Knowledge and Practice of Self-Care Management of Persons with Type II Diabetes At a Health Centre in East Trinidad

Aim: The study was to determine the levels of knowledge and practice of self-care management of patients with type11 diabetes at Manzanilla Clinic in East Trinidad. Methods: A quantitative descriptive study was undertaken, using all attendees to the health center on a 5-week period. A researchers'-structured Likert-like questionnaire was developed and pretested for the study. Although 88 attendees were targeted, only 66 consented and therefore were recruited for the study. Data was analyzed with SPSS programme version 20. It was presented as frequencies in tables. Result: Results show that the clinic attendees are mostly literate, of Hindi and Christian faiths, with moderate to high level of knowledge on glucose monitoring test, medication compliance, and foot care. This knowledge is however not commensurate with the proficiency of self-care among the participants. Discussion: The result was discussed in relation to literature. The implication of the result was also presented particularly on the focus of health education strategies. Conclusion: Although the respondents showed sufficient knowledge (moderate to high levels), this seeming high knowledge does not reflect in the expected expert level proficiency of practice.

Ascaris and Escherichia coli Inactivation in an Ecological Sanitation System in Port-au-Prince, Haiti.

The goal of this study was to evaluate the microbial die-off in a latrine waste composting system in Port-au-Prince, Haiti. Temperature data and samples were collected from compost aged 0-12+ months. Samples collected from compost bin centers and corners at two depths were assessed for moisture content, E. coli concentration, and Ascaris spp. viability. Center temperatures in compost bins were all above 58 °C, while corner temperatures were 10 - 20 °C lower. Moisture content was 67 ± 10% in all except the oldest compost. A 4-log reduction in E. coli was observed over the first sixteen weeks of composting at both locations and depths, after which E. coli was undetectable (LOD: 142 MPN g(-1) dry weight). In new compost, 10.4% and 8.3% of Ascaris eggs were viable and fully embryonated, respectively. Percent viability dropped to zero in samples older than six weeks. These findings indicate that the Haitian EcoSan composting process was effective in inactivating E. coli and Ascaris spp. in latrine waste within sixteen weeks. This study is one of the first to document efficacy of an ecological sanitation system under field conditions and provides insight into composting methods and monitoring for other international settings.

Environmental surveillance for toxigenic Vibrio cholerae in surface waters of Haiti.

Epidemic cholera was reported in Haiti in 2010, with no information available on the occurrence or geographic distribution of toxigenic Vibrio cholerae in Haitian waters. In a series of field visits conducted in Haiti between 2011 and 2013, water and plankton samples were collected at 19 sites. Vibrio cholerae was detected using culture, polymerase chain reaction, and direct viable count methods (DFA-DVC). Cholera toxin genes were detected by polymerase chain reaction in broth enrichments of samples collected in all visits except March 2012. Toxigenic V. cholerae was isolated from river water in 2011 and 2013. Whole genome sequencing revealed that these isolates were a match to the outbreak strain. The DFA-DVC tests were positive for V. cholerae O1 in plankton samples collected from multiple sites. Results of this survey show that toxigenic V. cholerae could be recovered from surface waters in Haiti more than 2 years after the onset of the epidemic.

One-year functional and anatomic outcomes of robotic sacrocolpopexy versus vaginal extraperitoneal colpopexy with mesh.

OBJECTIVES: This study aimed to evaluate and compare 1-year anatomic and functional outcomes in patients undergoing transvaginal versus transabdominal repair of pelvic organ prolapse (POP) with synthetic mesh reinforcement. METHODS: We conducted a retrospective, matched cohort study of patients undergoing robotic-assisted laparoscopic sacrocolpopexy (RALSC) and vaginal extraperitoneal colpopexy (VEC) with synthetic mesh from December 2008 to March 2011. We compared the preoperative to postoperative changes in anatomic, quality of life, and functional outcomes between groups after 1 year of follow-up. One-year surgical satisfaction was also assessed. RESULTS: Thirty-eight RALSC patients met the inclusion criteria and were matched by age and month of surgery to 38 VEC patients. Of those, 31 RALSC and 30 VEC patients (80%) had complete 1-year data. Preoperative to postoperative outcomes were similar in both groups with similar improvement seen in anatomic Pelvic Organ Prolapse Quantification measures as well as functional questionnaire scores. Both groups demonstrated high surgical satisfaction. Symptom distress inventory scales revealed 84% and 90% resolution of symptomatic "bulge" in RALSC and VEC patients, respectively (P = 0.74). The RALSC group had a significantly greater operative time by approximately 96 minutes and greater use of general anesthesia (P = <0.001). No difference was noted in blood loss, hospital days, or return to normal voiding between groups. CONCLUSIONS: Transabdominal and transvaginal techniques of colpopexy using synthetic mesh implants for POP have been shown in this retrospective cohort study to improve quality of life and anatomic measures with similar outcomes. Robotic-assisted laparoscopic sacrocolpopexy results in a greater use of general anesthesia and longer operative time.

Preventing maritime transfer of toxigenic Vibrio cholerae.

