INTRODUÇÃO: A erosão dentária caracteriza-se como uma condição multifatorial associada com a perda irreversível de estrutura dentária resultante de processo químico envolvendo fontes ácidas não bacterianas. Nos casos mais severos o grau de dano tecidual pode não raro provocar a redução da dimensão vertical de oclusão (DVO). O amplo desenvolvimento das técnicas adesivas tem favorecido a adoção de procedimentos mais conservadores com preservação de estrutura dentária hígida. OBJETIVO: Relatar um caso clínico de técnica aditiva minimamente invasiva para reanatomização de dentes anteriores superiores como parte integrante do restabelecimento de dimensão vertical de oclusão de arcadas danificadas pelo processo de erosão dentária. RELATO DO CASO: Paciente HGH, 42 anos, gênero feminino, apresentou com queixa de insatisfação com a aparência estética de seu sorriso. As imagens de face apresentam sinais característicos de uma dimensão vertical de oclusão reduzida, associada a desgaste generalizado dos dentes anteriores. Para a reanatomização da face palatal dos dentes 11,12,13, 22 e 23, bastante destruída, optou-se pela técnica aditiva de com resina composta direta associada à faceta cerâmica nas faces vestibular e incisal, conhecida como Técnica de Sanduíche. O emprego de uma matriz de silicone transparente possibilitou uma reprodução fiel, e tecnicamente mais simplificada, da anatomia palatal definida no enceramento. CONCLUSÃO: A técnica Sanduiche apresenta-se como alternativa segura, exequível e efetiva para o restabelecimento de DVO de arcadas severamente danificadas pelo processo de erosão dentária.
O legado hermenêutico do Círculo de Éranos para as Ciências da Religião

Published: November 2021

O artigo apresenta histórica e teoricamente o Círculo de Éranos como um modelo interpretativo para as Ciências da Religião. Trata-se, a rigor, de uma aproximação ao mesmo tempo histórica e temática ao Círculo de Éranos buscando as pluralidades nos encontros que pudessem contribuir à uma hermenêutica para as Ciências da Religião. Sabe-se que os encontros, inaugurados por Olga Fröbe-Kapteyn, colocou em conversa variados pensadores de áreas distintas, como Rudolf Otto, Carl Jung, Martin Buber, Paul Tillich, Jakob Hauer, Heinrich Zimmer, Karoly Kerenyi, Gershom Scholem, Henry Corbin e Mircea Eliade. Em uma tentativa incansável de aproximar Ocidente e Oriente, Jung, a título de contextualização, teve a oportunidade de modificar parte de suas teorias devido a convivência com os participantes, atribuindo, assim, uma renovada significação religiosa às suas reflexões. Além de Jung, Mircea Eliade, como um dos principais interlocutores com Jung, também contribuiu a respeito do significado da vida religiosa. Este artigo, portanto, busca recuperar a história do Círculo de Éranos e, ao invés de vasculhar o valor do Círculo de Éranos em si, pretende trabalhar a contribuição do Círculo de Éranos para a constituição da área das Ciências da Religião e Teologia pelo viés da linha de pesquisa Linguagens da Religião propondo uma base hermenêutica da pluralidade a partir de uma reinterpretação do significado da pesquisa em Ciências da Religião tendo no Éranos uma forma de spiritus rector original.

Caracterización médico legal del homicidio en víctimas femeninas
Authors: Estupiñan Rodriguez Norge , Machín Guevara Yaima , Monzón González Joel
Published: November 2021

