Performance of solar still units and enhancement techniques: A review investigation.

Drinking water requirements are rapidly increasing while the availability of drinking water is decreasing. Overcoming this problem requires a sustainable energy source, such as solar energy, to desalinate untreated water. The most essential and simplest application of brackish water desalination is solar distillation.

Heart Rate Variability and Coronary Artery Bypass Grafting: A Systematic Review.

Background: Coronary artery bypass grafting (CABG) is a well-established surgical procedure used to treat significant coronary artery disease. Nevertheless, unfavorable cardiovascular events and complications, including cardiac arrhythmias may be observed in patients after CABG. Previous studies have revealed a relationship between risk of cardiac arrhythmias and abnormal heart rate variability (HRV), which reflects adverse alterations in cardiac autonomic functioning, that may occur in patients after a CABG procedure.

Donor-derived cell free DNA as a biomarker in kidney transplantation.

The early detection of acute rejection in the allograft is important as it provides an opportunity for timely therapeutic intervention in order to preserve graft function and achieve longer graft survival. Donor-derived cell-free DNA (dd-cfDNA) has emerged as a new biomarker in the field of kidney transplantation. In this review, we used data from various studies to examine the role of dd-cfDNA in comparison to creatinine and donor-specific antibodies in the early detection of transplant rejection.

A new modified limited incision for superficial parotidectomy compared to modified Blair's incision.

Background: Many incisions have been used to perform parotidectomy, but they result in a visible scar on the neck and may cause patient dissatisfaction by producing disfigurement sometimes.

Aim Of Study: The aim of this study is to use a modified limited incision for superficial parotidectomy as an alternative to the classical incision, with no obvious scarring and without affecting the identification of the facial nerve, resulting in better cosmesis.

Patients And Methods: A prospective comparative study on 100 patients has undergone superficial parotidectomy using a modified limited incision and another 100 patients who have undergone superficial parotidectomy using the modified Blair's incision (control group) for variant benign pathologies.

Emerging Therapies for Antibody-Mediated Rejection in Kidney Transplantation.

Despite the advances in immunosuppressive medications, antibody-mediated rejection (AMR) continues to be a major cause of kidney allograft failure and remains a barrier to improving long-term allograft survival. Recently, there have been significant advances in the understanding of the pathophysiological process of AMR, along with the development of new therapeutic options. Additionally, surveillance protocols with donor-derived cell-free DNA and gene profile testing have been established, leading to the early detection of AMR.

The Perspectives of General Nephrologists Toward Transitions of Care and Management of Failing Kidney Transplants.

The management of failing kidney allograft and transition of care to general nephrologists (GN) remain a complex process. The Kidney Pancreas Community of Practice (KPCOP) Failing Allograft Workgroup designed and distributed a survey to GN between May and September 2021. Participants were invited via mail and email invitations.

The association of center volume with transplant outcomes in selected high-risk groups in kidney transplantation.

Background: In context of increasing complexity and risk of deceased kidney donors and transplant recipients, the impact of center volume (CV) on the outcomes of high-risk kidney transplants(KT) has not been well determined.

Methods: We examined the association of CV and outcomes among 285 U.S.

Neuroimaging Studies of the Neural Correlates of Heart Rate Variability: A Systematic Review.

Direct and indirect links between brain regions and cardiac function have been reported. We performed a systematic literature review to summarize current knowledge regarding the associations of heart rate variability (HRV) and brain region morphology, activity and connectivity involved in autonomic control at rest in healthy subjects. Both positive and negative correlations of cortical thickness and gray matter volumes of brain structures with HRV were observed.

Technical and economic feasibility analysis of a PV grid-connected system installed on a university campus in Iraq.

In this article, a technical-economic study has been displayed to evaluate the productivity of grid-connected photovoltaic (PV) solar system in a campus of University of Zakho, Iraq. The feasibility of this study is based on performance ratio, capacity factor, cost of energy and yield factor. The analysis of the system has been performed using System Advisor Model (SAM) software and real data of Zakho city that is available in national renewable energy laboratory (NREL).

Modified Halsted's operation for inguinal hernia repair: A new technique.

Background: Inguinal hernia is a frequent problem presented to surgical clinic in Iraq. Surgical treatment options for inguinal hernia are numerous, selecting the appropriate method or technique depends on different factors.

Aim Of Study: To find a new technique for open inguinal hernia repair with no recurrence even in recurrent cases, without major complications during or after surgery, and can be used even by new surgeons with little experience.

New classification of branching pattern of facial nerve during parotidectomy: A cross sectional study.

Background: Parotidectomy is one of the most frequent modes to treate tumors of parotid gland. Previous studies documented a variation in the facial nerve branching which might risk facial nerve injury during Parotidectomy.

Aim Of Study: To make a new classification system that includes a new branching pattern of facial nerve trunk that has not been described before, also to mention a simple method of how to identify the facial nerve trunk, all that will help the new surgeon in performing parotidectomy with less complications and unpredictable outcome.

The Effect of Listening to Holy Quran Recitation on Weaning Patients Receiving Mechanical Ventilation in the Intensive Care Unit: A Pilot Study.

Mechanical ventilation (MV) causes high level of stress in hospitalized patients. Weaning is the gradual process of decreasing ventilator support that in turn lead to termination of MV and increased respiratory effort, which may exacerbate symptoms and prolong MV. This study aimed to investigate the effect of listening to Holy Quran recitation (HQR) as a non-pharmacological intervention in patients during weaning from mechanical ventilation.

Five-year outcomes of preoperative chemoradiation for rectal carcinoma in Saudi population: single-institutional experience.

Objectives: Preoperative chemoradiation (CRT) followed by surgery is the standard treatment for locally advanced rectal cancer (LARC). The outcomes of preoperative CRT in Saudi patients with LARC have not been widely studied. The study reports long-term outcomes after preoperative CRT followed by curative surgery in Saudi patients with LARC.
