Promoting food literacy in type 2 diabetes: a systematic review

Background

Diabetes is one of the major global health threats whose burden is sharply increasing. Food literacy is proved to be relevant to optimize self-management in diabetic patients. The present review aims to map the current literature on educational interventions to promote food literacy in type 2 diabetes, with a particular focus on the concept of patient engagement.

Methods

Five databases were queried using the Population-Intervention-Context-Outcome (PICO) model. Individual study quality was assessed using the Quality Criteria Checklist for primary research provided by the American Diabetes Association. Data were summarized using descriptive statistic and a comparison between intervention carried out by a multidisciplinary team versus a single professionist was performed adopting a Chi-square test (p < 0.05 was deemed as statistically significant).

Results

Of 1580 articles, 28 were finally included. Outcome categories were narratively labelled as “clinical”, “psychological”, “behavioural” and “literacy”. When the provider was a multidisciplinary team (25% of studies) improvement in self-management occurred in 86% of cases while in single-provider intervention the percentage was 71%, but the difference was not significant (p = 0.45). In the 10.7% of articles the use of technologies was reported, but generically descripted as the use of webpages, email or social media. Globally, an improvement in food literacy was reported in 75% of the interventions.

Conclusions

Nowadays, the use of a technology proxy is recognized as an efficient support in boosting patients' education, but the evidence in improving food literacy is scarce and difficult to compare. Public health programs improving food literacy are effective at different levels. These findings should encourage decision makers to allocate resources in this kind of programs.

Key messages

Engaging people in the management of their disease by increasing food literacy level may represent a first step to reach the “health in all policies” approach. When planning a public health intervention, allocating resources for improving individual’s education is essential to achieve better health outcomes.

Educational Interventions for Promoting Food Literacy and Patient Engagement in Preventing Complications of Type 2 Diabetes: A Systematic Review

The present review aims to map the current literature on educational interventions to promote food literacy in type 2 diabetes, with a particular focus on the concept of patient engagement. The systematic review was implemented on five databases with no restrictions on the publication year. The studies selected for the review were focused on patients with type 2 diabetes, ranging from 2003 to 2021 and published in 13 countries (44% USA). Thirty-three articles were analyzed. Twenty-seven articles targeted singular patients; fifteen articles conceptualized patient engagement as self-management. In seven articles, the provider is a multidisciplinary team. Twenty articles did not report a theoretical framework in the intervention development, and eleven did not use an intervention material. Twenty-six articles did not use a technology proxy. Outcome categories were narratively mapped into four areas: clinical, psychological, behavioral, and literacy. To date, most of the interventions are heterogeneous in the adopted methodology, measures, and outcomes considered. More attention should be given to the psychosocial characterization of patient engagement as well as the technological support. High-quality, randomized controlled trials and longitudinal studies are lacking and need to be conducted to verify the efficacy of these insights.

Patient health engagement model: explaining citizens noncompliance and maladaptive behaviors

Background

At the end of February 2020 a new case was diagnosed with COVID-19 in north Italy, suddenly followed by new cases. Italian health authorities decided to enforce restrictive measures. Northern areas of Italy were identified as “red areas” to slow down the epidemic and its impact on the healthcare system. From this perspective, the COVID-19 epidemic in Italy constitutes a testing ground for the assessment of the ability of consumers to cope with this health risk.

Methods

A cross-sectional study on a representative sample of 1000 Italian citizens was conducted over the period 27 February- 5 March exploring the following hypotheses: 1) less engaged individuals are more concerned for the health emergency and feel more vulnerable; 2) less engaged have higher probability to develop negative attitudes and dysfunctional behaviors.

Results

only the 16% the interviewees presented a high level of engagement. Lower levels of engagement were measured in the southern parts of Italy (not yet touched by the epidemics at the time of data collection). People with lowers levels of engagement reported higher fears for the contagion and sense of vulnerability. Furthermore, they showed the lower levels of trust in the Public Health Authorities, in medical research and in vaccines. Finally, they appeared more dismissive in their preventive behaviors and more disorganized in the fruition of the healthcare services.

Conclusions

A psychological analysis of processes of attitudinal and role change in the direction of becoming more engaged in health prevention is worthy in order to forecast potential dysfunctional reactions to restrictive health prevention measures and to orient personalized education initiatives to consumers with different level of engagement.

Key messages

Profiling based on the levels of health engagement is important in order to plan more effective healthcare measures during epidemics.

Targeted educational initiatives should take into account citizens' engagement profiles.

