The impact of climate change on airborne and droplet-borne diseases and hospital response measures.

OBJECTIVES: This review synthesizes quantitative evidence on how climate change modulates airborne and droplet-borne disease transmission an … disaster models are insufficient. Resilience requires a paradigm shift toward "climate-integrated" infection control. Critical strategies include integrating meteorological data into predictive surveillance systems and using ventilation, upper-room UVGI, and portable air cleaning as complementary engineering controls.

The HIV reservoir landscape in elite controllers.

PURPOSE OF REVIEW: In this review, we intend to define the main characteristics of the elite controller reservoir, exploring into its heterogeneity, which goes hand in hand with the different progression phenotypes within elite controllers. RECENT FINDINGS: Show that the viral reservoir measured by high-resolution techniques in elite controllers is heterogeneous, exhibiting distinct characteristics in elite controllers who ultimately lose control compared to those with persistent viral remission. Among the latter, we find exceptional individuals with a reservoir consistent with a phenomenon o

Risk of serious infection with JAK inhibitors in immune-mediated inflammatory skin diseases: a meta-analysis of randomized clinical trials.

BACKGROUND: Emerging research suggests that Janus kinase-signal transducer and activator of transcription (JAK-STAT) inhibitors may be associated with a higher risk of serious infection for patients with rheumatoid arthritis. However, there is no consensus on whether JAK inhibitors increase the risk of serious infection in patients with Immune-mediated inflammatory skin diseases (IMISDs). OBJECTIVES: To ascertain the correlation between JAK inhibitor use and the risk of serious infection in patients with IMISDs. METHODS: PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and r

Хирургическая помощь в эпоху Mpox Clade I: Обзор и призыв к обеспечению готовности.

В июле 2022 года вирус Mpox, ранее известный как Monkeypox, был объявлен "Public Health Emergency of International Conference" из-за его быстрого глобального распространения. К 2024 году более вирулентный и фатальный вариант Clade Ib достиг США. В то время как Mpox, как правило, представляет собой самоограниченную сыпь, все более распространенными становятся серьезные проявления, требующие хирургического вмешательства, что требует повышения осведомленности и готовности хирургов. В нем излагаются основные больничные протоколы и меры предосторожности для смягчения носокомиального распространения

Following the eradication of smallpox, intermittent small outbreaks of mpox (monkeypox) have occurred with increasing frequency, primarily i … e mpox virus, clinical presentation, complications, approach to diagnosis, methods of transmission, infection control recommendations, indications for vaccination, and therapeutic options to inform dermatologists on the frontline of the mpox epidemic.

Collaborative Study to Establish National Reference Standards for Anti-HIV-1 Antibody.

BACKGROUND: National reference standards for anti-HIV-1 antibody are needed to evaluate the performance and maintain the quality control of anti-HIV-1 antibody assays. The aim of this study was to prepare a mixed-titer performance panel and assess its suitability as a national reference standard for anti-HIV-1 antibody according to stability, collaboration, and other studies. METHODS: Nineteen serum samples from different HIV patients were obtained, along with 15 units of fresh frozen plasma samples with negative anti-HIV-1 antibody results. Ten anti-HIV-1 antibody-positive candidate standard

Blastocystis Subtypes and Culture Characteristics of Isolates from Human Stools Related with the Presence of Gastrointestinal Symptoms: A Case-Control Study.

PURPOSE: To stablish if Blastocystis subtypes influences gastrointestinal symptoms. METHODS: Case-control study. We obtained sequencing for Blastocysts subtyping from 13 patients with gastrointestinal symptoms (diarrhea or abdominal pain) and 12 from individuals without symptoms. RESULTS: 12 sequences were from Subtype 2 and one from Subtype 3 in symptomatic individuals and nine samples were from Subtype 1, one from Subtype 2, and two from Subtype 3 in asymptomatic individuals. The prevalence of subtype 2 in symptomatic individuals was vastly different compared to the frequency in asymptomat

Recognition of aerosol transmission of infectious agents: a commentary.

Although short-range large-droplet transmission is possible for most respiratory infectious agents, deciding on whether the same agent is also airborne has a potentially huge impact on the types (and costs) of infection control interventions that are required.The concept and definition of aerosols is also discussed, as is the concept of large droplet transmission, and airborne transmission which is meant by most authors to be synonymous with aerosol transmission, although some use the term to mean either large droplet or aerosol transmission.However, these terms are often used confusingly when…

Biological control of plant pathogens by Bacillus species.

Bacteria from the Bacillus group are microorganisms that inhabit a large number of different habitats. They are well known as producers of a wide array of antagonistic compounds of different structures, having between 5 to 8% of the total genome devoted to biosynthesis of secondary metabolites. Most important bioactive molecules from the genus Bacillus are non-ribosomally synthesized peptides and lipopeptides, polyketide compounds, bacteriocins and siderophores. Lipopeptides from Bacillus have very complex mechanisms of biosynthesis catalyzed by non-ribosomal peptide synthetases (NRPSs), large

The case for low temperature sterilization.

How do healthcare facilities meet the conflicting demands of togher infection control guidelines and regulations and increasingly delicate hi-tech medical devises? Faster, more effective, low temperature sterilization is a big part of the answer, says Dean Burand, Divisional Regulatory Affairs manager at specialist in instrument decontamination and sterilization, IHSS.

Conjunctival flora of clinically normal and diseased turtles and tortoises.

BACKGROUND: In captive breed turtles and tortoises conjunctival disease is common. Our aim was to investigate the bacterial and fungal flora present in the eyes of healthy and pathological chelonians and to compare findings in turtles with those in tortoises. RESULTS: Samples were taken from the conjunctival sacs of 34, diseased and healthy, chelonians (18 tortoises and 16 turtles) and submitted to bacterial and fungal investigation. All samples showed bacterial growth. Thirteen animals (38%), harboured a single bacterial species as sole isolate and twenty-one animals (62%) harboured more tha

Основы прионов и их активация (обзор).

Прион — инфекционная частица, состоящая из аномальной изоформы прионного белка (PrPSc) и вызывающая такие прионские заболевания, как энцефалопатия говядины (BSE), болезнь Креуцфельда-Якоба (CJD) и скрепи. Принимающие клетки выражают клеточный прионный белок (PrPC), который играет роль в обычных функциях, таких как антиокисляющий стресс. PrPSc получается из ПХП и производится путем преобразования в конформацию. Прион известен как резистентный патоген, который трудно активировать с помощью обычных процедур стерилизации. Поэтому для предупреждения прионовых иатрогенных заболеваний важное значение

[Travelers' vaccines].

The number of Japanese oversea travelers has gradually increased year by year, however they usually pay less attention to the poor physical condition at the voyage place. Many oversea travelers caught vaccine preventable diseases in developing countries. The Vaccine Guideline for Oversea Travelers 2010 published by Japanese Society of Travel Health will be helpful for spreading the knowledge of travelers' vaccine and vaccine preventable diseases in developing countries. Many travelers' vaccines have not licensed in Japan. I hope these travelers' vaccines, such as typhoid vaccine, meningococcal

SARS: here to stay? Monkeypox: beware of exotic pets.

Severe acute respiratory syndrome (SARS) is probably here to stay, and every health care institution should take precautions against an outbreak. The signs and symptoms of SARS are nonspecific, and there is no early diagnostic test, no specific treatment, and no vaccine. In some parts of the world, including Canada, more than 80% of probable cases were nosocomial.
