Patient Reported Sexual Adaptation Following Prostate Cancer Treatment: An Analysis of Related Variables and Sexual Outcomes Associated with Sexual Adaptation Styles.

Sexual concerns after prostate cancer (PCa) treatment are high. Flexible coping is a crucial element to maintaining sexual activity after PCa and improves adaptation outcomes. We aimed to identify potential sexual adaptation styles reported by men following PCa treatment, and to assess relationships among associated variables and outcomes. Individuals (n = 223) with PCa treatment history (e.g., radical prostatectomy [n = 165, 74.0%], external beam radiation [n = 83, 37.2%], hormone/androgen deprivation therapy [n = 83, 37.2%]), completed an online survey assessing sexual variables and processes of sexual adaptation. Using a combination of inductive and deductive coding, open-ended responses were thematically analyzed and grouped into sexual adaptation styles. Factors potentially associated with sexual adaptation styles (e.g., age, perceived partner involvement, co-morbidities, relationship duration, time since PCa treatment, desire for physical affection, depression, relationship adjustment) were tested using multinomial logistic regression. Outcomes of sexual well-being (sexual distress, sexual bother, sexual satisfaction) and relationship adjustment were compared against each sexual adaptation style using a multivariate analysis of variance. Sexual activity status and satisfaction with the adaptation process was assessed across the sexual adaptation styles using a chi-square analysis and post-hoc tests. Two distinct categories were identified: those who had Adapted (n = 185) and those who had Not Adapted (n = 38). Four sexual adaptation styles emerged in the adapted category: Relationship Renegotiation (n = 53) and Sexual Renegotiation (n = 47), which were couples-focused styles, and Acceptance/Resignation (n = 34) and Masturbation/Erection (n = 48), which were individual-focused styles. Participants who could not be categorized as one style, but rather met several, were identified as Mixed (n = 3). Higher rates of depression, lower relationship adjustment, lack of sexual activity, and greater dissatisfaction with the adaptation process were observed for Not Adapted participants. Participants engaged in any type of adaptation style fared better than those who had Not Adapted. Couples-focused styles tended to emphasize renegotiation, including a changed perspective on the expression of the relationship. Perceived direct engagement of the partner facilitated adaptation and emphasized engagement with flexible coping, either through redefining priorities or ways of being sexual. Individual-focused styles emphasized pre-cancer erectile function, and either aimed to return to capacity for penetrative sexual activity or accepted its inaccessibility and largely an abandonment of partnered sexual activity.

Large variation in radiation dose for routine abdomen CT: reasons for excess and easy tips for reduction.

OBJECTIVE: To characterize the use and impact of radiation dose reduction techniques in actual practice for routine abdomen CT. METHODS: We retrospectively analyzed consecutive routine abdomen CT scans in adults from a large dose registry, contributed by 95 hospitals and imaging facilities. Grouping exams into deciles by, first, patient size, and second, size-adjusted dose length product (DLP), we summarized dose and technical parameters and estimated which parameters contributed most to between-protocols dose variation. Lastly, we modeled the total population dose if all protocols with mean size-adjusted DLP above 433 or 645 mGy-cm were reduced to these thresholds. RESULTS: A total of 748,846 CTs were performed using 1033 unique protocols. When sorted by patient size, patients with larger abdominal diameters had increased dose and effective mAs (milliampere seconds), even after adjusting for patient size. When sorted by size-adjusted dose, patients in the highest versus the lowest decile in size-adjusted DLP received 6.4 times the average dose (1680 vs 265 mGy-cm) even though diameter was no different (312 vs 309 mm). Effective mAs was 2.1-fold higher, unadjusted CTDIvol 2.9-fold, and phase 2.5-fold for patients in the highest versus lowest size-adjusted DLP decile. There was virtually no change in kV (kilovolt). Automatic exposure control was widely used to modulate mAs, whereas kV modulation was rare. Phase was the strongest driver of between-protocols variation. Broad adoption of optimized protocols could result in total population dose reductions of 18.6-40%. CONCLUSION: There are large variations in radiation doses for routine abdomen CT unrelated to patient size. Modification of kV and single-phase scanning could result in substantial dose reduction. CLINICAL RELEVANCE: Radiation dose-optimization techniques for routine abdomen CT are routinely under-utilized leading to higher doses than needed. Greater modification of technical parameters and number of phases could result in substantial reduction in radiation exposure to patients. KEY POINTS: • Based on an analysis of 748,846 routine abdomen CT scans in adults, radiation doses varied tremendously across patients of the same size and optimization techniques were routinely under-utilized. • The difference in observed dose was due to variation in technical parameters and phase count. Automatic exposure control was commonly used to modify effective mAs, whereas kV was rarely adjusted for patient size. Routine abdomen CT should be performed using a single phase, yet multi-phase was common. • kV modulation by patient size and restriction to a single phase for routine abdomen indications could result in substantial reduction in radiation doses using well-established dose optimization approaches.

