Cancer treatment adherence among low-income women with breast or gynecologic cancer: a randomized controlled trial of patient navigation.

The authors implemented a controlled, randomized trial that compared 2 interventions: the provision of written resource navigation information (enhanced usual care [EUC]) versus written information plus patient navigation (TPN) aimed at improving adjuvant treatment adherence and follow-up among 487 low-income, predominantly Hispanic women with breast cancer or gynecologic cancer.



Women were randomized to receive either TPN or EUC; and chemotherapy, radiation therapy, hormone therapy, and follow-up were assessed over 12 months. Patients with breast cancer were analyzed separately from patients with gynecologic cancer.



Overall adherence rates ranged from 87% to 94%, and there were no significant differences between the TPN group and the EUC group. Among women with breast cancer, 90% of the EUC group and 88% of the TPN group completed chemotherapy (14% of the EUC group and 26% of the TPN group delayed the completion of chemotherapy), 2% of the EUC group and 4% of the TPN group failed to complete chemotherapy, and 8% of the EUC group and 7% of the TPN group refused chemotherapy. Radiation treatment adherence was similar between the groups: Ninety percent of patients completed radiation (40% of the EUC group and 42% of the TPN group delayed the completion of radiation); in both groups, 2% failed to complete radiation, and 8% refused radiation. Among gynecologic patients, 87% of the EUC group and 94% of the TPN group completed chemotherapy (41% of the EUC group and 31% of the TPN group completed it with delays), 7% of the EUC group and 6% of the TPN group failed to complete chemotherapy, 6% of the EUC refused chemotherapy, 87% of the EUC group and 84% of the TPN group completed radiation (51% of the EUC group and 42% of the TPN with delays), 5% of the EUC group and 8% of the TPN group failed to complete radiation, and 8% of the EUC group and 5% of the TPN group refused radiation.



Treatment adherence across randomized groups was notably higher than reported in previous studies, suggesting that active telephone patient navigation or written resource informational materials may facilitate adherence among low-income, predominantly Hispanic women. Adherence also may have be facilitated by federal-state breast and cervical cancer treatment funding.
The influence of rotational exercises on freezing in Parkinson's disease.

The advanced stage of Parkinson's disease (PD) is characterised by complex movement disturbances including freezing. Because freezing is resistant to drug therapy, there has recently been renewed interest in non-pharmacological treatment programmes. In this study the effect of rotational stimulation on freezing was investigated. Eight patients with idiopathic PD and freezing participated in the study. Switching from foot-lifting to 'stand up and walk' provoked freezing in all the tested patients. The mean OPMSP (Onset of Premotor Silence Period) in the EMG of the m. tibialis anterior during the 'foot-lifting' sessions preceding freezing was 124 msec. This value, together with a striking repetition of the EMG discharges in the m. tibialis anterior following the request to 'stand up and walk', was related to the inducement of freezing, as a decrease of 42 msec in the OPMSP (t = 2.61; p < or = 0.01) after rotational stimulation abolished freezing and the concomitant EMG disturbances. Rotational stimulation also reduced freezing frequency during daily life. Freezing periods fell to below 50% of the pre-treatment level the day following rotation (t = 5.58; p < or = 0.001). The OPMSP predicted the short and long-term effects of rotational exercises (R = 0.74; p < or = 0.03). The rather long-lasting effect of the stimulation suggests a possible modulation of neurochemical transmission. Further studies are required to shed more light on the point of action and to elucidate which neurotransmitter might be involved.
Randomized clinical trial on Harmonic Focus shears versus clamp-and-tie technique for total thyroidectomy.

The Harmonic Focus is the last ultrasonic device designed for thyroid surgery. The aim is to assess its efficacy and safety compared with traditional dissection in a prospective randomized trial of total thyroidectomy procedures.



Total thyroidectomy was performed in 34 patients using the Harmonic Focus, and in 34 patients using the clamp-and-tie technique.



In the Harmonic Focus group, relative reductions of 29% and 46% were observed in surgical time and blood loss, respectively. The number of intraoperative instrument exchanges also decreased by 70%, and use of specific materials required to achieve hemostasis decreased significantly. Safety was found to be similar in both patient groups.



Our study showed beneficial effects of Harmonic Focus use in thyroid surgery. Further studies therefore are needed to evaluate cost in the light of savings made in surgical time, materials needed for hemostasis, and human resources.
Isometric quadriceps strength in women with mild, moderate, and severe knee osteoarthritis.

Quadriceps weakness is a common clinical sign in persons with moderate-to-severe osteoarthritis and results in physical disability; however, minimal data exist to establish whether quadriceps weakness is present in early stages of the disease. Therefore, our purpose was to determine whether quadriceps weakness was present in persons with early radiographic and cartilaginous evidence of osteoarthritis. Further, we sought to determine whether quadriceps strength decreases as osteoarthritis severity increases.



