Deficijencija B12 vitamina kod deteta majke na veganskoj ishrani

Vitamin B12 deficiency usually occurs in exclusively breastfed infants whose mothers have pernicious anaemia or are vegetarian. Early treatment of vitamin B12 deficiency in infants can prevent potentially neurologic sequelae. A male child aged 13 months has been hospitalized due to failure to thrive, feeding problems, pallor, weakness and hypotonia. During the pregnancy mother did not eat meat and during lactation she also excluded eggs and milk. The child was exclusively breastfed. Laboratory investigations showed a haemoglobin level of 3.5 g/dL, haematocrit 10%, red blood cell count of 0.99 × 1012/L, white blood cell count of 4.23 × 109 /L and platelet count of 55 × 109 /L. Vitamin B12 level was low. A bone marrow aspiration finding was consistent with megaloblastic anaemia. The magnetic resonance imaging showed brain atrophy. Vitamin B12 in a dose of 10µg per kg was applied intramuscularly daily for 2 weeks, then once weekly. Three days after initiating B12 vitamin therapy there was an improvement in the blood count with the gradual improvement of neurological state. Vitamin B12 deficiency is a treatable cause of pancytopenia and neurological dysfunction in children and should be considered as differential diagnosis in an infant with neurological symptoms.Deficijencija B12 vitamina se obično javlja kod odojčadi koja su na prirodnoj ishrani a čije majke imaju pernicioznu anemiju ili su vegetarijanci. Pravovremeno lečenje deficijencije B12 vitamina kod odojčadi može da prevenira potencijalne neurološke posledice. Malo muško dete uzrasta 13 meseci je hospitalizovano zbog nenapredovanja, problema sa hranjenjem, bledila, slabosti i hipotonije.Tokom trudnoće majka nije jela meso dok je tokom dojenja iz ishrane isključila i jaja i mleko. Dete je isključivo dojeno. U laboratorijskim nalazima nivo hemoglobina je iznosio 3,5 g/dl, hematokrit 10%, broj eritrocita je bio 0.99×1012/L, broj leukocita 4.23×109 /L i broj trombocita 55×109 /L. Nivo B12 vitamina je bio snižen. Nalaz biopsije kostne srži ukazivao je na megaloblastnu anemiju. Na magnetnoj rezonanci endokranijuma viđena je atrofija mozga. Vitamin B12 u dozi od 10 mikrograma/kg primenjen je intramuskularno svakodnevno tokom 2 nedelje, potom jednom nedeljno.Tri dana od započinjanja terapije zabeleženo je poboljšanje hematoloških vrednosti uz postepeno poboljšanje neurološkog statusa. Deficijencija B12 vitamina je uzrok pancitopenije i neurološke disfuncije kod dece koju je moguće lečiti. Kod odojčeta sa neurološkim simptomima ova deficijencija treba da bude razmotrena kao diferencijalna dijagnoza

