    The objectives of this study were to determine the movement of a virus throughout a household and the impact of an alcohol-based hand sanitizer (ABHS) on reducing the movement and exposure of the virus to household members. Bacterial virus MS-2 was used as the surrogate for human enteric and respiratory viruses. Seven households with families having at least two children in the age range of 2-18 living in the home were used in this study. The hands of one adult family member were contaminated with 1 × 10(8). MS-2 bacteriophage in each home. After 8 h, the hands of each family member (10 fingers) and 20 frequently touched fomites were sampled to determine baseline contamination without intervention. Within 8 h, MS-2 was detected on all of the family member's hands and most of the fomites. The intervention consisted of providing the families in all selected homes with bottles of an ABHS, which were placed in the kitchen, bathrooms, and nurseries. Smaller individual bottles were provided for each family member greater than 12 years old to place in purses, pockets, backpacks, etc. The families were instructed to use the ABHS one time or three times during the day. For one and three uses, a statistically significant reduction of virus on un-inoculated and inoculated hands of ~99% occurred within 8 h. Similar reductions occurred on fomites throughout the households (97-99%). These results demonstrate that the use of an ABHS can significantly reduce transfer of a virus to the hands, and to the commonly touched surfaces within the household. PMID:24728950

    Norovirus is the leading cause of food-related illness in the United States, and contamination of ready-to-eat items by food handlers poses a high risk for disease. This study reports the in vitro (suspension test) and in vivo (fingerpad protocol) assessments of a new ethanol-based hand sanitizer containing a synergistic blend of polyquaternium polymer and organic acid, which is active against viruses of public health importance, including norovirus. When tested in suspension, the test product reduced the infectivity of the nonenveloped viruses human rotavirus (HRV), poliovirus type 1 (PV-1), and the human norovirus (HNV) surrogates feline calicivirus (FCV) F-9 and murine norovirus type 1 (MNV-1) by greater than 3 log(10) after a 30-s exposure. In contrast, a benchmark alcohol-based hand sanitizer reduced only HRV by greater than 3 log(10) and none of the additional viruses by greater than 1.2 log(10) after the same exposure. In fingerpad experiments, the test product produced a 2.48 log(10) reduction of MNV-1 after a 30-s exposure, whereas a 75% ethanol control produced a 0.91 log(10) reduction. Additionally, the test product reduced the infectivity titers of adenovirus type 5 (ADV-5) and HRV by > or =3.16 log(10) and > or =4.32 log(10), respectively, by the fingerpad assay within 15 s; and PV-1 was reduced by 2.98 log(10) in 30 s by the same method. Based on these results, we conclude that this new ethanol-based hand sanitizer is a promising option for reducing the transmission of enteric viruses, including norovirus, by food handlers and care providers.

In contrast, a benchmark alcohol-based hand sanitizer reduced only HRV by greater than 3 log10 and none of the additional viruses by greater than 1.2 log10 after the same exposure. In fingerpad experiments, the test product produced a 2.48 log10 reduction of MNV-1 after a 30-s exposure, whereas a 75% ethanol control produced a 0.91 log10 reduction. Additionally, the test product reduced the infectivity titers of adenovirus type 5 (ADV-5) and HRV by ≥3.16 log10 and ≥4.32 log10, respectively, by the fingerpad assay within 15 s; and PV-1 was reduced by 2.98 log10 in 30 s by the same method. Based on these results, we conclude that this new ethanol-based hand sanitizer is a promising option for reducing the transmission of enteric viruses, including norovirus, by food handlers and care providers.

    Effective hand hygiene is essential to prevent the spread of pathogens on produce farms and reduce foodborne illness. The U.S. Food and Drug Administration Food Safety Modernization Act Proposed Rule for Produce Safety recommends the use of soap and running water for hand hygiene of produce handlers. The use of alcohol-based hand sanitizer (ABHS) may be an effective alternative hygiene intervention where access to water is limited. There are no published data on the efficacy of either soap or ABHS-based interventions to reduce microbial contamination in agricultural settings. The goal of this study was to assess the ability of two soap-based (traditional or pumice) and two ABHS-based (label-use or two-step) hygiene interventions to reduce microbes (coliforms, Escherichia coli, and Enterococcus spp.) and soil (absorbance of hand rinsate at 600 nm [A600]) on farmworker hands after harvesting produce, compared with the results for a no-hand-hygiene control. With no hand hygiene, farmworker hands were soiled (median A600, 0.48) and had high concentrations of coliforms (geometric mean, 3.4 log CFU per hand) and Enterococcus spp. (geometric mean, 5.3 log CFU per hand) after 1 to 2 h of harvesting tomatoes. Differences in microbial loads in comparison to the loads in the control group varied by indicator organism and hygiene intervention (0 to 2.3 log CFU per hand). All interventions yielded lower concentrations of Enterococcus spp. and E. coli (P < 0.05), but not of coliforms, than were found in the control group. The two-step ABHS intervention led to significantly lower concentrations of coliforms and Enterococcus spp. than the pumice soap and label-use ABHS interventions (P < 0.05) and was the only intervention to yield significantly fewer samples with E. coli than were found in the control group (P < 0.05). All interventions removed soil from hands (P < 0.05), soap-based interventions more so than ABHS-based interventions (P < 0.05). ABHS-based interventions were

    Three ethanol-based sanitizers were compared with three antimicrobial liquid soaps for their efficacy to inactivate polio-, adeno-, vaccinia- and bovine viral diarrhoea virus (BVDV) as well as feline calicivirus (FCV) and murine norovirus (MNV) as surrogates for human norovirus in a suspension test. Additionally, sanitizers and soaps were examined against MNV in a modified fingerpad method. All sanitizers sufficiently inactivated the test viruses in the suspension test whereas two soaps were active only against vaccinia virus and BVDV. In the modified fingerpad test a povidone-iodine-containing soap was superior to the sanitizers whereas the other two soaps showed no activity. PMID:23009803

    We investigated the virucidal activity of commercially available alcohol-based hand rub products against coxsackievirus A7, B5, feline calicivirus F9, and human adenovirus type 3, type 7, type 8 using susceptible cell lines, Vero cells, CRFK cells, and A549 cells. Fifteen tested hand rub products were ethanol (EtOH) for disinfection (Japanese Pharmacopoeia Grade), two EtOH-based products, one povidone iode-containing product, one alkyldiaminoethylglycine hydrochloride-containing product, six benzalkonium chloride (BAK)-containing products, and four chlorohexidine gluconate (CHG)-containing products. Some active ingredients (BAK, benzetonium chloride, and CHG) were diluted with EtOH to make 0.5% and 0.2% solutions. Virus inactivation rates were calculated after contact with each hand rub product for 10 or 60 seconds. Of the hand rub products tested, only the povidone iode-based product showed antiviral activity superior to that of EtOH against all the strains. EtOH solutions of active ingredients (0.2% and 0.5%) also showed decreased antiviral activity. In conclusion, antiviral activity of all the commercially available alcohol-based hand rub products except that containing povidone idode was dependent on their active ingredients. The povidone idode-containing hand rub product kept its effectiveness even after the dilution with EtOH. Although alcohol-based hand rub products are convenient and suitable for the control of some microbes, they are not generally recommended for the control of viral infections. PMID:22451431

    The emergence of alcohol-based hand cleansers may represent an alternative to soap and water in the clinical dental setting. In this study, the antimicrobial efficacy of traditional hand washing vs. a unique alcohol-based hand cleanser with persistence was evaluated. Two experienced dentists participated over a 10-day period. On days 1-5, each clinician used an antibacterial liquid soap (Dial, Dial Corporation, Scottsdale, AZ). Days 6-10, an alcohol-based hand cleanser (Triseptin Water Optional, Healthpoint Surgical, Fort Worth, TX) was used. Sampling was by modified glove juice technique. The results indicate that the alcohol-based hand cleanser dramatically outperforms the traditional hand washing agent in the general dental setting. PMID:20131613

    Catching crew members can heavily contaminate their hands with organic material. They can act as mechanical vector and spread diseases between farms. Hand hygiene is an important issue for the industry as a whole and for human health by reducing contamination risks. Many studies, in human medicine, tend to make hand rub a standard for hand hygiene. However, few studies have tested the effectiveness of hand hygiene products on visibly contaminated hands. The objective of this study was to evaluate the effectiveness of practical hand sanitization protocols: water and soap, degreasing cream and hand wipes, all combined with alcohol-based hand gel. The use of alcohol-based gel alone was also evaluated. For the reduction of coliforms after washing, there was no statistically significant difference between protocols when the initial level of bacterial contamination was low to moderate. When hands were highly contaminated, the alcohol-based gel alone was less effective than the degreasing cream combined with the alcohol-based gel (p=0.002). As for the reduction in total aerobic bacteria counts, there was no difference between protocols when the initial level of bacterial contamination was low. The water, soap and alcohol-based gel protocol was more effective than the scrubbing wipes and alcohol-based gel protocol when hands were moderately (p=0.002) and highly contaminated (p=0.001). All protocols were effective in neutralizing Salmonella on hands. Reducing the level of bacterial contamination on hands before using an alcohol-based gel seems important to ensure effective hand sanitation for highly and moderately contaminated hands. This can be done by using a degreasing cream or water and soap. Based on the survey, catching crew members preferred using warm water and soap compared to a degreasing cream. PMID:23618466

    Disinfection is an essential measure for interrupting human norovirus (HuNoV) transmission, but it is difficult to evaluate the efficacy of disinfectants due to the absence of a practicable cell culture system for these viruses. The purpose of this study was to screen sodium hypochlorite and ethanol for efficacy against Norwalk virus (NV) and expand the studies to evaluate the efficacy of antibacterial liquid soap and alcohol-based hand sanitizer for the inactivation of NV on human finger pads. Samples were tested by real-time reverse transcription-quantitative PCR (RT-qPCR) both with and without a prior RNase treatment. In suspension assay, sodium hypochlorite concentrations of >or=160 ppm effectively eliminated RT-qPCR detection signal, while ethanol, regardless of concentration, was relatively ineffective, giving at most a 0.5 log(10) reduction in genomic copies of NV cDNA. Using the American Society for Testing and Materials (ASTM) standard finger pad method and a modification thereof (with rubbing), we observed the greatest reduction in genomic copies of NV cDNA with the antibacterial liquid soap treatment (0.67 to 1.20 log(10) reduction) and water rinse only (0.58 to 1.58 log(10) reduction). The alcohol-based hand sanitizer was relatively ineffective, reducing the genomic copies of NV cDNA by only 0.14 to 0.34 log(10) compared to baseline. Although the concentrations of genomic copies of NV cDNA were consistently lower on finger pad eluates pretreated with RNase compared to those without prior RNase treatment, these differences were not statistically significant. Despite the promise of alcohol-based sanitizers for the control of pathogen transmission, they may be relatively ineffective against the HuNoV, reinforcing the need to develop and evaluate new products against this important group of viruses.

    Recently, the procedure for surgical hand hygiene has been switching to a two-stage method and hand-rubbing method from the traditional hand-scrubbing method. Both the two-stage and hand-rubbing methods use alcohol-based hand-rubbing after hand washing. The former requires 5 min of antiseptic hand washing, and the latter 1 min of nonantiseptic hand washing. For a prolonged bactericidal effect in terms of surgical hand hygiene, chlorhexidine gluconate (CHG) has been noted due to its residual activity. However, no detailed study comparing the disinfection efficacy and prolonged effects according to different contents of CHG and the usage of alcohol-based hand-rubbing has been conducted. The glove juice method is able to evaluate disinfection efficacy and prolonged effects of the disinfectants more accurately because it can collect not only transitory bacteria but also normal inhabitants on hands. In the present study, we examined the disinfection efficacy and prolonged effects on alcohol-based hand-rubbing containing CHG by six hand-rubbing methods and three two-stage methods using the glove juice method. In both methods, 3 mL (one pump dispenser push volume) alcohol-based hand-rubbing solution containing 1% (w/v) CHG showed the highest disinfection efficacy and prolonged effects, and no significant difference was found between the hand-rubbing and two-stage methods. In the two methods of hand hygiene, the hand-rubbing method was able to save time and cost. Therefore, the data strongly suggest that the hand-rubbing method using a one pump dispenser push volume of alcohol-based hand-rubbing solution containing 1% (w/v) CHG is suitable for surgical hand hygiene.

    Hands can be a vector for transmitting pathogenic microorganisms to foodstuffs and drinks, and to the mouths of susceptible hosts. Hand washing is the primary barrier to prevent transmission of enteric pathogens via cross-contamination from infected persons. Conventional hand washing involves the use of water, soap, and friction to remove dirt and microorganisms. The availability of hand sanitizing products for use when water and soap are unavailable has increased in recent years. The aim of this systematic review was to collate scientific information on the efficacy of hand sanitizers compared with washing hands with soap and water for the removal of foodborne pathogens from the hands of food handlers. An extensive literature search was carried out using three electronic databases: Web of Science, Scopus, and PubMed. Twenty-eight scientific publications were ultimately included in the review. Analysis of this literature revealed various limitations in the scientific information owing to the absence of a standardized protocol for evaluating the efficacy of hand products and variation in experimental conditions. However, despite conflicting results, scientific evidence seems to support the historical skepticism about the use of waterless hand sanitizers in food preparation settings. Water and soap appear to be more effective than waterless products for removal of soil and microorganisms from hands. Alcohol-based products achieve rapid and effective inactivation of various bacteria, but their efficacy is generally lower against nonenveloped viruses. The presence of food debris significantly affects the microbial inactivation rate of hand sanitizers. PMID:27296611

    Background: It is proved that surgical hand disinfectant contains alcohol, and has favorable properties such as strong and rapid antibacterial effect, ease of application, and suitable effect on skin. Therefore, nowadays use of them has been gradually replacing traditional surgical hand scrub with antibacterial soap. Hence, several domestic and imported products are available to the healthcare facilities in Iran. This study was done in order to determine the antibacterial effect of Decosept, Sterillium, and Septicidine on skin flora. Materials and Methods: This clinical trial was carried out on 20 volunteers. Subjects disinfected their hands with three test products. At first, subjects washed their hands with soap. Then pre-value sample was taken from the finger tips in Tryptic Soy Broth (TSB).1 After that, the hands were disinfected with one of the surgical hand rubs with as much volume as necessary to keep the hands wet, at the recommended application time. Immediate post-value sample was taken from one hand and the other hand was gloved for 3 h. After removing the surgical glove, 3 h post-value sample (sustained effect) was taken from the hand. Results: All products remarkably decreased the colony forming units (CFU) immediately (P < 0.0001) and 3 h (P < 0.0001) after disinfection. Analysis of variance (ANOVA) revealed significant differences among immediate post-values (P < 0.005). Septicidine was significantly the least effective than the others, whereas 3 h effect of the three products was similar (P = 0.630, ANOVA). Conclusions: Our results confirm the effectiveness of the three alcohol-based hand rubs. Considering the short application time, less volume used, and more antibacterial effect, however, Sterillium seems to be a better choice. PMID:25878700

    Hand disinfection with alcohols-based hand rubs (ABHRs) are known to be the most effective measure to prevent nosocomial infections in healthcare. ABHRs contain on average 70% by weight of one or more alcohols. During the hand rubbing procedure, users are exposed to these alcohols not only through dermal contact, but also via inhalation, due to the physical and chemical properties of alcohols volatilizing from alcoholic solutions or gels into the air. Ethanol ingestion is well known to increase risks of several diseases (affecting the pancreas, liver, cardiovascular system…), but there is a lack of knowledge about the effects of exposure to other alcohols (including n- or isopropanol) via inhalation and dermal contact, despite the worldwide use of ABHRs. This work aims at discussing possible health effects related to unintentional alcoholization (via inhalation and dermal contact) from professional ABHR usage to suggest the need for more research in this area (but not to question the value of ABHRs). Based upon an average of 30 hand rubbings per healthcare professional per day, it can be assumed that a healthcare worker may be exposed to a maximum 5,500 mg/m(3) per work shift, five times above the recommended occupational time weighted average limit. Thus, in order to answer the question posed in the title, studies on spatial and temporal variability of alcohol emission from ABHRs in real world situations and studies on certain high risk individuals are needed.

    Purpose: The aim of this study was to evaluate the overall risk of hand disinfectants and skin antiseptics to become contaminated with bacterial spores throughout the production process and the subsequent in-use period, hence posing a public health risk. Methods: Microbiological assessment of primary packaging material was carried out and long-term survival of bacterial spores in alcohol was assessed using sporulated B. subtilis ATCC 6633 as a standard. In-use contamination of alcohol-based formulations was tested by repeated use over 12 months under practical conditions and microbiological and physico-chemical data were determined. Results: Among 625 containers analyzed, 542 did not yield any microbial growth. Median colony count for aerobic spore-forming bacteria was 0.2 cfu/10 ml container content. No anaerobic spore-forming bacteria were detected. Additionally, long-term survival of bacterial spores in aliphatic C2–C3 alcohols revealed 1-propanol to reduce the number of spores most effectively, with 2-propanol and ethanol having a somewhat less pronounced impact. In-use tests did not detect any microbial contamination or change in the physicochemical properties of the tested products over 12 months. Conclusions: Our data reveals that state-of-the-art production processes of alcohol-based hand rubs and antiseptics can be regarded safe. Primary packaging material and use were not found to pose a significant contamination risk as far as bacterial spores are concerned. Based on the data from this study, a microbial limit of <1 cfu/10 ml can be suggested as a quality-control threshold for finished goods to ensure high quality and safe products. PMID:24327945

    Hand hygiene is considered to be the most effective way of preventing microbial transmission and healthcare-associated infections. The use of alcohol-based hand rubs (AHRs) is the reference standard for effective hand hygiene. AHR consumption is a valuable surrogate parameter for hand hygiene performance, and it can be easily tracked in the healthcare setting. AHR availability at the point of care ensures access to optimal agents, and makes hand hygiene easier by overcoming barriers such as lack of AHRs or inconvenient dispenser locations. Data on AHR consumption and availability at the point of care in European hospitals were obtained as part of the Prevention of Hospital Infections by Intervention and Training (PROHIBIT) study, a framework 7 project funded by the European Commission. Data on AHR consumption were provided by 232 hospitals, and showed median usage of 21 mL (interquartile range (IQR) 9-37 mL) per patient-day (PD) at the hospital level, 66 mL/PD (IQR 33-103 mL/PD) at the intensive-care unit (ICU) level, and 13 mL/PD (IQR 6-25 mL/PD) at the non-ICU level. Consumption varied by country and hospital type. Most ICUs (86%) had AHRs available at 76-100% of points of care, but only approximately two-thirds (65%) of non-ICUs did. The availability of wall-mounted and bed-mounted AHR dispensers was significantly associated with AHR consumption in both ICUs and non-ICUs. The data show that further improvement in hand hygiene behaviour is needed in Europe. To what extent factors at the national, hospital and ward levels influence AHR consumption must be explored further. PMID:26417851

    Clinicians who work in the postanesthesia care unit (PACU), operating room (OR), and intensive care unit (ICU) have a greater opportunity to cross-contaminate patients because of high workloads and frequent patient contact events. Much progress has been made to increase hand hygiene compliance with the introduction of alcohol-based wall, bedside, and pocket dispensers. The introduction of body-worn alcohol-based dispensers to anesthesia and ICU providers has been shown to decrease ICU hospital-acquired infections and ventilator-associated pneumonias, and decrease contamination of the anesthesia workplace. Body-worn alcohol-based dispensers are an improvement in ergonomics, especially for those working in high intensity areas. The unit worn on the belt or scrubs waist is readily accessible, can be activated with one hand, and can be a vital tool to close the gap for hand hygiene. PMID:23522268

    Alcohol compounds are increasingly used as a substitute for hand washing in health care environments and some public places because these compounds are easy to use and do not require water or hand drying materials. However, the effectiveness of these compounds depends on how much soil (bioburden) is present on the hands. Workers in health care environments and other public places must wash their hands before using antiseptics and/or wearing gloves. However, alcohol-based antiseptics, also called rubs and sanitizers, can be very effective for rapidly destroying some pathogens by the action of the aqueous alcohol solution without the need for water or drying with towels. Alcohol-based compounds seem to be the most effective treatment against gram-negative bacteria on lightly soiled hands, but antimicrobial soaps are as good or better when hands are more heavily contaminated. Instant sanitizers have no residual effect, unlike some antimicrobial soaps that retain antimicrobial activity after the hygienic action has been completed, e.g., after hand washing. Many alcohol-based hand rubs have antimicrobial agents added to them, but each formulation must be evaluated against the target pathogens in the environment of concern before being considered for use. Wipes also are widely used for quick cleanups of hands, other body parts, and surfaces. These wipes often contain alcohol and/or antimicrobial compounds and are used for personal hygiene where water is limited. However, antiseptics and wipes are not panaceas for every situation and are less effective in the presence of more than a light soil load and against most enteric viruses. PMID:21219730

    This prospective clinical study evaluates the effectiveness of an alcohol-based hand rub (Avagard™) for pre-surgical hand antisepsis in an equine hospital and compares it with traditional scrubbing technique using 4% chlorhexidine gluconate sponges and water. Prior to elective surgery, 3 board-certified surgeons were randomly assigned to hand antisepsis with either technique. Culture samples of each hand were taken at 4 times: before and after neutral soap hand wash, after scrub or rubbing technique, and after surgery. There was no significant difference in mean bacterial colony forming units between scrub and rub techniques over the 3 time periods (P = 0.6), controlling for initial counts. One horse from the scrub group had a skin incision infection following stifle arthroscopy; this was resolved with medical treatment. The alcohol-based hand rub is equivalent in efficacy for pre-surgical hand antisepsis to traditional water-based scrubs in an equine hospital setting. PMID:26834268

    Enteric protozoan parasites, which are spread by the fecal-oral route, are important causes of diarrhea (Giardia duodenalis) and amebic dysentery (Entamoeba histolytica). Cyst walls of Giardia and Entamoeba have a single layer composed of fibrils of β-1,3-linked GalNAc and β-1,4-linked GlcNAc (chitin), respectively. The goal here was to determine whether hand sanitizers that contain ethanol or isopropanol as the active microbicide might reduce transmission of these parasites. We found that treatment with these alcohols with or without drying in a rotary evaporator (to model rapid evaporation of sanitizers on hands) kills 85 to 100% of cysts of G. duodenalis and 90 to 100% of cysts of Entamoeba invadens (a nonpathogenic model for E. histolytica), as shown by nuclear labeling with propidium iodide and failure to excyst in vitro. Alcohols with or without drying collapsed the cyst walls of Giardia but did not collapse the cyst walls of Entamoeba. To validate the in vitro results, we showed that treatment with alcohols eliminated oral infection of gerbils by 1,000 G. duodenalis cysts, while a commercial hand sanitizer (Purell) killed E. invadens cysts that were directly applied to the hands. These results suggest that expanded use of alcohol-based hand sanitizers might reduce the transmission of Giardia and Entamoeba. PMID:26282413

    The aims of this study were to compare the antibacterial efficacy of handrubbing with an alcoholic rinse (AHRR) and two different alcoholic gels (AHRG) in reducing hand contamination under practical use conditions. We wanted to assess the acceptability of the three products and to determine the effect of each product on overall hand hygiene compliance. A prospective alternating time-series clinical trial was performed in a medical intensive care unit. The study was divided into three six-week periods (P1, P2, P3). Handrubbing was achieved with Sterillium rinse (AHRR) during P1, sterillium gel(AHRG-1) during P2 and Manugel Plus (AHRG-2) during P3. Pre- and post-rubbing hand contaminations were assessed immediately after a direct contact with a patient, using the glove juice technique. Health care workers (HCWs) evaluated the acceptability of the products through a self-administered anonymous questionnaire. Compliance of HCWs with hand hygiene was assessed during the three periods. We studied 242 handrubbing opportunities. The mean reduction factor (expressed as the Log(10) CFU/mL) of the AHRR, AHRG-1 and AHRG-2 were 1.28+/-0.95, 1.29+/-0.84 and 0.51+/-0.73, respectively (p<0.001). Assessment of the three products by HCWs indicated that AHRR and AHRG-1 were significantly better accepted than AHRG-2. The overall compliance of HCWs to hand hygiene was better when gel was available. Under practical use conditions, AHRG-1 and AHRR were more effective than AHRG-2, although all were claimed to pass the European standard EN1500. In vivo trials are essential to compare the antimicrobial efficacy of products for handrubbing. PMID:17513011

    Healthcare workers are required to disinfect the hands several times a day using hand disinfectants, which leads to chronic hand exposure to high levels of antimicrobials contained in the disinfectants, which could compromise the skin integrity. This problem may be addressed by developing hand disinfectants containing synergistic combinations of small amounts of antimicrobials and other agents. The synergistic effect of farnesol and essential oils with several antimicrobials was studied in vitro to select an effective antimicrobial system in preservative concentration for use in healthcare hand rub. Farnesol and lemon oil showed synergistic activity against S. aureus, in combination with benzalkonium chloride and benzethonium chloride, but not with other antimicrobials studied. All essential oils studied showed synergy with benzethonium chloride against Staphylococcus aureus and Escherichia coli. An alcohol-based healthcare hand rub (ZBF hand rub) containing this unique synergistic combination of farnesol and benzethonium chloride was then developed and its efficacy as a healthcare hand rub was evaluated in human volunteers according to the US FDA-TFM protocol using Serratia marcescens as a marker organism. The ZBF hand rub showed a 3.22 log(10) reduction in the microbial count after the first application and a 5.49 log(10) reduction after the tenth application in vivo and exceeds the US FDA-TFM criteria for healthcare hand rub. The ZBF hand rub did not irritate the hands when tested on human volunteers when applied 10 times everyday for five consecutive days. The ZBF hand rub exhibits more than 5.5 log(10) reduction in the microbial count within 15s and more than 2.8 log(10) reduction in the two types of viruses tested within 30s in vitro. When evaluated in an in vitro pig skin model, the ZBF hand rub shows better prolonged activity (20-35 min post-application) against transient bacteria (S. aureus and E. coli) compared to other alcohol-based hand rubs.

    This study evaluated the efficacy of aqueous (aQUAT) and isopropyl alcohol-based quaternary ammonium (ipQUAT) sanitizers for reducing Salmonella spp., Escherichia coli O157:H7, or Listeria monocytogenes populations on peanut and pistachio shell pieces. Inoculated nutshells were mixed with QUAT sanitizers, water, or 70% ethanol and enumerated immediately or after incubation at 30 °C for 48 h. None of the treatments had any immediate effect on Salmonella or E. coli O157:H7 populations on the peanut or pistachio shells. L. monocytogenes populations declined immediately on the peanut and pistachio shells treated with aQUAT or ipQUAT. After incubation, Salmonella and E. coli O157:H7 populations increased significantly on the water- or aQUAT-treated peanut and pistachio shells. L. monocytogenes populations also increased significantly on the water- or aQUAT-treated peanut shells, but levels did not change on the water-treated pistachio shells and levels were just above the limit of detection on the aQUAT-treated pistachio shells. After treatment with ipQUAT and 48-h incubation, Salmonella and E. coli O157:H7 populations decreased to or below the limit of detection on both shell types; L. monocytogenes populations remained at or below the limit of detection on both shell types.

