ABSTRACT

Background:
High levels of stress among pregnant women have been reported during the coronavirus disease 2019 (COVID-19) pandemic because of various infection-related and lockdown measures. Concerns about safe delivery, breastfeeding, and child care may increase the risk of depression in vulnerable women during the perinatal period.

Aim:
To study the perceptions regarding child care and prevalence of perinatal depression during the COVID-19 pandemic.

Materials and Methods:
A cross-sectional community-based survey was conducted among 750 lactating mothers post delivery between September 2020 and February 2021 in 51 districts of Uttar Pradesh. A convenient purposive sampling technique was used. A semi-structured questionnaire was used to collect the socio-demographic details and perceptions regarding child care during the COVID-19 pandemic. Assessment of depression symptoms was performed with the help of patient health questionnaire 9 (PHQ-9).

Results:
A total of 440 participants were suffering from some form of depression symptoms; the majority had mild depression. Depression was found to be higher among homemakers and young mothers (age <25 years). Depression was found in more than 40% of the respondents who felt fear of COVID infection during breast feeding and hospital stay. Similarly, more than 50% of the respondents who feared unavailability of timely health services and social ignorance had depression. More than 60% of the mothers who did not have any knowledge about safe breast-feeding and child care practices had some form of depression, and the results were statistically significant.

Conclusions:
Perinatal depression is highly prevalent during the ongoing pandemic. Hence, regular screening, psychoeducation, awareness regarding safe breast feeding, and child care practices are recommended.

Published: July 2023

Background and aim
Treatment of mandibular edentulous ridge with all-on-four treatment concept is a reliable choice. However, the framework material may affect the stresses transmitted to the implant and bone.
The aim of the study was to compare stresses transferred to implant–bone interface on using glass fiber-reinforced composite (GFRC), zirconia (Zr), titanium (Ti) and poly-ether-ether-ketone (PEEK) as framework materials.

Patients and methods
Three-dimensional finite element model of completely edentulous mandible restored with four implants (two axial anterior implants and two posterior implants 30° distally tilted) connected with a framework of different materials (Zr, Ti, GFRC, and PEEK) was constructed. A unilateral axial load of 250 N was applied at the distal end of the cantilever and the resultant von Mises stresses at implant–bone interface were calculated.

Results
The lowest von Mises stresses at implant/crestal bone area was recorded with Zr framework followed by Ti then GFRC while the highest von Mises stresses were recorded with PEEK framework.

Conclusions
Within the limitations of this study, it could be concluded that the stiffer framework material transmits more stresses to the implants. The stress distribution of GFRC, as a framework material, is better than PEEK.

Authors: El-Olimy Gehan , Salem Amel 
Published: July 2023

Aim
The aim of this study was to compare the effects of two different cleansing materials on the hardness and surface roughness of conventional and three-dimensional (3D) printed denture base materials.

Materials and methods
A total of 140 specimens were tested for surface hardness and surface roughness. The samples of each denture base type (n = 70) were randomly divided into seven subgroups each of them = 10 samples. The first subgroup was stored in distilled water. Second, third, and fourth subgroups were immersed for 18, 36, and 54 days in Corega denture cleanser, respectively. Fifth, sixth, and seventh subgroups were immersed for 18, 36, and 54 days in Aloe vera, respectively.

Results
The roughness of the 3D printed denture base material was significantly lower than that of the conventional denture base material. While the hardness of the 3D printed denture base material was significantly higher than that of the conventional denture base material. For the two types of cleaning agents used, there was a nonsignificant difference in hardness of 3D printed and conventional denture base materials immersed in Corega or Aloe vera. There was a significant difference in the surface roughness of 3D printed and conventional denture base materials immersed in Corega and Aloe vera.

Conclusion
Within the limitations of this in vitro study, it was concluded that 3D printed denture base material exhibited significantly more favorable surface roughness and hardness compared to the conventional denture base material. Disinfection by immersion using Corega produced higher surface roughness values than using Aloe vera. While Corega and Aloe vera caused nonsignificant damage to the hardness of the conventional and 3D printed denture base materials.

Clinical implications
Aloe vera gel for disinfecting 3D printed and conventional denture base materials is suggested to maintain a smooth surface of the denture base. Printing denture bases is recommended because of its high hardness and low roughness could be achieved.

ObjectiveTo evaluate the impact of two energetic drinks on color stability (CS), surface roughness (SR) and microhardness (HV) of some ceramic and hybrid materials.Materials and methodsA total of 72 square-shaped samples (0.8 mm in thickness, 10 mm in width and 12 mm in length) were divided into three groups (n= 24) according to the studied materials: Celtra Duo, IPS e.max CAD/CAM and Nacera Hybrid. Each group was subdivided into three subgroups (n= 8) according to the three immersion solutions applied: artificial saliva, Hype and Power horse energetic drinks. Samples were sectioned using an Isomet 4000 (Buehler, Lake Bluff, USA) and then stored in artificial saliva for 24 h before doing the baseline color, surface roughness and microhardness measurements. For determination of color change (ΔE), a reflective spectrophotometer was used. Surface roughness (SR) testing was carried out using an optical profilometer with a built-in camera and the microhardness (HV) investigation was performed with a Microhardness Digital Tester. After 60 days of immersion in energetic drinks, these measurements for color stability, surface roughness and microhardness were repeated in the same way. Data were tabulated and analyzed using a two-way ANOVA followed by one-way ANOVA and Tukey'spost-hoctest with a significance level assigned atP≤ 0.05 for all tests.ResultsStatistical analysis revealed significant differences between studied groups for CS (P= 0.031), SR (P= 0.012) and HV (P= 0.028). Celtra Duo recorded the lowest color change (0.57 ± 0.09) and surface roughness (0.2499 ± 0.0033) and greatest microhardness (659.62 ± 6.10) with all immersion solutions. Nacera Hybrid material showed poorer values in all investigated properties compared to Celtra Duo and IPS e.max ceramics. For all studied materials, the greatest effect of immersion solutions on CS, SR and HV was exhibited by Power horse followed by Hype and artificial saliva.ConclusionsThe energetic drinks studied significantly increased SR and decreased CS and VH of Nacera Hybrid. Celtra Duo and IPS e.max CAD/CAM ceramics showed greater resistance to acidic energetic drinks compared Nacera Hybrid material.Clinical significanceIt is essential for the dentist to reinforce the awareness of patients regarding the risks of heavy consumption of energetic drinks. Nacera Hybrid material is a promising material but should not be used in esthetic restorations.

