Several studies point to the importance of peptides and proteolysis in Alzheimer's disease (AD). Because of its ability to study small proteins and peptides, reverse-phase HPLC was employed to study these species in AD. Cerebellum was chosen for these initial studies because it does not show significant neuronal loss but does show some pathology in AD. Examination of over 600 peptide peaks per case revealed 15 that were elevated in AD. Nine were fragments of hemoglobin, and the remainder included two species of calmodulin, two of myelin basic protein, and one each of 67 kDa neurofilament protein and PEP-19. The cleavage sites on hemoglobin were after hydrophobic residues and immunolocalization was seen preferentially around blood vessel walls and granule cells. The elevation of the non-serum-derived peptides was characteristic of general metabolic changes that occurred in AD cerebellum, and the presence of elevated hemoglobin polypeptides indicated either possible disruption of the blood-brain barrier or selective evasion of it by peptidaceous products. Further studies are required to establish whether hemoglobin fragments have a role in neurodegenerative processes such as AD.

Background As older patients’ health care needs become more complex, they often experience challenges with managing medications across transitions of care. Families play a major role in older patients’ lives. To date, there has been no review of the role of families in older people’s medication management at transitions of care. This systematic review aimed to examine family involvement in managing older patients’ medications across transitions of care. Methods Five databases were searched for quantitative, qualitative and mixed methods empirical studies involving families of patients aged 65 years and older: Cumulative Index to Nursing and Allied Health Literature Complete, Medline, the Cochrane Central Register of Controlled Trials, PsycINFO, and EMBASE. All authors participated independently in conducting data selection, extraction and quality assessment using the Mixed Methods Appraisal Tool. A descriptive synthesis and thematic analysis were undertaken of included papers. Results Twenty-three papers were included, comprising 17 qualitative studies, 5 quantitative studies and one mixed methods study. Families participated in information giving and receiving, decision making, managing medication complexity, and supportive interventions in regard to managing medications for older patients across transitions of care. However, health professionals tended not to acknowledge the medication activities performed by families. While families actively engaged with older patients in strategies to ensure safe medication management, communication about medication plans of care across transitions tended to be haphazard and disorganised, and there was a lack of shared decision making between families and health professionals. In managing medication complexity across transitions of care, family members perceived a lack of tailoring of medication plans for patients’ needs, and believed they had to display perseverance to have their views heard by health professionals. Conclusions Greater efforts are needed by health professionals in strengthening involvement of families in medication management at transitions of care, through designated family meetings, clinical bedside handovers, ward rounds, and admission and discharge consultations. Future work is needed on evaluating targeted strategies relating to family members’ contribution to managing medications at transitions of care, with outcomes directed on family understanding of medication changes and their input in preventing and identifying medication-related problems.

The Newcastle Asthma Knowledge questionnaire was used to determine primary schoolteachers' knowledge of asthma. The mean score achieved (20.71 +/- 3.20), was representative of a reasonable degree of knowledge. However, knowledge of symptoms associated with asthma and of medications used to manage the condition was poor. Teachers who had contact with an asthmatic individual or who had received previous training on asthma had a significantly greater knowledge of asthma. An asthma training session, delivered by a pharmacist, was found to significantly improve primary schoolteachers' knowledge of the condition, however, the extent of the improvement was low.

In analyses of 2 large independent cohorts in the United Kingdom, low-dose aspirin usage was not associated with increased survival of patients diagnosed with esophageal or gastric cancer.

COVID-19 has changed life beyond recognition for millions of individuals, as countries implement social distancing measures to prevent disease transmission. For certain patient groups, such as community-dwelling older people with dementia (PwD), these restrictions may have far-reaching consequences. Medicines management may be adversely affected and deserves careful thought. PwD face unique challenges with medicines management compared to other older people, often relying upon support from family/carers and primary healthcare professionals. This article considers potential issues that PwD may face with each component of medicines management (prescribing, dispensing, administration, adherence, review), and based on previous research, highlights strategies to support PwD and their carers during this time. Primary healthcare professionals must be attentive to medicines-related needs of community-dwelling PwD, particularly those living alone, both during the pandemic and as restrictions are lifted. Carers of PwD continue to have a critical role to play in medicines management, and also require support.
