l’Algérie indépendante sur les modes et les systèmes d’élevage en milieu pastoral, ainsi que sur l’organisation et la dynamique des parcours steppiques de la région de Naâma. Une enquête de terrain a été réalisée auprès des détenteurs du cheptel dont les activités et les pratiques sont supposées être des facteurs déterminants de la modification du paysage steppique. Les résultats révèlent que l’appropriation, la mise en valeur des terres et la sédentarisation soutenues par les pouvoirs publics, suivent une tendance croissante et ont pour conséquences de fragmenter l’immensité steppique et d’affecter les modes et les systèmes d’élevage. Pour atténuer le changement et le bouleversement de l’espace steppique, des mesures urgentes doivent être mises en place autour de deux grands axes : l’instauration d’un plan d’occupation des espaces steppiques proprement dits, et la mise en place de mesures juridiques nécessaires pour récupérer les terres détournées et mettre fin aux pratiques inadaptées.

The Biosite Pangpang Bay Ijen Geopark (BPBIG) has a high potential biodiversity value outside the conservation area, particularly in the mangrove forest. Namun informasi keragaman ini masih belum sepenuhnya lengkap. Sehingga penelitian ini bertujuan untuk menentukan keragaman jenis burung di hutan mangrove BPBIG. The research was conducted on October 2023 using the point count method at six observation points in the mangrove forest. Data analysis was carried out in two approaches, i.e., species composition and species diversity index using Shannon Wiener index (H’). We recorded 39 bird species, consisting of 32 genera and 21 families, in the mangrove forest of BPBIG. There is one bird species that has important conservation status based on the IUCN Red List and National Regulation, namely L. javanicus (a vulnerable and protected species). Furthermore, there are also three migratory birds (T. sanctus, N. phaeopus, and A. hypoleucos) that use the mangrove forest of BPBIG as stopover sites during migration periods. The results of the Shannon Wiener index showed that the bird diversity in the BPBIG mangrove ecosystem is in the medium category (H' = 2.02). Finally, based on these results, it can be concluded that the bird species in the mangrove forest of BPBIG are quite diverse.

Narta Lagoon is one of the biggest Lagoons in Albania. It is situated in the southern part of the Vjosa River delta. Two canals in the northwest and southwest parts of the lagoon connect it to the Adriatic Sea. These artificial canals enable the water exchange process with the sea during tidal flow. Vjose - Narta area is considered a Protected Landscape, so environmental monitoring is important. Setting and design: Water samples were taken monthly, at six evenly distributed sample stations. The study was conducted from January – to December 2018. Materials and methods: The assessment of microbial contamination was performed with the MPN method. Total coliform, fecal coliform, and fecal streptococci were tested as fecal contamination indicators. PH and salinity were the physicochemical parameters analyzed. Conclusions: the cleanest sampling station is the one near contact with the seawater. The most polluted stations are stations 2, 4, and 6. Temperature values range from 5 oC in January to 33 oC in August. Lagoon pollution is caused by an anthropogenic factor as well as a lack of appropriate cleaning strategies.

Oxygen has been shown able to be released from aqueous water when the water flows through magnetic fields. Such a production process is called magneto synthesis and it is successful when the principle of induced current took place. Oxygen produced from this newly discovered process possessed properties differently when compared to the photosynthesis process. This study can be made when the magneto synthesis process was carried out closed to the saturation point of oxygen dissolution equilibrium in aqueous water. At the saturation point, the exchange of oxygen atoms or molecules between these two processes has happened. This interchange state allowed a unique single steep-drop characteristic to be observed. The single steep-drop characteristic of the magneto synthesis process provides two pieces of evidence on the properties of oxygen; they are heavier by mass and higher by oxidative power. The unique properties as discovered are supported by Einstein’s Special Relativity Theory. In this matter, gamma-ray flashes are thought to produce when the hydrogen-electron pairs are formed. A mechanism where gamma-ray flashes could be produced was proposed and sufficient evidence for gamma-ray flashes to occur was outlined. The gamma-ray flashes are the clue in the inter-permutable between the mass and energy. This is the clue to let the special relativity theory take a place.

