Background:

Laparoscopic definitive surgery for choledochal cyst (CC) in infants requires advanced skills because of their small size. If patients with a prenatal diagnosis of CC have any biliary symptoms, they need semi-emergency definitive surgery. This study aimed to estimate whether laparoscopic definitive surgery for CC can be performed safely and effectively in infants, especially when emergency surgery is required.

Patients and Methods:

From January 2006 to December 2019, 21 patients under 1 year of age underwent laparoscopically or open definitive surgery, and 16 patients aged 3–5 years underwent laparoscopic surgery for CC at our institution. In cases of prenatal diagnosis, elective surgery (EL) was performed at about 6 months of age for patients with no biliary symptoms; the semi-emergency surgery (EM) was performed when patients had any biliary symptoms. Surgical outcomes were retrospectively compared between the Lap <1 y and Op <1 y groups and between the Lap <1 y and Lap 3–5 y groups. In addition, the surgical outcomes of those who underwent EM were also evaluated.

Results:

Operative time was significantly longer, and blood loss was significantly lower in the Lap <1 y group than in the Op <1 y group. All surgical outcomes were similar between the Lap <1 y and Lap 3–5 y groups and between the EM and EL groups.

Conclusion:

Laparoscopic definitive surgery for CC in infants under 1 year of age is safe and feasible. Even semi-emergency laparoscopic surgery can be performed safely and effectively in small infants.

During the corona virus disease 19 (COVID-19) pandemic, most of the medical schools across the world has started to transfer the curriculum from face-to-face to online delivery using various virtual platforms for undergraduate teaching without any uniformity. It is imperative to understand the students' outlook about the current online teaching in order to make it more effective. This study was planned to gain an insight into the medical students' perspective toward online teaching–learning program and the challenges faced by them toward the same.

Materials and Methods:

It was a cross-sectional descriptive study conducted for 3 months at a medical college in Chengalpet district, Tamil Nadu, among 351 medical students across all professional years. The Google form platform was used to administer a semi-structured questionnaire to all the participants to obtain information related to various parameters of online teaching-learning. The statistical analysis was done using frequency and percentages.

Results:

A total of 351 students participated in this study, including 134 males and 217 females. Almost 318 (90.6%) perceived that online classes were able to cover academic portion amidst COVID-19 pandemic. The most common challenges found were network related issues, lack of practical sessions, including dissection and lack of exposure to clinical cases cited by 181 (90%), 77 (38.3%) and 72 (35.8%) participants, respectively.

Conclusions:

The study reveals the perspectives of medical students on online teaching–learning sessions and identifies important challenges pertaining to it. However, the positive overall experience by the students provides confidence to the medical education fraternity in the entire process of online teaching and learning amidst the COVID-19 pandemic.

Published: June 2022

Background:

Growing life expectancy is challenging the quality of health care for elderly. Information regarding health-related quality of life (QOL) may help policy makers to design need-based health programs for this population.

Objectives:

The objective of the study was to estimate health-related QOL of the geriatric population living in rural areas of West Tripura district and to compare it between ethnic and nonethnic populations in respect to important domains.

Materials and Methods:

This community-based cross-sectional study was conducted during February 1, 2019–March 31, 2020 among 225 geriatric subjects of rural West Tripura district chosen by multistage sampling. The World Health Organization's QOL–BREF scale was used for data collection.

Results:

Among the study population, 46.2% had overall good health-related QOL. About 52.9% had good QOL in the environment, and 37.3% had good QOL in social relationship domains. Marginally higher proportion of the subjects from ethnic origin had better QOL than the nonethnic, but it was not significant. A higher proportion of the Muslim subjects had better QOL than the rest, but it was also not significant. Bivariate analysis showed significant associations of QOL with age, sex, literacy, financial condition, socioeconomic status, and type of family. Multivariate analysis identified male sex, younger age, and living with spouse as significant predictors of good QOL.

Conclusion:

Overall health-related QOL of the geriatric people living in rural areas of West Tripura district is poor, but younger male subjects of ethnic origin and living with spouse may enjoy relatively better QOL.

Authors: Jain Shivi , Shukla Ram Chandra , Jain Madhu , Singh Usha , Singh Tej Bali
Published: June 2022

Background:

Antral follicle count (AFC) and anti-Mullerian hormone (AMH) have been used as indicators of ovarian reserve in infertile women. There still exists a debate about the association between the two parameters.