The most important diseases in dogs and cats and new trends in immunoprophylaxis

Značajan segment profesionalnog angažovanja doktora veterinarske medicine predstavlja tzv. mala praksa; često nazvana i luksuzna, s obzirom na, većim delom, sentimentalnu vrednost pacijenata. Najčešće se radi o psima i mačkama koji u veterinarsku ambulantu (kliniku) dolaze i povodom sprovođenja imunoprofilaktičkih mera, tj. vakcinacija, kojima se sprečavaju odnosno kontrolišu najznačajnije infektivne bolesti ove dve vrste životinja. Ne razmatrajući osnovne preduslove za sticanje adekvatne zaštite odnosno pravilne reakcije na vakcinu, u radu se ukazuje na nove sisteme imunoprofilakse i upotrebu novih imunogena. Naime, za vakcinaciju pasa na tržištu se nalaze u različitim formulacijama kako inaktivisani tako i atenuisani imunogeni parvovirusa pasa, atenuisani adenovirusi i paramiksovirusi (štenećak i parainfluenca). U slučaju vakcinacije mačaka, kontrolišu se kalici, herpes, parvovirusne i retrovirusne infekcije, kao i hlamidioza mačaka. Neka infektivna oboljenja pasa i mačaka su zoonoze. Tako se, na primer, infekcije sa leptospirama kontrolišu inaktivisanim vakcinama koje tradicionalno sadrže serotipove koji su od značaja kako za pse tako i za ljude (serotipovi Canicola i Icterohaemorrhagiae). Od značaja je svakako i činjenica da se u populacijama pasa i mačaka pojavljuju i neki drugi serotipovi bakterije L. interrogans. Dobro je poznata epizootiološka činjenica da se psi pojavljuju kao rezervoari gore napomenutih serotipova ali, po svemu sudeći, i mačke igraju značajnu ulogu u održavanju leptospiroze u našem regionu. Postojanje maternalnog imuniteta nije i jedini problem prilikom vakcinacije mladih životinja. Naime, u nekim slučajevima, uspešno sproveden protokol vakcinacije, na primer, protiv parvovirusne infekcije pasa, obezbeđuje višegodišnju zaštitu pa je u takvim slučajevima vakcinacija jednom godišnje kontraindikovana.A significant segment of professional engagement for doctor of veterinary medicine is the so called. small practice; often referred as luxury, given the largely sentimental value to patients. Frequently, it comes to dogs and cats that in veterinary clinic (clinic) come because of the occasion for the implementation of immunoprophylactic measures ie. vaccinations that prevent or control the most important infectious diseases of these two species. Not considering the basic prerequisites for obtaining of adequate protection or proper reaction to the vaccine, the paper points to the new systems of immunoprophylaxis and use of new immunogens. Namely, for the dogs vaccination, in market are in various formulations inactivated and attenuated immunogenic parvovirus, adeno and attenuated paramyxovirus (distemper and parainfluenza) viruses. In the case of vaccination of cats, calici, herpes, parvo and retro viral infections and chlamydiosis of cats controlled. Some infectious diseases of dogs and cats are zoonoses. For example, infection with leptospires, control is with inactivated vaccines traditionally serotypes that are of importance for both dogs and humans (serotypes canicola and icterohaemorrhagiae). Of importance is certainly the fact that in populations of dogs and cats appear and some other serotypes of L. interrogans. Well known is epidemiological fact that dogs appear as reservoirs of the serotypes, but apparently cats play an important role in the maintenance of leptospirosis in our region. The existence of maternal immunity is not the only problem during the vaccination of young animals. Namely, in some cases successfully executed the protocol of vaccination, for example against parvoviral infections of dogs, provides long-term protection and is in such cases, vaccination once per year, is contraindicated

Organised crime and international aid subversion: evidence from Colombia and Afghanistan

Scholarly attempts to explain aid subversion in post-conflict contexts frame the challenge in terms of corrupt practices and transactions disconnected from local power struggles. Also, they assume a distinction between organised crime and the state. This comparative analysis of aid subversion in Colombia and Afghanistan reveals the limits of such an approach. Focusing on relations that anchor organised crime within local political, social and economic processes, we demonstrate that organised crime is dynamic, driven by multiple motives, and endogenous to local power politics. Better understanding of governance arrangements around the organised crime-conflict nexus which enable aid subversion is therefore required

Worldwide trends in body-mass index, underweight, overweight, and obesity from 1975 to 2016: a pooled analysis of 2416 population-based measurement studies in 128·9 million children, adolescents, and adults.

