Parents' and caregivers' role toward childhood vaccination in Albania: assessment of predictors of vaccine hesitancy.

Background: Vaccination has saved millions of lives through the protection of individuals and populations from communicable diseases. Vaccine hesitancy, defined as the delay in acceptance or refusal of vaccines despite the availability of vaccination services, has become a growing global concern. The objective of this study was to investigate parents'/caregivers' hesitancy toward childhood vaccination and its predictors in Albania. Study design: A cross-sectional survey was conducted. Methods: The data comes from a survey conducted on a sample of parents/caregivers (89.6% mothers) of children aged 6 months to 8 years at health care vaccination centers in seven Albanian cities from December 2020 to February 2021. Parents/caregivers (one per child) were interviewed by trained healthcare staff using a standardized questionnaire on six main content domains, including immunization behavior, beliefs about vaccine safety and efficacy, attitudes about vaccines, vaccination confidence, estimation of vaccine delay, and the intention to immunize children against SARS-CoV-2, and a self-reported hesitancy. The Albanian Ministry of Health approved the questionnaire, after it was translated, validated and adapted to the local setting. Statistical analyses included independent sample t-tests (p<0.05) and a logistic regression (OR; 95% C.I.). Results: A total of 475 parents/caregivers of children aged from 6 months to 8 years, attending childhood vaccination in public health services, were interviewed. To the question "how hesitant you are about childhood vaccination", a high number of parents/caregivers (46%) responded that they do not feel hesitant at all, and 32% were not hesitant, a small number of parents/caregivers said they are very hesitant (5%) or somewhat hesitant (12%). A binary logistic model was fitted to the data to test the hypothesis regarding the relationship between parental vaccine hesitancy and possible predictors. A lower parental attitude toward childhood vaccines (OR = 3.7; 95% C.I. 1.102-12.421), a health center with a high vaccine delay (OR = 2.878; C.I. 95% 1.735-4.773), and low confidence in health staff information (OR = 2.042; 95% C.I. 1.156-3.605) were all independent predictors of parental vaccine hesitancy. Regarding intention to vaccinate children against COVID-19, when available, nearly 75% of parents/caregivers showed hesitancy. Conclusions: Our results highlighted the role of positive parents'/caregivers' attitudes toward childhood vaccines followed by high staff confidence and good health center organization in order to deal with vaccine hesitancy, particularly for traditional and well-known childhood vaccines. Nevertheless, the hesitancy can be a critical barrier for childhood vaccination when we have to introduce a new vaccine, as is demonstrated in the recent vaccination campaign against the ongoing pandemic of SARS-CoV2.

SEVERE HYPOKALEMIA INDUCED RHABDOMYOLYSIS BY PRIMARY HYPERALDOSTERONISM COEXISTENT WITH RECURRENT BILATERAL RENAL CALCULI.

Primary Hyperaldosteronism is one of the causes of secondary hypertension. Primary Hyperaldosteronism is characterised by an increase in the production of aldosterone and the inhibition of the secretion of renin. We described here a case with rhabdomyolysis and severe hypokalemia as a cause of primary hyperaldosteronism. The creatine kinase, aldosterone were very high. Cortisol values and midnight salivary cortisol values were within normal range. The patient had been under treatment for high blood pressure for more than six years, with ARBs and calcium channel blockers. During this time the potassium values measured frequently every year were below normal range, but primary hyperaldosteronism was not suspected.

Factors associated with hypertension prevalence, awareness, treatment and control among participants in the International Mobility in Aging Study (IMIAS).

The aim of this study is to assess the factors associated with hypertension prevalence, awareness, treatment, and control, in the elderly populations of the International Mobility in Aging Study (IMIAS). Approximately 200 men and 200 women aged 65-74 years were recruited at each site (n=1995) during IMIAS' 2012 baseline survey at five cities: Kingston (Canada), Saint-Hyacinthe (Canada), Tirana (Albania), Manizales (Colombia) and Natal (Brazil). Blood pressure and anthropometric measurements were taken at participants' homes. Hypertension prevalence ranged from 53.4% in Saint-Hyacinthe to 83.5% in Tirana. Diabetes and obesity were identified as risk factors in all cities. More than two-thirds of hypertensive participants were aware of their condition (from 67.3% in Saint-Hyacinthe to 85.4% in Tirana); women were more aware than men. Awareness was positively associated with diabetes in Kingston, Manizales and Natal. Though most of those aware of their hypertensive condition were being treated pharmacologically, associations between awareness and physical activity and refraining from smoking were weak. Control among treated hypertensive participants was low, especially in Tirana and Natal. Diabetes and physical inactivity were associated with poor hypertension control. Hypertension is common in the older populations of IMIAS. Diabetes is strongly associated with hypertension prevalence, awareness and lack of control of hypertension. The fact that awareness is not strongly associated with healthy behaviours suggests that antihypertensive medication is not accompanied by non-pharmacological therapies. Improved health behaviours could strengthen hypertension control. Efforts should be made to increase men's awareness of hypertension. Hypertension control in diabetic patients is a challenge.