    This study assessed the inhaled dose of alcohol during hand disinfection. Experiments were conducted with two types of hand rub using two hand disinfection procedures. Air samples were collected every 10 s from the breathing zone, by bubbling through a mixture of K2Cr2O7 and H2SO4. The reduction of dichromate ions in the presence of alcohols was followed by UV-vis spectrophotometry. The difference in intensity of the dichromate absorption peak was used to quantify the alcohol concentration expressed in ethanol equivalent. During hygienic hand disinfection, the mean ethanol equivalent concentrations peaked at around 20–30 s for both hand rubs (14.3 ± 1.4 mg/L for hand rub 1 and 13.2 ± 0.7 mg/L for hand rub 2). During surgical hand disinfection, two peaks were found at the same time (40 and 80 s) for both hand rubs. The highest mean concentrations were 20.2 ± 0.9 mg/L for hand rub 1 and 18.1 ± 0.9 mg/L for hand rub 2. For hand rub 1, the total absorbed doses, calculated from ethanol with an inhalation flow of 24 L/min and an absorption rate of 62%, were 46.5 mg after one hygienic hand disinfection and 203.9 mg after one surgical hand disinfection. Although the use of ABHRs leads to the absorption of very low doses, sudden, repeated inhalation of high alcohol concentrations raises the question of possible adverse health effects. PMID:22690169

    Recent studies have shown that hydro-alcoholic solutions are more efficient than traditional medicated soaps in the pre-surgical hand antisepsis of human surgeons but there is little veterinary literature on the subject. The aim of this study was to compare the efficiency of medicated soaps and a hydro-alcoholic solution prior to surgery using an in-use testing method in a veterinary setting. A preliminary trial was performed that compared the mean log(10) number of bacterial colony forming units (CFU) and the reduction factors (RF) between two 5-min hand-scrubbing sessions using different soaps, namely, povidone iodine (PVP) and chlorhexidine gluconate (CHX), and the 1.5-min application of a hydro-alcoholic rub. A clinical in-use trial was then used to compare the hydro-alcoholic rub and CHX in a surgical setting. Sampling was performed using finger printing on agar plates. The hydro-alcoholic rub and CHX had a similar immediate effect, although the sustained effect was significantly better for the hydro-alcoholic rub, while PVP had a significantly lower immediate and sustained effect. The hydro-alcoholic rub showed good efficiency in the clinical trial and could be considered as a useful alternative method for veterinary surgical hand antisepsis. PMID:21316990

    A 2005 survey showed that there are at least four legal product classifications for hand disinfectants in the European Union: medicinal products, biocidal products, cosmetics and medical devices. An internationally harmonized classification does not exist. The regulatory status of those products is defined at national level. In order to assure compliance with the regulations these four classifications provide different levels of official surveillance varying from product-specific marketing authorisations and production site audits to the obligation to just work in accordance with certain general guidelines. Biocidal product regulations cover eco-toxicological and toxicological aspects, but do not very much address to the customers' quality and efficacy expectations. In contrast, the medicinal product legislation is the most ambitious one claiming quality, safety, efficacy, and an independent benefit risk-assessment by an authority. In respect of ambition, the two remaining product categories--cosmetics and medical devices--rank between the both classifications mentioned above. For medical devices, it is the responsibility of the manufacturer to make sure the products meet defined essential requirements regarding quality, safety and performance and to have an appropriate quality assurance system implemented under third party control. For cosmetics there are some legal restrictions, but within these it is the sole responsibility of the manufacturer to ensure that the products are safe and fulfil their claims. This paper describes one way out of this increasingly complex situation, the definition of a single quality standard meeting the users' expectations as well as all legal requirements regardless of the specific sales country. This international quality standard for products would take priority over any individual national standard, to the benefit of users. PMID:18994682

    Background Laboratory-based evidence is lacking regarding the efficacy of non-pharmaceutical interventions such as alcohol-based hand sanitizer and respiratory hygiene to reduce the spread of influenza. Methods The Pittsburgh Influenza Prevention Project was a cluster-randomized trial conducted in ten Pittsburgh, PA elementary schools during the 2007-2008 influenza season. Children in five intervention schools received training in hand and respiratory hygiene, and were provided and encouraged to use hand sanitizer regularly. Children in five schools acted as controls. Children with influenza-like illness were tested for influenza A and B by RT-PCR. Results 3360 children participated. Using RT-PCR, 54 cases of influenza A and 50 cases of influenza B were detected. We found no significant effect of the intervention on the primary study outcome of all laboratory confirmed influenza cases (IRR 0.81 95% CI 0.54, 1.23). However, we did find statistically significant differences in protocol-specified ancillary outcomes. Children in intervention schools had significantly fewer laboratory-confirmed influenza A infections than children in control schools, with an adjusted IRR of 0.48 (95% CI 0.26, 0.87). Total absent episodes were also significantly lower among the intervention group than among the control group; adjusted IRR 0.74 (95% CI 0.56, 0.97). Conclusions Non-pharmaceutical interventions (respiratory hygiene education and the regular use of hand sanitizer) did not reduce total laboratory confirmed influenza. However the interventions did reduce school total absence episodes by 26% and laboratory-confirmed influenza A infections by 52%. Our results suggest that NPIs can be an important adjunct to influenza vaccination programs to reduce the number of influenza A infections among children. PMID:21691245

    Hand washing is the most effective way to prevent the spread of communicable disease. The purpose of this double-blind, placebo-controlled study was to assess whether an alcohol-free, instant hand sanitizer containing surfactants, allantoin, and benzalkonium chloride could reduce illness absenteeism in a population of 769 elementary school children and serve as an effective alternative when regular soap and water hand washing was not readily available. Prior to the study, students were educated about proper hand washing technique, the importance of hand washing to prevent transmission of germs, and the relationship between germs and illnesses. Children in kindergarten through the 6th grade (ages 5-12) were assigned to the active or placebo hand-sanitizer product and instructed to use the product at scheduled times during the day and as needed after coughing or sneezing. Data on illness absenteeism were tracked. After 5 weeks, students using the active product were 33% less likely to have been absent because of illness when compared with the placebo group.

    2007-01-01

    Background A procedure for including activity against enveloped viruses in the post-contamination treatment of hands has been recommended, but so far no European standard is available to implement it. In 2004, the German Robert Koch-Institute (RKI) and the German Association for the Control of Virus Disease (DVV) suggested that vaccinia virus and bovine viral diarrhea virus (BVDV) should be used as test viruses in a quantitative suspension test to determine the activity of a disinfectant against all enveloped viruses. Methods We have studied the activities of three commonly-used alcohol-based hand rubs (hand rub A, based on 45% propan-2-ol, 30% propan-1-ol and 0.2% mecetronium etilsulfate; hand rub B, based on 80% ethanol; hand rub C, based on 95% ethanol) against vaccinia virus and BVDV, and in addition against four other clinically relevant enveloped viruses: herpes simplex virus (HSV) types 1 and 2, and human and avian influenza A virus. The hand rubs were challenged with different organic loads at exposure time of 15, 30 and 60 s. According to the guidelines of both BGA/RKI and DVV, and EN 14476:2005, the reduction of infectivity of each test virus was measured on appropriate cell lines using a quantitative suspension test. Results All three alcohol-based hand rubs reduced the infectivity of vaccinia virus and BVDV by ≥ 4 log10-steps within 15 s, irrespective of the type of organic load. Similar reductions of infectivity were seen against the other four enveloped viruses within 15 s in the presence of different types of organic load. Conclusion Commonly used alcohol-based hand rubs with a total alcohol concentration ≥ 75% can be assumed to be active against clinically relevant enveloped viruses if they effectively reduce the infectivities of vaccinia virus and BVDV in a quantitative suspension test.

    The use of alcohol-based hand rubs serves to reduce hospital-acquired infections. Many products of this type are now on offer and it is essential to know how to rank their efficacy. A sequence of tests is proposed here to compare any given new alcohol-based solution against the reference solution (60% 2-isopropyl-alcohol) with 30 s of contact time: (i) in vitro (with pig skin as carrier) testing of >30 species of microorganism; (ii) in vitro assessment of residual efficacy (after 30 min of drying); (iii) in vivo study of transient microbiota (modification of the EN 1500 standard procedure) using four ATCC strains; (iv) in vivo study of resident hand microbiota. After performing the in vitro evaluation of seven alcohol-based hand rubs, the two most efficacious (chlorhexidine-quac-alcohol and mecetronium- alcohol) were chosen and studied, comparatively with the reference solution (60% isopropyl alcohol), in vitro (for chemical sustainability on the skin) and in vivo (against transient and resident microbiota). Chlorhexidine-quac-alcohol proved to be significantly superior to mecetronium-alcohol or the reference solution in all tests, except against resident microbiota for which the improvement was not statistically significant.

    This study was undertaken to determine differences in microflora on the nails of health care workers (HCWs) wearing artificial nails compared with control HCWs with native nails and to assess the effect on these microflora of hand cleansing with antimicrobial soap or alcohol-based gel. Cultures were obtained from 21 HCWs wearing artificial nails and 20 control HCWs before and after using antimicrobial soap or alcohol-based gel. Before cleansing with soap, 86% of HCWs with artificial nails had a pathogen (gram-negative bacilli, Staphylococcus aureus, or yeasts) isolated, compared with 35% of controls (P=.003); a similar difference was noted before hand cleansing with gel (68% vs. 28%; P=.03). Significantly more HCWs with artificial nails than controls had pathogens remaining after hand cleansing with soap or gel. Of HCWs with artificial nails, only 11% cleared pathogens with soap compared with 38% with gel. Of control HCWs, only 14% cleared with soap compared with 80% with gel. Artificial acrylic fingernails could contribute to the transmission of pathogens, and their use by HCWs should be discouraged. PMID:11170943

    Background The economical impact of absenteeism and reduced productivity due to acute infectious respiratory and gastrointestinal disease is normally not in the focus of surveillance systems and may therefore be underestimated. However, large community studies in Europe and USA have shown that communicable diseases have a great impact on morbidity and lead to millions of lost days at work, school and university each year. Hand disinfection is acknowledged as key element for infection control, but its effect in open, work place settings is unclear. Methods Our study involved a prospective, controlled, intervention-control group design to assess the epidemiological and economical impact of alcohol-based hand disinfectants use at work place. Volunteers in public administrations in the municipality of the city of Greifswald were randomized in two groups. Participants in the intervention group were provided with alcoholic hand disinfection, the control group was unchanged. Respiratory and gastrointestinal symptoms and days of work were recorded based on a monthly questionnaire over one year. On the whole, 1230 person months were evaluated. Results Hand disinfection reduced the number of episodes of illness for the majority of the registered symptoms. This effect became statistically significant for common cold (OR = 0.35 [0.17 - 0.71], p = 0.003), fever (OR = 0.38 [0.14-0.99], p = 0.035) and coughing (OR = 0.45 [0.22 - 0.91], p = 0.02). Participants in the intervention group reported less days ill for most symptoms assessed, e.g. colds (2.07 vs. 2.78%, p = 0.008), fever (0.25 vs. 0.31%, p = 0.037) and cough (1.85 vs. 2.00%, p = 0.024). For diarrhoea, the odds ratio for being absent became statistically significant too (0.11 (CI 0.01 - 0.93). Conclusion Hand disinfection can easily be introduced and maintained outside clinical settings as part of the daily hand hygiene. Therefore it appears as an interesting, cost-efficient method within the scope of company health

    The aim of this study is to increase hand sanitizer usage among healthcare workers by developing and implementing a low-cost intervention using RFID and wireless mesh networks to provide real-time alarms for increasing hand hygiene compliance during opportune moments in an open layout Intensive Care Unit (ICU). A wireless, RFID based system was developed and implemented in the ICU. The ICU beds were divded into an intervention arm (n = 10) and a control arm (n = 14). Passive RFID tags were issued to the doctors, nurses and support staff of the ICU. Long range RFID readers were positioned strategically. Sensors were placed beneath the hand sanitizers to record sanitizer usage. The system would alert the HCWs by flashing a light if an opportune moment for hand sanitization was detected. A significant increase in hand sanitizer use was noted in the intervention arm. Usage was highest during the early part of the workday and decreased as the day progressed. Hand wash events per person hour was highest among the ancilliary staff followed by the doctors and nurses. Real-time feedback has potential to increase hand hygiene compliance among HCWs. The system demonstrates the possibility of automating compliance monitoring in an ICU with an open layout. PMID:25957165

    Aim It is our opinion that the CDC and the WHO have underestimated cross-contamination under examination gloves in dental clinics while wearing jewelry, such as finger rings. These agencies only “recommend” removing jewelry, and only washing hands for 15 seconds with soap and warm water before donning gloves. This study examined several washing procedures and finger rings using simulated microbes. Methodology A gloved rubber hand manikin was made and fitted with a fresh disposable vinyl glove. Four fingers were fitted with rings or no ring, dusted with simulated microbes, and washed with a scrub brush for 5, 15, and 25 seconds under 20°C and 40°C water alone, or with liquid hand soap. Light levels (in lux) of fluorescent powder before and after washing were measured and delta scores calculated for changes in light levels, equivalent to effectiveness of hand washing procedures. A full-factorial, 3-factor analysis of variance (ANOVA) was used to test for differences among levels of the three study factors—time, temperature, and soap use. Tukey's post hoc honestly significant difference (HSD) test was applied to significant factors to examine pair-wise differences between factor levels. Results It was found that the longer the hands with rings were washed with a scrub brush under flowing water, the more simulated microbes were removed. By 25 seconds, all methods were essentially the same. Simulated microbes were more difficult to remove from the palm compared to the back of the hand. The liquid hand soap used in this study was more effective with warm water than cold. When given a choice of washing with cold water up to 15 seconds, it would be preferable not to use soap to remove simulated microbes. Qualitatively, the outer surface of finger rings were more effectively cleaned than the crevice below the ring, and the ring with a stone setting appeared to accumulate and retain simulated microbes more than other rings. Conclusion The most effective treatment was

    Norovirus (NoV) epidemics normally peak in December in Japan; however, the peak in the 2009-2010 season was delayed until the fourth week of January 2010. We suspected intensive hand hygiene that was conducted for a previous pandemic influenza in 2009 as the cause of this delay. We analysed the NoV epidemic trend, based on national surveillance data, and its associations with monthly output data for hand hygiene products, including alcohol-based skin antiseptics and hand soap. The delayed peak in the NoV incidence in the 2009-2010 season had the lowest number of recorded cases of the five seasons studied (2006-2007 to 2010-2011). GII.4 was the most commonly occurring genotype. The monthly relative risk of NoV and monthly output of both alcohol-based skin antiseptics and hand soap were significantly and negatively correlated. Our findings suggest an association between hand hygiene using these products and prevention of NoV transmission. PMID:27301793

    The baseline compliance with handwashing in a French university hospital was as low as the compliance rates reported in other countries, i.e., less than 50%. By introducing the use of hand-rubbing with an alcoholic solution, as a substitution method for both handwashing with soap and handwashing with an antiseptic agent, we significantly improved hand-cleansing compliance. Despite these encouraging results, mainly due to the accessibility of these non-aqueous products, three major obstacles remain before a wide acceptance by healthcare workers: distrust in terms of efficacy, distrust in terms of skin tolerance and lack of knowledge on hand-cleansing indications.

    Bisphenol A (BPA) is an endocrine disrupting environmental contaminant used in a wide variety of products, and BPA metabolites are found in almost everyone's urine, suggesting widespread exposure from multiple sources. Regulatory agencies estimate that virtually all BPA exposure is from food and beverage packaging. However, free BPA is applied to the outer layer of thermal receipt paper present in very high (∼20 mg BPA/g paper) quantities as a print developer. Not taken into account when considering thermal paper as a source of BPA exposure is that some commonly used hand sanitizers, as well as other skin care products, contain mixtures of dermal penetration enhancing chemicals that can increase by up to 100 fold the dermal absorption of lipophilic compounds such as BPA. We found that when men and women held thermal receipt paper immediately after using a hand sanitizer with penetration enhancing chemicals, significant free BPA was transferred to their hands and then to French fries that were eaten, and the combination of dermal and oral BPA absorption led to a rapid and dramatic average maximum increase (Cmax) in unconjugated (bioactive) BPA of ∼7 ng/mL in serum and ∼20 µg total BPA/g creatinine in urine within 90 min. The default method used by regulatory agencies to test for hazards posed by chemicals is intra-gastric gavage. For BPA this approach results in less than 1% of the administered dose being bioavailable in blood. It also ignores dermal absorption as well as sublingual absorption in the mouth that both bypass first-pass liver metabolism. The elevated levels of BPA that we observed due to holding thermal paper after using a product containing dermal penetration enhancing chemicals have been related to an increased risk for a wide range of developmental abnormalities as well as diseases in adults.

    Handwashing with soap effectively reduces exposure to diarrhea-causing pathogens. Interventions to improve hygiene and sanitation conditions in schools within low-income countries have gained increased attention; however, their impact on schoolchildren's exposure to fecal pathogens has not been established. Our trial examined whether a school-based water, sanitation, and hygiene intervention reduced Escherichia coli contamination on pupils' hands in western Kenya. A hygiene promotion and water treatment intervention did not reduce risk of E. coli presence (relative risk [RR] = 0.92, 95% confidence interval [CI] = 0.54–1.56); the addition of new latrines to intervention schools significantly increased risk among girls (RR = 2.63, 95% CI = 1.29–5.34), with a non-significant increase among boys (RR = 1.36, 95% CI = 0.74–2.49). Efforts to increase usage of school latrines by constructing new facilities may pose a risk to children in the absence of sufficient hygiene behavior change, daily provision of soap and water, and anal cleansing materials.

    Background In order to fight the spread of the novel H1N1 influenza, health authorities worldwide called for a change in hygiene behavior. Within a longitudinal study, we examined who collected a free bottle of hand sanitizer towards the end of the first swine flu pandemic wave in December 2009. Methods 629 participants took part in a longitudinal study assessing perceived likelihood and severity of an H1N1 infection, and H1N1 influenza related negative affect (i.e., feelings of threat, concern, and worry) at T1 (October 2009, week 43–44) and T2 (December 2009, week 51–52). Importantly, all participants received a voucher for a bottle of hand sanitizer at T2 which could be redeemed in a university office newly established for this occasion at T3 (ranging between 1–4 days after T2). Results Both a sequential longitudinal model (M2) as well as a change score model (M3) showed that greater perceived likelihood and severity at T1 (M2) or changes in perceived likelihood and severity between T1 and T2 (M3) did not directly drive protective behavior (T3), but showed a significant indirect impact on behavior through H1N1 influenza related negative affect. Specifically, increases in perceived likelihood (β = .12), severity (β = .24) and their interaction (β = .13) were associated with a more pronounced change in negative affect (M3). The more threatened, concerned and worried people felt (T2), the more likely they were to redeem the voucher at T3 (OR = 1.20). Conclusions Affective components need to be considered in health behavior models. Perceived likelihood and severity of an influenza infection represent necessary but not sufficient self-referential knowledge for paving the way for preventive behaviors. PMID:21789224

    An occupational physician reported to the French Health Products Safety Agency (Afssaps) a case of adverse effect of acute pancreatitis (AP) in a teaching nurse, after multiple demonstrations with ethanol-based hand sanitizers (EBHSs) used in a classroom with defective mechanical ventilation. It was suggested by the occupational physician that the exposure to ethanol may have produced a significant blood ethanol concentration and subsequently the AP. In order to verify if the confinement situation due to defective mechanical ventilation could increase the systemic exposure to ethanol via inhalation route, a physiologically based pharmacokinetic (PBPK) modeling was used to predict ethanol blood levels. Under the worst case scenario, the simulation by PBPK modeling showed that the maximum blood ethanol concentration which can be predicted of 5.9 mg/l is of the same order of magnitude to endogenous ethanol concentration (mean = 1.1 mg/L; median = 0.4 mg/L; range = 0–35 mg/L) in nondrinker humans (Al-Awadhi et al., 2004). The present study does not support the likelihood that EBHS leads to an increase in systemic ethanol concentration high enough to provoke an acute pancreatitis. PMID:22577377

    Effective handwashing with soap requires reliable access to water supplies. However, more than three billion persons do not have household-level access to piped water. This research addresses the challenge of improving hand hygiene within water-constrained environments. The antimicrobial efficacy of alcohol-based hand sanitizer, a waterless hand hygiene product, was evaluated and compared with handwashing with soap and water in field conditions in Dar es Salaam, Tanzania. Hand sanitizer use by mothers resulted in 0.66 and 0.64 log reductions per hand of Escherichia coli and fecal streptococci, respectively. In comparison, handwashing with soap resulted in 0.50 and 0.25 log reductions per hand of E. coli and fecal streptococci, respectively. Hand sanitizer was significantly better than handwashing with respect to reduction in levels of fecal streptococci (P = 0.01). The feasibility and health impacts of promoting hand sanitizer as an alternative hand hygiene option for water-constrained environments should be assessed. PMID:20134005

    Pathogenic strains of Escherichia coli and human norovirus are the main etiologic agents of foodborne illness resulting from inadequate hand hygiene practices by food service workers. This study was conducted to evaluate the antibacterial and antiviral efficacy of various hand hygiene product regimens under different soil conditions representative of those in food service settings and assess the impact of product formulation on this efficacy. On hands contaminated with chicken broth containing E. coli, representing a moderate soil load, a regimen combining an antimicrobial hand washing product with a 70% ethanol advanced formula (EtOH AF) gel achieved a 5.22-log reduction, whereas a nonantimicrobial hand washing product alone achieved a 3.10log reduction. When hands were heavily soiled from handling ground beef containing E. coli, a wash-sanitize regimen with a 0.5% chloroxylenol antimicrobial hand washing product and the 70% EtOH AF gel achieved a 4.60-log reduction, whereas a wash-sanitize regimen with a 62% EtOH foam achieved a 4.11-log reduction. Sanitizing with the 70% EtOH AF gel alone was more effective than hand washing with a nonantimicrobial product for reducing murine norovirus (MNV), a surrogate for human norovirus, with 2.60- and 1.79-log reductions, respectively. When combined with hand washing, the 70% EtOH AF gel produced a 3.19-log reduction against MNV. A regimen using the SaniTwice protocol with the 70% EtOH AF gel produced a 4.04-log reduction against MNV. These data suggest that although the process of hand washing helped to remove pathogens from the hands, use of a wash-sanitize regimen was even more effective for reducing organisms. Use of a high-efficacy sanitizer as part of a wash-sanitize regimen further increased the efficacy of the regimen. The use of a well-formulated alcohol-based hand rub as part of a wash-sanitize regimen should be considered as a means to reduce risk of infection transmission in food service facilities. PMID

    Background Viral upper respiratory infections have been implicated as a major cause of asthma exacerbations among school age children. Regular hand washing is the most effective method to prevent the spread of viral respiratory infections but, effective hand washing practices are difficult to establish in schools. Objectives This randomized controlled trial evaluated whether a standardized regimen of hand washing plus alcohol-based hand sanitizer could reduce asthma exacerbations more than schools’ usual hand hygiene practices. Methods This was a two year, community-based, randomized controlled crossover trial. Schools were randomized to usual care then intervention (Sequence 1) or intervention then usual care (Sequence 2). Intervention schools were provided with alcohol-based hand sanitizer, hand soap, and hand hygiene education. The primary outcome was the proportion of students experiencing an asthma exacerbation each month. Generalized estimating equations were used to model the difference in the marginal rate of exacerbations between sequences while controlling for individual demographic factors and the correlation within each student and between students within each school. Results 527 students with asthma were enrolled among 31 schools. The hand hygiene intervention did not reduce the number of asthma exacerbations as compared to the schools’ usual hand hygiene practices (p=0.132). There was a strong temporal trend as both sequences experienced fewer exacerbations during Year 2 as compared to Year 1 (p<0.001). Conclusions While the intervention was not found to be effective, the results were confounded by the H1N1 influenza pandemic that resulted in substantially increased hand hygiene behaviors and resources in usual care schools. Therefore, these results should be viewed cautiously. PMID:23069487

    Hand washing with soap is a practice that has long been recognized as a major barrier to the spread of disease in food production, preparation, and service and in health care settings, including hospitals, child care centers, and elder care facilities. Many of these settings present multiple opportunities for spread of pathogens within at-risk populations, and extra vigilance must be applied. Unfortunately, hand hygiene is not always carried out effectively, and both enteric and respiratory diseases are easily spread in these environments. Where water is limited or frequent hand hygiene is required on a daily basis, such as for many patients in hospitals and astronauts in space travel, instant sanitizers or sanitary wipes are thought to be an effective way of preventing contamination and spread of organisms among coworkers and others. Most concerns regarding compliance are associated with the health care field, but the food industry also must be considered. Specific reasons for not washing hands at appropriate times are laziness, time pressure, inadequate facilities and supplies, lack of accountability, and lack of involvement by companies, managers, and workers in supporting proper hand washing. To facilitate improvements in hand hygiene, measurement of compliant and noncompliant actions is necessary before implementing any procedural changes. Training alone is not sufficient for long-lasting improvement. Multiactivity strategies also must include modification of the organization culture to encourage safe hygienic practices, motivation of employees willing to use peer pressure on noncompliant coworkers, a reward and/or penalty system, and an operational design that facilitates regular hand hygiene.

    Objective: The aim of this study was to determine the efficacy of a multimodal hand hygiene intervention program in reducing health care insurance claims for hygiene preventable infections (eg, cold and influenza), absenteeism, and subjective impact on employees. Methods: A 13.5-month prospective, randomized cluster controlled trial was executed with alcohol-based hand sanitizer in strategic workplace locations and personal use (intervention group) and brief hand hygiene education (both groups). Four years of retrospective data were collected for all participants. Results: Hygiene-preventable health care claims were significantly reduced in the intervention group by over 20% (P < 0.05). Absenteeism was positively impacted overall for the intervention group. Employee survey data showed significant improvements in hand hygiene behavior and perception of company concern for employee well-being. Conclusion: Providing a comprehensive, targeted, yet simple to execute hand hygiene program significantly reduced the incidence of health care claims and increased employee workplace satisfaction.

    Millions of people die from diarrheal and respiratory diseases every year due to lack of proper sanitation, hygiene, and access to clean water. The act of handwashing with soap has been found to effectively reduce both diarrheal and respiratory illness, however, handwashing at critical times (i.e. after using the toilet, before preparing food) remains infrequent around the world. This research investigates the potential for alcohol- based hand sanitizer (ABHS) to be an effective and appropriate hand hygiene option in developing countries. A study was conducted to assess the microbiological effectiveness of ABHS, as compared to handwashing with soap and water, in field conditions in Dar es Salaam, Tanzania. A total of 205 participants, including mothers, nurses, students, and teachers, were introduced to ABHS, given a standardized amount (2ml) of product, and instructed on how to use the product correctly. Hand samples were obtained using the hand rinse method before and after the use of ABHS from 152 participants. The other 53 participants were hand sampled before and after handwashing with a non-antimicrobial liquid soap and clean water (prior to using ABHS). Visual inspections of the hands were performed before hand sampling to record the level of dirt on the hands. All hand samples were processed and analyzed by membrane filtration for concentrations of two microbial indicators, enterococci and E. coli. User perceptions of the product and willingness to pay are also documented. The results of this study provide valuable insight on the prospective of promoting ABHS in developing countries and water scarce areas.

Experimental results show that two sanitation agents must be used to satisfy mission requirements: one agent for personal hygiene and one for equipment maintenance. It was also recommended that a water rinse be used with the agents for best results, and that consideration be given to using the agents pressure packed or in aerosol formulations.

    The medical field has long recognized the importance of hand hygiene in preventing health care-associated infections, yet studies indicate that this important task is performed only 40% of the time. Health care workers cite several barriers to optimal performance of hand hygiene, but the time required to perform this task is foremost among them. Introduction of alcohol-based hand rubs, bundled interventions, and incorporation of technologies designed to monitor and promote hand hygiene all represent promising advances in this field.

    This study aimed to assess whether the MDG classifications and JMP sanitation ladder corresponded to hygienic proxies. Latrines were purposefully sampled in urban and rural Tanzania. Three hygienic proxies were measured: E. coli on points of hand contact, helminth at point of foot contact, and number of flies. Additionally, samples were collected from comparable surfaces in the household, and a questionnaire on management and use, combined with a visual inspection of the latrine's design was conducted. In total, 341 latrines were sampled. The MDG classifications "improved" vs "unimproved" did not describe the observed differences in E. coli concentrations. Disaggregating the data into the JMP sanitation ladder, on average "shared" facilities were the least contaminated: 9.2 vs 17.7 ("improved") and 137 E. coli/100 mL ("unimproved") (p = 0.04, p < 0.001). Logistic regression analysis suggests that both the presence of a slab and sharing a facility is protective against faecal-oral exposure (OR 0.18 95% CI 0.10, 0.34 and OR 0.52, 95% CI 0.29, 0.92). The findings do not support the current assumption that shared facilities of an adequate technology should be classified for MDG purposes as "unimproved". PMID:25513885

    Health care-associated infections (HAIs) are a significant issue in the United States and throughout the world, but following proper hand hygiene practices is the most effective and least expensive way to prevent HAIs. Hand hygiene is inexpensive and protects patients and health care personnel alike. The four general types of hand hygiene that should be performed in the perioperative environment are washing hands that are visibly soiled, hand hygiene using alcohol-based products, surgical hand scrubs, and surgical hand scrubs using an alcohol-based surgical hand rub product. Barriers to proper hand hygiene may include not thinking about it, forgetting, skin irritation, a lack of role models, or a lack of a safety culture. One strategy for improving hand hygiene practices is monitoring hand hygiene as part of a quality improvement project, but the most important aspect for perioperative team members is to set an example for other team members by following proper hand hygiene practices and reminding each other to perform hand hygiene.

    The risk of inadequate hand hygiene in food handling settings is exacerbated when water is limited or unavailable, thereby making washing with soap and water difficult. The SaniTwice method involves application of excess alcohol-based hand sanitizer (ABHS), hand "washing" for 15 s, and thorough cleaning with paper towels while hands are still wet, followed by a standard application of ABHS. This study investigated the effectiveness of the SaniTwice methodology as an alternative to hand washing for cleaning and removal of microorganisms. On hands moderately soiled with beef broth containing Escherichia coli (ATCC 11229), washing with a nonantimicrobial hand washing product achieved a 2.86 (±0.64)-log reduction in microbial contamination compared with the baseline, whereas the SaniTwice method with 62 % ethanol (EtOH) gel, 62 % EtOH foam, and 70 % EtOH advanced formula gel achieved reductions of 2.64 ± 0.89, 3.64 ± 0.57, and 4.61 ± 0.33 log units, respectively. When hands were heavily soiled from handling raw hamburger containing E. coli, washing with nonantimicrobial hand washing product and antimicrobial hand washing product achieved reductions of 2.65 ± 0.33 and 2.69 ± 0.32 log units, respectively, whereas SaniTwice with 62 % EtOH foam, 70 % EtOH gel, and 70 % EtOH advanced formula gel achieved reductions of 2.87 ± 0.42, 2.99 ± 0.51, and 3.92 ± 0.65 log units, respectively. These results clearly demonstrate that the in vivo antibacterial efficacy of the SaniTwice regimen with various ABHS is equivalent to or exceeds that of the standard hand washing approach as specified in the U.S. Food and Drug Administration Food Code. Implementation of the SaniTwice regimen in food handling settings with limited water availability should significantly reduce the risk of foodborne infections resulting from inadequate hand hygiene.

