RESUMEN

BACKGROUND: Cancer patients often use complementary and alternative medicine (CAM), however, standardized assessment in clinical routine is missing. The aim of this study was to evaluate a screening questionnaire on CAM usage that was published in the S3 Guideline Complementary Medicine in the Treatment of Oncological Patients. METHODS: We developed a survey questionnaire to assess the practicability of the guideline questionnaire and communication on CAM between health care providers (HCPs) and patients. We collected 258 guideline questionnaires and 116 survey questionnaires from ten clinics and held twelve semi-structured interviews with HCPs. RESULTS: 85% used at least one of the listed CAM methods, 54 participants (N = 77) never disclosed usage to a physician. The most frequently used CAM methods were physical activity (76.4%) and vitamin D (46.4%). 25.2% used at least one method, that was labeled risky by the guideline. 53.4% did not know of CAM's risk of interactions and side effects. Introducing the guideline questionnaire in routine cancer care increased the rate of patients talking to an HCP regarding CAM significantly from 35.5 to 87.3%. The HCPs stated positive effects as an initiation of conversation, increased safety within CAM usage and patients feeling thankful and taken seriously. However, due to the limited amount of time available for discussions on CAM, generalized distribution to all patients was not feasible. CONCLUSION: Institutions should focus on implementing standard procedures and resources that help HCPs discuss CAM on a regular basis. HCPs should meet the patient's demands for CAM counseling and make sure they are equipped professionally.

RESUMEN

PURPOSE: This trial investigates the addition of panitumumab to chemotherapy with fluorouracil/folinic acid and oxaliplatin (FOLFOX) in a 2:1 randomised, controlled, open-label, phase II trial in RAS wild-type colorectal cancer patients with R0/1-resected liver metastases. EXPERIMENTAL DESIGN: The primary endpoint was progression-free survival (PFS) two years after randomisation. The experimental arm (12 weeks of biweekly mFOLFOX6 plus panitumumab followed by 12 weeks of panitumumab alone) was considered active if the two-year PFS rate was ≥65%. Based on historical data, a two-year PFS rate of 50% was estimated in the control arm (12 weeks of biweekly FOLFOX). The trial was performed with a power of 80% and an alpha of 0.05. Secondary endpoints included overall survival (OS) and toxicity. The trial is registered with ClinicalTrials.gov, NCT01384994. RESULTS: The full analysis set consists of 70 patients (pts) in the experimental arm and 36 pts in the control arm. The primary endpoint was missed with a two-year PFS of 35.7% with FOLFOX plus panitumumab and 30.6% in the control arm. In comparative analyses, trends towards improved PFS (HR 0.83; 95%CI, 0.52-1.33; P = 0.44) and OS (HR 0.70; 95% CI, 0.34-1.46; P = 0.34) were observed in favour of the panitumumab-based study arm. No new or unexpected safety signals were observed with FOLFOX plus panitumumab following liver resection. CONCLUSION: The PARLIM trial failed to demonstrate a two-year PFS rate of 65% after resection of colorectal liver metastases. The positive trends in survival endpoints may support future trials evaluating treatment with anti-EGFR agents after resection of liver metastases.

RESUMEN

Anxiety is an adaptive emotional response to potentially threatening or dangerous situations; moderated by the sympathetic nervous system. Dental anxiety is common and presents before, during or after dental treatment. The physiological response includes an increase in heart rate, blood pressure, respiratory rate, and cardiac output. Consequently, extensive distress leads to avoidance of dental treatment and multiple failed appointments, impacting both oral and general health. Dental anxiety can generate a variety of negative consequences for both the dentist and the patient. Evidence-based strategies are essential for mitigating and relieving anxiety in the dental clinic. Psychotherapeutic behavioural strategies can modify the patient's experience through a minimally invasive approach with nil or negligible side effects, depending on patient characteristics, anxiety level and clinical situations. These therapies involve muscle relaxation, guided imagery, physiological monitoring, utilizing biofeedback, hypnosis, acupuncture, distraction and desensitization. Pharmacological intervention utilizes either relative analgesia (nitrous oxide), conscious intravenous sedation or oral sedation, which can have undesirable side effects, risks and contraindications. These modalities increase the cost and availability of dental treatment.

