Re-treatment of chronic hepatitis C patients after relapse: efficacy of peginterferon-alpha-2a (40 kDa) and ribavirin

SUMMARY. We conducted a randomized multinational study to determine whether 48 weeks of re-treatment with peginterferon- alpha-2a (40 kDa) plus ribavirin would induce a sustained virological response (SVR) in relapsed chronic hepatitis C patients. Patients who had previously relapsed during 24 weeks of untreated follow-up, after having achieved an end-of-treatment virological response with 24 weeks of peginterferon-alpha-2a (40 kDa)/ribavirin combination therapy, within a phase III trial, were studied. Although the recommended dosage was the same as that used at the end of the initial trial, adjustments were permitted. Data on serious adverse events, or adverse events that resulted in dose reductions or discontinuations, were collected. Following re-treatment, the overall SVR rate in the 64 patients was 55%. The SVR rates in patients infected with hepatitis C virus (HCV) genotype 1 and non-1 genotypes were 51% and 63%, respectively. Early (week 12) virological responses were seen in 39 patients (61%) and were predictive of an SVR. Re-treatment was well tolerated. The most frequent adverse events recorded were fatigue (5%) and abdominal pain (3%). Dosages of peginterferon-alpha-2a (40 kDa) and/or ribavirin were modified because of adverse events in 3% and 13% of patients, and because of laboratory abnormalities in 23% and 5% of patients, respectively. Thus, a 48-week course of peginterferon-alpha-2a (40 kDa) plus ribavirin induces an SVR in 55% of patients who relapsed during follow-up after 24 weeks of combination therapy. Physicians should not hesitate to offer re-treatment to patients who relapse after an initial, 24-week course of combination therapy, or who have prematurely stopped treatment because, for example, of laboratory abnormalities.

COMPARAÇÃO DA UTILIZAÇÃO DAS TÉCNICAS WATSU E RELAXAMENTO AQUÁTICO EM FLUTUAÇÃO ASSISTIDA NOS SINTOMAS DE ANSIEDADE, DEPRESSÃO E PERCEPÇÃO DA DOR

Este estudo teve como objetivo comparar o efeito do método Watsu e do relaxamento aquático em flutuação assistida em piscina, no tratamento da dor crônica. Também objetiva avaliar o efeito dos sintomas de depressão e ansiedade como co-fatores nesses tratamentos. A amostra é constituída por 23 indivíduos de ambos os sexos, acima de 18 anos. No método Watsu são atendidas 13 pessoas, sendo 11 mulheres e 02 homens. Na técnica de relaxamento assistido são atendidas 10 pessoas, sendo 07 mulheres e 03 homens, entre pacientes que procuram tratamento fisioterápico no centro clínico Escola de Fisioterapia da UMESP, com dor crônica. Os dados são colhidos através de entrevista estruturada. Aplicada escala associada para avaliar percepção de dor, questionário de avaliação de sintomas de depressão Beck, de Ansiedade Idate-Estado e Ansiedade Idate-Traço. Devido ao pequeno tamanho da amostra, as comparações entre os dois tipos de tratamento (Watsu e relaxamento) e, como os resultados obtidos são equivalentes em ambos os procedimentos, optou se por apresentar os resultados apenas das análises por métodos paramétricos (teste t de média, regressão linear e análise de variância). Não são observadas diferenças significativas entre os dois grupos em relação aos escores de ansiedade e depressão antes e após a realização da pesquisa. Em relação à comparação entre os dois grupos pesquisados, quanto à percepção de dor, observou-se que tanto o método de Watsu quanto as técnicas de relaxamento mostram um efeito significativo na redução da dor. Esta pesquisa sugere que o método Watsu é tão eficaz para o controle da dor quanto o método de relaxamento, porém, o grupo de pacientes submetidos ao método Watsu é constituído por pessoas com níveis de intensidade de dor iniciais maiores do que o grupo de relaxamento. Com isso, pode-se supor que a demanda por eficácia clinica é maior para o método Watsu. Outro achado interessante é que os níveis de ansiedade ou depressão presentes nos participantes não parecem influenciar a resposta ao efeito do tratamento sobre a dor. Novos estudos do tipo duplo-cego controlados são necessários para, além de confirmar a eficácia do método, ajudar a entender quais detalhes dos procedimentos da técnica Watsu são mais eficazes para cada tipo de dor e de estado afetivo do paciente.

