Pregnant women that presented with vaginal candidiasis constituted 40%(n=360) of the total 840 cases.Other risk groups included the immuno-suppression with 24%(n=202),group on hormonal therapy with 15%(n=126) and broad spectrum antibiotics users with 16%(n=134).Conclusions: The results show that Candida is the most common cause of vaginitis and vulvo-vaginal candidiasis followed by C.albicans in the young adults aged 21 to 30 years,pregnant mothers, immuno-suppression,contraceptive and broad spectrum antibiotic users.Proper management of vaginal candidiasis and vulvo-vaginal candidiasis is recommended especially among the risk groups in order to avoid complications and reduce HIV transmission.

Swab culture monitoring of automated endoscope reprocessors after high-level disinfection

AIM:To conduct a bacterial culture study for monitoring decontamination of automated endoscope reprocessors(AERs) after high-level disinfection(HLD).METHODS:From February 2006 to January 2011,authors conducted randomized consecutive sampling each month for 7 AERs.Authors collected a total of 420 swab cultures,including 300 cultures from 5 gastroscope AERs,and 120 cultures from 2 colonoscope AERs.Swab cultures were obtained from the residual water from the AERs after a full reprocessing cycle.Samples were cultured to test for aerobic bacteria,anaerobic bacteria,and mycobacterium tuberculosis.RESULTS:The positive culture rate of the AERs was 2.0%(6/300) for gastroscope AERs and 0.8%(1/120) for colonoscope AERs.All the positive cultures,including 6 from gastroscope and 1 from colonoscope AERs,showed monofloral colonization.Of the gastroscopeAER samples,50%(3/6) were colonized by aerobic bacterial and 50%(3/6) by fungal contaminations.CONCLUSION:A full reprocessing cycle of an AER with HLD is adequate for disinfection of the machine.Swab culture is a useful method for monitoring AER decontamination after each reprocessing cycle.Fungal contamination of AERs after reprocessing should also be kept in mind.

Endocervical Swab Microbial Isolates among Women with Third Degree Uterovaginal Prolapse

Background: Uterovaginal prolapse is the descent of the uterus through the vaginal canal. This may be a predisposing factor to infections in the urogenital system. This study aimed to assess the endocervical swab microscopy, culture and sensitivity in patients with third degree uterovaginal prolapse at the National Obstetric Fistula Centre, Abakaliki, South-East Nigeria. Methodology: This is a cross-sectional prospective study to assess the endocervical swab microbial findings in patients with third degree uterovaginal prolapse using simple random sampling technique. Data on sociodemographic variables, risk factors for pelvic organ prolapse, and endocervical swab findings among women with third degree uterovaginal prolapse were collated and analysed using statistical methods. Results: The mean age and parity were 50.5 years ± 9.1 and 6.7 ± 2.0 respectively. Thirty-six (85.7%) of the clients were grandmultipara and 37 (88.1%) were farmers. Pus cells were present in all samples while 27 (64.3%) had microbial isolates. Streptococcus pyogenes was isolated in 7 (16.7%), Streptococcus faecalis in 5 (11.9%), Escherichia coli in 5 (11.9), Staphylococcus aureus in 4 (9.5%), Klebsiella pneumoniae in 2 (4.8%) and Yeast cells in 4 (9.5%) of the endocervical swabs. All isolates were sensitive to gentamicin. Bacterial isolates were resistant to amoxicillin/clavulanic acid.

Association of the microbial culture of follicular fluid,vaginal swab and catheter tip with β-hCG IVF positive and negative

Objective:To find out the association of microbial contamination withβ-human chorionic gonadotropin(β-hCG)in-vitro fertilization(IVF)positive and negative.Methods:A total of 73 fresh IVF cycle women were included in the retrospective study.Vaginal swab culture samples were collected prior to ovum pick-up and embryo transfer.The follicular fluids were collected during ovum pick-up and catheter tip culture samples were collected after successful embryo transfer.After 14 days of the embryo transfer,women were classified intoβ-hCG IVF positive and negative.The comparative statistical analyses of aerobic microbial culture reports were done betweenβ-hCG IVF positive and negative women.Results:Out of 73 women,42(57.5%)were found to beβ-hCG IVF positive and 31(43.5%)were negative.In the aerobic culture of ovum pick-up vaginal swab,follicular fluid,embryo transplantation vaginal swab and catheter tip,Enterococcus faecalis was found to be higher compared to other bacteria(Streptococcus spp.,Candida,Escherichia coli and Klebsiella).Regarding the comparison between IVF positive and negative,the overall microbial infection rate of vaginal swab culture during ovum pick-up and embryo transplantation was found to be higher in IVF negative women than in IVF positive women(38.71%vs.28.57%);however,it was not statistically significant(P>0.05).The follicular fluid and catheter tip culture microbial infection rate was found to slightly higher in IVF positive women than in IVF negative women(54.76%vs.41.94%and 19.05%vs.9.68%,respectively),but there were not significant differences(P>0.05).Conclusions:The aerobic microbial culture reports of follicular fluid,vaginal swab culture,and catheter tip culture are not statistically significantly withβ-hCG IVF positive.