RESUMEN

Plant extracts have been recognized as beneficial to human health and have been evaluated as feed additive for domestic and companion animals. This study evaluated oregano and green tea extracts fed to Jersey cows from approximately 21 d before calving to 21 d after calving on milk production, milk composition, and blood metabolites as well as investigated immunological and antioxidant attributes. Twenty-four Jersey cows with 441 ±â€¯27 kg of BW, 3.5 ±â€¯0.3 of body condition score (BCS), and 2.7 ±â€¯1.8 lactations were selected at approximately 28 d before the expected parturition date and were randomly assigned to three treatments with eight cows each: without plant extracts in diet (control - CON), addition of 10 g per day of oregano extract (OR), and addition of 5 g per day of green tea extract (GT). Feed intake, BW, BCS, blood metabolites, hemogram as well as oxidative stress biomarkers were evaluated from approximately 3 weeks prepartum to 3 weeks postpartum (transition period) while milk production and composition were evaluated during the first 3 weeks of lactation. Plant extracts did not change BW, BCS, and DM intake (DMI) throughout the transition period, but OR increased in approximately 20% total digestive nutrients and metabolizable energy intake on days 15 and 16 postpartum compared with CON. In the prepartum, OR increased in 48% platelets count compared to the CON, while GT augmented in 142% eosinophils compared with CON. Oregano extract reduced the levels of reactive species in the erythrocytes in 40% during prepartum and postpartum compared with CON, while GT reduced its levels in 24 and 29% during prepartum and postpartum, respectively, when compared with CON. In the postpartum period, OR increased in 60% the carbonylated protein content compared with CON, while GT reduced in 45% the levels of reactive species in plasma compared with CON. During the postpartum, both extracts increased in 33% the concentration of reduced glutathione when compared with CON. Moreover, GT tended to decrease feed efficiency in 11% when compared with CON; OE reduced milk pH and somatic cell count when compared with CON. In conclusion, OE and GT did not expressively affect immunological attributes in blood but reduce some oxidative stress biomarkers without compromising productive traits of Jersey cows during the transition period.

RESUMEN

Calcium and vitamin D are essential for maintaining bone health. Therefore, deficiencies in calcium and vitamin D are major risk factors for osteoporosis development. Because sufficient amounts of calcium are also required for fracture-callus mineralisation, compromised bone repair that is frequently observed in osteoporotic patients might be attributed to calcium and vitamin D deficiencies. Consequently, calcium and vitamin D supplementation represents a potential strategy for treating compromised fracture healing in osteoporotic patients. Growing clinical evidence suggests that a fracture event may induce post-traumatic bone loss in the non-fractured skeleton, particularly in osteoporotic patients, which might further exacerbate osteoporosis and increase the risk of secondary fractures. Because the skeleton represents the main source of calcium, which is increasingly required during fracture-callus mineralisation, post-traumatic calcium mobilisation might occur under conditions of insufficient calcium and vitamin D status. However, to date, investigations of the roles of calcium and vitamin D in bone repair and post-traumatic bone turnover are very limited. The current review summarises the state of the literature, focusing on the role of calcium and vitamin D in fracture healing and post-traumatic bone turnover, and critically discusses the therapeutic potential of calcium and vitamin D supplementation in this context.

RESUMEN

Plant extracts have been proposed as substitutes for chemical feed additives due to their potential as rumen fermentation modifiers and because of their antimicrobial and antioxidant activities, possibly reducing methane emissions. This study aimed to evaluate the use of oregano (OR), green tea extracts (GT), and their association as feed additives on the performance and methane emissions from dairy between 28 and 87 d of lactation. Thirty-two lactating dairy cows, blocked into 2 genetic groups: 16 Holstein cows and 16 crossbred Holstein-Gir, with 522.6 ± 58.3 kg of body weight, 57.2 ± 20.9 d in lactation, producing 27.5 ± 5.0 kg/cow of milk and with 3.1 ± 1.8 lactations were evaluated (means ± standard error of the means). Cows were allocated into 4 treatments: control (CON), without plant extracts in the diet; oregano extract (OR), with the addition of 0.056% of oregano extract in the dry matter (DM) of the diet; green tea (GT), with the addition of 0.028% of green tea extract in the DM of the diet; and mixture, with the addition of 0.056% oregano extract and 0.028% green tea extract in the DM of the diet. The forage-to-concentrate ratio was 60:40. Forage was composed of corn silage (94%) and Tifton hay (6%); concentrate was based on ground corn and soybean meal. Plant extracts were supplied as powder, which was previously added and homogenized into 1 kg of concentrate in natural matter, top-dressed onto the total mixed diet. No treatment by day interaction was observed for any of the evaluated variables, but some block by treatment interactions were significant. In Holstein cows, the mixture treatment decreased gross energy and tended to decrease the total-tract apparent digestibility coefficient for crude protein and total digestible nutrients when compared with OR. During the gas measurement period, GT and OR increased the digestible fraction of the ingested DM and decreased CH4 expressed in grams per kilogram of digestible DMI compared with CON. The use of extracts did not change rumen pH, total volatile fatty acid concentration, milk yield, or most milk traits. Compared with CON, oregano addition decreased fat concentration in milk. The use of plant extracts altered some milk fatty acids but did not change milk fatty acids grouped according to chain length (short or long), saturation (unsaturated or saturated), total conjugated linoleic acids, and n-3 and n-6 contents. Green tea and oregano fed separately reduced gas emission in cows during the first third of lactation and have potential to be used as feed additives for dairy cows.