Published: January 2024

Mechanical activation of Ca/Mg silicates by grinding is a pre-treatment of some mineral carbonization processes. In this study, the mechanical activation of lizardite ore from a chromite beneficiation plant waste by grinding in a stirred media mill was studied. For grinding studies, grinding times of 10-20-30 min and stirring speeds of 600-800-1000-1200 rpm were the parameters investigated, while the ball charge rate was 60% and the ore charge rate was kept constant at 40%. This way, the effects of grinding time and stirring speed on particle size distribution and energy consumption were investigated. At the end of the grinding studies, the stirring speed was determined as 1200 rpm, and the grinding time was 10 min for the finer particle size distribution (d10: 2,7 µm, d50: 13,6 µm, d90: 57.6 µm) with less energy consumption (130.4 kWh/ton). FT-IR analyses proved that the samples were dehydroxylated by the milling process. As a result, according to the analysis performed after grinding, it can be said that the finer product obtained can be used in mineral carbonation processes.

Published: January 2024

To improve both the critical scratch load and micro-hardness of (Al, Cr) N coating film, (Al, Cr, W) N coating film was developed. In this study, to clarify the tool wear of the coated tool in the cutting of sintered steel using four types of (Al, Cr, W) N coated tools, the wear progress and the wear mechanism of the coating film were investigated. By using two types of the (Al, Cr, W)-target and three types of bias voltage, the (Al, Cr, W) N coating film was deposited on cemented carbide ISO K10. To clarify the wear mechanism of the (Al, Cr, W) N coating films, scanning electron microscope (SEM) observation and Energy Dispersive X-ray spectrometry (EDS) mapping analysis of the abraded coating film were performed. The cutting conditions were a cutting speed of 3.33 m/s, feed rate of 0.1 mm/rev, and cutting depth of 0.1 mm. The following results were obtained: (1) The wear progress of the (Al64, Cr28, W8) N coated tool was slower than that of the (Al60, Cr25, W15) N coated tool. (2) When nitride coating films were deposited on the cemented carbide ISO K10 with a bias voltage of -80 V, -150 V, or -300 V using the (Al64, Cr28, W8)-target, the wear progress of the (Al64, Cr28, W8) N coated tool with a bias voltage of -80 V was the slowest.

A questão dos letramentos e da inovação demonstram-se fundamentais em períodos históricos como o atual, onde as práticas de ensino-aprendizagem tornam-se cada vez mais complexas, que requerem novas abordagens teóricas para compreendermos possibilidades alternativas de ensino. Tendo estas questões em mente, este artigo visa indicar relações possíveis entre o antifundacionismo, o pensamento de Paul Feyerabend e os letramentos científicos. Em um primeiro momento indicaremos questões relativas ao antifundacionismo, e em seguida verificaremos como tal questão se efetiva no pensamento de Feyerabend. Finalizaremos avaliando como esta abordagem pode fundamentar novas práticas educacionais.
A paideia de Habermas nas entrelinhas de sua teoria crítica da racionalidade moderna
Authors: Ferreira Diego Augusto Gonçalves , Miranda Eduardo Soncini
Published: January 2024

Este artigo busca encontrar na teoria crítica da racionalidade moderna de Jürgen Habermas (1929-) elementos de uma paideia. O primeiro tópico lança o substrato epistemológico sobre a existência das racionalidades estratégica e comunicativa. O segundo, afirma que o desengate entre o sistema e o mundo da vida, e a colonização deste por aquele, causam as patologias modernas e colaboram para a formulação de pedagogias coordenadas pela ação estratégica. O terceiro, propõe que o reacoplamento do sistema ao mundo vivido proporciona que todas as dimensões da existência humana sejam orientadas pela ação comunicativa, na qual se encontram os traços de uma paideia emancipadora e revolucionária.

