Chediak-Higashi syndrome: Lessons from a single-centre case series.

BACKGROUND: Chediak-Higashi syndrome (CHS) is a rare and potentially fatal autosomal recessive disease characterized by frequent bacterial infections, bleeding tendency, oculocutaneous albinism, photosensitivity and progressive neurologic dysfunction. Owing to the rarity of this condition, the objective of this study was to describe patients with CHS. METHODS: Retrospective evaluation of patients followed in a paediatric tertiary centre of Allergy and Immunology of São Paulo, Brazil, between 1986 and 2018 with a confirmed diagnosis of CHS. Data were obtained from medical records. Demographic aspects, family history, clinical findings, laboratory data, diagnosis, treatment and outcome were described. RESULTS: A total of 14 patients (five male) were included. Clinical manifestations were first recognized at a median age of two months (at birth-20 months). Median age at diagnosis was 1.7 years (0-5 years). All patients had recurrent infections. Albinism was present in 13 patients and silvery or light hair was present in 14. Seven patients developed hemophagocytic lymphohistiocytosis (HLH); the median age at the diagnosis of HLH was 5.7 years (2.6-6.7 years) and the median interval between the diagnosis of CHS and HLH was 3.3 years (0-5 years). Four of the most recently diagnosed patients underwent bone marrow transplantation (BMT). Nine patients are deceased, and one was lost to follow-up. The median age of death was 6.7 years (3.8-22 years). Five patients died of HLH, one of lymphoma, and three of infection. All the patients who had HLH before the year of 2000 died of HLH. The two most recently diagnosed patients with HLH were able to cure the HLH, although they died of other causes. Four patients are alive, three of them after successful BMT. CONCLUSION: Thirty years of follow up showed an improvement in the prognosis in patients with CHS. The better understanding of the underlying biological mechanisms of HLH allowed the standardization of management protocols, resulting in survival improvement. BMT is the only treatment that can change CHS prognosis, which emphasizes the need for early identification of the disease.

A fast and simple method for the polymerase chain reaction-based sexing of livestock embryos.

Embryo sexing is a powerful tool for livestock producers because it allows them to manage their breeding stocks more effectively. However, the cost of supplies and reagents, and the need for trained professionals to biopsy embryos by micromanipulation restrict the worldwide use of the technology to a limited number of specialized groups. The aim of this study was to couple a fast and inexpensive DNA extraction protocol with a practical biopsy approach to create a simple, quick, effective, and dependable embryo sexing procedure. From a total of 1847 sheep and cattle whole embryos or embryo biopsies, the sexing efficiency was 100% for embryo biopsies, 98% for sheep embryos, and 90.2% for cattle embryos. We used a primer pair that was common to both species and only 10% of the total extracted DNA. The whole protocol takes only 2 h to perform, which suggests that the proposed procedure can be readily applied to field conditions. Moreover, in addition to embryo sexing, the procedure can be used for further analyses, such as genotyping and molecular diagnosis in preimplantation embryos.

Nosocomial bloodstream infections in a nationwide study: comparison between solid organ transplant patients and the general population.

BACKGROUND: The incidence of bloodstream infection (BSI) varies according to the transplanted organ. Mortality can be as high as 24%, with a significant impact on graft survival. Transplantation is a risk factor for multidrug-resistant (MDR) organisms, but comparison with a non-transplanted population in a single large cohort has not been described. METHODS: This is a prospective nationwide study (16 centers) reporting data on 2364 monomicrobial nosocomial BSIs, comparing 83 episodes in solid organ transplant patients with 2447 BSIs occurring in the general hospital population. RESULTS: The prevalence of groups of infecting organisms (gram-positive, gram-negative, and fungi) was similar between transplant patients and the general population and a similar crude mortality rate was observed (34.9% in transplant vs. 43.3% in non-transplant patients). Staphylococcus aureus was the single most frequently isolated organism in both groups, and Acinetobacter species was more frequently isolated in the general population. Regarding MDR organisms, Klebsiella species, and Enterobacter species resistant to cefepime, as well as Acinetobacter species resistant to meropenem, were significantly more frequent in transplant patients. CONCLUSION: Antimicrobial resistance is higher, particularly among gram-negative bacteria in the transplant population, although the overall mortality rate between transplant and non-transplant patients with nosocomial BSI is similar.

