Chronicles of A.I. Pospelov Moscow Dermatovenerology and Cosmetology Society (MDCS was founded on October 4, 1891) Bulletin of the MSDC № 1140
Authors: Yakovlev Alexey B. , Maximov Ivan S.
Published: November 2022

On November 17, 2020, the 1140th meeting was held in on-line format.
In total there were 92 participants. Five people were accepted as members of the MDCS.
The clinical agenda of the meeting considered cases of subacute (disseminated) cutaneous lupus erythematosus and reactions to tattooing in the form of pseudolymphoma of the skin. The interest of observing disseminated lupus erythematosus was in the difficulties of diagnosis due to its combination with Sjogrens syndrome, a long history of the disease, the severity of the skin process and the peculiarities of the selection of adequate drug therapy. Analysis of the case of pseudolymphoma development as a reaction to a tattoo in a patient with atopic dermatitis helped to approach a more accurate understanding of the clinical and pathogenetic aspects of this process: probably, the pathophysiological reaction is based on a reaction to a foreign body, which makes this disease related to sarcoidosis.
The scientific agenda of the meeting reported on the advantages of using photodynamic therapy for skin T-cell lymphomas, such as good cosmetic results; non-invasive nature of the procedure; selectivity; low risk of toxicity; low photosensitivity; low carcinogenic potential. In another report ― on the use of signaling pathway blockers in the treatment of psoriasis ― the results of an open uncontrolled prospective clinical study of the effectiveness of apremilast in the treatment of moderate and severe psoriasis were presented.

Published: November 2022

El artículo presenta los resultados de la investigación referida al cumplimiento de la responsabilidad social (RS) en la investigación científica (IC) en el país. Asume el paradigma Interpretativo, enfoque Cualitativo, diseño Hermenéutico. La muestra estuvo conformada por cinco estudiantes de Doctorado en una universidad privada de Lima, todos con grado de Magíster e involucrados en la IC. La técnica empleada fue la entrevista y el instrumento una guía de entrevista semi estructurada. El estudio reúne criterios de credibilidad, auditabilidad, transferencia y confirmabilidad de los datos, lo que determina la cientificidad del trabajo. Los resultados determinan que la RS, en términos generales, no se cumple cabalmente en el país, debido principalmente a los intereses capitalistas de las empresas e instituciones y a los fines de lucro, que no va más allá de los intereses económicos, por lo que la población se ve desprotegida en cuanto a su bienestar. La IC en el país como generadora de conocimiento y que busca la beneficiencia de la sociedad, no se está desarrollando a la luz de las necesidades de la sociedad actual; se da un desarrollo mínimo, evidenciándose una formación académica clásica, a ello se suma que los docentes investigadores que contribuyen a la formación de los estudiantes de posgrado no tienen el reconocimiento merecido y perciben remuneraciones bajas. La RS y la IC no se vinculan de manera provechosa ni se evidencia su importancia trascendental para la sociedad. Respecto al papel de la universidad, se concluye que hay pasividad en el desarrollo de la IC con RS.

Authors: ORTÍZ PALOMINO Magaly Esperanza , FERNÁNDEZ BEDOYA Víctor Hugo
Published: November 2022

La economía colaborativa es intercambio de bienes y servicios entre miembros de una comunidad, facilitado generalmente por la tecnología. Expertos aducen que existen cuatro claros tipos de economía colaborativa: consumo colaborativo, producción colaborativa, aprendizaje colaborativo, finanzas colaborativas. Esta investigación planteó como problema de investigación ¿cuáles son las evidencias científicas de la aplicación de la economía colaborativa en Sudamérica divulgadas en las bases de datos Scielo y Redalyc en los últimos tres años?, y en específico ¿a qué grupos básicos de economía colaborativa hicieron alusión?, ¿qué giros de negocios se analizaron?, ¿bajo qué enfoque metodológico son estudiados?, y por último ¿en qué lugar de Sudamérica se encuentran los modelos de economía colaborativa estudiados? A través de una revisión sistemática, se logró dar respuesta a dichos problemas de investigación y cumplir con los objetivos de la misma. Se hallaron quince artículos científicos, de los cuales catorce hacen alusión a consumo colaborativo, uno a producción colaborativa, y ninguno a aprendizaje colaborativo ni finanzas colaborativas desde el punto de vista netamente empresarial. De igual manera, la gran mayoría de la evidencia obtenida hace alusión al negocio de hospedaje (siete casos), se abordan desde el enfoque cualitativo (diez casos), y detallan experiencias en Brasil (once casos).

