Spatial, temporal, and demographic patterns in prevalence of chewing tobacco use in 204 countries and territories, 1990-2019: a systematic analysis from the Global Burden of Disease Study 2019

Abstract: Summary Background Chewing tobacco and other types of smokeless tobacco use have had less attention from the global health community than smoked tobacco use. However, the practice is popular in many parts of the world and has been linked to several adverse health outcomes. Understanding trends in prevalence with age, over time, and by location and sex is important for policy setting and in relation to monitoring and assessing commitment to the WHO Framework Convention on Tobacco Control. Methods We estimated prevalence of chewing tobacco use as part of the Global Burden of Diseases, Injuries, and Risk Factors Study 2019 using a modelling strategy that used information on multiple types of smokeless tobacco products. We generated a time series of prevalence of chewing tobacco use among individuals aged 15 years and older from 1990 to 2019 in 204 countries and territories, including age-sex specific estimates. We also compared these trends to those of smoked tobacco over the same time period. Findings In 2019, 273·9 million (95% uncertainty interval 258·5 to 290·9) people aged 15 years and older used chewing tobacco, and the global age-standardised prevalence of chewing tobacco use was 4·72% (4·46 to 5·01). 228·2 million (213·6 to 244·7; 83·29% [82·15 to 84·42]) chewing tobacco users lived in the south Asia region. Prevalence among young people aged 15–19 years was over 10% in seven locations in 2019. Although global age-standardised prevalence of smoking tobacco use decreased significantly between 1990 and 2019 (annualised rate of change: –1·21% [–1·26 to –1·16]), similar progress was not observed for chewing tobacco (0·46% [0·13 to 0·79]). Among the 12 highest prevalence countries (Bangladesh, Bhutan, Cambodia, India, Madagascar, Marshall Islands, Myanmar, Nepal, Pakistan, Palau, Sri Lanka, and Yemen), only Yemen had a significant decrease in the prevalence of chewing tobacco use, which was among males between 1990 and 2019 (−0·94% [–1·72 to –0·14]), compared with nine of 12 countries that had significant decreases in the prevalence of smoking tobacco. Among females, none of these 12 countries had significant decreases in prevalence of chewing tobacco use, whereas seven of 12 countries had a significant decrease in the prevalence of tobacco smoking use for the period. Interpretation Chewing tobacco remains a substantial public health problem in several regions of the world, and predominantly in south Asia. We found little change in the prevalence of chewing tobacco use between 1990 and 2019, and that control efforts have had much larger effects on the prevalence of smoking tobacco use than on chewing tobacco use in some countries. Mitigating the health effects of chewing tobacco requires stronger regulations and policies that specifically target use of chewing tobacco, especially in countries with high prevalence.

Incidence, prevalence and disability associated with neurological disorders in Italy between 1990 and 2019: an analysis based on the Global Burden of Disease Study 2019.

Abstract: Neurological conditions are highly prevalent and disabling, in particular in the elderly. The Italian population has witnessed sharp ageing and we can thus expect a rising trend in the incidence, prevalence and disability of these conditions. We relied on the Global Burden of Disease 2019 study to extract Italian data on incidence, prevalence and years lived with a disability (YLDs) referred to a broad set of neurological disorders including, brain and nervous system cancers, stroke, encephalitis, meningitis, tetanus, traumatic brain injury, and spinal cord injury. We assessed changes between 1990 and 2019 in counts and age-standardized rates. The most prevalent conditions were tension-type headache, migraine, and dementias, whereas the most disabling were migraine, dementias and traumatic brain injury. YLDs associated with neurological conditions increased by 22.5%, but decreased by 2.3% in age-standardized rates. The overall increase in prevalence and YLDs counts was stronger for non-communicable diseases with onset in old age compared to young to adult-age onset ones. The same trends were in the opposite direction when age-standardized rates were taken into account. The increase in YLDs associated with neurological conditions is mostly due to population ageing and growth: nevertheless, lived disability and, as a consequence, impact on health systems has increased. Actions are needed to improve outcome and mitigate disability associated with neurological conditions, spanning among diagnosis, treatment, care pathways and workplace interventions.

