Experiences of UK and Irish family carers of people with profound and multiple intellectual disabilities during the COVID-19 pandemic.

BACKGROUND: People with profound and multiple intellectual disabilities (PMID) have high and intensive support needs that ordinarily place significant strain on family carers. This was further heightened by the removal of many external supports during the COVID-19 pandemic. We sought to explore the experiences of family carers of people with PMID during the COVID-19 pandemic and understand what the longer-term impact might be on their lives. METHODS: Focus group interviews (n = 32) were conducted with family carers (n = 126) from the four countries of the UK and the Republic of Ireland. Participants were asked questions relating to their experiences of the COVID-19 pandemic, coping strategies, and challenges faced. All focus groups were conducted using the online platform, Zoom. These were audio recorded, transcribed verbatim and analysed employing inductive thematic analysis. FINDINGS: Three main themes were generated from the data including (1.0) COVID-19 as a double-edged sword (2.0), The struggle for support (3.0), Constant nature of caring. These included 11 subthemes. (1.1) 'COVID-19 as a catalyst for change', (1.2) 'Challenges during COVID-19: dealing with change', (1.3) 'Challenges during COVID-19: fear of COVID-19', (1.4); 'The online environment: the new normal' (2.1) 'Invisibility of male carers', (2.2) 'Carers supporting carers', (2.3) 'The only service you get is lip service: non-existent services', (2.4); 'Knowing your rights' (3.1) 'Emotional response to the caring role: Feeling devalued', (3.2) 'Emotional response to the caring role: Desperation of caring', (3.3) 'Multiple demands of the caring role.' CONCLUSIONS: The COVID-19 pandemic presented immense challenges to family carers of people with PMID but also provided some opportunities. Families had already struggled to receive many of the supports and services to which they were entitled to only to have these removed at the onset of the pandemic. The experiences of male carers have been largely absent from the literature with this research showing they want to be included in decision making and require tailored support services. Service providers should see the end of the COVID-19 pandemic as providing opportunity to re-examine current provision and design services with family carers. As the direct threat from COVID-19 diminishes and the experiences of those who lived through this period come to the fore, there is a need to re-examine current models and provision of support to family carers to better meet their needs.

Impact of the COVID-19 pandemic on family carers of those with profound and multiple intellectual disabilities: perspectives from UK and Irish Non-Governmental Organisations.

BACKGROUND: Family carers of people with profound and multiple intellectual disabilities (PMID) experienced a reduction in healthcare services due to the COVID-19 pandemic. Many subsequently turned to Non-Governmental Organisations who worked to support families. However, little research has sought to capture the experiences of family carers or identify effective interventions which might support them. To address these concerns we explored the views of Non-Governmental sector workers across the UK and Ireland who supported families people with PMID during the COVID-19 pandemic. We also sought to explore their views on the characteristics of online support programmes for family carers.  METHODS: This study employed a qualitative design using focus groups with participants (n = 24) from five Non-Governmental Organisations across the UK and Ireland. A focus group guide included questions on challenges, supports, coping and resources which helped during lockdown restrictions. Focus groups were held online, were audio recorded and transcribed verbatim. The resulting transcripts were pseudonymised and subjected to thematic analysis. FINDINGS: Four themes were identified (i) 'mental and emotional health', (ii) 'they who shout the loudest' (fighting for services), (iii) 'lack of trust in statutory services' and (iv) 'creating an online support programme'. Mental and emotional health emerged as the most prominent theme and included three subthemes named as 'isolation', 'fear of COVID-19' and 'the exhaustion of caring'. CONCLUSIONS: The COVID-19 pandemic has increased the vulnerability of family carers who were already experiencing difficulties in accessing services and supports for their families. While Non-Governmental Organisations have been a crucial lifeline there is urgent need to design services, including online support programmes, in partnership with family carers which adequately address their needs.

Enhanced Perinatal Programs for People in Prisons: A Summary of Six States' Programs.

