Novel preventive bundle for multidrug-resistant organisms in intensive care setting; tertiary care experience.

Background: A widely-accepted standardized preventive bundle targeting multidrug-resistant organisms (MDROs) is lacking. The objective was to describe the components, implementation, compliance, and impact of a novel MDROs bundle in intensive care units (ICUs). Methods: Cohort study of surveillance activities on the components of MDROs bundle (July 2019 to June 2022) and the incidence of MDROs (April 2016 to June 2022). The implementation of MDROs bundle were preceded by ICPs-led education of the staff working in target ICUs about the importance and components of the MDROs bundle. These included the overall use of antimicrobials, appropriate environmental cleaning, appropriate contact precautions, and hand hygiene compliance. Results: During implementation, the overall use of antimicrobials was 57.8 days of therapy per 100 patient-days (44,492/76,933). It was higher in adult compared with pediatric/neonatal ICUs (p < 0.001). Appropriate environmental cleaning was 74.8% (12,409/16,582), appropriate contact precautions was 83.8% (10,467/12,497), and hand hygiene compliance was 86.9% (27,023/31,096). The three components were significantly higher in pediatric/neonatal compared with adult ICUs (p = 0.027, p < 0.001, p = 0.006, respectively). The MDROs rates per 10,000 patient-days were 71.8 before (April 2016 to June 2019) and 62.0 during (July 2019 to June 2022) the bundle implementation (858/119,565 versus 891/143,649 p = 0.002). The reduction in MDROs rates were replicated in adult (p = 0.001) but not pediatric/neonatal ICUs (p = 0.530). Conclusions: The finding of this study indicate that the implementation of the current bundle was associated with a modest decrease in MDROs rates in adult ICUs. The provided detailed definitions and methodology will facilitate its use by other healthcare facilities.

Quality of care provided to diabetic patients attending primary health care centers in National Guard in Makkah Region, Saudi Arabia.

Background: Diabetes is a costly and serious health problem that is increasing markedly. The quality of care is a major issue among diabetic patients. This study aims to assess the quality of care provided to diabetic patients using the American Diabetes Association (ADA) indicators. Methods: This was a cross-sectional study conducted using a retrospective chart review. The population was adult diabetic patients (type 2) who had attended the National Guard's primary healthcare centers, Makkah region, Saudi Arabia, from January 1, 2017, to December 31, 2018. Results: We studied 400 adult diabetic patients aged 30-97 years with a mean age of 58.25 (SD = 11.9). The length of time with diabetes ranged from 1 to 42 years with a mean of 9.66 years (SD = 7.6). Among all the primary healthcare centers (PHCs), specialized polyclinic (SPC) had the highest number of patient visits. Furthermore, the SPC had the highest number of patients with complications; the primary healthcare center with the fewest complications was Iskan-Jeddah. The results show that the control of hemoglobin A1C (HbA1C) was better in 2018 than in 2017. Conclusion: There is improved and adequate care provided to patients among the assessed primary healthcare centers in the Makkah region. Nevertheless, there remains a need for interventions to maintain comprehensive data on diabetes performance. Monitoring and proper education on diabetic care to patients are suggested to achieve better control of diabetes and delay the occurrence of complications.

Outcomes of single dose COVID-19 vaccines: Eight month follow-up of a large cohort in Saudi Arabia.