Three hundred forty-eight women completed radiologic and magnetic resonance imaging evaluation, in addition to strength testing. Anterior-posterior radiographs were graded for tibiofemoral osteoarthritis severity using the Kellgren-Lawrence scale. Scans from magnetic resonance imaging were used to assess medial tibiofemoral and patellar cartilage based on a modification of the Noyes scale. The peak knee extension torque recorded was used to represent strength.



Quadriceps strength (Nm/kg) was 22% greater in women without radiographic osteoarthritis than in women with osteoarthritis (P < 0.05). Quadriceps strength was also greater in women with Noyes' medial tibial and femoral cartilage scores of 0 when compared in women with Noyes' grades 2 and 3-5 (P < or = 0.05).



Women with early evidence of osteoarthritis had less quadriceps strength than women without osteoarthritis as defined by imaging.
Post-bronchiolitis Use of Asthma Medication: A Prospective 1-year Follow-up Study.

Our aim was to evaluate the association between viral findings during bronchiolitis and the use of asthma controller medication (primary outcome) and systemic corticosteroids (secondary outcome) during the first post-bronchiolitis year.



We enrolled 408 children hospitalized for bronchiolitis at <24 months of age in a prospective, 3-center, 1-year follow-up study in Finland. Viruses were detected with polymerase chain reaction in nasopharyngeal aspirates. The parents underwent a structured interview during hospitalization. Twelve months later, the use of asthma medication was asked in a structured questionnaire. Multivariable logistic regression was used for statistical analysis.



In total, 365 (89%) children completed the 1-year follow-up. The use of long-term asthma controller medication was highest in the rhinovirus-positive group (61% vs. 15% in respiratory syncytial virus-positive group; adjusted odd ratios, 7.5; 95% confidence interval: 3.7-15.3), followed by children negative for both respiratory syncytial virus and rhinovirus (36%; adjusted odd ratios, 2.6; 95% confidence interval: 1.3-5.3). Likewise, rhinovirus etiology was associated with more courses of systemic corticosteroids during the follow-up. The main findings were similar in a subset of infants aged <12 months with first wheezing.



Children hospitalized for rhinovirus-positive bronchiolitis used long-term asthma controller medication more often than those hospitalized for rhinovirus-negative bronchiolitis during first year after hospitalization.
Radiofrequency catheter ablation versus balloon cryoablation of atrial fibrillation: markers of myocardial damage, inflammation, and thrombogenesis

Evidence from animal and human studies suggests that cryoablation might be associated with a lesser inflammatory response and activation of coagulation compared with radiofrequency ablation. The study was aimed at comparing the effect of cryoballoon and radiofrequency catheter ablation of paroxysmal atrial fibrillation on markers of myocardial damage, inflammation, and activation of coagulation. Forty-one patients received either cryoballoon (n = 23) or radiofrequency (n = 18) ablation of atrial fibrillation. We measured troponin I, high-sensitivity CRP, and interleukin 6 at baseline from the cubital vein, and from the right and left atrium before and after ablation, and from the cubital vein the following day. Prothrombin fragments 1 + 2, soluble P‑selectin, and D‑dimer were measured before and after ablation from both atria. We observed higher troponin I release in the cryoballoon than in the radiofrequency group (7.01 mcg/l (interquartile range [IQR]: 5.30–9.09) vs 2.32 mcg/l (IQR: 1.45–2.98), p < 0.001). The levels of inflammatory markers (high-sensitivity CRP and interleukin 6) in the two groups were comparable, as were the levels of markers of coagulation activation. Procedure duration, fluoroscopy times, and mid-term success (23 months, IQR 7–32) of the two groups were also comparable. Cryoballoon ablation of atrial fibrillation causes more significant myocardial damage, that is, more extensive ablation lesions, compared with radiofrequency catheter ablation. However, no major differences between these two ablation techniques with regard to the inflammatory response and activation of the coagulation system were observed.
Effect of selective beta-blockade with bisoprolol in the treatment of recent-onset atrial fibrillation.

The incidence of atrial fibrillation has been rapidly increasing in recent years. The increased tonus of the sympathetic nervous system is related to the development of atrial fibrillation.



TO study the effect of bisoprolol, a highly selective beta-blocker, on patients with recent-onset atrial fibrillation (< 48 hours) for regularization of the rhythm using propafenone.



The study includes 164 patients (81 women, 83 men, age 59.09 +/- 10.81) with successfully restored sinus rhythm in recent-onset atrial fibrillation. The patients received either propafenone (group A, n = 82) or a combination of propafenone and bisoprolol (group B, n = 82). The studied patients were randomly allocated to the groups. Propafenone was administered intravenously as a 2 mg/kg bolus followed by infusion of 0.0078 mg/kg/min for 120 min and orally in dosage of 300 mg three times every 8 hours if arrhythmia persisted. Bisoprolol was administered in a single dose at the very beginning of propafenone treatment and only in patients from group B at a dose of 5 or 10 mg. Regularization of the rhythm was assessed at the 3rd, 6th, 12th and 24th hour.