Purpose: The purpose of this study was to examine enhanced perinatal support programs for pregnant and postpartum people in six state prisons, describe the service components offered by each program, and discuss similarities and differences of services offered between programs. Methods: In-depth, semi-structured interviews were conducted with each program's site lead(s) in order to collect information regarding each program's historical context, conception, and key aspects of the implementation of service components offered at each site. Results: Program components fell into five broad categories: group-based education and support, one-on-one support, labor and birth support, lactation facilitation and support, and other support services. Results highlight similarities and differences within and across programs and common themes that govern program success. Conclusions: This study provides an initial understanding of the variation in enhanced perinatal programming in six state prisons and offers insights for other states interested in establishing these types of programs. These programs implemented individual components piecemeal to fit site-specific context and needs, instead of adopting the entirety of another program model. Programs' success was largely dependent upon collaboration between program facilitators and partnering prison sites.

Changes in awareness of cancer risk factors among adult New Zealanders (CAANZ): 2001 to 2015.

Behaviour change, specifically that which decreases cancer risk, is an essential element of cancer control. Little information is available about how awareness of risk factors may be changing over time. This study describes the awareness of cancer risk behaviours among adult New Zealanders in two cross-sectional studies conducted in 2001 and 2014/5.Telephone interviews were conducted in 2001 (n = 436) and 2014/5 (n = 1064). Participants were asked to recall things they can do to reduce their risk of cancer. They were then presented with a list of potential risk behaviours and asked if these could increase or decrease cancer risk.Most New Zealand adults could identify at least one action they could take to reduce their risk of cancer. However, when asked to provide specific examples, less than a third (in the 2014/5 sample) recalled key cancer risk reduction behaviours such as adequate sun protection, physical activity, healthy weight, limiting alcohol and a diet high in fruit. There had been some promising changes since the 2001 survey, however, with significant increases in awareness that adequate sun protection, avoiding sunbeds/solaria, healthy weight, limiting red meat and alcohol, and diets high in fruit and vegetables decrease the risk of developing cancer.

A novel approach to antibiofilm susceptibility testing using a thermo-reversible matrix.

OBJECTIVE: Biofilm microorganisms are known to have a much higher tolerance to antimicrobials compared to their planktonic equivalents. Therefore, traditional antimicrobial susceptibility testing may not extrapolate to clinical treatment of infections of biofilm origin, and as a result, there is a need to not only develop antimicrobials with antibiofilm activity, but also suitable in vitro testing methods for their evaluation. In this study, we report on a novel method of antibiofilm testing using a thermo-reversible matrix (poloxamer 407), coupled with live/dead staining of bacteria cultured from the matrix. METHOD: Pseudomonas aeruginosa (NCIMB 8626) was cultured in medium containing poloxamer 407 at 37°C for 24 hours to generate biofilms. The preparation was cooled to liquefy the poloxamer and allow recovery of the biofilm cells, which were then stained with SYTO9 to determine viability following exposure to four antimicrobials: polyhexanide, octenadine dihydrochloride, povidone-iodine and silver carbonate. Over an 8-minute time period, fluorescence levels were spectrophotometrically measured and compared with bacterial controls, cultured in the absence of poloxamer and without antimicrobial. RESULTS: Untreated cells showed no reduction in viability over this period. Importantly, planktonic cells were more susceptible to test agents compared with those of a 'biofilm' phenotype cultured in poloxamer. Antibiofilm activity was evident for all of the test agents, with highest relative activity seen with octenadine dihydrochloride. CONCLUSION: In summary, a novel and relatively rapid approach to screen compounds for antibiofilm activity has been described. The method uses standard laboratory equipment and can be readily adapted to test a wide range of microorganisms and other antibiofilm compounds.

Smoke-free policies in New Zealand public tertiary education institutions.

