Authors: Di Lollo Maria Cristina , Jorge Beatriz Maria , Alves Napoleão Anamaria 
Published: July 2023

Com o objetivo de mapear e analisar o conhecimento produzido sobre abordagens psicológicas especializadas e seus resultados em pacientes renais crônicos em hemodiálise, foi conduzida revisão de escopo cuja amostra foi composta por 23 artigos de diferentes países. Teoria cognitivo-comportamental, análise do comportamento e psicoterapia de orientação psicanalítica foram exemplos de abordagens utilizadas. Houve relato de melhoras psíquicas, no enfrentamento, na adaptação ou nas novas condições de vida durante o tratamento. Apesar dos relatos de resultados positivos, o número de estudos publicados no período e bases consultadas foi considerado pequeno. Diante dos impactos negativos causados pela DRC na saúde mental dos pacientes e das necessidades adaptativas impostas pela doença e pela hemodiálise, identifica-se a necessidade de produção e divulgação de pesquisas que explorem os resultados de suporte psicológico regular e especializado junto a esses pacientes e ofereçam subsídios para profissionais no ensino e na prática clínica.

Authors: DOS SANTOS LIMA JEISIANE , Flávia Natalice Teixeira Ataíde  
Published: July 2023

O crescimento mundial da população longeva, aliado ao reduzido número de profissionais qualificados para trabalhar com tal grupo etário são algumas das justificativas para o incentivo de trabalhos teóricos e práticos nesta direção. Objetivo: Identificar quais as intervenções psicológicas que costumeiramente são realizadas com a população de idosos e de adultos maduros. Método: As palavras-chave “intervenção psicossocial”, “manejo do comportamento”, “idoso” e “meia-idade” foram investigadas nas bases de dados da Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs), Sistema Online de Busca e Análise de Literatura Médica (MedLine) e Scholar Google. Resultados: Foram selecionados 32 artigos, os quais foram analisados de acordo com local de publicação, delineamento e permitiram a identificação de 7 categorias de intervenção, a saber: 1) Promoção de saúde; 2) Intervenções cognitivas; 3) Psicologia positiva; 4) Terapia Cognitivo-Comportamental – TCC; 5) Análise do Comportamento Aplicada – ABA; 6) Intervenções voltadas ao período de pandemia de COVID-19 e 7) Intervenções para demandas específicas. Conclusão: Há carência quanto a utilização de medidas de comportamento que sejam válidas e fidedignas e são poucos os estudos interventivos brasileiros com a população idosa nas áreas de Psicologia Positiva e de Análise do Comportamento Aplicada/Gerontologia Comportamental, dados estes que revelam que os estudos com o público idoso no Brasil ainda são recentes.

Authors: Kamarany Mohammed Amood AL , Abdulkarim Tarik , Nasser Mahfouz 
Published: July 2023

Background: The biomolecular technique namely Real-Time Polymerase Chain Reaction (RT-PCR) is very important in confirmation of coronavirus disease 2019 (COVID-19) but in progressive infection and predication of the illness severity is not used.
Objective: Therefore, the study aimed to determine the relationship between the viral load of COVID-19 infection and the severity of illness based on cycle threshold (Ct).
Methodology: The research was designed in a case series study. The study included 60 patients that were confirmed by the RT-PCR test with COVID-19 and divided into two major groups. The first major group was mild and moderate cases (n:20) that were treated at home (outpatient) and the second major group was severe and critical cases (n:40) that were treated in the isolation center (inpatient).
Results: The results showed no relationship between the viral load and severity of illness, where the minimum Ct was 14, and the maximum Ct was 36. The mean of Ct was 22 ± 7. On the other hand, the low Ct (high viral load) was reported in early detection cases. In addition , 60% (36 cases) of patients had low Ct (high viral load ; Ct ≤ 15 and ≤ 25 ) 40% of patients (24 cases) had high Ct (low viral load ; Ct ≤ 26 and ≤ 39 ) that was more than 25 Ct and less than 39 cycles . On the other mean , 95 % of first group cases (mild and moderate cases ) had high viral load based on Ct -values and 42.5 % of second group (severe and critical) had low viral load based on Ct -values. On the other hand, kinetic of viral load–based Ct where the viral load was reported in the first week as very high (low Ct 21) with a longitudinal assessment of RT-PCR test results in individuals requiring third –fourth weeks to clear COVID-19 RNA showed a significant reduction of the viral load in samples (Ct values > 30).
Conclusion: The study concluded that several factors can affect the Ct of RT-PCR (onset date, collection technique, type of swab, sampling method). Briefly, the COVID-19 RT-PCR test cannot be used as a predictor of the severity of illness.