The mobility gap between older men and women: the embodiment of gender.

OBJECTIVES: To present the study design and baseline results of the longitudinal International Mobility in Aging Study (IMIAS) on gender differences in physical performance and mobility disability prevalence in five diverse societies. METHODS: Data are from surveys on random samples of people aged 65-74 years at Canadian (Kingston, Ontario; Saint-Hyacinthe, Quebec), Mediterranean (Tirana, Albania) and Latin American sites (Natal, Brazil; Manizales, Colombia) (N=1995). Mobility disability was defined as reporting difficulty in walking 400m or climbing stairs. Activities of daily living (ADL) disability was based on any self-reported difficulty in five mobility-related ADLs. The short physical performance battery (SPPB) was used to assess physical performance. Poisson regression models were fitted to estimate prevalence ratios. RESULTS: Age-adjusted prevalence of low SPPB, mobility disability and ADL disability were higher in women than in men in all sites except for Kingston. After adjustment for education and income, gender differences in SPPB and ADL disability attenuated or disappeared in Saint-Hyacinthe and Manizales but remained large in Tirana and Natal and mobility disability remained more frequent in women than in men at all sites except Kingston. After further adjustment by chronic conditions and depressive symptoms, gender differences in mobility remained large at all sites except Kingston but only in Tirana did women have significantly poorer physical performance than men. DISCUSSION: Results provide evidence for gender as a risk factor to explain poorer physical function in women and suggest that moving toward gender equality could attenuate the gender gap in physical function in old age.

Prevalence of microalbuminuria and risk factor analysis in type 2 diabetes patients in Albania: the need for accurate and early diagnosis of diabetic nephropathy.

BACKGROUND: Microalbuminuria is often the first sign of renal dysfunction in diabetes. This study aimed to investigate the prevalence of microalbuminuria in Albanian type 2 diabetes patients and its association with other cardiovascular risk factors. METHODS: Three hundred and twenty-one patients with type 2 diabetes attending, diabetes centers in Albania were enrolled in this cross-sectional, multicenter study. The subjects, aged 40-70 years, had no known proteinuria or other kidney disease. Pregnant women and patients with acute infections were excluded. Data including waist circumference, duration of diabetes and history of hypertension were obtained by questionnaire. Blood samples were drawn after 12 h overnight fasting to measure glycosylated hemoglobin (HbA1c), serum cholesterol, triglyceride and creatinine. Microalbuminuria was assessed using dipstick kits in early morning urine samples. RESULTS: The prevalence of normoalbuminuria was 56.3%, microalbuminuria 40.8% and macroalbuminuria 2.8%. Systolic and diastolic blood pressure (p<0.01), HbA1c (p<0.01) and fasting plasma glucose (p<0.001) were significantly higher in microalbuminuric than in normoalbuminuric subjects. Independent risk factors for microalbuminuria were duration of diabetes (OR: 2.785, 95% CI: 1.156-3.759), systolic blood pressure (OR: 2.88, 95% CI: 1.85-6.85) and waist circumference (OR: 2.15, 95% CI: 1.01-5.45) in males and poor glycemic control (OR: 4.51, 95% CI: 1.45-13.98), duration of diabetes (OR: 2.568, 95% CI: 1.702-3.778) and waist circumference (OR: 4.87, 95% CI: 1.80-13.11) in females. CONCLUSIONS: The high proportion of type 2 diabetes patients with microalbuminuria raises implications for health policy in Albania. Screening programs and optimized control of modifiable risk factors are needed to reduce the risk of diabetic nephropathy.

First outbreak of norovirus in Albania.

AIMS: Noroviruses (NoVs) represent the most important enteric viruses responsible for acute gastroenteritis world-wide. This study objective is to characterize the first outbreak of NoV that occurred in Ballsh, a small city in Albania. METHODS AND RESULTS: Stool specimens were collected from people attending to the hospital. Samples were also collected from the aqueduct for bacteriological and virological tests. Overall 33 stools and five drinking water samples were collected, respectively, from the hospital in Ballsh and from the municipal aqueduct. No water samples were scored positive whereas ten stool samples (30.3%) were scored GGII NoV positive. All the GGII isolates were identified as GGII·4 genotype, and no GGI was identified. The alignment and protein analysis were performed using, respectively, ClustalV and the mega 4 software. CONCLUSIONS: This is the first report of NoV GGII·4 in Albania causing an outbreak. The genetic analysis showed several point mutations and amino acid substitutions with respect to the international strains. SIGNIFICANCE AND IMPACT OF STUDY: Over the last decades, Albania has suffered from different outbreaks as cholera, poliomyelitis, hepatitis A and now, for the first time, it has been documented an outbreak of NoV.