The Framework Convention on Tobacco Control mandates the creation of smoke-free environments to protect non-smokers from second-hand smoke and reduce demand for tobacco. We aimed to examine the extent and nature of smoke-free campus policies at tertiary education institutions throughout New Zealand, and examine the policy development process. Stage one comprised an audit and content analysis of smoke-free policies. In stage two, semi-structured telephone interviews were conducted to investigate the process of developing and implementing policies. Qualitative content analysis was undertaken on interview notes. Policies were identified for most institutions (n = 26/29), though varied widely in nature. Only nine mandated 100% smoke-free campuses without exceptions and few prohibited the sale of tobacco on campus, or connections with the tobacco industry. During interviews (n = 22/29), cited barriers to developing a 100% smoke-free policy included enforcement challenges and anticipated opposition from staff and students. However, participants from institutions with 100% smoke-free policies reported having encountered few challenges. Varying levels of compliance with 100% smoke-free policies were reported yet, overall, these policies were viewed as being effective. Smoke-free campus policies could be strengthened to better reflect a completely tobacco-free organization. Other institutions and workplaces could use these findings to develop 100% smoke-free policies.

Clara cells drive eosinophil accumulation in allergic asthma.

Development of allergic asthma is a complex process involving immune, neuronal and tissue cells. In the lung, Clara cells represent a major part of the "immunomodulatory barrier" of the airway epithelium. To understand the contribution of these cells to the inflammatory outcome of asthma, disease development was assessed using an adjuvant-free ovalbumin model. Mice were sensitised with subcutaneous injections of 10 µg endotoxin-free ovalbumin in conjunction with naphthalene-induced Clara cell depletion. Clara epithelial cell depletion in the lung strongly reduced eosinophil influx, which correlated with decreased eotaxin levels and, moreover, diminished the T-helper cell type 2 inflammatory response, including interleukin (IL)-4, IL-5 and IL-13. In contrast, airway hyperresponsiveness was increased. Further investigation revealed Clara cells as the principal source of eotaxin in the lung. These findings are the first to show that Clara airway epithelial cells substantially contribute to the infiltration of eotaxin-responsive CCR3+ immune cells and augment the allergic immune response in the lung. The present study identifies Clara cells as a potential therapeutic target in inflammatory lung diseases such as allergic asthma.

Suppression of adrenomedullin contributes to vascular leakage and altered epithelial repair during asthma.

BACKGROUND: The anti-inflammatory peptide, adrenomedullin (AM), and its cognate receptor are expressed in lung tissue, but its pathophysiological significance in airway inflammation is unknown. OBJECTIVES: This study investigated whether allergen-induced airway inflammation involves an impaired local AM response. METHODS: Airway AM expression was measured in acute and chronically sensitized mice following allergen inhalation and in airway epithelial cells of asthmatic and nonasthmatic patients. The effects of AM on experimental allergen-induced airway inflammation and of AM on lung epithelial repair in vitro were investigated. RESULTS: Adrenomedullin mRNA levels were significantly (P < 0.05) reduced in acute ovalbumin (OVA)-sensitized mice after OVA challenge, by over 60% at 24 h and for up to 6 days. Similarly, reduced AM expression was observed in two models of chronic allergen-induced inflammation, OVA- and house dust mite-sensitized mice. The reduced AM expression was restricted to airway epithelial and endothelial cells, while AM expression in alveolar macrophages was unaltered. Intranasal AM completely attenuated the OVA-induced airway hyperresponsiveness and mucosal plasma leakage but had no effect on inflammatory cells or cytokines. The effects of inhaled AM were reversed by pre-inhalation of the putative AM receptor antagonist, AM ((22-52)) . AM mRNA levels were significantly (P < 0.05) lower in human asthmatic airway epithelial samples than in nonasthmatic controls. In vitro, AM dose-dependently (10(-11) -10(-7) M) accelerated experimental wound healing in human and mouse lung epithelial cell monolayers and stimulated epithelial cell migration. CONCLUSION: Adrenomedullin suppression in T(H) 2-related inflammation is of pathophysiological significance and represents loss of a factor that maintains tissue integrity during inflammation.

Is It Time to Create Training Pathways Allowing Earlier Subspecialization within the "House of Orthopaedics"?: AOA Critical Issues.