Pearl millet [(Pennisetum glaucum (L.) R. Br.], is an important dietary food. Under and over plant population results to poor growth and Development. Farmers in Nigeria cultivates local varieties resulting to low yield. Inorganic fertilizers are costly and also results to soil pollution. Millet productions can be enhanced through appropriate cultural practices. Field experiment was conducted at Usmanu Danfodiyo University Teaching and Research Dry land Farm, Sokoto, during the 2022 Rainy season to determine effect of intra-row spacing, appropriate combination of organic and inorganic fertilize and variety for optimum yield of millet. The treatments comprises factorial combination of three intra-row spacings (40,50 and 50 cm), three fertilizer treatments: the control, 25 kg P205 and 25 kg N ha-1, FYM at 5 t ha-1 , 12.5 kg P205 plus 12.5 kg N, plus FYM at 2.5 t ha-1 and two verities (Super SOSSAT and Zango millet local variety), laid out in split plot design, Intra-row spacing and fertilizer was allocated to the main plot, varieties to sub plots. Data collected on growth and yield parameters was subjected to analysis of variance (ANOVA). The results indicated that 40 cm intra-row spacing produced higher Leaf Area Index (LAI), Panicle length (cm) and total biomass, while 25 kg P205 and 25 kg N ha-1, FYM at 5 t ha-1 , 12.5 kg P205 plus 12.5 kg N produced taller plants, higher LAI, panicle weight, 1000 grain weight, grain yield, and total biomass. Super SOSSAT produced higher LAI, Panicle length (cm), panicle weight, 1000 grain weight, grain yield and total biomass, while Zango millet variety produced taller plant and longer panicle length. 40cm intra-row spacing, application of combined organic and inorganic fertilizer at the rate of 25 kg N, P and 5 tonne-1 FYM and Super Sossat was better for optimum yield.

Authors: Aiyeola A. , Oluwole F. S. 
Published: July 2023

Introduction: One of the most prevalent gastrointestinal ailments is gastric ulcer, which is caused by an imbalance between protective and aggressive factors. Zea mays Corn is a significant cereal crop containing natural phytochemical substances that are sources of nourishment. The methanolic extract of Corn, according to a previous study, lowers stomach acidity and inhibits the percentage of gastric ulceration with no knowledge on the mechanisms involved.
Aim: This study investigated the underlying gastroprotective mechanisms of the Corn diet (ZD).
Materials and Methods: Sixty male Wistar rats were used, randomly grouped into 6; 1(Normal control), 2(Ulcerated control), 3, 4, 5 (prefed with ZD -55%, 65%, 75%) and 6 (cimetidine- 25mg/kg) for 28 days. Gastric ulcer was induced by oral administration of indomethacin (40mg/kg) and animals were sacrificed after 4 hours. The stomach was excised and cleaned, it was then homogenized and centrifuged for biochemical assays.
Results: There is a significant reduction in gastric ulcer area in all treated groups. Significant increase in gastric tissue mucin content and gastric mucosal SOD, NO and PGE2 levels and significant reduction in the MDA was observed in the ZD and cimetidine group. Histological evaluation showed tubular glands closely packed and separated from each other by laminar propia, however there is mild presence of inflammatory cells within the laminar propia in the ZD groups compared to ulcerated control group that showed moderate oedema with infiltration of inflammatory cells with mild vascular congestion in the mucosa. There is significant reduction in the macroscopic gastric mucosal lesions with percentage inhibition of 90%, 92%, 90% and 92% in the ZD (55%, 65% and 75%) and cimetidine group respectively.
Conclusion: Results obtained from this study suggests that Zm diet may have anti-ulcerogenic properties by enhancing antioxidant enzymes as well as, nitric oxide and prostaglandin E2 mechanisms.