Objective:

The objective of the study was to find out the relationship between AFC and AMH in infertile women.

Methods:

This was a prospective, hospital-based, cross-sectional study, in which 1083 infertile women (aged 20–40 years) with primary infertility were included. They were divided into four age groups, i.e., Group I (20–24 years), Group II (25–29 years), Group III (30–34 years), and Group IV (35–40 years). AMH and AFC were measured on 3rd day of menstrual cycle. Pearson correlation and linear regression analysis were done to find out the relationship between age, AFC, and AMH. Statistical analysis was done using IBM SPSS Statistics for Windows, version 20 (IBM Corp., Armonk, N.Y., USA). A P < 0.05 was considered statistically significant.

Results:

There was modest negative correlation of AFC with age (r = −0.476,P< 0.001). AMH showed strong negative correlation with age (r = −0.844,P< 0.001) and modest positive correlation with AFC (r = 0.400,P< 0.001). For separate age groups also, statistically significant correlations (P < 0.05–P < 0.001) were noted between age, AFC, and AMH. Age explained 22.7% variation in AFC and 71.2% variation in AMH.

Conclusion:

There was a significant correlation between AMH and AFC in infertile women. AFC showed a continuous decline with increasing age. However, AMH increased with age till third decade of life and showed negative correlation with AFC. Thereafter, AMH started decreasing with age and showed positive correlation with AFC.

Published: June 2022

COVID -19 since its inception from the month of December 2019 has been associated with myriads of systemic complication apart from the respiratory failure, with Guillain-Barre syndrome (GBS) being one of the prominent neurological complication. More than 220 patients with GBS have been reported thus far. We wish to share 3 cases of GBS associated with COVID 19 admitted in our institute. GBS is one of the most common causes of acute, acquired weakness and is often provoked by a preceding infection, which triggers an immune response, cross-reacts with shared epitopes on peripheral nerve (molecular mimicry). Interestingly one of the cases developed limb weakness concurrently with the respiratory symptoms, probably during the viremic phase; the other 2 cases few weeks after recovering from COVID 19. So, is there a specific association with covid 19 and GBS? If associated, is it Para infectious or Post infectious? Further studies are needed to unravel its association with COVID 19.
Risk factors associated with complicated alcohol withdrawal syndrome
Authors: Banyal Navdeep , Dhillon Harpreet Singh , Sasidharan Shibu
Published: June 2022

Background:

Alcohol withdrawal syndrome (AWS) is a frequent presentation in patients with alcohol dependence syndrome. Complicated alcohol withdrawal state (i.e., delirium and/or convulsions) is the most severe form with significant morbidity and mortality if left untreated. Therefore, it is imperative to identify the risk factors associated with complicated AWS for early diagnosis and swift management.

Materials and Methods:

This study utilized a cross sectional design in a tertiary care center on 60 patients to identify the risk factors associated with complicated alcohol withdrawal. The data collected were subsequently subjected to statistical analysis with appropriate tests (Pearson Chi-square test, t-test).

Results:

Out of the 60 patients, 30 developed complicated AWS. Amongst the demographic variables, patients with education <10th standard, unemployment and history of delirium tremens were found to be significant predictors of complicated AWS. Patients with complicated AWS consumed higher mean ± standard deviation (19.33 ± 1.77 vs. 11.87 ± 1.17) units of alcohol per day (P < 0.001). The duration of alcohol withdrawal lasted for 7.13 ± 4.17 days in complicated AWS compared to 5.23 ± 2.70 days in uncomplicated (P = 0.041). Tacycardia (P = 0.001), respiratory rate (P = 0.001), low platelet count (P < 0.001) and higher Erythrocyte sedimentaion rate (P < 0.001) were also found to be significant predictors of complicated AWS. Serum gamma-glutamyl transferase GGT values were higher in complicated AWS but the difference was not statistically significant.

Conclusion:

This study found lower education, unemployment, history of delirium tremens, higher units of alcohol consumed per day, tacycardia, higher respiratory rate, lower platelet count and higher erythrocyte sedimentaion rate as significant predictors of complicated AWS.