El feminicidio define un acto de violencia extrema contra las mujeres por su condición de ser mujeres. Forma parte del concepto más amplio de violencia de género. El debate social que existe en la actualidad sobre la violencia contra la mujer ha tenido que producirse sobre una realidad ignorada. En esta polémica han sido más los que han buscado responsables que los que han aportado soluciones. La medicina en general y la medicina forense en particular han sido una víctima más de ese contexto socio-cultural que ha permitido que se produjera la agresión a la mujer de muy diversas formas por el hecho de ser mujer, sin que haya habido una respuesta científica similar a la que ha aparecido en otro tipo de hechos de violencia interpersonal. Este comportamiento ha sido más relevante en los países en vías de desarrollo; solo en Latinoamérica y el Caribe se reportan diariamente un aproximado de 1250 muertes de mujeres por día, como resultado de actos de violencia de género. Según la Organización de Naciones Unidas (ONU) 25 países concentran las mayores cifras de homicidio contra mujeres en el mundo, y 14 de estos pertenecen a América Latina y el Caribe. En Cuba a pesar de la existencia de violencia de género como en el resto de los países latinoamericanos no está tipificado este delito y la muerte de una mujer a manos de un hombre se trata jurídicamente como un homicidio indiferenciado.

El objetivo general de la investigación consistió en caracterizar los homicidios en victimas femeninas durante el período 2013-2018, tratados por el Servicio Provincial de Medicina Legal en Matanzas.

Se realizó un estudio descriptivo retrospectivo, analizando los dictámenes de necropsias realizadas a las víctimas de homicidios en el periodo de tiempo estudiado, utilizando un instrumento de recogida de datos creado para la investigación.

Se excluyeron los casos de féminas fallecidas en accidentes de tránsito o que encontraron la muerte a manos de otra mujer.

Published: November 2021

In this study, we discuss the structure and properties of high-entropy AlCoCrFeNi alloy after casting, cold deformation, and heat treatment. Ingots of the investigated alloys were obtained by arc melting method in argon atmosphere. In order to ensure a homogeneous chemical composition, ingots were remelted several times. Cylindrical samples of 5 mm in diameter and 8 mm in height were cut from ingots by electrospark method for mechanical tests. Subsequently, samples were subjected to uniaxial compression by 5, 11, and 23 %. During the tests, compression curves were recorded, and limit of proportionality of the analyzed alloys was calculated. High-temperature annealing and thermal studies were performed using thermogravimetric analyzer. Thermal studies were carried out in a cyclic mode (3 cycles, including heating up to 1200 °C at a rate of 20 °C/min and cooling at a rate of 20 °C/min). High-temperature annealing was carried out at a temperature of 1200 °C for 5 hours. Such annealing of cast alloys promotes material homogenization and eliminates dendritic structure. The alloy presents limited plasticity. Grain boundaries are effective barriers preventing crack propagation. The studies indicate that plastic deformation has a significant effect on development of relaxation processes during subsequent heat treatment. An increase in strain during the compression leads to a higher rate of healing processes of defects in crystal structure.

Published: November 2021

Today there is an urgency of creating high-performance continuous processes for the production of bimetals. The article describes the main tasks of improving the quality of the materials under consideration. Two stages of the technology for producing steel three-layer bimetallic strips on the unit of a combined continuous casting and deformation process are considered. The authors give recommendations on the conduct of the technological process in order to obtain high-quality bimetallic strips on such unit. The problem statement is presented. The material considers initial data for determining the temperature of the steel base strip and the stress-strain state of the metals of the cladding layers and the strip in deformation center of a three-layer bimetallic ingot. A model for calculating and a method for solving problems of thermal conductivity and elastoplasticity are shown. Regularities of the temperature change of the main steel strip are given during its passage through the molten metal of the cladding layer. Stress-strain state of the metals of the main strip and cladding layers in the deformation center was determined when three-layer bimetallic steel strips were obtained on the unit of combined continuous casting and deformation process. The authors describe the values of compression of the main steel strip and mutual displacement of the layers during compression of the bimetallic ingot by the strikers. Regularities of the distribution of axial and tangential stresses are shown along the contact line of the cladding layer with the striker. The evaluation of the process of obtaining bimetal steel 09G2S - steel 13KhFA - steel 09G2S was made on a pilot unit for continuous casting and deformation. Microstructure of the main strip and cladding layers of a three-layer bimetallic steel strip is shown when a combined continuous casting and deformation process is obtained in one unit.