    Infectious diseases remain a major cause of death among young people throughout the world. This paper reviews the current knowledge of empirically validated and promising interventions aimed at preventing infectious diseases among children caused by poor hand hygiene in schools. The study used a standard protocol to identify and review the literature and to classify the selected interventions. Approximately ten interventions were found to have a beneficial effect by promoting hand washing and hand hygiene in schools. The study also found that most of the interventions were implemented at elementary school. However, some interventions were also implemented at kindergarten or in child care centers, while others were aimed at university students. Most of the interventions were implemented by teachers, peers and/or external professionals. The study found that hand hygiene is effective regardless of the type of cleaning product used (i.e. antibacterial or plain soap, alcohol-based or alcohol-free hand sanitizer). This study aims to contribute to the understanding of empirically validated and promising interventions and to promote reflection on professional practice in France. PMID:23782636

  20. Surgical hand hygiene: scrub or rub?

    PubMed

    Widmer, A F

    2013-02-01

    Surgical hand hygiene is standard care prior to any surgical procedure. Per-operative glove punctures are observed in almost 30% of all interventions, and a risk factor for postoperative infections. In the past, washing hands with antimicrobial soap and water (surgical scrub) was the norm, mainly with chlorhexidine or iodine. More recently, alcohol-based hand rub has been successfully introduced, showing greater effectiveness, less irritation to the hands, and requiring less time than washing hands. All products should have a remnant effect that delays microbial growth under the gloved hand. Some of the alcohol-based compounds are effective (as determined by the European Norm EN 12791) within 90 s whereas others require 3-5 min, similar to the scrub. The short procedure relies heavily on proper technique and timing, since lowering the exposure time to <90 s leads to significantly lower effectiveness of bacterial killing. Today, surgical hand hygiene should meet EN 12791 in Europe, or other standards, such as the US Food and Drug Administration tentative final monograph norm in the USA. It is best performed by using an alcohol-based hand rub, but a scrub with chlorhexidine-containing soap also meets these standards. PMID:23453175

    2014-12-01

    Alcohol-based surgical scrubs (ABSSs) are used to prevent surgical site infections. Chlorhexidine gluconate (CHG) often is added to enhance persistent germicidal activity. The aim of this study was to determine the influence of ABSS product formulation on efficacy. We evaluated three commercially available ABSS formulations and one control alcohol formulation according to the surgical scrub methodology specified by the US Food and Drug Administration (FDA). Only one ABSS formulation met FDA efficacy requirements when tested at the manufacturer's recommended dosage. In contrast, two ABSS formulations, one of which contained CHG, failed to meet the FDA acceptance criteria for a 3-log10 reduction on day 5, meaning the formulations did not sufficiently reduce bacteria levels on hands on the fifth day of product application. The data suggest that recommendations to include CHG in ABSS formulations should be reconsidered, and product efficacy, skin tolerability, and user acceptability should be evaluated on a case-by-case basis.

    Just over 600 million people used shared sanitation in 2015, but this form of sanitation is not considered 'improved sanitation' or, in the current terminology, 'basic sanitation' by WHO/UNICEF, principally because they are typically unhygienic. Recent research has shown that neighbour-shared toilets perform much better than large communal toilets. The successful development of community-designed, built and managed sanitation-and-water blocks in very poor urban areas in India should be adapted and adopted throughout urban slums in developing countries, with a caretaker employed to keep the facilities clean. Such shared sanitation should be classified as 'basic', sometimes as 'safely-managed', sanitation, so contributing to the achievement of the sanitation target of the Sustainable Development Goals.

    Today about 2.4 billion people in rural and urban areas do not have access to adequate sanitation services. Within 20 years, it is expected that an additional 2 billion will live in towns and cities, mainly in developing countries, demanding sanitation. Still over 90% of sewage in developing countries is discharged untreated, polluting rivers, lakes and coastal areas. Conventional sanitation concepts, based on flush toilets, a water wasting technology, are neither an ecological nor economical solution in both industrialized and developing countries. The water-based sewage systems were designed and built on the premises that human excreta are a waste; suitable only for disposal and that the environment is capable of assimilating this waste. A sanitation system that provides Ecological Sanitation (EcoSan) is a cycle--a sustainable, closed-loop system, which closes the gap between sanitation and agriculture. The EcoSan approach is resource minded and represents a holistic concept towards ecologically and economically sound sanitation. The underlying aim is to close (local) nutrient and water cycles with as less expenditure on material and energy as possible to contribute to a sustainable development. Human excreta are treated as a resource and are usually processed on-site and then treated off-site. The nutrients contained in excreta are then recycled by using them, e.g., in agriculture. EcoSan is a systemic approach and an attitude; single technologies are only means to an end and may range from near-natural wastewater treatment techniques to compost toilets, simple household installations to complex, mainly decentralised systems. These technologies are not ecological per se but only in relation to the observed environment. They are picked from the whole range of available conventional, modern and traditional technical options, combining them to EcoSan systems. The paper presents an introduction to EcoSan principles and concepts including re-use aspects (available

    To prevent diseases associated with inadequate sanitation and poor hygiene, people needing latrines and behavioural interventions must be identified. We compared two indicators that could be used to identify those people. Indicator 1 of household latrine coverage was a simple Yes/No response to the question "Does your household have a latrine?" Indicator 2 was more comprehensive, combining questions about defecation behaviour with observations of latrine conditions. Using a standardized procedure and questionnaire, trained research assistants collected data from 6,599 residents of 16 rural villages in Indonesia. Indicator 1 identified 30.3% as not having a household latrine, while Indicator 2 identified 56.0% as using unimproved sanitation. Indicator 2 thus identified an additional 1,710 people who were missed by Indicator 1. Those 1,710 people were of lower socioeconomic status (p < 0.001), and a smaller percentage practiced appropriate hand-washing (p < 0.02). These results show how a good indicator of need for sanitation and hygiene interventions can combine evidences of both access and use, from self-reports and objective observation. Such an indicator can inform decisions about sanitation-related interventions and about scaling deworming programmes up or down. Further, a comprehensive and locally relevant indicator allows improved targeting to those most in need of a hygiene-behaviour intervention. PMID:27452598

  13. Are constructed treatment wetlands sustainable sanitation solutions?

    PubMed

    Langergraber, Guenter

    2013-01-01

    The main objective of sanitation systems is to protect and promote human health by providing a clean environment and breaking the cycle of disease. In order to be sustainable, a sanitation system has to be not only economically viable, socially acceptable and technically and institutionally appropriate, but it should also protect the environment and the natural resources. 'Resources-oriented sanitation' describes the approach in which human excreta and water from households are recognized as resource made available for reuse. Nowadays, 'resources-oriented sanitation' is understood in the same way as 'ecological sanitation'. For resources-oriented sanitation systems to be truly sustainable they have to comply with the definition of sustainable sanitation as given by the Sustainable Sanitation Alliance (SuSanA, www.susana.org). Constructed treatment wetlands meet the basic criteria of sustainable sanitation systems by preventing diseases, protecting the environment, and being an affordable, acceptable, and simple technology. Additionally, constructed treatment wetlands produce treated wastewater of high quality, which is fostering reuse, which in turn makes them applicable in resources-oriented sanitation systems. The paper discusses the features that make constructed treatment wetlands a suitable solution in sustainable resources-oriented sanitation systems, the importance of system thinking for sustainability, as well as key factors for sustainable implementation of constructed wetland systems.

  15. Household demand for improved sanitation services in Kumasi, Ghana: A contingent valuation study

    NASA Astrophysics Data System (ADS)

    Whittington, Dale; Lauria, Donald T.; Wright, Albert M.; Choe, Kyeongae; Hughes, Jeffrey A.; Swarna, Venkateswarlu

    1993-06-01

    A contingent valuation survey was conducted in Kumasi, Ghana, to estimate households' willingness to pay for two types of improved sanitation services: improved ventilated pit latrines and water closets connected to a sewer system. Over 1200 randomly selected households throughout the city were interviewed. Most households were willing to pay more for improved sanitation service than they were currently paying for their existing sanitation system (mostly public and bucket latrines), but in absolute terms the potential revenues from households are not large, of the order of US$1.40 per household per month (about 1-2% of household income). The results of the study confirm the conventional wisdom that conventional sewerage is not affordable to the vast majority of households without massive government subsidies. On the other hand, it appears that only modest subsidies are required to achieve relatively high levels of coverage with on-site sanitation (improved ventilated pit latrines). This is because improved ventilated pit latrines are much cheaper than conventional sewerage and because most households are willing to pay about as much for a ventilated pit latrine as for a water closet connected to a sewer. Several tests were conducted to check the accuracy of respondents' answers to contingent valuation questions. The findings indicate that contingent valuation surveys can be successfully carried out in cities in developing countries for public services such as sanitation and that reasonably reliable information can be obtained on household demand for different sanitation technologies.

    Hand hygiene is the primary measure to prevent healthcare-associated infections and the spread of antimicrobial resistance. Low staff compliance remains a major problem. Successful promotion requires a multimodal strategy. The World Health Organization (WHO) proposes an approach including at least five components: system change, in particular the recourse to alcohol-based hand rubbing as the new standard of care, staff education using newly developed tools, monitoring and feedback of staff performance, reminders in the workplace, and promotion of an institutional safety climate. Patient participation in hand hygiene promotion is under testing. Early results of the strategy tested in a large number of healthcare settings in both limited- and high-resource countries are extremely encouraging. PMID:19492514

    The American Red Cross and U.S. Centers for Disease Control and Prevention collaborated on a sustainability evaluation of post-hurricane water, sanitation and hygiene (WASH) interventions in Central America. In 2006 and 2009, we revisited six study areas in rural El Salvador, Guatemala, Honduras and Nicaragua to assess sustainability of WASH interventions finalized in 2002, after 1998’s Hurricane Mitch. We used surveys to collect data, calculate indicators and identify factors that influence sustainability. Regional sustainability indicator results showed there was a statistically significant decline in access to water. The presence of sanitation facilities had not changed since the beginning of the project; however, maintenance and use of latrines declined but continued to meet the goal of 75% use after 7 years. The hygiene indicator, hand washing, initially declined and then increased. Declines in water access were due to operational problems related to storm events and population changes. Sanitation facilities were still present and sometimes used even though they reached or surpassed their original design life. Changes in hygiene practices appeared related to ongoing hygiene promotion from outside organizations. These results provide useful input for making WASH programs more sustainable and informing future, more in-depth research into factors influencing sustainability. PMID:26413262

The photosensitizer (PS)-mediated bactericidal effect of light against different types of microorganisms including vegetative bacteria (both in planktonic form and in biofilms), bacterial spores, yeasts, viruses was investigated for both cells in liquid media, and on surface. Bactericidal effect was monitored for different photosensitizer such as TBO and derivatives of rosamine at different concentrations.

Currently, UNICEF and WHO estimate that 1.1 billion people lack access to improved water supplies and 2.6 billion people lack adequate sanitation. Providing safe water and basic sanitation to meet the MDGs will require substantial economic resources, sustainable technological solutions and courageous political will. We review five major challenges to providing safe water and sanitation on a global basis: (1) contamination of water in distribution systems, (2) growing water scarcity and the potential for water reuse and conservation, (3) implementing innovative low-cost sanitation systems, (4) providing sustainable water supplies and sanitation for megacities, and (5) reducing global and regional disparities in access to water and sanitation and developing financially sustainable water and sanitation services.

  20. From conventional to advanced environmental sanitation.

    PubMed

    Schertenleib, R

    2005-01-01

    The basic concept of collecting domestic liquid waste in water-borne sewer systems goes back more than 100 years and became in the last century the conventional approach to sanitation in urban areas. Over the years, these sewage disposal systems had to be successively upgraded by additional sewage treatment plants increasing investment, operating and maintenance costs. Although these conventional sanitation systems could improve significantly the public health situation in those countries who could afford to install and operate them, it is highly questionable, if they are economically and ecologically sustainable. The large number of people in the developing world who still do not have access to adequate sanitation is a clear indication that the conventional approach to sanitation is not adapted to the socio-economic condition prevailing in most countries of Africa, Asia and Latin America. Advanced environmental sanitation is aiming not only to protect public health and the integrity of aquatic ecosystems but also to conserve precious freshwater and non-renewable resources. The Bellagio Principles and the Household Centred Environmental Sanitation Approach (HCES) are suggested as guiding principles and a new approach for planing and designing advanced (sustainable) environmental sanitation systems.

    A large and growing proportion of the global population rely on shared sanitation facilities despite evidence of a potential increased risk of adverse health outcomes compared with individual household latrines (IHLs). We sought to explore differences between households relying on shared sanitation versus IHLs in terms of demographics, sanitation facilities, and fecal exposure. We surveyed 570 households from 30 slums in Orissa, India, to obtain data on demographics, water, sanitation, and hygiene. Latrine spot-checks were conducted to collect data on indicators of use, privacy, and cleanliness. We collected samples of drinking water and hand rinses to assess fecal contamination. Households relying on shared sanitation were poorer and less educated than those accessing IHLs. Individuals in sharing households were more likely to practice open defecation. Shared facilities were less likely to be functional, less clean, and more likely to have feces and flies. No differences in fecal contamination of drinking water or hand-rinse samples were found. Important differences exist among households accessing shared facilities versus IHLs that may partly explain the apparent adverse health outcomes associated with shared sanitation. As these factors may capture differences in risk and promote sanitary improvements, they should be considered in future policy. PMID:26123953

  6. Rural water supply and sanitation (RWSS) coverage in Swaziland: Toward achieving millennium development goals

    NASA Astrophysics Data System (ADS)

    Mwendera, E. J.

    An assessment of rural water supply and sanitation (RWSS) coverage in Swaziland was conducted in 2004/2005 as part of the Rural Water Supply and Sanitation Initiative (RWSSI). The initiative was developed by the African Development Bank with the aim of implementing it in the Regional Member Countries (RMCs), including Swaziland. Information on the RWSS sector programmes, costs, financial requirements and other related activities was obtained from a wide range of national documents, including sector papers and project files and progress reports. Interviews were held with staff from the central offices and field stations of Government of Swaziland (GOS) ministries and departments, non-governmental organizations (NGOs), bilateral and multilateral external support agencies, and private sector individuals and firms with some connection to the sector and/or its programmes. The assessment also involved field visits to various regions in order to obtain first hand information about the various technologies and institutional structures used in the provision of water supplies and sanitation services in the rural areas of the country. The results showed that the RWSS sector has made significant progress towards meeting the national targets of providing water and sanitation to the entire rural population by the year 2022. The assessment indicated that rural water supply coverage was 56% in 2004 while sanitation coverage was 63% in the same year. The results showed that there is some decline in the incidence of water-related diseases, such as diarrhoeal diseases, probably due to improved water supply and sanitation coverage. The study also showed that, with adequate financial resources, Swaziland is likely to achieve 100% coverage of both water supply and sanitation by the year 2022. It was concluded that in achieving its own national goals Swaziland will exceed the Millennium Development Goals (MDGs). However, such achievement is subject to adequate financial resources being

    Context: Footwear should be designed to avoid trauma and injury to the skin of the feet that can favor bacterial and fungal infections. Procedures and substances for sanitizing the interior of shoes are uncommon but are important aspects of primary prevention against foot infections and unpleasant odor. Objective: To evaluate the efficacy of a sanitizing technique for reducing bacterial and fungal contamination of footwear. Design: Crossover study. Setting: Mens Sana basketball team. Patients or Other Participants: Twenty-seven male athletes and 4 coaches (62 shoes). Intervention(s): The experimental protocol required a first sample (swab), 1/shoe, at time 0 from inside the shoes of all athletes before the sanitizing technique began and a second sample at time 1, after about 4 weeks, April 2012 to May 2012, of daily use of the sanitizing technique. Main Outcome Measure(s): The differences before and after use of the sanitizing technique for total bacterial count at 36°C and 22°C for Staphylococcus spp, yeasts, molds, Enterococcus spp, Pseudomonas spp, Escherichia coli, and total coliform bacteria were evaluated. Results: Before use of the sanitizing technique, the total bacterial counts at 36°C and 22°C and for Staphylococcus spp were greater by a factor of 5.8 (95% confidence interval [CI] = 3.42, 9.84), 5.84 (95% CI = 3.45, 9.78), and 4.78 (95% CI = 2.84, 8.03), respectively. All the other comparisons showed a reduction in microbial loads, whereas E coli and coliforms were no longer detected. No statistically significant decrease in yeasts (P = .0841) or molds (P = .6913) was recorded probably because of low contamination. Conclusions: The sanitizing technique significantly reduced the bacterial presence in athletes' shoes. PMID:25415415

    Hand eczema is often a chronic, multifactorial disease. It is usually related to occupational or routine household activities. Exact etiology of the disease is difficult to determine. It may become severe enough and disabling to many of patients in course of time. An estimated 2-10% of population is likely to develop hand eczema at some point of time during life. It appears to be the most common occupational skin disease, comprising 9-35% of all occupational diseases and up to 80% or more of all occupational contact dermatitis. So, it becomes important to find the exact etiology and classification of the disease and to use the appropriate preventive and treatment measures. Despite its importance in the dermatological practice, very few Indian studies have been done till date to investigate the epidemiological trends, etiology, and treatment options for hand eczema. In this review, we tried to find the etiology, epidemiology, and available treatment modalities for chronic hand eczema patients. PMID:24891648

    2014-01-01

    Background Hand hygiene is the cornerstone of infection control and reduces rates of healthcare associated infection. There are limited data evaluating hand hygiene adherence and hand hygiene campaign effect in resource-limited settings, especially in Sub-Saharan Africa. This study assessed the impact of implementing a World Health Organization (WHO)-recommended multimodal hand hygiene campaign at a hospital in Ethiopia. Methods This study included a before-and-after assessment of health care worker (HCW) adherence with WHO hand hygiene guidelines. It was implemented in three phases: 1) baseline evaluation of hand hygiene adherence and hospital infrastructure; 2) intervention (distribution of commercial hand sanitizer and implementation of an abbreviated WHO-recommended multimodal hand hygiene campaign); and 3) post-intervention evaluation of HCW hand hygiene adherence. HCWs’ perceptions of the campaign and hand sanitizer tolerability were assessed through a survey performed in the post-intervention period. Results At baseline, hand washing materials were infrequently available, with only 20% of sinks having hand-washing materials. There was a significant increase in hand hygiene adherence among HCWs following implementation of a WHO multimodal hand hygiene program. Adherence increased from 2.1% at baseline (21 hand hygiene actions/1000 opportunities for hand hygiene) to 12.7% (127 hand hygiene actions /1000 opportunities for hand hygiene) after the implementation of the hand hygiene campaign (OR = 6.8, 95% CI 4.2-10.9). Hand hygiene rates significantly increased among all HCW types except attending physicians. Independent predictors of HCW hand hygiene compliance included performing hand hygiene in the post-intervention period (aOR = 5.7, 95% CI 3.5-9.3), in the emergency department (aOR = 4.9, 95% CI 2.8-8.6), during patient care that did not involve Attending Physician Rounds (aOR = 2.4, 95% CI 1.2-4.5), and after patient contact (aOR = 2

    The right to water and sanitation is an inextricable human right. Water and sanitation are critical determinants for survival in the initial stages of a disaster. An adequate amount of safe water is necessary to prevent death from dehydration, to reduce the risk of water-related disease and to provide for consumption, cooking and personal and domestic hygienic requirements. The main objective of WASH - (Water supply, Sanitation and Hygenie promotion) programmes in disasters is to reduce the transmission of faeco-oral diseases and exposure to disease-bearing vectors through the promotion of: good hygiene practices, the provision of safe drinking water, the reduction of environmental health risks, the conditions that allow people to a healthy life with dignity, comfort and security.

    Objective: Hand hygiene has historically been identified as an important intervention for preventing infection acquired in health care settings. Recently, the advent of waterless, alcohol-based skin degermer and elimination of artificial nails have been recognized as other important interventions for preventing infection. Supplied with this information, the National Infection Control Peer Group convened a KP Hand Hygiene Work Group, which, in August 2001, launched a National Hand Hygiene Program initiative titled “Infection Control: It’s In Our Hands” to increase compliance with hand hygiene throughout the Kaiser Permanente (KP) organization. Design: The infection control initiative was designed to include employee and physician education as well as to implement standard hand hygiene products (eg, alcohol degermers), eliminate use of artificial nails, and monitor outcomes. Results: From 2001 through September 2003, the National KP Hand Hygiene Work Group coordinated implementation of the Hand Hygiene initiative throughout the KP organization. To date, outcome monitoring has shown a 26% increase in compliance with hand hygiene as well as a decrease in the number of bloodstream infections and methycillin-resistant Staphylococcus aureus (MRSA) infections. As of May 2003, use of artificial nails had been reduced by 97% nationwide. Conclusions: Endorsement of this Hand Hygiene Program initiative by KP leadership has led to implementation of the initiative at all medical centers throughout the KP organization. Outcome indicators to date suggest that the initiative has been successful; final outcome monitoring will be completed in December 2003. PMID:26704605

    Bacillus cereus is a spore-forming bacterium. B. cereus occasionally causes nosocomial infections, in which hand contamination with the spores plays an important role. Therefore, hand hygiene is the most important practice for controlling nosocomial B. cereus infections. This study aimed to determine the appropriate hand hygiene procedure for removing B. cereus spores. Thirty volunteers' hands were experimentally contaminated with B. cereus spores, after which they performed 6 different hand hygiene procedures. We compared the efficacy of the procedures in removing the spores from hands. The alcohol-based hand-rubbing procedures scarcely removed them. The soap washing procedures reduced the number of spores by more than 2 log10. Extending the washing time increased the spore-removing efficacy of the washing procedures. There was no significant difference in efficacy between the use of plain soap and antiseptic soap. Handwashing with soap is appropriate for removing B. cereus spores from hands. Alcohol-based hand-rubbing is not effective. PMID:25252644

    The present investigation was carried out to evaluate the sanitary conditions surrounding the food throughout the production stages in some food plants. Observation of the sanitary measures of the studied plants revealed that only 3 out of the 7 plants (42.9%) have acceptable sanitation that complies with the sanitary requirements specified by WHO. Personal hygiene and storage conditions were the most critical problems found in the studied plants. Laboratory examination of nasal and throat swabs and stool samples of workers was carried out to uncover the chronic carriers. Among the food handlers examined 46.3% were positive for intestinal parasites. Bacteriological examination of stool specimens revealed that 4.3% of carriers of Salmonella paratyphi and none were carriers of Vibreo species. Nasal swabs were also positive for Staph. aureus in 29.8% of all the examined swabs. Analysis of the main products of the studied plants revealed generally that the bacterial load of the products of plants having acceptable sanitary conditions was lower than that of the products of the other plants. The frozen vegetable products had a total aerobic mesophilic plate count ranging from 8.1 x 10(4) cfu/g in okra and 3.7 x 10(5) cfu/g in mixed vegetables. The total aerobic plate count of the ice cream (1 x 10(3) cfu/g) complies with specified Egyptian standards. However, the coliform count (9 x 10(1) MPN) was higher than the recommended limit. Lead and cadmium levels were also investigated in all products. The maximum detected level of lead was that of cream wafer (0.94 ppm) followed by banana wafer (0.82 ppm). The two detected levels were higher than Egyptian standards. The lead level in ice cream (0.19 ppm) was also higher than the specified standards. The relatively high levels of lead in cream wafer and ice cream may be attributed to more than one factor; the added color and the old machinery used in some production steps are the most accursed factors. On the other hand, the

    Proper provision of sanitation in emergencies is considered a life-saving intervention. Without access to sanitation, refugees at emergency camps are at a high risk of contracting diseases. Even the most knowledgeable relief agencies have experienced difficulties providing sanitation alternatives in such challenging scenarios. This study developed a computer-based decision support system (DSS) to plan a sanitation response in emergencies. The sanitation alternatives suggested by the DSS are based on a sanitation chain concept that considers different steps in the faecal sludge management, from the toilet or latrine to the safe disposal of faecal matters. The DSS first screens individual sanitation technologies using the user's given input. Remaining sanitation options are then built into a feasible sanitation chain. Subsequently, each technology in the chain is evaluated on a scoring system. Different sanitation chains can later be ranked based on the total evaluation scores. The DSS addresses several deficiencies encountered in the provision of sanitation in emergencies including: the application of standard practices and intuition, the omission of site specific conditions, the limited knowledge exhibited by emergency planners, and the provision of sanitation focused exclusively on the collection step (i.e., just the provision of toilets).

    2015-01-01

    The international response to Haiti’s ongoing cholera outbreak has been multifaceted, including health education efforts by community health workers and the distribution of free water treatment products. Artibonite Department was the first region affected by the outbreak. Numerous organizations have been involved in cholera response efforts in Haiti with many focusing on efforts to improve water, sanitation, and hygiene (WASH). Multiple types of water treatment products have been distributed, creating the potential for confusion over correct dosage and water treatment methods. We utilized qualitative methods in Artibonite to determine the population’s response to WASH messages, use and acceptability of water treatment products, and water treatment and sanitation knowledge, attitudes and practices at the household level. We conducted eighteen focus group discussions (FGDs): 17 FGDs were held with community members (nine among females, eight among males); one FGD was held with community health workers. Health messages related to WASH were well-retained, with reported improvements in hand-washing. Community health workers were identified as valued sources of health information. Most participants noted a paucity of water-treatment products. Sanitation, specifically the construction of latrines, was the most commonly identified need. Lack of funds was the primary reason given for not constructing a latrine. The construction and maintenance of potable water and sanitation services is needed to ensure a sustainable change.

    Lack of adequate sanitation, hygiene and safe portable water are serious global health problems that contribute to deaths of many children under the age of 5 years annually, mainly due to diarrhoeal diseases. This study was set out to determine the extent to which sanitation and hygiene promotion influenced mothers' and children's health in Turkana District; one of the arid Northern frontier Districts of Kenya. A repeat cross-sectional study design with multi-stage sampling method was used. A total of 300 mothers were randomly sampled for interviews in a baseline survey carried out in 2007 and in a post-intervention survey carried out in 2008. Data were collected using questionnaires and analyzed using SPSS for frequencies, cross tabulations and regression amongst other tests. Significant improvements were observed in hand washing practice, presence of hand washing soap at household and refuse pit ownership. In Kakuma Division the proportion of those who washed hands regularly increased from 48.8 to 91.3 % (χ(2) = 7.28, P = 0.122), in Lodwar Central, those who wash hands regularly increased from 85.5 to 89.9 % (χ² = 10.85, P = 0.028) while in Lokichogio, the proportions increased from 77.5 to 93.8 % (χ² = 15.56, P = 0.004). For hand washing soap at household, there was an increase in proportion of those who wash hands with soap from 65 to 78 % (χ² = 3.87, P = 0.049) within the group with no formal education. There was significant reduction of diarrhoea prevalence in children aged less than 5 years. Sanitation and hygiene promotion based on community participatory approaches can lead to significant reduction of diarrhoea in children. PMID:22481274

    1997-01-01

    The Economic and Social Council for Asia and the Pacific (ESCAP) held a regional workshop in Thailand in 1992 to demonstrate how women's involvement at all levels of environmentally sound and sustainable water supply and sanitation programs and projects could be made more effective, easier, and productive. Using the same modules, with the support of other organizations such as the Department of Development Support and Management Services, ESCAP conducted four more workshops in the Philippines, Lao People's Democratic Republic (PDR), Vietnam, and Thailand in 1995. In the Philippines, the National Commission on the Role of Filipino Women expressed its intention to adapt the modules for the country. In the Lao PDR, three project ideas were proposed which would assist the Lao Women Union in gaining knowledge on the planning, implementation, operation, and management of water supply and sanitation projects at the national, regional and project levels. In Vietnam, three main directions for action were identified for the promotion of close and active cooperation between the Rural Water Supply and Environmental Sanitation Centres and the system of the Women Union of Vietnam. In Thailand, the National Committee on Health and Environment of the National Commission on Women's Affairs expressed its willingness to seek budgetary allocation for the promotion of women's role in water supply and sanitation.

    Microbial contamination is a problem in food industry. The effects produced by the metabolic activity of yeasts are diverse. If they are found in high numbers it might affect the organoleptic quality of the product. Zygosaccharomyces is the most frequent contaminant genus in sweetened juices that are not properly processed and stored. The aim of this work was to compare the action of five commercial sanitizers against isolates of Z. rouxii and to determine appropriate concentrations and time of action for the inactivation. Peracetic acid, monochloramine, iodophor and quaternary ammonium compounds were evaluated on different surfaces (stainless steel, plastic and glass) at room temperature for 30 and 60 s. It was possible to achieve a 99.99 of death Efficiency corresponding to 4 log10 of reduction for a contact time of 60 s for 0.5% (v/v) of peracetic acid, monochloramines and 0.5% (w/v) of iodophors, 1% for compound with a base of 8% (v/v) of benzyl chloride and 7.5% (v/v) of glutaraldehyde and 5% for sodium hypochlorite (55 g/L active compound). Stainless steel was successfully sanitized with all the compounds tested, and then it would be the most appropriate for the food industry because this material is also highly resistant to abrasion, to impact and to different chemical treatments. In view of the great variety of sanitizing products, the selection of the best sanitizer will depend on efficiency, safety and cost. PMID:26139934

    2014-09-01

    While the construction of sanitation infrastructure is one of humankind's greatest public health and environmental engineering achievements, its benefits are not yet enjoyed by all. In addition to the billions of people not yet reached by sanitation infrastructure, at least half of systems constructed in developing contexts are abandoned in the years following initial construction. In this research, we target the problem of postconstruction onsite sanitation infrastructure abandonment in rural Guatemala using legitimacy and status theory. Legitimacy and status are established theoretical concepts from organizational theory that reflect cultural alignment and normative support. Crisp set Qualitative Comparative Analysis (csQCA), which uses Boolean algebra to discover combinations of theoretical conditions that produce an outcome of interest, allowed us to describe the various pathways that have caused socially sustainable uptake. We find that three combinations of legitimacy and status theory explain 85% of household cases at a consistency of 0.97. The most practically useful pathway covers 50% of household cases and shows that the combination of consequential legitimacy (a moral understanding of outcomes) and comprehensibility legitimacy (a cognitive model connecting outcomes to processes) is a powerful way to achieve socially sustainable sanitation infrastructure.