BACKGROUND: Two vaccines for COVID-19 have been approved and administered in the Kingdom of Saudi Arabia (KSA); Pfizer-BioNtech BNT162b2 and AstraZeneca-Oxford AZD1222 vaccines. The purpose of this study was to describe the real-world data on the outcome of single dose of these COVID-19 vaccines in a large cohort in KSA and to analyse demographics and co-morbidities as risk factors for infection post one-dose vaccination. METHODS: In this prospective cohort study, a total of 18,543 subjects received one dose of either of the vaccines at a vaccination centre in KSA, and were followed up for three to eight months. Data were collected from three sources; clinical data from medical records, adverse events (AEs) from a self-reporting system, and COVID-19 infection data from the national databases. The study was conducted during the pandemic restrictions on travel, mobility, and social interactions. RESULTS: The median age of participants was 33 years with an average body mass index of 27.3. The majority were males (60.1%). Results showed that 92.17% of the subjects had no COVID-19 infection post-vaccination as infection post-vaccination was documented for 1452 (7.83%). Diabetes mellitus 03), organ transplantation (p = 0.02), and obesity (p < 0.01) were associated with infection post-vaccination. Unlike vaccine type, being Saudi, male, or obese was associated with the occurrence breakthrough infections more than other parameters. AEs included injection site pain, fatigue, fever, myalgia, headache and was reported by 5.8% of the subjects. CONCLUSION: Single dose COVID-19 vaccines showed a protection rate of 92.17% up to eight months follow-up in this cohort. This rate in AZD1222 was higher than what have been previously reported in effectiveness studies and clinical trials. Obese, male, and Saudi were at higher risk of contracting the infection post-vaccination, Saudi and male might have more social interaction with the public when mobility and social interactions were limited during the pandemic. Side effects and AEs were within what has been reported in clinical trials.

Risk of COVID-19 in healthcare workers working in intensive care setting.

BACKGROUND: The higher risk of COVID-19 in health care workers (HCWs) is well-known. However, the risk within HCWs is not fully understood. The objective was to compare the COVID-19 risk in intensive care unit (ICU) vs non-ICU locations. METHODS: A prospective surveillance study was conducted among HCWs at a large tertiary care facility in Riyadh between March 1st to November 30th, 2020. HCWs included both clinical (provide direct patient care) and nonclinical positions (do not provide direct patient care). RESULTS: A total 1,594 HCWs with COVID-19 were included; 103 (6.5%) working in ICU and 1,491 (93.5%) working in non-ICU locations. Compared with non-ICU locations, ICU had more nurses (54.4% vs 22.1%, P < .001) and less support staff (2.9% vs 53.1%, P < .001). COVID-19 infection was similar in ICU and non-ICU locations (9.0% vs 9.8%, P = .374). However, it was significantly higher in ICU nurses (12.3% vs 6.5%, P < .001). Support staff had higher risk than other HCWs, irrespective of ICU working status (15.1% vs 7.2%, P < 0.001). The crude relative risk of COVID-19 in ICU vs non-ICU locations was 0.92, 95% confidence interval ( was 0.76-1.11 (P = .374). However, relative risk adjusted for professional category was significantly increased to 1.23, 95% confidence interval 1.01-1.50 (P = .036). CONCLUSIONS: ICU had a significantly higher risk of COVID-19 infection only after adjusting for the distribution and risk of different professional categories. The latter is probably determined by both exposure level and protection practices. The finding underscores the importance of strict implementation of preventive measures among all HCWs, including those performing nonclinical services.

Post-vaccination SARS-CoV-2 infection among healthcare workers in tertiary care hospitals in Saudi Arabia: A case series.

Healthcare workers have been categorized among the priority groups for COVID-19 vaccination. However, post-vaccination infections have been identified. This study was conducted to investigate SARS-CoV-2 infection among healthcare workers (HCWs) who received the COVID-19 vaccine. A case series in a multicenter healthcare system in Saudi Arabia was created from HCWs who had (PCR-RT) confirmed SARS-CoV-2 infection after at least one dose of Pfizer-BioNTech vaccination. A total of 20 healthcare workers (HCWs) have been included. The majority (70.0%) were males and the average age was 39.4 ± 10.1 years. They included physicians (55.0%), nurses (25.0%) and other HCWs (20.0%). Eighteen (90%) HCWs had infection after the first dose; 47.1% within the first week, 41.2% within the second week, and 11.8% within the third week. Only two HCWs (10.0%) had infection one week after the second dose. The majority (63.2%) had mild (52.6%) or moderate (10.3%) disease with no severe disease or hospitalization. The majority of post-vaccination COVID-19 infections among HCWs occurred before the full protection of the vaccine is gained. Suspicion of COVID-19 infection should be considered even with a history of COVID-19 vaccination. Recently vaccinated HCWs should be advised to fully comply with all recommended precautions to prevent COVID-19 transmission.

The Epidemiology of Invasive Meningococcal Disease in the Kingdom of Saudi Arabia: A Narrative Review with Updated Analysis.