Published: June 2022

The study examined market participation behaviour among urban okra producers in Ojo Local Government Area, Lagos State, Nigeria. A two-stage sampling procedure was adopted in selecting 120 vegetable farmers during the dry season extending from November to March 2018/2019. Data on socioeconomic and demographic characteristics, farm-specific factors, and marketing and production output activities were collected using a well-structured questionnaire. Data collected were analysed using descriptive statistics (such as mean, standard deviation and percentage) and a Tobit regression model. Most of the urban farmers were young and educated and in their economic active age. The mean market share of okra marketed by the respondents was 7,662.17kg (representing 89.8% of okra produced). Sex, primary occupation, per capita land size, cost of seed, price of okra per unit, distance to nearest market and cost of labour significantly determined market participation (p<0.05). The study recommends policies that facilitate access to production resources like land, seed or planting material and farm labour at lower costs. The land policy that makes access to marginal land in an urban area available for agriculture should be as a form of empowerment to the vulnerable in society. Also, upgrading farm-to-market roads to reduce transportation costs to distant urban markets which offer better prices and encourage farmers to produce more marketable produce.
Student housing investment strategies through location and building services. A study of privately-owned student housing around university campuses in Northern Ghana
Authors: Aziabah Samson Akanvose , Miller Appau Williams , Attakora-Amaniampong Elvis
Published: June 2022

The study assesses the investment strategies private investors employ in student housing to remain viable by attracting students to the hostels with minimum impact of location on such decisions of students. The study used a mixed-methods approach involving surveys and interviews. The Hedonic Price Model through Multiple regression and ANOVA were used to analyse quantitative data, while qualitative data were analysed using themes. The study found a gradual rise in student housing rent with increasing distance from university campuses. As a strategy, investors in student housing distant from university campuses offer special building services over and above those hostels near campuses. It allows distant hostels to stay competitive in the student housing market. In addition, the paper highlights student's' preferences such as internet services, private lavatories and security, which investors should consider in the provision of student housing to enhance occupancy rate and eventually increase returns. The study also reiterates the need for specificity in using the Hedonic Price Model in housing research.

Published: June 2022

Malaria is a vector-borne disease transmitted by Anopheles mosquitoes, in particular Anopheles gambiae s.l. To identify malaria vectors and establish a link between the presence of malaria vectors and malaria prevalence, a study was carried out in 7 localities of the Kara region: Lassa-Bas, Sarakawa, and Kpindi in the Kozah prefecture and Siou, Défalé, Ténéga and Broukou in the Doufelgou prefecture. Two malaria indicators were evaluated including the prevalence rate as well as consultation rate among children aged under 5 and pregnant women in the above-mentioned areas. Additionally, adult mosquitoes were collected using Human Landing Catch and Spray Catch techniques in the following localities: Lassa-Bas, Sarakawa, Siou, and Ténéga. Malaria prevalence rate was globally > 70%, the consultation rate was also > 50% among children under 5 years in the two prefectures. In pregnant women, the prevalence was > 60% while the consultation rate was 45%. A total of 592 mosquitoes were collected, divided into 3 genera: Anopheles, 521 (88%); Culex, 54 (9%); and Aedes, 17 (3%). Of the overall Anopheles mosquitoes collected, Anopheles gambiae s.l. represented 100% in all the localities (Lassa-Bas, 140; Sarakawa, 62; Ténéga, 303; and Siou, 16), followed by Aedes aegypti, Aedes sp, and Culex spp. The high rate of malaria prevalence could be potentially linked to the abundance of Anopheles mosquitoes.
Comparaison de l’effet de deux champignons mycorhiziens arbusculaires sur la croissance et la productivité du sésame (Sesamum indicum L.) au Burkina Faso
Authors: Zoungrana Adama , Zi Yacouba , Sanou Abdoul K. , Savadogo Paul W.
Published: June 2022