ABSTRACT: The ability to train an orthopaedic resident in all aspects of orthopaedics in 5 years has become increasingly difficult due to the growth in knowledge and techniques, work-hour restrictions, and reduced resident autonomy. It has become nearly universal for our residents to complete at least 1 subspecialty fellowship prior to entering practice. In some subspecialties, the skills necessary to practice competently have become difficult to master. Simply adding to the current length of training may not address these issues effectively and would add to the economic cost of residency training. Novel training pathways that allow residents to focus earlier and in greater depth on their intended subspecialty while maintaining general orthopaedic competencies can be created without lengthening training. It is time to initiate discussions about these possibilities.

Clinical vignettes in Parkinson's disease: a collection of unusual medication-induced hallucinations, delusions, and compulsive behaviours.

Hallucinations, delusions, and compulsive behaviors are frequent iatrogenic complications of the treatment of motor dysfunction in Parkinson's disease (PD). Although these have been studied, and the phenomenology described, there are few detailed descriptions of the various psychiatric problems our treated PD patients live with that allow physicians who do not have a great deal of experience with PD patients to appreciate the extent of their altered lives. This report is a compilation of vignettes describing these behavioral problems that the treating neurologist or psychiatrist attributed to the medications used for treating PD.

Long-term cognitive and psychiatric outcomes of acute respiratory distress syndrome managed with Extracorporeal Membrane Oxygenation.

BACKGROUND: Cognitive dysfunction is often reported in patients who have experienced acute respiratory distress syndrome (ARDS). Extra Corporeal Membrane Oxygenation (ECMO) therapy is increasingly used to manage ARDS patients in ICU, transforming survival rates. However, few studies have examined cognitive outcomes. METHODS: We examined self-reported cognitive complaints, psychiatric outcomes and neuropsychological test performance in survivors of severe hypoxaemia managed with VV-ECMO, at 18-24 month follow-up, compared with a group of healthy controls. RESULTS: Over 70% of ECMO-treated patients (N = 46) complained of difficulty in at least one aspect of cognition on self-report measures (study 1). However, a much lower frequency of cognitive impairment was found on formal neuropsychological testing (study 2). Mean neuropsychological test scores of the ECMO group (N = 24) did not significantly differ from healthy controls (N = 23) after controlling for depression. Less than 30% of ECMO-treated patients showed impairments in anterograde memory, and deficits on general IQ or executive function were seen in <17% of patients. However, we observed high levels of self-reported anxiety and depression in the ECMO-treated patients. CONCLUSIONS: Cognitive outcomes in ECMO-treated patients were generally good, with preserved neuropsychological function in the majority of patients, despite severe hypoxaemia and high rates of self-reported difficulties. However, we saw high levels of mental health symptoms in these patients, highlighting a need for psychological support.

Treatment of metastatic placental site trophoblastic tumor with surgery, chemotherapy, immunotherapy and coil embolization of multiple pulmonary arteriovenous fistulate.

Placental Site Trophoblastic Tumor (PSTT) is a rare malignancy that often presents with extensive disease and can be resistant to traditional treatments. We present the case of a woman with stage IV PSTT who was initially managed with neoadjuvant chemotherapy followed by tumor debulking. Adjuvant therapy was guided by further pathologic analysis that revealed high levels of staining for PD-L1 as well as the presence of tumor infiltrating lymphocytes (TILs). Subsequently, the patient was treated with traditional chemotherapy with the EP/EMA regimen with the addition of pembrolizumab. The patient's treatment course was complicated by the development of pulmonary arteriovenous malformations, autoimmune thyroiditis thought to be secondary to immunotherapy, and significant tinnitus secondary to platinum agents. Currently the patient is in follow up and remains in a complete remission.

Role of the ABC transporter Ste6 in cell fusion during yeast conjugation.

