The Feasibility of Telemedicine in the Implementation and Management of Therapeutic Hypothermia for Infants with Neonatal Hypoxic-Ischemic Encephalopathy in a Resource-Limited Country.

Background Telemedicine is widely used in neonatal services in developed countries, though its outcomes in low- and middle-income countries are controversial. Lack of expertise and/or facilities, however, has limited its use in developing countries and around areas of military conflicts. We aim to study the implementation and management of therapeutic hypothermia (TH) in infants with hypoxic-ischemic encephalopathy (HIE) with the help of telemedicine in a resource-limited country. Methodology This is a retrospective study, evaluating patients who received TH, guided by telemedicine, through a mobile app (Telegram), an application that allows sharing and archiving of information with other beneficial features. We assessed the feasibility of utilizing telemedicine in guiding the application of TH to infants affected with HIE in the North-West of Syria between July 2020 and July 2021. Feasibility was measured by parameters related to the time gaps between initiation of consultation and treatment and clinical short-term outcomes. Results Out of 5,545 newborn infants delivered during the study period, 22 patients were eligible for TH guided by telemedicine. Patients were referred for consultation at a median (interquartile range [IQR]) of 137 (35-165) minutes of life. A median (IQR) of 12 (3-18) minutes elapsed between the call for a consultation and the consultant response and a median (IQR) of 30 (0-42) minutes elapsed between seeking the consultation and the initiation of cooling therapy. Eighteen patients completed cooling for 72 hours. The patients' temperatures were within the target range (33-34°C) most of the time (84.1%). Conclusion Telemedicine is a feasible method to guide the implementation TH for HIE in resource-limited areas. The short-term success rate is relatively high; however, further studies with a larger population are needed to confirm these findings.

The interaction between microRNA-152 and DNA methyltransferase-1 as an epigenetic prognostic biomarker in HCV-induced liver cirrhosis and HCC patients.

The necessity for early detection and hence improving the outcome of treatment of hepatocellular carcinoma (HCC) is critical especially in Hepatitis C virus (HCV)-Genotype 4 induced cases. In our current work, we examined the miRNA-152 and DNMT-1 expression in chronic liver disease (CLD) due to HCV genotype 4 infection with/without cirrhosis and HCC patients as an attempt to evaluate the potential benefits of these new circulating, noninvasive, prognostic, epigenetic markers for liver cirrhosis and carcinogenesis of Egyptian patients. Eighty subjects were included in this study, divided into two groups; group I (40 patients) were classified into subgroup Ia (CLD without cirrhosis, n = 18) and subgroup Ib (CLD with cirrhosis, n = 22), group II (CLD patients with HCC, n = 20), and control (Healthy volunteer, n = 20). The expression of miRNA-152 and DNMT-1 genes were analyzed using Real-Time PCR. MiRNA-152 showed a persistent and significant downregulation in all diseased groups, which was in consistence with the progression of the disease toward the HCC stage. DNMT-1 showed upregulation in all diseased groups when compared to control and subgroup Ia. The miRNA-152 was shown to correlate inversely with DNMT-1 in subgroup Ia, Ib and group II (r = -0.557, p < 0.01), (r = -0.850, p < 0.001) and (r = -0.544, p < 0.02) respectively. In addition, miRNA-152 and DNMT-1 showed a diagnostic ability to discriminate between cases of cirrhosis and HCC against CLD without cirrhosis (p < 0.01), while DNMT-1 did not, except between HCC and cirrhotic cases. Furthermore, both genes can be considered as predictor and prognostic parameters for cirrhosis (OR = 1.041, p = 0.043) and (OR = 1.039, p = 0.04) respectively, while miRNA-152 alone is proved as a prognostic marker for HCC (OR = 1.003, p = 0.044). Finally, the persistent reverse correlation between miRNA-152 with DNMT-1 prompts their use as noninvasive prognostic biomarkers for HCV induced liver cirrhosis and HCC in HCV Genotype 4 patients.

Child and adolescent health in northwestern Syria: findings from Healthy-Syria 2017 study.