Simulation as a key training method for inculcating public health leadership skills: a mixed methods study.

Background: Successful management of public health challenges requires developing and nurturing leadership competencies. We aimed to evaluate the effectiveness of training simulations to assess public health leadership and decision-making competencies during emergencies as an effective learning and training method. Methods: We examined the effects of two simulation scenarios on public health school students in terms of their experience (compared to face-to-face learning) and new skills acquired for dealing with similar emergent situations in the future. A mixed-methods design included developing a validated and pre-tested questionnaire with open-and closed-ended questions that examined the simulation impact and the degree of student satisfaction with the conditions in which it was conducted. Semi-structured in-depth interviews were conducted with the students after going through the simulations. The questionnaire results were evaluated using descriptive analytics. The interviews were analyzed using thematic analyses. All data were collected during June 2022. Results: The questionnaire results indicate that students strengthened their interpersonal communication skills and learned about the importance of listening to the opinions of others before formulating their positions. Four themes emerged from 16 in-depth interviews, according to Kolb's experimental learning cycle. Students emphasized the effectiveness of experiential learning versus traditional classroom learning. The simulation scenarios were felt to realistically convey critical issues regarding leadership, decision-making, and teamwork challenges. They effectively conveyed the importance of building a culture of conducting substantive and respectful discussions. Conclusion: Simulation is a powerful pedagogical training tool for public health leadership competencies. Simulations were seen to be advantageous over face-to-face learning in imparting a range of leadership skills and hands-on practice. We recommend integrating simulations in all public health leadership training programs.

Reduction in Chest CT Severity and Improved Hospital Outcomes in SARS-CoV-2 Omicron Compared with Delta Variant Infection.

Background The SARS-Cov-2 Omicron variant demonstrates rapid spread but reduced disease severity. Studies evaluating lung imaging findings of Omicron infection versus non-Omicron infection remain lacking. Purpose To compare the Omicron variant with the SARS-CoV-2 Delta variant according to their chest CT radiologic pattern, biochemical parameters, clinical severity, and hospital outcomes after adjusting for vaccination status. Materials and Methods This retrospective study included hospitalized adult patients with reverse transcriptase-polymerase chain reaction test results positive for SARS-CoV-2, with CT pulmonary angiography performed within 7 days of admission between December 1, 2021, and January 14, 2022. Multiple readers performed blinded radiologic analyses that included RSNA CT classification, chest CT severity score (CTSS) (range, 0 [least severe] to 25 [most severe]), and CT imaging features, including bronchial wall thickening. Results A total of 106 patients (Delta group, n = 66; Omicron group, n = 40) were evaluated (overall mean age, 58 years ± 18 [SD]; 58 men). In the Omicron group, 37% of CT pulmonary angiograms (15 of 40 patients) were categorized as normal compared with 15% (10 of 66 patients) of angiograms in the Delta group (P = .016). A generalized linear model was used to control for confounding variables, including vaccination status, and Omicron infection was associated with a CTSS that was 7.2 points lower than that associated with Delta infection (ß = -7.2; 95% CI: -9.9, -4.5; P < .001). Bronchial wall thickening was more common with Omicron infection than with Delta infection (odds ratio [OR], 2.4; 95% CI: 1.01, 5.92; P = .04). A booster shot was associated with a protective effect for chest infection (median CTSS, 5; IQR, 0-11) when compared with unvaccinated individuals (median CTSS, 11; IQR, 7.5-14.0) (P = .03). The Delta variant was associated with a higher OR of severe disease (OR, 4.6; 95% CI: 1.2, 26; P = .01) and admission to a critical care unit (OR, 7.0; 95% CI: 1.5, 66; P = .004) when compared with the Omicron variant. Conclusion The SARS-CoV-2 Omicron variant was associated with fewer and less severe changes on chest CT images compared with the Delta variant. Patients with Omicron infection had greater frequency of bronchial wall thickening but less severe disease and improved hospital outcomes when compared with patients with Delta infection. © RSNA, 2022 Online supplemental material is available for this article.

Program Evaluation of a Class Addressing Psychosocial Topics in Preparation for Hematopoietic Cell Transplantation: a Brief Report.