Organisms, including Vibrio cholerae, can be transferred between harbors in the ballast water of ships. Zones in the Caribbean region where distance from shore and water depth meet International Maritime Organization guidelines for ballast water exchange are extremely limited. Use of ballast water treatment systems could mitigate the risk for organism transfer.

Toxigenic Vibrio cholerae O1 in water and seafood, Haiti.

During the 2010 cholera outbreak in Haiti, water and seafood samples were collected to detect Vibrio cholerae. The outbreak strain of toxigenic V. cholerae O1 serotype Ogawa was isolated from freshwater and seafood samples. The cholera toxin gene was detected in harbor water samples.

Vaginal hysterectomy at the time of transvaginal mesh placement.

INTRODUCTION: : Previous investigations have shown an increased risk of mesh erosion when concomitant vaginal hysterectomy is performed at the time of transvaginal reconstruction with mesh. We hypothesize that vaginal hysterectomy can be performed without a high risk of erosion. METHODS: : This is a retrospective, repeated-measures study of women with uterovaginal prolapse who underwent vaginal hysterectomy and pelvic reconstruction with a transvaginal mesh technique using the Prolift system. Mesh was never placed behind the cuff closure and "T" incisions were not used. We compared preoperative quality-of-life and Pelvic Organ Prolapse Quantification values to postoperative values. RESULTS: : Forty women met the study criteria. The median length of follow-up was 12 months (range 4-43 months). Thirty-two (80%) of the women had at least 1 year of follow-up. Significant improvements were found in all quality-of-life measures. Except for genital hiatus and perineal body length, a significant change was seen in all Pelvic Organ Prolapse Quantification measures. The greatest mean change found was for point "C" going from +2.4 to -6.8 cm (P < 0.001). There was 1 (2.5%) mesh erosion. CONCLUSIONS: : When incisions for mesh placement are kept separate from the vaginal cuff, transvaginal mesh reconstruction can be safely performed at the time of hysterectomy.

Mutant p53 protein in serum could be used as a molecular marker in human breast cancer.

p53 wild-type is a tumor suppressor gene involved in DNA gene transcription or DNA repair mechanisms. When damage to DNA is unrepairable, p53 induces programmed cell death (apoptosis). The mutant p53 gene is the most frequent molecular alteration in human cancer, including breast cancer. Here, we analyzed the genetic alterations in p53 oncogene expression in 55 patients with breast cancer at different stages and in 8 normal women. We measured by ELISA assay the serum levels of p53 mutant protein and p53 antibodies. Immunohistochemistry and RT-PCR using specific p53 primers as well as mutation detection by DNA sequencing were also evaluated in breast tumor tissue. Serological p53 antibody analysis detected 0/8 (0%), 0/4 (0%) and 9/55 (16.36%) positive cases in normal women, in patients with benign breast disease and in breast carcinoma, respectively. We found positive p53 mutant in the sera of 0/8 (0.0%) normal women, 0/4 (0%) with benign breast disease and 29/55 (52.72%) with breast carcinoma. Immunohistochemistry evaluation was positive in 29/55 (52.73%) with mammary carcinoma and 0/4 (0%) with benign breast disease. A very good correlation between p53 mutant protein detected in serum and p53 accumulation by immunohistochemistry (83.3% positive in both assays) was found in this study. These data suggest that detection of mutated p53 could be a useful serological marker for diagnostic purposes.

Immunodeficiency in children with acute lymphoblastic leukemia after completion of modern aggressive chemotherapeutic regimens.

OBJECTIVE: To determine the prevalence, duration, and a potential cause of humoral defect(s) in children with acute lymphoblastic leukemia (ALL) at least 1 year after completion of chemotherapy. STUDY DESIGN: Antibody titers for mumps, rubeola, rubella, tetanus and diphtheria toxoid, poliovirus serotypes 1, 2,and 3, Haemophilus influenzae type b, varicella, and hepatitis B were obtained from 100 children with ALL. Children with non-protective titers to these microbial antigens were re-vaccinated and re-studied after anamnestic vaccine challenge. RESULTS: The percent of children with ALL who had protective titers was markedly less than that anticipated for immunized control subjects. Longitudinally, many titers fluctuate between protective and non-protective antibody responses after re-immunization. The chemotherapy protocol used did not affect the ability of these children to express protective antibody responses. T-, B-, and NK-cell numbers and proliferative responses to mitogens were all normal. Age correlated with titer results for certain vaccines. CONCLUSIONS: Children in remission from ALL have a high prevalence of humoral immune defects that are not related to any specific chemotherapy regimen. This antibody deficiency may place children with ALL at risk for the development of these bacterial and viral diseases, even after completion of chemotherapy. Pediatricians, oncologists, or both should periodically monitor humoral immunity after chemotherapy and re-vaccinate these children, as needed, to ensure prolonged immunoprotection.

Classification of Histoplasma capsulatum isolates by restriction fragment polymorphisms.

Twenty isolates of the dimorphic, pathogenic fungus Histoplasma capsulatum were divided into three classes based on comparisons of restriction enzyme digests of their mitochondrial DNA and rDNA. The majority of isolates, including most North American strains and the African H. capsulatum var. duboisii variants, belong to class 2. Isolates from Central America and South America make up class 3. The attenuated Downs strain is the only member of class 1.