El objetivo fue determinar el impacto de la pandemia y las prevalencias de los niveles de actividad física y sedentarismo en los estudiantes de Medicina de la Universidad de Guayaquil durante del confinamiento por la pandemia del COVID-19. Se consideraron a 355 estudiantes de Medicina matriculados en la Facultad de Ciencias Médicas de la Universidad de Guayaquil (107 hombres - 248 mujeres). Se empleó el cuestionario internacional de actividad física (IPAQ) y se aplicó el criterio de Patterson et al. (2018) para identificar el comportamiento sedentario. Para la comparación por grupos se utilizó el test no paramétrico de U Mann Whitney Wilcoxon. El impacto de la pandemia Covid-19 se manifiesta con prevalencias de un 68.3% de sujetos inactivos y un 31.7% de personas activas. Prevalecen los estudiantes sedentarios (62.2%) por sobre los sujetos no-sedentarios (37.8%), existiendo diferencias significativas por sexo (p-valor: ≤ 0.05) validadas por el tamaño del efecto y la potencia estadística. Los niveles de AF y sedentarismo superan las estimaciones mundiales de la World Health Organization por lo que se impone el asumir políticas universitarias de salud orientadas a mitigar la pandemia de la inactividad física.

Objetivo: Evaluar el rendimiento de la producción de etanol a partir de melón de descarte del mercado La Hermelinda de la ciudad de Trujillo. Materiales y métodos: Diseño no experimental, descriptivo y transversal, se trabajó con una muestra de 50 Kg de melón de descarte, por ser la fruta más abundante de la estación. Luego de la selección y limpieza de las frutas se obtuvieron 34.450 Kg de pulpa, que produjeron 17 litros de jugo con 8.5° Brix y pH 4.0. El jugo de melón fue suplementado con 1. 03 Kg de azúcar doméstica, para elevar el Brix a 13°, y se desinfectó con Bisulfito de sodio. El proceso de fermentación se llevó a cabo a temperatura ambiental (20 ± 2°C) en condiciones anaeróbicas, durante 10 días con cultivo de Saccharomyces cerevisiae. Resultados: Se obtuvieron 14 litros de mosto fermentación. Se siguió dos métodos de destilación, a partir de un litro de mosto cada uno: A, realizado a 87 °C, 1 atm de presión, durante dos horas, y B a 85 °C, 1.5 atm, durante tres horas. Para comparar las medias del etanol obtenido por destilación se aplicó la prueba t de Student con 95% de confianza, obteniendo un valor p de 0.103, que indica que no hay diferencia en la producción del volumen de etanol en ambos procesos, sin embargo, hay diferencia significativa en la concentración de etanol (p<0.001), obtenida en el proceso B (66%). Conclusiones: El melón de descarte es una buena alternativa para la producción de etanol con un rendimiento promedio de 1864.28 Litros de etanol/tonelada de melón.

Published: November 2022

Se determinó la influencia de los factores condicionantes del servicio público de agua potable sobre la efectividad del servicio en el Cantón Santa Lucía, Provincia Guayas-Ecuador, 2022. La estrategia fue cuantitativa, consultándose mediante un cuestionario (α: 0.978) a 150 stakeholders (líderes comunitarios) vinculados a la gestión y disfrute del servicio público de agua potable. La influencia se determinó con la prueba de correlación tipo Rho de Spearman, y la magnitud de la misma fue calculada a partir del tamaño del efecto (SE). Se emplearon los software SPSS V.24 y G*Power 3.1. Se partió del supuesto de que los factores condicionantes del servicio público de agua potable incidían positiva y significativamente en la efectividad del servicio. El análisis confirma que estos factores tienen una incidencia positiva, significativa y alta en la efectividad del servicio en el Cantón Santa Lucía (Rho=0.815, p-valor=0.000; SE > 0.5). El desglose por factores confirmó lo anterior (Rho p-valor= ≤ 0.05; SE > 0.5). Los factores normativos evidenciaron relaciones significativas con todas las dos dimensiones de la efectividad del servicio: cobertura de la demanda y economía del servicio. Se pudo evidenciar también, mediante la Rho de Spearman, que los factores técnicos también influyen sobre todas las dimensiones de la efectividad del servicio público, situación que fue apreciada de igual manera para con los factores económicos. En términos de planificación pública convendría incorporar a los stakeholders en todos los procesos inherentes a la misma. De esta forma se generarían co-responsabilidades y se estimularía la co-gestión.