BACKGROUND: Underweight, overweight, and obesity in childhood and adolescence are associated with adverse health consequences throughout the life-course. Our aim was to estimate worldwide trends in mean body-mass index (BMI) and a comprehensive set of BMI categories that cover underweight to obesity in children and adolescents, and to compare trends with those of adults. METHODS: We pooled 2416 population-based studies with measurements of height and weight on 128·9 million participants aged 5 years and older, including 31·5 million aged 5-19 years. We used a Bayesian hierarchical model to estimate trends from 1975 to 2016 in 200 countries for mean BMI and for prevalence of BMI in the following categories for children and adolescents aged 5-19 years: more than 2 SD below the median of the WHO growth reference for children and adolescents (referred to as moderate and severe underweight hereafter), 2 SD to more than 1 SD below the median (mild underweight), 1 SD below the median to 1 SD above the median (healthy weight), more than 1 SD to 2 SD above the median (overweight but not obese), and more than 2 SD above the median (obesity). FINDINGS: Regional change in age-standardised mean BMI in girls from 1975 to 2016 ranged from virtually no change (-0·01 kg/m2 per decade; 95% credible interval -0·42 to 0·39, posterior probability [PP] of the observed decrease being a true decrease=0·5098) in eastern Europe to an increase of 1·00 kg/m2 per decade (0·69-1·35, PP>0·9999) in central Latin America and an increase of 0·95 kg/m2 per decade (0·64-1·25, PP>0·9999) in Polynesia and Micronesia. The range for boys was from a non-significant increase of 0·09 kg/m2 per decade (-0·33 to 0·49, PP=0·6926) in eastern Europe to an increase of 0·77 kg/m2 per decade (0·50-1·06, PP>0·9999) in Polynesia and Micronesia. Trends in mean BMI have recently flattened in northwestern Europe and the high-income English-speaking and Asia-Pacific regions for both sexes, southwestern Europe for boys, and central and Andean Latin America for girls. By contrast, the rise in BMI has accelerated in east and south Asia for both sexes, and southeast Asia for boys. Global age-standardised prevalence of obesity increased from 0·7% (0·4-1·2) in 1975 to 5·6% (4·8-6·5) in 2016 in girls, and from 0·9% (0·5-1·3) in 1975 to 7·8% (6·7-9·1) in 2016 in boys; the prevalence of moderate and severe underweight decreased from 9·2% (6·0-12·9) in 1975 to 8·4% (6·8-10·1) in 2016 in girls and from 14·8% (10·4-19·5) in 1975 to 12·4% (10·3-14·5) in 2016 in boys. Prevalence of moderate and severe underweight was highest in India, at 22·7% (16·7-29·6) among girls and 30·7% (23·5-38·0) among boys. Prevalence of obesity was more than 30% in girls in Nauru, the Cook Islands, and Palau; and boys in the Cook Islands, Nauru, Palau, Niue, and American Samoa in 2016. Prevalence of obesity was about 20% or more in several countries in Polynesia and Micronesia, the Middle East and north Africa, the Caribbean, and the USA. In 2016, 75 (44-117) million girls and 117 (70-178) million boys worldwide were moderately or severely underweight. In the same year, 50 (24-89) million girls and 74 (39-125) million boys worldwide were obese. INTERPRETATION: The rising trends in children's and adolescents' BMI have plateaued in many high-income countries, albeit at high levels, but have accelerated in parts of Asia, with trends no longer correlated with those of adults.

Diminishing benefits of urban living for children and adolescents’ growth and development

Optimal growth and development in childhood and adolescence is crucial for lifelong health and well-being1–6. Here we used data from 2,325 population-based studies, with measurements of height and weight from 71 million participants, to report the height and body-mass index (BMI) of children and adolescents aged 5–19 years on the basis of rural and urban place of residence in 200 countries and territories from 1990 to 2020. In 1990, children and adolescents residing in cities were taller than their rural counterparts in all but a few high-income countries. By 2020, the urban height advantage became smaller in most countries, and in many high-income western countries it reversed into a small urban-based disadvantage. The exception was for boys in most countries in sub-Saharan Africa and in some countries in Oceania, south Asia and the region of central Asia, Middle East and north Africa. In these countries, successive cohorts of boys from rural places either did not gain height or possibly became shorter, and hence fell further behind their urban peers. The difference between the age-standardized mean BMI of children in urban and rural areas was <1.1 kg m–2 in the vast majority of countries. Within this small range, BMI increased slightly more in cities than in rural areas, except in south Asia, sub-Saharan Africa and some countries in central and eastern Europe. Our results show that in much of the world, the growth and developmental advantages of living in cities have diminished in the twenty-first century, whereas in much of sub-Saharan Africa they have amplified

Rising rural body-mass index is the main driver of the global obesity epidemic in adults

Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities(.)(1,2) This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity(3-6). Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to 2017. We show that, contrary to the dominant paradigm, more than 55% of the global rise in mean BMI from 1985 to 2017-and more than 80% in some low- and middle-income regions-was due to increases in BMI in rural areas. This large contribution stems from the fact that, with the exception of women in sub-Saharan Africa, BMI is increasing at the same rate or faster in rural areas than in cities in low- and middle-income regions. These trends have in turn resulted in a closing-and in some countries reversal-of the gap in BMI between urban and rural areas in low- and middle-income countries, especially for women. In high-income and industrialized countries, we noted a persistently higher rural BMI, especially for women. There is an urgent need for an integrated approach to rural nutrition that enhances financial and physical access to healthy foods, to avoid replacing the rural undernutrition disadvantage in poor countries with a more general malnutrition disadvantage that entails excessive consumption of low-quality calories.Peer reviewe

Height and body-mass index trajectories of school-aged children and adolescents from 1985 to 2019 in 200 countries and territories: a pooled analysis of 2181 population-based studies with 65 million participants

