Analysis of Correlation Between LncRNA TDRG1 Expression and its Prognosis in Cervical Carcinoma Tissues.

To explore and analyze the correlation between LncRNA TDRG1 expression degree and the prognosis of cervical carcinoma tissues. The cervical cancer tissues and para-carcinoma tissues of 106 patients with cervical carcinoma surgically removed in our hospital were chosen as specimens. LncRNA TDRG1 expression in cervical carcinoma tissues and para-carcinoma tissues was inspected by real-time fluorescence quantitative PCR, and the correlation between LncRNA TDRG1 and the clinicopathological parameters and disease prognosis was analyzed. The relative expression of LncRNA TDRG1 in cervical carcinoma tissues was critically gone up (P < 0.05) compared to para-carcinoma tissues. The relative expression of LncRNA TDRG1 in cervical carcinoma was correlated with FIGO staging, lymph node metastasis, infiltrating depth of cervical basal, and the differentiation of cancer cells (P < 0.05). According to the results of the Kaplan-Meier curve and Log-rank test, the overall survival conditions of subjects with low-lncRNA TDRG1 were superior to that of those with high-lncRNA TDRG1 expression (P < 0.05). The expression of LncRNA TDRG1 in cervical carcinoma tissues and the clinicopathological features in predicting the overall survival (OS) in sufferers with cervical carcinoma were investigated by the Cox regression model. LncRNA TDRG1 expression in cervical carcinoma tissues is tightly associated with the progression and prognosis of cervical carcinoma, which may be a latent biological indicator for clinical diagnosis and prognosis of cervical carcinoma.

Mature teratoma of liver in an adult male patient.

Teratomas are germ cell tumors occurring usually in gonadal organs. They are neoplasms composed of one or more of the three germ layers. Extragonadal teratomas are uncommonly reported in the literature. The liver is an extremely rare site for teratoma, constituting < 1% of all teratomas. The majority of the liver teratomas are found in the pediatric population with only a dozen cases reported in adults to the best of our knowledge. We present a case of a 27-year-old male with a history of abdominal pain of 5 months duration. CT scan revealed liver mass suggesting teratoma. The patient underwent cholecystectomy and segmental liver resection. Histopathology revealed mature cystic teratoma. Complete resection remains the best treatment option. Teratomas of the liver are extremely rare, constituting < 1% of all teratomas. An extensive review of the literature yielded < 50 cases of primary hepatic teratomas with only a dozen cases in adults and only two cases in males.

Susceptibility of Diabetic Patients to COVID-19 Infections: Clinico-Hematological and Complications Analysis.

BACKGROUND: Coronavirus disease 2019 has become a global health threat resulting in a catastrophic spread and more than 3.8 million deaths worldwide. It has been suggested that there is a negative influence of diabetes mellites (DM), which is a complex chronic disease, on COVID-19 severe outcomes. Other factors in diabetic patients may also contribute to COVID-19 disease outcomes, such as older age, obesity, hyperglycaemia, hypertension, and other chronic conditions. METHODS: A cohort study was conducted on the demographics, clinical information, and laboratory findings of the hospitalised COVID-19 with DM and non-DM patients were obtained from the medical records in King Faisal Specialist Hospital and Research Centre, Saudi Arabia. RESULTS: Among the study population, 108 patients had DM, and 433 were non-DM patients. Patients with DM were more likely to present symptoms such as fever (50.48%), anorexia (19.51%), dry cough (47.96%), shortness of breath (35.29%), chest pain (16.49%), and other symptoms. There was a significant decrease in the mean of haematological and biochemical parameters, such as haemoglobin, calcium, and alkaline phosphate in people with diabetes compared to non-diabetics and a considerable increase in other parameters, such as glucose, potassium, and cardiac troponin. CONCLUSIONS: According to the findings of this study, patients who have diabetes have a greater risk of developing more severe symptoms associated with COVID-19 disease. This could result in more patients being admitted to the intensive care unit as well as higher mortality rates.

Preanalytical Errors in a Hematology Laboratory: An Experience from a Tertiary Care Center.