Though early stages of yeast conjugation are well-mimicked by treatment with pheromones, the final degradation of the cell wall and membrane fusion of mating that leads to cytoplasmic mixing may require separate signals. Mutations that blocked cell fusion during mating in Saccharomyces cerevisiae were identified in a multipartite screen. The three tightest mutations proved to be partial-function alleles of the ABC-transporter gene STE6 required for transport of a-factor. The ste6(cefl-1) allele was recovered and sequenced. The ste6(cefl-1) allele contained a stop codon predicted to truncate Ste6 at amino acid residue 862 (of 1290). The ste6(cef) mutations reduced, but did not eliminate, expression of a-factor. Light and electron microscopy revealed that unlike ste6 null mutations which block mating before the formation of mating pairs, the ste6(cef) (cell fusion) alleles permitted early steps in mating to proceed normally but blocked at a late stage in conjugation where mating partners were encased by a single cell wall and separated by only a thin layer of cell wall material we term the fusion wall. Morphologically the prezygotes appeared symmetrical with successful cell wall fusion at the periphery of the region of cell contact. Responses to a-factor were efficiently induced in partner cells under mating conditions as expected given the symmetric appearance of the prezygotes. A strain expressing a ste6(K1093A) mutation that conferred export of a twofold to fourfold higher level of a-factor than ste6(cef) did not accumulate prezygotes during mating which could indicate a tight threshold of a-factor signaling required for mating. However, mating to an sst2 partner which has a greatly increased sensitivity to a-factor did not suppress the fusion defect of a ste6(cef) strain. Overexpression of the structural gene for a-factor also did not suppress the fusion defect. It is possible that a-factor or STE6 play more complex roles in cell fusion.

Growth of neurites without filopodial or lamellipodial activity in the presence of cytochalasin B.

To examine the role in neurite growth of actin-mediated tensions within growth cones, we cultured chick embryo dorsal root ganglion cells on various substrata in the presence of cytochalasin B. Time-lapse video recording was used to monitor behaviors of living cells, and cytoskeletal arrangements in neurites were assessed via immunofluorescence and electron microscopic observations of thin sections and whole, detergent-extracted cells decorated with the S1 fragment of myosin. On highly adhesive substrata, nerve cells were observed to extend numerous (though peculiarly oriented) neurites in the presence of cytochalasin, despite their lack of both filopodia and lamellipodia or the orderly actin networks characteristic of typical growth cones. We concluded that growth cone activity is not necessary for neurite elongation, although actin arrays seem important in mediating characteristics of substratum selectivity and neurite shape.

A role for a protease in morphogenic responses during yeast cell fusion.

Cell fusion during yeast mating provides a model for signaling-controlled changes at the cell surface. We identified the AXL1 gene in a screen for genes required for cell fusion in both mating types during mating. AXL1 is a pheromone-inducible gene required for axial bud site selection in haploid yeast and for proteolytic maturation of a-factor. Two other bud site selection genes, RSR1, encoding a small GTPase, and BUD3, were also required for efficient cell fusion. Based on double mutant analysis, AXL1 in a MATalpha strain acted genetically in the same pathway with FUS2, a fusion-dedicated gene. Electron microscopy of axl1, rsr1, and fus2 prezygotes revealed similar defects in nuclear migration, vesicle accumulation, cell wall degradation, and membrane fusion during cell fusion. The axl1 and rsr1 mutants exhibited defects in pheromone-induced morphogenesis. AXL1 protease function was required in MATalpha strains for fusion during mating. The ability of the Rsr1p GTPase to cycle was required for efficient cell fusion, as it is for bud site selection. During conjugation, vegetative functions may be redeployed under the control of pheromone signaling for mating purposes. Since Rsr1p has been reported to physically associate with Cdc24p and Bem1p components of the pheromone response pathway, we suggest that the bud site selection genes Rsr1p and Axl1p may act to mediate pheromone control of Fus2p-based fusion events during mating.

A mechanism for nuclear positioning in fission yeast based on microtubule pushing.

The correct positioning of the nucleus is often important in defining the spatial organization of the cell, for example, in determining the cell division plane. In interphase Schizosaccharomyces pombe cells, the nucleus is positioned in the middle of the cylindrical cell in an active microtubule (MT)-dependent process. Here, we used green fluorescent protein markers to examine the dynamics of MTs, spindle pole body, and the nuclear envelope in living cells. We find that interphase MTs are organized in three to four antiparallel MT bundles arranged along the long axis of the cell, with MT plus ends facing both the cell tips and minus ends near the middle of the cell. The MT bundles are organized from medial MT-organizing centers that may function as nuclear attachment sites. When MTs grow to the cell tips, they exert transient forces produced by plus end MT polymerization that push the nucleus. After an average of 1.5 min of growth at the cell tip, MT plus ends exhibit catastrophe and shrink back to the nuclear region before growing back to the cell tip. Computer modeling suggests that a balance of these pushing MT forces can provide a mechanism to position the nucleus at the middle of the cell.