Background and purpose: Prunus spinose L. is a traditionally consumed, recently scientifically reexamined plant. Brain bioavailability and functionality of polyphenols (PPH) of blackthorn flower extract (PSE) was investigated.Materials and methods: C57BL/6 mice received oral daily repeated doses of 25 mg/kg body weight of total PSE polyphenols for 28 days. Brain concentrations of individual polyphenols from PSE were determined by UPLC/MS on 1st,7th, 14th, 21st, and 28th day. Brain antioxidative defense markers were examined as indicators of functionality after bioaccumulation.Results: A total of 68.7% PPH present in PSE were detected in the brain. Higher (p≤0.05) Cmax/AUClast in the PSE treatment vs. control group was recorded for 59.1% of brain detected compounds, indicating relatively good bioaccumulation in the brain. The highest present compounds in PSE were not necessarily the ones mostly bioapsorbed in the brain. Kaempherols were not significantly distributed, opposite to phenolic acids, quercetins or epicgaloatechin-3-gallate. The compounds with the highest concentrations on 28th day were 4-p-coumaroylquinonic acid, (-)-epicatechin, quercetin-3-O-rutinoside, quercetin–rhamnoside, kaempherol-3-rutinoside and quercetin-3-gucoside. Brain lipid peroxidation (MDA) decreased (p<0.05) on the 21st and 28th day in the PSE group. Increase (p<0.05) in GSH concentration was observed on the 21st and 28th and SOD activity on the 28th day. Catalase activity was unchanged. It could be hypothesized that highest PPH concentration-ratios, caused reduction of lipid peroxidation by radical scavenging and simultaneous induction of glutathione and SOD pathways.Conclusions: Screened compounds could be candidates for examining or creation of brain targeted “neuro-nutriceuticals” polyphenol mixtures.

Published: November 2022

Background and purpose: The effect of weather on people’s well-being and health has been previously noticed and has been a subject of interest for medical professionals and laypeople throughout human history. There are many studies connecting gynecology and obstetrics with weather, some of them investigating the weather and physiological processes such as onset of labor.Materials and methods: In this paper we tried to find relationship between weather conditions and the day with extreme number of deliveries with spontaneous onset (contractions and/or rupture of membranes) in a tertiary referral perinatal center. It is still debatable whether we could connect the weather conditions with actual childbirth.Results: A case analysis shows that there could be a connection between the development of the weather situation and the extreme number of deliveries with spontaneous onset.Conclusion: Unfavorable biometeorological conditions were the result of weather conditions that affect people. In our case there was strong cold advection during the analyzed period, especially on the day with an extreme number of deliveries with spontaneous onset, and significant drop of barometric pressure.
Development of strain-specific SCAR primers to beneficial rhizobacteria Bacillus subtilis OSU-142
Authors: Eroglu Seckin
Published: November 2022

Background and purpose: Synthetic fertilizers damage the environment. Biofertilizers that consist of microorganisms emerge as an environmentally friendly alternative. Biofertilizers improve plant growth by mobilizing soil nutrients, triggering plant hormone synthesis, or competing with pathogenic bacteria. However, biofertilizers often fail due to insufficient colonization of the plant roots.Materials and methods: To explore the colonization dynamics of a bacterial strain commonly used in biofertilizers, Bacillus subtilis OSU-142 (OSU-142), developing a set of primers specific to OSU-142 was aimed. Since its genome is unknown, to identify genomic regions unique to OSU-142 strain, DNAs of more than 40 bacterial strains were fingerprinted, most of which belong to Bacillus subtilis using the Randomly Amplified Polymorphic DNA (RAPD) method.Results: This approach identified a polymorphic band at 880 bp, which was then cloned and sequenced. The sequence showed no perfect match to any known sequences in the tested genomic databases indicating that the region of OSU-142 DNA is highly unique. The primer was converted to Sequence-Characterized Amplified Region (SCAR) primers, and its functionality in detecting OSU-142 genome was confirmed. Newly designed primer set can specifically detect OSU-142.Conclusions: These primers can be useful for basic science or commercial applications on tracking OSU-142 in various environments, thus contributing to biofertilizers’ adoption in the long run.
A New Interpretation of the Traditional Ethnic Rational Spirit Presented by Ancient Chinese Myths
Authors: Wang Xiaoyu
Published: November 2022