Bioaccumulation and Human Risk Assessment of Heavy Metals in Oreochromis niloticus and Clarias gariepinus Fish Species from the Golinga Reservoir, Ghana
Authors: Naangmenyele Zita , Ncube Somandla , Akpabey Felix J. , Dube Simiso , Nindi Mathew M.
Published: November 2021

ABSTRACT The Nile tilapia (Oreochromis niloticus) and African catfish (Clarias gariepinus) from the Golinga reservoir in Northern Ghana are consumed as an alternative source of protein. In the current study, levels of selected metals (As, Cd, Fe, Co, Cr, Cu, Mn, Mo, Ni and Pb) in the two fish species and the fish condition were determined, and potential human health effects assessed. The metal concentrations in the edible fish muscles ranged from 0.16 mg kg-1 (Mn) to 101 mg kg-1 (Pb). The weight-length relationships showed that both fish were growing isometrically, and bioaccumulation of metals from the reservoir was considered insignificant with bioconcentration factors below 100 except for Mn, whose value was 161 in the gills of Oreochromis niloticus. The health risk assessment showed that Pb, Cd and As had Target Hazard Quotient values above 1 for both fish species, with that of As being as high as 19.6 for Oreochromis niloticus. The target cancer risk values for As, Cd, Cr and Pb were above the non-risk threshold of <10-6, indicating the risk of cancer developing over the years due to fish consumption. The metal concentration in the fish in the reservoir should therefore be constantly monitored and potential health risks associated with frequent consumption of the fish assessed.

Adsorption-Kinetic Studies of Mordant Exhaust Dyeing of Cotton and Silk Fabrics with Dye Extract of M. lucida Plant Species
Authors: Loum Janani , Byamukama Robert , Wanyama P.A.G.
Published: November 2021

ABSTRACT The kinetics and adsorption isotherms of the extremely slow traditional natural exhaust dyeing that takes many hours or days have been studied purposely to find means of improving the process. The dyeing of cotton and silk fabrics using dye extract of M. lucida at 50 °C were elucidated with graphs to predict the reaction orders and identify the appropriate adsorption isotherm model(s). Since the dye is UV active, changes in UV absorbance were used in place of changes in concentrations. The simultaneous and post mordanting methods followed pseudo-second-order reactions, hence chemisorption. However, mordant application to the dyed fabrics during post mordant followed a pseudo-first-order model, largely physisorption. Dyeing has followed Langmuir and Freundlich isotherm models with linear correlation r2 ranging between 1 and 0.998. From the Freundlich model and values of Langmuir constant RL (0.9307 to 1.0), the process is homogeneous, forming a favourable and linear monolayer. Accordingly, the dyeing speed can be improved by increasing the concentration of dye liquor. Additionally, according to the Freundlich model, higher dye intensity on fabrics is recorded in post mordanting. Keywords: adsorption isotherms, equilibrium, exhaust dyeing, mordant, rate law
Temperature and relative humidity trends in the northernmost region of South Africa, 1950–2016
Authors: Nyoni Njongenhle M.B. , Grab Stefan , Archer Emma , Malherbe Johan
Published: November 2021

The northernmost Limpopo Province is located in one of the warmest regions of South Africa, where the agricultural sector is prone to heat stress. The aim of this study was to explore air temperature and relative humidity trends for the region, which have implications for agricultural adaptation and management (amongst other sectors). In particular, we investigated seasonal, annual and decadal scale air temperature and relative humidity changes for the period 1950–2016. Positive temperature trends were recorded for this period, averaging +0.02 °C/year, with the strongest changes observed in mean maximum summer temperatures (+0.03 °C/year). Interannual temperature variability also increased over time, especially for the period 2010–2016, which presents probability densities of <50% for minimum temperatures. Positive relative humidity trends (+0.06%/year) were also recorded for the period 1980–2016, but proved to be the least predictable weather parameter, with probability densities of <0.5% across seasons for the study period. Considering the substantial interannual variability in temperature and relative humidity, there is clear increased risk for the agricultural sector, particularly for small-scale farmers who generally have limited capacity to adapt. Climate science focusing on the southern African region should continue to establish the impact of climate change and variability on specific small-scale farming systems and enterprises, with recommendations for strategic adaptation based on up-to-date evidence.Significance:

Heat indices have increased, and variability in temperature and relative humidity has substantially increased over recent decades.
Changes in air temperature and relative humidity have direct and/or indirect negative effects on sectors such as agriculture, leading to reduced productivity.
The small-scale farming sector, which contributes significantly to national food security in developing countries, is the production system most exposed and vulnerable to observed changes/extremes in temperature and relative humidity.
There is an urgent need to build capacity of small-scale farmers for appropriate adaptation to observed changes in climate based on up-to-date evidence.