Reducing invasive meningococcal disease (IMD) through MenACWY immunization is a critical healthcare strategy in the Kingdom of Saudi Arabia (KSA). Robust IMD surveillance is essential to help assess the need for additional immunization initiatives in target populations. This is particularly important in KSA, where mass gatherings accompanying Hajj/Umrah pilgrimages have been associated with IMD outbreaks within the local KSA population, and subsequent intercontinental spread via returning pilgrims. This narrative review of the published literature describes the changing epidemiology of IMD in KSA to provide a perspective on the impact of current immunization strategies and potential gaps. As recent published surveillance data are lacking, we also evaluated publicly reported data from the KSA Ministry of Health (MoH) for 2012-2019 to inform more recent IMD trends. Between 1995 and 2011, national surveillance data indicate that 1103 IMD cases were reported in KSA: 60% in 2000-2001, involving two (mainly MenW) outbreaks involving KSA citizens/residents and pilgrims focused in Mecca and Medina. Across 2002-2011, 184 cases of IMD were reported, with a higher proportion occurring in KSA citizens/residents, and with less focus within pilgrimage centers than apparent in previous years. Our analysis of MoH data found that, between 2012 and 2019, 44 IMD cases were reported, all in KSA citizens/residents, and chiefly in children or infants. No pilgrimage-associated outbreaks have occurred since 2001. Serogroup data were available for 62.5% of all cases for 2002-2011; MenW (40.0%), MenA (35.7%), and MenB (16.5%). Serogroup data for 2012-2019 remain incompletely reported, and the existing surveillance system could be improved, as some element of underestimation/underreporting of IMD may exist. While existing MenACWY immunization strategies for KSA citizens/residents and visiting pilgrims have been successful in reducing IMD due to specific serogroups, disease due to MenB remains a potential risk, and additional immunization strategies should be considered.

Clinical characteristics and outcomes of community-acquired pneumonia in western Saudi Arabia: A four-year retrospective analysis of medical records.

BACKGROUND: Community-acquired pneumonia (CAP) is a significant cause of morbidity and mortality, especially for the elderly and people who suffer from chronic conditions. This study was conducted to assess the clinical and microbiological characteristics and disease outcomes associated with the occurrence of CAP. METHODS: This retrospective chart review was conducted at King Abdulaziz Medical City, Jeddah, Saudi Arabia. Cases with documented clinical diagnosis of CAP during the period from 2016 to 2019 were included. Data were collected on demographic, clinical, and microbiological characteristics, used antimicrobials and patients' outcomes, including length of hospital stay, intensive care unit admission, and mortality. Multivariate regression analysis was performed to identify risk factors for increased length of hospital stay. RESULTS: A total of two hundred and eighteen CAP episodes were identified. Patients had a median age of 64.5 years, and 54.1% were males. Microbiological diagnosis was established in 33 patients (15.1%). Admission to ICU and diagnosis of a neurological disease were significantly associated with longer hospital stay (>7 days). An average of 2.7 antimicrobials were used per patient, and the most common antibiotics used were Piperacillin/Tazobactam (46.3%), Doxycycline (44%), then Ceftriaxone (42.7%). Four patients (1.8%) died during hospital stay. CONCLUSIONS: This retrospective analysis of CAP cases identified a lack of microbiological diagnosis and increased burden associated with disease severity and the need for hospitalization. The ability to identify CAP at an earlier stage will be a cornerstone to mitigate its impact on the healthcare system and ICU units.

Epidemiological characteristics of cervical cancer in a tertiary care hospital, western Saudi Arabia: A retrospective record-based analysis from 2002-2018.

OBJECTIVES: To investigate the epidemiological characteristics of cervical cancer cases reported at a tertiary care teaching hospital in western Saudi Arabia. METHODS: A retrospective chart review was conducted on medical records of patients diagnosed with cervical cancer at King Abdulaziz Medical City, Jeddah, Saudi Arabia. Data were collected on demographic characteristics, histological types and stage, treatment modalities, and disease outcomes. RESULTS: Cervical cancer was diagnosed among 89 patients from 2002 to 2018. History of pap smear was reported among 31 cases (34.8%). Squamous cell carcinoma was the most common reported histopathological subtype. Almost one third (29.2%) of the patients were at stage III or IV at the time of diagnosis. The most frequent treatment regimen was combined radio/chemotherapy. Kaplan-Meier analysis showed an overall survival rate of 81.5%. CONCLUSION: The lack of an effective screening program for cervical cancer increases the likelihood of a late diagnosis and higher rates of complications and mortality. Public health programs should focus on cancer screening, screening, and reporting HPV infections, and supporting HPV vaccination activities.

