Biomarkers associated with the development of comorbidities in patients with atopic dermatitis: A systematic review.

Biomarkers associated with the development of comorbidities in atopic dermatitis (AD) patients have been reported, but have not yet been systematically reviewed. Seven electronic databases were searched, from database inception to September 2021. English language randomized controlled trials, prospective and retrospective cohort, and case-control studies that investigated the association between a biomarker and the development of comorbidities in AD patients were included.

Students' use of caffeine, alcohol, dietary supplements, and illegal substances for improving academic performance in a New Zealand university.

This study aimed to describe patterns of use and attitudes towards a broad variety of substances for improving academic performance at a New Zealand university. 685 students (from 1800 invited) completed an online questionnaire (38% response rate). They were asked about their lifetime and current substance use for improving academic performance, as well as their reasons for use, attitudes and perceptions of: caffeine, alcohol, dietary supplements, prescription stimulants, other prescription substances, and illicit substances.

[Lafora disease in a Beagle - diagnosis and therapy].

Lafora disease is an autosomal recessive lysosomal storage disorder leading to an accumulation of toxic glycogen bodies into the cells of the central nervous system and other tissues. In the progressive form of myoclonic epilepsy, clinical signs typically start around 7 years of age. Causal therapy is impossible, however, in the early stages the symptoms may at least be alleviated by modern antiepileptic drugs.

[The Contributions of the East-German Sports Medicine Specialist and Neurologist Bernhard Schwarz (1918-1991) in the Field of Boxing].

This study is the first to provide research on the East-German (GDR) sports physician and neurologist Bernhard Schwarz. It summarises Schwarz's publications from 1953 to 1966 regarding the impact of boxing on health, particularly craniocerebral injury. Also, the study analyses his work in the context of current discussions.

[From boxing to geriatric psychiatry : Facets from the work of East German social psychiatrist Bernhard Schwarz (1918-1991)].

For the first time, this study presents publications representative for the work of the neurologist and sports physician Bernhard Schwarz, whose career spans from the 1950s to the 1970s. His work is characterized by exceptional originality. Schwarz acted as the physician of the GDR national boxing team and conducted a systematic long-term study of 800 boxers.

What should an ideal vaccine postlicensure safety system be?

In 2007 the National Vaccine Program, along with the Centers for Disease Control and Prevention, the Food and Drug Administration, the National Institutes of Health, and the Health Resources and Services Administration, sponsored a public conference titled "Vaccine Safety Evaluation: Post Marketing Surveillance." The objective was to discuss enhanced approaches to postlicensure evaluation of vaccine safety, including active and passive surveillance systems and special studies. The conference participants reviewed the evolution of the assessment of vaccine safety, detailed current national approaches to postmarketing safety, and offered new approaches to evaluating vaccine safety.

Soluble tetraarylporphyrin-platinum conjugates as cytotoxic and phototoxic antitumor agents.

A series of asymmetric tetraarylporphyrins was synthesized from pyrrole, para-substituted oligo- or poly(ethylene glycol) monomethyl ether benzaldehyde and from 4-hydroxybenzaldehyde etherified with diethyl bromomalonate according to the Lindsey method. After hydrolysis of the tetraarylporphyrin esters, the resulting carboxylic acid groups were used to bind platinum fragments. In comparison to analogous hematoporphyrin-platinum conjugates, the title compounds are characterized by a 30 nm bathochromic shift of their absorption bands.

Hematoporphyrin-derived soluble porphyrin-platinum conjugates with combined cytotoxic and phototoxic antitumor activity.

To combine the cytotoxic activity of cisplatin and the phototoxicicity of hematoporphyrin derivatives in the same molecule, hematoporphyrin was derivatized at the two secondary alcohol positions by etherification with oligo- and poly(ethylene glycol) units. The two carboxylic acid groups of the propionate side chains were used to bind platinum fragments. The antiproliferative activity of 35 platinum complexes (0.

Global eradication of poliomyelitis: benefit-cost analysis.

A benefit-cost analysis of the Poliomyelitis Eradication Initiative was undertaken to facilitate national and international decision-making with regard to financial support. The base case examined the net costs and benefits during the period 1986-2040; the model assumed differential costs for oral poliovirus vaccine (OPV) and vaccine delivery in industrialized and developing countries, and ignored all benefits aside from reductions in direct costs for treatment and rehabilitation. The model showed that the "break-even" point at which benefits exceeded costs was the year 2007, with a saving of US$ 13 600 million by the year 2040.

Vaccine-preventable disease and immunization in the developing world.

Vaccines have given health care providers control over a substantial portion of the morbidity and mortality in the developing world. Global efforts have immunized two-thirds of the world's children with DTP and polio vaccines; 72% have received BCG and 59% measles vaccine; but only 29% of pregnant women have received two doses of tetanus toxoid. In addition, vaccines against yellow fever, Japanese encephalitis, hepatitis B, rubella, and mumps and meningococcal polysaccharide vaccine are being used in specific regions of the world.