    The microbial quality of eggs entering the hatchery represents an important critical control point for biosecurity and pathogen reduction programs in integrated poultry production. The development of safe and effective interventions to reduce microbial contamination on the surface of eggs will be important to improve the overall productivity and microbial food safety of poultry and poultry products. The hydrogen peroxide (H2O2) and ultraviolet (UV) light advanced oxidation process is a potentially important alternative to traditional sanitizers and disinfectants for egg sanitation. The H2O2/UV advanced oxidation process was demonstrated previously to be effective in reducing surface microbial contamination on eggs. In this study, we evaluated treatment conditions affecting the efficacy of H2O2/UV advanced oxidation in order to identify operational parameters for the practical application of this technology in egg sanitation. The effect of the number of application cycles, UV intensity, duration of UV exposure, and egg rotation on the recovery of total aerobic bacteria from the surface of eggs was evaluated. Of the conditions evaluated, we determined that reduction of total aerobic bacteria from naturally contaminated eggs was optimized when eggs were sanitized using 2 repeated application cycles with 5 s exposure to 14 mW cm(-2) UV light, and that rotation of the eggs between application cycles was unnecessary. Additionally, using these optimized conditions, the H2O2/UV process reduced Salmonella by greater than 5 log10 cfu egg(-1) on the surface of experimentally contaminated eggs. This study demonstrates the potential for practical application of the H2O2/UV advanced oxidation process in egg sanitation and its effectiveness in reducing Salmonella on eggshell surfaces.

    : The purpose of this project is to find out which one of the antibacterial hand cleanser (antibacterial bar soap, antibacterial liquid hand soap, and liquid hand sanitizer) is more effective in eliminating microbes. If antibacterial- formula liquid hand soap is used on soiled hands, then it will be more effective in eliminating microbes. Germs are microorganisms that cause disease and can spread from person-to-person. Bacteria are a kind of microbe, an example of which is Transient Flora that is often found on hands. Hand washing prevents germs from spreading to others. During the procedure, swabs were used to take samples before and after the soiled hands had been washed with one of the antibacterial hand cleansers. Nutrient Easygel was poured into petri dishes to harden for 1 day, and then samples were swabbed on the gel. The Petri dishes were placed in an incubator for 24 hours, and then data was recorded accordingly. The antibacterial liquid hand soap was sufficient in eliminating the majority of bacteria. The hands had 65% of the bacteria on them, and after the liquid hand soap was used only 37% of the bacteria remained.

    Water, sanitation, and hygiene (WaSH) in schools contributes to better health and educational outcomes among school-aged children. In 2012, UNICEF Nicaragua and partners conducted a cross-sectional survey of WaSH in 526 schools in 12 low socio-economic status municipalities in Nicaragua. The survey gathered information on: school characteristics; teacher and community participation; water and sanitation infrastructure; and hygiene education and habits. Survey results were analyzed for associations between variables. WaSH coverage was significantly higher in urban than rural areas. Presence of drinking water infrastructure (43%) was lower than sanitation infrastructure (64%). Eighty-one percent of schools had no hand washing stations and 74% of schools lacked soap. Sanitation facilities were not in use at 28% of schools with sanitation infrastructure and 26% of schools with water infrastructure had non-functional systems. Only 8% of schools had budgets to purchase toilet-cleaning supplies and 75% obtained supplies from students’ families. This study generates transferable WaSH sector learnings and new insights from monitoring data. Results can be used by donors, service providers, and policy makers to better target resources in Nicaraguan schools. PMID:26035665

    Introduction Hand hygiene is an important component of infection control efforts. Our primary and secondary goals were to determine the reported rates of hand washing and stethoscope cleaning in emergency medical services (EMS) workers, respectively. Methods We designed a survey about hand hygiene practices. The survey was distributed to various national EMS organizations through e-mail. Descriptive statistics were calculated for survey items (responses on a Likert scale) and subpopulations of survey respondents to identify relationships between variables. We used analysis of variance to test differences in means between the subgroups. Results There were 1,494 responses. Overall, reported hand hygiene practices were poor among pre-hospital providers in all clinical situations. Women reported that they washed their hands more frequently than men overall, although the differences were unlikely to be clinically significant. Hygiene after invasive procedures was reported to be poor. The presence of available hand sanitizer in the ambulance did not improve reported hygiene rates but improved reported rates of cleaning the stethoscope (absolute difference 0.4, p=0.0003). Providers who brought their own sanitizer were more likely to clean their hands. Conclusion Reported hand hygiene is poor amongst pre-hospital providers. There is a need for future intervention to improve reported performance in pre-hospital provider hand washing. PMID:26587098

    Poor sanitation in urban slums results in increased prevalence of diseases and pollution of the environment. Excreta, grey water and solid wastes are the major contributors to the pollution load into the slum environment and pose a risk to public health. The high rates of urbanization and population growth, poor accessibility and lack of legal status in urban slums make it difficult to improve their level of sanitation. New approaches may help to achieve the sanitation target of the Millennium Development Goal (MDG) 7; ensuring environmental sustainability. This paper reviews the characteristics of waste streams and the potential treatment processes and technologies that can be adopted and applied in urban slums in a sustainable way. Resource recovery oriented technologies minimise health risks and negative environmental impacts. In particular, there has been increasing recognition of the potential of anaerobic co-digestion for treatment of excreta and organic solid waste for energy recovery as an alternative to composting. Soil and sand filters have also been found suitable for removal of organic matter, pathogens, nutrients and micro-pollutants from grey water. PMID:22361648

    Aging of the hands results from both natural processes and chronic ultraviolet light exposure. Together, these cause textural and pigmentary changes, excess skin laxity, rhytides, and soft tissue atrophy that presents as prominent bones and tendons with easily visible veins. Many options are available for the reversal of these changes. Photoaging can be improved with chemical peels and light-based treatments (such as Q-switched lasers), resurfacing lasers, intense pulsed light, and photodynamic therapy. Soft tissue atrophy can be corrected with autologous fat, nonanimal stabilized hyaluronic acid, calcium hydroxylapatite, and poly-L lactic acid injections. The literature shows that these treatments have favorable outcomes for most patients; but in order to reduce known complications, it is important to understand the proper use and limitations of each modality.

    1993-10-01

    We studied the antimicrobial efficacy of hand washing with a quick-dry hand washing machine [TE-KIREIKI] employing ultrasonic wave spraying and its incidental alcohol-based product [AROKULIN-E]. The subjects of this study were 10 males who had been instructed not to use any antimicrobial agent for the previous 2 weeks or any hand soap for the previous 5 hours. They pressed their palms on agar before and after washing their hands. After 48-hour incubation at 37 degrees C, the bacterial colonies grown on the agar were counted using the [ASPECT] image processing system. The colony count was expressed as the post-stamp versus pre-stamp percent (%) reduction. Two patterns of hand washing were examined in this study: [A] a 3-second hand wash using an alcohol-based product [AROKULIN-E] and [B] a 30-second hand wash using a nonmedicated detergent soap with running water in addition to hand washing by [A]. The percent (%) reduction after hand washing patterns [A] and [B] were 49.1% and 51.3%. These reduction rates indicated that these patterns did not eradicate bacteria from the hand surface. Therefore, we concluded that this quick-dry hand washing machine employing an ultrasonic wave spraying method combined with an alcohol-based product needs improvement. PMID:8277045

    Veterinary students can be exposed to environmental infectious agents in school that may include zoonotic pathogens. Encouraging effective hand hygiene can minimize the spread of zoonoses and promote public health and the One Health concept among veterinary students. The purpose of this study was to determine if a campaign could improve hand hygiene among veterinary students at extracurricular meetings serving meals. Nine Kansas State University College of Veterinary Medicine (KSU-CVM) extracurricular organizations participated in the study, sanitizer was provided at each meeting, and baseline hand-hygiene data were observed. A hand-hygiene opportunity was defined as any student observed to approach the buffet food line. Sanitizer use (yes/no) and gender (male/female) were recorded. Campaign interventions included a 3.5-minute educational video and a novel motivational poster. The video was presented to all first-year, second-year, and third-year veterinary students. Posters encouraging hand sanitization were displayed on doors and tables alongside sanitizers at each meeting. Observational hand-hygiene data were collected immediately after introduction of interventions and again 3 months later. Environmental sampling for presence of bacteria in and around meeting locations was also performed. Observed hand hygiene was lowest during baseline (11.0% ± 1.7), improved significantly post-intervention (48.8% ± 3.2), and remained improved at 3-month follow-up (33.5% ± 4.0). Females had higher probability of hand sanitizing (35.9% ± 2.2) than males (21.4% ± 2.4) (p<.01). Clostridium perfringens was isolated from 2/42 samples, and Salmonella spp. were isolated from 4/42 samples. A short-term public health campaign targeting veterinary students successfully improved hand hygiene before meals. PMID:24981423

    Inadequate hygiene and sanitation remain leading global contributors to morbidity and mortality in children and adults. One strategy for improving sanitation access is community-led total sanitation (CLTS), in which participants are guided into self-realization of the importance of sanitation through activities called "triggering." This qualitative study explored community members' and stakeholders' sanitation, knowledge, perceptions, and behaviors during early CLTS implementation in Zambia. We conducted 67 in-depth interviews and 24 focus group discussions in six districts in Zambia 12-18 months after CLTS implementation. Triggering activities elicited strong emotions, including shame, disgust, and peer pressure, which persuaded individuals and families to build and use latrines and handwashing stations. New sanitation behaviors were also encouraged by the hierarchical influences of traditional leaders and sanitation action groups and by children's opinions. Poor soil conditions were identified as barriers to latrine construction. Taboos, including prohibition of different generations of family members, in-laws, and opposite genders from using the same toilet, were barriers for using sanitation facilities. CLTS, through community empowerment and ownership, produced powerful responses that encouraged construction and use of latrines and handwashing practices. These qualitative data suggest that CLTS is effective for improving sanitation beliefs and behaviors in Zambia. PMID:26787149

    The porcine gastric mucin binding magnetic bead (PGM-MB) assay was used to evaluate the ability of chlorine, chlorine dioxide, peroxyacetic acid, hydrogen peroxide, and trisodium phosphate to inactivate human norovirus within 10% stool filtrate. One-minute free chlorine treatments at concentrations of 33 and 189 ppm reduced virus binding in the PGM-MB assay by 1.48 and 4.14 log₁₀, respectively, suggesting that chlorine is an efficient sanitizer for inactivation of human norovirus (HuNoV). Five minute treatments with 5% trisodium phosphate (pH~12) reduced HuNoV binding by 1.6 log₁₀, suggesting that TSP, or some other high pH buffer, could be used to treat food and food contact surfaces to reduce HuNoV. One minute treatments with 350 ppm chlorine dioxide dissolved in water did not reduce PGM-MB binding, suggesting that the sanitizer may not be suitable for HuNoV inactivation in liquid form. However a 60-min treatment with 350 ppm chlorine dioxide did reduce human norovirus by 2.8 log₁₀, indicating that chlorine dioxide had some, albeit limited, activity against HuNoV. Results also suggest that peroxyacetic acid has limited effectiveness against human norovirus, since 1-min treatments with up to 195 ppm reduced human norovirus binding by <1 log₁₀. Hydrogen peroxide (4%) treatment of up to 60 min resulted in minimal binding reduction (~0.1 log₁₀) suggesting that H₂O₂ is not a good liquid sanitizer for HuNoV. Overall this study suggests that HuNoV is remarkably resistant to several commonly used disinfectants and advocates for the use of chlorine (sodium hypochlorite) as a HuNoV disinfectant wherever possible.

    By interpreting disasters as opportunities to initiate the fulfilment of development needs, realise the vulnerability of the affected community and environment, and extend the legacy of relief funds and effort, this paper builds upon the concept linking relief, rehabilitation and development (LRRD) in the sanitation sector. It aims to use a composite of case studies to devise a framework for a semi-hypothetical scenario to identify critical components and generic processes for a LRRD action plan. The scenario is based on a latrine wetland sanitation system in a Muslim community. Several sub-frameworks are developed: (i) latrine design; (ii) assessment of human waste treatment; (iii) connective sanitation promotion strategy; and (iv) ecological systems and environmental services for sanitation and development. This scenario illustrates the complex issues involved in LRRD in sanitation work and provides technical notes and references for a legacy plan for disaster relief and development. PMID:25752194

  14. Planning environmental sanitation programmes in emergencies.

    PubMed

    Harvey, Peter A; Reed, Robert A

    2005-06-01

    Environmental sanitation programmes are vital for tackling environmental-related disease and ensuring human dignity in emergency situations. If they are to have maximum impact they must be planned in a rapid but systematic manner. An appropriate planning process comprises five key stages: rapid assessment and priority setting; outline programme design; immediate action; detailed programme design; and implementation. The assessment should be based on carefully selected data, which are analysed via comparison with suitable minimum objectives. How the intervention should be prioritised is determined through objective ranking of different environmental sanitation sector needs. Next, a programme design outline is produced to identify immediate and longer-term intervention activities and to guarantee that apposite resources are made available. Immediate action is taken to meet acute emergency needs while the detailed programme design takes shape. This entails in-depth consultation with the affected community and comprehensive planning of activities and resource requirements. Implementation can then begin, which should involve pertinent management and monitoring strategies. PMID:15910646

    Background: Rural population in developing countries face water, sanitation, and hygiene-related health issues. To objectively highlight these issues, we studied the knowledge, attitude, and practices-related to drinking water and sanitation facilities among the rural population of Chennai, India. Materials and Methods: A cross-sectional study was designed involving individuals over 18 years of age living in Thandalam village, Chennai, India. Basic information about sociodemographic profile and existing drinking water and sanitation related knowledge, attitude, and practices was collected using a modified version of previously validated questionnaire and analyzed. Results: Forty-five percent of the participants were not following any methods of water treatment and among them half of the participants felt that water available to them was clean and did not require any additional treatment. Twenty-five percent of the participants surveyed did not have access to toilets inside their household. Conclusion: There is a need for intervention to educate individuals about drinking water treatment methods, sanitation, and hand washing practices. PMID:26604623

    The purpose of this study was to evaluate the effect of an alcohol-based caries detector (Kurakay) on the surface tension of a conventional sodium hypochlorite (NaOCl) preparation, and a product containing a surface-active agent (Chlor-XTRA). The surface tensions of the following solutions were tested: NaOCl, a mixture of NaOCl and Kurakay 9:1 w/w, Chlor-XTRA, a mixture of Chlor-XTRA and Kurakay 9:1 w/w. Ten measurements per test solution were made at 20°C, using an optical method called the "Pendant drop method", with a commercially available apparatus. The addition of Kurakay reduced the surface tension for NaOCl (p<0.05) whilst no significant difference was detected for Chlor-XTRA (p>0.05). Statistically significant differences between the NaOCl and Chlor-XTRA groups were found (p<0.05). The addition of an alcohol-based caries detector resulted in a reduction of the original surface tension values for NaOCl only. Taking into account the fact that mixtures of NaOCl and Kurakay have been used to assess the penetration of root canal irrigants in vitro, the related changes in surface tension are a possible source of bias.

    Clostridium species and Bacillus spp. are spore-forming bacteria that cause hospital infections. The spores from these bacteria are transmitted from patient to patient via healthcare workers' hands. Although alcohol-based hand rubbing is an important hand hygiene practice, it is ineffective against bacterial spores. Therefore, healthcare workers should wash their hands with soap when they are contaminated with spores. However, the extent of health care worker hand contamination remains unclear. The aim of this study is to determine the level of bacterial spore contamination on healthcare workers' hands. The hands of 71 healthcare workers were evaluated for bacterial spore contamination. Spores attached to subject's hands were quantitatively examined after 9 working hours. The relationship between bacterial spore contamination and hand hygiene behaviors was also analyzed. Bacterial spores were detected on the hands of 54 subjects (76.1%). The mean number of spores detected was 468.3 CFU/hand (maximum: 3300 CFU/hand). Thirty-seven (52.1%) and 36 (50.7%) subjects were contaminated with Bacillus subtilis and Bacillus cereus, respectively. Nineteen subjects (26.8%) were contaminated with both Bacillus species. Clostridium difficile was detected on only one subject's hands. There was a significant negative correlation between the hand contamination level and the frequency of handwashing (r = -0.44, P < 0.01) and a significant positive correlation between the hand contamination level and the elapsed time since last handwashing (r = 0.34, P < 0.01). Healthcare workers' hands may be frequently contaminated with bacterial spores due to insufficient handwashing during daily patient care. PMID:27236515

    Poor sanitation contributes to morbidity and mortality in the developing world, but there is disagreement on what policies can increase sanitation coverage. To measure the effects of alternative policies on investment in hygienic latrines, we assigned 380 communities in rural Bangladesh to different marketing treatments-community motivation and information; subsidies; a supply-side market access intervention; and a control-in a cluster-randomized trial. Community motivation alone did not increase hygienic latrine ownership (+1.6 percentage points, P = 0.43), nor did the supply-side intervention (+0.3 percentage points, P = 0.90). Subsidies to the majority of the landless poor increased ownership among subsidized households (+22.0 percentage points, P < 0.001) and their unsubsidized neighbors (+8.5 percentage points, P = 0.001), which suggests that investment decisions are interlinked across neighbors. Subsidies also reduced open defecation by 14 percentage points (P < 0.001). PMID:25883316

    Handwashing is the most basic method of preventing infection. Hand rubbing with an alcohol-based handrub, is the most efficient and popular method. We found in several case studies that 3 minutes of dry hand rubbing without any disinfectant decreases the number of hand bacteria. In this study of 54 samples taken from 47 test subjects, we tried to determine how effectively this method decreases hand bacterial numbers. Except for 12 samples that were indeterminate, the number of hand bacteria in 36 (85.7%) out of 42 samples decreased. The average rate of decrease was 49.4% and the maximum rate was 98.3%. Although the most effective duration of dry hand rubbing varied among individuals, we estimated that 2 minutes is optimal. As dry hand rubbing without disinfectants decreases hand bacteria, we suggest that it can be an effective alternate method in emergency situations when water, soap or disinfectants are unavailable.

    Objective To estimate the burden of diarrhoeal diseases from exposure to inadequate water, sanitation and hand hygiene in low- and middle-income settings and provide an overview of the impact on other diseases. Methods For estimating the impact of water, sanitation and hygiene on diarrhoea, we selected exposure levels with both sufficient global exposure data and a matching exposure-risk relationship. Global exposure data were estimated for the year 2012, and risk estimates were taken from the most recent systematic analyses. We estimated attributable deaths and disability-adjusted life years (DALYs) by country, age and sex for inadequate water, sanitation and hand hygiene separately, and as a cluster of risk factors. Uncertainty estimates were computed on the basis of uncertainty surrounding exposure estimates and relative risks. Results In 2012, 502 000 diarrhoea deaths were estimated to be caused by inadequate drinking water and 280 000 deaths by inadequate sanitation. The most likely estimate of disease burden from inadequate hand hygiene amounts to 297 000 deaths. In total, 842 000 diarrhoea deaths are estimated to be caused by this cluster of risk factors, which amounts to 1.5% of the total disease burden and 58% of diarrhoeal diseases. In children under 5 years old, 361 000 deaths could be prevented, representing 5.5% of deaths in that age group. Conclusions This estimate confirms the importance of improving water and sanitation in low- and middle-income settings for the prevention of diarrhoeal disease burden. It also underscores the need for better data on exposure and risk reductions that can be achieved with provision of reliable piped water, community sewage with treatment and hand hygiene.

    Algicidal and sanitizing properties of Armazide, a new swimming pool additive, consisting of 12% w/v each of dodecylamine hydrochloride, trimethyl alkyl ammonium chloride, and methyl alkyl dipolyoxypropylene ammonium methyl sulfate in solution, were evaluated by laboratory techniques against algae and sewage. Results indicated it to be highly effective in low concentrations especially in conjunction with low concentrations of chlorine. Swimming pool field tests were found to confirm the laboratory findings. Various treatment levels and methods are described for swimming pools using treatments based upon the actual condition of the pool and water. The use of the product permitted a reduction in chlorine residual in pools resulting in greatly reduced requirements for chlorinating chemicals along with absence of irritation, odor, and other undesirable results usually associated with standard pool chlorination methods.

    2002-03-01

    This study simulated factors that influence the levels of bacteria on foodservice workers' hands. Relevant data were collected from the scientific literature and from laboratory experiments. Literature information collected included: initial bacterial counts on hands and water faucet spigots, bacterial population changes during hand washing as effected by soap type, sanitizing agent, drying method, and the presence of rings. Experimental data were also collected using Enterobacter aerogenes as a surrogate for transient bacteria. Both literature and experimental data were translated into appropriate discrete or probability distribution functions. The appropriate statistical distribution for each phase of the hand washing process was determined. These distributions were: initial count on hands, beta (2.82, 2.32, 7.5); washing reduction using regular soap, beta (3.01, 1.91, -3.00, 0.60); washing reduction using antimicrobial soap, beta (4.19, 2.99, -4.50, 1.50); washing reduction using chlorhexidine gluconate (CHG), triangular (-4.75, -1.00, 0); reductions from hot air drying, beta (3.52, 1.92, -0.20, 1.00); reduction from paper towel drying, triangular (-2.25, -0.75, 0); reduction due to alcohol sanitizer, gamma (-1.23, 4.42) -5.8; reduction due to alcohol-free sanitizer, gamma (2.22, 5.38) -5.00; and the effect of rings, beta (8.55, 23.35, 0.10, 0.45). Experimental data were fit to normal distributions (expressed as log percentage transfer rate): hand-to-spigot transfer, normal (-0.80, 1.09); spigot to hand, normal (0.36, 0.90). Soap with an antimicrobial agent (in particular, CHG) was observed to be more effective than regular soap. Hot air drying had the capacity to increase the amount of bacterial contamination on hands, while paper towel drying caused a slight decrease in contamination. There was little difference in the efficacy of alcohol and alcohol-free sanitizers. Ring wearing caused a slight decrease in the efficacy of hand washing. The experimental data

    The goals of this study were to (1) assess how frequently patients present for evaluation of common hand disorders in relation to hand dominance and (2) evaluate the effect of hand dominance on function in patients with these conditions. The authors hypothesized that (1) the majority of patients who seek evaluation would have a condition that affects the dominant hand, and (2) disability scores would be worse if the dominant hand is involved. They retrospectively reviewed the records of consecutive patients who presented for treatment to their institution with unilateral symptoms of 5 common disorders of the hand: carpal tunnel syndrome (CTS), de Quervain's tenosynovitis (DEQ), lateral epicondylitis (LE), hand osteoarthritis (OA), and trigger finger (TF). The authors assessed the effect of diagnosis and hand dominance on Disabilities of the Arm, Shoulder and Hand (DASH) scores. The study group comprised 1029 patients (379 men and 650 women) with a mean age of 59.5 years. Ninety percent were right-hand dominant. The dominant and nondominant hands were affected with relatively equal frequency for CTS, DEQ, OA, and TF (range, 45%-53%). Patients with LE had a significantly higher incidence of dominant hand involvement. Men had lower DASH scores than women by an average of 7.9 points, and DASH scores were significantly but slightly higher for the overall group (3.2 points) when the dominant side was affected. Men with LE and women with TF and OA had significantly higher DASH scores when their dominant extremity was affected. Common hand disorders such as CTS, DEQ, OA, and TF affect the dominant and nondominant hands in roughly equivalent proportions, whereas LE is more common on the dominant side. Dominant hand involvement results in significantly worse DASH scores, although the magnitude of this is relatively small. Women have significantly higher DASH scores than men for the conditions evaluated. [Orthopedics. 2016; 39(3):e444-e448.]. PMID:27018604

  5. Rural sanitation problems in Uganda--institutional and management aspects.

    2000-01-01

    Rural Uganda faces a lot of problems caused by poor sanitation facilities such as pollution of water sources, a high rate of waterborne diseases, high expenditures on curative health care, and the threat of reduced educational performance of children through illness, early school drop out, especially of girls. Limited budgets and expenditures for the health sector, lack of staff, lack of accountability and transparency are important factors affecting sanitation status on the national level. Other restrictions can be found at the community level, e.g. taboos, cultural and customary beliefs, ignorance, poverty, or in soil conditions. To address the poor level of sanitation, the Government of Uganda has set up both a whole string of laws and guidelines and an institutional and management framework. One main emphasis was placed on the Participatory Hygiene and Sanitation Transformation Programme (PHAST) introduced in 1994 and since then adopted by several non-governmental organisations (NGO's).

    This article demonstrates that the position of dominance enjoyed by state sanitation companies dictates the public policy decision-making process for sanitation in Brazil. These companies' hegemony is explained here through the analysis of a path that generated political and economic incentives that have permitted its consolidation over time. Through the content analysis of the legislation proposed for the sector and the material produced by the stakeholders involved in the approval of new regulations for the sector in 2007, the study identifies the main sources of incentive introduced by the adoption of the National Sanitation Plan, which explain certain structural features of the current sanitation policy and its strong capacity to withstand the innovations proposed under democratic rule.

    Enterobius vermicularis is a helminth that is difficult to control, is found globally, especially in crowded conditions, and can be transmitted from person to person by contaminated hands. A newly developed method for the quantification of helminth eggs on hands was tested among schoolchildren in a rural South African region to look at the role hands play in helminth infection, and to determine the risk factors for hand contamination. The study found 16.6% of participants' hands positive for helminth eggs, with E. vermicularis most commonly identified. Egg concentrations on hands ranged from 0 to 57 eggs/2 hands. Gender, toilet type used at home, and not reporting to wash hands with soap before eating were all associated with the presence of eggs on hands. The study highlights the need to improve sanitation facilities, and promote handwashing with soap in schools to prevent transmission of E. vermicularis. PMID:26169761

    Local governments in both Mexico and the U.S. spend considerable money on public services, which do not always bring the expected results. For instance, a large part of the public budget is destined to solve social and health problems, such as public sanitation. Government has attacked the problem by providing public sanitation infrastructure (such as garbage and recycling receptacles) and by using social ad campaigns. However, these efforts do not always affect the habits of residents and bring the desired changes in city sanitation. This article presents a case study that used a participatory method to address an innovative city sanitation effort: The Clean City Program in Puebla, Mexico. This program adopted social marketing techniques, a discipline born in the 70s when the principles and practices developed to sell products and services started to be applied to sell ideas, attitudes, or behaviors. Social marketing programs have been adopted by governments to change attitudes and behavior in areas such as public services. The article first describes the context and strategies of the program, which included the use of the promotora model to engage community members. The researchers then make use of qualitative data gathered throughout program planning and implementation to evaluate the impact of the social marketing programs and its effectiveness. The article analyzes social, educational, economic, demographic, and cultural factors that influence the effectiveness of sanitation programs and presents recommendations for strategies to engage community members in community sanitation programs.

    Congenital cytomegalovirus (CMV) transmission can occur when women acquire CMV while pregnant. Infection control guidelines may reduce risk for transmission. We studied the duration of CMV survival after application of bacteria to the hands and after transfer from the hands to surfaces and the effectiveness of cleansing with water, regular and antibacterial soaps, sanitizer, and diaper wipes. Experiments used CMV AD169 in saliva at initial titers of 1 × 10(5) infectious particles/ml. Samples from hands or surfaces (points between 0 and 15 min) were placed in culture and observed for at least 2 weeks. Samples were also tested using CMV real-time PCR. After application of bacteria to the hands, viable CMV was recovered from 17/20 swabs at 0 min, 18/20 swabs at 1 min, 5/20 swabs at 5 min, and 4/20 swabs at 15 min. After transfer, duration of survival was at least 15 min on plastic (1/2 swabs), 5 min on crackers and glass (3/4 swabs), and 1 min or less on metal and cloth (3/4 swabs); no viable virus was collected from wood, rubber, or hands. After cleansing, no viable virus was recovered using water (0/22), plain soap (0/20), antibacterial soap (0/20), or sanitizer (0/22). Viable CMV was recovered from 4/20 hands 10 min after diaper wipe cleansing. CMV remains viable on hands for sufficient times to allow transmission. CMV may be transferred to surfaces with reduced viability. Hand-cleansing methods were effective at eliminating viable CMV from hands. PMID:24185855

    Background The Centers for Disease Control and Prevention recommends the use of an alcohol-based handrub for health care worker hand hygiene. The purpose of this study was to examine effects of hand hygiene product and skin condition on the antimicrobial resistance patterns of colonizing hand flora among nurses. Methods Colonizing hand flora of 119 nurses working in 2 neonatal intensive care units was compared during a 22-month crossover study using alcohol handrub or antiseptic soap. Results Altogether, 1442 isolates from 834 hand cultures (mean, 7 cultures/nurse) were obtained. In 3 of 9 regression analyses modeling for resistant staphylococcal flora, the use of antiseptic soap was a significant predictor of resistance, and nurses with damaged skin were 2.79 times more likely to carry Staphylococcus warneri isolates resistant to gentamicin. Conclusion Hand hygiene product and skin condition may influence resistance patterns of hand flora of care providers. PMID:17482994

    The etiology of nosocomial infections, the frequency of contaminated hands with the different nosocomial pathogens, and the role of health care workers' hands during outbreaks suggest that a hand hygiene preparation should at least have activity against bacteria, yeasts, and coated viruses. The importance of efficacy in choosing the right hand hygiene product is reflected in the new Centers for Disease Control and Prevention guideline on hand hygiene (J. M. Boyce and D. Pittet, Morb. Mortal. Wkly. Rep. 51:1-45, 2002). The best antimicrobial efficacy can be achieved with ethanol (60 to 85%), isopropanol (60 to 80%), and n-propanol (60 to 80%). The activity is broad and immediate. Ethanol at high concentrations (e.g., 95%) is the most effective treatment against naked viruses, whereas n-propanol seems to be more effective against the resident bacterial flora. The combination of alcohols may have a synergistic effect. The antimicrobial efficacy of chlorhexidine (2 to 4%) and triclosan (1 to 2%) is both lower and slower. Additionally, both agents have a risk of bacterial resistance, which is higher for chlorhexidine than triclosan. Their activity is often supported by the mechanical removal of pathogens during hand washing. Taking the antimicrobial efficacy and the mechanical removal together, they are still less effective than the alcohols. Plain soap and water has the lowest efficacy of all. In the new Centers for Disease Control and Prevention guideline, promotion of alcohol-based hand rubs containing various emollients instead of irritating soaps and detergents is one strategy to reduce skin damage, dryness, and irritation. Irritant contact dermatitis is highest with preparations containing 4% chlorhexidine gluconate, less frequent with nonantimicrobial soaps and preparations containing lower concentrations of chlorhexidine gluconate, and lowest with well-formulated alcohol-based hand rubs containing emollients and other skin conditioners.