L’agriculture conventionnelle caractérisée par une forte utilisation de pesticides et d’engrais chimiques entraine de nombreuses répercussions délétères sur la santé humaine et sur l’environnement notamment la dégradation de la fertilité des sols. Pour atténuer ces effets, l’agriculture biologique basée sur l’utilisation des champignons mycorhiziens arbusculaires pourrait être un modèle alternatif. L’effet de l’inoculation mycorhizienne avec Glomus aggregatum et Rhizophagus irregularis sur la productivité du sésame a été étudié. Les résultats de l’inoculation du sésame avec ces deux souches ont été comparés au témoin non inoculé et au traitement fertilisé au compost dans un dispositif en bloc de Fisher. Les résultats ont montré que l’intensité de mycorhization des plantes de sésame est très faible tout au long du cycle végétatif (de 8,65% à 22,72%). L’inoculation du sésame avec Glomus aggregatum a également eu un effet significatif sur le nombre de capsules (plus de 54 capsules/plante), la biomasse totale et le rendement graine (362,27 Kg ha-1) comparativement au témoin (315,51 Kg ha-1). L’effet de Rhizophagus irregularis en provenance du Sénégal n’a pas été significatif sur tous les paramètres morphologiques du sésame contrairement au témoin naturellement mycorhizé. Les champignons mycorhiziens arbusculaires indigènes présents dans les agroécosystèmes du Burkina Faso induisent donc plus d’effet sur le sésame que la souche de Rhizophagus irregularis provenant du Sénégal.

Published: June 2022

Le climat est l’un des facteurs les plus importants de la production des cultures. Il influence tant positivement que négativement l’ensemble des activités agricoles et a une action marquée sur le rendement des cultures. Les changements présents dans les éléments constituant le climat permettent de comprendre le niveau de productivité actuel, de concevoir et/ou modifier les pratiques des producteurs. L’objectif de cette étude était de déterminer l’effectivité d’un changement du climat et d’identifier les risques possibles de ces changements climatiques sur la culture du Café Robusta. La série de données de 44 ans (1974 -2017) pour les précipitations et le nombre de jours de pluie, celle de 38 ans (1980 - 2017) pour les températures moyennes et celle de 37 ans (1981 -2017) pour l’humidité relative moyenne, ont été obtenues à la station météorologique de Nkongsamba. Ces séries ont été ensuite découpées en deux périodes de 30 ans chacune. La détection des changements dans les séries s’est faite par le logiciel changepoint.np de R et la méthode PELT, tandis que la comparaison des deux périodes de 30 ans chacune s’est faite à l’aide du test de Student et celui de Wilcoxon. Les résultats ont montré que les changements climatiques sont réels dans le bassin de production du Moungo. Ils sont caractérisés par l’augmentation des températures moyennes de 0,9°C, couplée à une réduction de 20 jours de pluie et la baisse de 1,3% de l’humidité relative. Par ailleurs une réduction de 10 jours de pluies entre les deux périodes de 30 ans a été observée. Elle est couplée à une augmentation des températures moyennes de 0,8°C. Les risques causés par ces changements sur la culture du café robusta sont légers. Toutefois ces changements concourent aux conditions favorables de développement du principal ravageur du caféier Hypothenemus hampei. L’association du café avec des espèces agroforestières, ainsi qu’une protection phytosanitaire adéquate, peut réduire la pression du ravageur et augmenter les rendements du café.

Cette étude avait pour but de comprendre le fonctionnement hydrogéochimique des eaux souterraines du département de Man situé à l’Ouest de la Côte d’Ivoire. Elle a fait appel aux méthodes de statistique descriptive, hydrochimique (diagramme de Piper) et à l’analyse en Composantes Principales (ACP) pour connaître la qualité, les faciès chimiques et les phénomènes de la minéralisation des eaux souterraines. L’échantillonnage a concerné 19 forages et les paramètres chimiques analysés sont Ca2+, Mg2+, Na+, K+, NH4+, SO42- , HCO3- , NO3-, Cl-, NO2- , Cu2+, Fe2+, PO43- et Al3. Les résultats de la statistique descriptive ont montré que les eaux avaient une température moyenne de 27,34°C en saison sèche et 28,005°C en saison pluvieuse. Les eaux étaient acides pendant les deux saisons. Les valeurs de pH étaient comprises entre 5,58 et 7,74 avec une moyenne de 6,673±0,541 en saison sèche et entre 5,25 et 7,11 avec une moyenne de 6,223±0,441 en saison pluvieuse. Elles étaient peu minéralisées, avec des moyennes de conductivité électrique de 219,51 μS/cm en saison sèche et 206,50 μS/cm en saison pluvieuse. Ces eaux présentaient un faciès bicarbonaté calcique et magnésien majoritaire (Ca-Mg- HCO3), un faciès chloruré calcique et magnésien (Ca-Mg-Cl) au cours des deux saisons et un faciès bicarbonaté sodique et potassique en saison pluvieuse (Na-K-HCO3). Les principaux phénomènes à l’origine de la minéralisation des eaux étaient la minéralisation-temps de séjour, l’apport superficiel et la dégradation anthropique de la qualité des eaux et la pollution organique. Ces résultats constituent une base de données dans la gestion des eaux souterraines de la région.

