First description of Sarcocystis species infecting Barbary sheep (Ammotragus lervia).

Barbary sheep (Ammotragus lervia) is a North African native wild Caprinae, introduced in the 1970s in new territories such as Spain, the USA, and Mexico. Here, we describe Sarcocystis species in Barbary sheep. Sarcocysts were found in 19 out of 56 adult A. lervia in Southern Spain and characterized morphologically and molecularly. By light microscopy, sarcocysts had thin (< 1 µm) or thick (> 2 µm) walls. By transmission electron microscopy, sarcocysts with thick walls had Type 14 villar protrusions corresponding to S. tenella/S. capracanis of domestic sheep (Ovis aries) or goats (Capra hircus). Sarcocysts with thin walls had Type 7b villar protrusions that corresponded to S. arieticanis/S. hircicanis of domestic sheep or goats. Molecular analyses allowed the identification of only thick-walled Sarcocystis species. Six sarcocysts were assigned to S. tenella (99.2-100% and 95.6-100% sequence similarity within 18S rRNA and COI, respectively) and 19 sarcocysts were assigned to S. capracanis (98.5-99.8% and 97.9-99.0% sequence similarity within 18S rRNA and COI, respectively). Further studies are needed for taxonomic identification of sarcocysts in Barbary sheep because Sarcocystis species in sheep and goats are not cross transmissible despite morphological similarities.

Osteoarthritis in Latin America: Study of Demographic and Clinical Characteristics in 3040 Patients.

BACKGROUND: Latin America is a heterogeneous region made up of different populations, cultures, latitudes, altitudes, and immigrants from different areas and ethnic groups. OBJECTIVE: The purpose of this study is to describe the clinical and demographic profile of patients with osteoarthritis (OA) evaluated by a selected group of rheumatologists in 13 Latin American countries. METHODS: A descriptive, observational, cross-sectional study was conducted in 13 Latin American countries of patients with symptomatic OA. Data were collected over a 3-month period using an ad hoc questionnaire to evaluate the clinical and demographic features of OA seen by rheumatologists. RESULTS: Among the 3040 patients, their average age was 62.5 years, and female-to-male ratio was 4.8:1. Patients with body mass index of greater than 30 kg/m or obesity was found in 38.2%. Approximately 88% had primary OA. Joints with OA were as follows: knee 31.2%, hand 9.5%, hand and knee 22.9%, proximal and distal interphalangeal joints (erosive OA) 6.5%, axial 6.6%, and hip 1.3%. Approximately 88.5% had radiographic severity of grade 2 or 3 on Kellgren-Lawrence scale (0-4). Nonsteroidal anti-inflammatory drugs were the predominant OA treatment included in combinations with glucosamine sulfate/chondroitin and viscosupplementation. Associated comorbidities included hypertension (39%), obesity (36.3%), diabetes mellitus (12%), and without comorbidity (12.7%). CONCLUSIONS: This is 1 of the largest population studies that evaluated the characteristics of OA in 3040 patients evaluated by rheumatologists in 13 Latin American countries. This study provides important data for each Latin American country to develop new health care planning in management of OA.

Effectiveness of Acupuncture in Dental Surgery: A Randomized, Crossover, Controlled Trial.

OBJECTIVES: The objective of this crossover clinical study was to evaluate the effectiveness of Energy Regulation with Acupuncture in clinical occurrences in impacted lower third molar surgeries. METHODS: The sample consisted of 22 patients with two impacted third molars, in symmetrical position; divided into two groups: Test Group (TG) with Real Energy Regulation Group and Sham Group (SG) with Acupuncture without Energy Regulation function. The extraction was performed 30 days apart. Energy flow (Ryodoraku Method) and energy regulation performed before extraction were measured. Heart Rate (HR) and Blood Pressure (BP) were evaluated before and after energy regulation and after surgery, residual edema was measured by facial measurements (angle of the mandible to tragus (A-T); angle of the mandible to labial commissure (A-LC); angle of the mandible to the wing of the nose (A-WN); angle of the mandible to the corner of the eye (A-CE); angle of the mandible to the chin (A-C); and mouth opening by the interincisal distance, before and after seven days of surgery. To quantify intraoperative bleeding (ml), blood was aspirated along with the saline solution using a portable vacuum pump adaptor. The amount of saline solution used was subtracted from the final amount of aspirated fluid. RESULTS: Mean of bleeding was lower in TG (p = 0.0392). There were significant differences between groups in facial distances: A-LC (p = 0.010), A-WN (p = 0.030) and A-C (p = 0.008). CONCLUSION: Energy regulation with real acupuncture was effective in reducing postoperative residual edema and intraoperative bleeding.

Patterns of Energy Imbalance of the Meridians in Patients with Temporomandibular Dysfunction.

Temporomandibular dysfunction (TMD) is a set of changes that affects the muscles of mastication, temporomandibular joint, teeth, and associated periodontal and orofacial structures. According to Traditional Chinese Medicine, the imbalance of energy (Qi) circulating in the acupuncture meridians is always the primary etiologic cause of any physical manifestation. The aim of this study was to describe the patterns of Qi imbalance in patients with TMD by means of an objective measurement. The clinical study was conducted at the Piracicaba Dental School (FOP/Unicamp), in Piracicaba-SP, Brazil. We evaluated 40 adult volunteers with TMD. The Qi measurement was carried out by the researcher using the Ryodoraku method using 24 points representing the 12 acupuncture meridians: LU9 (Taiyuan), PC7 (Daling), HT7 (Shemen), SI5 (Yanggu), TE4 (Yangchi), LI5 (Yangxi), SP3 (Taibai), LR3 (Taichong), KI3 (Taixi), BL64 (Jinggu), GB40 (Qiuxu), and ST42 (Chongyang). The average total Qi of 40 volunteers (21.7 µA ± 1.5), was below the normal range (40-60 µA) and was classified as deficiency of Qi (empty). The coupled meridians that showed the highest Qi imbalance were the kidney (29.4 µA ± 2.8) and bladder (13.8 µA ± 1). The Qi planes with greatest imbalance were the Shao Yang and Shao Yin. In conclusion, volunteers with TMD presented a pattern of Qi deficiency, and the most prevalent imbalance patterns identified were in the kidney and bladder coupled meridians and in the energetic planes Shao Yin (heart/kidney) and Shao Yang (triple energizer/gall bladder).
