Objective: The aim was to retrieve and analyse the serious adverse events of venous occlusion systems used in cyanoacrylate adhesive closure (CAC) submitted to regulatory agencies. Methods: The Total Product Life Cycle (TPLC) database of the US Food and Drug Administration (FDA), the Database of Adverse Event Notifications (DAEN) of the Australian Therapeutic Goods Administration (TGA), and the Yellow Card database of the UK Medicines and Healthcare Products Regulatory Agency (MHRA) were reviewed. Three Freedom of Information (FOI) requests had to be submitted to the MHRA to obtain data. Results: The TPLC contained 899 reports which included 13 cases of death, 7 strokes, 211 thromboembolic events, and 482 immune reactions. The DAEN recorded three reportable adverse events, and the MHRA recorded seven adverse incidents including one death. Conclusion: CAC is associated with serious adverse events including death. These events are under-reported in the medical literature and only sub-optimally reported to the regulatory agencies. [ABSTRACT FROM AUTHOR]

Background: Radiolabeled antibody fragments present a promising opportunity as theranostic agents, offering distinct advantages over whole antibodies. In this study, the authors investigate the potential of [177Lu]Lu-DTPA-F(ab′)2-pertuzumab as a theranostic agent for precise targeting of human epidermal growth factor receptor 2 (HER2)-positive cancers. Additionally, the authors aim to quantitatively assess the binding synergism in the presence of cold trastuzumab. Materials and Methods: F(ab′)2-pertuzumab was prepared by pepsin digestion and conjugated with a bifunctional chelator. The immunoconjugate was radiolabeled with 177Lu and characterized by chromatography techniques. Binding parameters (affinity, specificity, and immunoreactivity) and cellular binding enhancement studies were evaluated in HER2-overexpressing and triple-negative cell lines. The in vivo enhancement in tumor uptake of the radiolabeled immunoformulation was assessed in severe combined immunodeficient (SCID) mice bearing tumors, both in the presence and absence of unlabeled trastuzumab. Results: The formulation of [177Lu]Lu-DTPA-F(ab′)2-pertuzumab could be prepared in high yields and with consistent radiochemical purity, ensuring reproducibility. Comprehensive in vitro and in vivo evaluation studies confirmed high specificity and immunoreactivity of the formulation toward HER2 receptors. Binding synergism of radiolabeled pertuzumab fragments in the presence of trastuzumab to HER2 receptors was observed. Conclusions: The radioformulation of [177Lu]Lu-DTPA-F(ab′)2-pertuzumab holds great promise as a targeted approach for addressing HER2-positive cancers. A potentially effective strategy to amplify therapeutic efficacy involves dual epitope targeting by combining radiolabeled pertuzumab with cold trastuzumab. [ABSTRACT FROM AUTHOR]

ABSTRACT This report was aimed at presenting a case of neurotrophic keratitis and concomitant SARS-CoV-2 infection in a patient who has recently undergone a corneal DALK transplant. One month after corneal transplantation with adequate corneal epithelialization, the patient presented neurotrophic keratitis with a torpid course of the corneal transplant coinciding with a SARS-CoV-2 infection, with an excessive host immune response. In addition, the patient presented a re-positivization of nasopharyngeal polymerase chain reaction of SARS-CoV-2 with past disease after starting treatment with autologous serum eye drops. The implications at the ophthalmological level of SARS-CoV-2 infection may be clarified as the time the illness progresses and we learn more about how it acts. In this case, the disparity of signs and symptoms, the antecedent of corneal surgery, and the possibility of a herpetic infection as a cause of the primary leukoma suggested neurotrophic keratitis. Nonetheless, the involvement of systemic SARS-CoV-2 infection in the process, triggering an excessive host immune response at the corneal level with an increase in inflammatory cytokines must be taken into account. No relationship was found between treatment with autologous serum and re-positivization of nasopharyngeal polymerase chain reaction, presenting the patient a favorable response to treatment.

BACKGROUND: Long COVID describes a condition with symptoms that linger for months to years following acute COVID-19. Many of these Long COVID symptoms are like those experienced by patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). OBJECTIVE: We wanted to determine if people with Long COVID experienced post-exertional malaise (PEM), the hallmark symptom of ME/CFS, and if so, how it compared to PEM experienced by patients with ME/CFS. METHODS: A questionnaire that asked about the domains of PEM including triggers, experience, recovery, and prevention was administered to 80 people seeking care for Long COVID at Bateman Horne Center. Their responses were compared to responses about PEM given by 151 patients with ME/CFS using chi-square tests of independence. RESULTS: All but one Long COVID respondent reported having PEM. There were many significant differences in the types of PEM triggers, symptoms experienced during PEM, and ways to recover and prevent PEM between Long COVID and ME/CFS. Similarities between Long COVID and ME/CFS included low and medium physical and cognitive exertion to trigger PEM, symptoms of fatigue, pain, immune reaction, neurologic, orthostatic intolerance, and gastrointestinal symptoms during PEM, rest to recover from PEM, and pacing to prevent PEM. CONCLUSION: People with Long COVID experience PEM. There were significant differences in PEM experienced by people with Long COVID compared to patients with ME/CFS. This may be due to the newness of Long COVID, not knowing what exertional intolerance is or how to manage it. [ABSTRACT FROM AUTHOR]

Immune-checkpoint inhibitors (ICIs) are the most effective treatments nowadays. Nivolumab was the second ICI used for treating solid tumors with amazing results. Patients treated with Nivolumab may react differently to this treatment. Some people tolerate this treatment very well without experiencing any adverse reactions, whilst some may have mild symptoms and a part of them can present severe reactions. In our research, we sought to identify the answers to four questions: 1. what type of cancer has more severe hypersensitivity reactions to Nivolumab, 2. what is the time frame for developing these severe reactions to Nivolumab, 3. whether it is best to continue or stop the treatment after a severe hypersensitivity reaction to Nivolumab and 4. what severe hypersensitivity reactions are the most frequent reported along Nivolumab treatment. This review also highlights another problem with regard to the usage of concomitant and prior medications or other methods of treatment (e.g., radiation therapy), which can also lead to severe reactions. Treatment with Nivolumab is very well tolerated, but patients should also be warned of the possibility of severe hypersensitivity reactions for which they should urgently see a doctor for a personalized evaluation. There are some options for individuals with severe hypersensitivity reactions, for eg. switching the medication or applying a desensitization protocol. [ABSTRACT FROM AUTHOR]

Celiac disease is a chronic autoimmune enteropathy affecting about 1% of the population. Gluten ingestion triggers an immune response in genetically susceptible patients, resulting in intestinal and extraintestinal disease manifestations. Current recommendations for diagnosis include serology for celiac-specific antibodies to transglutaminase, endomysium, and deamidated gliadin, and IgA serology. New highly accurate point-of-care tests can efficiently screen for celiac disease and improve the diagnostic timeframe. Definitive diagnosis is most commonly made via biopsy of the small bowel showing villous atrophy. A gluten-free diet with micronutrient supplementation is the only recommended treatment for celiac disease. Primary care providers must be able to recognize screening indications, refer patients appropriately, and provide proper patient education and follow-up. [ABSTRACT FROM AUTHOR]