Comparison of objectively measured and self-reported time spent sitting.

Until recently, methods for objective quantification of sitting time have been lacking. The aim of this study was to validate self-reported measures against objectively measured total sitting time and longest continuous time with uninterrupted sitting during working hours, leisure time on workdays and leisuredays. Objective diurnal measurement of sitting time was obtained among 26 office workers with 2 accelerometers (ActiGraph GT3X+) for a 7-day period. Customized software (Acti4) was used to identify sitting time separated from other sedentary behaviours. Self-reported sitting time was obtained from a retrospective 7-day questionnaire. A generalized linear model showed the difference between the methods. No significant correlations were found between objective and self-reported sitting time (r<0.315). Total sitting time was significantly underestimated (2.4 h) on a leisureday (p<0.001) and uninterrupted sitting time was in all 3 time settings significantly overestimated (0.4-0.5 h) (p<0.045). Poor agreement (mean difference between 0.5 to -2.4 h) between objectively measured and self-reported sitting time was shown in Bland-Altman plots with wide (3.3-10.8 h) limits of agreement. This study showed a great individual variation and a general lack of agreement between self-reported vs. objectively measured total and uninterrupted sitting time. Objective measures are recommended for determining sitting time.

Systemic immunosuppression by methylprednisolone and pregnancy rates in goats undergoing the transfer of cloned embryos.

The presence of the zona pellucida has been perceived as a requirement for the oviductal transfer of cloned embryos at early stages of development while protecting the embryo from an immune system response. We hypothesized that steroid hormone therapy could reduce a potential cellular immune response after the transfer of zona-free cloned embryos into the oviduct of recipient female goats. In Experiment 1, seven does were used to study the systemic immunosuppressant effect of the methylprednisolone administration (for 3 days) on blood cell counts. Whole blood was collected prior to treatment with methyprednisolone and then on Days 1, 2, 3, 4, 7, 14, 21 and 28 after the first dose of methylprednisolone for the analysis of haematological parameters. Methylprednisolone treatment significantly reduced circulating white blood cells and neutrophils in comparison with pre-treatment levels, demonstrating a systemic immunosuppressant effect. In Experiment 2, a group of 58 does were used as recipient females to study the effect of administration of methylprednisolone for 3 days on the establishment of pregnancies after the transfer of zona-free cloned embryos into the oviducts. No effects on pregnancy rates on Day 30 were observed regarding the distinct treatment groups (control vs. methylprednisolone), the source of oocytes (in vivo- vs in vitro-matured) or the presence or absence of the zona pellucida in embryos. In summary, methylprednisolone was effective at inducing a systemic immunosuppressed state in goats, but the treatment prior to embryo transfer did not affect pregnancy rates. Moreover, pregnancy rates were similar between zona-free and zona-intact goat cloned embryos.

Adult polyglucosan body disease - Management and evolution in an intensive rehabilitation program.

Adult polyglucosan body disease is a rare neuromuscular genetic disorder. It is characterized by accumulation of an abnormal structural form of glycogen, particularly in central and peripheral nervous system and muscles. Functional impairments and the rehabilitation approach of this entity is rarely reported. We present a case of a 65-year-old female with several years of undiagnosed symptoms. One year after the diagnosis, the patient was evaluated for the first time in a physical and rehabilitation consultation. We describe the inpatient rehabilitation program - an approach planned to achieve high levels of treatment intensity and with intervention of a multiprofessional and multidisciplinary team.

A Brazilian regional basic diet-induced chronic malnutrition drives liver inflammation with higher ApoA-I activity in C57BL6J mice.