Published: July 2023

Introduction: Immunization is one of the most cost-effective public health interventions that has saved countless children's lives. However, the disruption caused by the COVID-19 pandemic has resulted in India having 2.7 million unvaccinated children due to the interruption of regular immunization services. The present study, conducted in a tertiary-care hospital in Jaipur, Rajasthan, India, aimed to estimate the changes in vaccine coverage during the first two years of the pandemic.
Methods: This retrospective record-based ecological study was conducted at paediatric tertiary-care hospital, Jaipur. Data of number of doses of each vaccine administered to children (0-16 years) as per the National Immunization Schedule for the period January 2019 to December 2021 were retrieved from the immunization records. The study looked at the percentage change from pre-pandemic levels in 2019. Simple moving average method was used to depict the trend in vaccine doses administered.
Results: A downward trend was observed in the total doses of vaccines administered in both years 2020 and 2021, with the overall per cent change being -26.4% and -22.5%, respectively. In 2020, a maximum negative difference of -62.4% in the dose of Td (10 years) was recorded, followed by DPT Booster-2 (-51.5%), and in 2021, was recorded a maximum negative difference in the dose of Td (16 years) (-51.4%) followed by OPV-3 and Pentavalent-3 (-36.1% each).
Conclusion: The total vaccine doses administered and the majority of the vaccine under the immunization schedule have shown a negative per cent change extending till December 2021. Monitoring the catch-up immunization levels and strengthening the health system to prevent such future disruption is recommended. Also, awareness through online or offline media can be customized as per caregivers of different age groups of children.

Conjoined twinning is one of the most fascinating human malformations. The incidence of conjoined is 1:50,000 to 1:100,000 live births, with 40–60% being stillborn and about 35% of the live births not surviving beyond 24 hours. The exact incidence of conjoint twins in Nigeria is not known as there are instances of under-reporting, largely due to the relatively poor prognosis and stigmatisation associated with conjoined twinning.
We are reporting a case of thoraco-omphalophagus conjoint twins and a malformed third fetus diagnosed by ultrasound in the first trimester of pregnancy.
A set of female conjoined twins and a malformed triplet, delivered by 25-year old primigravida via emergency Caesarean Section on the 22nd May 2021 on account of PROM and fetal distress at 34/52 GA, that were admitted in our level one neonatal unit. The twins were joined at the thoraco-abdominal region. Echocardiography showed a moderate- sized Atrial Septal Defect in twin 1 and a large Ventricular Septal Defect in twin 2. MRI showed a thoraco-omphalophagus set of conjoined twins with fused xiphisternum, myocardium, pericardium, liver and small bowel.

Published: July 2023

AbstractPreschool children's reasoning regarding moral events differs according to adversity and relates to aggression. Understanding morality in young children is paramount for understanding their aggressive behaviors. The study aims to identify patterns of aggression and prosocial behavior using Latent Class Analysis (LCA) and investigate how patterns of aggression and prosocial behavior relate to reasoning about prototypic moral events. One hundred six children (Mage = 4.40 years old, SD = 0.55 years old, Range: 3.08–5.33 years old, 51% boys) enrolled in Head Start programs and their caregivers participated. In the fall caregivers completed surveys on forms (i.e., the manifestation of behavior) and functions of aggression (i.e., motivation of behavior), and prosocial behavior. The following spring children completed two moral reasoning tasks that measured children's judgment and reasoning of harm, and their attributions of transgressors' reasoning. The LCA revealed a 3‐class solution: (1) high levels of relational aggression and moderate levels of prosocial behavior (bistrategic controllers), (2) low levels of both aggression and average prosocial behavior (uninvolved), (3) high levels of all types of aggression and low levels of prosocial behavior (high aggression). Subsequent analyses suggest that uninvolved children prioritize adhering to authority over other concerns, and bistrategic controllers focused on goal‐oriented reasoning. Overall, our findings support that recognizing patterns of behavior may be useful in understanding children's moral reasoning.