Published: November 2021

The presence of Staphylococcus spp. has increasingly been reported in food products and poses a public health threat. The aim of this study was to determine the diversity of Staphylococcus spp. and the antibiotic resistance profiles of isolates obtained from freshly harvested and packed ready-to-eat mushrooms (n=432) and handlers’ hands (n=150). A total of 56 Staphylococcus isolates [46.4% (n=26) from hands and 53.6% (n=30) from mushrooms] were recovered belonging to 10 species. Staphylococcus succinus isolates (n=21) were the most prevalent, of which 52.4% came from mushrooms and 47.6% from hands. This was followed by S. equorum isolates [n=12; 91.7% (n=11) from mushrooms and 8.3% (n=1) from hands] and S. saprophyticus [n=9; 66.7% (n=6) from mushrooms and 33.3% (n=3) from hands]. Six isolates that were characterised as multidrug resistant were isolated from hands of handlers. Most (83.9%; n=47) of the 56 isolates were resistant to penicillin [53.2% (n=25) from mushrooms and 46.8% (n=22) from hands] and 14.3% (n=8) were resistant to cephalosporin classes [25% (n=2) from mushrooms and 75% (n=6) from hands], both of which are used to treat staphylococcal infections. Antibiotic resistance genes blaZ [25.0% (n=14) of all isolates of which 71.4% (n=10) were from hands and 28.57% (n=4) from mushrooms], tetL and tetK [both 1.8% (n=1) from hands], mecA [5.4% (n=3) from hands] and ermA [1.8% (n=1) from mushrooms] were detected from the 56 isolates. Only two (25.0%) of the eight methicillin-resistant staphylococci harboured the mecA gene, while only 11 (23%) of the 47 penicillin-resistant isolates harboured the blaZ gene [36.4% (n=4) from mushrooms and 63.6% (n=7) from hands]. Our results demonstrate that food handlers and harvested and packed ready-to-eat mushrooms could be a source of diverse Staphylococcus spp. that exhibit antimicrobial resistance. Clinically relevant S. aureus was only detected on one handler’s hand; however, the isolate was not multidrug resistant. The presence of diverse Staphylococcus spp. on mushrooms and the hands of  handlers is a potential public health concern due to their potential to cause opportunistic infections.Significance:

This study is the first to describe the antibiotic resistance profiles and antibiotic gene presence of Staphylococcus spp. isolated from fresh mushrooms and hands of pickers and packers. Mushrooms and handlers in this study were demonstrated to be possible routes of transmission of Staphylococcus spp. that are antibiotic resistant and which harbour antibiotic resistance genes, presenting a possible public health hazard.

Food insecurity, obesity and hypertension remain major public health issues related to nutrition in South Africa. The purpose of this study was to determine household food security and the health risk of the adult population in the Limpopo Province using cross-sectional designs. A stratified random sampling method was used to recruit adults aged 18 to 65 years in the Limpopo Province of South Africa. Data were collected using a validated, structured questionnaire. All data were analysed using SPSS version 25.0. The study included 640 participants with an average age of 36.2±17.6 years and a household size of five persons; 74.5% of participants fell in the low monthly income bracket (≤ZAR3000). The mean dietary diversity score was 3.99 (CI: 2.79–5.19). The prevalence of food insecurity was 31.3%, obesity 35.2% and hypertension 32.3%. Being a woman, older and married significantly positively influenced obesity and hypertension. Also, a healthy eating lifestyle such as high dietary diversity was found to positively influence obesity status, while daily eating of fruit and vegetables positively significantly influenced the hypertension status of participants (p<0.05). Food insecurity, obesity and hypertension rates remain high among adults in the Limpopo Province of South Africa with consumption of a diet low in dietary variety. Aged and married women were more likely to be obese and hypertensive, while daily fruit and vegetable intake were found to be a protective factor. Educational and nutritional intervention should be designed and geared towards promoting fruit and vegetable intake in the community.Significance:

