Acetylcholinesterase enzyme (AChE) activity is impaired by a variety of inhibitors including organophosphorus pesticides, leading to the accumulation of acetylcholine. In this study, we aimed to determine the association between cancer and the blood level of the (AChE). This is a multicenter hospital-based case–control study conducted in the Radiation and Isotopes Center Khartoum, and Institute of Nuclear Medicine and Molecular Biology and Oncology Gezira. One hundred and fifty participants, half of them cancer patients and half cancer free were recruited. All participants were screened for demographic, environmental, occupational, and clinical characteristics. Blood for the (AChE) activity test was drawn from participants in the two groups. The mean age of the participants was 40.6 ± 14.8 years. Geographical distribution showed the Central Region of Sudan had the highest rate of cancer, followed by North State, Khartoum State, West State, and East State. The most common tumor subtype was breast cancer, followed by leukemia, colon, esophageal, and prostate cancer. Inferential analysis revealed significantly impaired (AChE) activity among cancer patients compared to controls (53.4 ± 20.3% vs. 93.8 ± 8.8, p-value 0.001). There was a significant statistical association between impaired (AChE) activity and cancer. (AChE) activity might be applied in the future as a diagnostic biomarker and therapeutic target. Further large sample and molecular studies are recommended.

Background: A surgical site infection (SSI) has significant clinical, humanistic and economic consequences. Surgical antimicrobials prophylaxis (SAP) is a reliable standard to prevent SSIs. Objective: The objective was to test that the clinical pharmacist’s interventions may facilitate the implementation of SAP protocol and subsequent reduction of SSIs. Methods: This was double blinded randomized controlled interventional hospital-based-study at Khartoum State-Sudan. A total of 226 subjects underwent general surgeries at four surgical units. Subjects were randomized to interventions and controls in a (1:1) ratio where patient, assessors and physician were blinded. The surgical team has received structured educational and behavioral SAP protocol mini courses by way of directed lecturers, workshops, seminars and awareness campaigns delivered by the clinical pharmacist. The clinical pharmacist provided SAP protocol to the interventions group. The outcome measure was the primary reduction in SSIs. Results: There were (51.8%, 117/226) females, (61/113 interventions versus 56/113 controls), and (48.2%, 109/226) males (52 interventions and 57 controls). The overall rate of SSIs was assessed during 14 days post-operatively and was documented in (35.4%, 80/226). The difference in adherence to locally developed SAP protocol regarding the recommended antimicrobial was significant (P <0.001) between the interventions group (78, 69%) and the controls group (59, 52.2%). The clinical pharmacist’s implementation of the SAP protocol revealed significant differences in SSIs with reduction in SSIs from 42.5% to 25.7% versus the controls group from 57.5% to 44.2% respectively, P = 0.001 between the interventions group and the controls group respectively. Conclusion: The clinical pharmacist’s interventions were very effective in sustainable adherence to SAP protocol and subsequent reduction in SSIs within the interventions group.

Food contains several microorganisms that may cause illnesses and food poisoning in humans. Small numbers of microorganism contamination could result in rapid spoilage of food. The Centres for Disease Control and Prevention (CDC), USA estimates that 76 million people are affected by foodborne illnesses each year in the USA. Salmonella infections alone account for one billion dollars yearly in direct and indirect medical costs and more than 5,000 deaths. In Sudan, diarrhoeal disease was reported as the second major disease during the years from 2003 to 2007 (Annual health statistical report of the Federal Ministry of Health, Sudan). We aimed to develop a rapid molecular procedure for the detection of Escherichia coli, Shigella dysentery, and salmonella Typhiin food so as to minimize the public health hazard of food contamination. We used the Multiplex PCR method as rapid methods were tested for identification of Enterobacteriaceae species Escherichia coli as an indicator organism for food contamination and two strains of Enterobacteriaceae that causes food borne illness (namely Shigella dysentery and salmonella Typhi). The Multiplex PCR was performed to detect E. coli using Mdh primer pair, Salmonella Typhi using IpaB primer pair, and Shigella dysentery using IpaH1 primer pair. The sensitivity to detect E. coli, Salmonella Typhi, and Shigella dysentery in contaminated food in the concentration of the infective and the over infective doses were 100%, 96.3%, and 88.9% respectively for the three bacteria strains. There was no significant difference in the detection of the bacteria after incubation for 8 hours, 24 hours, or even without incubation period. There were no differences in the result of the samples that were contaminated artificially in laboratory and those obtained from the market. The Multiplex PCR method for identification of E. coli, Salmonella Typhi and Shigella dysentery was developed as a model for detection and risk assessment of the three bacteria in one program, and it is suitable for routine analysis.

There have been multiple reports of patients with coronavirus disease (COVID-19) testing positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) after discharge; however, information on the characteristics of such cases is limited. In this case report, we aimed to identify clinical and epidemiological characteristics of patients who had a repeat positive polymerase chain reaction (PCR) test for SARS-CoV-2. We analyzed data of 22 COVID-19 patients who tested positive for SARS-CoV-2 on polymerase chain reaction (PCR) testing after two consecutive negative PCR results following discharge from hospitals. The interval between the two positive tests in the episodes of COVID-19 ranged from 4 to 117 days. More than one-third of the cases were healthcare workers (HCWs) and one-third of them had comorbidities. The main symptoms were cough and fever, and we noticed that males experienced more symptoms and signs of COVID-19 than females. Individuals with repeat SARS-CoV-2 positivity tend to experience milder illness during the second episode than the first episode. To confirm the reinfection of SARS-CoV-2, the results of other tests, such as viral culture and immunological assays of immunoglobulin G (IgG) and immunoglobulin M (IgM), need to be considered. Recovered COVID-19 patients should continue social distancing, using face masks, and practicing hand hygiene, especially HCWs who are more likely to be exposed to SARS-CoV-2.

Background: This study aimed to explore the psychosocial factors affecting the utilization of antenatal care (ANC) services.Methods: This was an analytical cross-sectional study carried-out in the 4 main MOH maternity hospitals in Jeddah. The study sample included 2 groups: 80 women with inadequate ANC attendance and 159 with adequate ANC attendance. We applied probability proportional to size sampling technique. The outcome of this study was ANC attendance (adequate or inadequate). Independent variables included: age, nationality, educational level, occupation, monthly income, the dependent variables included: the number of ANC visits.Results: The utilization findings of this study revealed that 88 women out of 239 women had not fully used the health services provided to them (underutilization) and the utilization rate was 66.5%. Approximately one-half of the women with inadequate ANC had birth intervals of less than 2 years. Three-quarters of them reported that they did not plan their current pregnancies, and nearly two-thirds of them had high levels of stress. Logistic regression analysis indicated that inadequate ANC attendance was predicted by past negative experiences related to ANC attendance (p=0.001) (OR=0.183 CI=0.065-0.513).Conclusions: The most significant identified barriers to utilization of ANC services were high stress, previous negative ANC experience, unplanned pregnancy, and short birth intervals. Furthermore, women who had adequate ANC visits were more likely to have planned pregnancies and be aware of available ANC services.