Ancient Chinese myths are the source of Chinese culture, contain the emotions and thoughts shared by the Chinese nation, and embody the spiritual soul of the Chinese nation. Ancient Chinese mythology is deeply rooted in China's long-standing cultural soil. It is a unique myth that grew up in China, and it permeates the light of oriental wisdom. Purposefully and selectively inheriting the precious spiritual cultural heritage in mythology has positive practical significance for us. The content of ancient Chinese myths is rich and allencompassing. The main feature is that it advocates reason and morality, and emphasizes ethics. It conveys the spirit of dedication, fighting and struggle of the primitive people in the confrontation with the natural and social environment. This kind of spirit allows people to draw strength and courage from it, so that human beings can go through all kinds of difficulties and come to today with a smile. This paper mainly uses the method of literature analysis to excavate and sort out the salient features of the concept of rationality in ancient Chinese mythology, try to judge and reflect on ancient mythology with today's value and vision, and provide theoretical and practical support for the promotion of our country's traditional culture and national spirit and historical references.

Published: November 2022

Background: The impact of SARS-COV-2 virus (COVID-19) has been well documented in international settings with a reduction in overall emergency presentations both influenced by social distancing and lockdowns. This study focuses on several common acute general surgical pathologies exploring differences in presentations and clinical outcomes for appendicitis, cholecystitis, and incarcerated hernias during the first wave.Methods: A retrospective review of medical records of all patients was analysed in two groups: the non-COVID-19 group (combined 2017-2019) and the COVID-19 group (2020).Results: There were 3,316 acute emergency surgical presentations with an 8.2% decrease in total presentations in 2020. There were 477 appendicectomies, 224 cholecystectomies, and 121 repair of incarcerated hernias. All general surgical procedures demonstrated significant differences between non-COVID and COVID cohorts, including length of stay (LoS) (2.7 vs. 2.1, p=0.009) and onset of symptoms (1.6 vs. 2.2, p=0.018) for those aged less than 25 years. Patients with appendicitis aged less than 25 years had a significantly longer onset of symptoms before hospital presentation and shorter LoS in the COVID group (1.7 vs. 2.5, p=0.002; 2.9 vs. 2.3, p=0.016). Likewise, patients with cholecystitis had a significantly longer onset of symptoms in the COVID-19 cohort compared to their counterparts (2.0 vs. 3.0 days, p=0.025). There were no significant differences in biochemical, clinical or post-operative outcomes.Conclusions: The first wave of the COVID-19 pandemic significantly reduced acute general surgical presentations. For those less than 25 years in the COVID-19 cohort, overall LoS was shorter despite indicating significantly delayed presentations.

Published: November 2022

Background: The current study reports the clinical outcomes of the efficacy of computerized tomography (CT) guided cryoablation (CA) in the treatment of patients with small renal masses.Methods: This retrospective single institution study analyses the clinical outcomes of 36 renal tumours that were managed with cryoablation. Patient age, sex, tumour size, complications and recurrences were recorded. These patients were followed up at 3,6- and 12-months interval, they underwent biopsy and abdominal contrast enhanced ultrasound (CEUS) depending upon indications.Results: 36 patients (63.9% male, 19.4% female) each with a single small renal mass had CA with a follow-up at 3, 6 and 12 months. The mean tumour size was 606.9±31.8 mm2. Eleven complications occurred in 36 patients, for an overall complication rate of 30.6%. One (2.7%) patient had enhancement at the surgical bed on initial imaging and were considered incomplete ablations. None of the patients showed signs of distant metastases at the 3, 6 and 12-month follow-ups.Conclusions: Cryoablation of renal masses results in acceptable oncologic efficacy with an acceptable number of complications. Therefore, it remains a viable treatment for renal masses.