Households had a diet low in dietary variety, with dietary diversity revealed as a determinant of health risk.
Dietary diversity is inversely correlated with household food security.
The findings also identified household determinants of obesity and hypertension, which are major public health issues in South Africa.
Determination of alcohols in hand sanitisers: Are off-the-shelf hand sanitisers what they claim to be?
Authors: Yusuf Abdullahi A.
Published: November 2021

Transmission of SARS-CoV-2 – the causative agent of COVID-19 – can be prevented through non-pharmaceutical interventions such as observing proper hand hygiene using alcohol-based hand rubs/sanitisers (ABHRs) as recommended by the WHO and local health authorities. However, this recommendation has led to high demand for ABHRs and proliferation of sub-standard products, which do not contain the recommended amount of alcohol. Fifty products of different origins and formulations obtained off-the-shelf and in public places in and around Pretoria (South Africa) were analysed for their alcohol content using gas chromatography. Ethanol was the most common alcohol used in the products, followed by isopropanol. Only 21 (42%) of the products analysed contained at least 70% alcohol; of these only 14 (28%) met the WHO recommended 80±5% alcohol content to have a virucidal effect on SARS-CoV-2. Of the 41 commercial off-the-shelf products analysed, 27 (66%) contained less than 70% alcohol in comparison to 13% of homemade products. Only 18% of gel products contained 70% alcohol, compared with 47% for liquid-based products. Most of the products did not contain the appropriate or correct declaration as recommended by the South African National Standards (SANS 289 and 490). The proliferation of substandard ABHRs is of great public health concern and calls for stricter regulations and enforcement in order to protect consumers, their rights and well-being during and post the COVID-19 pandemic period. However, in the interim, formulation of ABHRs using the WHO guidelines should be mandatory, as such formulations, when made correctly, do have the required virucidal effect against SARS-CoV-2.Significance:

Commercial, off-the-shelf and public hand sanitisers were analysed to determine whether they contained enough alcohol to be efficacious virucides as recommended by the WHO.
The majority of the products analysed were substandard, did not contain the recommended amount of alcohols and were not labelled correctly according to local and international standards.
Homemade products conformed to a greater degree to the WHO standards for alcohol-based hand sanitisers. It is evident from these results that there is a need to monitor the manufacture of off-the-shelf products to ensure compliance and to assure consumers that products offer the required protection against SARS-CoV-2.

Beton merupakan suatu material yang banyak digunakan dalam dunia konstruksi. Namun, setiap produksi beton menimbulkan dampak buruk pada pemanasan global. Semen sebagai bahan pengikat beton dapat menyumbang emisi CO2 sebanyak 8% dalam setiap produksinya. Proses pengecoran pada beton juga dapat menghasilkan polusi suara akibat penggunaan alat vibrator. Para peneliti terus berupaya menghasilkan beton yang lebih ramah lingkungan. Self Compacting Geopolymer Concrete (SCGC) merupakan kombinasi baru antara beton geopolimer dan Self Compacting Concrete (SCC) yang masih terus diteliti dan dikembangkan hingga saat ini. SCGC merupakan beton ramah lingkungan karena tidak menggunakan semen portland sebagai bahan pengikatnya. Penggunaan beton SCGC tidak memerlukan vibrator karena memiliki sifat flowability yang baik. Penelitian ini menggunakan bahan pengikat berupa material pozzolan yang mengandung senyawa kimia berupa SiO2 dan Al2O3. Tahapan penelitian ini dilakukan dengan mencari metode curing dan mix design optimal dalam penyusunan SCGC. Pengujian XRF perlu dilakukan dalam penelitian ini untuk mengetahui kandungan senyawa kimia pada fly ash Tjiwi Kimia. Beberapa pengujian beton segar SCGC diperoleh hasil berupa slump flow 690 mm, T50 2,4 detik, v-funnel 8,35 mm, dan rasio l-box 0,84. Sifat mekanik beton diuji berdasarkan kuat tekan, kuat tarik belah, dan kuat lentur dengan hasil rata-rata sebesar 27,05 MPa, 6,32 MPa, 1,91 MPa.

