Primary care practice-based interventions and their effect on participation in population-based cancer screening programs: a systematic narrative review.

AIM: To provide a systematic synthesis of primary care practice-based interventions and their effect on participation in population-based cancer screening programs. BACKGROUND: Globally, population-based cancer screening programs (bowel, breast, and cervical) have sub-optimal participation rates. Primary healthcare workers (PHCWs) have an important role in facilitating a patient's decision to screen; however, barriers exist to their engagement. It remains unclear how to best optimize the role of PHCWs to increase screening participation. METHODS: A comprehensive search was conducted from January 2010 until November 2023 in the following databases: Medline (OVID), EMBASE, and CINAHL. Data extraction, quality assessment, and synthesis were conducted. Studies were separated by whether they assessed the effect of a single-component or multi-component intervention and study type. FINDINGS: Forty-nine studies were identified, of which 36 originated from the USA. Fifteen studies were investigations of single-component interventions, and 34 studies were of multi-component interventions. Interventions with a positive effect on screening participation were predominantly multi-component, and most included combinations of audit and feedback, provider reminders, practice-facilitated assessment and improvement, and patient education across all screening programs. Regarding bowel screening, provision of screening kits at point-of-care was an effective strategy to increase participation. Taking a 'whole-of-practice approach' and identifying a 'practice champion' were found to be contextual factors of effective interventions.The findings suggest that complex interventions comprised of practitioner-focused and patient-focused components are required to increase cancer screening participation in primary care settings. This study provides novel understanding as to what components and contextual factors should be included in primary care practice-based interventions.

Lived experiences of women during induction of labour at a tertiary hospital in Ghana: A qualitative study.

Induction of labour (IOL) has become a major and vital maternal health intervention to facilitate childbirth and minimize the rising caesarean section rates globally. However, there is limited information to facilitate appropriate client counselling, birth preparedness and informed decision making although the procedure has inherent tendency for adverse maternal/perinatal outcomes. Given the need for optimal client education and shared decision making in maternal health, this study explored women's knowledge and their lived experiences of IOL. This qualitative study used in-depth interviews, conducted at the largest teaching hospital in Ghana. Purposive sampling was used to recruit the study participants. Data analysis was performed based on thematic content using inductive framework synthesis. We included 17 women who had undergone IOL, delivered and discharged. Most participants(52.9%) were ≥30 years old, married(88.2%), and 41.1% had no previous childbirth experience. The main indications of IOL were postdate(47%), pre-eclampsia(29%) and gestational diabetes mellitus(11.8%). Data synthesis resulted in three broad themes: women's knowledge on IOL, women's experiences of care and women's difficult experiences including coping mechanisms. We determined mixed responses concerning the themes explored: adequate versus inadequate knowledge; positive versus negative experiences of care and satisfaction. Nearly all women mentioned vaginal examination as their most difficult experience due to severe pain, extreme discomfort, and being psychologically traumatic. The main coping strategy the women developed to navigate the traumatic vaginal examination was by "psyching" themselves. Our study indicates women encounter significant negative and positive experiences during IOL and childbirth in Ghana with vaginal examination cited as the most painful experience. Appropriate antenatal counselling, women empowerment and pre-labour education on childbirth processes and expectations are recommended to enhance birth preparedness and complication awareness. Health system improvement and regular refreshers courses for health workers are urgently required to promote positive women's experiences of care during labour induction and childbirth.

68Ga-DOTATATE: Significance of Uptake in the Tail of the Pancreas in Patients Without Lesions.

PURPOSE: To measure the SUVs in the tail of the pancreas compared with normal liver parenchyma and somatostatin receptor-positive lesions. MATERIALS AND METHODS: Ga-DOTATATE PET/low mAs CT of 35 patients were reviewed. RESULTS: There was no significant difference (P = 0.59) between the SUVaverage of normal liver and the SUVpeak of normal tail. Five patients had uptake in the tail slightly above that of normal liver that were interpreted equivocally. In one of these patients with Ga-DOTATATE uptake in a peripancreatic lymph node, proven neuroendocrine tumor underwent a distal pancreatectomy and pathologic examination revealed islet cell hyperplasia. CONCLUSIONS: Ga-DOTATATE uptake in the tail of the pancreas above that of normal liver indicates a somatostatin receptor-avid lesion. Uptake in the tail of the pancreas equal to the liver can be normal. Patients with uptake equivalent to the liver should undergo further anatomical imaging before procedural intervention.

Cross-species conservation of complementary amino acid-ribonucleobase interactions and their potential for ribosome-free encoding.

The role of amino acid-RNA nucleobase interactions in the evolution of RNA translation and protein-mRNA autoregulation remains an open area of research. We describe the inference of pairwise amino acid-RNA nucleobase interaction preferences using structural data from known RNA-protein complexes. We observed significant matching between an amino acid's nucleobase affinity and corresponding codon content in both the standard genetic code and mitochondrial variants. Furthermore, we showed that knowledge of nucleobase preferences allows statistically significant prediction of protein primary sequence from mRNA using purely physiochemical information. Interestingly, ribosomal primary sequences were more accurately predicted than non-ribosomal sequences, suggesting a potential role for direct amino acid-nucleobase interactions in the genesis of amino acid-based ribosomal components. Finally, we observed matching between amino acid-nucleobase affinities and corresponding mRNA sequences in 35 evolutionarily diverse proteomes. We believe these results have important implications for the study of the evolutionary origins of the genetic code and protein-mRNA cross-regulation.
