Trên thế giới, nhiều nghiên cứu về tự trọng đã được tiến hành trên nhóm khách thể là trẻ em và trẻ vị thành niên, tuy nhiên nhóm người trưởng thành từ 18 tuổi trở lên lại chưa nhận được sự quan tâm thích đáng. Ở Việt Nam, tình hình cũng tương tự, đặc biệt, các nghiên cứu về sự thỏa mãn nhu cầu tự trọng (Self- Esteem) tiếp cận dựa trên khung lý thuyết của Abraham Maslow còn rất thiếu vắng. Mục đích của nghiên cứu này nhằm mô tả sự thỏa mãn nhu cầu tự trọng của 301 người trưởng thành, độ tuổi 18 - 60 (Mean = 34.6, SD = 0.77) tại Việt Nam tiếp cận theo lý thuyết về Tháp nhu cầu của A. Maslow. Thang đo sự thỏa mãn nhu cầu tâm lý (Psychological Needs Satisfaction) của David Lester và cộng sự (1990), được sử dụng trong nghiên cứu này. Kết quả nghiên cứu cho thấy: (i) Sự thỏa mãn nhu cầu tự trọng của người trưởng thành tại Việt Nam có điểm số trung bình cao nhất trong số 5 nhu cầu theo lý thuyết của A.Maslow; (ii) Các nhu cầu trong năm nhu cầu theo khung lý thuyết đều có mối tương quan mạnh với nhau, trong đó tương quan mạnh nhất là sự thỏa mãn nhu cầu tự trọng với nhu cầu hiện thực hóa bản thân; (iii) Có sự khác biệt về sự thỏa mãn nhu cầu tự trọng giữa các nhóm tuổi khác nhau và giữa các nhóm trình độ học vấn khác nhau, tuy nhiên chưa đủ bằng chứng để kết luận có sự khác biệt theo tiêu chí giới tính, địa bàn nghiên cứu, kiểu tính cách và mức thu nhập.

State Physician Health Programs (PHPs) assess, support, and monitor physicians with mental, behavioral, medical, and substance abuse problems. Since their formation in the 1970s, PHPs have offered support groups following the 12-step model for recovery from substance use disorders (SUDs). However, few programs have developed support groups for physicians without SUDs. This study at the Massachusetts PHP (Physician Health Services Inc.) represents the first effort to survey physician attitudes concerning a unique support group that goes beyond classic addiction models. The group was initiated because of the observation that physicians with problems other than SUDs did not fit easily into the 12-step framework. It was hypothesized that such a group would be effective in helping participants control workplace stress, improve professional and personal relationships, and manage medical and psychiatric difficulties. With a response rate of 43% (85 respondents), the survey identified a strong overall impact of the Physician Health Services Inc. support group, identifying positive effects in all areas of personal and professional life: family and friends, wellness, professional relationships, and career. Respondents identified the role of the facilitator as particularly important, underscoring the facilitator's capacity to welcome participants, manage interactions, set limits, and maintain a supportive emotional tone. The implications for physician health extend from supporting a broader application of this model to using a skilled facilitator to manage groups intended to reduce the stress and burnout of present-day medical practice. The results encourage PHPs, hospitals, medical practices, and physician groups to consider implementing facilitated support groups as an additional tool for maintaining physician health.

The purpose of this study was to evaluate the bone formation capability of polyetheretherketone (PEEK) and carbon fiber-reinforced PEEK (CFR-PEEK) implants coated with different titanium and hydroxyapatite plasma-sprayed layers after 2 and 12 weeks. In six sheep 108 implants were placed in the pelvis. Altogether six different surface modifications were tested. After 2 and 12 weeks, n = 3 implants per group were examined histologically and n = 6 implants per group were tested by a pull-out test. Biomechanically (p = 0.001) as well as histologically (p > 0.05) surface coating of PEEK/CFR-PEEK led to an increase of osseointegration from 2 to 12 weeks. After 12 weeks, coated implants demonstrated significant (p < 0.001) higher pull-out values in comparison to uncoated implants. Overall, the double coating (titanium bond layer and hydroxyapatite top layer) showed the most favorable results after 2 and 12 weeks. Plasma-sprayed titanium and hydroxyapatite coatings on PEEK or CFR-PEEK demonstrated a significant improvement of osseointegration. © 2015 Wiley Periodicals, Inc.