Diagnostic anoctamin-5 protein defect in patients with ANO5-mutated muscular dystrophy

AIMS

Previously, detection of ANO5 protein has been complicated by unspecific antibodies, most of which have not identified the correct protein. The aims of the study were to specify ANO5 protein expression in human skeletal muscle, and to investigate if the ANO5 protein levels are affected by different ANO5 mutations in anoctaminopathy patients.

METHODS

Four different antibodies were tested for ANO5 specificity. A sample preparation method compatible with membrane proteins, combined with tissue fractionation was used to determine ANO5 expression in cell cultures expressing ANO5, in normal muscles and eight patient biopsies with six different ANO5 mutations in homozygous or compound heterozygous states, and in other dystrophies.

RESULTS

Only one specific monoclonal N-terminal ANO5 antibody was efficient in detecting the protein, showing that ANO5 is expressed as a single 107 kD polypeptide in human skeletal muscle. The truncating mutations c.191dupA and c.1261C>T were found to abolish ANO5 expression, whereas the studied point mutations had variable effects; however, all the ANO5 mutations resulted in clearly reduced ANO5 expression in the patient muscle membrane fraction. Attempts to detect ANO5 using immunohistochemistry were not yet successful.

CONCLUSIONS

The data presented here indicate that the ANO5 protein expression is decreased in ANO5-mutated muscular dystrophy and that most of the non-truncating pathogenic ANO5 mutations likely destabilize the protein and cause its degradation. The method described here allows direct analysis of human ANO5 protein, which can be used in diagnostics, for evaluating the pathogenicity of the potentially harmful ANO5 variants of uncertain significance.

Association study reveals novel risk loci for sporadic inclusion body myositis

BACKGROUND AND PURPOSE

The aim was to identify potential genetic risk factors associated with sporadic inclusion body myositis (sIBM).

METHODS

An association based case-control approach was utilized on whole exome sequencing data of 30 Finnish sIBM patients and a control cohort (n = 193). A separate Italian cohort of sIBM patients (n = 12) was used for evaluation of the results.

RESULTS

Seven single nucleotide polymorphisms were identified in five genes that have a considerably higher observed frequency in Finnish sIBM patients compared to the control population, and the previous association of the genetic human leukocyte antigen region was confirmed.

CONCLUSIONS

All seven identified variants could individually or in combination increase the susceptibility for sIBM.

Partnering dispersion corrections with modern parameter-free double-hybrid density functionals

The PBE-QIDH and SOS1-PBE-QIDH double-hybrid density functionals are merged with a pair of dispersion corrections, namely the pairwise additive D3(BJ) and the non-local correlation functional VV10, leading to the corresponding dispersion-corrected models.

MYH7-related myopathies: clinical, histopathological and imaging findings in a cohort of Italian patients

BACKGROUND

Myosin heavy chain 7 (MYH7)-related myopathies are emerging as an important group of muscle diseases of childhood and adulthood, with variable clinical and histopathological expression depending on the type and location of the mutation. Mutations in the head and neck domains are a well-established cause of hypertrophic cardiomyopathy whereas mutation in the distal regions have been associated with a range of skeletal myopathies with or without cardiac involvement, including Laing distal myopathy and Myosin storage myopathy. Recently the spectrum of clinical phenotypes associated with mutations in MYH7 has increased, blurring this scheme and adding further phenotypes to the list. A broader disease spectrum could lead to misdiagnosis of different congenital myopathies, neurogenic atrophy and other neuromuscular conditions.

RESULTS

As a result of a multicenter Italian study we collected clinical, histopathological and imaging data from a population of 21 cases from 15 families, carrying reported or novel mutations in MYH7. Patients displayed a variable phenotype including atypical pictures, as dropped head and bent spine, which cannot be classified in previously described groups. Half of the patients showed congenital or early infantile weakness with predominant distal weakness. Conversely, patients with later onset present prevalent proximal weakness. Seven patients were also affected by cardiomyopathy mostly in the form of non-compacted left ventricle. Muscle biopsy was consistent with minicores myopathy in numerous cases. Muscle MRI was meaningful in delineating a shared pattern of selective involvement of tibialis anterior muscles, with relative sparing of quadriceps.

CONCLUSION

This work adds to the genotype-phenotype correlation of MYH7-relatedmyopathies confirming the complexity of the disorder.