Introduction: The Rico-Fontalvo classification of chronic kidney disease associated with obesity (CKD-AO) proposes four main pathophysiological mechanisms of renal function impairment with obesity. Type 4 CKD-OA addresses the issue of obesity in patients undergoing dialysis programs. An increase in body mass index > of 30 kg/m2 in the general population is associated with a higher risk of developing cardiovascular and metabolic diseases and higher mortality. In the group of patients undergoing hemodialysis therapies, the opposite occurs.
The objective of the review: The objective is to provide the reader with an update on the effect of weight, body composition, and body mass index in patients undergoing hemodialysis therapy in the short, medium, and long term.
Methods: A systematic search was performed in PubMed (Medline, United States Library of Congress); the search was restricted to references with no publication date limit. Keywords in English were used.
Conclusion: The increase in body mass index >25 Kg/m2 in the population group of patients undergoing hemodialysis treatments has a protective effect, decreasing mortality in studies carried out with 3 to 5 years of follow-up; At a longer follow-up time (12 years), according to observational studies, an increase in body mass index >30 kg/m2 seems to have a harmful effect equal to that of the general population. The benefit of an increase in BMI >25 kg/m2 and a decrease in mortality is more significant in men, African Americans, Hispanics, and those over 65.

Published: July 2023

Abstract: Childfree reaps many pros and cons, then what is the law in Islam if a husband and wife decide not to have children. This library research study aims to explain the position of childfree (unwillingness to have children) within the framework of Islamic law by using the maqashid al-shari'ah theories. The results of this study indicate that deciding to be childfree is due to financial reasons and academic education. Having a child is not just about giving birth but also having to be prepared to create quality children so that it costs quite a lot to get a proper education. In Islamic law, marriage has several purposes, one of which is to get offspring (hifẓ an-nasl). Therefore, if a husband and wife marry and deliberately decide not to have children, then this decision is contrary to Islamic law.Keywords: Husband and wife; Childfree; Islamic Law.Abstrak: Childfree menuai banyak pro dan kontra, lalu bagaimana hukumnya dalam Islam apabila pasangan suami istri memutuskan untuk tidak memiliki anak. Penelitian studi kepustakaan (library research) ini bertujuan untuk menjelaskan kedudukan childfree (keengganan untuk memiliki keturunan) dalam kerangka hukum Islam dengan menggunakan teori maqashid al-syariah. Hasil dari penelitian ini menunjukkan bahwa memutuskan childfree karena alasan finansial dan pendidikan akademik. Memiliki anak tidak hanya sekedar melahirkan tetapi juga harus dipersiapkan untuk menciptakan anak yang berkualitas sehingga membutuhkan biaya yang cukup banyak untuk mendapatkan pendidikan yang layak. Dalam hukum Islam perkawinan memiliki beberapa tujuan, salah satunya adalah untuk mendapatkan keturunan (hifẓ an-nasl). Oleh sebab itu, apabila pasangan suami istri menikah dan memutuskan dengan sengaja untuk tidak memiliki anak maka keputusan ini bertentangan dengan hukum Islam.Kata Kunci: Suami Istri; Childfree; Hukum Islam.

Збільшення кількості даних, що генеруються щодня потребує ефективного їх зберігання, швидкого запиту до таких даних. Як правило, такі дані є багатовимірними і можуть бути представлені за допомогою моделі даних масиву. Поряд з додаванням в систему все більш і більш потужних процесорів і прискорювачів, більшість сучасних обчислювальних систем містять все більш складний стек вводу-виводу, починаючи від традиційних дискових файлових систем і закінчуючи гетерогенними прискорювачами з індивідуальним простором пам'яті. Ефективний доступ до такого складного стека вводу-виводу при обробці масивів має важливе значення для використання великої обчислювальної потужності сучасних обчислювальних платформ. Одним із ключів до досягнення такої ефективності є визначення місця генерації або зберігання даних, а також відповідний вибір відповідних стратегій представлення та обробки.
В цій роботі зосереджено на оптимізації обробки масивів у таких складних стеках вводу-виводу шляхом дослідження двох фундаментальних питань: яке представлення даних слід використовувати, і де дані повинні зберігатися та оброблятися. Таким чином, розглянуто проблему ефективної обробки даних масиву, представлено компактне сховище масивів для дискових даних, інтегруючи в нього індексацію на основі значень без втрат.
Розроблена архітектура системи зберігання масивів з інтегрованою підтримкою індексу вартості. Завдяки їй досягається реорганізація елементів в ряд користувацьких бітів і ефективне кодування індексів згідно бітів і відповідних їм значень. При цьому генерується індексоване представлення масиву, яке додає мало додаткових витрат на зберігання.
Напрямами подальших досліджень є удосконалення архітектури системи зберігання масивів з інтегрованою підтримкою індексу вартості в частині оптимізації зберігання індексів.
Проведені експерименти підтверджують можливість практичної реалізації запропонованих архітектурних рішень.