Malnutrition is still considered endemic in many developing countries. Malnutrition-enteric infections may cause lasting deleterious effects on lipid metabolism, especially in children living in poor settings. The regional basic diet (RBD), produced to mimic the Brazilian northeastern dietary characteristics (rich in carbohydrate and low in protein) has been used in experimental malnutrition models, but few studies have explored the effect of chronic RBD on liver function, a central organ involved in cholesterol metabolism. This study aimed to investigate whether RBD leads to liver inflammatory changes and altered reverse cholesterol metabolism in C57BL6/J mice compared to the control group, receiving a standard chow diet. To evaluate liver inflammation, ionized calcium-binding adapter protein-1 (IBA-1) positive cell counting, interleukin (IL)-1ß immunohistochemistry, and tumor necrosis factor (TNF)-α and IL-10 transcription levels were analyzed. In addition, we assessed reverse cholesterol transport by measuring liver apolipoprotein (Apo)E, ApoA-I, and lecithin-cholesterol acyltransferase (LCAT) by RT-PCR. Furthermore, serum alanine aminotransferase (ALT) was measured to assess liver function. RBD markedly impaired body weight gain compared with the control group (P<0.05). Higher hepatic TNF-α (P<0.0001) and IL-10 (P=0.001) mRNA levels were found in RBD-challenged mice, although without detectable non-alcoholic fatty liver disease. Marked IBA-1 immunolabeling and increased number of positive-IBA-1 cells were found in the undernourished group. No statistical difference in serum ALT was found. There was also a significant increase in ApoA mRNA expression in the undernourished group, but not ApoE and LCAT, compared with the control. Altogether our findings suggested that chronic RBD-induced malnutrition leads to liver inflammation with increased ApoA-I activity.

Intermittent preventive treatment of malaria in infants: how does it work and where will it work?

We discuss the potential public health impact of IPTi by estimating the cases of malaria, anaemia and hospital admissions likely to be averted in different transmission settings; and we review the mechanism of action, choice of drugs regimens, and the effect on immunity of IPTi. IPTi using an efficacious drug is likely to substantially reduce cases of clinical malaria in moderate to high transmission settings. However, geographical heterogeneity in malaria transmission could hamper rolling out IPTi as a national policy.

Influence of mother nutrition during pregnancy and/or lactation on offspring food preference in experimental models.

INTRODUCTION: Understanding associations between food preferences and maternal nutrition during pregnancy and lactation could inform efforts to understanding the obesity mechanisms and provide insight to prevent it. Objective: To identify studies that investigated the effects of nutritional interventions during the pregnancy and lactation on the food preferences of offspring. Method: The review was conducted with search for articles in the databases: Scopus, Pubmed, Medline, LILACS, Scielo and Science Direct. Exclusion criteria were used: reviews, human studies, studies with drugs or other substances not related to food. Results: At the end of the search in the databases, 176 references were found. After use the exclusion criteria, reading the titles, abstracts and full articles, were selected 11 articles to compose the review. Conclusion: The selected studies suggested that unbalanced nutrition in early life alters the food preference and neural components related to the consumption of fatty and sugary foods in offspring rodents.

Equity and child-survival strategies.

Recent advances in child survival have often been at the expense of increasing inequity. Successive interventions are applied to the same population sectors, while the same children in other sectors consistently miss out, leading to a trend towards increasing inequity in child survival. This is particularly important in the case of pneumonia, the leading cause of child death, which is closely linked to poverty and malnutrition, and for which effective community-based case management is more difficult to achieve than for other causes of child death. The key strategies for the prevention of childhood pneumonia are case management, mainly through Integrated Management of Childhood Illness (IMCI), and immunization, particularly the newer vaccines against Haemophilus influenzae type b (Hib) and pneumococcus. There is a tendency to introduce both interventions into communities that already have access to basic health care and preventive services, thereby increasing the relative disadvantage experienced by those children without such access. Both strategies can be implemented in such a way as to decrease rather than increase inequity. It is important to monitor equity when introducing child-survival interventions. Economic poverty, as measured by analyses based on wealth quintiles, is an important determinant of inequity in health outcomes but in some settings other factors may be of greater importance. Geography and ethnicity can both lead to failed access to health care, and therefore inequity in child survival. Poorly functioning health facilities are also of major importance. Countries need to be aware of the main determinants of inequity in their communities so that measures can be taken to ensure that IMCI, new vaccine implementation and other child-survival strategies are introduced in an equitable manner.