In the initial stages of regularization the combined therapy restored the sinus rhythm in a greater number of patients in comparison with the monotherapy (at the 6th hour 67.07% in group B versus 48.78% in group A, P < 0.05; at the 12th hour it was 87.80% versus 75.60%, respectively, P < 0.05).



Early regularization of rhythm in patients with recent-onset atrial fibrillation reduces the likelihood of recurrent episodes of arrhythmia. This makes the application of selective beta-blockade clinically significant.
Are Private Reserves Effective for Jaguar Conservation?

We present the first study of density and apparent survival for a jaguar (Panthera onca) population in northern Mexico using 13 years of camera trap data from 2000 to 2012. We used the Barker robust design model which combines data from closed sampling periods and resight data between these periods to estimate apparent survival and abundance. We identified 467 jaguar pictures that corresponded to 48 jaguar individuals. We included camera type and field technician as covariates for detection probabilities. We used three covariates to evaluate the effect of reserve on jaguar apparent survival: i) private reserve creation ii) later reserve expansions, and iii) cattle ranches' conservation activities. We found that the use of digital cameras in addition to film cameras increased detection probability by a factor of 6x compared with the use of only film cameras (p = 0.34 ± 0.05 and p = 0.05 ± 0.02 respectively) in the closed period and more than three times in the open period (R = 0.91 ± 0.08 and R = 0.30 ± 0.13 mixed and film cameras respectively). Our availability estimates showed no temporary emigration and a fidelity probability of 1. Despite an increase of apparent survival probability from 0.47 ± 0.15 to 0.56 ± 0.11 after 2007, no single covariate explained the change in these point estimates. Mean jaguar density was 1.87 ± 0.47 jaguars/100 km2. We found that 13 years of jaguar population monitoring with our sampling size were not enough for detecting changes in survival or density. Our results provide a baseline for studies evaluating the effectiveness of protected areas and the inclusion of ranch owners in jaguar conservation programs and long-term population viability.
Insulin concentrations and insulin sensitivity after short-term amiloride in healthy subjects

We have evaluated the short-term effects of amiloride on insulin action in vivo, since amiloride is known to impair insulin action in vitro. Seven healthy subjects were treated according to a randomized, double-blind, cross-over protocol. The treatment periods were 3 days each with amiloride 15 mg daily and placebo. Insulin action on glucose turnover was assessed directly after each treatment period with the hyper-insulinaemic euglycaemic glucose clamp technique. At the two insulin concentrations studied (∼ 30 mU·l−1 and ∼ 200 mU·l−1), the glucose infusion rate required to maintain constant euglycaemia did not differ after either amiloride or placebo. The rates of glucose production and utilization were also similar, whereas the so-called insulin sensitivity index at the lower insulin concentration was significantly reduced (by about 15 %) after amiloride. Moreover, amiloride produced significantly higher fasting insulin and C-peptide concentrations, whereas fasting glucose and NEFA concentrations were unaltered. In conclusion, these data suggest that short-term amiloride slightly impairs insulin sensitivity with respect to glucose uptake. However, overall glucose homoeostasis does not appear to be affected, probably due to a compensatory rise in plasma insulin.
Determinant Factors of the Direct Medical Costs Associated with Genotype 1 Hepatitis C Infection in Treatment-Experienced Patients

Limited evidence is available on predictors of medical resource utilization (MRU) and related direct costs, especially in treatment-experienced patients infected with genotype 1 hepatitis C virus (HCV). This study aimed at investigating patient and treatment characteristics that predict MRU and related non-drug costs in treatment-experienced patients with chronic hepatitis C (CHC) treated with simeprevir (SMV) or telapravir (TVR) in combination with pegylated interferon and ribavirin (PegIFN/R).



A total of 709 patients who completed the 72-week ATTAIN trial were included in the study. Cost data were analysed from the UK NHS perspective. Descriptive statistics and regression analyses were used to determine patterns and predictors of total MRU-related costs associated with SMV/PegIFN/R and TVR/PegIFN/R.



Independent predictors for total MRU-related costs were age, region and the following interaction terms: (1) gender × F3-F4 METAVIR score × baseline viral load (BLVL), (2) body mass index (BMI) × F3-F4 METAVIR score × prior response to PegIFN/R and (3) gender × achievement of SVR at 12 weeks (SVR12) × BLVL. A F3-F4 METAVIR score was a stronger predictor of total MRU-related costs than SVR12. Predictors of adverse events included older age, female gender, low BMI, TVR/PegIFN/R and SVR12. Wilcoxon rank sum test revealed comparable total MRU-related costs between SMV/PegIFN/R and TVR/PegIFN/R.