Patients undergoing hematopoietic cell transplantation (HCT) and their caregivers can experience psychosocial complications pre-, during, and post-transplant. To meet the needs of the most patients and caregivers, a class was developed to prepare patients and caregivers to prevent and manage common psychosocial challenges. We evaluated the feasibility and acceptability of the class over a 5-month pilot period. Attendance in this class became part of standard pre-transplant care. Attendees were invited to complete a questionnaire (Likert-scale and open-ended questions) to evaluate the feasibility and acceptability of this class. Data were collected over a 5-month period. Descriptive analysis was completed. Patients (n = 41) and caregivers (n = 40) were satisfied to very satisfied with the class. Patients (80%) and caregivers (65%) reported that the class met their expectations, with several describing it as worthwhile and informative. Information relating to finances and benefits were considered most helpful, followed by emotional support resources. Patients (73%) and caregivers (93%) reported that they would recommend the class to others. This education class should be provided as early as possible to ensure that psychosocial needs are addressed. Future research initiatives include further assessing the perspectives of patients, clinicians, and other stakeholders; evaluating delivery methods; and collaborating with other centers.

Emerging lessons from the COVID-19 pandemic about the decisive competencies needed for the public health workforce: A qualitative study.

The global COVID-19 crisis exposed the critical need for a highly qualified public health workforce. This qualitative research aimed to examine public health workforce competencies needed to face COVID-19 challenges and identify the gaps between training programs and the competency demands of real-world disasters and pandemics. Through a sample of thirty-one participant qualitative interviews, we examined the perspectives of diverse stakeholders from lead public health organizations in Israel. Grounded Theory was used to analyze the data. Six themes emerged from the content analysis: public health workforce's low professional status and the uncertain future of the public health workforce; links between the community and Higher Education institutions; the centrality of communication competencies; need to improve health promotion; the role of leadership, management, and partnership, and innovation in public health coherence. Increasing the attractiveness of the profession, professional and financial support, and improving the working conditions to ensure a sustainable and resilient PH system were deemed necessary. This paper describes and cultivates new knowledge and leadership skills among public health professionals, and lays the groundwork for future public health leadership preparedness programs.

Diagnostic reference levels and median doses for common clinical indications of CT: findings from an international registry.

OB JECTIVES: The European Society of Radiology identified 10 common indications for computed tomography (CT) as part of the European Study on Clinical Diagnostic Reference Levels (DRLs, EUCLID), to help standardize radiation doses. The objective of this study is to generate DRLs and median doses for these indications using data from the UCSF CT International Dose Registry. METHODS: Standardized data on 3.7 million CTs in adults were collected between 2016 and 2019 from 161 institutions across seven countries (United States of America (US), Switzerland, Netherlands, Germany, UK, Israel, Japan). DRLs (75th percentile) and median doses for volumetric CT-dose index (CTDIvol) and dose-length product (DLP) were assessed for each EUCLID category (chronic sinusitis, stroke, cervical spine trauma, coronary calcium scoring, lung cancer, pulmonary embolism, coronary CT angiography, hepatocellular carcinoma (HCC), colic/abdominal pain, appendicitis), and US radiation doses were compared with European. RESULTS: The number of CT scans within EUCLID categories ranged from 8,933 (HCC) to over 1.2 million (stroke). There was greater variation in dose between categories than within categories (p < .001), and doses were significantly different between categories within anatomic areas. DRLs and median doses were assessed for all categories. DRLs were higher in the US for 9 of the 10 indications (except chronic sinusitis) than in Europe but with a significantly higher sample size in the US. CONCLUSIONS: DRLs for CTDIvol and DLP for EUCLID clinical indications from diverse organizations were established and can contribute to dose optimization. These values were usually significantly higher in the US than in Europe. KEY POINTS: • Registry data were used to create benchmarks for 10 common indications for CT identified by the European Society of Radiology. • Observed US radiation doses were higher than European for 9 of 10 indications (except chronic sinusitis). • The presented diagnostic reference levels and median doses highlight potentially unnecessary variation in radiation dose.

Identifying the Gaps Between Public Health Training and Practice: A Workforce Competencies Comparative Analysis.

Objectives: The study aimed to generate insights on how best to enhance the compatibility between Public Health training program competencies and the implementation of competencies required by employers to address current and emerging public health needs. Methods: A survey adapted from the WHO-ASPHER Competency Framework for the Public Health Workforce was conducted online among Israeli public health managers from August to November 2021. The survey was formulated to mirror Essential Public Health Operations. Forty-nine managers participated (37.6% response rate) in an assessment of 44 public health competencies and the core organizational public health operations. Results: Analysis of Essential Public Health Operations revealed a notably high deficiency reported for Advocacy Communication and Social Mobilization for health competencies. Collaborations and Partnership and, Leadership and System Thinking were the most reported insufficient competencies, particularly in health departments and research institutes. Governmental offices reported Organizational Literacy and Adaptability competencies being deficient. Deficiencies were more impactful as the level of expertise increased. Conclusion: There is a clear need for public health professionals to acquire versatile and innovative competencies in response to the ever-changing health threats.