Background: Aspirin is amongst the most widely used drugs and has many adverse effects on gastric mucosa. Anti-inflammatory properties of Acacia catechu have been established already. Objective was to evaluate the histopathological changes induced by aspirin in the stomach of albino rats and to assess the protective effect of different doses of Acacia catechu.Methods: Experimental study Postgraduate Medical Institute, Lahore for 21 days. Forty-eight adult albino rats, both males and female, were divided into four groups A, B, C and D randomly; each comprising of 12 rats. Group A was control, group B was given aspirin 100 mg/kg and group C and D were given aspirin 100 mg/kg along with Acacia catechu 250 mg/kg and 500 mg/kg respectively by oral route. The rats from individual group were sacrificed on 3rd day, 7th day and 14th day and stomachs were examined under light microscope to observe the inflammatory cells infiltration.Results: Gross and microscopic findings on days 3, 7 and 14 were similar. Control groups A1, A2 and A3 showed normal healthy gastric mucosa and the least number of inflammatory cells. In group B, aspirin produced ulcerations and linear breaks; with highest inflammatory infiltrates. On microscopic examination, numerous inflammatory cells were noted. Group C and D rats had minimum ulcer index and fewer inflammatory cells.Conclusions: Acacia catechu has protective role against gastric injury by inhibiting inflammation.

Background: The aim of this study was to identify common ocular manifestations in children with developmental delay in an eye hospital of northern part of Bangladesh.Methods: It was a retrospective medical record review of children with developmental delay who attended the pediatric ophthalmology department in an eye hospital from January 2019 to December 2019. Data were collected for their age, gender, past medical history, ophthalmic examination findings and systemic problems. Ophthalmic examination included examination of lid and adnexa, anterior and posterior segment examination and assessment of squint and refraction.Results: Medical records of 102 with developmental delay were identified and studied (59 boys and 43 girls, mean age 1.57 years, 53.9% aged <1 year). Of these children, 44 (43.1%) were referred by the pediatricians. The most common past medical histories were perinatal asphyxia (42.2%), history of convulsion (30.4%), neonatal seizures (9.8%) and history of speech delay (1%). On ophthalmic examination, 30 (29.5%) had poor vision, 20 (19.6%) had refractive error, 23 (22.5%) had Strabismus and 11 (10.8%) had nystagmus. Optic atrophy was also observed among 11 children (10.8%).Conclusions: Ocular manifestations are commonly seen in children with developmental delay which can be cause of severe visual impairment and overall disability in later life. Hence an early ophthalmologic screening and intervention in these children by developing good referral network between ophthalmologist and pediatricians can help to substantially improve the developmental and academic achievement.

Background: The World Health Organization (WHO) estimates that about 804,000 persons die annually from suicide. Suicidal ideation in adults results from a complex interplay of biological, psychological, and social factors.Methods: This was a descriptive cross-sectional study among 450 adults in Benin City, Edo State, Nigeria. A multistage sampling technique was used to select respondents. Data were obtained using pretested structured self-administered questionnaires which were adopted from the adult suicidal ideation questionnaire. Data analysis was by IBM statistical package for the social sciences (SPSS) version 22.0, and the level of significance was set at p<0.05.Results: A total of 450 respondents participated in this study, mean age±standard deviation (SD)=23.7±5.3. One hundred and forty-six (66.4%) respondents had good knowledge of suicidal ideation and 207 (94.1%) had a positive attitude towards suicidal ideation. One-tenth of respondents were at risk of committing suicide.Conclusions: One-tenth of the respondents were at risk of committing suicide. The government and medical personnel need to put in concerted efforts to ensure that suicidal ideation among adults is promptly addressed.