Effect of anthropogenicity on the temporal diversity and abundance of macro-invertebrates in Calabar River, Okomita, Cross River State, Nigeria
Authors: Okorafor K. A. , Ugwumba A. A. A.
Published: June 2022

The influence of anthropogenicity on the abundance and diversity of macro-invertebrates was investigated in Calabar River, Okomita, Cross River State for a period of 24 months (August, 2014-September, 2016) in six sampling stations. Bank root macro-invertebrates were collected by kick sampling while substrata macro-invertebrate samples were collected with a van-Veen grab. Seasonal variations in the values of the macro-invertebrates abundance were determined by pooling together the values for the wet and dry seasons. The difference in values in the six stations in each season was tested for significant difference (p < 0.05) while the pooled differences in the two seasons were tested using unpaired (independent) student’s t-test. Spcies diversity was estimated using the Shannon-Wiener index (H’), species richness (d) and evenness (J) of individual distribution among species. All macro-invertebrate groups had highest percentage abundance in the dry season months. Seasonal percentage abundance of insects was significantly different (p˂0.05). Higher seasonal abundance of the total macro-invertebrates was recorded in the dry season and the seasonal variation was significant (p˂0.05). Lower number of pollution intolerant species of macro-invertebrates (Sudanonautes africanus, Orectochilus orbisonorum, Dineutus discolour, Phaon iridipennis, Pila ovata, Natica flammulata and Eulima fischeri) recorded during the rainy season was an indication that the river was more perturbed during the rainy season as a result of influx of pollutants from refuse dumps, farmlands, Okomita Market, abattoir and mechanic workshop. The results of the PCA revealed that DO, hardness, alkalinity, magnesium and cadmium were the most important parameters influencing the abundance of macro-invertebrates in Calabar River, Okomita. Intermediate values and values less than one of Shannon-Weiner diversity index were observed, indicating that Calabar River, Okomita is moving from moderately polluted state to severely polluted condition.
Implications of ecological parameters on earthworm diversity and abundance in southwestern Nigeria
Authors: Aladesida A.A. , Owa S.O.
Published: June 2022

A survey on the diversity and abundance of earthworms in southwestern Nigeria was carried out. Earthworm and soil samples were collected from thirty different locations within the sub-region. Earthworms were identified and soil samples were analysed for mineral and metal loads, using standard procedures. Taxonomic analysis of collected earthworm samples revealed 24 species belonging to eight families namely Moniligastridae, Megascolecidae, Acanthodrilidae, Octochaetidae, Ocnerodrilidae, Eudrilidae and Almidae. These include some genera and species that are reported for the first time from Nigeria. Analysis of earthworm biomass showed that Libyodrilus violaceus had the highest biomass (104.4g/m2) while Hyperiodrilus africanus had the highest density (160 worms/m2). Earthworm biomass correlated negatively but significantly with pH (p<0.01). Analysis of earthworm abundance in relation to soil types indicates that E. eugeniae was present in all seven soil types studied, while only Alma millsoni and H. lagosensis can be used as indicators of ferruginous tropical soils and red-yellow ferralsols. Earthworms from this study revealed affinity for various combinations of sand and loam soils. The present results revealed a decline in earthworm abundance when compared with previous works. This work revealed the need to harness the habitat factors, which support earthworm abundance for use in both earthworm and soil conservation efforts.
Amphibian diversity in urban and peri-urban landscapes of Benin City, a Southern Nigerian City in the rainforest biotope