The Future Public Health Workforce in a Changing World: A Conceptual Framework for a European-Israeli Knowledge Transfer Project.

Health services quality and sustainability rely mainly on a qualified workforce. Adequately trained public health personnel protect and promote health, avert health disparities, and allow rapid response to health emergencies. Evaluations of the healthcare workforce typically focus on physicians and nurses in curative medical venues. Few have evaluated public health workforce capacity building or sought to identify gaps between the academic training of public health employees and the needs of the healthcare organizations in which they are employed. This project report describes the conceptual framework of "Sharing European Educational Experience in Public Health for Israel (SEEEPHI): harmonization, employability, leadership, and outreach"-a multinational Erasmus+ Capacity Building in Higher Education funded project. By sharing European educational experience and knowledge, the project aims to enhance professionalism and strengthen leadership aspects of the public health workforce in Israel to meet the needs of employers and the country. The project's work packages, each jointly led by an Israeli and European institution, include field qualification analysis, mapping public health academic training programs, workforce adaptation, and building leadership capacity. In the era of global health changes, it is crucial to assess the capacity building of a well-qualified and competent workforce that enables providing good health services, reaching out to minorities, preventing health inequalities, and confronting emerging health challenges. We anticipate that the methods developed and the lessons learned within the Israeli context will be adaptable and adoptable by other countries through local and cultural adjustments.

Towards an increased understanding of reminiscence therapy for people with dementia: A narrative analysis.

AIM: Reminiscence therapy is a popular therapeutic intervention for people with dementia. This review set out to provide a better understanding of reminiscence therapy through a deeper analysis of its contents and delivery. METHOD: This review examined 22 studies from the most recent Cochrane review (Woods, B., O'Philbin, L., Farrell, E. M., Spector, A. E., & Orrell, M. (2018). Reminiscence therapy for dementia. Cochrane Database of Systematic Reviews, 3, Article 001120) and addressed the following research questions: (1) What are the components of reminiscence therapy? (2) Who delivers reminiscence therapy? (3) How is reminiscence therapy delivered? (4) Is reminiscence therapy underpinned by a theoretical framework? (5) Is reminiscence therapy delivered according to a programme/model? (6) Are there commonalities in the reminiscence therapy components utilised? Multiple and layered narrative analyses were completed. FINDINGS: Thirteen reminiscence therapy components were identified. 'Memory triggers' and 'themes' were identified as the most common but were found not to be consistently beneficial. Reminiscence therapy was typically delivered in a care setting using a group approach; however, there was no consistency in session composition, intervention duration, as well as the training and supervision provided to facilitators. Operationalisation of theory within reminiscence therapy was not identified. Reminiscence therapy was not consistently delivered according to a programme/model. Lastly, as a result of a small number of studies, the components 'life stages', 'activities' and 'family-only sessions', showed beneficial promise. In summary, this review highlights that reminiscence therapy needs more consistency in content and delivery, in addition to a clear theoretical framework.

The Controversial Role of Fibrosis in Autosomal Dominant Polycystic Kidney Disease.

Autosomal Dominant Polycystic Kidney Disease (ADPKD) is characterized by the progressive growth of cysts but it is also accompanied by diffuse tissue scarring or fibrosis. A number of recent studies have been published in this area, yet the role of fibrosis in ADPKD remains controversial. Here, we will discuss the stages of fibrosis progression in ADPKD, and how these compare with other common kidney diseases. We will also provide a detailed overview of some key mechanistic pathways to fibrosis in the polycystic kidney. Specifically, the role of the 'chronic hypoxia hypothesis', persistent inflammation, Transforming Growth Factor beta (TGFß), Janus Kinase/Signal Transducers and Activators of Transcription (JAK/STAT) and microRNAs will be examined. Evidence for and against a pathogenic role of extracellular matrix during ADPKD disease progression will be provided.

Diagnostic accuracy of initial chest radiograph compared to SARS-CoV-2 PCR in patients with suspected COVID-19.