Hypothyroidism is associated with increased myostatin expression in rats.

Besides its key role in the regulation of muscle growth during development, myostatin also appears to be involved in muscle homeostasis in adults, and its expression is upregulated during muscle atrophy. Since muscle physiology is greatly influenced by thyroid status, and the myostatin promoter region contains several putative thyroid hormone response elements, in the present study we examined the possible role of thyroid hormones in the regulation of myostatin gene expression. Adult male rats were made either hypothyroid or hyperthyroid by means of administration of 0.1% amino- triazole (AMT) in drinking water for 4 weeks, or daily injections of Levo-T4 (L-T4) (100 microg/rat) for 3 weeks, respectively. At the end of the treatment period, both myostatin mRNA and protein content were increased in AMT-treated rats in relation to control rats. In contrast, no changes in myostatin mRNA levels were detected in L-T4-treated rats. The role of thyroid hormones in the regulation of myostatin expression was also investigated in C2C12 cells in vitro. Treatment of C2C12 cells with thyroid hormones stimulated their differentiation into multinucleated myotubes, but did not induce any change in myostatin mRNA abundance. In all, our findings demonstrate that myostatin expression is increased in hypothyroid rats, thus supporting a possible role for this factor in the pathogenesis of the muscle loss that may occur in hypothyroidism.

Permethrin-treated chaddars and top-sheets: appropriate technology for protection against malaria in Afghanistan and other complex emergencies.

Insecticide-treated mosquito nets (ITN) provide excellent protection against malaria; however, they have a number of shortcomings that are particularly evident in politically unstable countries or countries at war: not everyone at risk can necessarily afford a net, nets may be difficult to obtain or import, nets may not be suitable for migrants or refugees sleeping under tents or plastic shelter. There is a need to develop cheaper, locally appropriate alternatives for the most impoverished and for victims of complex emergencies. Afghan women, in common with many Muslim peoples of Asia, wear a veil or wrap known as a chaddar to cover the head and upper body. This cloth doubles as a sheet at night, when they are used by both sexes. A randomized controlled trial was undertaken in which 10% of the families of an Afghan refugee camp (population 3950) in north-western Pakistan had their chaddars and top-sheets treated with permethrin insecticide at a dosage of 1 g/m2 while a further 10% had their chaddars treated with placebo formulation. Malaria episodes were recorded by passive case detection at the camp's health centre. From August to November the odds of having a falciparum or vivax malaria episode were reduced by 64% in children aged 0-10 years and by 38% in refugees aged < 20 years in the group using permethrin-treated chaddars and top-sheets. Incidence in refugees over 20 years of age was not significantly reduced. The cost of the permethrin treatment per person protected (US$0.17) was similar to that for treating bednets (and cost only 10-20% of the price of a new bednet). An entomological study simulating real-life conditions indicated that host-seeking mosquitoes were up to 70% less successful at feeding on men sleeping under treated chaddars and some were killed by the insecticide. Permethrin-treated top-sheets and blankets should provide appropriate and effective protection from malaria in complex emergencies. In Islamic and non-Islamic countries in Asia, treated chaddars and top-sheets should offer a satisfactory solution for the most vulnerable who cannot afford treated nets.

