RESUMO

Tylophora indica (Burm f.) Merrill, belong to family Asclepiadaceae, is considered to be a natural remedy with high medicinal benefits. The objective of this work is to assess the metabolomic profile of T. indica leaves enriched in alkaloids, as well as to evaluate the in vitro cytotoxicity of these leaves using the MTT assay on human breast MCF-7 and liver HepG2 cancer cell lines. Dried leaves of T. indica were extracted by sonication, using methanol containing 2 % (v/v) of acetic acid and obtained fraction was characterized by HPTLC and UPLC-MS. The UPLC-MS study yielded a preliminary identification of 32 metabolites, with tylophorine, tylophorine B, tylophorinine, and tylophorinidine being the predominant metabolites. The cytotoxicity of the extract of T. indica was evaluated on HepG2 and MCF-7 cell lines, yielding inhibitory concentration (IC50) values of 75.71 µg/mL and 69.60 µg/mL, respectively. Data suggested that the phytochemical screening clearly showed presence of numerous secondary metabolites with moderate cytotoxic efficacy. In conclusion, the future prospects of T. indica appear promising for the advancement of phytopharmaceutical-based anticancer medications, as well as for the design of contemporary pharmaceuticals in the field of cancer chemotherapy.

RESUMO

Background: Although the conventional replacement for lost teeth has been partial or full dentures, the need for a fixed, esthetic, and functional restoration makes dental implants a reliable alternative. Aim: To evaluate the initial and final stability of platelet rich fibrin coated implants using resonance frequency analyzer. Method: ology: Thirteen patients with two or more missing teeth were informed about the procedure, and a consent form was obtained after cone beam computer tomography evaluation. Blood was drawn from the anticubital area of the patient, which was centrifuged to obtain platelet-rich fibrin. In all, 26 implants were placed, among which 13 were platelet-rich fibrin-coated (test group) and 13 were without platelet-rich fibrin (control group), and implant stability quotient values were recorded. Results: The mean age of the patients was 34.4 (SD = 4.28). Majority of the patients were males (9; 69.2%) whereas there were only four (30.8%) female patients. When comparison between overall primary implant stability with and without PRF was done, the mean difference was 5.12 and this difference was not statistically significant (p = 0.221) whereas a statistically significant difference (p = 0.019) was found when comparison between overall secondary implant stability was done with and without PRF. The primary and secondary stability values for the control group were 69.18 ± 7.45 and 73.84 ± 8.21 respectively, and the primary and secondary stability values for the test group were 64.06 ± 12.66 and 81.49 ± 7.61 respectively, which showed statistically significant differences among the groups. The difference in these values signify that primary stability is more in control group whereas secondary stability is more in case group. This signifies that PRF enhances the stability of implant. Conclusion: Implants coated with platelet-rich fibrin exhibited better osseointegration than implants without platelet-rich fibrin.

RESUMO

OBJECTIVE: To compare high-para and low-para women with respect to haematological findings, determinants, and consequences secondary to anaemia. STUDY DESIGN: Descriptive cohort study. Place and Duration of the Study: Maternity and Child Hospital, Hail, Saudi Arabia and Specialist Care Hospital (private), Islamabad, Pakistan, from April 2022 to April 2023. METHODOLOGY: The study population comprised of pregnant women in the last trimester, with the exception of those women who had more than one fetus and history of haematological disease. Purposive non-probability sampling technique was adopted. Hospital data were retrieved retrospectively for the past obstetrical, contraception usage, and supplement history. Blood parameters, type of delivery, and maternofetal complications were noted down. For qualitative-variable and quantitative-variable comparisons, Chi-square test and t-test were applied, respectively. Significance level was kept at p ≤0.05. RESULTS: The frequency of severe anaemia in high-para was 52%. High parity and anaemia had a significant dose-response relationship (p <0.05). There was a significant difference (p <0.05) in blood parameters between high-para and low-para groups. Main determinants identified for anaemia were lack of intake of iron-rich food (36%) followed by inadequate intake of oral iron (25%). Preterm birth (68%) and post-partum haemorrhage (96%) were significantly associated (p <0.05) with high parity. There was a significantly high proportion (83%) of high-para women with more than 3 cesarean deliveries and admissions in ICU. CONCLUSION: High parity and anaemia had a significant dose-response relationship. High parity was the main determinant of maternal and fetal admissions in ICU. KEY WORDS: Parity, Comparison, Maternal anaemia, Haematological findings, Diet, Contraception, Cost-effective.

