Metabolic syndrome and associated factors among psychiatric patients in Jimma University Specialized Hospital,South West Ethiopia

Background

Metabolic syndrome is a multisystem disorder which coined to describe the recognized clustering of metabolic and cardiovascular abnormalities including obesity, hypertension, dyslipidemia, and abnormalities of glucose homeostasis.

Progression of clinical tuberculosis is associated with a Th2 immune response signature in combination with elevated levels of SOCS3

In this study, we explored the local cytokine/chemokine profiles in patients with active pulmonary or pleural tuberculosis (TB) using multiplex protein analysis of bronchoalveolar lavage and pleural fluid samples. Despite increased pro-inflammation compared to the uninfected controls; there was no up-regulation of IFN-γ or the T cell chemoattractant CCL5 in the lung of patients with pulmonary TB. Instead, elevated levels of IL-4 and CCL4 were associated with high mycobacteria-specific IgG titres as well as SOCS3 (suppressors of cytokine signaling) mRNA and progression of moderate-to-severe disease. Contrary, IL-4, CCL4 and SOCS3 remained low in patients with extrapulmonary pleural TB, while IFN-γ, CCL5 and SOCS1 were up-regulated. Both SOCS molecules were induced in human macrophages infected with Mycobacterium tuberculosis in vitro. The Th2 immune response signature found in patients with progressive pulmonary TB could result from inappropriate cytokine/chemokine responses and excessive SOCS3 expression that may represent potential targets for clinical TB management.     

A Retrospective Analysis on Cervical Spine Magnetic Resonance Imaging Findings in Patients with Neck Pain in a Tertiary Hospital,Addis Ababa,Ethiopia

BackgroundNeck pain is a common health problem throughout the world causing significant individual disability and economic burden on health care facility. Many factors are mentioned as a cause or association in relation to neck pain, of which degenerative and posttraumatic cause are the main ones. The aim of this study is to assess cervical spine Magnetic Resonance Imaging (MRI) patterns in patients presented with neck pain.MethodsA retrospective analysis of 160 patients who had cervical spine Magnetic Resonance Imaging (MRI) for evaluation of a neck pain was done. The study was conducted between February to August 2018 at Tikur Anbessa Specialized Hospital. The patients'' clinical history and magnetic resonance imaging reports were reviewed from their medical records. All patients who have cervical spine Magnetic Resonance Imaging (MRI) for a neck pain were included in the study. Those patients with acute traumatic neck pain were excluded.ResultsFrom a total of 160 patients, 71(44.4%) were males and 89(55.6%) were females. Degenerative cervical spine findings such as intervertebral disc degenerations were seen in 127(79.4%) patients. Non-degenerative imaging findings such as neoplasm and infection were seen in 10(6.3%) patients only. The MRI was normal in 23(14.4%) of them.ConclusionThe most common cause of neck pain from this study is degenerative changes of the cervical spine, which was predominant in the older age groups. Non-degenerative causes such as neoplasm and infection were less common findings.     

FcRn binding properties of an abnormal truncated analbuminemic albumin variant

Background:The major histocompatibility class I-related neonatal Fc receptor, FcRn, salvages both IgG and albumin from degradation and thus contributes to maintain high serum levels of these proteins. Analbuminemia is a rare autosomal recessive disorder characterized by clinically observed allelic albumin variants that are absent or found in very low concentrations in the blood circulation. Such variants may have altered FcRn binding properties that affect their half-life, biodistribution and thereby transport ability.Methods:We established an easy cloning, expression and purification strategy to obtain recombinant GST-tagged human serum albumin (HSA) variants for evaluation of pH dependent FcRn binding properties using an enzyme-linked immunosorbent assay (ELISA) and a real time surface plasmon resonance (SPR) biosensor system.Results:The strategy yielded purified GST-tagged albumin variants. A recombinant truncated HSA variant similar to a clinically observed splice mutant denoted Bartin, here abrogated HSA^Bartin, showed no detectable pH dependent FcRn binding compared to a fully functional albumin wild type variant, HSA^Wt, and a truncated HSA variant consisting of only the carboxy terminal domain III (HSA^DIII).Conclusions:The approach described can be used to rapidly screen clinically observed truncated or otherwise mutant or modified HSA variants regarding their pH dependent FcRn binding properties. Here, we demonstrate that a recombinant truncated HSA variant, HSA^Bartin, does not interact with FcRn, which gives a molecular explanation for the low serum levels. In addition, DIII of HSA alone was shown to retain its FcRn binding property.     