Social distancing measures for COVID-19 are changing winter season.

Abstract: Health authorities worldwide have adopted measures of social distancing and movement restrictions, in addition to other public health measures to reduce exposure and to suppress interhuman SARS-CoV-2 transmission. In Italy, a national lockdown with school closure was introduced from March to May 2020. From November 2020, Italy has been divided into zones according to regional epidemiological data, with primary schools reopened, associated with the mandatory use of face masks and different levels of social distance measures. For children with symptoms suggestive of COVID-19, the surveillance mechanism for the control of SARS-CoV-2 infection is based on the performance of a real-time PCR on a nasopharyngeal swab. A diagnostic test has been introduced at the tertiary-level university hospital, …

Effects of Intraoperative Auditory Stimulation on Pain and Agitation on Awakening After Pediatric Adenotonsillectomy: A Randomized Clinical Trial.

Abstract: Importance Severe pain on awakening (POA) and emergence delirium (ED) are common following pediatric adenotonsillectomy. Effective preventive interventions are lacking. Objective To determine the effects of intraoperative auditory stimulation on reduction of POA and ED after pediatric adenotonsillectomy. Design, setting, and participants Single-center, double-blinded, 4-armed, randomized clinical trial of children undergoing adenotonsillectomy from March 2018 to May 2019 at a tertiary care pediatric referral center. Interventions Children were randomized to 1 of the following groups: auditory stimulation with music, auditory stimulation with noise, ambient noise insulation with masking earplugs, and a control group receiving no intervention. Ear inserts were placed in the operating room once general anesthesia was administered. Stimulation parameters were based on the preoperative audiological evaluation and the appropriate fitting of the transduction system, including ambient noise level monitoring. Main outcomes and measures The primary outcome was POA levels measured on 10-point scales according to age-appropriate validated tools. The secondary outcome was ED levels assessed according to the Pediatric Anesthesia Emergence Delirium 20-point scale. Results A total of 104 consecutive healthy children (median [interquartile range] age at surgery, 5.0 [3.8-6.4] years) were included in the analysis. Music had a large effect size on POA (0.63; 98% CI, 0.43-0.84) and a medium effect size on ED (0.47; 98% CI, 0.21-0.75), while noise had a medium effect size on POA (0.47; 98% CI, 0.22-0.73) and a large effect size on ED (0.63; 98% CI, 0.44-0.85) compared with controls. The earplugs group showed a small effect size on POA and ED. Considering a clinically meaningful threshold of greater than 4 for POA and 10 or greater for ED at dichotomized analysis, a large effect size was achieved by music (1.39; odds ratio [OR], 0.08; 98% CI, 0.02-0.29; and 0.84; OR, 0.22; 98% CI, 0.06-0.75, respectively) and noise (0.97; OR, 0.17; 98% CI, 0.05-0.6; and 1.48; OR, 0.07; 98% CI, 0.02-0.26, respectively), while earplugs resulted in a small effect size. Conclusions and relevance In this randomized clinical trial, children undergoing adenotonsillectomy who received intraoperative auditory stimulation demonstrated a clinically meaningful decrease in POA and ED in the immediate postoperative period. Further research is needed to assess whether intraoperative auditory stimulation may decrease POA and ED in children undergoing other types of surgical procedures.

High-school students and self-injurious thoughts and behaviours: clues of emotion dysregulation.