Positivity bias in past and future episodic thinking: Relationship with anxiety, depression, and retrieval-induced forgetting.

Positivity biases in autobiographical memory and episodic future thinking are considered important in mental wellbeing and are reduced in anxiety and depression. The inhibitory processes underlying retrieval-induced forgetting (RIF) have been proposed to contribute to these biases. This investigation found reduced positivity in past and future thinking to be associated with reduced memory specificity alongside greater levels of anxiety, depression, and rumination. Most notably, however, RIF was found to significantly predict memory valence. This indicates that RIF may be important in maintaining such biases, facilitating the forgetting of negative memories when a positive item is actively retrieved.

Transcription factor Fra-2 and its emerging role in matrix deposition, proliferation and inflammation in chronic lung diseases.

Fos-related antigen-2 (Fra-2) belongs to the activator protein 1 (AP-1) family of transcription factors and is involved in a broad variety of cellular processes, such as proliferation or differentiation. Aberrant expression of Fra-2 or regulation can lead to severe growth defects or diverse pathologies. Elevated Fra-2 expression has been described in several chronic lung diseases, such as pulmonary fibrosis, chronic obstructive pulmonary disease and asthma. However, the pathomechanisms behind the Fra-2-induced pulmonary remodelling are still not fully elucidated. Fra-2 overexpressing mice were initially described as a model of systemic sclerosis associated organ fibrosis, with predominant alterations in the lung. High levels of Fra-2 expression give rise to profound inflammation with severe remodelling of the parenchyma and the vasculature, resulting in fibrosis and pulmonary hypertension, respectively, but also alters bronchial function. In this review we discuss the central role of Fra-2 connecting inflammation, cellular proliferation and extracellular matrix deposition underlying chronic lung diseases and what we can learn for future therapeutic options.

Intimate partner violence among HIV-positive women in Nairobi, Kenya.

PURPOSE: This study was conducted to identify the prevalence and sociodemographic factors associated with four forms of intimate partner violence (IPV) among HIV-positive women attending the Comprehensive Care Centre at the Kenyatta National Hospital in Nairobi, Kenya. METHODS: A cross-sectional study was conducted among 600 sexually active HIV-positive women aged 18-69 years from May to August of 2012. A structured questionnaire including questions pertaining to sociodemographic characteristics, health care decisions, and forms of IPV (controlling behavior, emotional abuse, physical violence, and sexual violence) was administered to each woman. RESULTS: All women reported experiencing emotional abuse; 20%, 17%, and 15% experienced controlling behavior, physical violence, and sexual violence, respectively. Women who reported low/below average socioeconomic status (SES) had a greater likelihood of experiencing controlling behavior than women with high/average SES (adjusted odds ratio [aOR] =1.62, 95% CI 1.05-2.51). Women who were unemployed had greater odds of experiencing physical violence than those who were employed (aOR =2.35, 95% CI 1.31-4.23). Non-Christian women had higher odds of experiencing controlling behavior, physical violence, and sexual violence than Christian women (aOR =4.41, 95% CI 1.81-10.76 and aOR =3.33, 95% CI 1.43-7.80). CONCLUSION: Based on the prevalence of IPV and the sociodemographic factors identified to be associated with IPV among women in this study it may be beneficial to include IPV screening as part of routine clinic visits for HIV-positive and other women. Furthermore, women who report emotional abuse or controlling behavior from spouse should not be overlooked, as these two forms of IPV may precede or accompany physical and sexual IPV. Women who report experiencing IPV during clinic visits may be referred to organizations and resources available to battered women in Kenya. Increased funding for anti-IPV programs and changes in policy may also contribute to a reduction in IPV among HIV-positive and other women in Kenya.
