Homeopathy: A State of the Science Review With Recommendations for Practical Therapies in Midwifery Practice

A substantial proportion of adults and children in the United States use complementary and alternative health practices, including homeopathy. Many homeopathic therapies are readily available over the counter, and many individuals access and self-administer these therapies with little or no guidance from health care practitioners. In addition, patients and health care providers are often confused by terminologies associated with complementary practices and may be unable to distinguish homeopathy from naturopathy, herbalism, holistic medicine, Ayurveda, traditional Chinese medicine, or other forms of health care. Compared with European and Asian countries, education in the United States about complementary and alternative health practices is not typically found within traditional nursing, midwifery, or medical education curricula. Given this lack of education and the broad acceptance and popularity of homeopathy, it is necessary for health care practitioners to improve their knowledge regarding similarities and differences among therapies so they can fully inform and make appropriate recommendations to patients. The intent of this article is therefore to examine the state of existing science of homeopathy, distinguish it from other complementary methods, and provide midwives and women's health care providers with an introduction to common homeopathic therapies that may be recommended and safely used by persons seeking midwifery care. This review also presents the evidence base, pharmacology, manufacturing, and regulation of homeopathic therapies. We also consider controversies and misunderstandings regarding safety and efficacy of homeopathic remedies relevant to women and birthing persons. Examples of practical applications of homeopathic therapies for use in midwifery practice are introduced. Implications for practice and sample guidelines are included.     

Unmappable ventricular tachycardia after an old myocardial infarction. Long-term results of substrate modification in patients with an implantable cardioverter defibrillator

Purpose  

The frequent occurrence of ventricular tachycardia can create a serious problem in patients with an implantable cardioverter defibrillator. We assessed the long-term efficacy of catheter-based substrate modification using the voltage mapping technique of infarct-related ventricular tachycardia and recurrent device therapy.     

Prevalence of apical periodontitis detected in cone beam CT images of a Brazilian subpopulation

Objectives

The aim of this study was to determine the prevalence of apical periodontitis (AP) detected in cone beam CT (CBCT) images from a database.

Methods

CBCT images of 300 Brazilian patients were assessed. AP images were measured in three dimensions. Age, gender, number and location of total teeth in each patient were considered. AP location was considered according to tooth groups. The extent of AP was determined by the largest diameter in any of the three dimensions. Percentages and the χ² test were used for statistical analysis.

Results

AP was found in 51.4% of the patients and in 3.4% of the teeth. Higher prevalence of AP was found in 60- to 69-year-olds (73.1%) and in mandibular molars (5.9%) (p < 0.05). Inadequate endodontic treatment presented higher prevalence of AP (78.1%).

Conclusions

AP can be frequently found in CBCT examinations. The presence of AP has a significant association with patients'' age, and tooth type and condition. CBCT databases are useful for cross-sectional studies about AP prevalence in a population.     

Inequalities in full immunization coverage: trends in low- and middle-income countries

ObjectiveTo investigate disparities in full immunization coverage across and within 86 low- and middle-income countries.MethodsIn May 2015, using data from the most recent Demographic and Health Surveys and Multiple Indicator Cluster Surveys, we investigated inequalities in full immunization coverage – i.e. one dose of bacille Calmette-Guérin vaccine, one dose of measles vaccine, three doses of vaccine against diphtheria, pertussis and tetanus and three doses of polio vaccine – in 86 low- or middle-income countries. We then investigated temporal trends in the level and inequality of such coverage in eight of the countries.FindingsIn each of the World Health Organization’s regions, it appeared that about 56–69% of eligible children in the low- and middle-income countries had received full immunization. However, within each region, the mean recorded level of such coverage varied greatly. In the African Region, for example, it varied from 11.4% in Chad to 90.3% in Rwanda. We detected pro-rich inequality in such coverage in 45 of the 83 countries for which the relevant data were available and pro-urban inequality in 35 of the 86 study countries. Among the countries in which we investigated coverage trends, Madagascar and Mozambique appeared to have made the greatest progress in improving levels of full immunization coverage over the last two decades, particularly among the poorest quintiles of their populations.ConclusionMost low- and middle-income countries are affected by pro-rich and pro-urban inequalities in full immunization coverage that are not apparent when only national mean values of such coverage are reported.     

Cancer-promoting effect of Taiwan betel quid in hamster buccal pouch carcinogenesis

OBJECTIVE: To investigate the cancer-promoting effect of Taiwan betel quid in hamster buccal pouch carcinogenesis.
MATERIALS AND METHODS: Two hundred and fifty-two non-inbred mate adult Syrian golden hamsters were randomly divided into six groups, each containing forty-two animalS. A treatment regimen over a 14-week experimental period was employed with six animals per group being killed at seven different periods (every 2 weeks). The right buccal pouch of each animal was painted three times a week with various combinations of 7, 12-dimethylbenz[a]anthracene (DMBA), Taiwan betel quid extract, dimethyl sulfoxide (DMSO) and mineral oil.
RESULT: Both the number and size of tumors in animals concurrently treated with DMBA and betel quid were significantly higher than those in animals treated with DMBA alone in each killing period of 8, 10, 12 and 14 weekS. No visible tumors but hyperkeratosis and acanthosis were observed in pouches treated with betel quid alone for all killing periods.
CONCLUSION: Our results indicate Taiwan betel quid may be a co-carcinogen in human oral carcinogenesis, if extrapolation can be made from the current animal study.     

替加环素和其他广谱抗菌药物对产丝氨酸碳青霉烯酶和金属β内酰胺酶的肠杆菌科细菌的抗菌活性:SENTRY监测网络的报告

肠杆菌科细菌对碳青霉烯类抗生素的耐药性可以由过量产生AmpC酶且同时外膜孔道蛋白大量缺失和（或）外排泵过量表达,或产生能水解碳青霉烯类的β内酰胺酶引起。这些碳青霉烯酶可以分为金属β内酰胺酶（MSL）和丝氨酸碳青霉烯酶两类。替加环素是一类半合成的甘氨酰环素类抗菌药物,对其他类抗生素耐药的细菌通常对替加环素无交叉耐药。