    The Disassembly Sanitization Operation (DSO) process was implemented to support weapon disassembly and disposition by using recycling and waste minimization measures. This process was initiated by treaty agreements and reconfigurations within both the DOD and DOE Complexes. The DOE is faced with disassembling and disposing of a huge inventory of retired weapons, components, training equipment, spare parts, weapon maintenance equipment, and associated material. In addition, regulations have caused a dramatic increase in the need for information required to support the handling and disposition of these parts and materials. In the past, huge inventories of classified weapon components were required to have long-term storage at Sandia and at many other locations throughout the DoE Complex. These materials are placed in onsite storage unit due to classification issues and they may also contain radiological and/or hazardous components. Since no disposal options exist for this material, the only choice was long-term storage. Long-term storage is costly and somewhat problematic, requiring a secured storage area, monitoring, auditing, and presenting the potential for loss or theft of the material. Overall recycling rates for materials sent through the DSO process have enabled 70 to 80% of these components to be recycled. These components are made of high quality materials and once this material has been sanitized, the demand for the component metals for recycling efforts is very high. The DSO process for NGPF, classified components established the credibility of this technique for addressing the long-term storage requirements of the classified weapons component inventory. The success of this application has generated interest from other Sandia organizations and other locations throughout the complex. Other organizations are requesting the help of the DSO team and the DSO is responding to these requests by expanding its scope to include Work-for- Other projects. For example

    In rural Alaskan communities personal health is threatened by energy costs and limited access to clean water, wastewater management, and adequate nutrition. Fuel-­-based energy systems are significant factors in determining local accessibility to clean water, sanitation and food. Increasing fuel costs induce a scarcity of access and impact residents' health. The University of Alaska Fairbanks (UAF) School of Natural Resources and Agricultural Sciences (SNRAS), NASA's Ames Research Center, and USDA Agricultural Research Service (ARS) have joined forces to develop high-efficiency, low­-energy consuming techniques for water treatment and food production in rural circumpolar communities. Methods intended for exploration of space and establishment of settlements on the Moon or Mars will ultimately benefit Earth's communities in the circumpolar north. The initial phase of collaboration is completed. Researchers from NASA Ames Research Center and SNRAS, funded by the USDA­-ARS, tested a simple, reliable, low-energy sewage treatment system to recycle wastewater for use in food production and other reuse options in communities. The system extracted up to 70% of the water from sewage and rejected up to 92% of ions in the sewage with no carryover of toxic effects. Biological testing showed that plant growth using recovered water in the nutrient solution was equivalent to that using high-purity distilled water. With successful demonstration that the low energy consuming wastewater treatment system can provide safe water for communities and food production, the team is ready to move forward to a full-scale production testbed. The SNRAS/NASA team (including Alaska students) will design a prototype to match water processing rates and food production to meet rural community sanitation needs and nutritional preferences. This system would be operated in Fairbanks at the University of Alaska through SNRAS. Long­-term performance will be validated and operational needs of the

    Community-led total sanitation (CLTS) is a participatory approach to addressing open defecation that has demonstrated success in previous studies, yet there is no research on how implementation arrangements and context change effectiveness. We used a quasi-experimental study design to compare two interventions in Ethiopia: conventional CLTS in which health workers and local leaders provided facilitation and an alternative approach in which teachers provided facilitation. In 2012, Plan International Ethiopia trained teachers from 111 villages and health workers and leaders from 54 villages in CLTS facilitation. The trained facilitators then implemented CLTS in their respective villages for a year. Latrine ownership, use, and quality were measured with household surveys. Differences between interventions were explored using surveys and interviews. The decrease in open defecation associated with teacher-facilitated CLTS was 8.2 percentage points smaller than for conventional CLTS (p = 0.048). Teachers had competing responsibilities and initially lacked support from local leaders, which may have lessened their success. Teachers may be more appropriate for a supporting rather than leading role in sanitation promotion because they did demonstrate ability and engagement. Open defecation decreased by 15.3 percentage points overall but did not change where baseline open defecation was below 30%. Ownership of a latrine with stable flooring increased by 8.7 percentage points overall. Improved latrine ownership did not change during the intervention. CLTS is most appropriate where open defecation is high because there were no significant changes in sanitation practices or latrine upgrades where baseline open defecation was low. PMID:27211881

    The Guideline for Hand Hygiene in Health-Care Settings provides health-care workers (HCWs) with a review of data regarding handwashing and hand antisepsis in health-care settings. In addition, it provides specific recommendations to promote improved hand-hygiene practices and reduce transmission of pathogenic microorganisms to patients and personnel in health-care settings. This report reviews studies published since the 1985 CDC guideline (Garner JS, Favero MS. CDC guideline for handwashing and hospital environmental control, 1985. Infect Control 1986;7:231-43) and the 1995 APIC guideline (Larson EL, APIC Guidelines Committee. APIC guideline for handwashing and hand antisepsis in health care settings. Am J Infect Control 1995;23:251-69) were issued and provides an in-depth review of hand-hygiene practices of HCWs, levels of adherence of personnel to recommended handwashing practices, and factors adversely affecting adherence. New studies of the in vivo efficacy of alcohol-based hand rubs and the low incidence of dermatitis associated with their use are reviewed. Recent studies demonstrating the value of multidisciplinary hand-hygiene promotion programs and the potential role of alcohol-based hand rubs in improving hand-hygiene practices are summarized. Recommendations concerning related issues (e.g., the use of surgical hand antiseptics, hand lotions or creams, and wearing of artificial fingernails) are also included. PMID:12461507

    Immediately after the official recognition of Minamata disease (1956.5.l) a study group at Kumamoto University suggested that Minamata disease was caused by food poisoning. The next year, this suggestion was accepted by the Ministry of Health and Welfare (MHW). Prior to the decision to apply the Food Sanitation Act (FSA), the local government asked MHW for the application of FSA. Soon after, the chief of the Public Health Bureau replied to the local government that the application of FSA to the Minamata area was impossible. Epidemiological investigations of residents and polluted areas, therefore, were not carried out. Data essential for the screening for exposed residents were unavailable. The criteria for the screening were presented. The Environmental Agency (EA) presented the criteria in the form of notice in 1971, which were revised in 1977. Notwithstanding the clear difference between the original and revised criteria, EA insisted that these two sets of criteria were quite similar. This insistence by EA and the absence of epidemiological data on residents and polluted area resulted in the present confusion about Minamata disease. The application of FSA was stopped by bureaucrats who had no interest in the environmental problems and by several scientists patronized by stakeholders (Chisso, Japanese Association of Chemical Industries, MHW and EA). Stakeholders suppressed science. PMID:26832624

    This short communication provides insights into water, sanitation and hygiene (WASH) for homeless people through a scoping study conducted in Dhaka, Bangladesh. It investigates homeless access to WASH through the lens of a rights-based approach. It demonstrates that homeless people's denial of their right to WASH reflects their marginal position in society and an unequal distribution of power and opportunities. The study ultimately suggests a rights-based approach to work toward dealing with the root causes of discrimination and marginalisation rather than just the symptoms. For the homeless, who not only lack substantive rights, but also the means through which to claim their rights, an integrated rights-based approach to WASH offers the possibility for social inclusion and significant improvements in their life conditions. Given the unique deprivation of homelessness it is argued that in addressing the lack of access to adequate WASH for homeless people the immediate goal should be the fulfilment and protection of the right to adequate shelter.

    In the 19th century, sanitation solutions were designed and built on the premises that human excreta was a waste suitable only for disposal and that the environment was capable of assimilating the waste. The prevailing view last century was that vapors from smells caused disease, and the best way to deal with excreta was to convey it to rivers and streams where it could be diluted and cleansed. Times have changed, the premises are outdated, and current solutions contribute, either directly or indirectly, to many of the problems faced by society today: water pollution, scarcity of fresh water, food insecurity, destruction and loss of soil fertility, loss of biodiversity, depletion of the ozone layer, and global warming. A common denominator of all these problems is how society deals with its wastes, specifically how it deals with human excrement. We have to rethink past premises, design and build new systems, and contribute to the solving of society's most pressing problems. The panacea of the 19th century is turning out to be the pandora's box of the 21st century. PMID:10842787

    Postoperative infections are uncommon after hand surgery. Infection can delay recovery and contribute to scarring and stiffness. Measures intended to reduce the risk of infection after hand surgery include hand washing, skin preparation, sterile technique, and prophylactic antibiotics. The role of prophylactic antibiotics for small, clean, elective hand surgery procedures lasting less than 2 hours is debated. PMID:25934209

    Nest sanitation is a nearly universal behavior in birds, while egg discrimination is a more specific adaptation that has evolved to counter brood parasitism. These two behaviors are closely related with nest sanitation being the ancestral behavior, and it has been hypothesized to constitute a preadaptation for egg discrimination. However, previous studies found little evidence to support this hypothesis. Here, we conducted an empirical test of the association between nest sanitation and egg discrimination in the barn swallow (Hirundo rustica) by inserting a single non-mimetic model egg or a non-mimetic model egg plus half a peanut shell into host nests. Compared to the rejection rate of single model eggs, barn swallows significantly increased egg rejection frequency if a half peanut shell was simultaneously introduced. Our result for the first time shows the impact of nest sanitation on egg discrimination and demonstrates that nest sanitation can elicit egg discrimination in hosts of brood parasites. This study provided evidence for nest sanitation being a preadaptation to egg discrimination by facilitating egg rejection, thereby significantly advancing our understanding of avian cognition of foreign objects. Furthermore, we suggest that egg discrimination behavior in many accepters and intermediate rejecters may be lost or diluted. Such egg discrimination can be elicited and restored after nest sanitation, implying a sensitive and rapid phenotypic response to increased risk of parasitism. Our study offers a novel perspective for investigating the role of so-called intermediate rejecter individuals or species in the long-term coevolutionary cycle between brood parasites and their hosts.

    In this research, three faecal sludge sanitizing methods-lactic acid fermentation, urea treatment and lime treatment-were studied for application in emergency situations. These methods were investigated by undertaking small scale field trials with pit latrine sludge in Blantyre, Malawi. Hydrated lime was able to reduce the E. coli count in the sludge to below the detectable limit within 1 h applying a pH > 11 (using a dosage from 7% to 17% w/w, depending faecal sludge alkalinity), urea treatment required about 4 days using 2.5% wet weight urea addition, and lactic acid fermentation needed approximately 1 week after being dosed with 10% wet weight molasses (2 g (glucose/fructose)/kg) and 10% wet weight pre-culture (99.8% pasteurised whole milk and 0.02% fermented milk drink containing Lactobacillus casei Shirota). Based on Malawian prices, the cost of sanitizing 1 m³ of faecal sludge was estimated to be €32 for lactic acid fermentation, €20 for urea treatment and €12 for hydrated lime treatment. PMID:26528995

    Pediatric hand injuries are extremely common. Although many hand injuries are adequately managed in the emergency department, some may need evaluation and treatment by a pediatric hand surgeon to ensure a good functional outcome. This article discusses the diagnosis and management of the most common pediatric hand maladies: fingertip injuries/amputation, tendon injuries, and phalangeal and metacarpal fractures. The plastic surgery nurse should be familiar with hand injuries that require intervention to facilitate efficient management and optimal postoperative care. PMID:27606586

    An experimental study was conducted to assess the pathogen removal efficiency of primary treatment of ecological sanitation (eco-san) system. Ash, lime and soil were used as covering and treatment materials of faeces in the system. A significant rise in pH was observed when the faeces were treated with lime and ash, with a pH value of 11.3 and 9, respectively. Lime treatment was effective in complete destruction of faecal coliforms within 24 h while ash treatment took 30 days of storage to give the same result. On the other hand, no immediate destruction of Ascaris ova was observed during primary treatment of eco-san faeces. Dehydration and storage were other parameters which were considered in the experiment. Faecal coliforms tolerated a moisture content of 3% in untreated faeces while a large number of Ascaris lumbricoides eggs were inactivated by the same level of desiccation, even in the absence of alkaline treatment. The study showed a strong direct relationship between moisture content and viability of Ascaris egg (r = 0.806, p = 0.01) and a negative correlation between viability of eggs and storage time (r = -0.895, p = 0.01). Generally, the treatment methods used in this experiment showed a substantial potential of faeces sanitization, with removals ranging from 54 to 100% after a minimum of 40 days storage.

    Abstract Problem Reduction of health-care-associated infections in low- and middle-income countries is hampered by inadequate supplies of soap and water and the lack or high cost of alcohol-based handrubs (ABHs). Approach In 2005, the World Health Organization (WHO) developed and tested two formulations for ABHs that were suitable for production in health-care facilities. In 2011, the feasibility, advantages and costs of the local production of the two formulations – and the barriers to such production – were evaluated in an online survey. Local setting The survey included 34 health-care facilities and 5 private companies in 29 countries. Relevant changes Local production of one of the WHO formulations was feasible in every participating site. Twenty-one (54%) of the sites had replaced a previously used ABH with one of the WHO formulations. In 32 sites, the WHO formulation that had been produced was well tolerated and accepted by health-care workers. The WHO formulations were found to be less expensive than marketed ABHs. Barriers to local production included difficulty in identifying staff with adequate skills, the need for staff training, and constraints in ingredient and dispenser procurement. Lessons learnt The WHO formulations can be easily produced locally at low cost. They are well tolerated and accepted by health-care workers. Potential barriers to their local production – such as their smell and problems in the procurement of ingredients and dispensers and in performing quality control – require further investigation.

    This review article summarizes results on the synthesis of the magnetic materials including modified nickel ferrite (Ni0.9Co0.1Cu0.1Fe1.9O4-δ), yttrium iron garnet (Y3Fe5O12), lanthanum-containing manganites (MxLa1-xMnO3 (M=Pb, Ba or Sr; x=0.3-0.35)), and multiferroics (BiFeO3 and BiFe0.5Mn0.5O3) from polyvinyl alcohol-based gels. It is shown that the ammonium nitrate accelerates destruction of organic components of xerogels and thus Ni0.9Co0.1Cu0.1Fe1.9O4-δ and BiFeO3 can be prepared at record low temperatures (100 and 250 °C, respectively) which are 200-300 °C lower compared to the process where air is used as an oxidizing agent. As for the synthesis of Y3Fe5O12, MxLa1-xMnO3 and BiFe0.5Mn0.5O3, the presence of NH4NO3 favors formation of foreign phases, which ultimately complicate reaction mechanisms and lead to the higher temperature to synthesize target products. Developed methods provide nanoscale magnetic and multiferroic materials with an average particle size of ∼20-50 nm.

    Petting zoos are popular attractions, but can also be associated with zoonotic disease outbreaks. Hand hygiene is critical to reducing disease risks; however, compliance can be poor. Video observation of petting zoo visitors was used to assess animal and environmental contact and hand hygiene compliance. Compliance was also compared over five hand hygiene intervention periods. Descriptive statistics and multivariable logistic regression were used for analysis. Overall hand hygiene compliance was 58% (340/583). Two interventions had a significant positive association with hand hygiene compliance [improved signage with offering hand sanitizer, odds ratio (OR) 3·38, P<0·001; verbal hand hygiene reminders, OR 1·73, P=0·037]. There is clearly a need to improve hand hygiene compliance at this and other animal exhibits. This preliminary study was the first to demonstrate a positive impact of a hand hygiene intervention at a petting zoo. The findings suggest that active, rather than passive, interventions are more effective for increasing compliance. PMID:21371366

    Many commercial sanitizers and disinfectants have been used over the years to control microbial contamination but their efficacy on phages is often unknown. Here, 23 commercial chemical products, including 21 food-grade sanitizers were tested against virulent dairy phages. These food-grade chemicals included oxidizing agents, halogenated agents, alcohols, quaternary ammonium compounds, anionic acids, iodine-based acids, and an amphoteric chemical. Phage P008 was first exposed to each sanitizer for 2 and 15min at room temperature and at two different concentrations, namely the lowest and highest no-rinse sanitizing concentrations. Organic matter (whey or milk) was also added to the testing solutions. At the end of the exposure period, the test solution was neutralized and the number of infectious phages was determined by plaque assays. The five most efficient sanitizers against phage P008 (<4 log of inactivation) were then tested against virulent lactococcal phages P008, CB13, AF6, P1532 of the 936 group, P001 (c2), Q54, and 1358 as well as Lactobacillus plantarum phage B1 and Streptococcus thermophilus phage 2972 using the same protocol. The oxidizing agents and the quaternary ammonium compounds were the most efficient against all phages although phages CB13 and P1532 were less sensitive to these chemicals than the other phages. This study may help in the selection of appropriate chemicals for controlling phage contamination in industrial factories and research laboratories. PMID:24321601

    Background Despite the increasing promotion of alcohol-based hand rubs and the worldwide use of ethanol-based hand rubs in hospitals only few studies have specifically addressed the issue of ethanol absorption when repeatedly applied to human skin. The aim of this study was to assess if ethanol absorption occurs during hygienic and surgical hand disinfection using three different alcohol-based hand-rubs, and to quantify absorption levels in humans. Methods Twelve volunteers applied three hand-rubs containing 95% (hand-rub A), 85% (hand-rub B) and 55% ethanol (hand-rub C; all w/w). For hygienic hand disinfection, 4 mL were applied 20 times for 30 s, with 1 minute break between applications. For surgical hand disinfection, 20 mL of each hand rub was applied to hands and arms up to the level of the elbow 10 times for 3 minutes, with a break of 5 minutes between applications. Blood concentrations of ethanol and acetaldehyde were determined immediately prior and up to 90 minutes after application using head space gas chromatography. Results The median of absorbed ethanol after hygienic hand disinfection was 1365 mg (A), 630 mg (B), and 358 mg (C). The proportion of absorbed ethanol was 2.3% (A), 1.1% (B), and 0.9% (C). After surgical hand disinfection, the median of absorbed ethanol was 1067 mg (A), 1542 mg (B), and 477 mg (C). The proportion of absorbed ethanol was 0.7% (A), 1.1% (B), and 0.5% (C). The highest median acetaldehyde concentration after 20 hygienic hand disinfections was 0.57 mg/L (hand-rub C, after 30 min), after 10 surgical hand disinfections 3.99 mg/L (hand-rub A, after 20 minutes). Conclusion The overall dermal and pulmonary absorption of ethanol was below toxic levels in humans and allows the conclusion that the use of the evaluated ethanol-based hand-rubs is safe.

    In the course of a successful collaboration between the Centers for Disease Control and Prevention (CDC) and the cruise ship industry on reducing common-source outbreaks, CDC's Vessel Sanitation Program (VSP) has expanded its training, education, and cruise ship inspection programs. The study reported here evaluated 15 years of ship sanitation inspection data from the National Center for Environmental Health and assessed performance in specific sanitation categories from 1996 to 2005. During the period 1990-2005, scores from cruise ship environmental sanitation inspections steadily improved. The percentage of inspections with violations decreased among five of nine categories. Those five categories were Washing Facilities, Contact Surfaces, Facility Maintenance, Food Handling, and Communicable Disease Practices. Inspection violations increased proportionally in the categories of Swimming Pools and Water System Protection/Chart Recording. Overall continued good performance in most sanitation categories is likely attributable to on-site training during inspections, improvements in ship construction, and a switch from hot-holding temperatures to time limits as a public health control for foods on display.

    2015-06-01

    Non-networked sanitation technologies use no sewer, water or electricity lines. Based on a review of 45 commercially distributed technologies, 12 (representing three concepts) were selected for a detailed audit. They were located in six countries of Africa and Asia. The safety of users was generally assured and the costs per use were not excessive, whereas costs were fully transparent for only one technology surveyed. A main drawback was insufficient quality of the byproducts from on-site treatment, making recycling in agriculture a hygienic and environmental risk. Further, no technology was sufficiently mature (requiring e.g. to shift wastes by hand). In order to promote further development and give producers of mature products a competitive advantage, the paper proposes a certification of technologies to confirm the fulfillment of basic requirements to make them attractive for future users.

    In Japan, sanitation coverage is exceeded 70% and sanitary conditions have improved. However in the future, these facilities need to be rebuilt. For that, much money will be needed. On the other hand, prolonged population decrease is predicted in Japan, so it is feared that unsound management caused by the declining of sewerage charge. In this study, costs required for the future were calculated by targeting Asahikawa, Hokkaido Prefecture which is already served by sewerage treatment system. As a result, it was found that maintaining of current sewage treatment system would be cheaper than introduction of novel individual treatment system in Asahikawa. In addition, it was turned out that cost reduction is possible in the case of rebuilding sewage pipe efficiently than maintaining the status quo.

  1. Exploring the determinants of sanitation success in Sub-Saharan Africa.

    Sub-Saharan Africa (SSA) missed the Millennium Development Goal (MDG) sanitation target by a wide margin. However, there are a few African countries which made remarkable progress towards achieving the sanitation target. While the general factors that influence sanitation success are widely known, some of the few studies that have investigated the SSA sanitation situation have arrived at different conclusions regarding the determinants of sanitation success. The objectives of this paper were to establish the key determinants of sanitation success in SSA countries and to classify the SSA countries based on factors associated with sanitation success. This was achieved by analysing data drawn from 46 SSA countries. An objective methodological approach, using regression and cluster analyses to reveal the underlying sanitation success factors, has been adopted. A total of 11 economic and socio-political independent variables were tested against the dependent variable; proportion of the 2015 population that has gained access to sanitation since 2000. Regression results showed consistent and robust association between sanitation success and education for the national, rural and socio-political samples (p values 0.018-0.038). These results suggest that the level of education contributed to sanitation success in SSA during the MDG period. For the urban sample, a negative association was demonstrated between sanitation success and access to improved water sources (p = 0.034). This implies that countries which made huge sanitation gains had low coverage of improved water sources. The results from cluster analysis showed that countries which achieved great sanitation success were characterized by the highest education levels, incomes, population densities, political stability and high proportions of urban population. The knowledge of the key determinants of sanitation success could help in the formulation and design of appropriate policies and interventions to improve

    Deep eutectic solvents (DESs) are basically molten salts that interact by forming hydrogen bonds between two added components at a ratio where eutectic point reaches a melting point lower than that of each individual component. Their remarkable physicochemical properties (similar to ionic liquids) with remarkable green properties, low cost and easy handling make them a growing interest in many fields of research. Therefore, the objective of pursuing this study is to analyze the potential of alcohol-based DES as an extraction medium for rotenone extraction from Derris elliptica roots. DES was prepared by a combination of choline chloride, ChCl and 1, 4-butanediol at a ratio of 1/5. The structure of elucidation of DES was analyzed using FTIR, {sup 1}H-NMR and {sup 13}C-NMR. Normal soaking extraction (NSE) method was carried out for 14 hours using seven different types of solvent systems of (1) acetone; (2) methanol; (3) acetonitrile; (4) DES; (5) DES + methanol; (6) DES + acetonitrile; and (7) [BMIM] OTf + acetone. Next, the yield of rotenone, % (w/w), and its concentration (mg/ml) in dried roots were quantitatively determined by means of RP-HPLC. The results showed that a binary solvent system of [BMIM] OTf + acetone and DES + acetonitrile was the best solvent system combination as compared to other solvent systems. It contributed to the highest rotenone content of 0.84 ± 0.05% (w/w) (1.09 ± 0.06 mg/ml) and 0.84 ± 0.02% (w/w) (1.03 ± 0.01 mg/ml) after 14 hours of exhaustive extraction time. In conclusion, a combination of the DES with a selective organic solvent has been proven to have a similar potential and efficiency as of ILs in extracting bioactive constituents in the phytochemical extraction process.

  9. Does global progress on sanitation really lag behind water? An analysis of global progress on community- and household-level access to safe water and sanitation.

    Safe drinking water and sanitation are important determinants of human health and wellbeing and have recently been declared human rights by the international community. Increased access to both were included in the Millennium Development Goals under a single dedicated target for 2015. This target was reached in 2010 for water but sanitation will fall short; however, there is an important difference in the benchmarks used for assessing global access. For drinking water the benchmark is community-level access whilst for sanitation it is household-level access, so a pit latrine shared between households does not count toward the Millennium Development Goal (MDG) target. We estimated global progress for water and sanitation under two scenarios: with equivalent household- and community-level benchmarks. Our results demonstrate that the "sanitation deficit" is apparent only when household-level sanitation access is contrasted with community-level water access. When equivalent benchmarks are used for water and sanitation, the global deficit is as great for water as it is for sanitation, and sanitation progress in the MDG-period (1990-2015) outstrips that in water. As both drinking water and sanitation access yield greater benefits at the household-level than at the community-level, we conclude that any post-2015 goals should consider a household-level benchmark for both.

