[Selected risk factors for occupational exposures to blood-borne pathogens in cosmetics salons]. / Wybrane czynniki ryzyka ekspozycji zawodowych na patogeny krwiopochodne w salonach kosmetologicznych.

BACKGROUND: Services offered in the esthetic/beauty industry poses the risk of blood-borne infections (BBIs) due to carrying out invasive procedures. The study objective: was to assess the number of sharps injuries, occupational risk factors, and preventive methods used among cosmetologists. MATERIAL AND METHODS: The anonymous survey was conducted (February-April 2017) in randomly selected beauty/esthetic medicine clinics in Szczecin, Poland; 96 cosmetologists were invited. RESULTS: Eighty cosmetologists (83.3%), responded. The mean age of the group was 25 years (range: 20-60 years). The majority of the respondents (95%) used sharps while at work, 41.3% had suffered at least one sharps injury during their occupational career. Clippers were the most common injury-causing instrument (39.4%), and manicure/pedicure was the most common injury-causing procedure (51.5%); 84.8% of injuries were not reported. The number of injuries was associated with age (34.9% in the group of 20-29 years old respondents vs. 64.7% in respondents ≥ 30 years old, p = 0.05), work experience (32.6% in the respondents working for 1-3 years vs. 68.8%, in those working ≥ 7 years, p = 0.03), and working hours/week (28.9% in those working ≤ 40 h vs. 57.1% of those working > 40 h, p = 0.02). Needle recapping was reported by 47.5% of respondents, 13.8% did not dispose used needles into a container, 17.5% did not routinely use gloves. CONCLUSIONS: Cosmetologists are at risk of sharps injuries. Inconsistent use of preventive methods and failure to report incidents may result in contracting BBIs. There is a need to implement education and intervention measures to prevent occupational injuries, particularly with regard to cosmetologists aged over 30 years, with a longer professional experience, working over 40 h/week.

A cross-sectional sero-survey on preoperative HBV vaccination policy in Poland.

BACKGROUND: A two-dose preoperative vaccination schedule against HBV has been the widely accepted policy in Poland. However, its effectiveness has not yet been assessed. OBJECTIVE: To evaluate a two-dose preoperative HBV vaccination policy by an assessment of the proportion of patients who don't present a protective level of anti-HBs (<10.0 mIU/ml). METHODS: Consecutive patients from surgical/gynecologic wards of 12 randomly selected hospitals in West Pomerania, Poland, hospitalized between 2010 and 2013, vaccinated against HBV with a two-dose regimen, were asked to complete an anonymous questionnaire. Serum samples were assayed for anti-HBs with the use of third-generation testing methods. To compare sensitivity versus specificity across a range of values for the ability to predict a dichotomous outcome (a protection against HBV infection) a Receiver operating characteristic (ROC) curve was determined. RESULTS: There were 193 patients, 58.5% women, median age 52 years. Almost a half (46.0%) of the patients were operated on within 0-60 days of taking the second vaccine dose, 16.2% - 61-180 days after, 37.8% >180 days after. Anti-HBs titer was below a protective level in 49.2% of participants (0.0 mIU/ml in 17.8%, 0.1-9.9 mIU/ml in 31.4%); none of them were aware of this fact. Age ≤ 52 years (OR = 1.89) and having surgery more than 37.5 days after HBV vaccination (OR = 2.70) were associated with greater odds of being protected against HBV infection through vaccination. For the time frame between the second dose implementation and surgery 23 days, a sensitivity of 84% and specificity of 22% for obtaining protection against HBV infection was found, for the time frame >37.5 days - sensitivity remained high (80%), while specificity increased (41%); there was an apparent peek on the ROC curve between 38 and 60 day. In the group vaccinated 0-37.5 days before surgery, less patients had the protective level of anti-HBs titer than in vaccinated 38-60 days before surgery (32.3% vs 60.0%; p = 0.03). CONCLUSIONS: The success rate in achieving adequate immune protection with two dose HBV vaccination schedule in preoperatively vaccinated patients is relatively low, especially among those vaccinated less than five weeks prior to surgery. In more than a third of cases the standard three-dose regimen could have been implemented, as participants had time to complete a third dose. Current recommendations regarding a preoperative policy with a 2-dose vaccination schedule in Poland should be revised; the best time to perform surgery after the implementation of the second dose of vaccine in the context of patient protection against HBV infection would be between 38 and 60 days.

[HBV, HCV, and HIV infection prevalence among prison staff in the light of occupational risk factors]. / Wystepowanie zakazen HBV, HCV i HIV wsród personelu wieziennego w swietle zawodowych czynników ryzyka.