Background: An experimental study was conducted to evaluate the effectiveness of planned teaching programme on knowledge regarding polycystic ovarian disease (PCOD) among adolescent girls.Methods: The research design adopted for the study was one group pre – test post – test design and approach was educative and evaluative approach. This study was undertaken in village of Sursinghdhar, New Tehri, Uttarakhand, India. The data were collected through the questionnaire method with sample size 60 adolescent girls.Results: Findings related to the assessment of pre-test knowledge regarding PCOD depicted that 48.4% of the respondents had average knowledge while 43.3% had poor knowledge. Only 8.3% had good knowledge regarding PCOD. The pretest mean and Sd was 10.1±4.0. Post-test knowledge regarding PCOD depicted that 81.7% of respondents had good knowledge whereas 16.7% and 1.6% reported average and poor knowledge. The post test mean and SD was 19.0±2.8. Effectiveness of PTP on knowledge regarding PCOD among adolescent girls was calculated by paired t- test; and value was 24.1 with p value of 0.001 (S) at ≤0.05 level of significance. It was highly significant. Chi square test revealed that there was significant association between pre-test knowledge score with age (p value 0.02) and previous knowledge socio-demographic variable p value 0.05 at ≤0.05 level of significanceConclusions: The overall findings of the study clearly shows that the pretest knowledge was very less related to PCOD and there is the statistically enhancement in post-test knowledge after PTP. It reveals that, if the adolescent girls are provided regular awareness programme on PCOD will definitely brief up their knowledge, which in turn to improve the total quality of one’s reproductive health.

Background: Immunization is a key to child survival. Immunization is one of the foremost effective and cost-effective ways to protect children’s lives and futures. Despite clear evidence that vaccines save lives and control disease, millions of young children around the world are missing out, putting them and their communities at risk of disease and deadly outbreaks. This is unacceptable in the present era, where affordable, lifesaving vaccines exist. This study aims to study factors influencing timeliness of vaccination and to assess reasons for delay in immunization.Methods: A Cross-sectional study was conducted among mother/caretaker and children (under five years age) attending immunoprophylaxis clinic at a tertiary health care hospital in central India. Total 171 study subjects accompanied by mother/caretaker are included in the study. Analysis was done using SPSS version 20.0. Chi square test and Fischer’s exact test were used to find the association between characteristics of study subjects and obstetric variables with delayed vaccination.Results: Delayed Vaccination is present in 119 (69.6%) of study subjects. Among the reasons for delayed vaccination, majority were parent related reasons which was present among 84 (70.5%) of study subjects. The association of higher birth order with delayed vaccination was found to be statistically significant.Conclusions: The overall delayed vaccination was present in 69.6% of children and high birth order (3 or more) has a significant association with delayed immunization.

Background: According to national family health survey-5 (NFHS-5), in urban Karnataka, the total unmet need was 7.3. An important concept to describe effectiveness of family planning program is unmet need for family planning. Most married women want to limit childbirth and space deliveries but are unable to use contraceptives for varying reasons leading to unmet need. To assess unmet need of family planning and its associated factors among married women in reproductive age group in Mysuru.Methods: A community based cross-sectional study was done from November 2020-January 2021 among married women in reproductive age group (18-49 years) in urban Mysuru. Sample size calculated was 162. The samples were selected by systematic random sampling and interviewed using a pre-tested semi- structured questionnaire. Data was analysed using SPSS version 23 (licensed to JSS AHER).Results: The overall unmet need was 29.01%, among this 17.3% was for spacing and 11.71% for limiting. Out of 162 females studied, around 131 had knowledge about at least one contraceptive method. Unmet need was higher in unemployed women belonging to the lower socio-economic group. Important reasons cited for not using contraceptives were family opposition, fear of side effects, negligent attitude of the women and lack of knowledge about family planning.Conclusions: Unmet need of family planning in the study area was comparatively high, therefore, routine family planning counselling, health education, and health awareness programs need to be strengthened.