ABSTRACTGrowth failure process started since the child was still in the womb. The success of growth process is determined by feeding practices. A total of 59% of Indonesian children aged 6-23 months were given food that inappropriate with the recommendations of timing, frequency, and quality. The lack of proper feeding can be reduced by providing intervention in the form of counseling to mothers. The aim of the study was to analyze the growth and feeding counseling towards knowledge and attitudes about feeding in the area of Brambang Public Health Center, Jombang district. The study design was quasi-experimental. Samples were children aged 6-24 months with malnutrition and over nutrition. Respondents were 12 mothers of malnutrition and overnutrition children in each group. The control group was given a leaflet about eating guideline for children, health care “KMS”, and nutrition-conscious family “Kadarzi”, whereas the intervention group was given leaflet and growth-feeding counseling. The counseling was given once a month for 15-20 minutes over three months. Wilcoxon Sign Rank test was used to analyze before-after differences in knowledge and attitudes. The result showed that there was a difference in the level of knowledge in intervention group (p=0,005) and control group (p=0,0250). There was also a difference of attitude in intervention group before-after intervention (p=0,014) but not in the control group (p=0,317). The growth and feeding counseling could increase the knowledge and attitude of mothers about nutrition. The counseling should be given regularly and further effort to assess others factors beyond nutrition is needed for more effective results.Keywords: attitude, counseling, knowledge, weaning food

Children under five is a group that vulnerable to undernutrition, particularly wasting and stunting. Wasting and stunting are common happened in poor families. One cause of wasting and stunting is related to mother care pattern to their child. Mother care pattern is associated to maternal education and knowledge level. Mothers with low education will be more difficult to receive information compared to mothers with higher education. Less knowledge mother may affect poor caring pattern, therefore it could induce wasting and stunting problem in children under five. The aim of this research was to analyze correlation between the level of education, knowledge, and mother’s care pattern with wasting and stunting. The sample was 47 children from poor families in Balen, Bojonegoro that selected using simple random sampling technique. Data were analyzed using chi-square test with α=0,05. The result of the research showed that in poor families, percentage of stunting was higher than wasting and there was no correlation between level of education (p=0,581 and 0,605), level of knowledge (p=0,632 and 0,963), and mother’s care pattern (p=0,719, and 0,928) with wasting and stunting. This study concluded that the level of education, knowledge, and mother’s care pattern do not contribute to the occurrence of wasting and stunting problem among children under five from poor families in Balen, Bojonegoro. The government should strive to increase mother’s and pregnant women’s knowledge about balanced nutrition, child health, and child nutritional problem to prevent wasting and stunting through routine promotion and counselling by health professionals.Keywords: poverty, stunting, wasting

Antibiotics are frequently used arbitrarily in livestock industry without regards for dosage or norms use. The administration of antibiotics to livestock can lead to a decline in their efficacy and contribute to the emergence of antibiotic resistance, hence posing challenges to the quality and safety of livestock products. Escherichia coli (E.coli) is recognized as a bacterial indicator pollution. This study aims to determine the resistance of E. coli to the antibiotic’s penicillin G and tetracycline. The study used a survey method with cross-sectional study design in July, 2023 on farms located in West Lombok. Testing was carried out on 10 water samples taken from water sources on farms that showed 2 negative samples and 8 positive samples of E. coli on EMBA media, then continued with resistance tests using Penicillin G and Tetracycline antibiotics by measuring the inhibitory zone that formed. The results of this study showed that E.coli samples experienced resistance to Penicillin G as many as 8 samples and tetracycline as many as 6 samples. E.coli bacteria isolated from drinking water have experienced resistance to antibiotics Penicillin G by 100% and Tetracycline 75%.