OBJECTIVES: Since the uprising in 2011, there has been limited health-care data from inside Syria in the academic literature. This study aims to provide an updated account of pediatric health needs in the northwestern part of Syria; this should help inform the management and delivery of health-care services in this population. METHODS: This is a prospective study, using a data registry, of all pediatric patients seen in a single center in northwestern Syria, between February and December 2017. We used international classification of diseases (ICD-10) codes to define cases, and tested several covariates, including age, sex, season of the year, and conditions of living for possible correlations with major illness categories. RESULTS: We included 11,819 patients, of whom 5,288 (45%) were male and 6,531 (55%) were female. Collectively, these patients had 23,427 encounters. Respiratory diseases were the most encountered illnesses among all age groups (6320 [27%]), except late teen females, among whom gynecological/obstetric complaints dominated. Infectious diseases caused the greatest disease burden across all age groups, with upper respiratory tract infections (URTIs), infectious diarrhea, and otitis media representing almost half (47%) of all cases in this category. Nutritional deficiencies were diagnosed in 978 patients (8%), mostly in infants and toddlers (92%). We identified 1192 (17%) cases of acute diarrhea among all age groups, making it the second most common condition after URTIs. As compared to town residents, patients living in camps for internally displaced people accounted for more cases of infectious diarrhea (58%), chronic anemia (60%), and malnutrition (66%), especially severe acute malnutrition (76% of malnutrition cases). Vaccine-preventable illnesses represented a sizable category; we reported 69 cases of hepatitis A, 2 of poliomyelitis, 9 of pertussis, 37 of varicella, 11 of mumps, 8 of rubella, and 1 case of measles. CONCLUSION: We have identified urgent health-care issues in this population, including extreme malnutrition, high rates of infectious diseases, and high rates of teenage pregnancy. Also, we observed a relapse of some vaccine-preventable illnesses, such as mumps and rubella, which are likely associated with the decline in vaccination rates.

The Role of Hemostatic Factors in Atherosclerosis in Patients with Chronic Renal Disease.

INTRODUCTION: Atherosclerotic cardiovascular disease remains the leading cause of increased morbidity and mortality observed in chronic kidney disease (CKD) patients. Endothelial dysfunction (ED) is thought to be a key initial event in the development of atherosclerosis. The aim of this study was to evaluate the potential role of hemostatic factors in atherosclerosis, thrombosis and cardiovascular complications in patients suffering from chronic renal disease. METHODS: The study was conducted on 50 renal patients divided into two groups of equal size. Group 1 consisted of 25 patients with end-stage renal disease (ESRD) on regular hemodialysis. Group 2 consisted of 25 chronic renal disease patients on conservative treatment. Twenty age- and sex-matched healthy subjects were included in the study to serve as a control group. Thrombomodulin (TM), von Willebrand factor (vWF), tissue plasminogen activator (t-PA), plasminogen activator inhibitor (PAI-1) and hsCRP were assessed. High-resolution B-mode ultrasonography of both the common and internal carotid arteries to measure carotid intima media thickness (CIMT) was performed on all subjects. RESULTS: There were highly significant increases in hsCRP, TM, vWF, tPA and PAI-1 in both patient groups compared to the control group (P<0.01 for all except for TM between group 2 and 3 P<0.05) with significant increase in group 1 compared to group 2 (P<0.01). In addition, there was a highly significant increase in CIMT in both patient groups compared to the control group (P<0.01) with a significant increase in group 1 compared to group 2 (P<0.05). The study revealed significant positive correlation of hemostatic factors (TM, vWf, PAI-1 & t-PA) with creatinine, urea, hsCRP & CIMT. CONCLUSION: CKD patients have increased risk of atherosclerosis as measured by CIMT, which is used as a surrogate marker of early atherosclerosis and has been shown to be a strong predictor of future myocardial infarction and stroke. They have high levels of TM, vWF, tPA, PAI-1 that correlate with kidney function, hsCRP and CIMT. Therefore, these abnormalities in hemostasis may account for the increased risk of atherothrombosis in these patients. The elevated hsCRP levels and their correlation to hemostatic factors and CIMT might provide an important clue to link a systemic marker of inflammation to atherosclerosis. Further research is required to better understand the procoagulant state in patients with CKD.

