Soil physical properties and grape yield influenced by cover crops and management systems

The use of cover crops in vineyards is a conservation practice with the purpose of reducing soil erosion and improving the soil physical quality. The objective of this study was to evaluate cover crop species and management systems on soil physical properties and grape yield. The experiment was carried out in Bento Gonçalves, RS, Southern Brazil, on a Haplic Cambisol, in a vineyard established in 1989, using White and Rose Niagara grape (Vitis labrusca L.) in a horizontal, overhead trellis system. The treatments were established in 2002, consisting of three cover crops: spontaneous species (SS), black oat (Avena strigosa Schreb) (BO), and a mixture of white clover (Trifolium repens L.), red clover (Trifolium pratense L.) and annual rye-grass (Lolium multiflorum L.) (MC). Two management systems were applied: desiccation with herbicide (D) and mechanical mowing (M). Soil under a native forest (NF) area was collected as a reference. The experimental design consisted of completely randomized blocks, with three replications. The soil physical properties in the vine rows were not influenced by cover crops and were similar to the native forest, with good quality of the soil structure. In the inter-rows, however, there was a reduction in biopores, macroporosity, total porosity and an increase in soil density, related to the compaction of the surface soil layer. The M system increased soil aggregate stability compared to the D system. The treatments affected grapevine yield only in years with excess or irregular rainfall.

Prevalence and management of cardiovascular risk factors in Portuguese residents and Portuguese who migrated to Switzerland

Background: there is little information regarding the health status of migrants compared to subjects who remained in their country of origin. The aim was to compare Portuguese living in Porto (Portugal) with Portuguese migrants living in Lausanne (Switzerland). Design: cross-sectional studies conducted in Porto (EpiPorto, n=1150) and Lausanne (CoLaus, n=388) among Portuguese subjects aged between 35 and 65 years. Methods: body mass index, blood pressure, cholesterol and glucose levels were assessed using standardized procedures. Educational level, antihypertensive, hypocholesterolemic and antidiabetic treatments were collected using questionnaires. Results: Portuguese living in Lausanne were younger, more frequently male and had a lower education than Portuguese living in Porto. After multivariate adjustment, Portuguese living in Porto had a higher likelihood of being obese [Odds ratio and 95% confidence interval: 1.40 (1.01-1.94)] or abdominal obese [OR: 1.40 (1.02-1.93)] than Portuguese living in Lausanne. Portuguese living in Porto had a higher likelihood of being hypertensive than Portuguese living in Lausanne [OR: 1.38 (1.01-1.90)], while no differences were found regarding hypertension management and control. Portuguese living in Porto had a higher likelihood of being hypercholesterolemic [OR: 1.40 (1.06-1.85)] and were less likely to be treated [OR: 0.47 (0.27-0.83)] and controlled [OR: 0.47 (0.27-0.83)] than Portuguese living in Lausanne. Finally, no differences were found regarding smoking, prevalence and management of diabetes. Conclusion: Portuguese living in Lausanne, Switzerland, present a better cardiovascular risk profile and tend to be better managed regarding their cardiovascular risk factors than Portuguese living in Porto, Portugal.

Duodénopancréatectomie céphalique: indications, résultats et prise en charge des complications [Pancreaticoduodenectomy: indications, results and management of complications]

Pancreaticoduodenectomy is a major procedure in visceral surgery. Post-operative mortality is around 5% in high-volume hospitals, thanks to improvement in global patients care. Morbidity remains high though. The treatment of complications most often require a multidisciplinary approach. Delayed gastric emptying, intraabdominal abscesses and pancreatic fistulas are the most frequent complications. Post-pancreatectomy hemorrhage, although more rare, is a severe and dreadful event. Despite its morbidity, duodenopancreatectomy significantly improves survival of patients with biliopancreatic cancer. Early recognition of these complications and a prompt treatment increase the safety of this procedure.

ESCMID* guideline for the diagnosis and management of Candida diseases 2012: patients with HIV infection or AIDS.

Mucosal candidiasis is frequent in immunocompromised HIV-infected highly active antiretroviral (HAART) naive patients or those who have failed therapy. Mucosal candidiasis is a marker of progressive immune deficiency. Because of the frequently marked and prompt immune reconstitution induced by HAART, there is no recommendation for primary antifungal prophylaxis of mucosal candidiasis in the HIV setting in Europe, although it has been evidenced as effective in the pre-HAART era. Fluconazole remains the first line of therapy for both oropharyngeal candidiasis and oesophageal candidiasis and should be preferred to itraconazole oral solution (or capsules when not available) due to fewer side effects. For patients who still present with fluconazole-refractory mucosal candidiasis, oral treatment with any other azole should be preferred based on precise Candida species identification and susceptibility testing results in addition to the optimization of HAART when feasible. For vaginal candidiasis, topical therapy is preferred.