The prevalence of comorbidities among adult people diagnosed with HIV infection in a tertiary care hospital in western Saudi Arabia.

BACKGROUND: The life expectancy of people living with HIV is markedly increasing with the introduction of effective antiretroviral medications. However, these patients face an increased risk of developing multi-morbidities-especially with advanced age. This study was conducted to assess the prevalence of and risk factors associated with the occurrence of chronic comorbidities among patients diagnosed with HIV infection. METHODS: A retrospective chart review was conducted on the medical records of patients with HIV diagnoses from 2000 to 2018. Data were collected on age, sex, date of diagnosis, associated co-morbidities, antiretroviral medications (ART) and status at time of data collection (alive or deceased). Only adult patients 18 years or above were studied. RESULTS: A total of 130 confirmed HIV cases were included. Patient ages ranged from 23 to 86 years old (mean±SD 50.1±12.6). Almost half of the patients (48.5%) had at least one associated comorbidity. The most common chronic comorbidity was diabetes mellitus (15.4%), followed by dyslipidemia (10.8%), hypertension (10.8%) and lymphoma (10.0%). Comorbidity proportions increased with advanced patient age (p=0.047). Three or more comorbidities were reported in 40.7% of patients aged 60 years old or above. Using logistic regression analysis, only patients aged 50 years old or above were more likely to have at least one comorbidity (OR=7.59, 95%CI=2.25, 25.61). CONCLUSIONS: The burden of chronic comorbidities among people diagnosed with HIV is high, especially among older age individuals, with an increasing number of comorbidities per patient. Proper counseling for HIV patients is highly recommended-not only for prevention of other infectious diseases (e.g., vaccination) but also for lifestyle modification and self-management for those with chronic conditions.

Magnitude of behavioral deficits varies with job-related chlorpyrifos exposure levels among Egyptian pesticide workers.

Chronic occupational exposure to organophosphorus pesticides (OPs) is consistently associated with deficits on behavioral tests when compared to unexposed comparison groups. However, a dose-response relationship has yet to be established, leading some to doubt an association between occupational OP exposure and behavioral deficits. Pesticide application teams in Egypt who are primarily exposed to one OP, chlorpyrifos (CPF), were recruited into a field assessment. Trail Making A and the more challenging Trail Making B tests were administered to 54 engineers (who supervise the pesticide application process, usually from the side of the field), 59 technicians (who guide the pesticide applicators in the field), 31 applicators (who mix and apply pesticides using knapsack sprayers), and 150 controls (who did not work in the fields) at two different times during the OP application season as well as immediately after applications had ended and 1.5 months later. All participants were males since only males work on pesticide application teams in Egypt. Urinary levels of 3,5,6-trichloro-2-pyridinol (TCPy), a specific metabolite of CPF, confirmed the pattern of lower to higher CPF exposures from engineers to technicians to applicators, and these were all greater than urinary metabolite levels in controls. A consistent relationship between job title and performance speed on the behavioral task was observed: Controls had the best (fastest) performance on Trail Making A and B tests throughout the application season, and applicators had significantly slower performance than engineers on Trail Making A (p = 0.015) and B (p = 0.003). However, individual urinary TCPy, blood acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) levels did not predict individual performance. This study identifies a dose-related effect based on job title, which serves as a surrogate for chronic exposure in that differing job titles exhibit varying group exposure levels. The results establish that chronic occupational exposure to chlorpyrifos is neurotoxic and suggest that the classic biomarkers of recent CPF exposure are not predictive of chronic exposure effects.

Association between type 2 diabetes mellitus and Helicobacter pylori infection among Saudi patients attending National Guard Primary Health Care Centers in the Western Region, 2018.