    Background: Chlorhexidine is well known for its antiplaque effect. However, the mouthrinse based chlorhexidine antiplaque efficiency may vary according to the formulation of the final product. The aim of the present study was to compare anti-plaque effectiveness of two commercial mouthrinses: 0.12 % Chlorhexidine alcohol base (CLX-A) versus a diluted 0.1% Chlorhexidine non-alcohol base with 0.1% of Formaldehyde (CLX-F). Material and Methods: the study was a seven day randomized, double-blind, placebo-controlled trial including 30 volunteers. At the start, all participants received a dental prophylaxis. Over 7 days experimental non-brushing period, during which subjects abstained from all forms of mechanical oral hygiene, one group test rinsed twice daily with 15ml of an alcohol base 0.12% Chlorhexidine mouthrinse. The second group test used 15ml of alcohol free 0.1% Chlorhexidine mouthrinse base 0.1% formaldehyde twice daily. The negative control group used a placebo. Plaque indexes were recorded in all volunteers prior to treatment at Day 0, 1 and 7. Results: After 7 days, the mean plaque index for the first group was 0.76±0.38 compared with a mean plaque index of 1.43±0.56 for the second group. The difference in plaque scores between the groups was statistically significant. Conclusion: the results of this study showed that rinsing with an alcohol base 0.12% Chlorhexidine mouthrinse is significantly different from rinsing with an alcohol free 0.1% Chlorhexidine mouthrinse on plaque inhibition. Key words:Chlorhexidine, dental plaque, mouthrinse, alcohol, formaldehyde. PMID:23229237

    An estimated 800,000 people do not have access to improved water sources, and 2.5 billion are without access to improved sanitation. As a result, an estimated 1800 children under 5 years of age die every day from preventable diseases related to water, sanitation & hygiene; more are ill or stunted. To sustainably improve people's health, actors in the water sector at all levels should use flexible, integrated approaches focused on behavior change and service delivery. Approaches and technologies should be as simple as possible while still protecting human health and the environment. Remember, it's not just about the toilet. PMID:24566351

    Sanitation services play a critical role in controlling transmission of numerous waterborne pathogens, especially viruses that cause acute gastroenteritis and hepatitis. The viral agents with the greatest public health impact are hepatitis A virus, rotaviruses and noroviruses, adenoviruses, and enteroviruses, contaminating many Brazilian aquatic ecosystems. Heavy circulation of viruses in the environment has been related to inadequate local sanitary conditions, including incomplete coverage of services or inefficacy of conventional technologies in eliminating or reducing the viral load in water or sewage. This study reviews the relations between virology, health, and sanitation, emphasizing the epidemiology of waterborne viral infections and their public health impact. PMID:25166934

  14. Skin care: an essential component of hand hygiene and infection control.

    PubMed

    Bissett, Linda

    Skin care is an important component of hand hygiene and also infection prevention education programmes relating to hand hygiene (Bissett, 2007a,b). Hand hygiene is the term commonly used to describe hand washing using plain soap or antiseptic soaps and hand rubbing using waterless antiseptic products or alcohol-based products. The importance of effective hand hygiene is well documented (Larson, 1997; Boyce et al, 2002; Horton and Parker, 2002) and can be achieved by following the six-step technique used for hand washing as illustrated by the Royal College of Nursing (2000). During hand washing, hand soaps not only remove soils, but also the natural oils that protect the skin. This can vary depending on the frequency of hand washing, the temperature of the water and the ability of the soap to be rinsed from the surface of the hands (Starobin, 2007). This article aims to examine the evidence available to enable healthcare staff to make an informed decision on the importance of following a skin care regime to reduce the risk of bacterial loading on the hands caused by damaged skin. This would consequently lead to an improvement in hand hygiene efficacy. PMID:18026035

    2011-01-01

    Background On 1st March 2010, a major landslide occurred on Mt. Elgon in Eastern Uganda. This was triggered by heavy rains that lasted over three months. The landslide buried three villages in Bududa district, killing over 400 and displacing an estimate of 5,000 people. A comprehensive assessment of water, sanitation and hygiene was urgently needed to inform interventions by the Ministries of Health, and Relief, Disaster Preparedness and Refugees, Uganda. Methods This was a cross-sectional study where both qualitative and quantitative data were collected two weeks after the disaster. Quantitative interviews involved 397 heads of households and qualitative methods comprised of 27 Key Informant interviews, four focus group discussions and observations. The survey quantified water safety (collection, treatment, storage) and hygiene practices. This was supplemented and triangulated with qualitative data that focused on community perceptions and beliefs regarding water and sanitation needs and practices. Quantitative data was entered in Epi-Info Version 3.2.2 software and then exported to SPSS Version 12 for analysis. Summary statistics and proportions were generated and bi-variable analysis performed for selected variables. Associations were assessed using odds ratios at 95% confidence intervals. Qualitative data was analyzed using content analysis. Results Qualitative results showed that there were strong traditional beliefs governing water use and human excreta disposal. The use of river Manafwa water for household consumption was observed to potentially lead to disease outbreaks. Water from this river was reported tastier and the community culturally saw no need to boil drinking water. Latrines were few (23 for 5000 people), shallow, dirty (70% reported flies, 60% fecal littering), not separated by sex and had limited privacy and no light at night. This affected their use. Males were 3 times more likely to wash hands with soap after latrine use than females (OR = 3

    A natural exposure field trial a with positive control was conducted to evaluate bacteriological efficacy and teat conditioning qualities of an experimental postmilking teat dip. An experimental 1% iodine postmilking teat sanitizer with a 10% emollient system was compared with a 1% iodine plus 10% glycerin teat sanitizer. Efficacy of the two sanitizers was equivalent for all new IMI, major pathogens, and environmental pathogens. The products were not equivalent for efficacy against coliforms and coagulase-negative staphylococci. Fewer coliform IMI were diagnosed in the control group than in the treatment group. Differences were determined for efficacy against coagulase-negative staphylococci in favor of the treatment product. The products were equivalent for all clinical mastitis, including previously existing IMI that became clinical. The products were not equivalent for all or new clinical IMI with major pathogens, all environmental pathogens, or coliforms. Fewer infections were diagnosed in the control group than in the treatment group. Teat end and teat skin conditions improved with the use of the triple emollient, postmilking teat sanitizer under the winter conditions experienced during this field trial. PMID:8169282

    2011-01-01

    Analysis of relationships among national wealth, access to improved water supply and sanitation facilities, and population health indices suggests that the adequacy of water resources at the national level is a poor predictor of economic development--namely, that low water stress is neither necessary nor sufficient for economic development at the present state of water stress among Pacific Rim nations. Although nations differ dramatically in terms of priority provided to improved water and sanitation, there is some level of wealth (per capita GNP) at which all nations promote the development of essential environmental services. Among the Pacific Rim countries for which there are data, no nation with a per capita GNP > US$18,000 per year has failed to provide near universal access to improved water supply and sanitation. Below US$18,000/person-year, however, there are decided differences in the provision of sanitary services (improved water supply and sanitation) among nations with similar economic success. There is a fairly strong relationship between child mortality/life expectancy and access to improved sanitation, as expected from the experiences of developed nations. Here no attempt is made to produce causal relationships among these data. Failure to meet Millennium Development Goals for the extension of improved sanitation is frequently evident in nations with large rural populations. Under those circumstances, capital intensive water and sanitation facilities are infeasible, and process selection for water/wastewater treatment requires an adaptation to local conditions, the use of appropriate materials, etc., constraints that are mostly absent in the developed world. Exceptions to these general ideas exist in water-stressed parts of developed countries, where water supplies are frequently augmented by water harvesting, water reclamation/reuse, and the desalination of brackish water resources. Each of these processes involves public acceptance of water

  5. A physiological perspective for utility or futility of alcohol-based hand rub gel against nausea-vomiting: is it P-6 acupoint or transnasal aroma?

    PubMed

    Gupta, Deepak; Mazumdar, Ashish; Stellini, Michael

    2014-09-01

    Nausea-vomiting is a common and unpleasant phenomenon with numerous underlying mechanisms and pathways that are not always well elucidated. In clinical practice, refractory nausea-vomiting is encountered in several settings. Antiemetic medications may reduce these symptoms but are not always effective in all patients. In the absence of a well-defined optimal strategy for management of nausea-vomiting, the search for better approaches to treat this distressing symptom continues. One of the alternative treatment approaches is a compounded formulation called ABHR gel that is comprised of multiple antiemetic medications and has been shown to be useful for symptomatic relief in some patients with refractory nausea-vomiting. It has been suggested that alternative mechanisms should be explored to explain the perceived efficacy of ABHR gel, because transdermal absorption leading to nil-to-minimal or subtherapeutic blood concentrations of active ingredients does not explain the role of ABHR gel in the treatment of nausea-vomiting. In the current paper, we discuss possible mechanisms that may explain ABHR transdermal gel's efficacy. Compounded ABHR transdermal gel formulation's efficacy in antagonizing nausea-vomiting that has been recently questioned may be explained by alternative mechanisms mediated through the P-6 acupoint stimulation and facial-nasal, cooling-related counterstimulation.

  6. Adopt or Adapt: Sanitation Technology Choices in Urbanizing Malawi.

    PubMed

    Chunga, Richard M; Ensink, Jeroen H J; Jenkins, Marion W; Brown, Joe

    2016-01-01

    This paper presents the results of a mixed-methods study examining adaptation strategies that property owners in low-income, rapidly urbanizing areas in Malawi adopt to address the limitations of pit latrines, the most common method of disposing human excreta. A particular challenge is lack of space for constructing new latrines as population density increases: traditional practice has been to cap full pits and simply move to a new site, but increasing demands on space require new approaches to extend the service life of latrines. In this context, we collected data on sanitation technology choices from January to September 2013 through 48 in-depth interviews and a stated preference survey targeting 1,300 property owners from 27 low-income urban areas. Results showed that property owners with concern about space for replacing pit latrines were 1.8 times more likely to select pit emptying service over the construction of new pit latrines with a slab floor (p = 0.02) but there was no significant association between concern about space for replacing pit latrines and intention to adopt locally promoted, novel sanitation technology known as ecological sanitation (ecosan). Property owners preferred to adapt existing, known technology by constructing replacement pit latrines on old pit latrine locations, reducing the frequency of replacing pit latrines, or via emptying pit latrines when full. This study highlights potential challenges to adoption of wholly new sanitation technologies, even when they present clear advantages to end users. To scale, alternative sanitation technologies for rapidly urbanising cities should offer clear advantages, be affordable, be easy to use when shared among multiple households, and their design should be informed by existing adaptation strategies and local knowledge.

Results showed that property owners with concern about space for replacing pit latrines were 1.8 times more likely to select pit emptying service over the construction of new pit latrines with a slab floor (p = 0.02) but there was no significant association between concern about space for replacing pit latrines and intention to adopt locally promoted, novel sanitation technology known as ecological sanitation (ecosan). Property owners preferred to adapt existing, known technology by constructing replacement pit latrines on old pit latrine locations, reducing the frequency of replacing pit latrines, or via emptying pit latrines when full. This study highlights potential challenges to adoption of wholly new sanitation technologies, even when they present clear advantages to end users. To scale, alternative sanitation technologies for rapidly urbanising cities should offer clear advantages, be affordable, be easy to use when shared among multiple households, and their design should be informed by existing adaptation strategies and local knowledge.

    Tropical diabetic hand syndrome (TDHS) is a terminology used to describe a specific complication affecting patients with diabetes mellitus in the tropics. The syndrome encompasses a localized cellulitis with variable swelling and ulceration of the hands to progressive, fulminant hand sepsis, potentially fatal. Since this syndrome is less recognized it is often under-reported. Authors present two cases of TDHS and emphasize on aggressive glycemic control and surgical therapy to prevent potential crippling or fatal complications. PMID:20165601

    The neural control of hand movement involves coordination of the sensory, motor, and memory systems. Recent studies have documented the motor coordinates for hand shape, but less is known about the corresponding patterns of somatosensory activity. To initiate this line of investigation, the present study characterized the sense of hand shape by evaluating the influence of differences in the amount of grasping or twisting force, and differences in forearm orientation. Human subjects were asked to use the left hand to report the perceived shape of the right hand. In the first experiment, six commonly grasped items were arranged on the table in front of the subject: bottle, doorknob, egg, notebook, carton, and pan. With eyes closed, subjects used the right hand to lightly touch, forcefully support, or imagine holding each object, while 15 joint angles were measured in each hand with a pair of wired gloves. The forces introduced by supporting or twisting did not influence the perceptual report of hand shape, but for most objects, the report was distorted in a consistent manner by differences in forearm orientation. Subjects appeared to adjust the intrinsic joint angles of the left hand, as well as the left wrist posture, so as to maintain the imagined object in its proper spatial orientation. In a second experiment, this result was largely replicated with unfamiliar objects. Thus, somatosensory and motor information appear to be coordinated in an object-based, spatial-coordinate system, sensitive to orientation relative to gravitational forces, but invariant to grasp forcefulness.

    Background and Methods Cholera remains a significant threat to global public health with an estimated 100,000 deaths per year. Water, sanitation and hygiene (WASH) interventions are frequently employed to control outbreaks though evidence regarding their effectiveness is often missing. This paper presents a systematic literature review investigating the function, use and impact of WASH interventions implemented to control cholera. Results The review yielded eighteen studies and of the five studies reporting on health impact, four reported outcomes associated with water treatment at the point of use, and one with the provision of improved water and sanitation infrastructure. Furthermore, whilst the reporting of function and use of interventions has become more common in recent publications, the quality of studies remains low. The majority of papers (>60%) described water quality interventions, with those at the water source focussing on ineffective chlorination of wells, and the remaining being applied at the point of use. Interventions such as filtration, solar disinfection and distribution of chlorine products were implemented but their limitations regarding the need for adherence and correct use were not fully considered. Hand washing and hygiene interventions address several transmission routes but only 22% of the studies attempted to evaluate them and mainly focussed on improving knowledge and uptake of messages but not necessarily translating this into safer practices. The use and maintenance of safe water storage containers was only evaluated once, under-estimating the considerable potential for contamination between collection and use. This problem was confirmed in another study evaluating methods of container disinfection. One study investigated uptake of household disinfection kits which were accepted by the target population. A single study in an endemic setting compared a combination of interventions to improve water and sanitation infrastructure, and

    Globally, millions of people lack access to improved water, sanitation and hygiene (WASH). Disabled people, disadvantaged both physically and socially, are likely to be among those facing the greatest inequities in WASH access. This study explores the WASH priorities of disabled people and uses the social model of disability and the World Health Organization's International Classification of Functioning, Disability and Health (ICF) framework to look at the relationships between impairments, contextual factors and barriers to WASH access. 36 disabled people and 15 carers from urban and rural Malawi were purposively selected through key informants. The study employed a range of qualitative methods including interviews, emotion mapping, free-listing of priorities, ranking, photo voice, observation and WASH demonstrations. A thematic analysis was conducted using nVivo 10. WASH access affected all participants and comprised almost a third of the challenges of daily living identified by disabled people. Participants reported 50 barriers which related to water and sanitation access, personal and hand hygiene, social attitudes and participation in WASH programs. No two individuals reported facing the same set of barriers. This study found that being female, being from an urban area and having limited wealth and education were likely to increase the number and intensity of the barriers faced by an individual. The social model proved useful for classifying the majority of barriers. However, this model was weaker when applied to individuals who were more seriously disabled by their body function. This study found that body function limitations such as incontinence, pain and an inability to communicate WASH needs are in and of themselves significant barriers to adequate WASH access. Understanding these access barriers is important for the WASH sector at a time when there is a global push for equitable access. PMID:27171520

  15. Why do households invest in sanitation in rural Benin: Health, wealth, or prestige?

    Seventy percent of the rural population in sub-Saharan Africa does not use adequate sanitation facilities. In rural Benin, as much as 95% of the population does not use improved sanitation. By analyzing a representative sample of 2000 rural households, this paper explores why households remain without latrines. Our results show that wealth and latrine prices play the most decisive role for sanitation demand and ownership. At current income levels, sanitation coverage will only increase to 50% if costs for construction are reduced from currently 190 USD to 50 USD per latrine. Our analysis also suggests that previous sanitation campaigns, which were based on prestige and the allure of a modern lifestyle as motives for latrine construction, have had no success in increasing sanitation coverage. Moreover, improved public health, which is the objective of public policies promoting sanitation, will not be effective at low sanitation coverage rates. Fear at night, especially of animals, and personal harassment, are stated as the most important motivational factors for latrine ownership and the intention to build one. We therefore suggest changing the message of sanitation projects and introduce new low-cost technologies into rural markets; otherwise, marketing strategies will continue to fail in increasing sanitation demand.

    The 2013 Kumbh Mela, a Hindu religious festival and the largest human gathering on earth, drew an estimated 120 million pilgrims to bathe at the holy confluence of the Ganga (Ganges) and Yamuna rivers. To accommodate the massive numbers, the Indian government constructed a temporary city on the flood plains of the two rivers and provided it with roads, electricity, water and sanitation facilities, police stations, and a tiered healthcare system. This phenomenal operation and its impacts have gone largely undocumented. To address this gap, the authors undertook an evaluation and systematic monitoring initiative to study preparedness and response to public health emergencies at the event. This paper describes the water, sanitation, and hygiene components, with particular emphasis on preventive and mitigation strategies; the capacity for surveillance and response to diarrheal disease outbreaks; and the implications of lessons learned for other mass gatherings.

    Haiti has the lowest rates of access to improved water and sanitation infrastructure in the western hemisphere. This situation was likely exacerbated by the earthquake in 2010 and also contributed to the rapid spread of the cholera epidemic that started later that same year. This report examines the history of the water, sanitation, and hygiene (WASH) sector in Haiti, considering some factors that have influenced WASH conditions in the country. We then discuss the situation sine the earthquake and subsequent cholera epidemic, and the responses to those events. Finally, drawing on Haiti's National Plan of Action for the Elimination of Cholera in Haiti 2013-2022, we suggest some actions that could help bring about long-term WASH improvements for the future. Because the current WASH situation has evolved over decades of limited attention and resources, it will take a long-term, sustained effort to improve the situation. PMID:24106193

    The article explores the intersection between child rights, water scarcity, sanitation, and the human security paradigm. The recognition of child rights has been advanced through the 1989 Convention on the Rights of the Child and other international legal instruments, while water rights are increasingly affirmed in international law and through the historic July 2010 United Nations General Assembly resolution that strengthened the legal foundation for water security and human rights. Yet there remains a development gap in terms of child access to clean and secure water sources for basic human development needs. The human security paradigm provides a legal and humanitarian foundation for the extension of child rights related to water and sanitation. PMID:22773100

    In rural Uasin Gishu District in 1990, 78.2% of the households had pit latrines, 11.3% ventilated improved pit latrines, 0.8% water-borne and 9.7% with no toilet facilities. On inspection, 97% of the toilet facilities were in use. Compost pits were present in 52.3% of the households. Utensil drying racks were found in 56.0% of the households. Compared to previous estimates, these levels represent a tremendous improvement in sanitation service coverage. It is recommended that the impact of water and sanitation programmes on health status needs to be evaluated. There is a need for studies to be done on the value of utensil drying racks in disease control. PMID:1298615

    Following the discovery of mosquito transmission of malaria, the theory and practice of malaria control by general and selective removal of specific vector populations resulted particularly from Malcolm Watson's empirical work in peninsular Malaysia, first in the urban and peri-urban areas of Klang and Port Swettenham and subsequently in the rural rubber plantations, and from the work of N.H. Swellengrebel in nearby Indonesia on the taxonomy, ecology and control of anophelines. They developed the concept of species sanitation: the selective modification of the environment to render a particular anopheline of no importance as a vector in a particular situation. The lack of progress along these lines in India at that time is contrasted with that in south-east Asia. The extension of species sanitation and related concepts to other geographical areas and to other vector-borne disease situations is outlined. PMID:7898951

    In adoption decisions for decentralized sanitation technologies, two decision makers are involved: the public utility and the individual homeowner. Standard life cycle cost is calculated from the perspective of the utility, which uses a market-based discount rate in these calculations. However, both decision-makers must be considered, including their differing perceptions of the time trade-offs inherent in a stream of costs and benefits. This study uses the discount rate as a proxy for these perceptions and decision-maker preferences. The results in two case studies emphasize the dependence on location of such analyses. Falmouth, Massachusetts, appears to be a good candidate for incentivizing decentralized sanitation while the Allegheny County Sanitary Authority service area in Pennsylvania appears to have no need for similar incentives. This method can be applied to any two-party decision in which the parties are expected to have different discount rates. PMID:27183382

    Building toilets and getting people to use them is critical for public health. We deployed a political ecology approach specifically to identify the multi-scalar political, economic, and environmental factors influencing toilet adoption in rural India. The research used ethnographic and technical methods in rural villages of West Bengal and Himachal Pradesh over the period September 2012 to May 2013. The elements of successful sanitation adoption depended on three factors (i.e., toilet tripod): (1) multi-scalar political will on the part of both government and NGOs over the long term; (2) proximate social pressure, i.e., person-to-person contact between rural inhabitants and toilets; (3) political ecology, i.e., assured access to water, compatible soil type, and changing land use. This research contributes to studies of sustainable development and global public health by developing a theory and framework for successful sanitation. PMID:24954614

    The present study aimed to determine the effectiveness of propolis in reducing the microbial load in ready-to-eat (RTE) and fresh whole head (FWH) lettuces (Lactuca sativa L.) type Batavia. Two sanitizing solutions were employed: sodium hypochlorite (SH) and propolis (PS), during 15 and 30 min. Tap water (TW) was used as a control. Regarding the mean reduction on aerobic mesophiles, psychrotrophic and fecal coliforms, the SH and PS treatments showed the same pattern of variation. In all cases, PS was slightly more effective in the microbiological reduction in comparison with commercial SH. Reductions between two and three log cycles were obtained with PS on aerobic mesophiles and psychrotrophic counts. The information obtained in the present study can be used to evaluate the potential use of propolis as product for sanitizing other vegetables and for developing other food preservation technologies, with impact on human health.

To date, 72 hand and 19 facial transplantations have been performed worldwide. VCA in hand and facial transplantation is a complex procedure requiring a multidisciplinary team approach and extensive surgical planning. Despite good functional outcome, courses after hand and facial transplantation have been complicated by skin rejection. Long-term immunosuppression remains a necessity in VCA for allograft survival. To widen the scope of these quality-of-life-improving procedures, minimization of immunosuppression to limit risks and side effects is needed. PMID:24478387

    Funds to promote access to water and sanitation in developing countries are scarce and most of the investments come from the national governments and households sources, not international resources. In many of these countries, mainly in middle income countries, households are paying direct taxes to access these services, and understanding what determines their choice and motivation is fundamental to promote access to them. It has been argued that is not enough to supply a wide range of alternatives unless the individuals can recognise their benefits and sustainability. The objective of this paper is to understand the choice of sanitation technology by residents in the city of Salvador, Brazil. We propose a unique hybrid choice model that incorporates a set of latent attitudinal variables and explains how the demographic factors within a household influence choice. The substantial difference of our hybrid choice model from descriptive frameworks is that it integrates choice and latent variables (such as attitudes and preferences) allowing us to model explicitly the cognitive process that influences sanitation adoption, draw conclusions from cognitive variables associated with individuals' socio-economic and demographic characteristics, and establishes a causal pathway among these variables. The results show that the attributes of health protection, accessibility, privacy, and house modernisation were what households cared about when opting for flush toilet and sewerage connection, rather than the high cost and consequent household socio-economic status associated with them. The hybrid model is statistically consistent with these findings, and seems to fill the gap between behavioural theory and discrete choice models applied to sanitation. PMID:21439700

    Fixation techniques preserving morphological fidelity, protein antigenicity and integrity of nucleic acids can have a high impact on both basic and applied biomedical sciences and diagnostic pathology. Different types of mouse tissues were fixed with neutral buffered formalin, ethanol supplemented with acetic acid and modified methacarn (methanol-Carnoy) fixative. The alcohol-fixed samples were processed in an Autotechnicon tissue processor or in an incubator. The preservation of tissue morphology was assessed in all specimens and the immunoreactivity was evaluated with antibodies specific for proteins with nuclear, membrane or cytoplasmic localization. RNA was extracted from all groups of fixed hind limb skeletal muscle specimens and was assessed versus unfixed tissue for preservation of its quantity and quality by amplification of gene-specific fragments of different lengths. Both alcohol-based fixatives preserved the tissue architecture and the specificity of immunoreactivity in excellent quality; the trimming approach did not result in detectable differences. Oligonucleotide fragments of length between 108 and 577 base pairs were amplified from all groups of alcohol-fixed skeletal muscle specimens in amounts comparative to the unfixed muscle tissue. We conclude that both alcohol-based fixatives are an excellent tool for storage of tissue samples designed for immunohistochemical and mRNA expression studies when the access to fresh samples is limited.

    In this paper, a focusing reflectarray based on the conductor-backed strip dipole unit cell is proposed and designed for use in the microwave virus sanitizer. Unlike traditional far-field antennas that form a planar phase front in a specified far-field direction, the focusing reflectarray is designed to coherently add the fields radiated from the feeding antenna at a predetermined focal point, typically within its radiating near-field region and to ensure adequate power density to inactivate the H3N2 virus sample. Furthermore, the focusing reflectarray has a simple and planar structure compared with conventional focusing antennas. Since the microwave resonant absorption frequency of the H3N2 virus is at about 8 GHz, an 8 × 8 focusing reflectarray is designed for operation at 8 GHz. A prototype antenna is then fabricated and used for H3N2 virus sanitization. It is demonstrated experimentally that the death rate of the H3N2 virus sample is up to 93%, verifying the feasibility of the microwave virus sanitizer as well as the proposed focusing reflectarray.

    Background Ever since John Snow’s intervention on the Broad St pump, the effect of water quality, hygiene and sanitation in preventing diarrhoea deaths has always been debated. The evidence identified in previous reviews is of variable quality, and mostly relates to morbidity rather than mortality. Methods We drew on three systematic reviews, two of them for the Cochrane Collaboration, focussed on the effect of handwashing with soap on diarrhoea, of water quality improvement and of excreta disposal, respectively. The estimated effect on diarrhoea mortality was determined by applying the rules adopted for this supplement, where appropriate. Results The striking effect of handwashing with soap is consistent across various study designs and pathogens, though it depends on access to water. The effect of water treatment appears similarly large, but is not found in few blinded studies, suggesting that it may be partly due to the placebo effect. There is very little rigorous evidence for the health benefit of sanitation; four intervention studies were eventually identified, though they were all quasi-randomized, had morbidity as the outcome, and were in Chinese. Conclusion We propose diarrhoea risk reductions of 48, 17 and 36%, associated respectively, with handwashing with soap, improved water quality and excreta disposal as the estimates of effect for the LiST model. Most of the evidence is of poor quality. More trials are needed, but the evidence is nonetheless strong enough to support the provision of water supply, sanitation and hygiene for all. PMID:20348121

    Sensor based, computer controlled end effectors for mechanical arms are receiving more and more attention in the robotics industry, because commonly available grippers are only adequate for simple pick and place tasks. This paper describes the current status of the research at JPL on a smart hand for a Puma 560 robot arm. The hand is a self contained, autonomous system, capable of executing high level commands from a supervisory computer. The mechanism consists of parallel fingers, powered by a DC motor, and controlled by a microprocessor embedded in the hand housing. Special sensors are integrated in the hand for measuring the grasp force of the fingers, and for measuring forces and torques applied between the arm and the surrounding environment. Fingers can be exercised under position, velocity and force control modes. The single-chip microcomputer in the hand executes the tasks of communication, data acquisition and sensor based motor control, with a sample cycle of 2 ms and a transmission rate of 9600 baud. The smart hand described in this paper represents a new development in the area of end effector design because of its multi-functionality and autonomy. It will also be a versatile test bed for experimenting with advanced control schemes for dexterous manipulation.

    Emerging evidence demonstrates how inadequate access to water and sanitation is linked to psychosocial stress, especially among women, forcing them to navigate social and physical barriers during their daily sanitation routines. We examine sanitation-related psychosocial stress (SRPS) across women's reproductive lives in three distinct geographic sites (urban slums, rural villages, and rural tribal villages) in Odisha, India. We explored daily sanitation practices of adolescent, newly married, pregnant, and established adult women (n = 60) and identified stressors encountered during sanitation. Responding to structured data collection methods, women ranked seven sanitation activities (defecation, urination, menstruation, bathing, post-defecation cleaning, carrying water, and changing clothes) based on stress (high to low) and level of freedom (associated with greatest freedom to having the most restrictions). Women then identified common stressors they encountered when practicing sanitation and sorted stressors in constrained piles based on frequency and severity of each issue. The constellation of factors influencing SRPS varies by life stage and location. Overall, sanitation behaviors that were most restricted (i.e., menstruation) were the most stressful. Women in different sites encountered different stressors, and the level of perceived severity varied based on site and life stage. Understanding the influence of place and life stage on SRPS provides a nuanced understanding of sanitation, and may help identify areas for intervention. PMID:26551866

    Emerging evidence demonstrates how inadequate access to water and sanitation is linked to psychosocial stress, especially among women, forcing them to navigate social and physical barriers during their daily sanitation routines. We examine sanitation-related psychosocial stress (SRPS) across women’s reproductive lives in three distinct geographic sites (urban slums, rural villages, and rural tribal villages) in Odisha, India. We explored daily sanitation practices of adolescent, newly married, pregnant, and established adult women (n = 60) and identified stressors encountered during sanitation. Responding to structured data collection methods, women ranked seven sanitation activities (defecation, urination, menstruation, bathing, post-defecation cleaning, carrying water, and changing clothes) based on stress (high to low) and level of freedom (associated with greatest freedom to having the most restrictions). Women then identified common stressors they encountered when practicing sanitation and sorted stressors in constrained piles based on frequency and severity of each issue.