Abstract: Suicide attempts and self-harm in adolescence are a major public health concern: they are among the main causes of disability-adjusted life-years worldwide, with severe long-term health consequences in terms of mental illness and psychiatric hospitalisation and a significantly increased risk of suicide. Several studies recently focused on the hypothesis that adolescents may be particularly vulnerable to emotional dysregulation and on the relation between problems with emotion regulation and suicidal and self-harming behaviours. Italian epidemiological data about prevalence of these behaviours at the community level are lacking. Our study aimed to estimate the prevalence of self-injurious thoughts and behaviours (SITBs) in a representative sample of community adolescents, and to examine the association between SITBs and the emotional and behavioural profiles. Anonymous self-report questionnaires were completed by 1507 students aged 11–18 years from 24 high schools in the North-eastern Italian region of Friuli Venezia Giulia. Information was collected on SITBs, on the socio-environmental context, and on the psychological profile (‘Achenbach’s YSR questionnaire 11–18, Multidimensional Test of Self-harm and Multi-Attitude Suicide Tendency Scale). Overall, 11.1% of adolescents reported self-harming behaviours without suicide ideation or attempts, 6.4% declared having thought to suicide without acting a suicide attempt or self-harm, 1.4% declared having attempted suicide and really thought to take away their life. Access to health services following a suicide thought, a self-harming behaviour or suicide attempt was infrequent, particularly for suicide ideation. At the YSR, all the SITBs groups reported high scores in almost all scales, with the most evident differences in the self-harming groups in which adolescents reported significantly higher scores in all scales, both internalising and externalising. An emotion dysregulation profile was found in almost all the groups. This study provides us with an estimate of the prevalence of SITBs in the adolescent population and confirms the importance of further investigating the association between SITBs and emotion dysregulation. The naturalistic setting of community studies appears to be useful for studies in this field, and it allows to approach the onerous and often neglected issue of adolescent suicidality.

Safety and family satisfaction of a home-delivered chemotherapy program for children with cancer

Abstract: Home chemotherapy programs for children with cancer are safe and feasible, and their impact on the quality of life has been reported in different countries. A home chemotherapy program was implemented between 2011 and 2019 in an Italian region. This pilot study investigates its safety and feasibility, along with parental satisfaction. Patients between 0 and 18 years diagnosed with malignancy were included. Deceased patients and patients whose families moved abroad or interrupted contact with the service were excluded. Adverse events comprised immediate deterioration of the patient’s condition, equipment failure, errors in drug storage, dose or patient identification and personnel safety issues. Parental satisfaction was explored through an email survey of 32 Likert-type and short open questions. Thirty-five patients received 419 doses of intravenous chemotherapy at home (cytarabine, vincristine, vinblastine). No adverse events were reported. Twenty-three families out of 25 eligible completed the survey. Most reported being “very satisfied” with the possibility of maintaining a work/domestic routine and reducing time and financial burden of hospital access. Most were “very satisfied” with the opportunity for their child of being less troubled by the treatment. Besides, most reported being “very satisfied” with the chance for healthy siblings of maintaining their routine and coping with their brother/sister’s disease. Most perceived the program as safe. All families recommended extending the program to all children in the region. This first Italian study supports home chemotherapy as safe and effective, positively influencing the quality of life for children and their families.

Adolescents with somatic symptom disorder experienced less anxiety and depression than healthy peers during the first COVID-19 lockdown.

Abstract: Adolescents with mental health disorders are a high-risk population and problems during COVID-19 lockdowns have included increasing, widespread anxiety, fear, anger and uncertainty. Somatic symptom disorder (SSD) is characterised by disproportionate thoughts, feelings and behaviours about physical symptoms associated with the distress and disruption of everyday functioning. SSD accounts for 15-25% of adolescent mental health cases in primary care paediatric settings,3 and 8.6% of non-traumatic adolescent pain in emergency departments.4.

Covid-19: Quale Modello di Malattia?