BACKGROUND: Laboratory errors arise at any stage of testing. Detecting these inaccuracies before results are revealed might delay diagnosis and treatment, causing patient distress. Here, we studied the preanalytical errors in a hematology laboratory. METHODS: This one-year retrospective analysis was conducted at the laboratory of a tertiary care hospital and included information on blood samples that were taken for hematology tests from both outpatients and inpatients. Laboratory records included sample collection and rejection information. The type and frequency of preanalytical errors were expressed as a proportion of total errors and sample number. Microsoft Excel was utilized to enter data. The results were presented in the form of frequency tables. RESULTS: This research included 67,892 hematology samples. For preanalytical errors, 886 samples (1.3%) were discarded. The most common preanalytical error was insufficient sample (54.17%), and the least common was an empty/damaged tube (0.4%). Erroneous samples in the emergency department were mostly insufficient and clotted, whereas pediatric sample errors were caused by insufficient and diluted samples. CONCLUSION: Inadequate samples and clotted samples account for the vast majority of preanalytical factors. Insufficiency and dilutional errors were most frequent from pediatric patients. Adherence to best laboratory practices can drastically cut down on preanalytical errors.

Prevalence of Undiagnosed Iron Deficiency Anemia and Associated Factors Among Female Undergraduate Medical Students in Makkah, Saudi Arabia.

INTRODUCTION: Iron deficiency anemia is the most common type of anemia according to the World Health Organization. Females are more likely to be affected than males. There are several factors causing iron deficiency anemia, such as increased loss of iron, decreased intake of iron, and increased utilization of iron. There are limited research studies evaluating the risk factors that cause anemia among female medical students in Saudi Arabia. For this, the study aimed to identify the prevalence of undiagnosed iron deficiency anemia (IDA) among young female university students and to identify if there is any correlation between IDA and several factors including dietary habits, psychological stress, anxiety status, and body mass index. MATERIALS AND METHODS: A cross-sectional observational study was performed between October 2022 and December 2022 with a sample of 100 healthy female students aged between 19 and 23 years, who were studying at the medical colleges of Umm Al-Qura University, Saudi Arabia. Blood samples were collected to perform complete blood count and iron profile tests. Also, a survey was done to find correlation between iron deficiency anemia and dietary intake, drinks, stress, anxiety, and body mass index (BMI). Independent t-test or Mann-Whitney U test were used to compare values for non-anemic with anemic participants, and linear regression tests were used to analyze differences between non-anemic and anemic participants' dietary intake factors and stress and anxiety scores. The level of significance was set at p<0.05. RESULTS: The findings represent an overall prevalence of iron deficiency anemia in female medical students based on the lab finding results. Thus, students were divided into two following groups: anemic (13%) with hemoglobin (Hb) concentration <12 g/dL and non-anemic (84%) with Hb concentration ≥12 g/dL. When comparing the two groups, results showed significant differences in the majority of RBC indices (hematocrit {HCT}, mean corpuscular volume {MCV}, mean corpuscular hemoglobin {MCH}, red cell distribution width {RDW}) and iron profiles, p-value was <0.05. On evaluation of the different types of food consumption, the mean iron intake was around 7 mg/day, and in 65% of the participants, it was below the estimated average requirement (EAR) of iron (8.1 mg/dL). The perceived stress scale (PSS) shows that 63% of the participants experienced moderate stress and 58% reported severe anxiety by the generalized anxiety disorder (GAD) scale. In multiple linear regression, iron was positively associated with hemoglobin concentrations, whereas stress scores were negatively associated with hemoglobin concentrations. CONCLUSION: There is a relatively low prevalence of anemia and most of it was found of the microcytic type, indicating that this condition is a common health issue among local female college students. There was no independent association between stress or anxiety and hemoglobin levels.

Prevalence of depression, anxiety, stress and its relationship with knowledge about COVID-19 in medical and laboratory medicine students of Umm-Al-Qura University: a cross-sectional survey.