OBJECTIVE: The chest radiograph (CXR) is the predominant imaging investigation being used to triage patients prior to either performing a SARS-CoV-2 polymerase chain reaction (PCR) test or a diagnostic CT scan, but there are limited studies that assess the diagnostic accuracy of CXRs in COVID-19.To determine the accuracy of CXR diagnosis of COVID-19 compared with PCR in patients presenting with a clinical suspicion of COVID-19. METHODS AND MATERIALS: The CXR reports of 569 consecutive patients with a clinical suspicion of COVID-19 were reviewed, blinded to the PCR result and classified into the following categories: normal, indeterminate for COVID-19, classic/probable COVID-19, non-COVID-19 pathology, and not specified. Severity reporting and reporter expertise were documented. The subset of this cohort that had CXR and PCR within 3 days of each other were included for further analysis for diagnostic accuracy. RESULTS: Classic/probable COVID-19 was reported in 29% (166/569) of the initial cohort. 67% (382/569) had PCR tests. 344 patients had CXR and PCR within 3 days of each other. Compared to PCR as the reference test, initial CXR had a 61% sensitivity and 76% specificity in the diagnosis of COVID-19. CONCLUSION: Initial CXR is useful as a triage tool with a sensitivity of 61% and specificity of 76% in the diagnosis of COVID-19 in a hospital setting. ADVANCES IN KNOWLEDGE: .Diagnostic accuracy does not differ significantly between specialist thoracic radiologists and general radiologists including trainees following training.There was a 40% prevalence of PCR positive disease in the cohort of patients (n = 344) having CXR and PCR within 3 days of each other.Classic/probable COVID-19 was reported in 29% of total cohort of patients presenting with clinical suspicion of COVID-19 (n = 569).Initial CXR is useful as a triage tool with a sensitivity of 61% and specificity of 76% in the diagnosis of COVID-19 in a hospital setting.

COVID-19 pneumonia and the masquerades.

During the COVID-19 pandemic, chest CT is frequently used to help with the diagnosis. The classic CT patterns of COVID-19 pneumonia are well-published and recognised among radiologists. However, when there are pre-existing conditions particularly in the elderly population that could mask or result in similar patterns of disease, then the diagnosis is more difficult. This imaging essay highlights the commonly encountered situations including patients with heart failure, other possible infections particularly in the immunodeficient, and when there is trauma to the thorax. We illustrate imaging clues available to the radiologist to either make the diagnosis or at least reduce the differential diagnosis.

Twenty-Four-Hour Ex Vivo Perfusion with Acellular Solution Enables Successful Replantation of Porcine Forelimbs.

BACKGROUND: A critical barrier to successful limb replantation and allotransplantation is the maximum allowable limb ischemia time of 4 to 6 hours. The current gold standard is to preserve amputated limbs on an ice slurry. Experimental machine perfusion has yielded promising results as an alternative. In particular, hypothermic acellular perfusion has enabled preservation of amputated limbs for up to 12 hours thus far. METHODS: Amputated forelimbs of Yorkshire pigs were preserved on static cold storage at 4°C for 4 hours (static cold storage group) or perfused at 8°C for 24 hours (perfusion group) with oxygenated modified STEEN Solution perfusate before replantation. Animals were followed up for 7 days after replantation. RESULTS: Eight animals underwent replantation (cold storage group, n = 4; perfusion group, n = 4). Seventy-five and 100 percent of animals in the static cold storage and perfusion groups survived for 7 days, respectively. Glycogen and adenosine triphosphate remained stable throughout perfusion. Heart and respiratory rate after replantation were increased in the static cold storage group. There was increased damage in muscle biopsy specimens obtained from animals in the static cold storage group after 7 days when compared with those from animals in the perfusion group. CONCLUSIONS: Hypothermic acellular ex vivo perfusion of limbs for up to 24 hours enables tissue preservation comparable to that obtained with conventional static cold storage for 4 hours and may reduce muscle damage and systemic reactions on limb replantation. Translation to human limbs may help improve limb replantation and allotransplantation outcomes.

Needle size for vaccination procedures in children and adolescents.