To the best of our knowledge, this study is the first to describe the relationship between commonly admitted predictors of MRU-related costs and their joint effect on total MRU-related costs in treatment-experienced patients with CHC. The identified predictors of MRU-related costs suggest that significant treatment costs can be avoided by starting treatment early before the disease progresses. Furthermore, adverse events seem to be the most important factor to take into consideration for the choice of treatment, especially when therapeutic options are associated with similar levels of medical resource utilization and associated costs.
Bone Mineral Density of the Spine, Hip and Distal Forearm in Representative Samples of the Japanese Female Population: Japanese Population-Based Osteoporosis (JPOS) Study

Low bone mineral density (BMD) is one of the most important elements for the diagnosis of osteoporosis and screening people with higher risk of fractures. To establish the criterion value of BMD for the diagnosis of osteoporosis and to estimate the prevalence rate of osteoporosis in Japanese women, we performed a Japanese population-based osteoporosis (JPOS) study. The subjects were 4550 women aged 15 through 79 years randomly selected from seven municipalities throughout Japan. The sample size was determined to ensure that the observed mean BMD would remain within 2.5% from the real value with a probability of 0.95 in each of the 5-year age groups. The study comprised bone mass measurements by dual-energy X-ray absorptiometry at the spine (L2–4), hip and distal forearm, body size measurements and detailed interviews on medical and gynecologic history. After excluding those subjects with apparent or suggested abnormalities affecting bone mass from 3985 women (87.6%) who completed the study, 3465 women remained and served as the subjects. We present 5-year age-specific mean values of BMD and cut-off values for the diagnosis of osteoporosis according to World Health Organization (WHO) and the Japanese Society of Bone and Mineral Research (JSBMR) criteria. The cut-off levels at the spine and the distal radius proposed in this study were similar to those proposed by the JSBMR but the cut-off level at the femoral neck in this study was 4.7% higher than that of the JSBMR. The prevalence rates of osteoporosis according to WHO criteria in the present subjects aged 50 through 79 years were calculated as 38.0% at the spine, 11.6% at the femoral neck and 56.8% at the distal one-third site of the radius, and those in the Japanese female population of the same age were estimated to be 35.1%, 9.4% and 51.2%, respectively. A fivefold difference was observed among the prevalence rates at different skeletal sites, which suggests that the different definitions of osteoporosis should be established for the different skeletal sites. The prevalence rate diagnosed at the femoral neck seemed to be lower in the present study than those reported for Caucasians. This might account for a lower incidence rate of hip fracture in Japanese women.
Cancer-related fatigue and rehabilitation: a randomized controlled multicenter trial comparing physical training combined with cognitive-behavioral therapy with physical training only and with no intervention.

Research suggests that cancer rehabilitation reduces fatigue in survivors of cancer. To date, it is unclear what type of rehabilitation is most beneficial.



This randomized controlled trial compared the effect on cancer-related fatigue of physical training combined with cognitive behavioral therapy with physical training alone and with no intervention.



In this multicenter randomized controlled trial, 147 survivors of cancer were randomly assigned to a group that received physical training combined with cognitive-behavioral therapy (PT+CBT group, n=76) or to a group that received physical training alone (PT group, n=71). In addition, a nonintervention control group (WLC group) consisting of 62 survivors of cancer who were on the waiting lists of rehabilitation centers elsewhere was included.



The study was conducted at 4 rehabilitation centers in the Netherlands.



All patients were survivors of cancer.



Physical training consisting of 2 hours of individual training and group sports took place twice weekly, and cognitive-behavioral therapy took place once weekly for 2 hours.



Fatigue was assessed with the Multidimensional Fatigue Inventory before and immediately after intervention (12 weeks after enrollment). The WLC group completed questionnaires at the same time points.



Baseline fatigue did not differ significantly among the 3 groups. Over time, levels of fatigue significantly decreased in all domains in all groups, except in mental fatigue in the WLC group. Analyses of variance of postintervention fatigue showed statistically significant group effects on general fatigue, on physical and mental fatigue, and on reduced activation but not on reduced motivation. Compared with the WLC group, the PT group reported significantly greater decline in 4 domains of fatigue, whereas the PT+CBT group reported significantly greater decline in physical fatigue only. No significant differences in decline in fatigue were found between the PT+CBT and PT groups.



Physical training combined with cognitive-behavioral therapy and physical training alone had significant and beneficial effects on fatigue compared with no intervention. Physical training was equally effective as or more effective than physical training combined with cognitive-behavioral therapy in reducing cancer-related fatigue, suggesting that cognitive-behavioral therapy did not have additional beneficial effects beyond the benefits of physical training.