Background: Nicotine replacement therapy (NRT) has proven effect in assisting smoking cessation. However, its effectiveness varies across studies and population groups. This may be due to differences in the rate of adherence. Hence, this review aims to examine the level of adherence to NRT and to assess if the level of adherence to NRT affects success of smoking cessation.Methods: A systematic review and meta-analysis was conducted using studies retrieved from five electronic databases (MEDLINE, Scopus, EMBASE, Web of science, and PsycINFO) and grey literature. Pooled analysis was conducted using Stata version 16 software. Methodological quality and risk of bias were assessed using the NIH Quality Assessment Tool. Analyses were done among those studies that used similar measurements to assess level of adherence and successful smoking cessation. Heterogeneity of studies was assessed using the Higgins' I2 statistical test. Funnel plots and Egger's regression asymmetry test were used to affirm presence of significant publication bias.Results: A total of 7521 adult participants of 18 years old and above from 16 studies were included in the analysis. Level of adherence to NRT among participants of randomised controlled trials were found to be 61% (95% CI, 54-68%), p-value of < 0.001 and I2 = 85.5%. Whereas 26% of participants were adherent among participants of population-based studies with 95% CI, 20-32%, p-value of < 0.001 and I2 = 94.5%. Level of adherence was the lowest among pregnant women (22%) with 95% CI, 18-25%, p-value of 0.31 and I2 = 15.8%. Being adherent to NRT doubles the rate of successful quitting (OR = 2.17, 95% CI, 1.34-3.51), p-value of < 0.001 and I2 = 77.6%.Conclusions: This review highlights a low level of adherence to NRT among participants of population-based studies and pregnant women as compared to clinical trials. Moreover, the review illustrated a strong association between adherence and successful smoking cessation. Hence, it is recommended to implement and assess large scale interventions to improve adherence. Health programs and policies are recommended to integrate the issue of adherence to NRT as a core component of smoking cessation interventions.Trial Registration: PROSPERO registration number: CRD42020176749 .

Background: Porphyromonas gingivalis is a major pathogen and has a high detection rate in periodontal disease. Fimbriae and hemagglutinin are expressed by P. gingivalis, and these play an important role in the adherence of the bacteria to periodontal tissue and biofilm formation. The aim of this study was to investigate the effects of sub-minimal inhibitory concentrations (sub-MICs) of azithromycin on the adherence of P. gingivalis, focusing on the inhibition of fimbriae expression and hemagglutinin activity.Methods: P. gingivalis ATCC 33277 were incubated anaerobically with sub-MICs of azithromycin at 37°C by gentle shaking for 18 hours. The bacterial cells were harvested, washed twice with phosphate-buffered saline (PBS), and the proteins analyzed by 12% sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and western blotting. Adherence assay and hemagglutinin activity tests were done with the same culture.Results: The results of SDS-PAGE indicated that the sub-MICs of azithromycin inhibited 41-kDa fimbrial protein expression and hemagglutinin activities. The disappearance of 41-kDa fimbrial protein expression and long fimbriae in 0.4 µg/mL, 0.2 µg/mL, and 0.1 µg/mL of azithromycin was confirmed by western blotting and transmission electron microscopy. The adherence of P. gingivalis to human gingival epithelial cells was reduced by sub-MICs of azithromycin compared with the adherence levels without antibiotic.Conclusions: These results suggest that sub-MICs of azithromycin may reduce the adherence of P. gingivalis to host cells, by inhibiting production of fimbriae and hemagglutinin activities. Therefore, azithromycin can be used as a biofilm treatment of periodontal disease caused by P. gingivalis. [ABSTRACT FROM AUTHOR]

Adherence to allergen immunotherapy (AIT) is crucial for its efficacy. Subcutaneous AIT requires monthly visits (or more extended in the case of venom immunotherapy), while sublingual AIT is performed with a daily intake of allergen drops. Non-adherence to an AIT schedule and premature discontinuation are common problems. Various studies have shown controversial results on the rate of AIT adherence. The aim of this review is to describe the problem of non-adherence and to offer some evidence-based advice to allergologists on how to increase it. Better patient education at the beginning of treatment, sharing with patients the decision on which type of immunotherapy to select and showing sincere interest in their treatment concerns are some tips that can help to increase adherence. A well organized allergologist time schedule not only increases safety but also offers the possibility of close follow-up and an increase in patient loyalty. [ABSTRACT FROM AUTHOR]

Objectives: There is a dearth of literature on effects of nonadherence to hepatitis C virus (HCV) direct-acting antiviral (DAA) regimens; thus, the objective of our study was to assess the impact of adherence on sustained virologic response (SVR) and evaluate factors associated with nonadherence, such as race, psychiatric comorbidities, and therapy length.Methods: We conducted a retrospective cohort study of patients completing DAA treatment between January 2014 and May 2016 within an interdisciplinary hepatology clinic. Adherence was defined a priori as 95% or greater of DAA doses taken within the prescribed treatment period. Post hoc analyses were done with adherence thresholds ≥ 90%, ≥ 85%, and ≥ 80% and adherence as a continuous percentage. Patients lost to follow-up before completing therapy or that discontinued therapy early were excluded from analyses. The association between adherence and SVR rates was assessed using Fisher exact test (for adherence thresholds) and the Wilcoxon rank-sum test (for continuous adherence). Factors associated with adherence were assessed similarly using Fisher exact and Wilcoxon rank-sum tests and multivariable logistic regression.Results: Overall adherence was high, with an average of 97.8% of DAA doses taken within the prescribed treatment period. Achievement of SVR was not significantly different in adherent and nonadherent patients, at an adherence threshold of 95% or greater (93.4% vs. 88.5%; P = 0.246) or any of the post hoc adherence thresholds (≥ 90% [93.3% vs. 84.0%; P = 0.098], ≥ 85% [92.8% vs. 91.7%; P = 0.601], ≥ 80% [92.9% vs. 80.0%; P = 0.315], or as a continuous percentage [P = 0.328]). Black patients were significantly more likely to be nonadherent to DAAs than non-black patients at each adherence threshold (P < 0.05). No other factors evaluated were associated with nonadherence.Conclusion: A numerically higher but not statistically significant SVR failure rate was noted in nonadherent patients, although the gold standard definition for adherence remains to be established. Black patients may require additional adherence support. [ABSTRACT FROM AUTHOR]

The article highlights several pharmacological methods of adherence assessment in HIV Prevention. topics including use of Tenofovir (TFV) disoproxil fumarate (TDF) with emtricitabine (FTC) an oral fixed dose combination tablet for HIV pre-exposure prophylaxis (PrEP); recent dosing markers like plasma testing, Urine analysis, and FTC concentrations in saliva; and cumulative dosing markers like TFV-diphosphate in peripheral blood mononuclear cell and dried blood spots and hair growth matrix.

Background: To investigate the associations between the perceived barriers and benefits of using HIV pre-exposure prophylaxis medication, including worries about the side effects, disliking taking drugs, perceived burden of taking medication, positive expectations as to the efficacy of the drugs, favourable doctor-patient relationships, and medication adherence among men who have sex with men (MSM) to provide a target for improving medication adherence and reducing HIV infection among MSM.Methods: MSM were recruited in western China from April 2013 to October 2014, administered oral tenofovir (TDF) daily and followed up every 12 weeks for 2 years. At each follow-up, the medication rate was calculated based on the self-reported number of missed doses over 2 weeks, and then, the medication adherence was evaluated. The barriers and benefits perceived during medication were obtained by a self-administered questionnaire, and their effects on medication adherence were analysed by linear mixed models.Results: A total of 411 participants were enrolled in this study, and 1561 follow-up observation points were obtained. The average medication rate was 0.62 ± 0.37, and the medication rate increased with longer follow-up (P < 0.05). The medication rate was higher among MSM who were divorced (compared to those who were unmarried, P < 0.0001). MSM with more positive expectations as to the efficacy of the drugs showed higher rates of medication (P < 0.0001), while those who were more worried about side effects had a lower medication rate (P = 0.0208). In contrast, the dislike of taking the drugs and the burden perceived during medication had no effects on the actual medication rate of taking TDF (P > 0.05).Conclusion: How to obtain and maintain high medication adherence among MSM is the key to the PrEP intervention strategy for effective reduction of HIV infection. For MSM in China, we should deepen their understanding of the effectiveness and safety of PrEP and increase their confidence in PrEP, thereby improving their medication adherence.Trial Registration: ChiCTR-TRC-13003849 .