Abstract: In medicina da sempre si tenta di elaborare dei modelli per spiegare l’origine delle malattie e rendere conto dei diversi fattori causali. In questo articolo non ci occuperemo tanto di modelli matematici (elaborati per cercare di descrivere e “prevedere” l’evoluzione e la diffusione delle malattie attraverso l’analisi di funzioni costruite su numerose variabili e assunti), ma piuttosto di modelli “causali” con l’obiettivo di dare il giusto peso alle seguenti famiglie di determinanti: y genetica; y fattori modificanti (fattori di rischio in generale e comportamenti legati agli “stili di vita”); y ambiente, da intendersi in senso lato: non solo l’aspetto fisico/chimico (temperatura, umidità, altitudine, clima, inquinamento...), ma anche quello biologico (la presenza di virus e batteri, ma anche del microbioma); quello educativo, sociale, culturale, economico, politico, e non ultimo quello più strettamente sanitario (l’organizzazione dei servizi territoriali e ospedalieri, di prevenzione, cura, riabilitazione, palliazione; i posti letto, le attrezzature, i farmaci e i vaccini, le dotazioni strumentali, il personale, i locali idonei, il sistema informativo e altro ancora).

Fifteen-Years Follow-Up in a Cohort of Children with Functional Gastrointestinal Disorders: Prevalence and Risk Factors to Develop Neuropsychiatric Disorders and Other Comorbidities.

Abstract: Background: Functional gastrointestinal disorders (FGIDs) are chronic and recurrent disorders, which affect up to 23% of children and adolescents and represent 50% of gastroenterological accesses. The association between FGIDs diagnosed at paediatric age and the onset of migraine or headache and neuropsychiatric diseases in adolescence and adulthood is widely reported in the literature. However, there is still limited knowledge about the long-term prognosis and risk factors for neuropsychiatric pathologies and other comorbidities. Aim: The aim is to assess the prevalence and persistence of FGIDs as well as the occurrence of migraine or headache and neuropsychiatric disorders in a cohort of patients diagnosed with FGIDs 15 years ago compared with a control group of peers. Materials and methods: We enrolled a group of patients diagnosed with FGIDs at paediatric age, at least 10 years ago (FGIDs group, n = 79; median age 23), and control subjects (control group, n = 201; median age 23). In both groups, an online questionnaire created explicitly for the study was submitted in order to investigate the presence of chronic intestinal diseases, migraine, headache or neuropsychiatric disorders. Results: 45.6% (36 out of 79) of patients previously diagnosed with FGIDs still suffer from FGIDs versus 12% (24 out of 201) of healthy controls (p < 0.0001). The prevalence of chronic organic gastrointestinal disorders was comparable in the two groups (2.5% in FGIDs group versus 1% in healthy group, p = 0.3). Thirty-three percent (26 out of 79) of FGIDs patients reported headache or migraine versus 13% (26 out of 201) of healthy peers (p < 0.001). No differences were found regarding the prevalence of anxiety and depression. Conclusion: The outcome at 15 years of FGIDs was characterized by a high prevalence of persisting functional symptoms along with a significant incidence of headaches and migraines.

Essential Infantile Esotropia: A Course of Treatment From Our Experience

Abstract: Background: Essential infantile esotropia (EIE) is the most common type of childhood esotropia. Although its classical approach is surgical, less invasive techniques have been proposed as an adjunct or alternative to traditional surgery. Among them, chemodenervation with botulinum toxin (BT) has been investigated, showing variable and sometimes conflicting results. Objectives: To compare the outcomes of bilateral BT injection and traditional surgery in a pediatric population with EIE in order to optimize and standardize the therapeutic approach. Other purposes are to evaluate whether early intervention may prevent the onset of vertical ocular deviation (which is part of the clinical picture of EIE) and/or influence the development of fine stereopsis, and also to assess changes in refractive status over time among the enrolled population. Methods: A retrospective consecutive cohort study was conducted in 86 children aged 0-48 months who underwent correction of EIE. The primary intervention in naive subjects was either bilateral BT injection (36 subjects, "BT group") or strabismus surgery (50 subjects, "surgery group"). Results: Overall, BT chemodenervation (one or two injections) was effective in 13 (36.1%) subjects. With regard to residual deviation angle, the outcomes at least 5 years after the last intervention were overlapping in children receiving initial treatment with either injection or surgery; however, the success rate of primary intervention in the surgery group was higher, and the average number of interventions necessary to achieve orthotropia was smaller. Both early treatment with chemodenervation and surgery at a later age were not found to prevent the onset of vertical ocular deviation, whereas, surprisingly, the percentage of subjects developing fine stereopsis was higher in the surgery group. Finally, with regard to the change in refractive status over time, most of the subjects increased their initial hyperopia, whereas 10% became myopic. Conclusions: Our data suggest that a single bilateral BT injection by age 2 years should be considered as the first-line treatment of EIE without vertical component; whereas, traditional surgery should be considered as the first-line treatment for all other cases and in subjects unresponsive to primary single BT injection.