RESUMO

Cancer is the primary and one of the most prominent causes of the rising global mortality rate, accounting for nearly 10 million deaths annually. Specific methods have been devised to cure cancerous tumours. Effective therapeutic approaches must be developed, both at the cellular and genetic level. Immunotherapy offers promising results by providing sustained remission to patients with refractory malignancies. Genetically modified T­lymphocytic cells have emerged as a novel therapeutic approach for the treatment of solid tumours, haematological malignancies, and relapsed/refractory B­lymphocyte malignancies as a result of recent clinical trial findings; the treatment is referred to as chimeric antigen receptor T­cell therapy (CAR T­cell therapy). Leukapheresis is used to remove T­lymphocytes from the leukocytes, and CARs are created through genetic engineering. Without the aid of a major histocompatibility complex, these genetically modified receptors lyse malignant tissues by interacting directly with the carcinogen. Additionally, the outcomes of preclinical and clinical studies reveal that CAR T­cell therapy has proven to be a potential therapeutic contender against metastatic breast cancer (BCa), triple­negative, and HER 2+ve BCa. Nevertheless, unique toxicities, including (cytokine release syndrome, on/off­target tumour recognition, neurotoxicities, anaphylaxis, antigen escape in BCa, and the immunosuppressive tumour microenvironment in solid tumours, negatively impact the mechanism of action of these receptors. In this review, the potential of CAR T­cell immunotherapy and its method of destroying tumour cells is explored using data from preclinical and clinical trials, as well as providing an update on the approaches used to reduce toxicities, which may improve or broaden the effectiveness of the therapies used in BCa.

RESUMO

Objectives: The study was conducted in a tertiary educational hospital based in Riyadh to explore faculty's perception of using simulation-based teaching as part of the Cardiovascular Diploma Program (CDP) to improve patients' safety. The study, also aimed to identify the benefits and challenges of utilizing simulation. Methods: Researchers used a qualitative approach. Semi-structured interviews were conducted online with ten faculty-members. The interviews were performed between July and September in the year 2019. Authors used convenient sampling techniques for recruitment. Data were transcribed and analyzed using a framework analysis approach. Result: Data analysis showed four emergent themes, i.e., the concept of simulation (it is a risk-free environment for training), simulation for patients' safety (students first learn on the simulators and deal with patients), simulation as a safe learning environment (gives idea basic things about the working environment, knowing the symptoms of the patients, catheterizing the patient, knowing preparations for the procedure and post care), and the challenges of utilizing simulation (identify gaps between the theoretical and practical parts). Conclusion: Faculty has appreciated the role of simulation in improving patients' safety. Simulation was underutilized due to the limited time allotted for simulation and lack of adequate experienced faculty. It is recommended that simulation should be integrated into the CDP curriculum.

RESUMO

In the context of the global increase in the rate of cesarean deliveries, with an associated higher morbidity and mortality, this study aimed to investigate the role of maternal age and parity in the cesarean section rate among women in the Hail Region of Saudi Arabia. This retrospective cohort study used data collected from the labor ward of the Maternity and Child Health Hospital, Hail, over a period of 8 months, forming a cohort of 500 women. Women were categorized into four different parity classes. The results revealed that there was no significant relationship between cesarean deliveries and maternal age (p-value, 0.07). There was no significant difference in the mode of delivery between the study's parity cohort group. A significant increase in cesarean deliveries was noticed among obese women with a BMI between 35-39.9 (52.14%). This increase was even greater among those with a BMI above 40 (63.83%). Fetal distress, malpresentation and abruptio placenta were the most significant indications for CS among all age groups (p-value 0.000, 0.021, and 0.048, respectively). Conclusions: The number of cesarean deliveries has no association with parity or age. However, there was a statistically significant association with BMI, a perineal tear after previous vaginal delivery, and a history of diabetes mellitus and gestational diabetes. The most reported reasons for CS were fetal distress, malpresentation, and abruptio placenta among all age groups.