RESUMEN

Avaliaram-se o efeito da suplementação de selênio, na dieta ofertada aos animais, sobre a concentração do mineral no sangue e no leite e as alterações nas características físico-químicas, contagem de células somáticas (CCS) e produção de leite. O experimento durou 63 dias, dos quais os primeiros 21 foram pré-experimental. Foram utilizadas 32 vacas em lactação da raça Jersey, as quais apresentavam, ao início, peso corporal de 402,5+58,4kg, escore de condição corporal de 3,19+0,31, produção de leite de 10,4+2,1kg e número de dias em lactação de 141,4+69,3. Os tratamentos foram: sem suplementação (grupo-controle); com suplementação de selênio inorgânico 0,3 (dieta-padrão + 0,3mg selenito de sódio/kg de concentrado - SI0,3); com suplementação com selênio orgânico 0,3 (dieta-padrão + 0,3mg seleniometionina/kg de concentrado - SO0,3) e com suplementação de selênio orgânico 0,6 (dieta-padrão + 0,6mg seleniometionina/kg de concentrado - SO0,6). As quantidades totais de selênio das dietas foram, respectivamente, 2,38; 4,18; 4,18 e 5,98mg/dia para os tratamentos controle, SI0,3, SO0,3 e SO0,6. O delineamento experimental foi o completamente ao acaso. O número de dias em lactação e os valores obtidos no início do experimento foram usados como covariáveis. Foram realizadas avaliações da produção de leite, do peso, da condição corporal, da composição do leite e do sangue nos dias 0, 14, 28 e 42 do período experimental. Entre os tratamentos, não foram detectadas alterações quanto à produção de leite, peso, condição corporal, características físico-químicas e microbiológicas do leite, e perfil bioquímico do sangue, exceto em relação à concentração de selênio no sangue entre o tratamento-controle e os tratamentos suplementados. Não houve diferenças quanto aos teores de selênio no sangue entre as fontes de selênio e as doses. Os teores de selênio no sangue evoluíram distintamente durante o experimento conforme a dose e a fonte. A suplementação com selênio ...


The effects of the dietary supplementation with selenium were evaluated on the concentration of the mineral in blood and milk, as well as changes in milk yield, physical and chemical characteristics, and somatic cells count (SCC). The trial lasted 63 days, the first 21 were designed to adaptation of animals to experimental conditions and standard diet. Thirty-two lactating Jersey cows were used and, at the beginning of the trial, they presented body weight of 402.5+58.4kg, body condition score of 3.19+0.31, milk yield of 10.4+2.1kg/day, and 141.4+69.3 days in milking. Treatments were: control (standard diet without added selenium), inorganic selenium (standard diet + 0.3mg sodium selenite/kg concentrate - SI0.3), organic selenium 0.3 (standard diet + 0.3mg selenomethionine/kg concentrate - SO0.3), and organic selenium 0.6 (standard diet + 0.6mg selenomethionine/kg concentrate - SO0.6). Total daily amounts of selenium were 2.38, 4.18, 4.18, and 5.98mg/cow, respectively, for control, SI0.3, SO0.3, and SO0.6 treatments. The trial was conducted as a completely randomized design. The number of days in milking and the values for all attributes measured at the end of the adaptation period were used as covariates. Measurements of body weight and condition score, milk yield and composition, and blood composition were performed on days 0, 14, 28, and 42 of the experimental period. No differences were detected among treatments for milk yield and composition, body weight and condition score, physical-chemical characteristics of milk, somatic cells count, and biochemical profile of the blood, except for Se contents of blood of control compared to supplemented. There were no differences caused by selenium sources or levels. Selenium supplementation did not alter neither milk nor blood components.

RESUMEN

A consistent group of progressive central and peripheral nervous system lesions developed in seven rhesus monkeys maintained on a vitamin E-deficient diet for 30 to 33 months. These lesions were absent from vitamin E-supplemented monkeys. The principal neuropathologic alteration was loss of sensory axons in the posterior columns, sensory roots, and peripheral nerves. Morphologic and morphometric studies indicated that the distal segments of the axons were affected most severely and large-caliber myelinated fibers are selectively involved. Swollen, dystrophic axons (spheroids) occurred infrequently. Degeneration and phagocytosis of small numbers of neuronal perikarya were observed in the dorsal root ganglia and the anterior horns. The number of affected neurons was not proportional to the number of affected axons. Accumulation of lipopigment was evident in neuronal perikarya and CNS endothelial cells. The nervous system lesion were usually accompanied by a chronic necrotizing myopathy. The neuropathologic lesions in vitamin E-deficient monkeys are compared with those in vitamin E-deficient rats and in humans with low serum vitamin E concentrations. A similar type of sensory axonopathy is associated with chronic deficiency of vitamin E in these three species.