Isoflurane is currently the most common volatile anaesthetic used in laboratory mice, whereas in human medicine the more modern sevoflurane is often used for inhalation anaesthesia. This study aimed to characterize and compare the clinical properties of both anaesthetics for inhalation anaesthesia in mice. In an approach mirroring routine laboratory conditions (spontaneous breathing, gas supply via nose mask, preventing hypothermia by a warming mat) a 50 min anaesthesia was performed. Anaesthetics were administered in oxygen as carrier gas at standardized dosages of 1.5 minimum alveolar concentrations, which was 2.8% for isoflurane and 4.9% for sevoflurane. Both induction and recovery from anaesthesia proceeded quickly, within 1-2 min. During anaesthesia, all reflex testing was negative and no serious impairment of vital functions was found; all animals survived. The most prominent side-effect during anaesthesia was respiratory depression with hypercapnia, acidosis and a marked decrease in respiration rate. Under anaesthesia, heart rate and core body temperature remained within the normal range, but were significantly increased for 12 h after anaesthesia. Locomotor activity, daily food and water consumption and body weight progression showed no abnormalities after anaesthesia. No significant difference was found between the two anaesthetics. In conclusion, isoflurane and sevoflurane provided an equally reliable anaesthesia in laboratory mice.

Salmonellosis was diagnosed in garden birds from 198 incidents in Scotland between September 1995 and August 2008. Salmonellosis was essentially a disease of finches in the north of Scotland, but in the south of Scotland it was also a problem in house sparrows. Almost all of the incidents were caused by Salmonella Typhimurium phage types 40 or 56/variant, but regional variation in phage types was observed. In the north of Scotland, one phage type (DT 40) predominated, but in the south of Scotland two phage types were commonly isolated (DTs 40 and 56/variant, with the latter the more common of the two phage types). This regional difference was statistically significant for salmonellosis in greenfinches, chaffinches and ‘other garden birds’, but not for house sparrows. Different temporal patterns for different species of bird and different phage types were also observed within regions. These findings suggest that the epidemiology of salmonellosis in garden birds varies depending on the phage type of Salmonella and the species of garden bird, with additional regional differences depending on the wild bird populations and the phage types of Salmonella in circulation. An awareness of these differences will help when formulating guidelines aimed at reducing the impact of salmonellosis in garden birds.

Neste trabalho foi analisado os impactos do aumento de 1º C de temperatura na evapotranspiração e vazão na bacia hidrográfica do rio Ipojuca (PE). Os resultados obtidos indicam que o comportamento da evapotranspiração acompanha a tendência de aumento de temperatura tanto durante os períodos de menor disponibilidade hídrica quanto nos de maior. Já para a vazão, a uma tendência de diminuição durante o período de maiores vazões; para o período de menor vazão foram observadas tendências variáveis. Apesar dos resultados obtidos serem para um modelo hidrológico de dois parâmetros, a tendência de modificação na vazão deve indicar certa preocupação com relação aos recursos hídricos da região, já que resultados de outros pesquisadores indicam mudanças no comportamento da vazão relacionados a diferentes efeitos antrópicos.

Phenotypic and phylogenetic studies were performed on four Campylobacter-like organisms recovered from three seals and a porpoise. Comparative 16S rRNA gene sequencing studies demonstrated that the organisms represent a hitherto unknown subline within the genus Campylobacter, associated with a subcluster containing Campylobacter jejuni, Campylobacter coli and Campylobacter lari. DNA-DNA hybridization studies confirmed that the bacteria belonged to a single species, for which the name Campylobacter insulaenigrae sp. nov. is proposed. The type strain of Campylobacter insulaenigrae sp. nov. is NCTC 12927(T) (=CCUG 48653(T)).

We report the failure of a femoral component in a unicompartmental knee replacement 6 years after implantation. The implant fractured 15 mm from the anterior tip, and scanning electron microscopy confirmed fatigue to be the cause of failure. The clinical and laboratory findings are presented, and the causes and implications of this mode of implant failure are discussed.