COVID-19 Pandemic Waves in Italy: An Epidemiological Overview about Infections, Swabs and Death Rates

Introduction: On March 11, 2020, the World Health Organization (WHO) declared that the entire World was overrun by a pandemic. Science has managed, in a short time, to characterize a new disease, sequence a new viral genome, develop diagnostics, produce treatment protocols and establish the efficacy of drugs and vaccines in randomized controlled trials. In this paper we have dealt with different topics regarding the pandemic linked to COVID-19. Objectives: Aim of this paper is to compare the number of deaths attributable to COVID-19, that occurred in the different Italian macro-areas, in the different pandemic waves;we studied the trend of the curves relating to the proportion of deaths to the number of infected in the Italian macro-areas for the pandemic waves and analysed the mortality data, focusing on the Italian context and comparing it with other foreign countries. We examined the data regarding swabs, hospitalizations, home isolation, admissions to intensive care and deaths registered in pandemic period. Results: Geographically, Italy was differently affected by the pandemic. Northern Italy was the most affected area. In comparison with some foreign countries, Italy is one of the nations that paid the most in terms of deaths, due to: delays in understanding the seriousness of the emergency;the slow management in the tracking systems of contagions;the high number of hospitalizations;a corporate organizational system poorly planned. Conclusion: The years 2020 and 2021 have been dramatic and unprecedented. The year 2021 was the year of redemption, where, despite social, economic and health difficulties, thanks to mass vaccination, we were able to give a real strong response to the pandemic. Trust in science has led to a drastic decrease in mortality throughout the world.

Visual Positioning of Nasal Swab Robot Based on Hierarchical Decision

This study focuses on a robot vision localization method for coping with the operational task ofautomatic nasal swab sampling. The application is important in the detection and epidemic prevention of CoronaVirus Disease 2019 (COVID-19) to alleviate the large-scale negative impact of individuals suffering from pneumoniaowing to COVID-19. In this method, the idea of a hierarchical decision network is used to consider the stronginfectious characteristics of the COVID-19, which is followed by processing the robot behavior constraint condition.The visual navigation and positioning method using a single-arm robot for sampling is also planned, whichconsiders the operation characteristics of medical staff. In the decision network, the risk factor for potentialcontact infection caused by swab sampling operations is established to avoid the spread among personnel. A robotvisual servo control with artificial intelligence characteristics is developed to achieve a stable and safe nasal swabsampling operation. Experiments demonstrate that the proposed method can achieve good vision positioning forthe robots and provide technical support for managing new major public health situations.

Seed amplification assay of nasal swab extracts for accurate and non-invasive molecular diagnosis of neurodegenerative diseases

Nasal swabs are non-invasive testing methods for detecting diseases by collecting samples from the nasal cavity or nasopharynx.Dysosmia is regarded as an early sign of coronavirus disease 2019(COVID-19),and nasal swabs are the gold standard for the detection.By nasal swabs,severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)nucleic acids can be cyclically amplified and detected using real-time reverse transcriptase-polymerase chain reaction after sampling.Similarly,olfactory dysfunction precedes the onset of typical clinical manifestations by several years in prion diseases and other neurodegenerative diseases,such as Alzheimer’s disease,Parkinson’s disease,dementia with Lewy bodies,and multiple system atrophy.In neurodegenerative diseases,nasal swab tests are currently being explored using seed amplification assay(SAA)of pathogenic misfolded proteins,such as prion,α-synuclein,and tau.These misfolded proteins can serve as templates for the conformational change of other copies from the native form into the same misfolded form in a prion-like manner.SAA for misfolded prion-like proteins from nasal swab extracts has been developed,conceptually analogous to PCR,showing high sensitivity and specificity for molecular diagnosis of degenerative diseases even in the prodromal stage.Cyclic amplification assay of nasal swab extracts is an attractive and feasible method for accurate and non-invasive detection of trace amount of pathogenic substances for screening and diagnosis of neurodegenerative disease.