Published: November 2022

Background: Endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy (LC) remains the cornerstone of treatment worldwide for coexisting CBD and gall bladder calculi. The interval between ERCP and LC is disputed. In our study, LC is performed at or more than 6 weeks after ERCP keeping in view by allowing the gall bladder to recover from the acute inflammatory changes if operated upon earlier.Methods: We conducted a prospective observational study in the postgraduate department of general surgery government medical college Srinagar J and K India over a period of 2 years. The 25 patients above age of 18 years and with cholecysto-choledocholithiasis who underwent ERCP and LC at or more than 6 weeks were included.Results: In our study the mean age was 45.3 years. Male: female ratio was 1:3.2. the distribution of patients as per Nassar grading scale 1 (4%) patient had grade I,12 (48%) patients had grade II, 5 (20%) patients had grade III and 7 (28%) patients had grade IV. In patients with grade I, the mean duration of surgery was 36.0 minutes, in grade II the duration of surgery ranged from 34-60 minutes with mean duration of surgery of 43.4 min (SD±8.9), in grade III duration of surgery ranged from 42-68 minutes with mean duration of surgery of 55.2 min (SD±10.06) and in grade IV duration of surgery ranged from 68-116 minutes with mean duration of surgery of 91.3 min (SD±17.66). We observed a definite relationship between the intraoperative Nassar grading scale and the post ERCP interval, 1 patient of grade I scale operated at 12 weeks post ERCP. 12 patients were between the post ERCP interval of 8-12 weeks (mean 10.1 weeks) and they had grade II. In grade III we had 5 patients with post ERCP interval of 7-11 weeks (mean 9.2 weeks). In grade IV we had 7 patients with post ERCP interval of 6-10 weeks (mean 7.9 weeks). p=0.008.Conclusions: Interval LC after ERCP is safe but challenging, longer the interval time between ERCP and LC lesser the chances of encountering intra-operative complications. We recommend LC more than 6 weeks after ERCP is safe.

Vaccinations against COVID-19 are frequently given intramuscularly to the arm. After receiving the COVID-19 vaccine, axillary lymphadenopathy has been documented as an adverse reaction. The occurrence of ipsilateral (or contralateral) lymphadenopathy in individuals with breast cancer who got the COVID-19 immunization creates a diagnostic conundrum. This systematic study aims to assess the prevalence and clinical features of vaccine associated hypermetabolic axillary lymphadenopathy (VAHL) after COVID-19 vaccination. The PRISMA protocol was followed in conducting the systematic review. "Vaccine" or "vaccination" and "lymphadenopathy" or "lymph node" and "COVID-19" were the search phrases used. Using the predefined keywords from the systematic review procedure, 33 papers or reports were found. After irrelevant materials (such as regulations, reviews, opinions, and critiques) were eliminated, ten articles or reports were included in the evaluation. After receiving the COVID-19 vaccine, 91/22,532 cases (0.4% of cases overall) of clinically detectable lymphadenopathy were found. The axillary lymphadenopathy linked with the vaccination had a mean size of 18.2 mm (range 16–21 mm). The median time between receiving a vaccine and developing axillary lymphadenopathy was 6.9 days (range 2–18 days). 119-patient research found that enlarged axillary lymphadenopathy clears up in 4 to 5 weeks. Axillary lymphadenopathy linked to vaccines is relatively prevalent. Its management is based on a multidisciplinary assessment considering the patient's demographics, immunization history, and radiological findings. Additional imaging and biopsies can increase the demand for healthcare services. Proper timing and lateral arrangement of immunization and imaging should be encouraged to prevent ambiguity and patient concern.