Chest pain in daily practice: occurrence, causes and management

QUESTIONS UNDER STUDY: We assessed the occurrence and aetiology of chest pain in primary care practice. These features differ between primary and emergency care settings, where most previous studies have been performed. METHODS: 59 GPs in western Switzerland recorded all consecutive cases presenting with chest pain. Clinical characteristics, laboratory tests and other investigations as well as the diagnoses remaining after 12 months of follow-up were systematically registered. RESULTS: Among 24,620 patients examined during a total duration of 300 weeks of observation, 672 (2.7%) presented with chest pain (52% female, mean age 55 +/- 19(SD)). Most cases, 442 (1.8%), presented new symptoms and in 356 (1.4%) it was the reason for consulting. Over 40 ailments were diagnosed: musculoskeletal chest pain (including chest wall syndrome) (49%), cardiovascular (16%), psychogenic (11%), respiratory (10%), digestive (8%), miscellaneous (2%) and without diagnosis (3%). The three most prevalent diseases were: chest wall syndrome (43%), coronary artery disease (12%) and anxiety (7%). Unstable angina (6), myocardial infarction (4) and pulmonary embolism (2) were uncommon (1.8%). Potentially serious conditions including cardiac, respiratory and neoplasic diseases accounted for 20% of cases. A large number of laboratory tests (42%), referral to a specialist (16%) or hospitalisation (5%) were performed. Twentyfive patients died during follow-up, of which twelve were for a reason directly associated with thoracic pain [cancer (7) and cardiac causes (5)]. CONCLUSIONS: Thoracic pain was present in 2.7% of primary care consultations. Chest wall syndrome pain was the main aetiology. Cardio - vascular emergencies were uncommon. However chest pain deserves full consideration because of the occurrence of potentially serious conditions.

Ätiologie und Management der Gicht [The etiology and management of gout].

Gout is an inflammatory arthritis caused by monosodium urate (MSU) crystal deposits in and around the joint. The formation of urinary calculi can also occur in gout, but are less common than arthritis. Gout usually presents with recurrent episodes of joint inflammation, which over time lead to tophus formation and joint destruction. In the last decade, significant advances have been made regarding not only the epidemiology and genetics of gout and hyperuricemia but also the mechanisms of inflammation and treatment of gout. In addition, knowledge concerning the key role of interleukin 1 (IL-1) has provided new therapeutic perspectives. However, the current management of gout is often suboptimal, with many Patienten either not receiving adequate treatment or being unable to tolerate existing treatments. New therapeutic agents provide interesting new options for Patienten with difficult-to-treat gouty arthritis.The English full-text version of this is available at SpringerLink (under "Supplemental").

Cutaneous benign mixed tumor (chondroid syringoma) of the eyelid: clinical presentation and management.

PURPOSE: To describe the clinical presentation of cutaneous benign mixed tumor of the eyelid and its management options. METHODS: Periocular cases of cutaneous benign mixed tumor were gathered from members of an oculoplastics specialty Internet discussion group. A total of 9 patients are described in this retrospective, interventional case series. The clinical presentation, histopathology, and management of these lesions is reviewed. RESULTS: Patients were typically asymptomatic, presenting with a slowly enlarging, nontender nodule of 2 to 8 years' duration. The lesions ranged from 4 mm to 17 mm in greatest dimension. Four of the lesions were on the eyelid margin, three in the sub-brow area of the upper eyelid, and two in the central lids. All six cases not involving the brow were fixed to the tarsus; one brow lesion was believed to be adherent to the skin. None of the lesions was associated with significant changes of the overlying epidermis, although one lesion showed overlying pigmentation. All patients underwent excisional biopsy for diagnostic or cosmetic reasons. On histopathologic examination, the tumors were biphasic, with an epithelial component exhibiting apocrine or hair follicle differentiation and a myxoid, adipocytic, chondroid, and/or fibrous stroma. The pathologic diagnoses were all consistent with cutaneous benign mixed tumor (chondroid syringoma, pleomorphic adenoma). Follow-up ranged from 2 weeks to 12 months, although several patients failed to keep scheduled follow-up appointments. No clinical recurrences were identified. CONCLUSIONS: Cutaneous benign mixed tumor may occur in the eyelid, and, although uncommon, should be included in the differential diagnosis of firm, nodular eyelid tumors. The histopathologic features are similar to those seen in this tumor type arising in other areas of the body. Preoperative consideration of this diagnostic possibility may allow the surgeon to plan for complete excision, thereby reducing the possibility of recurrence or malignant transformation.

The statistical accuracy of surveys on business and economic perspectives: a case study

In this paper, we develop a new decision making model and apply it in political Surveys of economic climate collect opinions of managers about the short-term future evolution of their business. Interviews are carried out on a regular basis and responses measure optimistic, neutral or pessimistic views about the economic perspectives. We propose a method to evaluate the sampling error of the average opinion derived from a particular type of survey data. Our variance estimate is useful to interpret historical trends and to decide whether changes in the index from one period to another are due to a structural change or whether ups and downs can be attributed to sampling randomness. An illustration using real data from a survey of business managers opinions is discussed.

Réplication cérébrale du VIH malgré une thérapie antirétrovirale efficace: impact clinique et prise en charge [Intracerebral HIV replication despite an efficient antiretroviral treatment: clinical impact and management].

Various neurological and neuropsychological manifestations are still relatively frequently reported in HIV infected patients in the highly active antiretroviral therapy era. A fraction of them could be related to HIV replication in the central nervous system (CNS) despite adequate peripheral viral suppression. This hypothesis is supported by numerous reports of detectable HIV RNA in the cerebrospinal fluid in the context of a low or undetectable viremia in association with neurological or neuropsychological complaints. In addition, some antiviral molecules may not achieve adequate levels in the CNS, thus potentially favoring intracerebral HIV replication and even antiretroviral resistance. Neurologic manifestations in the presence of CNS HIV replication often decrease after antiretroviral treatment CNS penetration optimization.