BACKGROUND: Reports on Helicobacter pylori infection in diabetics are inconsistent and contradictory. This study attempted to identify the possible association between type 2 diabetes and H. pylori infection. MATERIALS AND METHODS: Following a cross-sectional design, participants were recruited from four National Guard Primary Health Care Centers in Jeddah City, Saudi Arabia. The study was conducted from December 2017 to November 2018. All participants underwent hemoglobin A1C (HbA1c) assessment and stool antigen test for H. pylori. RESULTS: A total of 212 type 2 diabetic patients aged 40 years or more, and 209 age-matched nondiabetic subjects were included in the study. About one-quarter of the diabetics and nondiabetics were positive for H. pylori (26.9% and 26.3%, respectively). There was no significant difference. The prevalence of H. pylori did not differ significantly in the type 2 diabetics, with regard to their age groups, gender, smoking status, body mass index, chronic diseases, their HbA1c level, duration of diabetes, or received type of therapy. The prevalence of H. pylori was significantly higher in overweight and obese nondiabetic subjects (P = 0.013). Obese participants in both groups had the highest prevalence of infection (57.9% and 54.5%, respectively, P = 0.038). CONCLUSION: About one-quarter of type 2 diabetics and nondiabetics in Jeddah City have H. pylori infection. There is no association between diabetes and H. pylori infection. H. pylori was significantly higher in patients with a high body mass index.

Illness anxiety disorder and perception of disease and distress among medical students in western Saudi Arabia.

OBJECTIVES: To estimate and assess the prevalence and predictors of illness anxiety disorder among Saudi medical students in western Saudi Arabia. Methods: A cross-sectional study was conducted from November 2017 to March 2018 at King Saud bin Abdulaziz University for Health Sciences, Jeddah, Saudi Arabia. A self-administered questionnaire was applied. The questionnaire is composed of demographic data, the short version of the Health Anxiety Inventory (SHAI), the Medical Student's Disease (MSD) perception and distress scale and history of a visit to a physician in the past 6 months. Results: Two hundred and seventy-one Saudi medical students participated; 71% were males and 53% were less than 22 years old. The participants represented all academic years, with 54% in their 4th, 5th, and 6th years. Illness anxiety disorder was identified in 17% of the participants. Younger students and those with a history of a physician's visit within the past 6 months were more likely to have illness anxiety disorder (OR=2.31, 95%  CI= 1.16, 4.60; OR=2.46, 95% CI=1.25, 4.84). Conclusions: The prevalence of illness anxiety disorder among Saudi medical students is comparable to similar recent studies. Student counseling programs highlighting coping techniques, especially during the early study years, should be implemented.

Treatment patterns, resource utilization, and outcomes among hospitalized patients with methicillin-resistant Staphylococcus aureus complicated skin and soft tissue infections in Lebanon and Saudi Arabia.

OBJECTIVES: To describe treatment patterns and medical resource use for methicillin-resistant Staphylococcus aureus (MRSA) complicated skin and soft tissue infections (cSSTI) in Saudi Arabia and Lebanon in terms of drug selection against the infecting pathogen as well as hospital resource utilization and clinical outcomes among patients with these infections. METHODS: This retrospective chart review study evaluated 2011-2012 data from five hospitals in Saudi Arabia and Lebanon. Patients were included if they had been discharged with a diagnosis of MRSA cSSTI, which was culture-proven or suspected based on clinical criteria. Hospital data were abstracted for a random sample of patients with each infection type to capture demographics, treatment patterns, hospital resource utilization, and clinical outcomes. Statistical analysis was descriptive. RESULTS: Data were abstracted from medical records of 87 patients with MRSA cSSTI; mean age 52.4±25.9 years and 61% male. Only 64% of patients received an MRSA active initial therapy, with 56% of first-line regimens containing older beta-lactams. The mean total length of stay was 26.3 days, with the majority (19.1 days) spent in general wards. Surgical procedures included incision and drainage (22% of patients), debridement (14%), and amputation (5%). Mechanical ventilation was required by 9% of patients, with a mean duration of 18 days per patient. Hemodialysis was required by four patients (5%), two of whom were reported to have moderate to severe renal disease on admission, for a mean of 5.5 days. Inpatient mortality was 8%. Thirty-nine percent were prescribed at least one antibiotic at discharge, with the most commonly prescribed discharge antibiotics being clindamycin (44%), ciprofloxacin (18%), trimethoprim/sulfamethoxazole (12%), and linezolid (9%). CONCLUSION: This Middle Eastern real-world study of resource use and treatment patterns in MRSA cSSTI indicates that management of this condition could be further optimized in terms of drug selection and resource utilization.

