Effective communication is a prerequisite for any successful encounter between patient and provider. Nevertheless, it is unclear how/where communication can impact/affect adherence to ...antihypertensive medication, and maintenance of lifestyle changes to control blood pressure targets. Poor physician communication is correlated with a higher risk of treatment nonadherence. Given the high rates of hypertension globally, this review serves to enlighten aspects of the communication exchange from a provider, context, and patient perspective. Relevant articles were analyzed to assess barriers, solutions, and optimizations for communication with hypertensive patients. To support the findings, a model of communication in the context of hypertension treatment is presented, which comprises three phasescomprehension and acceptance, translation into action, and long-term retention. Secondly, an analysis of care providers (bedside manner, verbal/nonverbal communication, empathy and sex, time, knowledge base), context (format and tailoring of the message, and physical environment), and patient-related factors (sex, socio-economic status, language and health literacy, culture, age, psychological factors) were assessed in relation to hypertension. Current literature is limited regarding reciprocal communication, adaptive packaging of messages, and active verification of effective communication. To improve communication, hypertension care programs could benefit from better communication training, more team-based approaches, and flexible tools based on information technology.
Male sexual behavior influences the rates of cervical dysplasia and invasive cervical cancer, as well as male human papillomavirus
(HPV) infection and disease. Unfortunately, little is known ...regarding male HPV type distribution by age and across countries.
In samples combined from the coronal sulcus, glans penis, shaft, and scrotum of 1,160 men from Brazil, Mexico, and the United
States, overall HPV prevalence was 65.2%, with 12.0% oncogenic types only, 20.7% nononcogenic types only, 17.8% both oncogenic
and nononcogenic, and 14.7% unclassified infections. Multiple HPV types were detected in 25.7% of study participants. HPV
prevalence was higher in Brazil (72.3%) than in the United States (61.3%) and Mexico (61.9%). HPV16 (6.5%), HPV51 (5.3%),
and HPV59 (5.3%) were the most commonly detected oncogenic infections, and HPV84 (7.7%), HPV62 (7.3%), and HPV6 (6.6%) were
the most commonly detected nononcogenic infections. Overall HPV prevalence was not associated with age. However, significant
associations with age were observed when specific categories of HPV, nononcogenic, and unclassified HPV infections were considered.
Studies of HPV type distribution among a broad age range of men from multiple countries is needed to fill the information
gap internationally with respect to our knowledge of HPV infection in men. (Cancer Epidemiol Biomarkers Prev 2008;17(8):2036–43)
To understand hypertensive patients' perspectives regarding blood pressure and hypertension treatment, this qualitative study applied semistructured interviews of hypertensive patients. Participants ...were recruited from two hypertension clinics at the University of Alberta in Edmonton, Canada. To be eligible for inclusion, patients had to be aged 18 years or older, diagnosed with hypertension by a healthcare provider, and currently taking an antihypertensive medication. Participants were stratified in the analysis according to blood pressure control. Twenty-six patients (mean age 57; 62% female) were interviewed, of which 42% were on target and 58% were not. Three underlying themes emerged from the interviews: (a) knowledge of blood pressure relating to diagnosis and management and control of hypertension, (b) integration of hypertension management into daily routine, and (c) feelings and beliefs of wellness. None of the above themes were associated with better control. Knowledge gaps were found, which emphasize the need for further patient education and physician training. Feelings and beliefs of wellness, and not knowledge, were important factors in home assessment of blood pressure. The absence of connections between control of hypertension and the identified domains indicates that current approaches could benefit from the development of a more personalized approach for education and communication.
To assess Human Papillomavirus (HPV) type distribution among men ages 18 years and older recruited from three different countries utilizing a common protocol for sampling HPV detection, and to ...evaluate whether HPV detection differs by age and country. MATERIAL AD METHODS: The study protocol includes a pre-enrollment run-in visit, a baseline (enrollment) visit, and nine additional visits after enrollment scheduled six months apart. For this analysis, the first 1160 men who completed both the run-in and baseline visit were included. To maximize sampling and prevent fraying of applicators, three different applicators were utilized to sample the external genitalia of participants among different anatomic sites. These samples were later combined to form a single sample for the detection of HPV using polymerase chain reaction (PCR) for amplification of a fragment of the HPV L1 gene.
