High expression of angiotensin-converting enzyme 2 receptor (ACE-2), transmembrane protease serine (TMPRSS), and P-selectin in platelets lead to thrombosis formation in COVID-19 patients

OBJECTIVE

The purpose of the present study is to see if the presence of angiotensin-converting enzyme 2 (ACE-2), transmembrane serine protease 2 (TMPRSS), and P-selectin in platelets increases the risk of thrombosis in COVID-19 patients.

PATIENTS AND METHODS

This was a cross-sectional study conducted in the COVID-19 isolation center between January and September 2021 and comprised 61 COVID-19-infected patients, 21 of whom were in the intensive care unit (ICU) and 40 of whom were non-ICU patients (non-ICUP) in the isolation center. The coagulation profile, as well as the ACE-2, TMPRES, and P-selectin receptors, were all assessed in addition to the complete blood count (CBC). A questionnaire was also utilized to collect social and demographic data.

RESULTS

All platelet indices and coagulation profiles were significantly altered in COVID-19 ICUP and non-ICUP in this research; additionally, there is a significant association between the presence of ACE-2, P-selectin, and TMPRRS2 in COVID-19 patients with coagulation profile and platelet indices leading to hypercoagulable state.

CONCLUSIONS

In summary, the interaction of ACE-2, TMPRSS, and P-selectin in platelets appears to be a key element contributing to COVID-19 severity via their impact on thrombus development. Further investigation into these pathways may provide possible treatment targets for reducing the severe consequences of the COVID-19 infection.

Detection of Methylene Tetrahydrofolate Reductase (MTHFR C677T) Mutation among Acute Lymphoblastic Leukemia in Sudanese Patients

Background

A genetic polymorphism that causes abnormal folate metabolism may lead to genomic instability and increase susceptibility to malignancies such as Acute Lymphoblastic leukemia (ALL). The purpose of this research is to identify methylene tetrahydrofolate reductase (MTHFR C677T) (NCBI ID: 4524) mutation in ALL patients.

Methods

The study was a descriptive case-control hospital-based study with one hundred Sudanese participants divided equally into fifty (50) Sudanese ALL diagnosed patients as cases and fifty (50) Sudanese individuals as controls. The MTHFR C677T mutant allele was detected using conventional PCR, with the primer sequence of MTHFR C677T F-TGAAGGAAGGTGTCTGCGGGA R-AGGACGGTGCGGTGAGAGTG. The study was conducted from January to March 2023, and samples were collected from the Radiation and Isotops Center at Khartoum Hospital.

Results

The investigation revealed that 12 of the 50 patients in the case group (24%) had the MTHFR C677T mutant allele, and the study also revealed that there is significant correlation with the control group. There is no significant relationship between socio-demographic variables and MTHFR mutation detection in ALL patients. Also, the sociodemographic variables predictors of MTHFR mutation among ALL patients adjusted for smoking habit revealed no significant relationship.

Conclusion

According to the findings of this study, the mutant allele of the Methylene Tetra Hydro Folate Reductase C677T was detected and demonstrated varying degrees of significance. It was concluded that the MTHFR C677T gene mutation was associated with acute lymphoblastic leukemia in Sudanese patients.

Acute upper respiratory infections admissions in England and Wales

Acute respiratory infections block the bronchial and/or nasal systems' airways. These infections may present in a variety of ways, from minor symptoms like the common cold to more serious illnesses like pneumonia or lung collapse. Acute respiratory infections cause over 1.3 million infant deaths under the age of 5 each year throughout the world. Among all illnesses, respiratory infections make for 6% of the worldwide disease burden. We aimed to examine the admissions related to acute upper respiratory infections admissions in England and Wales for the period between April 1999 and April 2020. This was an ecological study using publicly available data extracted from the Hospital Episode Statistics database in England, and the Patient Episode Database for Wales for the period between April 1999 and April 2020. The acute upper respiratory infections-related hospital admissions were identified using the Tenth Revision of the International Statistical Classification of Diseases and Related Health Problems 5th Edition (used by National Health Service [NHS] to classify diseases and other health conditions) (J00-J06). The total annual number of admissions for various reasons increased by 1.09-fold (from 92,442 in 1999 to 193,236 in 2020), expressing an increase in hospital admission rate of 82.5% (from 177.30 [95% confidence interval {CI}: 176.15-178.44] in 1999 to 323.57 [95%CI: 322.13-325.01] in 2020 per 100,000 persons, P < .01). The most common causes were acute tonsillitis and acute upper respiratory infections of multiple and unspecified sites, which accounted for 43.1% and 39.4%, respectively. Hospital admissions rate due to acute upper respiratory infections increased sharply during the study period. The rates of hospital admissions were higher among those in the age group below 15 and 75 years and above for the majority of respiratory infections, with a higher incidence in females.

Self-Reported Household Waste Recycling and Segregation Practices among Families in Eastern Region of Saudi Arabia: A Cross-Sectional Study

BACKGROUND

The reuse and recycling of household waste are correlated with a household's daily activities and commonly depend on sociodemographic factors. In this study, we aimed to assess and probe the level of awareness of waste reuse and recycling, self-reported household waste recycling and segregation practices, and the variables affecting the practices of households in Al-Ahsa, Saudi Arabia.