Around one fifth of COVID-19 patients progress to develop acute respiratory distress syndrome. This cohort carries the highest morbidity and mortality, and the greatest treatment challenges. They are more likely to require mechanical ventilation. Thoracic air leak has been noted to be more prevalent in this group of patients. This study aims to explore the relationship between ventilator settings and the development of air leak as possible triggers, and the basic pathophysiological concepts behind its development, as well as preventive strategies. In this case series the data of all patients admitted with COVID-19 pneumonia to Khoula hospital intensive care unit (ICU) during the period from March 1st, 2020 to July 31st, 2021 were collected retrospectively and analyzed. Fourteen patients representing 7.1% out of the 196 ICU admissions had demonstrated one or more air leak manifestation. Male to female incidence was 3:1 and the mean age was 53 years. The 71.4% of these patients had received mechanical ventilation, 14.3% of them received continuous positive airway pressure (CPAP), and 14.3% just received oxygen supplementation via plain face mask. The average ventilation to air leak development time is around 7.6 days (95% CI: 1.9-13.4%).  In conclusion, although the majority of the patients who had air leak were mechanically ventilated, the condition can develop in non-ventilated and even spontaneously breathing COVID-19 patients, and no specific ventilator measure could be blamed for its development. Lung-protective ventilation strategies and accurate timing for escalation of respiratory support are the mainstay for prevention.

Polyorchidism is a rare congenital anomaly characterized by the presence of more than two testes. Triorchidism is the most common variant. Polyorchidism has been reported in around two hundred cases in the world to date. It is usually diagnosed incidentally in routine exams or surgery. It can be associated with undescended testis (40%), hernia (30%), and torsion (15%), among others. Given how rare it is, polyorchidism requires a high degree of suspicion. The exact aetiology of polyorchidism is unknown. The preservation of supernumerary testis has been controversial. Today, in the absence of pain, conservative management with a strict ultrasound and magnetic resonance imaging (MRI) follow-up is the most widely used approach. We present a case of a 48-year-old man who had a personal history of left cryptorchidism and came to our appointment with a bilateral inguinal hernia. During surgery for hernia repair, we found a supernumerary testis located on the left inguinal region with no epididymis or vas deferens. We opted for orchidopexy. In the other left testis, we did an orchidectomy due to the presence of a suspicious nodule. The histology was negative for neoplasia.

Jejunal diverticula is a rare condition, usually remains asymptomatic though sometimes presents as vague abdominal pain and in the rare case may present as a life-threatening gastrointestinal (GI) bleed. In this case, the patient presented with features of subacute intestinal obstruction and contrast enhanced computed tomography (CECT) abdomen suggested intraluminal obstruction due to impacted bone in the small bowel. The patient underwent exploratory laparotomy, there were jejunal diverticula with bone as a foreign body, and a was ileal stricture causing an obstruction. Jejunal diverticula with bone as a foreign body is a rare case, requiring high suspicion index and relevant investigations for reaching a diagnosis.

Authors: Safar Heba , Eldeeb Wesam
Published: November 2022

Background: With a focus on the consequences of caesarean delivery as a result of mother stress and the first wave of the COVID-19 epidemic as a source of maternal stress, the study sought to identify reference values for pulse oximetry recordings among both healthy full-term neonates  and preterm and unhealthy neonates.Methods: A comparative study of 170 neonates admitted to the Fayoum university NICU after being born in the department of obstetrics and gynaecology. Collected pulse oximetry readings at predetermined intervals was done. Patients were classified into group I (before 1st wave of COVID-19 pandemic) and group II (during 1st wave of COVID-19 pandemic).Results: The 5th and 95th percentiles of SpO2 after 1 minute after birth were (65% to 90%), with a mean of 77%, according to the study of 146 full-term healthy newborns. SpO2 readings were (89% to 97.1%) with a mean of 92% after 5 minutes, and finally (90% to 98%) with a mean of 93% after 10 minutes. Statistically significant lower means of SpO2 were found during 1st wave of COVID-19 pandemic after 10 minutes of delivery, and for Apgar score after 1 and 5 minutes of delivery. There was a negative impact of cesarean section delivery on gestational age.Conclusions: This research reveals that after 10 minutes of delivery, a Spo2 recorded range of 90 to 98 for full-term healthy neonates and a mean of 86% for preterm and ill neonates may be appropriate. The first wave of the COVID-19 pandemic had a deleterious impact on neonates' SpO2 recordings and Apgar scores, according to the study. There was a gestational age effect associated with caesarean delivery.