BACKGROUND: This is an update of a Cochrane Review first published in 2015. The conclusions have not changed.Hypodermic needles of different sizes (gauges and lengths) can be used for vaccination procedures. The gauge (G) refers to the outside diameter of the needle tubing. The higher the gauge number, the smaller the diameter of the needle (e.g. a 23 G needle is 0.6 mm in diameter, whereas a 25 G needle is 0.5 mm in diameter). Many vaccines are recommended for injection into muscle (intramuscularly), although some are delivered subcutaneously (under the skin) and intradermally (into skin). Choosing an appropriate length and gauge of a needle may be important to ensure that a vaccine is delivered to the appropriate site and produces the maximum immune response while causing the least possible harm. Guidelines conflict regarding the sizes of needles that should be used for vaccinating children and adolescents. OBJECTIVES: To assess the effects of using needles of different sizes for administering vaccines to children and adolescents on vaccine immunogenicity (the ability of the vaccine to elicit an immune response), procedural pain, and other reactogenicity events (adverse events following vaccine administration). SEARCH METHODS: We updated our searches of CENTRAL, MEDLINE, Embase, and CINAHL to October 2017. We also searched proceedings of vaccine conferences and two trials registers. SELECTION CRITERIA: Randomised controlled trials evaluating the effects of using hypodermic needles of any gauge or length to administer any type of vaccine to people aged from birth to 24 years. DATA COLLECTION AND ANALYSIS: Three review authors independently extracted trial data and assessed the risk of bias. We contacted trial authors for additional information. We rated the quality of evidence using the GRADE system. MAIN RESULTS: We included five trials involving 1350 participants in the original review. The updated review identified no new trials. The evidence from two small trials (one trial including infants and one including adolescents) was insufficient to allow any definitive statements to be made about the effects of the needles evaluated in the trials on vaccine immunogenicity and reactogenicity.The remaining three trials (1135 participants) contributed data to comparisons between 25 G 25 mm, 23 G 25 mm, and 25 G 16 mm needles. These trials included infants predominantly aged from two to six months undergoing intramuscular vaccination in the anterolateral thigh using the World Health Organization (WHO) injection technique (skin stretched flat, needle inserted at a 90° angle and up to the needle hub in healthy infants). The vaccines administered were combination vaccines containing diphtheria, tetanus, and whole-cell pertussis antigens (DTwP). In some trials, the vaccines also contained Haemophilus influenzae type b (DTwP-Hib) and hepatitis B (DTwP-Hib-Hep B) antigen components.Primary outcomesIncidence of vaccine-preventable diseases: No trials reported this outcome.Procedural pain and crying: Using a wider gauge 23 G 25 mm needle may slightly reduce procedural pain (low-quality evidence) and probably leads to a slight reduction in the duration of crying time immediately after vaccination (moderate-quality evidence) compared with a narrower gauge 25 G 25 mm needle (one trial, 320 participants). The effects are probably not large enough to be clinically relevant.Secondary outcomesImmune response: There is probably little or no difference in immune response, defined in terms of the proportion of seroprotected infants, between use of 25 G 25 mm, 23 G 25 mm, or 25 G 16 mm needles to administer a series of three doses of a DTwP-Hib vaccine at ages two, three, and four months (moderate-quality evidence, one trial, numbers of participants in analyses range from 309 to 402. The immune response to the pertussis antigen was not measured).Severe and non-severe local reactions: 25 mm needles (either 25 G or 23 G) probably lead to fewer severe and non-severe local reactions after DTwP-Hib vaccination compared with 25 G 16 mm needles (moderate-quality evidence, one trial, 447 to 458 participants in analyses). We estimate that one fewer infant will experience a severe local reaction (extensive redness and swelling) after the first vaccine dose for every 25 infants vaccinated with the longer rather than the shorter needle (number needed to treat for an additional beneficial outcome (NNTB) with a 25 G 25 mm needle: 25 (95% confidence interval (CI) 15 to 100); NNTB with a 23 G 25 mm needle: 25 (95% CI 17 to 100)). We estimate that one fewer infant will experience a non-severe local reaction (any redness, swelling, tenderness, or hardness (composite outcome)) at 24 hours after the first vaccine dose for every 5 or 6 infants vaccinated with a 25 mm rather than a 16 mm needle (NNTB with a 25 G 25 mm needle: 5 (95% CI 4 to 10); NNTB with a 23 G 25 mm needle: 6 (95% CI 4 to 13)). The results are similar after the second and third vaccine doses.Using a narrow gauge 25 G 25 mm needle may produce a small reduction in the incidence of local reactions after each dose of a DTwP vaccine compared with a wider gauge 23 G 25 mm needle, but the effect estimates are imprecise (low-quality evidence, two trials, 100 to 459 participants in analyses).Systemic reactions: The comparative effects of 23 G 25 mm, 25 G 25 mm, and 25 G 16 mm needles on the incidence of postvaccination fever and other systemic events such as drowsiness, loss of appetite, and vomiting are uncertain due to the very low quality of the evidence. AUTHORS' CONCLUSIONS: Using 25 mm needles (either 23 G or 25 G) for intramuscular vaccination procedures in the anterolateral thigh of infants using the WHO injection technique probably reduces the occurrence of local reactions while achieving a comparable immune response to 25 G 16 mm needles. These findings are applicable to healthy infants aged two to six months receiving combination DTwP vaccines with a reactogenic whole-cell pertussis antigen component. These vaccines are predominantly used in low- and middle-income countries. The applicability of the findings to vaccines with acellular pertussis components and other vaccines with different reactogenicity profiles is uncertain.

What a difference a year makes: comparing relationships between stressful life events, mood and life satisfaction among older adults, and their working-age counterparts.