A Possible Role for TNF-α in Coordinating Inflammation and Angiogenesis in Chronic Liver Disease and Hepatocellular Carcinoma.

BACKGROUND: Increasing evidence supports the hypothesis that chronic and persistent inflammation contributes to cancer development. However, the molecular mechanisms that lead to cancer in chronic inflammation and the role of angiogenesis in inflammation-associated cancer remain poorly understood. METHODS: NINETY PATIENTS WERE ENROLLED: 30 cases of CHC without cirrhosis, 28 cases of CHC with liver cirrhosis, and 32 cases of HCC and hepatitis C virus infection. Ten wedge liver biopsies, taken during laparoscopic cholecystectomy, served as normal controls. Serum TNF-α levels were measured using the ELISA technique; in situ hybridization and immunohistochemical studies were used to detect hepatic levels of messenger RNA (mRNA) transcripts and mature protein, respectively, for both TNF-α and VEGF. RESULTS: The highest hepatic expression of TNF-α was noticed in liver cirrhosis specimens compared to noncirrhotic CHC and HCC. Hepatic expression of VEGF and serum level of TNF-α revealed significant increases in the progression of the disease. Moreover, cases with higher grades of inflammation or stages of fibrosis showed significant increases in serum TNF-α and expression of TNF-α and VEGF. Expression of mRNA of both TNF-α and VEGF shows increasing expression with positive correlation to progression of viral hepatitis to cirrhosis with more positivity in cases developed HCC. CONCLUSIONS: VEGF signaling could be one of the molecular signaling pathways involved in TNF-α induced angiogenesis which might pose an important link between inflammation and fibrosis in CHC and HCC development and progression. Moreover, serum inflammatory biomarkers can be used to monitor the disease progression.

The role of fas/fas ligand system in the pathogenesis of liver cirrhosis and hepatocellular carcinoma.

BACKGROUND: The Fas receptor/ligand system including soluble forms is the most important apoptotic initiator in the liver. Dysregulation of this pathway may contribute to abnormal cell proliferation and cell death and is regarded as one of the mechanisms preventing the immune system from rejecting the tumor cells. OBJECTIVES: To analyze the role of Fas system Fas/ Fas ligand (Fas/ FasL) in the multi-step process of hepatic fibrosis/carcinogenesis, and to use of the serum markers as possible candidate biomarkers for early detection of hepatocellular carcinoma (HCC). PATIENTS AND METHODS: NINETY PATIENTS WERE ENROLLED: 30 cases of chronic hepatitis C (CHC) without cirrhosis, 30 cases of CHC with liver cirrhosis, and 30 cases of HCC and hepatitis V virus (HCV) infection. Ten wedge liver biopsies, taken during laparoscopic cholecystectomy, were served as normal controls. Serum soluble Fas (sFas) levels were measured using ELISA technique; Fas and FasL proteins were detected in hepatic tissue by indirect Immuno-histochemical technique (IHC); electron microscopic (EM) and immune electron microscopic examinations were performed for detection of Fas expression on lymphocytes. RESULTS: Hepatic expression of both Fas and FasL as well as expression of Fas on separated lymphocytes were significantly increased in the diseased groups (P < 0. 01) compared to the control specimens. The highest expression was noticed in CHC specimens, particularly with the necro-inflammatory activity and advancement of the fibrosis. The sFas in cirrhotic patients and HCC were significantly higher than that in normal controls and CHC without cirrhosis group (P < 0.01). CONCLUSIONS: Apoptosis and the Fas system were significantly involved in the process of converting liver cirrhosis into hepatocellular carcinoma. Down-regulation of Fas expression, up regulation of FasL expression in hepatocytes, and elevation of serum sFas levels were important in tumor evasion from immune surveillance, and in hepatic carcinogenesis.