AbstractTissue repair and regeneration in ischemic areas require effective strategies for angiogenesis and microcirculation reconstruction. In this research, extracellular vesicles (EVs) derived from hemangioma stem cells (HemSC) are used as bio‐functional materials for angiogenesis. In addition, a novel thermo‐sensitive hydrogel based on chitosan (CS) and modified with hyaluronic oligosaccharides (oHA), is specially developed as an ideal carrier of HemSC‐EVs. The oHA/CSgel provides a sustained‐release delivery system for EVs, enhances the angiogenic function of HemSC‐EVs, and exerts other bio‐functions to comprehensively accelerate tissue repair. The physical properties of EVs@oHA/CSgel proved to be soft, highly elastic deformable, biocompatible, and can maintain the shape and structure of EVs. In vitro co‐culture assay verifies the angiogenic effect of EVs@oHA/CSgel, and this effect is also evaluated in a diabetic wound model. Compared to untreated group, the EVs@oHA/CSgel group has only 26.9% wound area on day 14, and 226.8% blood flux mark on day 17. Pharmacological mechanisms of HemSC‐EVs are predicted by RNA‐seq, and cluster analysis of miRNAs predicted targets presents several up‐regulated biological processes involving in angiogenesis and wound healing. In conclusion, it is suggested that EVs@oHA/CSgel as a satisfying therapeutic system for microcirculation reconstruction in tissue repair.

Published: July 2023

AbstractManipulation of the electromagnetic signature in multiple wavebands is necessary and effective in civil and industrial applications. However, the integration of multispectral requirements, particularly for the bands with comparable wavelengths, challenges the design and fabrication of current compatible metamaterials. Here, a bioinspired bilevel metamaterial is proposed for multispectral manipulation involving visible, multi‐wavelength detection lasers and mid‐infrared (MIR), along with radiative cooling. The metamaterial, consisting of dual‐deck Pt disks and a SiO2 intermediate layer, is inspired by the broadband reflection splitting effect found in butterfly scales and achieves ultralow specular reflectance (average of 0.013) over the entire 0.8–1.6 µm with large scattering angles. Meanwhile, tunable visible reflection and selective dual absorption peaks in MIR can be simultaneously realized, providing structural color, effective radiative thermal dissipation at 5–8 µm and 10.6 µm laser absorption. The metamaterial is fabricated by a low‐cost colloidal lithography method combined with two patterning processes. Multispectral manipulation performances are experimentally demonstrated and a significant apparent temperature drop (maximum of 15.7 °C) compared to the reference is observed under a thermal imager. This work achieves optical response in multiple wavebands and provides a valuable way to effectively design multifunctional metamaterials inspired by nature.

AbstractDifferent from hexagonal boron nitride (hBN) sheets, the bandgap of hBN nanoribbons (BNNRs) can be changed by spatial/electrostatic confinement. It is predicted that a transverse electric field can narrow the bandgap and even cause an insulator–metal transition in BNNRs. However, experimentally introducing an overhigh electric field across the BNNR remains challenging. Here, it is theoretically and experimentally demonstrated that water adsorption greatly reduces the bandgap of zigzag‐oriented BNNRs (zBNNRs). Ab initio calculations show that water molecules can be favorably assembled within the trench between two adjacent BNNRs to form a polar ice layer, which induces a transverse equivalent electric field of over 2 V nm−1 accounting for the bandgap reduction. Field‐effect transistors are successfully fabricated from zBNNRs with different widths. The conductance of water‐adsorbed zBNNRs can be tuned over 3 orders in magnitude via modulation of the equivalent electrical field at room temperature. Furthermore, photocurrent response measurements are taken to determine the optical bandgaps of zBNNRs with water adsorption. The zBNNR with increased width can exhibit a bandgap down to 1.17 eV. This study offers fundamental insights into new routes toward realizing electronic/optoelectronic devices and circuits based on hexagonal boron nitride.