OBJECTIVES: Stressful life events (SLEs) have been linked to depression, anxiety, and reduced life satisfaction. The inoculation hypothesis of aging suggests older adults may be less vulnerable to poor psychological outcomes following SLEs than working-age adults. The current study compared relationships between SLEs, mood and life satisfaction among older adults (65+), and adults aged 50-64, and investigated whether group identification and loneliness moderate these relationships. METHOD: A community-based sample of 121 Scottish participants responded to measures of SLEs (modified Social Readjustment Rating Scale), symptoms of depression and anxiety (Hospital Anxiety and Depression Scale), life satisfaction (Life Satisfaction Index A), group identification (Group Identification Scale), and loneliness (UCLA Loneliness Scale). RESULTS: In the 50-64 age group, the number of SLEs was significantly associated with greater symptoms of depression and anxiety, and reduced life satisfaction. Group identification and loneliness did not moderate these relationships. There were no significant relationships in the older adult group. CONCLUSION: The finding of relationships in working-age, but not older adults, supports the inoculation hypothesis of aging. Further research to better understand changes across the lifespan, and inter-relationships with related variables, would be valuable from both theoretical and clinical perspectives.

Needle size for vaccination procedures in children and adolescents.

BACKGROUND: Hypodermic needles of different sizes (gauges and lengths) can be used for vaccination procedures. The gauge (G) refers to the outside diameter of the needle tubing. The higher the gauge number, the smaller diameter of the needle (eg a 25 G needle is 0.5 mm in diameter and is narrower than a 23 G needle (0.6 mm)). Many vaccines are recommended for injection into muscle (intramuscularly), although some are delivered subcutaneously (under the skin) and intradermally (into skin). Choosing an appropriate length and gauge of a needle may be important to ensure that a vaccine is delivered to the appropriate site and produces the maximum immune response while causing the least possible harm. There are some conflicting guidelines regarding the lengths and gauges of needles that should be used for vaccination procedures in children and adolescents. OBJECTIVES: To assess the effects of using needles of different lengths and gauges for administering vaccines to children and adolescents on vaccine immunogenicity (the ability of the vaccine to elicit an immune response), procedural pain, and other reactogenicity events (adverse events following vaccine administration). SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library 2014, Issue 10), MEDLINE and MEDLINE in Progress via Ovid (1947 to November 2014), EMBASE via Ovid (1974 to November 2014), and CINAHL via EBSCOhost (1982 to November 2014). We also searched reference lists of articles and textbooks, the proceedings of vaccine conferences, and three clinical trial registers. SELECTION CRITERIA: Randomised controlled trials evaluating the effects of using hypodermic needles of any gauge or length to administer any type of vaccine to people aged from birth to 24 years. DATA COLLECTION AND ANALYSIS: Three review authors independently extracted trial data and assessed the risk of bias. We contacted trial authors for additional information. We rated the quality of evidence using the GRADE system. MAIN RESULTS: We included five trials involving 1350 participants. Data for the primary review outcomes were either absent (for the incidence of vaccine-preventable diseases) or limited (for procedural pain and crying). The available evidence was compromised by the use of surrogate immunogenicity outcomes, incomplete blinding of outcome assessors, and imprecision for some outcomes. The evidence from two small trials was insufficient to allow any confident statements to be made about the effects of the needles evaluated in the trials on vaccine immunogenicity and reactogenicity.The remaining three trials (1135 participants) contributed data to comparisons between 25 G 25 mm, 23 G 25 mm, and 25 G 16 mm needles. These trials involved infants predominantly aged two to six months undergoing intramuscular vaccination in the anterolateral thigh using the World Health Organization (WHO) injection technique (skin stretched flat, needle inserted at a 90° angle and up to the needle hub in healthy infants). The vaccines administered were combination vaccines containing diphtheria, tetanus, and whole-cell pertussis antigens (DTwP). In some trials, the vaccines also contained Haemophilus influenzae type b (DTwP-Hib) and hepatitis B (DTwP-Hib-HepB) antigen components.We found moderate quality evidence from one trial that there is probably little or no difference in immune response, defined in terms of the proportion of seroprotected infants, between using 25 G 25 mm, 23 G 25 mm, or 25 G 16 mm needles to administer a series of three doses of a DTwP-Hib vaccine at ages two, three, and four months (numbers of participants in analyses range from 309 to 402. Immune response to pertussis antigen not measured).25 mm needles (either 23 G or 25 G) probably lead to fewer severe local reactions (extensive redness and swelling) and fewer non-severe local reactions (any redness, swelling, tenderness or hardness (composite outcome)) after DTwP-Hib vaccination compared with 25 G 16 mm needles. We estimate that one fewer infant will experience a severe local reaction after the first vaccine dose for every 25 infants vaccinated with the longer rather than the shorter needle (number needed to treat (NNT) 25 (95% confidence interval (CI) 15 to 100)). We estimate that one fewer infant will experience a non-severe local reaction at 24 hours after the first, second, and third vaccine doses for every five to eight infants vaccinated with the longer rather than the shorter needle (NNTs range from 5 (95% CI 4 to 10) to 8 (95% CI 5 to 34)) (moderate quality evidence, one trial for first and second doses, two trials for third dose, numbers of participants in analyses range from 413 to 528).Using a wider gauge needle (23 G 25 mm) may slightly reduce procedural pain (low quality evidence) and probably leads to a slight reduction in the duration of crying time immediately after vaccination (moderate quality evidence) compared with a narrower gauge (25 G 25 mm) needle (one trial, 320 participants). The effects are probably not large enough to be of any clinical relevance. The 25 G 25 mm needle may produce a small reduction in the incidence of local reactions after each dose of a DTwP vaccine compared with the 23 G 25 mm needle, but the effect estimates are imprecise (low quality evidence, two trials, numbers of participants in analyses range from 100 to 459).The comparative effects of 23 G 25 mm, 25 G 25 mm, and 25 G 16 mm needles on the incidence of post-vaccination fever, persistent inconsolable crying, and other systemic events such as drowsiness, loss of appetite, and vomiting are uncertain due to the very low quality of the evidence. AUTHORS' CONCLUSIONS: Using 25 mm needles (either 23 G or 25 G) for intramuscular vaccination procedures in the anterolateral thigh of infants using the WHO injection technique probably reduces the occurrence of local reactions while achieving a comparable immune response to 25 G 16 mm needles. These findings are applicable to healthy infants aged two to six months receiving combination DTwP vaccines with a reactogenic whole-cell pertussis antigen component. These vaccines are predominantly used in developing countries. The applicability of the findings to vaccines with acellular pertussis components and other vaccines with different reactogenicity profiles is uncertain.