RESUMO

High parity is associated with the risk of fetomaternal complications such as gestational diabetes mellitus, hypertensive disorders, maternal anemia, preterm labor, miscarriage, postpartum hemorrhage, and perinatal and preterm mortality. The objective of the study was to compare fetomaternal complications in women of high parity with women of low parity. This involved a cohort study on a sample size of 500 women who had singleton births. Data were collected from the Maternity and Child Hospital, Ha'il, Kingdom of Saudi Arabia. Participants were classified into two groups according to parity, i.e., women of low parity and women of high parity. Socio-demographic data and pregnancy complications, such as gestational diabetes, hypertension, preeclampsia, intrauterine growth restriction, etc., were retrieved from participants' files. Participants were followed in the postnatal ward until their discharge. The results revealed that women of high parity mostly (49%) were married before 20 years of age, less educated, obese, and were of un-booked cases. Premature babies and fetal mortality are significantly high (0.000) in this group. There is a significant difference between the two groups with respect to maternal anemia, gestational diabetes mellitus, joint pain, perineal tear, miscarriage, postpartum hemorrhage, preeclampsia, vaginal tear, and cesarean section. Determinants responsible for high parity should be identified via evidence-based medicine. Public health education programs targeting couples, weight control, nutrition, and contraception would be a cost-effective strategy for reducing the risk of possible fetomaternal complications.

RESUMO

Acne vulgaris is the commonest dermatological problem internationally and nationally. Its incidence is increasing every year in the Kingdom of Saudi Arabia (KSA). Though it is not a major health issue but it significantly affects the patient cosmetically, psychologically and socially. Previous studies have shown its association with lifestyle (age, diet, stress, sleep, smoking, exercise, obesity, etc.) and family history. By simple cost-effective lifestyle modification, its occurrence and late consequences could be minimized. Few hospital-based studies are done on this issue in Hail City, KSA. Hence present cross-sectional study was designed where data was collected by Google-Form from 484 residents of Hail City. Results have revealed that 65% of our respondents were suffering from mild to moderate Acne. Thirty percent of the respondents had BMI equal to more than 30. Majority of respondents (81%) had acne on whole face. Similarly, dairy products were also consumed by more than 50%. Majority of respondents (more than 50%) took chocolates, fast foods, oily foods and sea-foods. Nuts were taken quite often by 37% of respondents. Age between 21-25 years and oily skin have a highly significant association (p = 0.000) with development of acne. Other variables that show significant association with acne were being obese, stressful, irregular menstrual cycles and excessive intake of nuts. Hence there is a need to address this issue in order to design recommendations for the general public to minimize the incidence and consequences of acne vulgaris by simple lifestyle modifications.

RESUMO

OBJECTIVE: To evaluate the effectiveness of health education programme on the knowledge of human papilloma virus among female medical students. METHODS: This quasi-experimental study was conducted in 2014 at the Princess Nourah bint Abulrahman University, Riyadh, Saudi Arabia, and comprised female medical students. An intervention programme was implemented in the form of lectures, videos, posters, etc. on human papillomavirus. SPSS 20 was used for data analysis. RESULTS: There were 535 participants in the study. There mean age was 20.3±1.3 years. After the intervention, there was a significant increase in the level of knowledge. Of all, 495(92%) students recognised avoidance of sexually transmitted disease, vaccination and screening as effective preventive measures. In comparison to pre-intervention results, significantly higher percentage of students defined risk factors: sexually transmitted disease 392(73.3%) versus 329(61.8%), and human papillomavirus 293(54.8%) versus 151(28.4%). Knowledge regarding sensitivity, 280(52.3%) after the campaign versus 160(30.1%)before, and time to perform Pap smear,229(42.8%) versus 113(21.1%),increased significantly (p<0.05). CONCLUSIONS: Health education programme was effective in improving the level of knowledge on human papillomavirus.