Minimally-Invasive Surgical Approach to Congenital Dacryostenosis: Proposal for a New Protocol

Abstract: Background. Congenital dacryostenosis is one of the most common ophthalmological disorders in infants, with a high spontaneous resolution rate. In patients unresponsive to conservative treatment, the first-line approach is lacrimal drainage system probing, thought there is no clear consensus on optimal timing of surgery. The optimal treatment of patients unresponsive to primary probing is also controversial. Objectives. The aim of this study is to assess the optimal timing of probing in children with congenital dacryostenosis. Other purposes are to evaluate the efficacy of repeated probing and dacryointubation in patients unresponsive to the initial surgery without evident lacrimal outflow dysgenesis, and to determine the epidemiology of these maldevelopments. Methods. A retrospective consecutive cohort study was conducted in 625 eyes of 457 patients aged 7-48 months who underwent surgery for dacryostenosis. Patients were divided into 4 cohorts according to the timing of surgery. Data were analyzed using Fisher’s test. Results. The success rate of primary probing was high, without significant differences between cohorts. One-third of recurrences were related to maldevelopments, the other two-thirds were treated with a second probing or dacryointubation, with high success rates, that did not significantly differ between the procedures. All cases unresponsive to the second surgery were resolved with dacryointubation. Conclusions. Probing is highly effective and its outcome is not affected by timing of surgery. Nevertheless, we advocate for early intervention, in order to identify possible maldevelopments, which require more invasive management. In patients unresponsive to primary probing, without evident maldevelopments, repeated probing should still be considered as the first-line approach, since it’s less invasive but similarly effective to dacryointubation.

Problem-based learning for in-service training on breastfeeding in Friuli Venezia Giulia, Italy.

Abstract: Background Problem-Based Learning (PBL) is extensively used in pre- and post-graduate teaching programmes. However, it has been seldom used for in-service training and continuing medical education. We aimed to develop a PBL curriculum for a short in-service training on breastfeeding for maternal and child health professionals, and to assess the effect of these courses on their knowledge and skills. Also, the project aimed at increasing exclusive breastfeeding rates and duration in an Italian region. Methods After initial training on PBL and an assessment of the learning needs of about 400 health professionals, a small working group developed learning objectives, designed a curriculum, produced manuals, and shaped assessment tools for a new PBL course on breastfeeding. The field test of the new course allowed selection of the tutors for the scaling up of the training to the whole region. During this extension phase, participants were asked to complete an evaluation questionnaire. In addition, the health professionals who attended the PBL courses in 2019 were asked to complete an online survey to assess knowledge, attitudes and practices (KAP) just before, soon after the course, and 4-6 months later. Results The new 29 - hour PBL course, to be delivered in four days over four consecutive weeks, gives priority to tutorial groups and practical activities (71% of the total time). Supervised clinical practices absorb 16% of time. Ethics, communication and woman-centred clinical management content run throughout the four days and all activities. The three manuals, for tutors, participants and practical activities, facilitate the tasks and performance of tutors and participants. After the field test, 32 regional tutors ran courses for 562 health professionals. The analysis of the evaluation showed a high level of satisfaction for perceived effectiveness, relevance to practice, and educational quality. The KAP questionnaires indicated a general improvement after the course and retention after 4-6 months. Conclusions Despite some predictable shortcomings, this new PBL approach for short in-service training courses on breastfeeding showed encouraging results as far as participants' satisfaction and KAP are concerned. The possible effects on rates and duration of exclusive breastfeeding need further research.