    Acid anionic sanitizers for treatment of fruits and vegetables were prepared using ingredients generally recognized as safe by the U.S. Food and Drug Administration or anionic surfactants and organic acid food additives. They met the regulatory definition as sanitizers by showing bactericidal efficacy of 99.999% in 30 s against Staphylococcus aureus ATCC 6538 and Escherichia coli ATCC 11229. These sanitizers showed a broad spectrum of microbicidal activity against both gram-positive and gram-negative bacteria. Antibiotic-sensitive and resistant strains of Listeria monocytogenes and Salmonella typhimurium were equally susceptible to these sanitizers. The acid anionic sanitizers showed microbicidal efficacy equal to that of hypochlorite against Aeromonas hydrophila, E. coli O157:H7, L. monocytogenes, Pseudomonas aeruginosa, S. typhimurium, and S. aureus. Unlike most other sanitizers, these agents do not covalently react with organic components of food; unlike cationic agents, they do not leave residues. The acid anionic sanitizers are prepared using stable, biodegradable, and nontoxic ingredients. Rapid microbicidal activity and the ease of storage, transportation, and use make these sanitizers an attractive alternative to hypochlorite for sanitizing fruits and vegetables. PMID:9798163

    Questions surrounding the origin and early evolution of primates continue to be the subject of debate. Though anatomy of the skull and inferred dietary shifts are often the focus, detailed studies of postcrania and inferred locomotor capabilities can also provide crucial data that advance understanding of transitions in early primate evolution. In particular, the hand skeleton includes characteristics thought to reflect foraging, locomotion, and posture. Here we review what is known about the early evolution of primate hands from a comparative perspective that incorporates data from the fossil record. Additionally, we provide new comparative data and documentation of skeletal morphology for Paleogene plesiadapiforms, notharctines, cercamoniines, adapines, and omomyiforms. Finally, we discuss implications of these data for understanding locomotor transitions during the origin and early evolutionary history of primates. Known plesiadapiform species cannot be differentiated from extant primates based on either intrinsic hand proportions or hand-to-body size proportions. Nonetheless, the presence of claws and a different metacarpophalangeal [corrected] joint form in plesiadapiforms indicate different grasping mechanics. Notharctines and cercamoniines have intrinsic hand proportions with extremely elongated proximal phalanges and digit rays relative to metacarpals, resembling tarsiers and galagos. But their hand-to-body size proportions are typical of many extant primates (unlike those of tarsiers, and possibly Teilhardina, which have extremely large hands). Non-adapine adapiforms and omomyids exhibit additional carpal features suggesting more limited dorsiflexion, greater ulnar deviation, and a more habitually divergent pollex than observed plesiadapiforms. Together, features differentiating adapiforms and omomyiforms from plesiadapiforms indicate increased reliance on vertical prehensile-clinging and grasp-leaping, possibly in combination with predatory behaviors in

    In this study, the antimicrobial efficacy of hand washing (HW) and hand washing plus rubbing with an alcohol-based solution (HWR) on numbers of total and transient flora colonies on the hands of healthcare workers (HCWs) during routine patient care was assessed. Samples were collected, using a standard bag broth technique, from the hands of 154 HCWs, before and immediately after carrying out a hand hygiene procedure. The numbers of total and transient flora colonies per plate were counted and transient pathogens were identified. A significant statistical difference between ward speciality was detected with respect to the isolation rate of transient flora. Transient hand flora were recovered from 25.3% of HCWs before carrying out the hand hygiene procedure. With respect to the disappearance and prevention of regrowth of transient flora after hand hygiene, the HWR technique was significantly more effective than HW. In conclusion, a disinfectant should be added to the hand washing process to achieve optimum protection against nosocomial infections in routine hospital practice. PMID:21227014

    This study investigated residual bacteria and different food types left on tableware items after various washing and sanitization protocols. Escherichia coli K-12 and Staphylococcus epidermidis were inoculated into whole milk and soft cream cheese. The milk was used to contaminate regular drinking glasses and the cheese was used to contaminate plates and silverware. These tableware items were washed in manual (43 degrees C) and mechanical (49 degrees C) washers and sanitized with different sanitizers (24 degrees C) for 5 s. Quaternary ammonium compound, sodium hypochlorite, peroxyacetic acid, neutral electrolyzed water (NEW), and a combination of citric acid with sodium dodecylbenzene sulfonate (acidic formulation) were used as the chemical sanitizers. Tap water was used as a control. Results showed that at least 5-log reductions in both bacterial numbers were achieved for all sanitizers in both types of washers, except for the control. With mechanical dishwashing, the NEW and acidic formulation treatments reduced bacterial populations by >6.9 and >6.0 log CFU per tableware item, respectively. With the manual operation, bacterial numbers were reduced by >5.4 and >6.0 log CFU per tableware item, respectively. This study revealed that NEW and the acidic formulation are as effective as the other chemical sanitizers for food contact surface sanitization in manual and mechanical ware washing. PMID:19610348

    Background Health care associated infections are more predominant in developing countries where Hand hygiene compliance is associated with so many factors. However, these factors have not been studied so far in the study area. This study sought to determine Hand hygiene compliance and associated factors among health care providers. Methods Institution based cross-sectional study was conducted from April to May, 2013 in Gondar University Hospital. Stratified sampling technique was used to select 405 health care providers. Standardized questionnaire and world health organization observational checklist was used to collect the data. Data was entered and analyzed by using SPSS version 20. Descriptive statistics and binary logistic regression model was used to summarize the result. Results A total of 405 study participants were interviewed and observed with a response rate of 96.4%. Good Hand hygiene compliance of healthcare providers was found to be 16.5%. Having knowledge about hand hygiene compliance, (AOR = 3.80, 95% CI 1.60, 8.97), getting training (AOR = 2.60, 95% Cl 1.21, 5.62), the presence of individual towel/tissue paper (AOR = 1.91, 95% CI 1.03, 3.56) presence of alcohol based hand rub for Hand hygiene compliance (AOR = 6.58, 95% CI 2.67, 16.22) and knew the presence of infection prevention committees (AOR = 2.6, 95% CI 1.23, 5.37) were significantly associated with hand hygiene compliance. Conclusions Hand hygiene compliance among health care providers in Gondar University Hospital was found to be low. It is better to give training on Hand hygiene compliance and provide Alcohol based hand rub and individual towel or tissue paper for hand hygiene compliance. PMID:24479696

    Produce safety has received much recent attention, with the emphasis being largely on discovery of how microbes invade produce. However, the sanitization operation deserves more attention than it has received. The ability of a sanitizer to reach the site of pathogens is a fundamental prerequisite for efficacy. This work addresses the transport processes of ozone (gaseous and liquid) sanitizer for decontamination of leafy greens. The liquid sanitizer was ineffective against Escherichia coli K-12 in situations where air bubbles may be trapped within cavities. A model was developed for diffusion of sanitizer into the interior of produce. The reaction rate of ozone with the surface of a lettuce leaf was determined experimentally and was used in a numerical simulation to evaluate ozone concentrations within the produce and to determine the time required to reach different locations. For aqueous ozone, the penetration depth was limited to several millimeters by ozone self-decomposition due to the significant time required for diffusion. In contrast, gaseous sanitizer was able to reach a depth of 100 mm in several minutes without depletion in the absence of reaction with surfaces. However, when the ozone gas reacted with the produce surface, gas concentration was significantly affected. Simulation data were validated experimentally by measuring ozone concentrations at the bottom of a cylinder made of lettuce leaf. The microbiological test confirmed the relationship between ozone transport, its self-decomposition, reaction with surrounding materials, and the degree of inactivation of E. coli K-12. Our study shows that decontamination of fresh produce, through direct contact with the sanitizer, is more feasible with gaseous than with aqueous sanitizers. Therefore, sanitization during a high-speed washing process is effective only for decontaminating the wash water. PMID:26613904

    Hand washing is considered as the single most important strategy to prevent infections. World health organization (WHO) defines hand hygiene as a primary issue of personal care with particular reference to hospital personnel and health facility workers. In this work, we investigated a new combination for hand disinfection as an alternative to alcohol-based and chlorhexidine products. The new combination of 5-pyrrolidone-2-carboxylic acid (PCA) and copper sulphate pentahydrate (CS) was tested upon different bacterial species that normally colonize hands, including Staphylococcus aureus, methicillin resistant S. aureus (MR S. aureus), Staphylococcus epidermidis, multidrug resistant S. epidermidis (MDR S. epidermidis), Streptococcus pyogenes, Streptococcus agalactiae, Escherichia coli, Candida albicans and three clinical isolates: MR S. aureus, MDR S. epidermidis, and an E. coli strain. Minimal inhibitory concentrations (MICs), Minimal bactericidal concentrations (MBCs), fractional inhibitory concentration (FIC) indices, and fractional bactericidal concentration (FBC) indices were evaluated. Ethanol 70% V/V, isopropanol 60% V/V, and 4% w/V chlorhexidine solution were used as reference hand disinfectants. Copper sulphate pentahydrate was very effective against all tested microorganisms: The MIC and MBC for CS ranged from 781 mg/l against S. pyogenes to 12500 mg/l against E. coli strains and C. albicans. In addition, PCA exhibited a good antimicrobial activity, in particular, against S. pyogenes and S. agalactiae. The combination of CS and PCA showed a strong synergistic effect and all FIC indices were ≤0·500. The combination of CS and PCA were more effective than ethanol 70% V/V and isopropanol 60% V/V. In addition to antimicrobial activity, the new formulation possesses peculiar features such as residual activity and moisturizing effect. This work identifies a new strategy for hand disinfection.

    Hand hygiene of healthcare workers is frequently poor despite the efforts of infection control teams to promote hand decontamination as the most important method to prevent transmission of hospital-acquired infections. In this case study, we describe how principles of societal marketing were applied to improve hand hygiene. Pre-marketing analysis of strengths, weaknesses, opportunities and threats to implementation; attention to product, price, promotion and placement; and post-marketing 'customer' surveys were the essential components of the marketing strategy and its implementation. Placement of an alcohol-based gel decontaminant (Spirigel) at the bedside of every patient was widely welcomed in the hospital, and has played a major role in improving hand hygiene of healthcare workers. In the twelve months following the implementation, the decontaminant was used at least 440,000 times. The cost of purchasing the decontaminant was approximately 5000 pounds sterling. Following the introduction of Spirigel, there was a consistent reduction in the proportion of hospital-acquired methicillin-resistant Staphylococcus aureus (MRSA) in each of the quarters of 2000-2001 compared with 1999-2000. In the period 1999-2000, nearly 50% of the MRSA were hospital acquired compared with 39% in 2000-2001. Similarly, the average incidence of Clostridium difficile associated diarrhoea (CDAD) decreased in each of the quarters in 2000-2001 following the introduction of Spirigel. During this period, there was an average incidence of 9.5 cases of CDAD/1000 admissions compared with 11.5 cases of CDAD/1000 admissions in 1999-2000. This represents a 17.4% reduction in the incidence of CDAD. However, this reduction was not statistically significant (P=0.2). Our case study demonstrates that principles of societal marketing methods can be used effectively to promote and sustain hand hygiene in hospitals. Improvement in hand hygiene will lead to considerable reduction in hospital

    An automatic, personnel-operated, alpha-particle hand monitor is described which functions as a qualitative instrument to indicate to the person using it whether his hands are cold'' or hot.'' The monitor is activated by a push button and includes several capacitor-triggered thyratron tubes. Upon release of the push button, the monitor starts the counting of the radiation present on the hands of the person. If the count of the radiation exceeds a predetermined level within a predetermined time, then a capacitor will trigger a first thyratron tube to light a hot'' lamp. If, however, the count is below such level during this time period, another capacitor will fire a second thyratron to light a safe'' lamp. (AEC)

    2014-01-01

    Background While the sanitation ladder is useful in analysing progressive improvements in sanitation, studies in Uganda have not indicated the sanitation barriers faced by the urban poor. There are various challenges in shared latrine use, cleaning and maintenance. Results from Kampala city indicate that, failure to clean and maintain sanitation infrastructure can lead to a reversal of the potential benefits that come with various sanitation facilities. Methods A cross sectional qualitative study was conducted between March and May 2013. Data were collected through 18 focus group discussions (FGDs) held separately; one with women, men and youth respectively. We also used pictorial methods; in addition, 16 key informant interviews were conducted. Data were analysed using content thematic approach. Relevant quotations per thematic area were identified and have been used in the presentation of the results. Results Whether a shared sanitation facility was improved or not, it was abandoned once it was not properly used and cleaned. The problem of using shared latrines began with the lack of proper latrine training when people do not know how to squat on the latrine hole. The constrained access and security concerns, obscure paths that were filthy especially at night, lack of light in the latrine cubicle, raised latrines sometimes up to two metres above the ground, coupled with lack of cleaning and emptying the shared facilities only made a bad situation worse. In this way, open defecation gradually substituted use of the available sanitation facilities. This paper argues that, filthy latrines have the same net effect as crude open defection. Conclusion Whereas most sanitation campaigns are geared towards provision of improved sanitation infrastructure, these findings show that mere provision of infrastructure (improved or not) without adequate emphasis on proper use, cleaning and maintenance triggers an involuntary descent off the sanitation ladder.

This investigation included 221 hand injuries. The sex distribution shows a general male dominance (85.25%) in their active age (84.44%). These are, seasonal injuries mostly occurring in October (75.11%). By type of injuries, mutilating crush injuries are most frequent (64.25%). After completing the treatment, in most cases the functional result were estimated as bad (50.68%). Data concerning education and trainig for operating agricultural machines (96.38%--patients without training) and carrying out safety measures (63.35% of injured patients did not apply any protection measures) are devastating. The number of these injuries, as well as consequent permanent disabilities, may be considerably reduced by preventive measures, inclulding public health services and media. Use of contempoarary agricultural machinery, as well as obligatory training for operating these machines and application of protective measures, may also reduce the incidence of hand injuries during corn picking.

    Improved sanitation is considered equally important for public health as is access to improved drinking water. However, the world has been slower to meet the challenge of sanitation provision for the world's poor. We analyze previously cited barriers to sanitation coverage including inadequate investment poor or nonexistent policies, governance, too few resources, gender disparities, and water availability. Analysis includes investigation of correlation between indicators of the mentioned barriers and sanitation coverage, correlations among the indicators themselves, and a geospatial assessment of the potential impacts of sanitation technology on global water resources under six scenarios of sanitation technology choice. The challenges studied were found to be significant barriers to sanitation coverage, but water availability was not a primary obstacle at a global scale. Analysis at a 0.5 degrees grid scale shows, however, that water availability is an important barrier to as many as 46 million people, depending on the sanitation technology selected. The majority of these people are urban dwellers in countries where water quality is already poor and may be further degraded by sewering vast populations. Water quality is especially important because this vulnerable population primarily resides in locations that depend on environmental income associated with fish consumption. PMID:18605547

    Application of nonfouling coatings on thermal processing equipment can improve operational efficiency. However, to enable effective commercial translation, a need exists for more comprehensive studies on the stability of nonfouling coatings after exposure to different sanitizers. In the current study, the influence of different commercial dairy equipment sanitizers on the nonfouling properties of stainless steel modified with electroless Ni-polytetrafluoroethylene (PTFE) coatings was determined. Surface properties, such as dynamic contact angle, surface energy, surface morphology, and elemental composition, were measured before and after the coupons were exposed to the sanitizers for 168 cleaning cycles. The fouling behavior of Ni-PTFE-modified stainless steel coupons after exposure was also evaluated by processing raw milk on a self-fabricated benchtop-scale plate heat exchanger. The results indicated that peroxide sanitizer had only minor effect on the Ni-PTFE-modified stainless steel surface, whereas chlorine- and iodine-based sanitizers influenced the surface properties drastically. The coupons after 168 cycles of exposure to peroxide sanitizer accumulated the least amount of fouling material (4.44±0.24mg/cm(2)) compared with the coupons exposed to the other 3 sanitizers. These observations indicated that the Ni-PTFE nonfouling coating retained antifouling properties after 168 cycles of exposure to peroxide-based sanitizer, supporting their potential application as nonfouling coatings for stainless steel dairy processing equipment.

    Numerous antimicrobial chemicals are currently utilized as processing aids with the aim of reducing pathogenic bacteria on processed poultry carcasses. Carryover of active sanitizer to a carcass rinse solution intended for recovery of viable pathogenic bacteria by regulatory agencies may cause false-negative results. This study was conducted to document the potential carryover effect of five sanitizing chemicals commonly used as poultry processing aids for broilers in a postchill dip. The effect of postdip drip time on the volume of sanitizer solution carryover was first determined by regression of data obtained from 10 carcasses. The five sanitizer solutions were diluted with buffered peptone water at 0-, 1-, and 5-min drip time equivalent volumes as determined by the regression analysis. These solutions were then spiked to 10(5) CFU/ml with a mixture of five nalidixic acid-resistant Salmonella enterica serovars, stored at 4°C for 24 h, and finally enumerated by plate count on brilliant green sulfa agar containing nalidixic acid. At the 0- and 1-min drip time equivalents, no Salmonella recovery was observed in three of the five sanitizers studied. At the 5-min drip time equivalent, one of these sanitizers still exhibited significant (P ≤ 0.05) bactericidal activity. These findings potentially indicate that the currently utilized protocol for the recovery of Salmonella bacteria from postchill sanitizer interventions may lead to false-negative results due to sanitizer carryover into the carcass rinsate.

    In two villages of Bangladesh, 2471 infants born in 1976 and 1977 were followed up for a year to study the impact of environmental sanitation and crowding on their mortality. Neonatal and postneonatal mortality rates in the study cohort were 100 and 75 per 1000 live-births, respectively. Multiple logistic regression analysis was done to estimate the effects of the selected risk factors while controlling for some socioeconomic, demographic, and biological characteristics. Risk of postneonatal mortality (PNNM) in the households which did not use latrines was 3 X 12 times (p less than 0.01) higher than in those which did and 1.5 times (p less than 0.05) higher in the households with 10 or more persons than in smaller households. PNNM in the households which did not use tube-wells (hand-pump) water was higher, but not significantly so, than in those which used tube-well water for all purposes. Neonatal mortality was completely unrelated to the environmental factors investigated. PMID:2861464

    Purpose. This review was done to explore the impact of water treatment, hygiene, and sanitary interventions on improving child health outcomes such as absenteeism, infections, knowledge, attitudes, and practices and adoption of point-of-use water treatment. Methods. A literature search was conducted using the databases PubMed and Google scholar for studies published between 2009 and 2012 and focusing on the effects of access to safe water, hand washing facilities, and hygiene education among school-age children. Studies included were those that documented the provision of water and sanitation in schools for children less than 18 years of age, interventions which assessed WASH practices, and English-language, full-text peer reviewed papers. Results. Fifteen studies were included in the final analysis. 73% (n = 11) of the studies were conducted in developing countries and were rural based (53%, n = 8). The child's age, gender, grade level, socioeconomic index, access to hygiene and sanitary facilities, and prior knowledge of hygiene practices were significantly associated with the outcomes. Nutrition practices which are key factors associated with the outcomes were rarely assessed. Conclusion. Further research is required to assess the long-term impact of such interventions in different settings. PMID:24454415

    Introduction Water related diseases constitute a significant proportion of the burden of disease in Kenya. Water, sanitation and hygiene (WASH) programs are in operation nation-wide to address these challenges. This study evaluated the impact of the Sombeza Water and Sanitation Improvement Program (SWASIP) in Coast Province, Kenya. Methods This study is a cluster randomized, follow-up evaluation that compared baseline (2007) to follow-up (2013) indicators from 250 households. Twenty-five villages were selected with probability proportional to size sampling, and ten households were selected randomly from each village. Follow-up data were collected by in-person interviews using pre-tested questionnaires, and analyzed to compare indicators collected at baseline. Cross-sectional results from the follow-up data were also reported. Results Statistically significant improvements from baseline were observed in the proportions of respondents with latrine access at home, who washed their hands after defecation, who treated their household drinking water and the average time to collect water in the dry season. However, this study also observed significant decreases in the proportion of respondents who washed their hands before preparing their food, or feeding their children, and after attending to a child who has defecated. The analysis also revealed a knowledge-behavior gap in WASH behaviors. Conclusion SWASIP contributed to improvements from baseline, but further progress still needs to be seen. The findings challenge the assumption that providing infrastructure and knowledge will result in behavior change. Further understanding of specific, non-knowledge predictors of WASH related behavior is needed. PMID:27279970

    Like most cities in developing countries, Kigali is experiencing rapid urbanisation leading to an increase in the urban population and rapid growth in the size and number of informal settlements. More than 60% of the city’s population resides in these settlements, where they experience inadequate and poor quality urban services including sanitation. This article discusses the issues and constraints related to the provision of sustainable sanitation in the informal settlements in Kigali. Two informal settlements (Gatsata and Kimisagara) were selected for the study, which used a mixed method approach for data collection. The research found that residents experienced multiple problems because of poor sanitation and that the main barrier to improved sanitation was cost. Findings from this study can be used by the city authorities in the planning of effective sanitation intervention strategies for communities in informal settlements. PMID:24336021

    Although the hands age at the same rate as the face, the aging process differs and requires a combination treatment approach for optimal rejuvenation. Photoaging causes epidermal changes such as lentigines, actinic keratoses, fine wrinkles, and crepe-like textural change. Thinning of the dermis and subcutaneous fat occurs as a result of both ultraviolet light exposure and intrinsic aging. This process can lead to a skeletal appearance of the hands, with prominent veins and bulging tendons. The combination approach addresses all of these issues, employing lasers, intense pulsed light devices, fractional devices, fillers, peels, vein sclerotherapy, and an effective at-home skin care program as indicated for individual needs and concerns.

    Any adult with diabetes in the tropics with hand cellulitis, infection and gangrene qualifies for tropical diabetic hand syndrome (TDHS). We reviewed a 39-year-old woman with a 3-week history of swelling of the left index finger following an insect bite. The swelling progressively increased in size, was very painful, and extended to the palm. There was no history or symptoms suggestive of chronic complications of diabetes. Random blood sugar on presentation was above 600 mg/dl using a glucometer. Examination revealed an edematous left palm draining pus from multiple sinuses, necrotic and gangrenous left index finger extending down to just above the thenar eminence. A diagnosis of TDHS in a patient with hyperosmolar state was made. She was managed accordingly and subsequently underwent aggressive debridement and desloughing. Two fingers were amputated and the wound was allowed to heal by secondary intention. PMID:27057390

    2016-08-01

    Alien hand syndrome (AHS) is a rare disorder of involuntary limb movement together with a sense of loss of limb ownership. It most commonly affects the hand, but can occur in the leg. The anterior (frontal, callosal) and posterior variants are recognized, with distinguishing clinical features and anatomical lesions. Initial descriptions were attributed to stroke and neurosurgical operations, but neurodegenerative causes are now recognized as most common. Structural and functional imaging and clinical studies have implicated the supplementary motor area, pre-supplementary motor area, and their network connections in the frontal variant of AHS, and the inferior parietal lobule and connections in the posterior variant. Several theories are proposed to explain the pathophysiology. Herein, we review the literature to update advances in the understanding of the classification, pathophysiology, etiology, and treatment of AHS. PMID:27315251

    Diacetyl is used to impart a buttery flavor to numerous food products such as sour cream, cottage cheese, vegetable oil-based spreads, baked goods, and beverages. Recent studies have linked exposure to high concentrations of diacetyl and the onset of bronchiolitis obliterans. Due to the reported risks that diacetyl may pose, many food companies have altered practices to reduce worker exposure to diacetyl, including the use of personal respirators, improved air handling systems, and adequate cleaning practices. Commonly used cleaning and sanitizing agents may be reactive with diacetyl; however, the efficacy of these chemicals has not been studied in detail and remains unclear. The objective of this work was to study the reaction chemistry of diacetyl with common industrial cleaning and sanitizing chemicals. The reactions were assessed at equimolar concentrations and analyzed by gas chromatography-mass spectrometry. Peroxyacetic acid was most reactive with diacetyl (95% reduction in diacetyl), followed by sodium hypochlorite (76% reduction), and hydrogen peroxide (26% reduction). Benzalkonium chloride (BAC) did not react with diacetyl. Acetic acid was detected as the main product of reactions of diacetyl with peroxyacetic acid, sodium hypochlorite, and hydrogen peroxide. 1,1-Dichloro-2-propanone and 1,1,1-trichloropropanone were also identified as volatile reaction products in the sodium hypochlorite reactions.

    This study assesses the role of participatory development programmes in improving sanitation in rural Bangladesh. Data for this study came from a health surveillance system of BRAC covering 70 villages in 10 regions of the country. In-depth interviews were conducted with one adult member of a total of 1556 randomly selected households that provided basic socioeconomic information on the households and their involvement with NGO-led development programmes in the community. The findings reveal that households involved with credit programmes were more likely to use safe latrines than others who were equally poor but not involved in such programmes. The study indicates that an unmet need to build or buy safe and hygienic latrines existed among those who did not own one. Such latent need could be raised further if health education at the grassroots level along with supervised credit supports were provided to them. Unlike conventional belief, the concept of community-managed jointly owned latrines did not seem a very attractive alternative. The study argues that social and behavioural aspects of the participatory development programmes can significantly improve environmental sanitation in a traditional community. PMID:11012409

    China is undergoing rapid urbanization and economic development. This requires a new approach on spatial planning and environmental infrastructure. In the presented project an example of this approach is given for the city of Changzhou (China) where a new residential area (Qinglong district) will be developed for 100.000 inhabitants. Key issue within the formulation of sustainable sanitation concepts is the integration and management of water, waste and energy in such a way that they will become beneficial to the establishment of the envisaged green city. Starting point was the closing of material cycles focusing on possibilities to recover and reuse valuable resources and energy from "waste" produced in an urban setting. Four different scenarios focusing on water, nutrient and energy recovery were compared with the baseline wastewater management practice. Besides environmental benefits, the economical benefits of sustainable sanitation concepts are attractive, the break even point with the baseline scenario, is already after 5 years, provided that recovered resources will be sold for a marketable price. We believe that presented concepts are applicable for a wide range of new urban development initiatives in China and similar rapidly developing densely populated regions worldwide. PMID:19955640

    Milk processing lines offer a wide variety of microenvironments where a diversity of microorganisms can proliferate. We sampled crevices and junctions where, due to deficient reach by typical sanitizing procedures, bacteria can survive and establish biofilms. The sampling sites were the holding cell, cold storage tank, pasteurizer and storage tank - transfer pump junction. The culturable bacteria that were isolated after the sanitation procedure were predominantly Pseudomonas spp., Serratia spp, Staphylococcus sciuri and Stenotrophomonas maltophilia. We assayed several phenotypic characteristics such as the ability to secrete enzymes and siderophores, as well as the capacity of the strains to form biofilms that might contribute to their survival in a mixed species environment. The Pseudomonas spp. isolates were found to either produce proteases or lecithinases at high levels. Interestingly, protease production showed an inverse correlation with siderophore production. Furthermore, all of the Serratia spp. isolates were strong biofilm formers and spoilage enzymes producers. The organisms identified were not mere contaminants, but also producers of proteins with the potential to lower the quality and shelf-life of milk. In addition, we found that a considerable number of the Serratia and Pseudomonas spp. isolated from the pasteurizer were capable of secreting compounds with antimicrobial properties. PMID:22761957

    The great popularity of physical fitness in modern society has brought many pieces of exercise equipment into our homes for convenience and privacy. This trend has come with an increasing rate of injuries to children who curiously touch moving parts, including treadmill belts. Experience with a recent series of treadmill contact burns to children's hands is described in this article. A retrospective chart review at a tertiary referral center from June 1998 until June 2001 found six children sustaining hand burns from treadmills. The patients' ages at presentation ranged from 15 to 45 months (average of 31 months, three boys and three girls). All injuries occurred in the home while a parent was using the treadmill. Burns involved the palmar aspect of the hand, mostly confined to the fingers, and the severity ranged from partialto full-thickness burns. All patients were initially managed with collagenase and bacitracin zinc/polymyxin B powder dressings to second- and third-degree burns, along with splinting and range-of-motion exercises. Two patients required skin grafting at 2 weeks and 2 months for full-thickness tissue loss and tight joint contracture, respectively. At an average follow-up of 12 months, all patients had full range of motion and no physical limitation. The rate of children injured by exercise equipment is expected to increase. Friction burns to the hands remain a concern, although early recognition and appropriate management are associated with excellent functional outcomes. Protective modification of exercise machines seems to be the best approach to eliminating these injuries. PMID:12867861

    Four consecutive one-month campaigns were organised to promote hand hygiene in Belgian hospitals between 2005 and 2011. The campaigns included a combination of reminders in wards, educational sessions for healthcare workers, promotion of alcohol-based hand rub use, increasing patient awareness, and audits with performance feedback. Prior and after each one month intervention period, the infection control teams measured hand hygiene compliance of healthcare workers by direct observation using a standardised observation roster. A total of 738,367 opportunities for hand hygiene were observed over the four campaigns. Compliance with hand hygiene significantly increased from 49.6% before to 68.6% after the intervention period for the first, from 53.2% to 69.5% for the second, from 58.0% to 69.1% for the third, and from 62.3% to 72.9% for the fourth campaign. The highest compliance rates were consistently observed in paediatric units. Compliance rates were always markedly lower among physicians than nurses. After patient contact and body fluid exposure risk, compliance rates were noticeably higher than before patient contact and performing aseptic procedures. We conclude that repeated countrywide campaigns to promote hand hygiene result in positive long-term outcomes. However, lower compliance rates among physicians compared with nurses, before patient contact, and before performing aseptic procedures remain challenges for future campaigns. PMID:22587957

    Background More than 761 million people rely on shared sanitation facilities. These have historically been excluded from international sanitation targets, regardless of the service level, due to concerns about acceptability, hygiene and access. In connection with a proposed change in such policy, we undertook this review to identify and summarize existing evidence that compares health outcomes associated with shared sanitation versus individual household latrines. Methods and Findings Shared sanitation included any type of facilities intended for the containment of human faeces and used by more than one household, but excluded public facilities. Health outcomes included diarrhoea, helminth infections, enteric fevers, other faecal-oral diseases, trachoma and adverse maternal or birth outcomes. Studies were included regardless of design, location, language or publication status. Studies were assessed for methodological quality using the STROBE guidelines. Twenty-two studies conducted in 21 countries met the inclusion criteria. Studies show a pattern of increased risk of adverse health outcomes associated with shared sanitation compared to individual household latrines. A meta-analysis of 12 studies reporting on diarrhoea found increased odds of disease associated with reliance on shared sanitation (odds ratio (OR) 1.44, 95% CI: 1.18–1.76). Conclusion Evidence to date does not support a change of existing policy of excluding shared sanitation from the definition of improved sanitation used in international monitoring and targets. However, such evidence is limited, does not adequately address likely confounding, and does not identify potentially important distinctions among types of shared facilities. As reliance on shared sanitation is increasing, further research is necessary to determine the circumstances, if any, under which shared sanitation can offer a safe, appropriate and acceptable alternative to individual household latrines.

    An artificial dexterous hand is provided for grasping and manipulating objects. The hand includes left and right thumbs that are operatively connected to an engagement assembly which causes movement of the left and right thumbs. The left thumb has a left thumb base and is movable about three separate first left thumb axes which run through the left thumb base. Correspondingly, the right thumb has a right thumb base and is movable about three separate first right thumb axes which run through the right thumb base. The engagement assembly has a gear assembly which is operatively connected to a motor assembly. Upon actuation by the motor assembly, the gear assembly causes movement of the left and right thumbs about the first left thumb axes and first right thumb axes respectively. The hand can also have a center finger which is operatively connected to the engagement assembly and which is interposed between the left and right thumbs. The finger has a finger base and is movable about two separate first finger axes running through the finger base. Therefore, upon actuation by the motor assembly, the gear assembly will also cause movement of the finger about the first finger axes.

    A compact robotic hand includes a palm housing, a wrist section, and a forearm section. The palm housing supports a plurality of fingers and one or more movable palm members that cooperate with the fingers to grasp and/or release an object. Each flexible finger comprises a plurality of hingedly connected segments, including a proximal segment pivotally connected to the palm housing. The proximal finger segment includes at least one groove defining first and second cam surfaces for engagement with a cable. A plurality of lead screw assemblies each carried by the palm housing are supplied with power from a flexible shaft rotated by an actuator and output linear motion to a cable move a finger. The cable is secured within a respective groove and enables each finger to move between an opened and closed position. A decoupling assembly pivotally connected to a proximal finger segment enables a cable connected thereto to control movement of an intermediate and distal finger segment independent of movement of the proximal finger segment. The dexterous robotic hand closely resembles the function of a human hand yet is light weight and capable of grasping both heavy and light objects with a high degree of precision.