Vaccine-associated paralytic poliomyelitis. United States: 1973 through 1984.

From 1973 through 1984, there were 138 cases of paralytic poliomyelitis reported in the United States; 105 (76%) were vaccine associated. Of the 105 vaccine-associated cases, 35 occurred in recipients of oral polio vaccine (OPV), 50 in contacts to OPV recipients, 14 in immune deficient individuals, and six in individuals who had no history of receiving OPV or contact with recent OPV recipients. Thirty-three (94%) of the recipient cases, 41 (82%) of the contact cases, and five (36%) of the immune deficient cases were associated with the first dose of OPV.

Prevalence of rubella antibodies in Massachusetts schoolchildren.

In 1982, 1,871 (79%) of 2,368 eligible 6th, 10th and 12th grade students in Massachusetts participated in a statewide serosurvey for rubella antibodies. Sera were screened at the Centers for Disease Control (CDC) by a reference hemagglutination inhibition assay at 1:8, equivalent to approximately 15 International Units (IU)/ml. Sera negative by the CDC hemagglutination inhibition assay were retested using an enzyme immunoassay, a passive hemagglutination assay, and a commercial hemagglutination inhibition test.

Pertussis epidemic in Oklahoma. Difficulties in preventing transmission.

From Jan 1 to Dec 31, 1983, 351 cases of pertussis were reported in Oklahoma. Overall, 59% of the cases were among children 3 months to 6 years of age, the target age group for pertussis vaccination; only 42% of the patients in this age group were appropriately immunized for age with diphtheria and tetanus toxoids and pertussis vaccine (DTP). A survey of 185 households in the neighborhoods of three cases found that only 65% of 57 children 3 months to 6 years of age were appropriately immunized for their age.

Transmission of measles in medical settings. 1980 through 1984.

For the five-year period 1980 through 1984, a total of 241 persons with measles in 30 states were identified as probably having acquired their infection in a medical facility. The proportion of all measles cases acquired in medical settings increased from 0.7% for 1980 through 1982 to 2.

Nifedipine reversibly arrests mitosis in stamen hair cells of tradescantia.

Mitotic stamen hair cells of Tradescantia virginiana (cv. Zwanenburg Blue) become arrested in metaphase following a 30-min treatment with 10 to 100 microM nifedipine, a Ca2+-channel entry blocker. The time interval between nuclear envelope breakdown and anaphase onset in untreated cells is approximately 33 min +/- 4 min; nifedipine extends this "metaphase transit time" beyond 70 min.

Immunity against measles and rubella in Massachusetts schoolchildren.

A statewide serosurvey was conducted among 6th, 10th and 12th grade Massachusetts schoolchildren in 1982. Sera were screened using a standard measles hemagglutination inhibition (HI) assay, a sensitive measles plaque neutralization assay, and four rubella assays with corresponding sensitivity limits of approximately 15, 10, 7.5, and 5 international units (IU) of rubella antibody/ml respectively.

Appropriate age for measles vaccination in the United States.

The appropriate age for measles vaccination is determined by weighing the risk of measles disease and complications at a given age with vaccine efficacy at that age. In the United States, measles vaccine was initially used in children as young as 9 months of age because the disease was common and complications were greatest in persons less than 1 year of age. In 1965, when it became apparent that vaccine failure was unacceptably high in children less than 1 year and when epidemiologic analysis indicated that children greater than or equal to 1 year, particularly schoolchildren, were the primary focus of measles transmission, the vaccination age was raised to 12 months.

The virtual elimination of rubella and mumps from the United States and the use of combined measles, mumps and rubella vaccines (MMR) to eliminate measles.

The measles elimination effort, which began in 1978, has made dramatic contributions to the virtual elimination of rubella and congenital rubella syndrome (CRS) and the control of mumps in the USA. The use of combined MMR vaccine has resulted in immunization levels at school entry in excess of 95% against each of these diseases. As a result, record low levels of rubella, CRS, and mumps were reported in 1984.

The buffering of calcium with quin2 reversibly forestalls anaphase onset in stamen hair cells of Tradescantia.

Cells from immature stamen hairs of the spiderwort plant Tradescantia virginiana cv. Zwanenburg Blue exhibit remarkable precision in the timing of their mitotic events: anaphase onset occurs 33 +/- 4 min after nuclear envelope breakdown, and cell plate vesicle aggregation occurs approximately 19 +/- 4 min after anaphase onset. To test the hypothesis that altered calcium levels might affect mitotic events, we incubated stamen hairs with the acetoxymethyl ester of the Ca-chelator, quin2 (quin2AM), or the K+-salt of quin2 free acid, and found that mitotic progression was blocked in metaphase and late anaphase.