METHODS

We employed a cross-sectional study utilizing the multi-stage random sampling of 279 households and a researcher-structured, online questionnaire in English and Arabic. Data were analyzed using SPSS Version 20. Descriptive statistics was used to describe the level of awareness/practices, and inferential statistics was used to describe the correlational aspects.

RESULTS

It was determined that female participants, younger participants, participants of both genders with university and postgraduate education levels, and urban residents were significantly associated with self-reported household waste segregation and recycling practices at the source. Plastics, paper, glass, food waste, textiles, and electronic waste were determined to be the most common types of household waste. A lack of expertise, awareness, demand for recycled products, and laws that support recycling was reported to affect female participants' failure to recycle. Social media, television, and educational institutions were shown to be sources of information regarding waste segregation and recycling. Therefore, awareness-raising polices must be developed to improve the prevalence, expertise, and efficiency regarding recycling and segregation. In addition, inventive methods, such as a card-based reward system, should be used to increase the demand level for recycled products.

Correlation between smoking and downregulation of red cell CD47 as eryptosis marker

OBJECTIVE

The purpose of this research is to discover a link between cigarette smoking and decreased red cell CD47 expression.

SUBJECTS AND METHODS

The current cross-sectional study included 72 smokers (who had smoked 20 cigarettes per day for at least two years) and 50 nonsmokers, as well as nonsmokers who had not been exposed to smokers on a regular basis and chose to participate as controls. Due to exclusion criteria, 11 participants were removed from the study; they had various genetic, immune, and metabolic disorders, leaving only 61 healthy people in the study. A flow cytometer was used to examine CD47.

RESULTS

There was a strong correlation between smoking and a decrease in CD47 markers in all types of smokers in the control samples (p-value = 0.000), as well as among cigarette smokers only (p-value = 0.000), cigarette and Shisha smokers (p-value = 0.024), and cigarette and e-cigarette smokers (p-value = 0.014). Furthermore, there is a strong correlation between the appearance of the CD47 marker in healthy smokers and smokers with non-hereditary blood diseases like iron deficiency anemia and polycythemia.

CONCLUSIONS

It can be concluded that smoking significantly reduces the expression of the CD47 marker.

E-Cigarette Use among Male Smokers in Al-Ahsa, Kingdom of Saudi Arabia: A Cross-Sectional Study

E-cigarette use is increasing globally. Recent evidence suggests that e-cigarettes contain harmful substances that could cause adverse health outcomes. This study investigated the prevalence and associated factors of e-cigarette use among male current smokers in Saudi Arabia. We conducted a cross-sectional survey of adult male current smokers in the Al-Ahsa province of Saudi Arabia. Data were collected using a structured questionnaire. We performed logistic regression analyses to investigate the factors associated with e-cigarette use among adult male current smokers. 325 current smokers participated in the study. A third of them (33.5%) were e-cigarette users. Almost all the study participants (97.0%) had heard about e-cigarettes. Participants who were occasional smokers (Odds Ratio (OR): 2.28; 95% Confidence Interval (CI): 1.17-4.41) and had good knowledge perception of e-cigarettes (OR 3.49; 95% CI: 2.07-5.90) had higher odds of using e-cigarettes when compared to regular smokers of conventional cigarettes and current smokers with poor knowledge perception of e-cigarettes, respectively. In contrast, private employees (OR: 0.25, 95% CI: 0.07-0.85), and business owners (OR: 0.09, 95% CI: 0.01-0.63) had lower odds of using e-cigarettes compared to unemployed individuals. Compared with non-e-cigarette users, the rate of conventional cigarette smoking per day was significantly lower among e-cigarette users. Use of e-cigarette (OR: 3.57, 95% CI: 2.14-5.98), believing that e-cigarette quitting is hard (OR: 2.02, 95% CI: 1.17-3.49) and trying to quit e-cigarettes (OR: 2.17, 95% CI: 1.1-4.25) were found to be significant predictors of good knowledge perception of e-cigarettes among the current smokers. The use and knowledge perception of e-cigarettes were higher among occasional conventional male cigarette smokers than regular male smokers in Al-Ahsa province. The use of e-cigarettes as smoking cessation aids should be examined further in the Saudi Arabian setting.

&lt;b&gt;Background and Objective:&lt;/b&gt; The most common genetic disease in humans is hemoglobinopathies, also known as hemoglobin hereditary diseases. The purpose of this study was to look at the hemoglobinopathy patterns in anemic patients with a history of sickle cell disease in Saudi Arabia's Eastern Province. &lt;b&gt;Materials and Methods:&lt;/b&gt; This prospective cross-sectional study was conducted on anemic patients attending the hospital with a strong family history of hemoglobinopathy and general signs and symptoms, as well as mild to moderate anemia crises. One hundred and ten people were chosen to participate in this study. The research was carried out between September, 2019 and October, 2020. &lt;b&gt;Results:&lt;/b&gt; The sickle cell trait was the most common hemoglobinopathy in males (31.1%) and sickle cell trait+beta thalassemia minor was the most common in females (18%). The gender of patients and the distribution of hemoglobinopathy types were found to have a significant relationship (p-value of 0.001). &lt;b&gt;Conclusion:&lt;/b&gt; A significant correlation was discovered between the gender of patients and the distribution of hemoglobinopathy types. More efforts must be made to raise the prevention of endogamy awareness among Saudis.