A prognostic model for survival in chronic lymphocytic leukaemia based on p53 expression

As the abnormal expression of p53 protein is prognostically significant in some human cancers, its significance in patients with B-cell chronic lymphocytic leukaemia (CLL) was assessed. Two investigators evaluated the percentage of bone marrow mononuclear cells that stained for p53, using biopsies stained with anti-p53 monoclonal antibody (DO-7), and graded the degree of staining (0, +, ++, +++). Samples from a cohort of 90 patients with CLL were studied (median age 60 years, range 30-89 years; 57 patients were (63%) previously untreated, 22 patients (24%) had received one or two prior regimens, 11 patients had received (12%) three to seven regimens. The overall percentage of cells positive for p53 staining was a median of 43 (range 1-88). No investigator effect was detected either in overall percentage cells rated p53 positive or on the degree of staining (Pearson's correlation coefficient 0.980, P-value < 0.001). A Cox proportional hazards model showed that the percentage of ++ and +++ p53-positive cells correlated with various prognostic factors in CLL (P < 0.0001). A multivariate model incorporating prior therapy, Rai stage, beta2 microglobulin (beta2M) and p53 expression showed that only the percentage of p53-positive cells and beta2M were predictive of survival, and enabled the development of a highly predictive model of survival based on these two parameters.     

Cetuximab and irinotecan interact synergistically to inhibit the growth of orthotopic anaplastic thyroid carcinoma xenografts in nude mice.

PURPOSE: Anaplastic thyroid carcinoma (ATC) remains one of the most lethal known human cancers. Targeted molecular therapy with cetuximab, a monoclonal antibody against epidermal growth factor receptor, offers new treatment potentials for patient with ATC. Cetuximab has also been reported to have synergistic effects when combined with irinotecan, a topoisomerase inhibitor. Therefore, we hypothesized that cetuximab and irinotecan would be effective in inhibiting the growth and progression of ATC in a murine orthotopic model. EXPERIMENTAL DESIGN: The in vitro antiproliferative effects of cetuximab and irinotecan on ATC cell line ARO were examined. We also studied the in vivo effects of cetuximab and irinotecan on the growth, invasion, and metastasis of orthotopic ATC tumors in nude mice. The in vivo antitumor efficacy of cetuximab/irinotecan combination was also compared with that of doxorubicin. RESULTS: Cetuximab alone did not show any antiproliferative or proapoptotic effect on this cell line. However, when combined with irinotecan, cetuximab potentiated the in vitro antiproliferative and proapoptotic effect of irinotecan. Cetuximab, irinotecan, and cetuximab/irinotecan combination resulted in 77%, 79%, and 93% in vivo inhibition of tumor growth, respectively. Incidences of lymph node metastasis, laryngeal invasion, and tumor microvessel density were also significantly decreased in these treatment groups. Furthermore, the cetuximab/irinotecan combination was significantly more effective than doxorubicin in inhibiting the growth of orthotopic ATC xenografts. CONCLUSIONS: Combination therapy with cetuximab/irinotecan inhibits the growth and progression of orthotopic ATC xenografts in nude mice. Given the lack of curative options for patients with ATC, combination therapy with cetuximab and irinotecan treatment warrants further study.     

Franchising Reproductive Health Services

Objectives. Networks of franchised health establishments, providing a standardized set of services, are being implemented in developing countries. This article examines associations between franchise membership and family planning and reproductive health outcomes for both the member provider and the client.
Methods. Regression models are fitted examining associations between franchise membership and family planning and reproductive health outcomes at the service provider and client levels in three settings.
Results. Franchising has a positive association with both general and family planning client volumes, and the number of family planning brands available. Similar associations with franchise membership are not found for reproductive health service outcomes. In some settings, client satisfaction is higher at franchised than other types of health establishments, although the association between franchise membership and client outcomes varies across the settings.
Conclusions. Franchise membership has apparent benefits for both the provider and the client, providing an opportunity to expand access to reproductive health services, although greater attention is needed to shift the focus from family planning to a broader reproductive health context.     

Comparison of molecular abnormalities in bronchial brushings and tumor touch preparations

BACKGROUND: Preneoplastic lung lesions and early-stage lung carcinomas are associated with molecular abnormalities. The authors performed a pilot study to evaluate the use of DNA fluorescence in situ hybridization (FISH) probes to ascertain whether these biomarkers can predict nonsmall cell lung carcinoma (NSCLC). METHODS: Fourteen bronchial brushings ipsilateral to the tumor (BB/Ts), tumor touch imprints, and touch imprints of the bronchus adjacent to the tumor obtained from 15 patients with early-stage NSCLC were analyzed. The LAVysion multicolor probe set consisting of probes to 5p15, 6, 7p12, and 8q2 and the in-house probes 3p22.1 and 10q22 was used. Using the LAVysion multicolor probe set, 25 epithelial cells were counted and considered positive if > 5 cells were abnormal. Using 3p22.1 and 10q22, > or = 100 nuclei per slide were scored. The results were tabulated as the percentage of cells with deletions compared with the centromeric probes 3 and 10. Greater than 2% of the deletions were positive for 3p22.1 and 10q22. Bronchial washings from patients without lung tumors were used as controls. RESULTS: The BB/Ts were negative for malignant cells by cytologic evaluation and the LAVysion probe set; however, the combined in-house probes for 3p22.1 and 10q22 tested on BB/Ts predicted cancer in 100% of cancer patients. FISH positivity in the lung cancers was 100% for 3p22.1 deletions, 79% for 10q22 deletions, and 57% for LAVysion probes. When compared with the bronchial epithelium, tumor cells showed a 3.7-fold excess of 3p22.1 deletions, a 2-fold excess of 10q22 deletions, and a 12.6-fold excess of abnormal cells. CONCLUSIONS: The current study indicated that detection of molecular abnormalities in bronchial epithelial cells via FISH was very useful in identifying patients at high risk for developing lung carcinoma. The molecular abnormalities identified in the BB/Ts were detected at elevated levels in the tumor specimens.     