Millions of Americans are living with at least one chronic disease, and while the majority has been prescribed medication to control symptoms-medication adherence is a widespread problem. Medication nonadherence varies by chronic disease, patient characteristics, and insurance coverage, and previous research has identified non-financial barriers including disease-related knowledge, health literacy and polypharmacy. However, given the increasing popularity of online health communities, little research examines the influence of user-generated content on health behaviors. Many patients use the internet to seek and share information related to prescription medications. The current study examines patients' attitudes and behavioral intentions formed (in part) by the user-generated content exchanged within online health communities. Specifically, the Health Belief Model's perceived barriers and perceived benefits are explored here. Twenty members from online health communities related to arthritis are interviewed to understand how peer-to-peer communication is used in regards to medication adherence. Three themes emerged from the data, including striving for pain relief, negotiating potential side effects, and finding the new normal. Theoretical and practical implications are discussed.

Background Co-administration of vaccines in adolescents may improve coverage. We assessed co-administration of quadrivalent meningococcal serogroups A, C, W and Y tetanus toxoid-conjugate vaccine (MenACWY-TT), human papillomavirus 16/18 AS04-adjuvanted vaccine (AS04-HPV16/18) and tetanus-diphtheria-acellular pertussis vaccine (Tdap) in girls and young women. Methods In this phase IIIb study (NCT01755689), 1300 healthy 9–25-year-old females were randomized (1:1:1:1:1) to receive: MenACWY-TT at month (M) 0 and AS04-HPV16/18 at M1, M2, M7; MenACWY-TT and AS04-HPV16/18 at M0 and AS04-HPV16/18 at M1, M6; AS04-HPV16/18 at M0, M1, M6; MenACWY-TT, Tdap and AS04-HPV16/18 at M0 and AS04-HPV16/18 at M1, M6; Tdap and AS04-HPV16/18 at M0 and AS04-HPV16/18 at M1, M6. Immunogenicity, safety and reactogenicity were evaluated. Results Immunogenicity of MenACWY-TT and AS04-HPV16/18 when co-administered was non-inferior to that of the 2 vaccines given separately. Co-administration of MenACWY-TT, AS04-HPV16/18 and Tdap was non-inferior to MenACWY-TT administered alone or to Tdap co-administered with AS04-HPV16/18 in terms of immunogenicity for all vaccine components, except pertussis antigens. Post-vaccination, ≥89.5% of participants reached antibody levels above the pre-specified threshold for all antigens. No safety concerns were identified. Conclusion Our data support co-administration of MenACWY-TT with Tdap and AS04-HPV16/18 vaccines in adolescents. [ABSTRACT FROM AUTHOR]

Rapid elimination of microbes from the bloodstream, along with the ability to mount an adaptive immune response, are essential for optimal host-defense. Kupffer cells are strategically positioned in the liver sinusoids and efficiently capture circulating microbes from the hepatic artery and portal vein, thus preventing bacterial dissemination. In vivo and in vitro studies have probed how complement receptor of the immuno g lobulin superfamily (CRIg), also referred to as Z39Ig and V-set and Ig domain-containing 4 (VSIG4), acts as a critical player in pathogen recognition and clearance. While recent data suggested that CRIg may bind bacterial cell wall components directly, the single transmembrane receptor is best known for its interaction with complement C3 opsonization products on the microbial surface. On Kupffer cells, CRIg must capture opsonized microbes against the shear forces of the blood flow. In vivo work reveals how immune adherence (IA), a process in which blood platelets or erythrocytes associate with circulating bacteria, plays a critical role in regulating pathogen capture by CRIg under flow conditions. In addition to its typical innate immune functions, CRIg was shown to directly and indirectly influence adaptive immune responses. Here, we review our current understanding of the diverse roles of CRIg in pathogen elimination, anti-microbial immunity and autoimmunity. In particular, we will explore how, through selective capturing by CRIg, an important balance is achieved between the immunological and clearance functions of liver and spleen.

Background: Inadequate description of non-pharmacological complex interventions in trial publications means that they cannot be replicated or assessed for generalisability. There are published guidelines on how to describe an intervention, such as those from the CONSORT Group. However, there have been few evaluations of whether intervention reporting is improving.Methods: We aimed to assess whether descriptions of multicomponent, non-pharmacological interventions evaluated in randomised trials are improving. To do so, we chose trials of educational and psychotherapeutic interventions to promote adherence to therapy, and compared those published between 2002 and 2007 (Time-1) with those between 2010 and 2015 (Time-2). These time periods were chosen to concord with the publication in 2008 of the CONSORT extension statement of reporting guidelines for non-pharmacological treatment which included items on intervention description. We assessed 19 items, based on the CONSORT Statement and the more recent Template for Intervention Description and Replication Checklist (TIDieR). Two reviewers independently extracted data. We created a quality score of the eight items we considered key information for replication and assessment of generalisability (setting, provider, recipient, comparator, intervention intensity, how it was conducted, existence of a manual or protocol, and detail of whether there was an assessment of fidelity). Score per item was '1' if reported adequately and '0' if not.Results: Of the eligible trials, 42 were published in Time-1 and 134 published in Time-2. The trials included were published in 112 peer-reviewed journals, 52 of these journals currently require authors to follow the CONSORT Statements, while only one recommended adherence to the TIDieR. Most items of CONSORT and TIDieR were reported by more than half of the trials at both time points. Few trials reported fidelity. A large proportion of the trials did not report the existence of a manual or protocol, or what the comparator group received. We found no statistically significant improvement in the eight-item quality score (Time-1: mean 5.71 (standard deviation (SD) 1.09), Time-2: 5.87 (SD 1.28), p = 0.49).Conclusions: We found no overall evidence that reporting the specifics of multicomponent, non-pharmacological interventions is improving. Details to replicate interventions remain lacking, impairing best implementation or meaningful further research. Editorial endorsement of reporting checklists needs to be more extensive.

The aim of the study was to determine the prevalence of virulence genes responsible for the adhesion ( flaA , cadF and racR ) and invasion ( virB11 , iam and pldA ) in Campylobacter isolates from cattle and swine and determine their adherence and invasion abilities. The studies conducted revealed high prevalence rate of adherence and invasion associated genes irrespective of the isolates origin. All Campylobacter strains of swine and cattle origin adhered to HeLa cells at mean level 0.1099% ± SD 0.1341% and 0.0845% ± SD 0.1304% of starting viable inoculum, respectively. However swine isolates exhibited higher invasion abilities (0.0012% ± SD 0.0011%) compared to bovine isolates (0.00038% ± SD 0.00055%). The results obtained revealed significantly positive correlation between invasion and adherence abilities of swine origin isolates (R = 0.4867 in regard to C. jejuni and R = 0.4507 in regard to C. coli ) and bovine origin isolates (R = 0.726 in regard to C. jejuni ). Bacterial virulence is multifactorial and it is affected by the expression of virulence genes. Moreover the presence of virulence genes determines the ability of Campylobacter isolates to adhere and invade the cells. [ABSTRACT FROM AUTHOR]