Farmacopuntura utilizando os acupontos Hou Hai e Bai Hui em protocolos de sincronização de estro em cabras / Pharmacopuncture using acupoints Hou Hai and Bai Hui in estrous synchronization protocols in goats

Avaliou-se a eficiência da administração de subdoses de eCG nos acupontos Bai Hui e Hou Hai em protocolos de sincronização de estro em cabras. Na primeira etapa, 57 cabras foram distribuídas aleatoriamente em quatro tratamentos: T1- 300UI de eCG intramuscular (IM); T2- 60UI de eCG no acuponto Hou Hai; T3- 60UI de eCG no acuponto Bai Hui e T4- 60UI de eCG IM; e na segunda etapa, 28 cabras foram distribuídas aleatoriamente em três tratamentos: T1- 300UI de eCG IM; T2- 30UI de eCG no acuponto Bai Hui e T3- 30UI de eCG IM. Ao final do tratamento hormonal, as cabras foram monitoradas para detecção do estro, realização das coberturas e avaliação do comportamento reprodutivo. Os dados foram submetidos à análise de normalidade, seguida dos testes estatísticos adequados para cada variável. Na primeira etapa experimental, obteve-se maior duração de estro nas cabras do T1 (P=0,009). Na segunda etapa experimental, obteve-se maior número de animais em estros no T1 (P=0,03). As demais variáveis para ambas as etapas não sofreram influência dos tratamentos (P>0,05), demonstrando que a administração de subdoses de eCG nos acupontos Bai Hui e Hou Hai foi eficiente para sincronizar o estro.(AU)

The efficiency of administration of subdoses of eCG in the Bai Hui and Hou Hai acupoints in oestrus synchronization protocols in goats was evaluated. In the first stage, 57 goats were randomly assigned to four treatments: T1- 300UI of intramuscular eCG (IM); T2- 60UI of eCG in acupoint Hou Hai; T3- 60UI of eCG in the Bai Hui acupoint and T4- 60UI of eCG IM; and in the second stage, 28 goats were randomly assigned to three treatments: T1-300UI of eCG IM; T2-30UI of eCG in the Bai Hui acupoint and T3- 30UI of eCG IM. At the end of the hormonal treatment the goats were monitored for estrus detection, and evaluation of reproductive behavior. The data were submitted to normality analysis, followed by appropriate statistical tests for each variable. In the first experimental stage, a longer duration of estrus in the T1 goats (P= 0.009) was obtained. In the second experimental stage, a greater number of animals were obtained in estrus at T1 (P= 0.03). The other variables for both experiments were not influenced by the treatments (P> 0.05), demonstrating that administration of eCG subdoses in the Bai Hui and Hou Hai acupoints was efficient to synchronize the estrus.(AU)

Spreading of chronic pain between body regions: prospective cohort study among health care workers.

OBJECTIVE: To estimate the prognostic value of pain in one body region on the risk for developing chronic pain in other body regions. METHODS: Prospective cohort study among 5052 Danish female health care workers responding to a baseline and follow-up questionnaire in 2005 and 2006, respectively. Using adjusted logistic regression analysis, the risk for developing chronic pain (>30 days last year) at follow-up in the low back (among those without low back pain during the last year at baseline) when experiencing sub-chronic (1-30 days last year) or chronic pain in other body regions (i.e., the neck/shoulders and/or the knees at baseline) was modelled. Similar risks were modelled for developing chronic pain in the neck/shoulders and knees. RESULTS: Chronic pain in the neck/shoulders (OR 3.14; 95% CI 1.74-5.70) or knees (OR 2.57; 95% CI 1.28-5.16) at baseline increased the risk for developing chronic pain in the low back at follow-up. Likewise, chronic pain in the neck/shoulders (OR 2.39; 95% CI 1.36-4.17) or low back (OR 1.82 95%; CI 1.07-3.09) at baseline increased the risk for developing chronic pain in the knees at follow-up. The risk for developing chronic neck/shoulder pain was not significantly increased when having pain in the low back or knees at baseline. CONCLUSION: Among health care workers, chronic musculoskeletal pain in one body region increases the risk for developing chronic pain in other pain-free body regions. Prevention of musculoskeletal disorders among health care workers should focus holistically on the musculoskeletal system.