Type 2 diabetes in Tirana City, Albania: a rapid increase in a country in transition.

AIMS: To determine how the prevalence of Type 2 diabetes mellitus has changed in Tirana, the capital of Albania, over 20 years. METHODS: Cluster sampling was used to select 700 households including 1540 adults 25 years of age and over in Tirana City, Albania in 2001. RESULTS: Of 1540 potential subjects, 1120 participated (response rate 72.7%). Using the 1985 WHO criteria to provide comparability with earlier data, the overall prevalence of Type 2 diabetes mellitus in the age group 25+ was 6.3% (95% confidence interval 4.8-7.7); 6.9% (4.8-9.1%) male; 5.6% (3.8-7.5%) female. The age-adjusted prevalence in those aged 25+ was 5.4%. Of respondents, 3.4% were known to have diabetes, and 2.9% were newly identified through the survey. The prevalence of diabetes increased with age, although among men there was a slight decline after age 65. Impaired glucose tolerance was found in a further 2.9% of respondents, again increasing with age. The prevalence of diabetes has increased significantly since 1980, doubling in the age group 50+. Use of the 1999 WHO diagnostic criteria produces a higher unadjusted prevalence, at 9.7% (8-11.4%). In a logistic regression model, obesity and family history were independent determinants of the probability of having diabetes. Among those known to have diabetes, control was poor. CONCLUSIONS: The prevalence of diabetes in Albania has increased rapidly, consistent with what has been seen in other countries undergoing rapid modernization. It is likely to increase further in the future, with important implications for health policy.

Outbreak of paralytic poliomyelitis in Albania, 1996: high attack rate among adults and apparent interruption of transmission following nationwide mass vaccination.

After >10 years without detection of any cases of wild virus-associated poliomyelitis, a large outbreak of poliomyelitis occurred in Albania in 1996. A total of 138 paralytic cases occurred, of which 16 (12%) were fatal. The outbreak was due to wild poliovirus type 1, isolated from 69 cases. An attack rate of 10 per 100,000 population was observed among adults aged 19-25 years who were born during a time of declining wild poliovirus circulation and had been vaccinated with two doses of monovalent oral poliovirus vaccines (OPVs) that may have been exposed to ambient temperatures for prolonged periods. Control of the epidemic was achieved by two rounds of mass vaccination with trivalent oral poliovirus vaccine targeted to persons aged 0-50 years. This outbreak underscores the ongoing threat of importation of wild poliovirus into European countries, the importance of delivering potent vaccine through an adequate cold chain, and the effectiveness of national OPV mass vaccination campaigns for outbreak control.

Community-based surveillance of cardiovascular risk factors in Geneva: methods, resulting distributions, and comparisons with other populations.

OBJECTIVES: This paper presents the results of an ongoing community-based surveillance program of cardiovascular risk factors in Geneva, Switzerland, using percentiles with their associated 95% confidence intervals and compares the Genevan results with published data from international surveys reporting percentiles. METHODS: A random survey of adults ages 35 to 74 years was conducted from 1993 to 1994. Confidence intervals for percentiles based on parametric and non-parametric methods are given. RESULTS: The distribution of total cholesterol was shifted upward with increasing age. The median reached a maximum at 55-64 years among men (5.7 mmol/L) and at 65-74 years among women (5.9 mmol/L), and remained relatively stable thereafter. In both genders, systolic and, less so, diastolic blood pressure increased progressively with advancing age. The median daily energy intake among men declined from 2,390 kcal at age 35-44 years to 2,169 kcal at age 65-74 years, while among women it remained stable at about 1,900 kcal. In both males and females, the relative intake of saturated fat was stable throughout life (14 to 13%). The median body mass index (BMI) was about 25 kg/m2 across all age groups among men, but increased with age among women, with a peak of 23.6 kg/m2 occurring at ages 65-74 years. Compared with U.S. and western European surveys, Genevan men and women had lower total plasma cholesterol and Genevan women tended to have lower BMIs. CONCLUSIONS: Percentiles with their associated precision appear particularly well suited for international comparison of surveillance data. They could be used in the future to monitor shifts in distributions resulting from mass prevention strategies.