Psychiatric comorbidity and psychosocial stress in patients with tension-type headache from headache centers in Italy. The Italian Collaborative Group for the Study of Psychopathological Factors in Primary Headaches

A multicenter study was carried out in 10 Italian Headache Centers to investigate the prevalence of psychosocial stress and psychiatric disorders listed by the IHS classification as the "most likely causative factors" of tension-type headache (TTH). Two hundred and seventeen TTH adult outpatients consecutively recruited underwent a structured psychiatric interview (CIDI-c). The assessment of psychosocial stress events was carried out using an ad hoc questionnaire. The psychiatric disorders that we included in the three psychiatric items of the fourth digit of the IHS classification were depressive disorders for the item depression, anxiety disorders for the item anxiety, and somatoform disorders for the item headache as a delusion or an idea. Diagnoses were made according to DSM-III-R criteria. At least one psychosocial stress event or a psychiatric disorder was detected in 84.8% of the patients. Prevalence of psychiatric comorbidity was 52.5% for anxiety, 36.4% for depression, and 21.7% for headache as a delusion or an idea. Psychosocial stress was found in 29.5% of the patients and did not differ between patients with and without psychiatric comorbidity. Generalized anxiety disorder (83.3%) and dysthymia (45.6%) were the most frequent disorders within their respective psychiatric group. The high prevalence of psychiatric disorders observed in this wide sample of patients emphasizes the need for a systematic investigation of psychiatric comorbidity aimed at a more comprehensive and appropriate clinical management of TTH patients.

Stress, mood disorders and memory in headache

Comorbidity between headache and other disorders such as psychological or memory problems is a topic of increasing scientific interest both for us diagnostic and therapeutic implications but also for pathogenetic advances. A central neurogenic mechanism such as a dysregulation of some neurotransmitter system might underlie not only headache but also other coexistent disorders; findings highlight the role of serotonin pathways.

Quality of life in shift work syndrome

Air Force radar controllers represent an excellent example of night shift workers, as they are obliged to demonstrate perfect alertness during working hours. We set out: a) to assess the quality of life in these shift workers; b) to identify those with shift work syndrome and c) to evaluate the possible effects of triazolam both on their quality of life and sleep. The results reveal an impairment of the quality of life in shift workers, independently of the presence of a circadian rhythm sleep disorder. Quality of life was more severely impaired in subjects with circadian rhythm sleep disorder. Hypnotic therapy brought about an improvement both in the sleep disorder and in the quality of life of subjects affected by shift work syndrome. Selective alertness tests failed to demonstrate any "sedative carry-over" in the treated patients.

EEG features in juvenile migraine: topographic analysis of spontaneous and visual evoked brain electrical activity: a comparison with adult migraine

Topographic analysis of spontaneous and steady-state visual evoked brain electrical activity was carried out between attacks in 82 migraine patients (40 youths and 42 adults). In adult migraine with aura a significant increase of delta rhythm percentage power was observed compared with migraine without aura and age-matched controls. Children suffering from migraine both with aura and without aura had an increased theta rhythm compared to normal controls. The presence of alpha interhemispheric asymmetry discriminated between migraine with aura and without aura, just as in adults. An increased amplitude of the SVEP F1 component with a tendency to the spread of visual reactivity was observed in juvenile migraine with and without aura; this pattern was not dissimilar from the one previously observed in adult migraine with and without aura. Abnormal photic driving in migraine is independent of age and type of migraine.

[Sleep in a case of hemiballism]

Sleep spindles abnormalities in extrapyramidal disorders have already been reported, but in the unilateral syndromes the data are unclear and inconclusive. In the attempt to clarify the problem we describe nocturnal sleep in a patient with hemiballism due to an ischemic damage of the subthalamic nucleus. The patient improved after one month haloperidol therapy and her unilateral (right) hyperkinesias disappeared. Electropolygraphic records (EEG, EOG, EMG of chin muscles, ECG) during spontaneous nocturnal sleep were obtained before therapy and after one month haloperidol treatment. The EEGs from bilateral fronto-central derivations were also recorded on magnetic tape to allow spectral analysis and automatic spindle detection by means of digital filtering. The pattern of spindle appearance rate for each stage 2 and 3 NonREM sleep in each night was investigated. We obtained: spindling index, that is the ratio between total spindle duration and sleep stage length, the mean number of spindle bursts/min, the average duration of sleep spindles, the mean amplitude, the mean time between spindles. Before therapy polygraphic records showed short total sleep time, a prolonged sleep latency, the lack of slow waves sleep and of REM sleep. After haloperidol treatment these parameters improved: total sleep time was longer, sleep latency shorter, slow waves sleep and REM sleep appeared. Before treatment spindle activity predominated in the left hemisphere - homolaterally to the subthalamic nucleus damage -, where the spindling index was higher, the mean number of spindle bursts/min larger, the mean time between spindles lower. After therapy, when hemisomatic hyperkinesias disappeared, spindle activity turned similar in the two hemispheres, since it decreased in the left hemisphere and it was unchanged in the right one.(ABSTRACT TRUNCATED AT 250 WORDS)