'Stepping in' or 'stepping back': how first year nursing students begin to learn about person-centred care.

BACKGROUND: The concept of person-centred care has gained international recognition over the last decade and forms one of the key concepts of our Nursing Quality Improvement Curricular Framework. OBJECTIVES: This study aimed to investigate nursing students' learning about person-centred care during the first-year of their programme. METHODS: Qualitative thematic analysis of a section of placement learning documents from two consecutive cohorts of students from all fields of nursing (n=405), supplemented by three focus group discussions. RESULTS: Two conceptual categories of student approaches to learning emerged. Firstly, 'stepping back', or learning from a distance about how nurses provide care, often through reading case notes and care plans; second, 'stepping in', learning about the patient as a person by direct interaction with service users. Evidence of reflection on the patient's experience of care was limited. These results have resonance with existing pedagogical theories around preferences for active or passive styles of learning. The potential for clinical mentors to build student confidence and encourage direct engagement with patients was highlighted. CONCLUSIONS: Students are aware of the concepts, principles and professional values of person-centred care from early in their programme; however, the majority tend to be preoccupied by learning about what nurses 'do', rather than 'how patients experience care'. Development towards a more person-centred approach may require targeted support from mentors to help students gain confidence and begin reflecting on how patients experience care.

Computerised cognitive behavioural therapy for depression and anxiety with older people: a pilot study to examine patient acceptability and treatment outcome.

OBJECTIVE: The study objective was to determine the acceptability and treatment outcome of using Beating the Blues (BTB) with older people (6 + years). Specific aims included identifying the treatment uptake and drop-out rate, and describing the role of basic demographics in therapy uptake. METHOD: Fifty-eight participants, experiencing symptoms of depression, were given a free choice of receiving treatment as usual (TAU) plus BTB (TAU + BTB) or TAU alone. All participants completed demographic questionnaires and a range of outcome measures at baseline, 2 months after baseline (end of treatment) and 3 months after baseline (follow-up). RESULTS: Thirty-three participants (56.9%) opted to receive BTB and reported having more experience and confidence using a computer than those who declined BTB. Twenty-four participants (72.7%) went on to complete all eight BTB sessions. Statistical analysis found significant differences between the two treatment groups, with the TAU + BTB group showing greater improvements in their symptoms of depression and anxiety than the TAU group by the end of treatment and at follow-up. Furthermore, the TAU+ BTB group had a significantly higher percentage of participants who met criteria for clinically significant improvement in their symptoms of depression by the end of treatment and at follow-up. CONCLUSION: Although further research is required, including a randomised controlled trial, the results of this initial pilot study provide evidence that BTB may offer an acceptable and effective treatment option for older people.