The Prevalence of unexpected antibodies in Saudi's plasma prior blood transfusion and their association with clinical conditions: A cross-sectional study

Unexpected antibodies, also called irregular antibodies, are not known to exist in a person's serum before testing. This research aims to assess the prevalence of unexpected antibodies and their correlation with several clinical conditions. This cross-sectional prospective study, undertaken from June 2019 to June 2020, included ABO, Rh grouping, cross-matching, and antibody screening. Antibody identification was performed only on patients who tested positive in the screening test. From a total of 9764 participants who were screened for unexpected antibodies, 107 (1.1%) tested positive. The Rh blood group system antibodies were the most frequent, particularly anti-D. There was also a significant correlation between the unexpected antibodies and history of transfusion, pregnancy, and autoimmune diseases as P ≤ 0.05. The most prominent unexpected antibodies in the study belong to the Rh system (Anti-D). Moreover, as a result of the strong correlation between the unexpected antibodies as well as the history of transfusion, pregnancy, and autoimmune diseases, the highest safety criteria must be followed during the transfusion of blood to patients with these clinical conditions.

Dietary knowledge, attitude and practice among type 2 diabetes mellitus patients in Sudan: a hospital-based cross-sectional study

Background

In Sudan, the prevalence of diabetes in adults was estimated at 19.1% in 2015. This study assessed dietary knowledge, attitude, and practices (KAP) of type 2 diabetes mellitus (T2DM) patients in Sudan.

Methods

We randomly selected 238 T2DM patients from a list of 2460 patients from the Jabber Abulizz Hospital. We interviewed them face-to-face using a structured questionnaire. Multivariate logistic regression analyses were performed to investigate the determinants of KAP regarding the recommended diets for T2DM patients.

Results

Majority of the patients demonstrated good knowledge (54.6%), positive attitude (79%); and good practice (58%). The result revealed that patients with formal education had 3.0 (95% CI: 1.6–5.7) times higher odds of having good diabetic dietary knowledge than those with informal education. While patients who had good knowledge and a positive attitude were respectively 4.7 (95% CI: 2.4–8.9) and 3.2 (95% CI: 1.5–6.7) times more likely to follow dietary recommendations than the patients with poor knowledge and negative attitudes.

Conclusion

Irrespective of the socio-demographic position, the good knowledge and the positive attitude towards the recommended diet, all the T2DM patients complied with the dietary recommendations. These findings highlight the need for improving knowledge and promoting positive attitudes towards the recommended diet among T2DM patients.

Communication for behavioural impact in enhancing utilization of insecticide-treated bed nets among mothers of under-five children in rural North Sudan: an experimental study

Background

Malaria is the leading cause of morbidity and mortality in Sudan. The entire population is at risk of contracting malaria to different levels. This study aimed to assess the effectiveness of communication for behavioural impact (COMBI) strategy in enhancing the utilization of long-lasting insecticidal nets (LLINs) among mothers of under-five children in rural areas.

Methods

A randomized community trial was conducted in rural area of Kosti locality, White Nile State, Sudan, among mothers of under-five children, from January 2013 to February 2014. A total of 761 mothers from 12 villages were randomly selected, 412 mothers from intervention villages and 349 were from comparison villages.

Results

The knowledge of mothers, in intervention villages, about malaria vector, personal protective measures (PPM) against malaria, and efficacy of LLINs was significantly increased from 86.9 to 97.3 %; 45.9 to 92 % and 77.7 to 96.1 % respectively. Knowledge about usefulness of PPM, types of mosquito nets and efficacy of LLINs was significantly higher in intervention villages compared to comparison villages (p < 0.05), (η² = 0.64). Mothers in intervention villages increasingly perceived, post-intervention, that malaria was a serious disease (99.3 %), a preventable disease (98.8 %) and also LLINs as an effective intervention in malaria prevention (92.2 %). This resulted in an increase in the utilization rate of LLINs from 19.2 to 82.8 % in intervention villages compared to comparison villages (p < 0.05) [OR = 4.6, 95 %, CI = (3.72–5.72)], (η² = 0.64). The average of mothers’ knowledge about malaria was increased by 64 % (η² = 0.64), the use of LLINs was increased by 79 % (η² = 0.79) and a positive attitude towards malaria was 2.25 times higher in intervention villages than among mothers in the comparison villages.

Conclusions

These results established the usefulness of COMBI strategy for increasing awareness about malaria, developing a positive perception towards malaria prevention and, increasing the utilization of LLINs.
