Comparison of short-term and long-term protocols for stabilization and preservation of RNA and DNA of Leishmania, Trypanosoma, and Plasmodium

Molecular tools continue to be important in the prevention and control of parasitic diseases. However, using these techniques directly in the field remains a major challenge. Therefore, the preservation of clinical samples collected from endemic field areas for later analysis remains an important preanalytical process. This study aimed at identifying a suitable protocol for stabilization and preservation of RNA and DNA in bioclinical specimens for Trypanosoma, Leishmania, and Plasmodium research. Both spiked and unspiked blood samples were preserved in 7 protocols (different media; storage temperatures). Samples were evaluated for possible degradation of DNA and RNA along the storage duration up to the 10th week. Nucleic acid targets were assessed as follows: (i) Trypanosoma and Plasmodium RNA analysis was done using real-time nucleic acid sequence-based amplification (RT-NASBA) for 18S rRNA and for stage-specific Pfs25 mRNA, respectively; (ii) Trypanosoma DNA assessment analysis was conducted by using a conventional PCR for 18S rDNA; (iii) Leishmania RNA analysis was performed with a quantitative NASBA for 18S rRNA and Leishmania DNA assessment with an RT-PCR for 18S rDNA. Findings suggested that a newly developed L3™ buffer proved to be reliable and suitable for both short- and long-term preservation of parasite nucleic acid material. This buffer is envisaged to be suitable for utilization in field situations where resources are limited.     

History of violence and subjective health of mother and child

Objective: To study the self-reported prevalence of experienced violence among a cohort of women about two years after giving birth, their health during pregnancy, pregnancy outcomes and their experience of their child’s health.

Setting and subjects: In 2011, a total of 657 women participated in phase III of the Childbirth and Health Cohort Study in Icelandic Primary Health Care, 18 to 24 months after delivery. The women had previously participated in phase I around pregnancy week 16 and phase II 5–6 months after delivery. Data were collected by postal questionnaires.

Main outcome measures: Women’s reported history of experienced violence, sociodemographic and obstetric background, self-perceived health, the use of medications and their child’s perceived health.

Results: In phase III, 16% of women reported experiencing violence. These women felt less support from their current partner (p?p?p?p?p?p?=?0.008).

Conclusions: Our study confirms that a history of violence is common among women. A history of violence is associated with various maternal health problems during and after pregnancy, a higher rate of caesarean sections and maternal reports of health problems in their child 18–24 months after birth.

• KEY POINTS

• Violence is a major concern worldwide. Understanding the impact of violence on human health and developing effective preventive measures are important elements of any public health agenda.

• ??The reported prevalence of experiencing violence was 16% among women attending antenatal care in the primary health care setting in Iceland.

• ??Women with a history of violence reported worse health in general during pregnancy and delivered more often by caesarean section, compared to women with no such history.

• ??Mothers with a history of violence also evaluated the general health of their child as worse than women with no such history.

• ??The findings of this study support the importance of recognizing and addressing experienced violence among women in primary care.

     

Rates and risks of transmission of smallpox and mechanisms of prevention

In 1980, the World Health Organization declared smallpox eradicated from the world; the last known natural case had occurred in Somalia in 1977, and the United States had stopped routinely vaccinating its citizens in 1972. However, with increasing concerns regarding domestic and international terrorism, smallpox has resurfaced as a potential threat to global health. We review the direct and indirect modes of smallpox transmission and how patterns of transmission vary substantially, depending on the severity of circulating disease, vaccination status, environmental and socioeconomic factors, and the setting of an outbreak. We examine mechanisms for controlling outbreaks of disease and preventing further transmission in the event of an outbreak, with an emphasis on smallpox vaccination.

Prevalence and severity of nausea and vomiting of pregnancy and effect of vitamin supplementation.

OBJECTIVE: Although nausea and vomiting of pregnancy is the most common medical condition during pregnancy, there are many unanswered questions regarding its cause, epidemiologic features and optimal management. The objectives of this study were to ascertain the prevalence of nausea and vomiting in a sample of Canadian women, to characterize the distribution of their severity and to investigate the role of vitamin B6 deficiency in their etiology. DESIGN: Prospective study. SETTING: Antenatal counselling service for pregnant women. PATIENTS: Three cohorts of women: a prospective, population-based cohort of 193 women, to estimate the rate and severity of nausea and vomiting (cohort A); a cohort of 555 women who sought advice for nausea with or without vomiting, to study the correlation between the maximal daily number of episodes of vomiting and maximal weight loss (cohort B); and a prospective cohort of 301 women who reported vomiting, to correlate vitamin supplementation with vomiting (cohort C). INTERVENTIONS: All 3 cohorts were interviewed during the counselling session, and cohort B was followed up prospectively. OUTCOME MEASURES: Frequency of nausea and vomiting, weight loss, maximal number of daily episodes of vomiting, rate of multivitamin supplementation. RESULTS: Overall, 67% of the women in cohort A reported experiencing nausea or vomiting, or both; 22% reported vomiting, and 9% experienced weight loss. In cohort B there was a significant correlation between the maximal number of daily episodes of vomiting and maximal weight loss, although there was wide variation (r2 = 0.25, p < 0.001). There was a highly significant correlation between the number of daily vomiting episodes and mean weight loss (r2 = 0.99). In cohort C, vomiting was significantly associated with lack of supplementation with multivitamins before 6 weeks' gestation (p = 0.002). CONCLUSIONS: The relation between number of daily vomiting episodes and mean weight loss may serve as a clinical tool to assess the severity of nausea and vomiting in pregnancy and the success of anti-emetics and rehydration regimens. Further study is needed to elucidate the biologic basis of the observed association between vomiting and lack of multivitamin supplementation in early pregnancy.