Intern pharmacists as change agents to improve the practice of nonprescription medication supply: provision of salbutamol to patients with asthma

BACKGROUND: Earlier work established an evidence practice gap during provision of nonprescription salbutamol (albuterol). Pharmacist interns are hypothesized to be in a position to improve professional practice in the community pharmacy setting. OBJECTIVE: To explore the potential of intern pharmacists to improve the professional practice of community pharmacy staff in the provision of nonprescription salbutamol. METHODS: Intern pharmacists (n = 157) delivered an asthma intervention in 136 pharmacies consisting of an educational activity to pharmacy staff and a health promotion campaign to consumers. Post-intervention, simulated patients presented to 100 intervention and 100 control community pharmacies with a request for salbutamol. The appropriate outcome was medical referral for poor asthma control and correction of poor inhaler technique. Incidence and quantity of patient assessment and counseling provided during the visit were also assessed. Logistic regression was used to determine the predictors of medical referral. RESULTS: A doubling in the rate of medical referral was seen in the intervention group (19% vs 40%; p = 0.001). Assessment of reliever use frequency was the main predictor of medical referral (OR = 22.7; 95% CI 9.06 to 56.9). Correction of poor inhaler technique did not improve; however, a reduction in salbutamol supplied without patient assessment (23% vs 8%; p = 0.009) or counseling (75% vs 48%; p < 0.001) was noted. CONCLUSIONS: A doubling in the rate of medical referral showed a clear improvement in professional practice during the provision of nonprescription salbutamol. The improved patient outcome in the intervention group was due to increased assessment of reliever use frequency. Identification of poor inhaler technique remained near zero in both groups, which suggests that intern pharmacists were able to improve the current practice of community pharmacies yet were unable to establish a new practice behavior. This study provides evidence that intern pharmacists can act as change agents to improve pharmacy practice.

Provision of pharmaceutical care by community pharmacists:a comparison across Europe

Objective To investigate the provision of pharmaceutical care by community pharmacists across Europe and to examine the various factors that could affect its implementation. Methods A questionnaire-based survey of community pharmacies was conducted within 13 European countries. The questionnaire consisted of two sections. The first section focussed on demographic data and services provided in the pharmacy. The second section was a slightly adapted version of the Behavioral Pharmaceutical Care Scale (BPCS) which consists of three main dimensions (direct patient care activities, referral and consultation activities and instrumental activities). Results Response rates ranged from 10–71% between countries. The mean total score achieved by community pharmacists, expressed as a percentage of the total score achievable, ranged from 31.6 (Denmark) to 52.2% (Ireland). Even though different aspects of pharmaceutical care were implemented to different extents across Europe, it was noted that the lowest scores were consistently achieved in the direct patient care dimension (particularly those related to documentation, patient assessment and implementation of therapeutic objectives and monitoring plans) followed by performance evaluation and evaluation of patient satisfaction. Pharmacists who dispensed higher daily numbers of prescriptions in Ireland, Germany and Switzerland had significantly higher total BPCS scores. In addition, pharmacists in England and Ireland who were supported in their place of work by other pharmacists scored significantly higher on referral and consultation and had a higher overall provision of pharmaceutical care. Conclusion The present findings suggest that the provision of pharmaceutical care in community pharmacy is still limited within Europe. Pharmacists were routinely engaged in general activities such as patient record screening but were infrequently involved in patient centred professional activities such as the implementation of therapeutic objectives and monitoring plans, or in self-evaluation of performance.