Objective: Non-adherence to tamoxifen is common in breast cancer survivors and is associated with poor clinical outcomes. This study aimed to understand womens' experiences of taking tamoxifen and to identify factors which may be associated with non-adherence.Design: A qualitative study using semi-structured interviews.Methods: Thirty-two breast cancer survivors who had been prescribed tamoxifen took part in interviews conducted face to face or over the telephone. They were transcribed verbatim and analysed using inductive thematic analysis with elements of grounded theory.Results: A key theme identified in the data was weighing up costs and benefits of treatment, which resulted in women falling into three groups; tamoxifen is keeping me alive, tamoxifen is not worth the reduced risk of recurrence, or conflicting beliefs about the harms and benefits of treatment. Additional themes were living with risk of recurrence and information & support.Conclusions: Women who believed that the necessity of tamoxifen outweighed its costs were more likely to be adherent, whereas women who thought that the benefits did not outweigh the side effects were more likely to have discontinued. A third more ambivalent group believed strongly in the importance of treatment, but were struggling with side effects and were often non-adherent. Patients sometimes felt unsupported and discussed a need for more comprehensive information. To increase adherence, future research needs to explore ways to increase beliefs around tamoxifen necessity and how to help women cope with side effects. Statement of contribution What is already known on this subject? Non-adherence to tamoxifen is associated with increased risk of recurrence and mortality. Up to 50% of patients are non-adherent to tamoxifen by the fifth year of treatment Few consistent predictors of tamoxifen non-adherence have been identified. What does this study add? Many women report not knowing how to manage their side effects. Non-adherence is related to how women weigh up their side effects against their medication beliefs. Interventions aiming to increase necessity beliefs and improve symptom management may be effective. [ABSTRACT FROM AUTHOR]

Background Participants' experience with a screening test can influence adherence, and therefore the efficacy of screening programs. We compared screening with unsedated flexible sigmoidoscopy and fecal immunochemical testing (FIT) for participants' satisfaction with the decision and for willingness to repeat colorectal cancer screening. Methods In a prospective, randomized trial 3257 individuals (50 - 74 years) were invited to either flexible sigmoidoscopy or FIT (1:1), of whom 1650 took up the offer (52.6 %). In total, 1497 screening participants completed at least one questionnaire, either before screening, and/or at three time points in the following year, that measured willingness to repeat screening, willingness to recommend screening, and satisfaction with decision to attend. There were 769 and 728 responders in the flexible sigmoidoscopy and FIT group, respectively. Additionally, 581 flexible sigmoidoscopy participants also completed a pain questionnaire. Results 1 year later, 10 % of the flexible sigmoidoscopy participants were not willing to repeat screening, compared to 5 % of FIT participants. A higher percentage of women compared to men would not repeat flexible sigmoidoscopy screening (adjusted odds ratio [OR] 2.52, 95 % confidence interval [95 %CI] 1.48 to 4.28). Notably, 22 % of women reported pain during flexible sigmoidoscopy compared to 5 % of men. When we added pain to the statistical model, pain was significantly associated with unwillingness to repeat flexible sigmoidoscopy (OR 3.15, 95 %CI 1.68 to 5.87), while gender was no longer associated (OR 1.53, 95 %CI 0.82 to 2.88). Conclusion Acceptability for flexible sigmoidoscopy and for FIT was high among Norwegian screening participants, though FIT participants were more willing to repeat screening. Women were less willing to repeat screening with flexible sigmoidoscopy compared to men. This gender difference seemed partly due to pain, and therefore preventable.This study is registered at ClinicalTrials.gov: NCT01538550. [ABSTRACT FROM AUTHOR]

Background: Guidelines for the treatment of nonmetastatic inflammatory breast cancer (IBC) using trimodality therapy (TT) (chemotherapy, surgery, and radiotherapy) have remained largely unchanged since 2000. However, many patients with nonmetastatic IBC do not receive TT. It is unknown how patient-level (PL) and facility-level (FL) factors contribute to TT use.Methods: Using the National Cancer Data Base, patients with nonmetastatic IBC who underwent locoregional treatment from 2003 through 2011 were identified. The authors correlated PL factors, including demographic and tumor characteristics, with TT use. An observed-to-expected ratio for the number of patients treated with TT was calculated for each hospital by adjusting for significant PL factors. Hierarchical mixed effects models were used to assess the percentage of variation in TT use attributable to PL and FL factors, respectively.Results: Of the 542 hospitals examined, 55 (10.1%) and 24 (4.4%), respectively, were identified as significantly low and high outliers for TT use (P<.05). The percentage of the total variance in the use of TT attributable to the facility (11%) was nearly triple the variance attributable to the measured PL factors (3.4%). The nomogram generated from multivariate logistic regression of PL factors only allows a facility to assess TT use given their PL data.Conclusions: FL factors rather than PL factors appear to contribute disproportionately to the underuse of TT in patients with nonmetastatic IBC. To improve treatment guideline adherence for patients with nonmetastatic IBC, it is critical to identify the specific FL factors associated with TT underuse. More organized FL intervention is required to train physicians and to build multidisciplinary teams. Cancer 2017;123:2618-25. © 2017 American Cancer Society. [ABSTRACT FROM AUTHOR]

Introduction: Successful population-level antiretroviral therapy (ART) adherence will be necessary to realize both the clinical and prevention benefits of antiretroviral scale-up and, ultimately, the end of AIDS. Although many people living with HIV are adhering well, others struggle and most are likely to experience challenges in adherence that may threaten virologic suppression at some point during lifelong therapy. Despite the importance of ART adherence, supportive interventions have generally not been implemented at scale. The objective of this review is to summarize the recommendations of clinical, research, and public health experts for scalable ART adherence interventions in resource-limited settings. Methods: In July 2015, the Bill and Melinda Gates Foundation convened a meeting to discuss the most promising ART adherence interventions for use at scale in resource-limited settings. This article summarizes that discussion with recent updates. It is not a systematic review, but rather provides practical considerations for programme implementation based on evidence from individual studies, systematic reviews, meta-analyses, and the World Health Organization Consolidated Guidelines for HIV, which include evidence from randomized controlled trials in low- and middle-income countries. Interventions are categorized broadly as education and counselling; information and communication technology-enhanced solutions; healthcare delivery restructuring; and economic incentives and social protection interventions. Each category is discussed, including descriptions of interventions, current evidence for effectiveness, and what appears promising for the near future. Approaches to intervention implementation and impact assessment are then described. Results and discussion: The evidence base is promising for currently available, effective, and scalable ART adherence interventions for resource-limited settings. Numerous interventions build on existing health care infrastructure and leverage available resources. Those most widely studied and implemented to date involve peer counselling, adherence clubs, and short message service (SMS). Many additional interventions could have an important impact on ART adherence with further development, including standardized counselling through multi-media technology, electronic dose monitoring, decentralized and differentiated models of care, and livelihood interventions. Optimal targeting and tailoring of interventions will require improved adherence measurement. Conclusions: The opportunity exists today to address and resolve many of the challenges to effective ART adherence, so that they do not limit the potential of ART to help bring about the end of AIDS.