BACKGROUND: Objectives of the study: to assess the occupational risk for blood-borne infections (BBIs) among prison staff (number/ circumstances of blood exposures and preventive methods used), and to estimate the prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV). MATERIAL AND METHODS: The survey, which included serological testing with the use of 3-generation enzyme-linked immunosorbent assays (ELISA) was completed on active staff at a correctional facility in Goleniów, Poland, between June-July 2015. RESULTS: Response rate was 38%, 87 participants (aged 22-64 years, median: 34 years) agreed to participate. There were 88.5% males, correctional officers comprised 87.4% of the participants. Having had ≥ 1 blood exposure during professional career was reported by 28.7% respondents, 8% - sustained it in the preceding year. For correctional officers the last blood exposure was caused by a hollow-bore needle/razor blade during cell or manual searches. This was not reported by 83.3%. Participation rate in an infection control training was 85.1%. Hepatitis B virus vaccination uptake was 83.9%. Compliance with glove use was 75.9%, with protective eyewear - 28.7%. Regular use of both was reported by 9.2% of participants. The lack of their availability was the most common reason (79.7%) for non-compliance. Anti-HBc (hepatitis B core antigen) total/anti-HCV/anti-HIV prevalence was 2.3%, 1.1%, and 0%, respectively. CONCLUSIONS: Prison staff are at risk for occupational exposures to blood. Reporting of such incidents is poor, as well as compliance with personal protective equipment use, which place them at risk for acquiring BBIs. Anti-HCV prevalence is similar to that observed in the general population, anti-HBc total prevalence is lower, possibly due to high vaccination uptake, however, poor response rate limits precise prevalence estimates.

Prevalence of HBV Infection and Knowledge of Hepatitis B Among Patients Attending Primary Care Clinics in Poland.

It is well known that community awareness of hepatitis B (HB) can lead to vaccination and testing. The study objectives were to assess the prevalence of HBV infection and knowledge of HB among adult patients attending randomly selected primary care clinics. A cross-sectional sero-survey was conducted in March 2013 in the Zgorzelec region, Poland, with the use of an investigator-developed questionnaire containing 22 questions regarding HB knowledge. Serum samples were assayed for anti-HBc total and anti-HBs with enzyme immunoassay. The prevalence of anti-HBc total among 410 participants (median age 56 years) was 10.3 % (95 % CI 7.6-13.8 %), nobody was aware of an infection. The main sources of HB knowledge were the media and medical staff. The mean knowledge score was 14.8 ± 4.9; 76.7 % of the respondents had scores >50 %. Particular gaps were detected relating to knowledge of unprotected sexual intercourse and MTCT; 45.6 % patients were not aware of the potential asymptomatic course of HBV infection, 41.2 % about chronic HB treatment. A patient's low educational level was negatively associated with a high knowledge level; the willingness for further education on HB and HBV vaccination in the past were independently associated with good knowledge. In conclusion, the HBV infection remains a public health threat in Poland, since the prevalence of infection markers in asymptomatic adult patients was high. Knowledge gaps call for awareness campaigns which may increase testing and diagnosis, audiences representing lower education level should be targeted first. Knowledge on HB might serve as an effective tool in decision making regarding vaccination.

A cross-sectional serosurvey on hepatitis B vaccination uptake among adult patients from GP practices in a region of South-West Poland.

BACKGROUND: Hepatitis B is a significant health burden in Poland with nosocomial transmission being the main source of infection. Therefore, HBV vaccination is widely recommended for those not covered by the national immunisation program. OBJECTIVE: To assess the coverage and influencing determinants of HBV vaccination among adult patients attending GP clinics as well as to establish serological status in terms of HBV infection. METHODS: Patients who were seen consecutively in March 2013 at four randomly selected GP practices located in Zgorzelec county, in south-western part of Poland, were invited to participate and complete questionnaires on socio-demographic data and other factors related to vaccination. A pilot study was done in one urban GP practice in the city of Gryfino (Gryfino county), the results have been included in the study. Patients' immunisation status was assessed basing on vaccination cards and anti-HBs titer with the use of third-generation testing methods. In addition, serum samples were assayed for anti-HBc total. RESULTS: Response rate: 99.3 %. Of 410 participants (66.1 % females, median age 56 years), 55.4 % (95%CI:50.5-60.1 %) were previously vaccinated; in those 11.5 % took 2 doses, 66.1 % - 3 doses,18.1 % - 4 doses. Elective surgery was the main reason (57.7 %) for HBV immunization, 4.8 % - were vaccinated due to recommendations by GPs. The multivariable logistic regression model revealed that living in a city (OR 2.11), and having a surgery in the past (OR 2.73) were each associated with greater odds of being vaccinated. Anti-HBc total prevalence among those unvaccinated was 13.6 % (95%CI:9.3 %-19,5 %), and 7.2 % (95%CI:4.4-11.8 %) among those vaccinated. CONCLUSIONS: Low HBV immunization coverage among adult patients from GP clinics and the presence of serological markers of HBV infection among both - those unvaccinated and vaccinated call for comprehensive preventative measures against infection, including greater involvement of family doctors. Although interventions should cover the whole population, inhabitants living in the rural areas should be a group of special interest. Preoperative immunization for HBV seems to be an efficient public health tool to increase the vaccination uptake.

