Treatment of infection and inflammation associated with COVID-19, multi-drug resistant pneumonia and fungal sinusitis by nebulizing a nanosilver solution.

Solutions containing Ag0 nanoclusters, Ag+1, and higher oxidation state silver, generated from nanocrystalline silver dressings, were anti-inflammatory against porcine skin inflammation. The dressings have clinically-demonstrated broad-spectrum antimicrobial activity, suggesting application of nanosilver solutions in treating pulmonary infection. Nanosilver solutions were tested for antimicrobial efficacy; against HSV-1 and SARS-CoV-2; and nebulized in rats with acute pneumonia. Patients with pneumonia (ventilated), fungal sinusitis, burns plus COVID-19, and two non-hospitalized patients with COVID-19 received nebulized nanosilver solution. Nanosilver solutions demonstrated pH-dependent antimicrobial efficacy; reduced infection and inflammation without evidence of lung toxicity in the rat model; and inactivated HSV-1 and SARS-CoV-2. Pneumonia patients had rapidly reduced pulmonary symptoms, recovering pre-illness respiratory function. Fungal sinusitis-related inflammation decreased immediately with infection clearance within 21 days. Non-hospitalized patients with COVID-19 experienced rapid symptom remission. Nanosilver solutions, due to anti-inflammatory, antiviral, and antimicrobial activity, may be effective for treating respiratory inflammation and infections caused by viruses and/or microbes.

Livestock and livelihoods of smallholder cattle-owning households in Cambodia: the contribution of on-farm and off-farm activities to income and food security.

The majority of smallholder farming households in Cambodia are rurally based and rely on agriculture to support their livelihoods. However, in recent years, growth in the agriculture sector has stagnated with farmers facing several challenges including declining prices for traditional crops and irregular rainfall patterns. This has led to a need for farmers to diversify income sources with livestock promoted as a more viable livelihood activity, particularly the raising of cattle and poultry. However, uncertain profitability of livestock activities is a common perception by smallholders, especially where animals have not been traditionally viewed as a primary income source. To address this, information is required which compares the income and expenses associated with livestock raising to other on-farm activities and off-farm sources. This study reports on a survey of livelihood survey of 17 male and 21 female representatives of 20 households owning cattle in Cambodia, comparing the associated income and expenses of the various livelihood activities in the 12-month period from January to December 2016. Combined total household income from both on-farm and off-farm sources ranged from USD875 to 17730 with an average of USD6779, representing 51% and 49% from on-farm and off-farm activities, respectively. Cattle raising was the most common source of on-farm income (85%), contributing USD1064 and representing 22% of total household income. General household expenses, such as food and transportation (including expenses associated with off-farm employment), represented the majority of total household expenses (79%). Gross profit calculations indicated higher values for pig raising (USD1841.79), cattle (USD950.80) and non-rice crops (USD884) whilst the highest gross margin value was recorded for cattle (89.33%) followed by vegetables (85.27%) and non-rice crops (83.08%). Whilst wet season and dry season rice returned a negative gross profit value of USD197.27 and USD90.60 on average per household, respectively, both were ranked as most important for household consumption, followed by poultry, providing the main source of energy (rice) and protein (chicken meat) and sustaining household food requirements. The study concludes that although smallholder cattle-owning households in Cambodia undertake a diverse range of on-farm activities, as cattle raising provides a superior income source due to higher returns and lower variable costs, it could be promoted as a preferred livelihood activity by agencies conducting rural extension activities. Although consideration of available labour and monetary funds to invest in cattle raising is required, it was observed that income from off-farm sources may prove beneficial in providing the additional monetary funds to support cattle-raising activities and assist in providing generally poor smallholder households with enhanced economic resilience.

Functional and oncological outcomes of robot-assisted radical prostatectomy in obese men: a matched-pair analysis.

Robot-assisted radical prostatectomy (RARP) in men with body mass index (BMI) ≥ 35 kg/m2 is considered technically challenging. We conducted a retrospective matched-pair analysis to compare the oncological and functional outcomes of RARP in men with BMI ≥ 35 kg/m2. We interrogated our prospectively maintained RARP database and identified 1273 men who underwent RARP from January 2018 till June 2021. Among them, 43 had BMI ≥ 35 kg/m2, and 1230 had BMI < 35 kg/m2. A 1:1 genetic matching was performed between these two groups for PSA, Gleason grades, clinical stage, D'Amico risk stratification, and nerve-spare extent. Continence rates and biochemical rates on 1-year follow-up were analysed. We performed statistical analysis using SPSS, and Paired tests were done using Wilcoxon sign rank-sum test. p < 0.05 was considered statistically significant. The two groups were comparable in almost all parameters except for age. Console time (p = 0.20) and estimated blood loss (p > 0.90) were not significantly different. There was no blood transfusion, open conversion or (Clavien-Dindo grade ≥ 3) intra/postoperative complication in either of the two groups. The two groups did not have any difference in biochemical recurrence rates (BCR) on 1-year follow-up (p > 0.90). Men with BMI ≥ 35 achieved continence rates equivalent to men with BMI < 35 within 1 year. On logistic regression analysis, age (p < 0.001) and extent of nerve sparing (p = 0.026) emerged as significant factors influencing continence recovery. RARP is safe in men with BMI ≥ 35 kg/m2. The 1-year continence and oncological outcomes are similar to matched men with BMI < 35 kg/m2 undergoing RARP.

Design and operation of the National Survey of Early Childhood Health, 2000.

OBJECTIVES: This report presents the development, plan, and operation of the National Survey of Early Childhood Health, a module of the State and Local Area Integrated Telephone Survey, conducted by the National Center for Health Statistics, Centers for Disease Control and Prevention. This survey was designed to assess parents' perceptions of their children's pediatric care. In addition, data were collected that can be used to examine relationships between the promotion of health in the pediatric office and promotion of health in the home. Funding for the survey was provided by The Gerber Foundation, the American Academy of Pediatrics, and the Maternal and Child Health Bureau, Health Resources and Services Administration. The UCLA Center for Healthier Children, Families, and Communities contributed to the design of the study and the questionnaire. METHODS: A national random-digit-dialed (RDD) sample of households with children 4-35 months of age was selected. The study included an oversample of households having an eligible black non-Hispanic or Hispanic child. In households with more than one eligible child, one was randomly selected to be the subject of the interview. The respondent was the parent or guardian who was most responsible for the child's health care. A computer-assisted telephone interviewing (CATI) system was used to collect the data. RESULTS: A total of 2,068 interviews were completed during the first half of 2000. The response rate was 65.6%. A data file has been released that contains demographic information on the focal child and respondent, substantive health and health-related data, and sampling weights. Estimates based on the sampling weights generalize to the entire U.S. population of children 4-35 months of age.