Objective: This study examined statin adherence amongst Kuwaiti hypercholesterolemic patients in order to identify factors associated with poor adherence and to determine whether or not an association exists between statin adherence and the risk profile of coronary heart disease (CHD).Subjects and Methods: Two hundred hypercholesterolemic patients (30-69 years of age) were recruited from Kuwaiti primary healthcare clinics and interviewed about demographic characteristics, pre-existing self-reported medical conditions and prescribed medications. The Morisky Medication Adherence Scale was used to assess statin adherence (a self-reported, medication-adherence questionnaire divided into 3 levels, with a score of 8 denoting high adherence, 6 to <8 denoting medium adherence and <6 denoting low adherence). Data regarding anthropometric, psychological and serum risk factors were collected using 2 additional questionnaires, laboratory tests and bioelectrical impedance scales. Binary logistic regression was used to determine predictors of adherence and general linear modelling was used to test relationships between continuous outcomes and statin adherence.Results: Of the 200 participants, 117 (58.5%) reported low adherence, 83 (41.5%) reported medium adherence and no patients (0%) scored high adherence. Younger patients (aged 30-50 years) had lower adherence than older patients (>50 years) [odds ratio (OR) 1.05; 95% confidence interval (CI) 1.01-1.09] for every extra year; p < 0.01). Those without diabetes, i.e. 113 (56.5%), were less likely to report medium adherence than those with diabetes (OR 0.42; 95% CI 0.23-0.75; p < 0.01). Low statin adherence was associated with higher levels of plasma cholesterol (p < 0.001) and low-density lipoprotein (p < 0.01).Conclusion: In this study, there was a high prevalence of low statin adherence, especially among younger patients with fewer concomitant diseases. The results indicated an inverse relationship between statin adherence and CHD risk profile. [ABSTRACT FROM AUTHOR]

Objective: To examine medication adherence and associated factors among adolescents with bipolar disorder (BP) using both objective and subjective methods.Method: Participants were 21 adolescents with a primary BP diagnosis recruited from a pediatric specialty clinic. All participants were prescribed at least one psychotropic medication. Self- and parent-reported adherence were assessed monthly over 6 months. Objective data on medication adherence were gathered through an electronic weekly pillbox. Demographic and clinical factors were assessed through self, parent, and physician ratings at baseline, 3, and 6 months.Results: Objective data indicate 41.5% of doses (58.6% of days) were not taken as prescribed over a mean of 3 months of follow-up. Subjective reports (patient, parent, and physician) significantly overestimated adherence as compared with objective data. Factors from multiple domains were associated with poorer adherence, including more daily doses, higher weight, dose timing (poorer on mornings/afternoons and weekends), less temporal proximity to medication management appointment, greater self-reported cognitive difficulties with adhering to treatment; the most potent predictor of missed doses was greater overall illness severity.Conclusions: Findings provide further evidence of poor medication adherence among youth with BP, and highlight the limits of subjective report of adherence. Providers should give careful attention to adherence when making decisions regarding treatment response and changes to medication regimen when working with youth with BP. [ABSTRACT FROM AUTHOR]

The activation of the complement system by canonical and non-canonical mechanisms results in the generation of multiple C3 and C5 cleavage fragments including anaphylatoxins C3a and C5a as well as opsonizing C3b/iC3b. It is now well appreciated that anaphylatoxins not only act as pro-inflammatory mediators but as immunoregulatory molecules that control the activation status of cells and tissue at several levels. Likewise, C3b/iC3b is more than the opsonizing fragment that facilitates engulfment and destruction of targets by phagocytes. In the circulation, it also facilitates the transport and delivery of bacteria and immune complexes to phagocytes, through a process known as immune adherence, with consequences for adaptive immunity. Here, we will discuss non-classical immunoregulatory properties of C3 and C5 cleavage fragments. We highlight the influence of anaphylatoxins on Th2 and Th17 cell development during allergic asthma with a particular emphasis on their role in the modulation of CD11b+ conventional dendritic cells and monocyte-derived dendritic cells. Furthermore, we discuss the control of anaphylatoxin-mediated activation of dendritic cells and allergic effector cells by adaptive immune mechanisms that involve allergen-specific IgG1 antibodies and plasma or regulatory T cell-derived IL-10 production. Finally, we take a fresh look at immune adherence with a particular focus on the development of antibacterial cytotoxic T-cell responses. [ABSTRACT FROM AUTHOR]

The purpose of this work was to verify in vitro adherence of E. corrodens and S. oralis to the surface of tongue piercings made of surgical steel, titanium, Bioplast, and Teflon. For this, 160 piercings were used for the count of Colony Forming Units (CFU) and 32 piercings for analysis under scanning electron microscopy. Of these, 96 (24 of each type) were individually incubated in 5 mL of BHI broth and 50 μL of inoculum at 37°C/24 h. The other 96 piercings formed the control group and were individually incubated in 5 mL of BHI broth at 37°C/24 h. Plates were incubated at 37°C/48 h for counting of CFU/mL and data were submitted to statistical analysis (p value <0.05). For E. corrodens, difference among types of material was observed (p<0.001) and titanium and surgical steel showed lower bacterial adherence. The adherence of S. oralis differed among piercings, showing lower colonization (p<0.007) in titanium and surgical steel piercings. The four types of piercings were susceptible to colonization by E. corrodens and S. oralis, and bacterial adhesion was more significant in those made of Bioplast and Teflon. The piercings presented bacterial colonies on their surface, being higher in plastic piercings probably due to their uneven and rough surface. [ABSTRACT FROM AUTHOR]

The article presents a study which focuses on the role of the respiratory epithelium in defending against microbial pathogens and in facilitating synergistic pathogenic interactions. The topics discussed include role of the respiratory epithelium in innate and adaptive immunity, the mechanism that drives the increase of bacterial adherence and colonization of viral infection and the skew of direction of immune status of the respiratory tract to predispose to secondary bacterial infection.

In atopic dermatitis (AD), the skin inflammation is believed to occur due to a misdirected immune reaction against harmless antigens on the one hand, and to a disturbed skin barrier on the other. In recent years, vast efforts have been made to investigate the relevance and details of the immune response to allergens. Clinically, it was demonstrated for the first time that aeroallergen exposure leads to worsening of AD symptoms. An overexpression of Th2 cytokines has been observed in acute and subacute lesions of AD. The clinical impact of the key Th2 cytokines IL-4 and IL-13 on atopic dermatitis has recently been shown in clinical studies with dupilumab, a monoclonal antibody which blocks the IL-4/IL-13 receptor.In vitrodata indicate, however, that the T cell response is not solely Th2-polarized but may lead to heterogeneous cytokine production involving IFN-γ and IL-17 in an allergen-dependent manner. Classical thymus-derived Foxp3 T cells have interestingly been detected in elevated numbers in the circulation of AD patients. Therapeutic approaches with allergen specific immunotherapy aim to induce regulatory T cells of the Tr1 type. The strikingly altered microbiome of AD skin with diminished diversity of bacteria on lesional skin but increases ofS. aureuscolonization and the sensitization against microbial allergens and homologue self-proteins deserve special attention. For the treatment of itch symptoms, which still represent a challenge in daily practice, promising data have been published on the relevance of the H(histamine)4-receptor and on mediators such as IL-31, TSLP.

Background: There is evidence for a relevant role of inflammation in the pathogenesis of Parkinson's disease (PD). Mutations in the LRRK2 gene represent the most frequent genetic cause for autosomal dominant PD. LRRK2 is highly expressed in macrophages and microglia suggesting an involvement in inflammatory pathways. The objectives are to test (1) whether idiopathic PD and LRRK2-associated PD share common inflammatory pathways or present distinct profiles and (2) whether non-manifesting LRRK2 mutation carriers present with similar aspects of inflammatory profiles as seen in PD-affected patients.Methods: We assessed serum profiles of 23 immune-associated markers and the brain-derived neurotrophic factor in 534 individuals from the MJFF LRRK2 consortium.Results: A large proportion of inflammatory markers were gender-dependent. Both PD-affected cohorts showed increased levels of the pro-inflammatory marker fatty-acid-binding protein. Additionally, idiopathic PD but not LRRK2-associated PD patients showed increased levels of the pro-inflammatory marker interleukin-12-p40 as well as the anti-inflammatory species interleukin-10, brain-derived neurotrophic factor, and stem cell factor. Non-manifesting LRRK2 mutation carriers including those with prodromal characteristics of PD presented with control-like inflammatory profiles.Conclusions: Concomitant inflammation seems to be associated with idiopathic and LRRK2-associated PD. Identifying PD patients in whom inflammatory processes play a major role in their pathophysiology might offer a new therapeutic window at least for a subgroup of patients. Since non-manifesting LRRK2 mutation carriers with symptoms of the prodromal phase of PD did not show inflammatory profiles, activation of the immune system seems not an early event in the disease cascade.