Introduction: Coronavirus disease 2019 (COVID-19) pandemic has continued relentlessly for over one and half years now, causing a threat to life, fear of falling sick, helplessness, anxiety, depression and, pessimism about the future. There has been an increasing concern over student mental health in higher education. Our study was designed to measure current mental health status and its relationship with sociodemographic variables and level of knowledge about COVID-19 in Saudi Arabia. Method: A cross-sectional survey was conducted among laboratory medicine students of Makkah city, Saudi Arabia from October, 2020 to January, 21. A semi-structured questionnaire was circulated through mail and What's App. Data collected included sociodemographic details and level of knowledge towards the COVID-19 among the students. Depression anxiety and stress-21 item (DASS 21) was used to assess psychological status. Result: Our study reported 51.4% depressive symptoms, 57.9% anxiety symptoms, and 48.5% stress in the study participants. History of being hospitalized with COVID-19 and ICU reported high anxiety (p = 0.0003) and depression scores (p = 0.04). Respiratory droplet as a mode of transmission revealed higher scores on anxiety subscale (p = 0.007), whereas surface contamination reported high score of stress (p = 0.004) and anxiety (p = 0.002). Knowing that COVID-19 can also clinically present with gastrointestinal symptoms was found to show high stress (p = 0.005) and anxiety (p = 0.01) scores than any other way of clinical presentation. Conclusion: COVID-19 is likely to cause negative effect on the psychological health of students.

Knowledge and Attitude toward Hemoglobinopathies in Premarital Screening Program among the General Population in the Western Region of Saudi Arabia.

The National Premarital Screening Program, which includes sickle cell disease and thalassemia, was made mandatory in 2004 by the Kingdom of Saudi Arabia (KSA), and the earlier studies have shown a poor knowledge and negative attitude toward this program in the different study groups. This study was conducted to assess the knowledge and attitudes toward premarital screening (PMS) in a randomly selected national sample of the Saudi population, 18 years and above. This was a cross-sectional study conducted in the Saudi population in the western region between July and December 2021. Valid and reliable questionnaire and data were collected from 893 participants aged ≥18 years. The χ2 test was used to ascertain if there is an association between categorical variables. Multivariate logistic regression was used to determine factors predicting satisfactory knowledge. All 893 study participants had heard about PMS with 625 (70.0%), 244 (27.3%) and 24 (2.7%) having satisfactory, fair and poor knowledge, respectively. Participants aged 26-35 years (p =0 .038), females (p < 0.001), those with higher education (p = 0.003) and employed (p = 0.004), had a better knowledge compared to other groups. Most of the participants had a positive attitude toward PMS. There is a changing trend in the knowledge and attitude toward PMS with a greater number of people wanting to go for PMS. There is also an improvement in the number of participants opting out of marriage in case of incompatibility with their future partner. However, the health education programs need to be improved regarding the hemoglobinopathies.

Anemia Burden among Hospital Attendees in Makkah, Saudi Arabia.

Background: Anemia is a major health problem in Saudi Arabia and has multiple etiologies. Many studies have been conducted in Saudi Arabia in specific population groups like school children, adolescents, university students, and females in the reproductive age group, and most have reported high prevalence of anemia. This study was conducted in a specialist hospital in Makkah city and includes all outpatients aged 15 years and above. Objective: To study the burden of anemia among hospital attendees, its stratification based on gender and age, and its severity along with the morphological types of anemia. Methods: This is a study conducted at a specialist hospital in Makkah city and one-month data were collected retrospectively from the laboratory database and include demographic and routine hematological results of complete blood count (CBC). Results: A total of 21,524 patients were included, out of which 9444 (43.9%) were males and 12020 (56.1%) were females. The overall prevalence of anemia was 38.7% (8339). Prevalence was very high in females, accounting for 68.2% (5689), whereas it was 31.8% (2650) in males. There were 39.6% (3301), 43.9% (3657), and 16.6% (1381) cases of mild, moderate, and severe anemia, respectively. In females, anemia was more prevalent in the age group of 15 to 49, which is considered as the reproductive age group. Microcytic anemia was the most prevalent type observed in this age group, accounting for 40.7% of all anemia cases. Normocytic anemia was more prevalent in the males, accounting for 52%. Conclusion: Our study showed high prevalence of anemia among the patients attending outpatient departments in a specialist hospital. Females have high prevalence of anemia when compared to male population. Microcytic anemia was the most common anemia type among females and was seen in the 15-49 age group. There is an increase in prevalence of anemia with age for males, whereas, in females, increased prevalence is observed in the reproductive age groups and the anemia prevalence maintained a steady decrease towards the 5th to the 9th decades. Normocytic anemia was more prevalent in the 5th to the 9th decades, indicating that there are more etiologies other than iron deficiency in the causation of anemia. Macrocytic anemia was the least reported anemia type. Anemia of mild and moderate severity was predominant in both genders, although severe anemia showed higher prevalence in females as compared to males. Conclusion: Our study showed high prevalence of anemia among the patients attending outpatient departments in a specialist hospital. Females have high prevalence of anemia when compared to male population. Microcytic anemia was the most common anemia type among females and was seen in the 15-49 age group. There is an increase in prevalence of anemia with age for males, whereas, in females, increased prevalence is observed in the reproductive age groups and the anemia prevalence maintained a steady decrease towards the 5th to the 9th decades. Normocytic anemia was more prevalent in the 5th to the 9th decades, indicating that there are more etiologies other than iron deficiency in the causation of anemia. Macrocytic anemia was the least reported anemia type. Anemia of mild and moderate severity was predominant in both genders, although severe anemia showed higher prevalence in females as compared to males. Conclusion. Anemia is highly prevalent in adolescents, adults, and the elderly in Makkah region. The most common cause is thought to be iron deficiency, although other causes are not uncommon. The authorities need to address the problem of prevention and reduction in anemia prevalence by taking effective measures and interventions.