Burden and treatment patterns of invasive fungal infections in hospitalized patients in the Middle East: real-world data from Saudi Arabia and Lebanon.

OBJECTIVES: The objective of this study was to document the burden and treatment patterns associated with invasive fungal infections (IFIs) due to Candida and Aspergillus species in Saudi Arabia and Lebanon. METHODS: A retrospective chart review study was conducted using data recorded from 2011 to 2012 from hospitals in Saudi Arabia and Lebanon. Patients were included if they had been discharged with a diagnosis of IFI due to Candida or Aspergillus, which was culture proven or suspected based on clinical criteria. Hospital data were abstracted for a random sample of patients to capture demographics, treatment patterns, hospital resource utilization, and clinical outcomes. Descriptive results were reported. RESULTS: Five hospitals participated and provided data on 102 patients with IFI (51 from Lebanon and 51 from Saudi Arabia). The mean age of the patients was 55 years, and 55% were males. Comorbidities included diabetes (41%), coronary artery disease (24%), leukemia (19%), moderate-to-severe renal disease (16%), congestive heart failure (15%), and chronic obstructive pulmonary disease (15%). Twenty percent of patients received corticosteroids prior to admission and 26% had received chemotherapy in the past 90 days. Inpatient mortality was 42%, and the mean hospital length of stay was 32.4±28.6 days. Fifty-five percent of patients required intensive care unit admission (17.2±14.1 days), 37% required mechanical ventilation (13.7±13.2 days), and 11% required dialysis (14.6±14.2 days). The most commonly used first-line antifungal was fluconazole. CONCLUSION: Patients with IFI in Saudi Arabia and Lebanon frequently have multiple medical comorbidities and may not have traditionally observed IFI risk factors. Efforts to increase use of rapid diagnostic tests and appropriate antifungal treatments may impact the substantial mortality and high length of stay observed in these patients.

Patients' attitudes towards the participation of medical students in clinical examination and care in Western Saudi Arabia.

BACKGROUND AND OBJECTIVES: Patients are essential for the acquisition and development of medical students clinical skills for their tasks. The study aimed to identify factors that influence patients' attitudes towards the involvement of medical students in clinical examination and care in Western Saudi Arabia. METHODS: A cross-sectional study using self-administered questionnaire was conducted among Saudi and non-Saudi patients at two university hospitals in Jeddah, Western Saudi Arabia. Information sought included demographic characteristics (age, gender, educational level, job, income, and marital status); patients' attitude and comfort level towards different types of students' involvement; factors influencing patients' cooperation with medical students (students' level of training, manner, skills, and attire. All these were assessed on a five-point Likert scale. Data was entered and analyzed using SPSS v 19. RESULTS: Four hundred and seventeen adult patients participated. Fifty-one percent indicated a positive attitude towards involving medical students in clinical examination and care. Female and young patients (<45 years old) were more likely to be negative in their attitude and be less comfortable towards involving medical students in their care. The highest overall mean comfort score was with medical students taking history followed by observations and less invasive examination. Patients' mean confidence scores regarding students' attire were the highest for female traditional attire and for scrub suit for males. CONCLUSION: Of the influential factors that could affect patients' willingness to cooperate with medical students, clinical skills followed by manner and level of training ranked first. Ensuring that students mastered specific procedures before coming into direct contact with patients using patient simulators, for example, would improve patients' acceptance of student participation.

Impact of rehabilitation programs on dependency and functional performance of patients with major lower limb amputations. A retrospective chart review in western Saudi Arabia.