Objectives: The purpose of this study was to evaluate the impact of antidiabetic medication adherence on hospital utilization in patients with newly diagnosed type 2 diabetes mellitus (T2D). This study specifically analyzed patients with newly diagnosed T2D with the intent of lessening intragroup disease severity differences, and adjusting for a range of other clinical and demographic characteristics.Methods: This retrospective US claims database study evaluated adults with newly diagnosed T2D who started antidiabetic medications in 2005-2009, had ≥ 2 antidiabetic medication claims after their first (baseline). Medication adherence was evaluated using the medication possession ratio (MPR) of any or all antidiabetic medication(s) during the 3-year post-baseline period. Repeated-measures analyses examined changes in inpatient utilization from the pre- to post-baseline period. The impact of adherence on hospital utilization during the post-baseline period was evaluated with a logistic regression model to adjust for confounding factors.Results: The study included 192,717 patients (mean age, 55.0 years). Mean MPR for antidiabetic therapy was 0.74. MPR was highest in elderly patients and Medicare beneficiaries. Mean annualized inpatient admissions during the 3-year post-baseline period were significantly lower in patients with MPR ≥ 0.80 (1.4) than in those with MPR < 0.80 (2.2; P < 0.05). Logistic regression analysis, adjusting for patient characteristics and prior inpatient utilization, showed 39% lower odds of hospitalization (OR = 0.61; 95% CI = 0.534-0.693) for patients with MPR ≥ 0.80. People with T2D-related complications or hospitalization had approximately 2- to 3-fold higher risk of subsequent hospitalization.Conclusions: In newly diagnosed T2D patients with antidiabetic therapy in the first three ensuing years, higher antidiabetic medication adherence was significantly associated with lower hospital inpatient utilization before and after adjusting for patient characteristics.

Background and aims:Treatment adherence is one of the most important factors that may determine treatment response in patients with bipolar disorders (BD). Many factors have been described to be associated with treatment adherence in BD. Temperament that can influence the course of BD will have an impact on treatment adherence. The aim of this study is to investigate temperament effect on treatment adherence in euthymic patients with BD-I.Methods:Eighty patients with BD-I participated in the study. A psychiatrist used the Structured Clinical Interview for DSM-IV Axis-I Disorders to determine the diagnosis and co-morbidities. Hamilton Depression and Young Mania Rating Scale were used to detect the remission. We used the Temperament Evaluation of Memphis, Pisa, Paris, San Diego Autoquestionnaire and the 4-item Morisky Medication Adherence Scale to evaluate temperament and treatment adherence, respectively. The study group was divided into two groups as “treatment adherent” and “treatment non-adherent”.Results:The cyclothymic and anxious temperament scores of the treatment non-adherent patients with BD-I were significantly higher than those of the treatment adherent group (p < 0.001, p = 0.006, respectively). Multiple linear regression analysis determined that cyclothymic temperament predicted treatment non-adherence (p = 0.009).Conclusion:It should be kept in mind that BD-I patients with cyclothymic temperament may be treatment non-adherent and future studies should explore whether temperament characteristics deteriorate BD-I course by disrupting treatment adherence.

Neutralizing antibodies induced by vaccination or natural infection play a critically important role in protection against the viral diseases. In general, neutralization of the viral infection occurs via two major pathways: pre- and post-attachment modes, the first being the most important for such infections as influenza and polio, the latter being significant for filoviruses. Neutralizing capacity of antibodies is typically evaluated by virus neutralization assays that assess reduction of viral infectivity to the target cells in the presence of functional antibodies. Plaque reduction neutralization test, microneutralization and immunofluorescent assays are often used as gold standard virus neutralization assays. However, these methods are associated with several important prerequisites such as use of live virus requiring safety precautions, tedious evaluation procedure and long assessment time. Hence, there is a need for a robust, inexpensive high throughput functional assay that can be performed rapidly using inactivated virus, without extensive safety precautions. Herein, we report a novel high throughput Fluorescence Adherence Inhibition assay (fADI) using inactivated virus labeled with fluorescent secondary antibodies virus and Vero cells or erythrocytes as targets. It requires only few hours to assess pre-attachment neutralizing capacity of donor sera. fADI assay was tested successfully on donors immunized with polio, yellow fever and influenza vaccines. To further simplify and improve the throughput of the assay, we have developed a mathematical approach for calculating the 50% titers from a single sample dilution, without the need to analyze multi-point titration curves. Assessment of pre- and post-vaccination human sera from subjects immunized with IPOL®, YF-VAX® and 2013–2014 Fluzone® vaccines demonstrated high efficiency of the assay. The results correlated very well with microneutralization assay performed independently by the FDA Center of Biologics Evaluation and Research, with plaque reduction neutralization test performed by Focus Diagnostics, and with hemaglutination inhibition assay performed in-house at Sanofi Pasteur. Taken together, fADI assay appears to be a useful high throughput functional immunoassay for assessment of antibody-related neutralization of the viral infections for which pre-attachment neutralization pathway is predominant, such as polio, influenza, yellow fever and dengue.

Background: In Africa, fewer than half of patients receiving therapy for multidrug-resistant TB (MDR TB) are successfully treated, with poor outcomes reported for HIV-coinfected patients.Methods: A standardised second-line drug (SLD) regimen was used in a non-governmental organisation-Ministry of Health (NGO-MOH) collaborative community and hospital-based programme in Ethiopia that included intensive side effect monitoring, adherence strategies and nutritional supplementation. Clinical outcomes for patients with at least 24 months of follow-up were reviewed and predictors of treatment failure or death were evaluated by Cox proportional hazards models.Results: From February 2009 to December 2014, 1044 patients were initiated on SLD. 612 patients with confirmed or presumed MDR TB had ≥ 24 months of follow-up, 551 (90.0%) were confirmed and 61 (10.0%) were suspected MDR TB cases. 603 (98.5%) had prior TB treatment, 133 (21.7%) were HIV coinfected and median body mass index (BMI) was 16.6. Composite treatment success was 78.6% with 396 (64.7%) cured, 85 (13.9%) who completed treatment, 10 (1.6%) who failed, 85 (13.9%) who died and 36 (5.9%) who were lost to follow-up. HIV coinfection (adjusted HR (AHR): 2.60, p<0.001), BMI (AHR 0.88/kg/m(2), p=0.006) and cor pulmonale (AHR 3.61, p=0.003) and confirmed MDR TB (AHR 0.50, p=0.026) were predictive of treatment failure or death.Conclusions: We report from Ethiopia the highest MDR TB treatment success outcomes so far achieved in Africa, in a setting with severe resource constraints and patients with advanced disease. Intensive treatment of adverse effects, nutritional supplementation, adherence interventions and NGO-MOH collaboration were key strategies contributing to success. We argue these approaches should be routinely incorporated into programmes. [ABSTRACT FROM AUTHOR]