Dysregulated Bradykinin: Mystery in the Pathogenesis of COVID-19.

The COVID-19 pandemic is rapidly spreading, and health care systems are being overwhelmed with the huge number of cases, with a good number of cases requiring intensive care. It has become imperative to develop safe and effective treatment strategies to improve survival. In this regard, understanding the pathogenesis of COVID-19 is highly important. Many hypotheses have been proposed, including the ACE/angiotensin-II/angiotensin receptor 1 pathway, the complement pathway, and the angiotensin-converting enzyme 2/mitochondrial assembly receptor (ACE2/MasR) pathway. SARS-CoV-2 binds to the ACE2 on the cell surface, downregulating the ACE2, and thus impairs the inactivation of bradykinin and des-Arg9-bradykinin. Bradykinin, a linear nonapeptide, is extensively distributed in plasma and different tissues. Kininogens in plasma and tissue are the main sources of the two vasoactive peptides called bradykinin and kallidin. However, the role of the dysregulated bradykinin pathway is less explored in the pathogenesis of COVID-19. Understanding the pathogenesis of COVID-19 is crucial for the development of new effective treatment approaches which interfere with these pathways. In this review, we have tried to explore the interaction between SARS-CoV-2, ACE2, bradykinin, and its metabolite des-Arg9-bradykinin in the pathogenesis of COVID-19.

Histomorphological study of placenta in gestational diabetes mellitus / Estudio histomorfológico de la placenta en diabetes mellitus gestacional

Evidence from the literature shows that well-controlled glucose levels during pregnancy are usually associated with normal placental morphology. The aim of this study was to identify the lacental changes attributed to maternal hyperglycemia. A total of 20 placentae were selected for study from a tertiary care medical center in Makkah city, Saudi Arabia. Out of 20, 10 placentae were from patients diagnosed with GDM based on IADSPG criteria, and 10 placentae were from patients with normal pregnancies without GDM. The morphometric measurements were recorded. The mean weight of GDM placentae were more than the normal placentae. Upon histopathology, significant changes such as syncytial knots, cytotrophoblastic cell proliferation, fibrinoid necrosis, stromal fibrosis, and hyalinized villi were observed in GDM placentae. GDM produces significant morphological alterations in the placentae, which might affect the developing fetus.

La evidencia de la literatura muestra que niveles de glucosa bien controlados durante el embarazo generalmente se asocian con una morfología placentaria normal. El objetivo de este estudio fue identificar los cambios placentarios atribuidos a la hiperglucemia materna. Un total de 20 placentas fueron seleccionadas para un estudio en un centro médico de atención terciaria en la ciudad de La Meca, Arabia Saudita. De 20 placentas, 10 de estas fueron de pacientes diagnosticadas con diabetes mellitus gestacional (DMG) según los criterios de IADSPG, y 10 placentas fueron de pacientes con embarazos normales sin DMG. Las mediciones morfométricas fueron registradas. El peso medio de las placentas GDM fue mayor que la placenta normal. Tras la histopatología, se observaron cambios significativos tales como nudos sincitiales, proliferación celular citotrofoblástica, necrosis fibrinoide, fibrosis estromal y vellosidades hialinizadas en placenta con DMG. La DMG produce alteraciones morfológicas significativas en las placentas, que pueden afectar al desarrollo del feto.