Summary Background Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. Methods For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease Risk Factor Collaboration. We applied a Bayesian hierarchical model to estimate trends from 1985 to 2019 in mean height and mean BMI in 1-year age groups for ages 5–19 years. The model allowed for non-linear changes over time in mean height and mean BMI and for non-linear changes with age of children and adolescents, including periods of rapid growth during adolescence. Findings We pooled data from 2181 population-based studies, with measurements of height and weight in 65 million participants in 200 countries and territories. In 2019, we estimated a difference of 20 cm or higher in mean height of 19-year-old adolescents between countries with the tallest populations (the Netherlands, Montenegro, Estonia, and Bosnia and Herzegovina for boys; and the Netherlands, Montenegro, Denmark, and Iceland for girls) and those with the shortest populations (Timor-Leste, Laos, Solomon Islands, and Papua New Guinea for boys; and Guatemala, Bangladesh, Nepal, and Timor-Leste for girls). In the same year, the difference between the highest mean BMI (in Pacific island countries, Kuwait, Bahrain, The Bahamas, Chile, the USA, and New Zealand for both boys and girls and in South Africa for girls) and lowest mean BMI (in India, Bangladesh, Timor-Leste, Ethiopia, and Chad for boys and girls; and in Japan and Romania for girls) was approximately 9–10 kg/m2. In some countries, children aged 5 years started with healthier height or BMI than the global median and, in some cases, as healthy as the best performing countries, but they became progressively less healthy compared with their comparators as they grew older by not growing as tall (eg, boys in Austria and Barbados, and girls in Belgium and Puerto Rico) or gaining too much weight for their height (eg, girls and boys in Kuwait, Bahrain, Fiji, Jamaica, and Mexico; and girls in South Africa and New Zealand). In other countries, growing children overtook the height of their comparators (eg, Latvia, Czech Republic, Morocco, and Iran) or curbed their weight gain (eg, Italy, France, and Croatia) in late childhood and adolescence. When changes in both height and BMI were considered, girls in South Korea, Vietnam, Saudi Arabia, Turkey, and some central Asian countries (eg, Armenia and Azerbaijan), and boys in central and western Europe (eg, Portugal, Denmark, Poland, and Montenegro) had the healthiest changes in anthropometric status over the past 3·5 decades because, compared with children and adolescents in other countries, they had a much larger gain in height than they did in BMI. The unhealthiest changes—gaining too little height, too much weight for their height compared with children in other countries, or both—occurred in many countries in sub-Saharan Africa, New Zealand, and the USA for boys and girls; in Malaysia and some Pacific island nations for boys; and in Mexico for girls. Interpretation The height and BMI trajectories over age and time of school-aged children and adolescents are highly variable across countries, which indicates heterogeneous nutritional quality and lifelong health advantages and risks

Status and Trends of Physical Activity Surveillance, Policy, and Research in 164 Countries: Findings From the Global Observatory for Physical Activity—GoPA! 2015 and 2020 Surveys

Background: Physical activity (PA) surveillance, policy, and research efforts need to be periodically appraised to gain insight into national and global capacities for PA promotion. The aim of this paper was to assess the status and trends in PA surveillance, policy, and research in 164 countries. Methods: We used data from the Global Observatory for Physical Activity (GoPA!) 2015 and 2020 surveys. Comprehensive searches were performed for each country to determine the level of development of their PA surveillance, policy, and research, and the findings were verified by the GoPA! Country Contacts. Trends were analyzed based on the data available for both survey years. Results: The global 5-year progress in all 3 indicators was modest, with most countries either improving or staying at the same level. PA surveillance, policy, and research improved or remained at a high level in 48.1%, 40.6%, and 42.1% of the countries, respectively. PA surveillance, policy, and research scores decreased or remained at a low level in 8.3%, 15.8%, and 28.6% of the countries, respectively. The highest capacity for PA promotion was found in Europe, the lowest in Africa and low- and lower-middle-income countries. Although a large percentage of the world’s population benefit from at least some PA policy, surveillance, and research efforts in their countries, 49.6 million people are without PA surveillance, 629.4 million people are without PA policy, and 108.7 million live in countries without any PA research output. A total of 6.3 billion people or 88.2% of the world’s population live in countries where PA promotion capacity should be significantly improved. Conclusion: Despite PA is essential for health, there are large inequalities between countries and world regions in their capacity to promote PA. Coordinated efforts are needed to reduce the inequalities and improve the global capacity for PA promotion