Among 1160 men from Brazil, Mexico, and the United States (U.S.), overall HPV prevalence was 65.2%; with 12.0% oncogenic types only, 20.7% non-oncogenic types only, 17.8% both oncogenic and non-oncogenic, and 14.7% unclassified infections. Multiple HPV types were detected in 25.7% of study participants. HPV prevalence was higher in Brazil (72.3%) than in the U.S. (61.3%) and Mexico (61.9%). HPV 16 (6.5%), 51 (6.5%), and 59 (5.3%) were the most commonly detected oncogenic infections, and HPV 84 (7.7%), 62 (7.3%), and 6 (6.6%) were the most commonly detected non-oncogenic infections. Overall HPV prevalence was not associated with age. However, significant associations with age were observed when specific categories of oncogenic, non-oncogenic, and unclassified HPV infections were considered.
Studies of HPV type distribution among a broad age range of men from multiple countries is needed to fill the information gap internationally with respect to our knowledge of HPV infection in men.
Allergy is diagnosed from typical symptoms, and tests are performed to incriminate the suspected precipitant. Skin prick tests (SPTs) are commonly performed, inexpensive, and give immediate results. ...Laboratory tests (ImmunoCAP) for serum allergen-specific IgE antibodies are usually performed more selectively. The immuno-solid phase allergen chip (ISAC) enables testing for specific IgE against multiple allergen components in a multiplex assay.
We retrospectively analysed clinic letters, case notes, and laboratory results of 118 patients attending the National Adult Allergy Service at the University Hospital of Wales who presented diagnostic difficulty, to evaluate which testing strategy (SPT, ImmunoCAP, or ISAC) was the most appropriate to use to confirm the diagnosis in these complex patients, evaluated in a "real-life" clinical service setting.
In patients with nut allergy, the detection rates of SPTs (56%) and ISAC (65%) were lower than those of ImmunoCAP (71%). ISAC had a higher detection rate (88%) than ImmunoCAP (69%) or SPT (33%) in the diagnosis of oral allergy syndrome. ImmunoCAP test results identified all 9 patients with anaphylaxis due to wheat allergy (100%), whereas ISAC was positive in only 6 of these 9 (67%).
In this difficult diagnostic group, the ImmunoCAP test should be the preferred single test for possible allergy to nuts, wheat, other specific foods, and anaphylaxis of any cause. In these conditions, SPT and ISAC tests give comparable results. The most useful single test for oral allergy syndrome is ISAC, and SPT should be the preferred test for latex allergy.
An association between antibody deficiency and clozapine use in individuals with schizophrenia has recently been reported. We hypothesised that if clozapine-associated hypogammaglobulinaemia was ...clinically relevant this would manifest in referral patterns.
Retrospective case note review of patients referred and assessed by Immunology Centre for Wales (ICW) between January 2005 and July 2018 with extraction of clinical and immunological features for individuals with diagnosis of schizophrenia-like illness.
1791 adult patients were assessed at ICW during this period; 23 patients had a psychiatric diagnosis of schizophrenia or schizoaffective disorder. Principal indications for referral were findings of low calculated globulin and immunoglobulins. Clozapine was the single most commonly prescribed antipsychotic (17/23), disproportionately increased relative to reported use in the general schizophrenia population (OR 6.48, 95% CI: 1.79 to 23.5). Clozapine therapy was noted in 6/7 (86%) of patients subsequently requiring immunoglobulin replacement therapy (IgRT). Marked reduction of class-switched memory B cells (CSMB) and plasmablasts were observed in clozapine-treated individuals relative to healthy age-matched controls. Clozapine duration is associated with CSMB decline. One patient discontinued clozapine, with gradual recovery of IgG levels without use of IgRT.
