Botulinum toxin injection for post‐stroke spasticity

Introduction: The aim of this study was to evaluate test feasibility, validity, and reproducibility of the rate of force development scaling factor (RFD‐SF) for the hip muscles. Methods: Feasibility was assessed as the testing compliance, validity as the ability to compute the RFD‐SF from a linear regression, and reproducibility with a test–retest design in 20 healthy subjects. Reliability and agreement (reproducibility) were evaluated using intraclass correlation coefficient (ICC_3,1) and percent standard error of measurement (SEM), respectively. Results: The RFD‐SF testing protocol was completed successfully by all subjects, although the analysis had to be modified for hip rotators. Reliability was high (ICC_3,1 > 0.70) for all muscles except hip abductors (ICC_3,1 = 0.69) and internal rotators (ICC_3,1 = 0.58). Agreement was high for all muscles (SEM < 10%). Conclusions: Hip adductor, flexor, and external rotator RFD‐SF can be evaluated with confidence, provided the analysis is modified for external rotators, whereas hip abductor and internal rotator RFD‐SF assessment is not recommended.

Gastrointestinal parasites in rural dogs and cats in Selangor and Pahang states in Peninsular Malaysia

To estimate the current prevalence of gastrointestinal (GI) parasites in dogs and cats, a total of 105 fresh faecal samples were collected from rural areas in Peninsular Malaysia. Each faecal sample was examined for the presence of GI parasites by microscopic examination after formalin-ether concentration technique and for protozoa, trichrome and Ziehl-Neelsen staining were employed. The overall prevalence of GI parasitic infection was 88.6% (95% CI = 82.5–94.7) in which 88.3% of dogs and 89.3% of cats were infected with at least one parasites species, respectively. There were 14 different GI parasites species (nematodes, cestodes and protozoa) detected, including Ancylostoma spp. (62.9%), Toxocara spp. (32.4%), Trichuris vulpis (21.0%), Spirometra spp. (9.5%), Toxascaris leonina (5.7%), Dipylidium caninum (4.8%), Ascaris spp. (2.9%), Hymenolepis diminuta (1.0%) and others. General prevalence of GI parasites showed a significant difference between helminth (84.4%) and protozoa (34.3%) infections. Monoparasitism (38.1%) was less frequent than polyparasitism (46.7%). As several of these GI parasites are recognized as zoonotic agents, the results of this investigation revealed that local populations may be exposed to a broad spectrum of zoonotic agents by means of environmental contamination with dogs and cats faeces and this information should be used to mitigate public health risks. Prevention and control measures have to be taken in order to reduce the prevalence rates especially in socioeconomically disadvantaged communities where animals live in close proximity to people, poor levels of hygiene and overcrowding together with a lack in veterinary attention and zoonotic awareness.     

Motivational Interviewing in Improving Oral Health: A Systematic Review of Randomized Controlled Trials

Background: The control and management of many oral health conditions highly depend on one's daily self‐care practice and compliance to preventive and curative measures. Conventional (health) education (CE), focusing on disseminating information and giving normative advice, is insufficient to achieve sustained behavioral changes. A counseling approach, motivational interviewing (MI), is potentially useful in changing oral health behaviors. This systematic review aims to synthesize the evidence on the effectiveness of MI compared with CE in improving oral health. Methods: Four databases (PubMed MEDLINE, Web of Science, Cochrane Library, and PsycINFO) were searched to identify randomized controlled trials that evaluated the effectiveness of MI compared with CE in changing oral health behaviors and improving oral health of dental patients and the public. The scientific quality of the studies was rated, and their key findings were qualitatively synthesized. Results: The search yielded 221 potentially relevant papers, among which 20 papers (on 16 studies) met the eligibility criteria. The quality of the studies varied from 10 to 18 out of a highest possible score of 21. Concerning periodontal health, superior effect of MI on oral hygiene was found in five trials and was absent in two trials. Two trials targeting smoking cessation in adolescents failed to generate a positive effect. MI outperformed CE in improving at least one outcome in four studies on preventing early childhood caries, one study on adherence to dental appointments, and two studies on abstinence of illicit drugs and alcohol use to prevent the reoccurrence of facial injury. Conclusions: Reviewed randomized controlled trials showed varied success of MI in improving oral health. The potential of MI in dental health care, especially on improving periodontal health, remains controversial. Additional studies with methodologic rigor are needed for a better understanding of the roles of MI in dental practice.     

Association Between Periodontitis Needing Surgical Treatment and Subsequent Diabetes Risk: A Population‐Based Cohort Study

Background: It is well known that patients with diabetes have higher extent and severity of periodontitis, but the backward relationship is little investigated. The relationship between periodontitis needing dental surgery and subsequent type 2 diabetes mellitus (DMT2) in those individuals without diabetes was assessed. Methods: This is a retrospective cohort study using data from the national health insurance system of Taiwan. The periodontitis cohort involved 22,299 patients, excluding those with diabetes already or those diagnosed with diabetes within 1 year from baseline. Each study participant was randomly frequency matched by age, sex, and index year with one individual from the general population without periodontitis. Cox proportional hazards regression analysis was used to estimate the influence of periodontitis on the risk of diabetes. Results: The mean follow‐up period is 5.47 ± 3.54 years. Overall, the subsequent incidence of DMT2 was 1.24‐fold higher in the periodontitis cohort than in the control cohort, with an adjusted hazard ratio of 1.19 (95% confidence interval = 1.10 to 1.29) after controlling for sex, age, and comorbidities. Conclusions: This is the largest nation‐based study examining the risk of diabetes in Asian patients with periodontitis. Those patients with periodontitis needing dental surgery have increased risk of future diabetes within 2 years compared with those participants with periodontitis not requiring dental surgery.