Subject -centered and problem -based approaches to teaching clinical competence in physical therapy

Physical therapy students must apply the relevant information learned in their academic and clinical experience to problem solve in treating patients. I compared the clinical cognitive competence in patient care of second-year masters students enrolled in two different curricular programs: modified problem-based (M P-B; n = 27) and subject-centered (S-C; n = 41). Main features of S-C learning include lecture and demonstration as the major teaching strategies and no exposure to patients or problem solving learning until the sciences (knowledge) have been taught. Comparatively, main features of M P-B learning include case study in small student groups as the main teaching strategy, early and frequent exposure to patients, and knowledge and problem solving skills learned together for each specific case. Basic and clinical orthopedic knowledge was measured with a written test with open-ended items. Problem solving skills were measured with a written case study patient problem test yielding three subscores: assessment, problem identification, and treatment planning. ^ Results indicated that among the demographic and educational characteristics analyzed, there was a significant difference between groups on ethnicity, bachelor degree type, admission GPA, and current GPA, but there was no significant difference on gender, age, possession of a physical therapy assistant license, and GRE score. In addition, the M P-B group achieved a significantly higher adjusted mean score on the orthopedic knowledge test after controlling for GRE scores. The S-C group achieved a significantly higher adjusted mean total score and treatment management subscore on the case study test after controlling for orthopedic knowledge test scores. These findings did not support their respective research hypotheses. There was no significant difference between groups on the assessment and problem identification subscores of the case study test. The integrated M P-B approach promoted superior retention of basic and clinical science knowledge. The results on problem solving skills were mixed. The S-C approach facilitated superior treatment planning skills, but equivalent patient assessment and problem identification skills by emphasizing all equally and exposing the students to more patients with a wider variety of orthopedic physical therapy needs than in the M P-B approach. ^

Perceptions of collaboration between emergency nurses and paramedics

Collaboration between emergency room (ER) nurses and paramedics is vital due to the increasing number of critically ill patients entering the hospital via the "911" system. This descriptive study examined the perception of the collaborative relationship using the Revised Pehl Collaboration Scale (RPCS) and by qualitative data from four free response questions. The results of this study indicated that the overall relationship between the ER nurses and paramedics was friendly but not fully trusting. The content analysis of the free response questions identified that the "report" of patient information was the origin the most conflict. The nurses felt that paramedic patient assessment, patient priorities, and by-pass protocol were problems. Whereas, the paramedics identified the nurses condescending manner and mistrust, not being "listened" to, and overcrowded emergency rooms as the source of conflict. Data was not statistically significant with regards to personal attributes or social demographics from the RPCS.

Clean Cookstoves and Health in Samlout, Cambodia

This paper discusses results from a study of the use of cleaner cooking solutions and general health status of people in rural areas from the Battambang province of Cambodia. Data collection included 372 demographic, health and socio-economic surveys with households living in 6 villages in the Samlout district, general health examinations, and measurements of stove use and household concentrations of PM 2.5. The data reveal that health in this population is a major concern, with a very high prevalence of reported abdominal pain, nausea, chronic cough, chest pains, and fever during examinations.  At the household level, we find that clean stove ownership is significantly correlated with the educational status of household head and socio-economic status of a household. Respondents from households with clean stoves appear less likely (though not statistically significantly so) to report household individuals having health problems such as occasional cough, high blood pressure and tuberculosis. Concentrations of PM2.5 are positively correlated with prevalence of occasional cough, high blood pressure and tuberculosis. Based on these results, we advise field testing and evaluation of targeted health interventions in these villages to address the numerous concerns of the local population, including exploring the potential role of clean stoves.

A 'before and after' study of nursing students' self-assessed competence in identifying the needs of older patients in hospital using an educational workbook.

Background: A core component of nurse education is clinical practice in order to support the development of clinical skills and competence. Assessment and measurement of the clinical competence of nursing students is important to gauge their professional development and educational needs.

Aim: To evaluate the impact of an Older Persons’ Assessment Educational Workbook (OPAEW) and explore second year nursing students’ competence and their opinions and use of the workbook.

Methods: A ‘before and after’ pre-experimental design was undertaken with n=6 second year nursing students. Outcome measures were the Nursing Competencies Questionnaire and the Self-efficacy in Clinical Performance Scale. Content analysis of workbooks and a survey (n=5) of opinions regarding the workbook was undertaken.

Findings: Pre and post test results for the study (n=5) were tested to determine if there was a relationship between changes in the NCQ and SECP repeated measures and use of an OPAEW. Testing identified evidence of a statistically significant difference for both SECP measures (SECP28 p=0.043; SECP7 p=0.042), with no clear statistical evidence of a difference for the NCQ (p=0.08). A weak negative association (NCQ ρ=-0.600 p=0.285; SECP28 ρ=-0.300 p=0.624; SECP7 ρ=-0.205 p=0.741), was found indicating that those participants who scored the lowest scores at the start of the study, benefited most from the workbook.