Epidemiology and outcomes of serious influenza-related infections in the cancer population

BACKGROUND: Although patients with cancer generally respond favorably to vaccination, they may not receive annual influenza vaccinations. The current population-based study described the epidemiology and outcomes of potentially preventable, serious influenza-related infections in patients with cancer. METHODS: From the Nationwide Inpatient Sample, the authors created a subsample that included discharges with any International Classification of Diseases, ninth revision, diagnosis code for cancer and principal diagnosis code for influenza, bronchopneumonia, or pneumonia caused by an unspecified organism. From the latter two diagnosis codes, the authors estimated excess cases during the influenza season for each year and stratum, then selected a random sample from fall and winter discharges. Subset analyses included weighted sample means, frequencies, and analysis of variance values. The authors converted charges to costs using cost-to-charge ratios and inflated these to 2003 U.S. dollars. Hospitalization and mortality rates were calculated using 5-year cancer prevalence estimates. RESULTS: The estimated mean annual hospital discharges of patients with cancer with potentially preventable, serious influenza-related infections numbered 16,000. The average length and cost per stay were 6 days and > USD 6300, respectively. Approximately 9% of patients died in the hospital and 31% needed further skilled care. The estimated age-specific rates for hospitalization and death per 100,000 in the prevalent cancer population were 219 and 17.4, respectively, for patients age < 65 years and 623 and 59.4, respectively, for those age > or = 65 years. Hospitalization costs averaged USD 1300 more for patients age < 65 years. CONCLUSIONS: Death from influenza-related infections occurred in an estimated 9% of patients with cancer hospitalized for such. Using recommended vaccination schedules for patients with cancer and their contacts reduced hospitalizations, treatment delays, and deaths in this highly susceptible population.     

Underweight is independently associated with mortality in post-operative and non-operative patients admitted to the intensive care unit: a retrospective study

BACKGROUND: Low and high body mass index (BMI) have been recently shown to be associated with increased and decreased mortality after ICU admission, respectively. The objective of this study was to determine the impact of BMI on mortality and length of stay in patients admitted to the intensive care unit (ICU). METHODS: In this retrospective cohort study, the Acute Physiology and Chronic Health Evaluation (APACHE) III database of patients admitted to the ICUs of a tertiary academic medical center, from January 1997 to September 2002, was crossed with a Hospital Rule-based Systems database to obtain the height and weight of the patients on admission to the ICU. The cohort was divided in post-operative and non-operative groups. We created the following five subgroups based on the BMI: <18.5, 18.5 to 24.9, 25 to 29.9, 30.0 to 39.9, >/= 40.0 Kg/m2. A multiple logistic regression analysis was used to determine the independent impact of BMI on hospital mortality. The ICU length of stay ratio was defined as the ratio of the observed to the predicted LOS. P-value < 0.05 was considered significant. The 95% confidence interval (CI) was calculated for the odds ratio (OR). RESULTS: BMI was available in 19,669 of the 21,790 patients in the APACHE III database; 11,215 (57%) of the patients were admitted post-operatively. BMI < 18.5 was associated with increased mortality in both post-operative (OR = 2.14, 95% CI, 1.39 to 3.28) and non-operative (OR = 1.51, 95% CI, 1.13 to 2.01) patients. Post-operative patients with a BMI between 30.0 to 39.9 had a lower mortality rate (OR = 0.68, 95% CI, 0.49 to 0.94). Post-operative patients with BMI <18.5 or BMI >/= 40 had an ICU length of stay ratio significantly higher than patients with BMI between 18.5 to 24.9. The addition of BMI < 18.5 did not improve significantly the accuracy of our prognostic model in predicting hospital mortality. CONCLUSIONS: Low BMI is associated with higher mortality in both post- and non-operative patients admitted to the ICU. LOS is increased in post-operative patients with low and high BMIs.