OBJECTIVES: To determine pattern and impact of physical rehabilitation on dependency and functional performance of patients.  METHODS: This retrospective chart review was carried out between July and August 2012 at King Abdulaziz Medical City, Jeddah, Saudi Arabia. Data were collected using demographic, clinical, and dependency assessment checklists.  RESULTS: Patients who underwent major lower limb amputations between January 2007 and April 2012 (n=121) were included in the study. There were 84 (69.4%) male and 37 (30.6%) female patients with a mean ± standard deviation of 63.3  ± 17.4 years old. Diabetes mellitus was the most frequent cause in 63.6% of patients. Only one-third of the amputees (32.2%) have records of completion of their rehabilitation programs, although 20.7% of them completed the less than 50% of the scheduled rehabilitation sessions, 17.2% attended between 50% and 80%, and the remaining 62.1% attended more than 80% of the scheduled sessions. Muscle power scores in each side of the upper and lower limbs were significantly better following rehabilitation (p less than 0.0001). Basic functions of mobility and transfer have also significantly improved (p less than 0.05).  CONCLUSIONS: Overall dependency and functional performance were significantly better following implementation of the physical rehabilitation programs. A multidisciplinary team approach is mandatory to improve compliance of patients toward the rehabilitation programs.

Longitudinal assessment of occupational exposures to the organophosphorous insecticides chlorpyrifos and profenofos in Egyptian cotton field workers.

Chlorpyrifos (CPF) and profenofos (PFF) are organophosphorus (OP) insecticides that are applied seasonally in Egypt to cotton fields. Urinary trichloro-2-pyridinol (TCPy), a specific CPF metabolite, and 4-bromo-2-chlorophenol (BCP), a specific PFF metabolite, are biomarkers of exposure, while inhibition of blood butyrylcholinesterase (BChE) and acetylcholinesterase (AChE) activities are effect biomarkers that may be associated with neurotoxicity. Urinary TCPy and BCP and blood BChE and AChE activities were measured in 37 adult Egyptian Ministry of Agriculture workers during and after 9-17 consecutive days of CPF application followed by an application of PFF (9-11 days), and a second CPF application (5 days) in 2008. During the OP applications, urinary TCPy and BCP levels were significantly higher than baseline levels, remained elevated following the application periods, and were associated with an exposure related inhibition of blood BChE and AChE. Analysis of blood AChE levels before and after the PFF application period suggests that individual workers with peak BCP levels greater than 1000 µg/g creatinine exhibited further inhibition of blood AChE with PFF application, demonstrating that PFF exposure had a negative impact on AChE activity in this highly exposed worker population. While large interindividual differences in exposure were observed throughout this longitudinal study (peak urinary BCP and peak TCPy levels for individuals ranging from 13.4 to 8052 and 16.4 to 30,107 µg/g creatinine, respectively), these urinary biomarkers were highly correlated within workers (r=0.75, p<0.001). This suggests that the relative exposures to CPF and PFF were highly correlated for a given worker. The variable exposures between job classification and work site suggest that job title and work location should not be used as the sole basis for categorizing OP exposures when assessing neurobehavioral and other health outcomes in Egyptian cotton field workers. Together, these findings will be important in educating the Egyptian insecticide application workers in order to encourage the development and implementation of work practices and personal protective equipment to reduce their exposure to CPF and PFF.

Predictors and outcomes of Candida bloodstream infection: eight-year surveillance, western Saudi Arabia.

OBJECTIVES: To assess the epidemiological pattern of Candida bloodstream infection (BSI) over an 8-year period (2002-2009) in King Abdulaziz Medical City, western Saudi Arabia. METHOD: A retrospective chart review was performed. RESULTS: A total of 258 BSI were identified in 134 males (53.2%) and 118 females (46.8%). There were 86 (34.1%) cases of Candida albicans and 166 (65.9%) non-albicans Candida species. Malignancy was independently associated with the development of candidemia by non-albicans Candida species (odds ratio 3.24, 95% confidence interval 1.25-8.41). Fluconazole in vitro susceptibility was 38.5% for C. albicans and 52.5% for other Candida species. The overall, crude 12-month mortality rate was 50% for C. albicans and 57.8% for non-albicans Candida species. CONCLUSIONS: The antifungal resistance coinciding with a change in the epidemiologic pattern of candidemia identified in this study is alarming and urges the need for a review of empiric antifungal therapy and potential contributing environmental factors.