A 7-year-old male Persian cat was referred to IPB University Veterinary Teaching Hospital with clinical signs of lethargy, weight loss, and loss of appetite and was diagnosed with nephrolithiasis before being referred to IPB University Veterinary Teaching Hospital. Physical examination revealed tachycardia, tachypnoea, pale mucous membrane, 5–6% dehydration rate, cachexia, and palpated masses on the left and right side of the abdominal region. The abdominal cavity was seen as more radiopaque, which resulted in some organs being invisible in the radiographic view. Abdominal ultrasonography showed abnormalities in the liver, gall bladder, and kidneys. The patient was diagnosed with polycystic kidney disease (PKD) with the prognosis of infausta, as the patient was already in a sternal recumbency and could not stand by himself. During hospitalization, the patient was force-fed with a commercial renal diet, and the medical treatments given were intravenous ceftriaxone, vitamins, furosemide, Azodyl®, and intravenous infusion. The patient regained standing ability and survived until the seventh day of hospitalization. However, the owner persisted in bringing the patient home on the seventh day of hospitalization, and the patient died the next day after being brought home.

A retrospective case-control study was conducted in dogs with bone fractures presented at the Veterinary Teaching Hospital - Diliman Station, Companion Animal Clinic, College of Veterinary Medicine, University of the Philippines Los Baños from January 2016 to December 2021. One hundred sixty-one dogs were diagnosed with bone fractures. Limping was the most common chief complaint with falling from a height being the most common cause. Close, complete, and oblique fractures were the most prevalent fracture type. Around 29.81% of the cases were given medications only and 16.77% were treated with external coaptation.  Among the cases treated with external coaptation, only fourteen came back for follow-up with fully healed bone fractures. The mean age of dogs with bone fractures was 2.30 years old and was seen as a significant risk factor regardless of age group. Dogs fed with dry dog food and table food were 0.35 and 0.50 less likely to have bone fractures, respectively. The body weight, body condition scores, and dog breeds were not significant risk factors while the abode of the animal was a significant risk factor regardless whether the animal is indoor or outdoor. Age, diet, and abode were found to be significantly associated with bone fractures.

Microvascular self-healing composite materials have significant potential for application and their mechanical properties need in-depth investigation. In this paper, tensile and compressive properties of woven fabric carbon fiber reinforced polymers (CFRP) laminates containing three-dimensional microvascular channels were investigated experimentally. Several detailed finite element (FE) models were established to simulate the mechanical behavior of the laminate and the effectiveness of different models were examined. The damage propagation process of the microvascular laminates and the influence of microvascular parameters were studied by the validated models. The results show that microvascular channels arranged along the thickness direction (z-direction) of the laminates are critical locations under the loads. The channels have minimal effect on the stiffness of the laminates but causing a certain reduction in strength, which varies approximately linearly with the z-direction channel diameter within its common design range of 0.1~1mm. It is necessary to consider the resin-rich region formed around microvascular channels in the warp and weft fiber yarns of the woven fabric composite when establishing the FE model. And the layers in model should be assigned with equivalent unidirectional ply material in order to calculate the mechanical properties of laminates correctly.

Published: January 2024

This article describes a novel electrochemical on-chip biosensor that utilizes anti-PSA antibody (Ab) and silver nanoparticles (AgNPs) to enhance the sensing and detection capability of prostate specific antigen (PSA) in the blood. The AgNPs are prepared, characterized, and applied onto a silicon photonic on-chip biosensing receptor platform designed to enhance the accurate detection of PSA. The AgNPs were synthesized by a chemical reduction method using silver nitrate (AgNO3) as the precursor. Transmission electron microscopy (TEM), selected area electron diffraction (SAED), energy dispersion X-ray spectroscopy (EDS), small angle X-ray scattering (SAXS), X-ray diffraction (XRD), and light microscopy were among the methods used in the characterization and analysis of the AgNPs. Each stage of the immunosensor fabrication was characterized using cyclic voltammetry. The proposed immunosensor was applied in the detection of PSA, a prostate cancer biomarker, with a high sensitivity and a limit of detection of 0.17 ng/mL over a linear concentration range of 2.5 to 11.0 ng/mL. The immunosensor displayed good stability and was selective in the presence of interfering species like immunoglobulin (Ig) in human serum, ascorbic acid (AA), and diclofenac (Dic). The detectivity and sensitivity are significantly higher than previous reports on similar or related technologies.