Our findings are consistent with enrichment of clozapine-treatment within schizophrenic individuals referred for ICW assessment over the last 13 years. These individuals displayed clinical patterns closely resembling the primary immunodeficiency common variable immunodeficiency, however appears reversible on drug cessation. This has diagnostic, monitoring and treatment implications for psychiatry and immunology teams and directs prospective studies to address causality and the wider implications for this patient group.
Welsh immunodeficient patients on immunoglobulin replacement therapy (IgRT) who were considered high risk for severe coronavirus disease 2019 (COVID-19) were directed to shield. Consequently, ...patients receiving hospital-based intravenous immunoglobulin (IVIg) quickly transitioned to home-based self-administered subcutaneous immunoglobulin (SCIg). This evaluation aimed to assess patients' perceptions and experiences and laboratory outcomes of emergency IgRT transition during COVID-19.
A quick transition from in-hospital IVIg to home-based rapid push SCIg is achievable, however, patient IgRT administration preference remains key outside of emergency shielding measures.
Subjective self-reported experiences ( n = 23) and objective immunoglobulin G (IgG) concentration ( n = 28) assessments were prospectively collected from patients pre/post-IgRT switch. In total, 41/55 (75%) patients transitioned from IVIg to rapid push SCIg and all completed training to self-administer subcutaneously within 24 days. Twenty-two percent ( n = 5) of patients preferred SCIg and 35% ( n = 8) wanted to return to hospital-based IVIg at 6 weeks post-transition. Mean IgG levels were similar pre vs. post-SCIg switch (10.3 g/l vs. 10.6 g/l, respectively). Patients reported greater infection anxiety during COVID-19 and adapted behaviours to mitigate risk. Although a third of patients wished to return to IVIg following cessation of shielding, over time the percentage electing to remain on SCIg rose from 22% to 59%.
Schizophrenia affects 1% of the population. Clozapine is the only medication licensed for treatment-resistant schizophrenia and is intensively monitored to prevent harm from neutropenia. Clozapine is ...also associated with increased risk of pneumonia although the mechanism is poorly understood.AimsTo investigate the potential association between clozapine and antibody deficiency.
Patients taking clozapine and patients who were clozapine-naive and receiving alternative antipsychotics were recruited and completed a lifestyle, medication and infection-burden questionnaire. Serum total immunoglobulins (immunoglobulin (Ig)G, IgA, IgM) and specific IgG antibodies to haemophilus influenzae type B, tetanus and IgG, IgA and IgM to pneumococcus were measured.
Immunoglobulins were all significantly reduced in the clozapine-treated group (n = 123) compared with the clozapine-naive group (n = 111). Odds ratios (ORs) for a reduction in clozapine:control immunoglobulin values below the fifth percentile were IgG, OR = 6.00 (95% CI 1.31-27.44); IgA, OR = 16.75 (95% CI 2.18-128.60); and IgM, OR = 3.26 (95% CI 1.75-6.08). These findings remained significant despite exclusion of other potential causes of hypogammaglobulinaemia. In addition, duration on clozapine was associated with decline in IgG. A higher proportion of the clozapine-treated group reported taking more than five courses of antibiotics in the preceding year (5.3% (n = 5) versus 1% (n = 1).
Clozapine use was associated with significantly reduced immunoglobulin levels and an increased proportion of patients using more than five antibiotic courses in a year. Antibody testing is not included in existing clozapine monitoring programmes but may represent a mechanistic explanation and modifiable risk factor for the increased rates of pneumonia and sepsis-related mortality previously reported in this vulnerable cohort.Declaration of interestS.J. has received support from CSL Behring, Shire, LFB, Biotest, Binding Site, Sanofi, GSK, UCB Pharma, Grifols, BPL SOBI, Weatherden, Zarodex and Octapharma for projects, advisory boards, meetings, studies, speaker and clinical trials.