Objective. To find a convenient and efficient way to isolate MSCs from human menstrual blood and to investigate their biological characteristics, proliferative capacity, and secretion levels. Methods. MSCs were isolated from menstrual blood of 3 healthy women using adherence. Cell immunological phenotype was examined by flow cytometry; the adipogenic, osteogenic, and chondrogenic differentiation of MSCs was examined by Oil-Red-O staining, ALP staining, and Alcian Blue staining, respectively; and the secretion of cytokines, including vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF), and insulin-like growth factor-1 (IGF-1), was detected using enzyme-linked immunosorbent assay. Results. MB-MSCs were successfully isolated from human menstrual blood using adherence. They were positive for CD73, CD105, CD29, and CD44, but negative for CD31 and CD45. The differentiated MB-MSCs were positive for ALP staining, Oil-Red-O staining, and Alcian Blue staining. In addition, they could secrete antiapoptotic cytokines, such as VEGF, IGF-1, and HGF. Conclusion. It is feasible to isolate MSCs from human menstrual blood, thus avoiding invasive procedures and ethical controversies. Adherence could be a promising alternative to the density gradient centrifugation for the isolation of MSCs from menstrual blood. [ABSTRACT FROM AUTHOR]

The neonatal FcR (FcRn) belongs to the extensive and functionally divergent family of MHC molecules. Contrary to classical MF1C family members, FcRn possesses little diversity and is unable to present Ags. Instead, through its capacity to bind IgG and albumin with high affinity at low pfl, it regulates the serum half-lives of both of these proteins. In addition, FcRn plays an important role in immunity at mucosal and systemic sites through its ability to affect the lifespan of IgG, as well as its participation in innate and adaptive immune responses. Although the details of its biology are still emerging, the ability of FcRn to rescue albumin and IgG from early degradation represents an attractive approach to alter the plasma half-life of pharmaceuticals. We review some of the most novel aspects of FcRn biology, immune as well as nonimmune, and provide some examples of FcRn-based therapies. [ABSTRACT FROM AUTHOR]

Background The use of potent immunosuppressive drugs and increased travel by renal transplant recipients ( RTR) has augmented the risk for infectious complications. Immunizations and changes in lifestyle are protective. The Kidney Disease: Improving Global Outcomes ( KDIGO) Transplant Work Group has developed guidelines on vaccination following solid organ transplantation. The degree of adherence to these guidelines is unknown, as is which barriers must be overcome to improve adherence. Methods We performed a cross-sectional national survey among Dutch nephrologists to assess vaccination policy and adherence to the KDIGO guidelines. In addition, to investigate awareness and attitude of RTR regarding their risk of infection, we performed a cross-sectional survey of RTR in our outpatient clinic. Results A total of 132 (63%) nephrologists completed the survey. Reported immunization rates were 90.8% for influenza and 27.3% for hepatitis B. However, pneumococcal, tetanus toxoid, and meningococcal immunization rates were low. Twenty-seven percent of respondents were familiar with the guideline contents. The most frequent perceived barrier to guideline adherence was expectation of low effectiveness. A total of 403 RTR (62%) completed the survey. Sixty-eight percent perceived more risk for complicated infection. A significant correlation was found between education level and variables concerning awareness and attitude toward risk of infection. Conclusions Our results show that nephrologists' knowledge of and adherence to the recommendations regarding immunization after renal transplantation is suboptimal. Most Dutch RTR are aware of their increased risk and the possible seriousness of infectious complications. However, their behavior does not match their awareness. This disparity points to an important role for nephrologists in providing adequate counseling. [ABSTRACT FROM AUTHOR]

BACKGROUND: Medication non-adherence is a major impediment to the management of cardiovascular disease risk factors. A better understanding of the modifying factors underlying medication non-adherence among individuals with known cardiovascular disease may inform approaches for addressing non-adherence. OBJECTIVE: The purpose of this study was to identify demographic and patient characteristics, medical comorbidities, psychosocial factors, and health belief-related factors associated with medication non-adherence among patients with known cardiovascular disease. DESIGN: We performed secondary analysis of baseline data from a randomized trial. PATIENTS: The study included 405 patients with a diagnosis of hypertension and history of acute myocardial infarction that was diagnosed within a three-year period prior to enrollment. MAIN MEASURES: Baseline demographics and patient characteristics, medical comorbidities, psychosocial factors, health belief-related factors, and patient-reported medication non-adherence were analyzed. KEY RESULTS: Of 405 patients, 173 (42.7 %) reported medication non-adherence. Factors associated with non-adherence in bivariate analysis included younger age, non-white race, having less than 12 years of education, smoking, financial insecurity, identifying as nervous or tense, higher life chaos score, greater worry about having a myocardial infarction, and greater worry about having a stroke. Using multivariable modeling, we determined that age (OR 0.97 per additional year, 95 % CI, 0.95-0.99), life chaos (OR 1.06 per additional point, 95 % CI, 1.00-1.11), and worry about stroke (OR 1.12 per additional point, 95 % CI, 1.01-1.25) remained significantly associated with self-reported medication non-adherence. CONCLUSIONS: We found that worry about having a stroke, higher life chaos, and younger age were all significantly associated with self-reported medication non-adherence in patients with cardiovascular disease and a history of myocardial infarction. Further research exploring these factors as targets for intervention is needed, as is additional research examining modifiable causes of medication non-adherence among patients with cardiovascular disease.

The purpose of the study was to determine the knowledge and use of antiretroviral treatment (ART) among pregnant women attending health centres in Amathole district, Eastern Cape, South Africa. The study involved a non-probability sample of 70 HIV positive pregnant women on antiretrovirals attending antenatal care clinic in the tertiary hospital in Buffalo City Metropolitan, Eastern Cape, South Africa. A self- designed questionnaire was used as an instrument for data collection. About 99% participants were able tofollow up ART therapy regimen and inform about the importance of taking treatment (ART) regularly, 77% side effects and drug interactions of the drugs (ART) while 31% never heard about the side effects of the drugs and its interactions. About 97% approved the use of ART, while 3% disapproved them. Majority of participants 50% felt healthy ever since they took ART, 32% gained more weight after starting ART and 18% experienced nofrequent illnesses. Also, majority (97%) of the participants were optimistic about prevention of their unborn child by ART, while 3% were not sure about prevention of their unborn child. HIV positive pregnant women on ART exhibited a good knowledge and use of ART. This is encouraging and should be sustained by continuous community awareness campaigns to empower the communities about HIV/AIDS, prevention to mother to child transmission programme and ART and extensive training of health care providers.

The importance and utility of treatment manuals is controversial, especially with respect to how rigidly they should be implemented. This study examined therapist adherence across the course of CBT and how several patient characteristics influence the association between adherence and outcome. Patients diagnosed with panic disorder with agoraphobia (n = 220, 72.7% female, average age of 34.9 years) were treated in one of two CBT variations: with (T+) and without (T-) explicit therapist-guided exposure. Although adherence did not crucially influence outcome at a global level, results suggest that symptom severity and patients' motivation to continue treatment interacted with adherence to predict outcome. Importantly, these effects differed across timing and treatment conditions. Our findings showed the benefits of individualising the implementation of the treatment manual. [ABSTRACT FROM AUTHOR]

Background Poor adherence to medication can lead to suboptimal outcomes, and is reported to occur frequently. Pharmacists in some countries are funded to support the appropriate use of medications in patients and enhance medication adherence, by providing services such as Medicines Use Review (MUR). Objective To describe and investigate factors that may influence patients' knowledge and perceptions of and adherence to medications as determined during MUR. Setting Community pharmacies in a locality in New Zealand. Method Following consent from five MUR service providers, records of patients' MUR consultations conducted between November 2007 and December 2011 were retrospectively reviewed for information on patients, services, and outcomes. Using multilevel mixed-effects logistic regression, factors that predicted the providers' score of the patients' medication knowledge, and the patients' score of their adherence to and perceptions of medications, were investigated. Main outcome measure patients' knowledge, perceptions and adherence scores. Results A total of 353 MUR patients' records were evaluated. The median (IQR) age of patients was 73 (63-81) years. About 41.1 % of patients were Māori. A total of 204 (57.8 %) patients had two MUR consultations and only 53 (15 %) had four. The mean score of patients' knowledge, perceptions of, and adherence to medications were found to increase in each visit which suggests that adherence support by pharmacists might improve patients' outcomes. Females had higher medication knowledge scores than males (OR 3.09, 95 % CI 1.29-7.44). There was some evidence to suggest Māori had lower scores for knowledge of medications than non-Māori (OR 0.092, 95 % CI 0.02-0.36). In addition, longer duration in the program predicted better scores for medication knowledge, adherence and perceptions of medications. Conclusions MUR was found to have the potential to improve the scores of patients' knowledge and perceptions of and adherence to medicines, and factors such as gender, ethnicity and longer duration in the services were found to predict these outcomes.