Content analysis of the OPAEW (n=5) found that 3 of the 5 participants completed all components of the workbook, with a mean of 1051 words used (SD 281.8). Through the survey (n=5) students reported the workbook as a useful guide when undertaking a patient assessment.

Conclusions: The OPAEW showed potential as an intervention to support the development of nursing students’ competence in older person assessment skills.

Multicystic nephroma in an elderly man. Case report

Multicystic nephroma is a relatively rare tumor of the kidney presenting unclear histological origin. Abdominal mass is a common onset sign in children while abdominal flank pain or abdominal discomfort, hematuria and recurrent urinary tract infections usually affect adults. Preoperative diagnosis is impossible especially in the adult variant of the tumor where clear cells carcinoma with cystic degeneration must always be suspected. We herein report a case of a 77 year old man complaining of flank abdominal pain and recurrent episodes of urinary tract infection due to a right-sided multicystic nephroma successfully treated with nephrectomy.

Severity in biliary peritonitis

Objective. To analyze clinical and laboratory findings in order to find variables predictive of severity of Biliary Peritonitis (BP). Patients and methods. Physical findings, course of illness, imaging and laboratory data were evaluated in 42 patients with BP, and statistically analysed to assess their prognostic significance. Results. Serious illness and worse outcome were associated with: age ≥ 60 years (P=0.034), long time between onset of symptoms and treatment (P=0.025), fever > 38°C (P=0.009), WBC count > 17,000 cell/mm³ (P=0.043), diffuse abdominal pain (P=0.034), and infected bile (P=0.048). Conclusions. Most patients become severely ill due to supervening infection, while early bile drainage avoids serious complications. In addition, abdominal pain, fever and WBC count are also predictive of severity of BP.

Primary Melanoma of the Small Intestine with a Metastatic Lymph Mass in the Inguinal Canal: A Case Report

Objectives: We report a case of primary melanoma of the small intestine. Primary intestinal melanoma (PIM) is an extremely rare neoplasm for which the cause is unknown. Materials and methods: A 67-year-old man was admitted to our department due to abdominal pain, constipation, a large, hard inguinal mass and severe anaemia. Results: After laboratory data, imaging techniques and histopathological examination, the diagnosis was confirmed. A surgical resection of the intestinal neoplasm, treatment with BRAF inhibitors and radiation therapy to the inguinal mass were performed. Conclusion: PIM is rare and it is usually difficult to establish its exact origin.

Spondylodiscitis as Complication of Transrectal Ultrasonography-guided Prostate Biopsy: a Case Report

A 61-year-old man presented with high fever, and severe back and abdominal pain following transrectal ultrasonography (TRUS)-guided prostate biopsy. Diagnosis of spondylodiscitis and psoas abscesses was made based on MRI images of the lumbar tract of the spine. Six-month broad-spectrum antibiotic treatment and immobilization with a girdle overcame the disease without any relapse at the 1-year follow-up. Spondylodiscitis after TRUS-guided prostate biopsy is a rare event, which is not yet included as a major complication of the procedure. It is probably due to the presence of fluoroquinolone-resistant bacteria in faeces. It is, therefore, important to highlight this possibility and to stress the use of targeted antibiotic prophylaxis after rectal flora swabbing with selected antibiotics at sufficient concentrations to be effective.

Delayed Bleeding after Percutaneous Liver Biopsy

Percutaneous liver biopsy (PLB) is a common procedure in patients with liver disease. Bleeding after PLB is rare, with an incidence of 0.35%. Most bleeding complications present within 24 h after biopsy. A 56-year-old woman was admitted to our hospital due to severe and sudden right upper quadrant (RUQ) abdominal pain 10 days after ultrasound (US)-guided PLB. CT study revealed both intrahepatic and intraperitoneal bleeding, and Hb levels decreased by 3.2 g/dl within a few hours. Such a prolonged delay in PLB-related bleeding has not been previously described in the medical literature.