Background: Junk foods typically contain high calories from sugar or fat with little protein, vitamins, or minerals. This study was conducted to determine the consumption and prevalence of junk food consumed among school-age adolescents. The main aims of this study were to find out the junk food consumption among school-age adolescents (5-18) in Kanakasundari rural municipality.Methods: This was analytical cross-sectional research. The total sample size for the study was 280. Purposive sampling was used to select the schools and census was used to select the students from the schools. A self-administered semi-structured questionnaire in Nepali version was used to collect the data and the collected data were entered and analysed in SPSS using simple statistical methods.Results: Among the 280 respondents, the mean age was 15.17 years. The consumption of junk food among adolescents was 45 percent among males and 55 percent among females. Religion (p=0.011) and type of family (p=0.034) were significantly associated with junk food consumption. The participants following Hindu religion were 3.43 times more likely to be consume junk food (COR=3.430, 95% CI=1.256-9.366) as compared to non-Hindu. Participants residing in joint family were less likely to consume junk food (COR=0.490, 95% CI=0.252-0.954) as compared to nuclear family.Conclusions: Majority of children consumed junk food regularly; the majority preferred it for taste and some were influenced by advertisements. There is a great need to maintain healthy eating habits among adolescents to decrease the health risk associated with frequent junk food.

Background: Adolescence is the lifespan between childhood and adulthood from ages 10 to 19 years. Psychological problem is a state of emotional and behavioral disorders, including depression, anxiety, aggression, educational difficulties, etc. The study aimed to assess the impact of associated factors on adolescents’ psychosocial problems.Methods: Analytical cross-sectional and quantitative method was used. The study population was adolescents in grades 8 and 9. Purposive sampling was used to select the schools and the census technique was used to collect the data from respondents. A structured questionnaire was designed and administered to study participants. Data collected from respondents were analysed and expressed using Epidata 3.1 and SPSS 26.Results: The study shows that the prevalence of psychosocial problems among adolescents was 32.4%. The adolescent age group was greatly dominated by the age group 14-15 years (72.1%) and most of the respondents were female (52%). There was a significant association between the bad relationships with siblings (OR=5.840, 95% CI=1.820-18.735, p value=0.003), neighbors (OR=4.46, 95% CI=1.36-14.60, p value=0.013), classmates (OR=3.630, 95% CI=1.060-12.424, p value=0.040) and fine relationship with teachers (OR=5.091, 95% CI=2.223-11.658, p value<0.001) and those not satisfied with pocket money (OR= 2.833, 95% CI=1.227-6.544, p value=0.015) with the psychosocial problem.Conclusions: The update and revision of mental health policy and increment in the allocation of the health budget are crucial for improving mental health. The school can help by introducing child to parent approach to decrease the prevalence of psychosocial problems through a different awareness program and proper knowledge.
Spike in peptic ulcer disease in pregnancy in a rural community of Enugu state, southeast Nigeria: is this an epidemic?
Authors: Umegbolu Emmanuel I.
Published: November 2022

Background: Pregnancy is said to increase susceptibility to Helicobacter pylori (H. pylori) infection, probably due to decreased cell-mediated cytotoxic immune response. Despite this, evidence from epidemiological studies suggest an alleviation of peptic ulcer disease (PUD) during pregnancy. One study found the incidence of PUD among pregnant women to be as low as 0.005-0.03%. The present study aimed to determine the incidence of PUD in women who attended ante-natal clinic in Cottage Hospital Inyi, Oji River Local Government Area (LGA), Enugu State, in 2021.Methods: This was a cross-sectional study conducted with 435 pregnant women, aged 18- 40 years in 2021 in Inyi, Oji River LGA of Enugu State, Southeast Nigeria. Through purposeful sampling, 57 women were selected. From each of these patients, a stool sample was collected and examined using immunochemical fecal occult blood test. A horizontal line on the test strip signified a positive result, while its absence negative result. Data were analysed as proportion and Chi- square using MaxStat (version 3.6) statistical software. P value ≤0.05 was considered significant.Results: The incidence of PUD in the pregnant women was 13%; 4.8% in primigravidae, and 8.2% in multigravidae. The association between PUD and parity was not significant (p value =0.89).Conclusions: The incidence of PUD in pregnancy (13%) was much higher than ever had been reported in the past, being slightly higher in multigravidae than primigravidae. Health education on lifestyle modification and environmental sanitation could help in tackling this problem.