  17. Bacterial contamination of the hands of food handlers as indicator of hand washing efficacy in some convenient food industries in South Africa

    2014-01-01

    Background and Objectives: Hands of ready-to-eat food service employees have been shown to be vectors in the spread of foodborne disease, mainly because of poor personal hygiene and accounting for approximately 97% of food borne illnesses in food service establishments and homes. Our objective was to evaluate the efficacy of hand washing practices and sanitation before commencing work among food handlers in the convenient food industry in Gauteng, South Africa. Methods: A total of 230 samples were collected, involving 100% of the food handlers, in 8 selected convenient food outlets with their main focus on preparing ready-to-eat foods. The workers’ cleaned and disinfected dominant hands were sampled for Total Plate Count (TPC), Staphylococcus aureus and Escherichia coli. Bacteria were isolated and counted using standard methods. Results: The highest bacterial count from the hand samples was 7.4 x 103 cfu.cm-2 and the lowest showed no detectable growth. Although hands with a count of 0 cfu.cm-2 were found in all of the plants, the results indicated that all the plants exceeded the legal limit for food surfaces or hands of < 100 cfu.cm-2 when the average bacterial counts on hands were compared. Sixty percent of the TPC analysed exceeded the legal limit and only 18% of the food handlers had no bacteria detectable on their hands. One sample tested positive for E. coli and S. aureus could not be detected on the hands of any of the food handlers. Conclusion: The study revealed that hand hygiene is unsatisfactory and may have serious implications for public health due to contamination of food from food handlers’ hands. This therefore underlined the importance of further training to improve food handlers’ knowledge of good hand washing practices. PMID:25097511

    Diseases often spread in hospitals because health care professionals fail to wash their hands. Research suggests that to increase health and safety behaviors, it is important to highlight the personal consequences for the actor. However, because people (and health care professionals in particular) tend to be overconfident about personal immunity, the most effective messages about hand hygiene may be those that highlight its consequences for other people. In two field experiments in a hospital, we compared the effectiveness of signs about hand hygiene that emphasized personal safety ("Hand hygiene prevents you from catching diseases") or patient safety ("Hand hygiene prevents patients from catching diseases"). We assessed hand hygiene by measuring the amount of soap and hand-sanitizing gel used from dispensers (Experiment 1) and conducting covert, independent observations of health care professionals' hand-hygiene behaviors (Experiment 2). Results showed that changing a single word in messages motivated meaningful changes in behavior: The hand hygiene of health care professionals increased significantly when they were reminded of the implications for patients but not when they were reminded of the implications for themselves.

    The recent discovery of the bio-waste and excreta treatment of a former civilisation in the Amazon reveals the possibility of a highly efficient and simple sanitation system. With the end product that was black soil they converted 10% of former infertile soil of the region: Terra Preta do Indio (black soil of the Indians). These soils are still very fertile 500 years after this civilisation had disappeared. Deriving from these concepts, Terra Preta Sanitation (TPS) has been re-developed and adopted. TPS includes urine diversion, addition of a charcoal mixture and is based on lactic-acid-fermentation with subsequent vermicomposting. No water, ventilation or external energy is required. Natural formation processes are employed to transform excreta into lasting fertile soil that can be utilised in urban agriculture. The authors studied the lacto-fermentation of faecal matter with a minimum of 4 weeks followed by vermicomposting. The results showed that lactic-acid fermentation with addition of a charcoal mixture is a suitable option for dry toilets as the container can be closed after usage. Hardly any odour occured even after periods of several weeks. Lactic-acid fermentation alone without addition of bulking agents such as paper and sliced-cut wood to raise the C/N ratio is creating a substrate that is not accepted by worms. PMID:20453341

    Lack of basic sanitation systems threaten environmental and human health in low income urban communities. In 2005, the Government of Zimbabwe carried out a cleanup exercise in urban areas involving the destruction of illegal structures which left many people homeless. As a solution to this problem, the government embarked on an extensive housing construction exercise on unserviced land; the ‘Garikai/Hlalani Kuhle’ development programme. The objective of this paper was to investigate the sanitation status in one such area (Cowdray Park Extension, Bulawayo) and determine a sustainable sanitation system for the improved collection of wastewater from the unserviced low income urban area. The study was carried out between October 2010 and February 2011. The sanitation status as well as the residents’ preferences for improved sanitation and the economic set up of the community for the study area was determined through use of questionnaires to the residents. The local authority was then consulted to recommend sanitation facilities and system for the area that met regulatory requirements. A literature study identified sanitation options that were applicable to low income and high density urban areas. The baseline survey found that 61% of the people in the study area lacked sanitation facilities and practiced open defecation. The majority of the residents (70%) preferred ‘flush and discharge’ system sanitation facilities, which was in line with the local council’s requirements. On-site sanitation options were found not to be feasible as per the council regulations and the findings of the literature study, for areas with a high density of houses. Therefore a sewerage system was designed using the conventional sewerage design approach as well as the simplified sewerage design approach in order to determine the collection system that would best meet the needs of the community. In conclusion, the community was in dire need of a sanitation system and a waterborne

    Background Illness-related absences have been shown to lead to negative educational and economic outcomes. Both hand washing and hand sanitizer interventions have been shown to be effective in reducing illness-related absences. However, while the importance of hand hygiene in schools is clear, the role of instruction in use is less obvious. The purpose of this study was to compare absenteeism rates among elementary students given access to hand hygiene facilities versus students given both access and short repetitive instruction in use, particularly during influenza season when illness-related absences are at a peak. Methods A hand hygiene intervention was implemented from October to May during the 2009/2010 academic year, including peak flu season, in two Chicago Public Elementary Schools among students grades pre-kindergarten to eighth grade (ages 4–14). Classrooms were systematically assigned to an intervention or control group by grade (cluster design). Hand hygiene facilities (sanitizer and soap) were made available to all students. Students in the intervention group also received short repetitive instruction in hand hygiene every 2 months. Only absences as a result of respiratory or gastrointestinal illness were used to establish illness-related absenteeism rates. Percent absent days were calculated and bivariate analyses were performed to compare percent absent days among students given access to hand hygiene facilities versus students given both access and instruction. Prior to the intervention, teachers’ perceptions of students’ hand hygiene were also evaluated. Teacher perceptions were analysed to describe attitudes and beliefs. Results Data were collected and analysed for 773 students reporting 1,886 absences during the study period (1.73% of total school days). Both the percent total absent days and percent illness-related absent days were significantly lower in the group receiving short instruction during flu season (P = 0.002, P < 0

    This systematic review aimed to critically appraise and synthesize updated evidence regarding the effect of surgical-scrub techniques on skin integrity and the incidence of surgical site infections. Databases searched include the Cumulative Index to Nursing and Allied Health Literature, MEDLINE, Embase, and Cochrane Central. Our review was limited to eight peer-reviewed, randomized controlled trials and two nonrandomized controlled trials published in English from 1990 to 2015. Comparison models included traditional hand scrubbing with chlorhexidine gluconate or povidone-iodine against alcohol-based hand rubbing, scrubbing with a brush versus without a brush, and detergent-based antiseptics alone versus antiseptics incorporating alcohol solutions. Evidence showed that hand rubbing techniques are as effective as traditional scrubbing and seem to be better tolerated. Hand rubbing appears to cause less skin damage than traditional scrub protocols, and scrub personnel tolerated brushless techniques better than scrubbing using a brush. PMID:27129749

    Wastewater reuse has become an important alternative to agricultural irrigation; on the other hand, it poses concern with regard to public health. Total coliform and Escherichia coli concentration, presence of helminth eggs and Salmonella, and physical-chemical parameters were evaluated in raw and treated wastewater. Chemical and biochemical oxygen demand removal efficiency was 74.6 and 77.9%, respectively. As for organic nitrogen, total phosphorus, and total suspended solids, total efficiency removal was 17.4, 12.5, and 32.9%, respectively. The average density of total coliforms and E. coli was 3.5 x 10(9) and 1.8 x 10(8) MPN/100 mL and 1.1 x 10(7) MPN/100 mL and 3.9 x 10(5) MPN/100 mL for raw and treated wastewater, respectively. Ascaris eggs were observed in 80.8% of the samples collected, and viable eggs in 42.3% of the samples. Salmonella was detected in 36.4% of the samples. The values observed in treated wastewater did not show the adequate bacteriological quality, as recommended by World Health Organization (Geneva, Switzerland). Therefore, additional measures should be taken to achieve an improved microbiological and parasitological quality. PMID:18419008

    This study developed and validated a model for predicting the probability that communities in Amhara Region, Ethiopia, have low sanitation coverage, based on environmental and sociodemographic conditions. Community sanitation coverage was measured between 2011 and 2014 through trachoma control program evaluation surveys. Information on environmental and sociodemographic conditions was obtained from available data sources and linked with community data using a geographic information system. Logistic regression was used to identify predictors of low community sanitation coverage (< 20% versus ≥ 20%). The selected model was geographically and temporally validated. Model-predicted probabilities of low community sanitation coverage were mapped. Among 1,502 communities, 344 (22.90%) had coverage below 20%. The selected model included measures for high topsoil gravel content, an indicator for low-lying land, population density, altitude, and rainfall and had reasonable predictive discrimination (area under the curve = 0.75, 95% confidence interval = 0.72, 0.78). Measures of soil stability were strongly associated with low community sanitation coverage, controlling for community wealth, and other factors. A model using available environmental and sociodemographic data predicted low community sanitation coverage for areas across Amhara Region with fair discrimination. This approach could assist sanitation programs and trachoma control programs, scaling up or in hyperendemic areas, to target vulnerable areas with additional activities or alternate technologies.

    Deep eutectic solvents (DESs) are emerging rapidly as a new type of green solvent instead of an ionic liquid (IL), and are typically formed by mixing choline chloride with hydrogen bond donors. Few studies have applied DESs to the extraction and determination of bioactive compounds. Therefore, in the present study, DESs were used to extract flavonoids (myricetin and amentoflavone), which are well known and widely used antioxidants, to extend their applications. A range of alcohol-based DESs with different alcohols to choline chloride (ChCl) mixing ratios were used for extraction using several extraction methods. Other factors, such as temperature, time, water addition and solid/liquid ratio, were examined systematically using a response surface methodology (RSM). A total of 0.031 and 0.518 mg g(-1) of myricetin and amentoflavone were extracted under the optimized conditions: 35 vol% of water in ChCl/1,4-butanediol (1/5) at 70.0 °C for 40.0 min and a solid/liquid ratio of 1/1 (g 10 mL(-1)). Good linearity was obtained from 0.1 × 10(-3) to 0.1 mg mL(-1) (r(2)>0.999). The excellent properties of DESs highlight their potential as promising green solvents for the extraction and determination of a range of bioactive compounds or drugs. PMID:23481471

    An artificial dexterous hand is provided for conformally engaging and manipulating objects. The hand includes an articulated digit which is connected to an engagement sub-assembly and has a first shape adaption mechanism associated with it. The digit has a digit base and first and second phalanges. The digit base is operatively interconnected to the first phalange by a base joint having a base pulley. The phalanges are operatively interconnected by a separate first phalange joint having a first phalange pulley. The engagement sub-assembly includes a tendon, which is received by the base pulley and by the first phalange pulley, and an actuation device for selectively tensioning the tendon. The first shape adaption mechanism is responsive to and receives the tendon. It is also situated between the base joint and the first phalange joint and is connected to the first phalange. Upon actuation by the actuation device, the phalanges are caused to pivot relative to the base joint and the second phalange is caused to pivot relative to the first phalange. At the same time, the first shape adaption mechanism controls the sequence of the aforementioned pivoting of the phalanges through application of braking force to the tendon.

The study demonstrates the feasibility of using such an approach to evaluate two levels of water supply and sanitation service quickly and at moderate cost. Sample sizes would need to be increased substantially to evaluate multiple levels of service or to investigate interactions between water supply and sanitation. The results indicate that children living in families who use good quality water supplies and latrines experience 20% less diarrhoea as reported to the health clinics during the warm, rainy season.

    Background The practice of sharing sanitation facilities does not meet the current World Health Organization/UNICEF definition for what is considered improved sanitation. Recommendations have been made to categorize shared sanitation as improved sanitation if security, user access, and other conditions can be assured, yet limited data exist on user preferences with respect to shared facilities. Objective This study analyzed user perceptions of shared sanitation facilities in rural households in East Java, Indonesia, and Bangladesh. Methods Cross-sectional studies of 2,087 households in East Java and 3,000 households in Bangladesh were conducted using questionnaires and observational methods. Relative risks were calculated to analyze associations between sanitation access and user perceptions of satisfaction, cleanliness, and safety. Results In East Java, 82.4% of households with private improved sanitation facilities reported feeling satisfied with their place of defecation compared to 68.3% of households with shared improved facilities [RR 1.19, 95% CI 1.09, 1.31]. In Bangladesh, 87.7% of households with private improved facilities reported feeling satisfied compared to 74.5% of households with shared improved facilities [RR 1.15, 95% CI 1.10, 1.20]. In East Java, 79.5% of households who reported a clean latrine also reported feeling satisfied with their place of defecation; only 38.9% of households who reported a dirty latrine also reported feeling satisfied [RR 1.74, 95% CI 1.45, 2.08]. Conclusion Simple distinctions between improved and unimproved sanitation facilities tend to misrepresent the variability observed among households sharing sanitation facilities. Our results suggest that private improved sanitation is consistently preferred over any other sanitation option. An increased number of users appeared to negatively affect toilet cleanliness, and lower levels of cleanliness were associated with lower levels of satisfaction. However, when sanitation

    Case study research often claims culture-variously defined-impacts infrastructure development. I test this claim using Hofstede's cultural dimensions and newly available data representing change in national coverage of sewer connections, sewerage treatment, and onsite sanitation between 1990 and 2010 for 21 developing nations. The results show that the cultural dimensions of uncertainty avoidance, masculinity-femininity, and individualism-collectivism have statistically significant relationships to sanitation technology choice. These data prove the global impact of culture on infrastructure choice, and reemphasize that local cultural preferences must be considered when constructing sanitation infrastructure. PMID:25961326

    There is a move throughout the developed world to introduce benchmarking techniques to the management of water and sanitation systems. The indicators that are being considered for benchmarking purposes tend to cover a broad band of activities that are part of the scope of management of large organisations. Most of the lists that have been prepared do not really cater for the implementation and operation of small rural schemes. The greatest need is the implementation of sustainable schemes for this category of consumer. The implementation of a rural water and sanitation scheme involves the negotiation in the initial stages with the local community representatives of what the community wants and how it will be provided and operated. This may have to be preceded by a period of empowerment so that the negotiations can be conducted by informed people. At the conclusion of the negotiations a business plan can be prepared that should be implemented in association with the community. The project is at this stage mainly in the control of a professional engineer, responsible for the technical interpretation of the business plan and the management of the construction phase. Finally, after commissioning, a water service provider will be responsible for the operation, management and maintenance of the scheme on a sustainable basis. The key actions and activities are identified and performance criteria defined. As communication at the beginning of the project is a critical component, the success of this is confirmed by examination and discussion as to how much has in fact been communicated and understood correctly. Other performance indicators for the operational phase are derived from the conventional ones used in the developed world. Finally, it is important that the participants, do not see the measurement of performance as a threatening situation, but rather a stepping stone to improvement of not only performance, but also of subsequent reward.

    2014-01-01

    Background Hand hygiene is considered one of the most important infection control measures in human healthcare settings, but there is little information available regarding hand hygiene frequency and technique used in veterinary clinics. The objectives of this study were to describe hand hygiene practices associated with routine appointments in companion animal clinics in Ontario, and the effectiveness of a poster campaign to improve hand hygiene compliance. Results Observation of hand hygiene practices was performed in 51 clinics for approximately 3 weeks each using 2 small wireless surveillance cameras: one in an exam room, and one in the most likely location for hand hygiene to be performed outside the exam room following an appointment. Data from 38 clinics were included in the final analysis, including 449 individuals, 1139 appointments before and after the poster intervention, and 10894 hand hygiene opportunities. Overall hand hygiene compliance was 14% (1473/10894), while before and after patient contact compliance was 3% (123/4377) and 26% (1145/4377), respectively. Soap and water was used for 87% (1182/1353) of observed hand hygiene attempts with a mean contact time of 4 s (median 2 s, range 1-49 s), while alcohol-based hand rub (ABHR) was used for 7% (98/1353) of attempts with a mean contact time of 8 s (median 7 s, range 1-30 s). The presence of the posters had no significant effect on compliance, although some staff reported that they felt the posters did increase their personal awareness of the need to perform hand hygiene, and the posters had some effect on product contact times. Conclusions Overall hand hygiene compliance in veterinary clinics in this study was low, and contact time with hand hygiene products was frequently below current recommendations. Use of ABHR was low despite its advantages over hand washing and availability in the majority of clinics. The poster campaign had a limited effect on its own, but could still be used as a

    A relatively simple, compact artificial hand, is described which includes hooks pivotally mounted on first frame to move together and apart. The first frame is rotatably mounted on a second frame to enable "turning at the wrist" movement without limitation. The second frame is pivotally mounted on a third frame to permit 'flexing at the wrist' movement. A hook-driving motor is fixed to the second frame but has a shaft that drives a speed reducer on the first frame which, in turn, drives the hooks. A second motor mounted on the second frame, turns a gear on the first frame to rotate the first frame and the hooks thereon. A third motor mounted on the third frame, turns a gear on a second frame to pivot it.

    In a household appliance plant, several rinse-free lubricating fluids have been used instead of neat mineral oils since 1994: mixtures of isoparaffinic hydrocarbons with 9 to 14 carbons per molecule. As such they denature keratin, irritate and defat the skin, and remove water from it. Work gloves have been worn over plastic gloves and separate, reusable, cotton inner gloves have been added to absorb sweat since skin problems were first recognized in 1994. All 74 males (mean +/- SD, 38.8 +/- 8.0 years) who work with the fluids were interviewed and given cutaneous examinations when indicated. While 4 cases of severe dermatitis and 31 cases of mild dermatitis were identified, 28 individuals gave a history of similar problems since the use of lubricating fluids. Their symptoms were typical of primary skin irritation. The hands were the commonly affected region (63 of 63 cases: 100%), followed by the thighs (15.9%) and trunk (11.1%). The work-related skin symptoms identified were less common in workers who immediately removed the liquid with soap and water, when it is spilled on the hands, than in those who did not, but the difference was not statistically significant (7/23 (30.4%) vs. 28/51 (54.9%), p=0.051 by chi-square test). Since skin contact with metalworking fluids (MWF) is often unavoidable, good personal hygiene is important in minimizing potential adverse health effects. Health education thus remains the most important preventive measure against irritant contact dermatitis among workers handling MWFs. PMID:12141380

    We performed a prospective multicenter study to assess the dryness and irritation of the hands in health care facilities, and to evaluate whether that disinfection with an alcohol-based hand rub (ABHR) is better tolerated than classic handwashing with mild soap and water. Our study was conducted in 9 sites in the summer and winter. A team of investigators evaluated dryness and irritation. This study takes into account most of the individual and environmental risk factors (age, sex, use of a protective agent, constitutional factors, personal factors, external factors, institution, function, and number of consecutive working days). The results from the 1932 assessments collected show that traditional handwashing is a risk factor for dryness and irritation, whereas the use of ABHR causes no skin deterioration and might have a protective effect, particularly in intensive use. These results provide a strong argument to counter the rear-guard resistance to the use of ABHRs. PMID:20650547

    The aim of this study was to objectively assess the hand hygiene performance of medical students. Hand rubbing technique was evaluated by employing innovative UV-light-based imaging technology, identifying patterns and trends in missed areas after applying WHO's six-step protocol. This specially designed hand hygiene education and assessment program targeted 1,344 medical students at two distant sites in Central Europe. Students were introduced to a short video, presenting the basics of hand hygiene, and then received further demonstration from professional trainers, focusing on the correct execution of WHO's six-step technique. To verify the acquired skill, participants rubbed their hands with UV-marked alcohol-based solution. Digital images of the hands were recorded under UV light, followed by computer evaluation and assessment. Immediate objective visual feedback was given to the participants showing missed areas on their hands. The statistical analysis of missed spots was based on retrospective expert-driven manual evaluation. Significant difference in rubbing quality was found between female and male participants [35.3% (CI 95%: 33-38%) versus 29.0% (CI 95%: 27-31%), p < 0.001], dominant and non-dominant hands [43.4% (CI 95%: 39-48%) versus 34.9% (CI 95%: 32-38%), p = 0.002], and various zones of the hands' dorsal side. Based on the participants' feedback and the evaluation of the infection control specialists, it can be stated that the identification of typically missed patterns and the instant visual feedback have a vital role in improving the hand hygiene technique of prospective medical staff.

    Rapid population growth and urbanization are exerting excessive pressure on soil and water resources. To address these problems this paper proposes a cheap and sustainable alternative sanitation system, which accelerates nutrient recycling ("closing the loop"): ecological sanitation (ecosan) is a potential alternative to conventional sanitation systems that replenishes the organic matter and nutrients of the soil that are taken off as the crop harvest. A comparison is made of the environmental and the operation and maintenance costs between a modern wastewater treatment plant and on-site sanitation. An elevated double box urine diverting toilet ("ecotoilet") is proposed and its advantages and disadvantages over a system with a centrally controlled modern WWTP are discussed. Bagmati Area Sewerage Project in Kathmandu is taken as an example of modern WWTP and ecosan being practiced in a village in Nepal is taken as an example of ecotoilet for the comparison.

    While sanitation interventions have focused primarily on child health, women's unique health risks from inadequate sanitation are gaining recognition as a priority issue. This study examines the range of sanitation-related psychosocial stressors during routine sanitation practices in Odisha, India. Between August 2013 and March 2014, we conducted in-depth interviews with 56 women in four life stages: adolescent, newly married, pregnant and established adult women in three settings: urban slums, rural villages and indigenous villages. Using a grounded theory approach, the study team transcribed, translated, coded and discussed interviews using detailed analytic memos to identify and characterize stressors at each life stage and study site. We found that sanitation practices encompassed more than defecation and urination and included carrying water, washing, bathing, menstrual management, and changing clothes. During the course of these activities, women encountered three broad types of stressors-environmental, social, and sexual-the intensity of which were modified by the woman's life stage, living environment, and access to sanitation facilities. Environmental barriers, social factors and fears of sexual violence all contributed to sanitation-related psychosocial stress. Though women responded with small changes to sanitation practices, they were unable to significantly modify their circumstances, notably by achieving adequate privacy for sanitation-related behaviors. A better understanding of the range of causes of stress and adaptive behaviors is needed to inform context-specific, gender-sensitive sanitation interventions. PMID:26164119

    This work fits into the context of the interpretation of automatic gestures based on computer vision. The aim of our work is to transform a conventional screen in a surface that allows the user to use his hands as pointing devices. These can be summarized in three main steps. Hand detection in a video, monitoring detected hands and conversion paths made by the hands to computer commands. To realize this application, it is necessary to detect the hand to follow. A classification phase is essential, at the control part. For this reason, we resorted to the use of a neuro-fuzzy classifier for classification and a pattern matching method for detection.

    Background Access to sanitation facilities is imperative in reducing the risk of multiple adverse health outcomes. A distinct disparity in sanitation exists among different wealth levels in many low-income countries, which may hinder the progress across each of the Millennium Development Goals. Methods The surveyed households in 397 clusters from 2008–2009 Kenya Demographic and Health Surveys were divided into five wealth quintiles based on their national asset scores. A series of spatial analysis methods including excess risk, local spatial autocorrelation, and spatial interpolation were applied to observe disparities in coverage of improved sanitation among different wealth categories. The total number of the population with improved sanitation was estimated by interpolating, time-adjusting, and multiplying the surveyed coverage rates by high-resolution population grids. A comparison was then made with the annual estimates from United Nations Population Division and World Health Organization /United Nations Children's Fund Joint Monitoring Program for Water Supply and Sanitation. Results The Empirical Bayesian Kriging interpolation produced minimal root mean squared error for all clusters and five quintiles while predicting the raw and spatial coverage rates of improved sanitation. The coverage in southern regions was generally higher than in the north and east, and the coverage in the south decreased from Nairobi in all directions, while Nyanza and North Eastern Province had relatively poor coverage. The general clustering trend of high and low sanitation improvement among surveyed clusters was confirmed after spatial smoothing. Conclusions There exists an apparent disparity in sanitation among different wealth categories across Kenya and spatially smoothed coverage rates resulted in a closer estimation of the available statistics than raw coverage rates. Future intervention activities need to be tailored for both different wealth categories and nationally

    A prosthetic device for below-the-elbow amputees, having a C-shaped clamping mechanism for grasping cylindrical objects, is described. The clamping mechanism is pivotally mounted to a cuff that fits on the amputee's lower arm. The present invention is utilized by placing an arm that has been amputated below the elbow into the cuff. The clamping mechanism then serves as a hand whenever it becomes necessary for the amputee to grasp a cylindrical object such as a handle, a bar, a rod, etc. To grasp the cylindrical object, the object is jammed against the opening in the C-shaped spring, causing the spring to open, the object to pass to the center of the spring, and the spring to snap shut behind the object. Various sizes of clamping mechanisms can be provided and easily interchanged to accommodate a variety of diameters. With the extension that pivots and rotates, the clamping mechanism can be used in a variety of orientations. Thus, this invention provides the amputee with a clamping mechanism that can be used to perform a number of tasks.

    Diarrheal disease remains a leading cause of morbidity in areas with limited access to safe water and sanitation. As water and sanitation interventions continue to be implemented, it will be important to understand the ecological context in which they can prevent diarrhea. We conducted six serial case control studies in Ecuador to estimate the risk of diarrhea from unimproved water and sanitation and the potential for effect modification by rainfall. Unimproved water source and unimproved sanitation increased the adjusted odds of diarrhea (odds ratio [OR] = 3.6, 95% confidence interval [95% CI] = 1.7-7.8 and OR = 1.7, 95% CI = 1.2-2.5, respectively). The OR associated with an unimproved water source was highest after maximum rainfall (OR = 6.8, 95% CI = 1.9-24.5), whereas the OR associated with unimproved sanitation was highest after minimal rainfall (OR = 2.9, 95% CI = 1.3-6.6). Our finding that use of safe water sources and improved sanitation facilities are most protective under opposing rainfall conditions highlights the need for integrated interventions to reduce the burden of diarrheal disease.

    Despite the prominence of communal practices as a last resort for any decent way of sanitation in slum areas, its application and use is flagrantly ignored. This paper provides insight in the appropriateness of communal sanitation facilities for slum conditions. Recent scholarly investigations in developing countries provide theoretical and empirical evidence of a divergence between the expectations from the users of sanitation facilities, and the expectations from other stakeholders. This paper presents the results from a case study in the Kibera slum attached to Nairobi, which is one of the largest African slums. A series of interviews with government agencies, Non-Governmental Organisations and Community Building Organisations was carried out. In addition, a survey was conducted of 76 users of different sanitation facilities. The research culminates in a series of concerns on financial, technological, situational and participatory dimensions. The main conclusion is a firm confirmation that communal sanitation are indeed the only viable alternative for slums, and therefore, the results of the research advocate a serious recognition of the use and appropriateness of communal sanitation for slum dwellers.

  19. Economic aspects of rural sanitation in the United States of America.

    Although health conditions in the rural areas of the USA are comparatively good, they are inferior to those in the urban areas. An important reason for this inferiority is the fact that rural sanitation is less a social responsibility than an individual responsibility, which many rural families cannot finance. The rural culture imposes many handicaps on the rural family's health and wealth. Such handicaps may be moderated by sanitation and related social and economic measures, if the measures selected are appropriate to the local needs and resources, which may vary greatly. Although sanitation needs are common to all rural areas, the refinement and complexity of sanitation facilities and services cannot be uniform. Allowing for variable circumstances, however, the basic elements of rural sanitation in the USA can be realized within a generation. The probable net gains in farm productivity would seem to warrant support for a rural sanitation programme on economic grounds alone, if an economic market may be assumed for the increase in agricultural production.

    A total of 144 studies were analysed to examine the impact of improved water supply and sanitation facilities on ascariasis, diarrhoea, dracunculiasis, hookworm infection, schistosomiasis, and trachoma. These diseases were selected because they are widespread and illustrate the variety of mechanisms through which improved water and sanitation can protect people. Disease-specific median reduction levels were calculated for all studies, and separately for the more methodologically rigorous ones. For the latter studies, the median reduction in morbidity for diarrhoea, trachoma, and ascariasis induced by water supplies and/or sanitation was 26%, 27%, and 29%, respectively; the median reduction for schistosomiasis and dracunculiasis was higher, at 77% and 78%, respectively. All studies of hookworm infection were flawed apart from one, which reported a 4% reduction in incidence. For hookworm infection, ascariasis, and schistosomiasis, the reduction in disease severity, as measured in egg counts, was greater than that in incidence or prevalence. Child mortality fell by 55%, which suggests that water and sanitation have a substantial impact on child survival. Water for personal and domestic hygiene was important in reducing the rates of ascariasis, diarrhoea, schistosomiasis, and trachoma. Sanitation facilities decreased diarrhoea morbidity and mortality and the severity of hookworm infection. Better water quality reduced the incidence of dracunculiasis, but its role in diarrhoeal disease control was less important than that of sanitation and hygiene. PMID:1835675
