Interchangeable terminology and definitions of breastfeeding difficulties may inadvertently influence premature cessation of breastfeeding. Lactation failure is a distinct concept from breastfeeding cessation, and it is vital to differentiate between them, especially in educating health care professionals in communicating and supporting mothers perinatally. Comprehensively review varying terminology and definitions, providing a more nuanced understanding of lactation failure versus breastfeeding cessation, and highlighting physiological and social, emotional, mental, and commercial factors that influence breastfeeding outcomes.

Background: Human herpesvirus 8 (HHV-8) is a critical causative agent behind Kaposi sarcoma (KS), an oncogenic disease with profound consequences in immunocompromised individuals. Studies suggested HHV-8 seroprevalence in healthy populations is uncommon, but comprehensive investigations within the Middle East region remain scarce. This study aimed to bridge this knowledge gap by meticulously assessing HHV-8 seroprevalence among healthy blood donors in Qatar, leveraging serological methodologies and PCR.

This study evaluated the potential for antibody-dependent enhancement (ADE) in serum samples from patients exposed to Middle East respiratory syndrome coronavirus (MERS-CoV). Furthermore, we evaluated the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination on ADE in individuals with a MERS infection history. We performed ADE assay in sera from MERS recovered and SARS-CoV-2-vaccinated individuals using BHK cells expressing FcgRIIa, SARS-CoV-2, and MERS-CoV pseudoviruses (PVs).

Neutralizing antibodies (NAbs) are elicited after infection and vaccination and have been well studied. However, their antibody-dependent cellular cytotoxicity (ADCC) functionality is still poorly characterized. Here, we investigated ADCC activity in convalescent sera from infected patients with wild-type (WT) severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) or omicron variant compared with three coronavirus disease 2019 (COVID-19) vaccine platforms and postvaccination breakthrough infection (BTI).

The rules for writing a research report are well defined but novice writers need more clarification on writing scholarly scientific papers for publication. The purpose of this paper is to enable novice writers to confidently apply the skills of scientific writing to the development of a scholarly paper for publication. We highlight the importance of having a clearly defined question or clarity in focus before moving on to consider the components of a scholarly paper including, the question, thesis, introduction, body, discussion, conclusion and finally, an abstract.

Resistance mechanisms are a shelter for Acinetobacter baumannii to adapt to our environment which causes difficulty for the infections to be treated and WHO declares this organism on the top of pathogens priority for new drug development. The most common mechanism that develops drug resistance is the overexpression of the efflux pump, especially Resistance-nodulation-cell division (RND) family, to almost most antibiotics. The study is designed to detect RND efflux pump genes in A.

Article Synopsis
  • Heart failure (HF) is a complex disease that leads to significant global health issues, often linked to endothelial dysfunction and low nitric oxide (NO) levels, causing blood vessel constriction.
  • Recent advances in nanomedicine utilize superparamagnetic iron oxide nanoparticles (SPIONs) to develop hydrogel nanoparticles (NO-RPs) for effectively delivering NO gas, addressing the problem of its short lifespan in the body.
  • In a study using zebrafish embryos as a model for cardiac failure, researchers tested the effect of SPIONs-loaded NO-RPs on heart function after inducing injury, assessing survival rates and cardiac parameters to evaluate potential therapeutic benefits.

Shiga toxin-producing (STEC) has been identified as an important etiologic agent of human disease in Egypt. To investigate the occurrence and describe the characterization as well as prevalence of STEC in Greater Cairo hospitals as well as molecular characterization of virulence and resistance genes. Four hundred seventy clinical isolates were collected from eight hospitals and analyzed by genotypic and phenotypic methods for STEC, followed by histopathological examination and scoring of different organs lesions.

Women's health issues are complex and require collaborative efforts to unravel some of these complexities. This study aims to identify the incidence risk of Postpartum Depression (PPD) in a national sample of women in Saudi Arabia and the relationship with several health status, lifestyle, and sociodemographic factors. A cross-sectional study with an online questionnaire format assessed the risk of postpartum depression using the Edinburgh Postnatal Depression Scale (EPDS) and included several questions on postpartum health status and lifestyle factors.

Introduction: Postpartum depression is a prevalent consequence of childbirth experienced by many women. There has been evidence linking dairy intake during pregnancy with a reduction in postpartum depression symptoms. However, there is still a lack of understanding regarding the effects of postpartum dairy consumption on postpartum depression.

An ion pair-based surfactant-assisted dispersive liquid-liquid microextraction with solidification of floating organic drop (IP-SA-DLLME-SFOD) was developed for extraction of vanadium followed by spectrophotometric determination. Tannic acid (TA) and cetyl trimethylammonium bromide (CTAB) were utilized as complexing and ion-pairing agents, respectively. Using ion-pairing, TA-vanadium complex became more hydrophobic and quantitatively extracted into 1-undecanol.

Importance: In the ongoing COVID-19 pandemic, there remain unanswered questions regarding the nature and importance of the humoral immune response against other coronaviruses. Although coinfection of the Middle East respiratory syndrome coronavirus (MERS-CoV) with the SARS-CoV-2 has not been documented yet, several patients previously infected with MERS-CoV received the COVID-19 vaccine; data describing how preexisting MERS-CoV immunity may shape the response to SARS-CoV-2 following infection or vaccination are lacking.

Objective: To characterize the cross-reactive and protective humoral responses in patients exposed to both MERS-CoV infection and SARS-CoV-2 vaccination.

Unlabelled: Several precipitating factors of hepatic encephalopathy have been recognized and studied. Hepatic encephalopathy which is a frequent and grave complication of liver failure, is associated with multiple biochemical changes like high serum ammonia, mercaptan and phenol levels, low albumin levels and derangements in electrolytes. It is characterized by a range of neuronal and psychological aberrations mainly due to the inability of liver to metabolize different neurotoxic chemicals produced in the body.

Urine is considered an outstanding biological fluid for biomarker discovery, reflecting both systemic and urogenital physiology. However, analyzing the -glycome in urine in detail has been challenging due to the low abundance of glycans attached to glycoproteins compared to free oligosaccharides. Therefore, this study aims to thoroughly analyze urinary -glycome using LC-MS/MS.

Article Synopsis
  • The study investigates autoimmune antibodies in COVID-19 patients across different severity levels, noting the link between severe cases and the presence of these antibodies, particularly antinuclear antibodies (ANA).
  • In ICU patients, a small percentage exhibited strong and moderate levels of ANA, while no non-ICU patients tested positive, indicating a potential connection between severity and autoimmune responses.
  • The findings suggest that screening for autoimmune responses in COVID-19 patients could enhance patient management and that ANA-positive individuals may not be suitable for convalescent plasma therapy.