OBJECTIVE Suboptimal adherence to diabetes medications is prevalent and associated with unfavorable health outcomes, but it remains unclear what intervention content is necessary to effectively promote medication adherence in diabetes. In other disease contexts, the Information-Motivation-Behavioral skills (IMB) model has effectively explained and promoted medication adherence and thus may have utility in explaining and promoting adherence to diabetes medications. We tested the IMB model's hypotheses in a sample of adults with type 2 diabetes. RESEARCH DESIGN AND METHODS Participants (N = 314) completed an interviewer-administered survey and A1C test. Structural equation models tested the effects of diabetes medication adherence-related information, motivation, and behavioral skills on medication adherence and the effect of medication adherence on A1C. RESULTS The IMB elements explained 41% of the variance in adherence, and adherence explained 9% of the variance in A1C. As predicted, behavioral skills had a direct effect on adherence (β = 0.59; P < 0.001) and mediated the effects of information (indirect effect 0.08 [0.01-0.15]) and motivation (indirect effect 0.12 [0.05-0.20]) on adherence. Medication adherence significantly predicted glycemic control (β = -0.30; P < 0.001). Neither insulin status nor regimen complexity was associated with adherence, and neither moderated associations between the IMB constructs and adherence. CONCLUSIONS The results support the IMB model's predictions and identify modifiable and intervenable determinants of diabetes medication adherence. Medication adherence promotion interventions may benefit from content targeting patients' medication adherence-related information, motivation, and behavioral skills and assessing the degree to which change in these determinants leads to changes in medication adherence behavior.

Abstract: Maximizing HIV treatment adherence is critical in efforts to optimize health outcomes and to prevent further HIV transmission. The Balance Project intervention uses cognitive behavioral approaches to improve antiretroviral medication adherence through promoting adaptive coping with medication side effect and distress related to HIV. This 5-session intervention has been documented to prevent nonadherence among persons living with HIV who experience high levels of distress associated with their antiretroviral medication side effects. We describe the theoretical underpinnings of the intervention, provide details of the training and session protocols with a case example, and discuss implications for future applications of the intervention in both research and clinical settings.

Abstract: Rising rates of human immunodeficiency virus (HIV) infection among adolescents and young adults underscore the importance of interventions for this population. While the morbidity and mortality of HIV has greatly decreased over the years, maintaining high rates of adherence is necessary to receive optimal medication effects. Few studies have developed interventions for adolescents and young adults and none have specifically been developed for sexual minority (lesbian, gay, and bisexual; LGB) youth. Guided by an evidence-based adult intervention and adolescent qualitative interviews, we developed a multicomponent, technology-enhanced, customizable adherence intervention for adolescents and young adults for use in a clinical setting. The two cases presented in this paper illustrate the use of the five-session positive strategies to enhance problem solving (Positive STEPS) intervention, based on cognitive-behavioral techniques and motivational interviewing. We present a perinatally infected heterosexual woman and a behaviorally infected gay man to demonstrate the unique challenges faced by these youth and showcase how the intervention can be customized. Future directions include varying the number of intervention sessions based on mode of HIV infection and incorporating booster sessions. [Copyright &y& Elsevier]

The article focuses on a study on the comparison of adherence and persistence associated with the use of nebivolol and hydrochlorothiazide (HCTZ) in the treatment of hypertension.

Objective: The progression of HIV infection depends not only on the combination of drugs and adherence to the Anti Retroviral therapy (ART), but also on various other factors. The survival of an HIV patient depends on interaction of these factors with the therapy. Material and Methods: The parametric approach with and without covariates have been used to analyze the survival data of HIV/AIDS patients. When covariates are not considered, survival distributions are fitted and best one chosen. The inclusion of covariates is analyzed using Censored Generalized Poisson Regression Model (CGPR). Results: For a retrospective right censored data of 1689 HIV/AIDS patients undergoing ART at the Ram Manohar Lohia Hospital, New Delhi, India, appropriate survival distributions in the absence of covariates are fitted. Using the Akaike Information Criterion, Gamma distribution is found to be the distribution of best fit. Assuming Gamma survival distribution with right censored survival time data, the mean survival time of AIDS patients using the method of maximum likelihood is found to be 11.14 years. Also, CGPR model for estimating the survival time while accounting for the impact of cofactors is used for the first time on the AIDS dataset. Conclusion: The advantage of using a CGPR model over the gamma right censored distribution is that the mean survival time of the AIDS patient undergoing ART can be estimated in the presence of significant prognostic factors. Using this model, age, gender, smoking status, alcoholism, WHO staging, improvement in CD4 count, opportunistic infections, number of visits and weight at initiation of ART are identified as significant prognostic factors effecting the survival time. On averaging the predicted survival times based on CGPR model, the mean survival time of AIDS patients on ART is found to be 12.12 years. [ABSTRACT FROM AUTHOR]

Background. High rates of second-line antiretroviral treatment (ART) failure are reported. The association with resistance and nonadherence on switching to second-line ART requires clarification.Methods. Using prospectively collected data from patients in South Africa, we constructed a cohort of patients switched to second-line ART (1 January 2003 through 31 December 2008). Genotyping and drug concentrations (lamivudine, nevirapine, and efavirenz) were measured on stored samples preswitch. Their association with viral load (VL) <400 copies/mL by 15 months was assessed using modified Poisson regression.Results. One hundred twenty-two of 417 patients (49% male; median age, 36 years) had genotyping (n = 115) and/or drug concentrations (n = 80) measured. Median CD4 count and VL at switch were 177 cells/µL (interquartile range [IQR], 77–263) and 4.3 log10 copies/mL (IQR, 3.8–4.7), respectively. Fifty-five percent (n = 44/80) had subtherapeutic drug concentrations preswitch. More patients with therapeutic vs subtherapeutic ART had resistance (n = 73): no major mutations (3% vs 51%), nonnucleoside reverse transcriptase inhibitor (94% vs 44%), M184V/I (94% vs 26%), and ≥1 thymidine analogue mutations (47% vs 18%), all P = .01; and nucleoside reverse transcriptase inhibitor (NRTI) cross-resistance mutations (26% vs 13%, P = .23). Following switch, 68% (n = 83/122) achieved VL <400 copies/mL. Absence of NRTI mutations and subtherapeutic ART preswitch were associated with failure to achieve VL <400 copies/mL.Conclusions. Nonadherence, suggested by subtherapeutic ART with/without major resistance mutations, significantly contributed to failure when switching regimen. Unresolved nonadherence, not NRTI resistance, drives early second-line failure. [ABSTRACT FROM AUTHOR]