Published: June 2022

Benin City, the capital of Edo State of Nigeria has undergone tremendous changes in recent times, especially with the aggressive rate of urbanisation in the last two decades. This has invariably resulted in habitat loss and fragmentation for the amphibian community of the city and its environs. In order to determine the effect of urbanization on the amphibian diversity of the area, a survey was undertaken between July 2009 and July 2010 using Visual and Acoustic Encounter Survey method. Higher species diversity and richness was observed from the peri-urban compared to the urban areas. However, the abundance of amphibian in the urban zone was significantly higher than that of the peri-urban zone (p<0.05). Hyperolius concolor phases A and C, H. sylvaticus, Afrixalus nigeriensis and A. vittiger were restricted to the peri-urban area while Ptychadena pumilio and Sclerophrys maculata occurred more in the urban areas. The most dominant species was S. maculata (26.6%) while the least dominant species was A. vittiger (0.22%). Peri-urban areas contributed 53% while the urban zone contributed 47% to total abundance. More tree frogs were collected from the peri-urban than the urban sites, which could be due to the reduced vegetation cover in the latter. However, the paucity of tree frogs in the urban zone did not have any significant impact on the taxa differences between the two zones. The abundance of P. pumilio and P. mascareniensis, which are typical savanna frogs is an indication of the degraded nature of the study area. The low records of A. poecilonotus, A. vittiger and H. concolor phase A and the complete absence of forest-dependent species could be due to their inability to tolerate human influence on the environment. There is need for balance in the use of land resources for urbanization and amphibian conservation.

The article presents the results of industrial testing of processes for obtaining high-purity uranium compounds, including extraction, concentration, and purification of uranium from a mixture of nitric and phosphoric acids, solid-phase stripping, and reduction of U(VI) to U(IV). It is shown that the combination of three different extraction lines for the concentration and purification of uranium from accompanying valuable elements and radioactive isotopes makes it possible to obtain a natural uranium concentrate with a low content of impurities, which determine the economics of uranium hexafluoride production. The processes of drying and roasting of crystals of ammonium uranyl tricarbonate after solid-phase re-extraction in an atmosphere of reducing gases of ammonia and hydrogen make it possible to obtain uranium dioxide suitable for fluorination to obtain tetra and uranium hexafluoride.

Published: June 2022

Taxonomic positions and phylogenetic relations of Hebeloma species have not yet been figured out molecularly in Turkey. Most species of the genus are mainly poisonous and a few of which are edible. Hebeloma crustuliniforme and H. sinapizans are two important species that contain deadly toxins so only morphological characters may not be enough for reliable identification. The DNA sequence of the nuclear ribosomal Internal Transcribed spacer (nrITS) region is used in addition to morphological characters in the present study. Phylogenetic analysis is conducted on the sequence dataset by using the Maximum Likelihood (ML) principle to see the taxonomic placement of two poisonous species. Studying morphological traits and molecular markers together is very useful to distinguish these two poisonous species from close relatives. The first sequence data of these species were added to the literature on behalf of our country with this study.

Neonatal mortality is an index for newborn care and maternal health care. It is a useful indicator for obstetrical and neonatal healthcare services quality and availability. It is influenced by environmental, economic and social factors. Therefore, it is a measure of socio-economic status and health system. The study was a cross sectional one. It was conducted at Al Resafa side in Baghdad city. The requested data were reviewed from medical records (sex, cause of death, etc.). Chi-square was used to show the impact of dependent variables (death causes) on the independent variables (sex, and type of neonatal death). P value < 0.05 was considered statistically significant. The results showed number of neonatal deaths per 1000 livebirths ranged from 19.30-19.08 per 1000 livebirths between 2015 - 2019 respectively. Males had the highest neonatal deaths through studied years (54.8%, 54.5%, 56.4%, 57.2%, and 59 respectively). Prematurity (487, 32.1%), and respiratory distress syndrome (387, 25.5%) were significantly the common causes of early neonatal deaths. Sepsis (216, 30.1%), and respiratory distress syndrome (149, 20.8%) were significantly the main late neonatal deaths causes (kh 2= 429.582, p value = 0.001). Both males and females mainly died from prematurity (340, 285; 27%, 29.2% respectively). The distribution of causes of neonatal death were significantly varied between sexes (kh2= 20.782, p value= 0.001). In conclusions, neonatal mortality rate is high in the studied period. Two thirds of neonatal death occurred early.