Concerns of occupational HIV infection among surgical Staff in the light of anti-HIV sero-status and the distribution of Δ32 allele of the CCR5 gene: a cross-sectional study.

UNLABELLED: Surgical staff might be considered at most risk of accidental viral infection due to their higher exposure to blood. AIM: To evaluate surgical staff concerns about occupational HIV infection, to determine contributing factors, to assess their sero-status regarding this pathogen, and the frequency of the Δ32 allele of the CCR5 gene. METHODS: With the use of a self-administered anonymous questionnaire a cross-sectional sero-survey was conducted from February 2009-January 2010 among doctors/nurses from the surgical/ gynaecological wards of 16 randomly selected hospitals in Western Pomerania, Poland. Fear level was measured by the use of the VAS scale (range 0-10). Serum samples were tested by ELISA. Genotyping was performed using a PCR-AFLP assay. RESULTS: Response rate 84.9%; 427 participants, 88.3% females; 84.8% nurses, 15.2% doctors (median age 42 years, range 22-61 years). More than two thirds of respondents (67.2%) overestimated HIV single exposure risk. The median level of occupational HIV fear was 6.67. The prevalence of anti-HIV was 0.0% (95%CI: 0-0.9%); 1.2% (95%CI: 0.5%-2.9%) of participants were homozygotes Δ32/Δ32. The stepwise regression model revealed that job category (nurse) was associated with HIV fear (p<0.001). CONCLUSIONS: The risk of contracting occupational HIV infection remains low; no anti-HIV positive individuals were found among surgical staff, one in one hundred were resistant to HIV infection. Staff members, especially nurses, were much concerned with acquiring an occupational HIV infection, possibly due to the lack of knowledge on single exposure risk. Educational actions and better access to specialists which would help surgical staff in managing anxiety at the workplace is urgently needed.

Endogenous or exogenous origin of vaginal candidiasis in Polish women?

Vaginal candidiasis is a common problem of clinical practice. Many studies have been conducted to explain its origin but only a few have included Polish women. The aim of the study was to determine the prevalence and similarity of oral, anal and vaginal Candida albicans strains isolated from Polish women with vaginal candidiasis. The study involved 20 from 37 recruited women. Swab samples were collected from their vagina, anus, and oral cavity at two-month intervals. All the women were treated with nystatin. Yeast were recovered and identified by the germ-tube test, API /Vitek system, typed by API ZYM and RAPD-PCR. Chi-square test was used to analyze the data. A total of 170 Candida albicans isolates were recovered from 180 samples collected 3 times from 3 sites of 20 women. Positive yeast vaginal cultures were found in all patients before administration of nystatin. Vaginal yeast recovery rate was decreased statistically significant in both follow-up visits (p= 0.001; p= 0.003). The same and different genotypes/biotypes were found concomitantly in a few body sites and/ or repeatedly at time interval from the same body site. The results support the concept of dynamic exchange of yeast within one woman and endogenous or exogenous origin of vaginal candidiasis.

[Attitudes of medical specialists toward HBV, HCV or HIV infected surgical staff and a sero-survey among staff members]. / Postawy personelu medycznego wobec osób zakazonych HBV, HCV lub HIV pracujacych w oddzialach zabiegowych oraz badania serologiczne pracowników.

BACKGROUND: Issues regarding the transmission of blood-borne viruses from infected medical personnel to patients are controversial to both parties. The aim of this study was to evaluate the attitudes towards disclosure of HBV/HCV/HIV-infected surgeons and the possibility of being forced to give up surgical procedures, as well as to assess the prevalence of anti-HBc total, HBsAg, anti-HCV and anti-HIV in surgical staff. MATERIAL AND METHODS: Using an anonymous questionnaire a cross-sectional sero-survey was conducted among surgeons and nurses of surgical wards in 16 randomly selected hospitals, Western Pomerania, Poland, from January to June 2009. Serum samples were tested for anti-HBc, HBsAg, anti-HCV and anti-HIV by ELISA tests. RESULTS: In the group of 427 participants (232 nurses, 65 doctors; a median age: 42 years), anti-HBc was found in 16.6%, HBsAg in 0.7%, anti-HCV in 1.4% and anti-HIV in 0%. The risk of a single exposure to HBV was correctly defined by 26.5% of participants, to HCV by 19.7%, to HIV by 18.7%. 16.2% participants stated that infected surgeons should disclose their HBV, HCV, or HIV serostatus, 39.8% and 42.6% that those HBV/HCV-infected and HIV-infected, respectively, should discontinue practicing surgery. Participants who correctly assessed the risk of contracting HIV/HBV/HCV after a single exposure were significantly (p = 0.0001; p = 0.03; p = 0.01, respectively) less likely to favor infected staff being forced to discontinue surgical procedures. CONCLUSIONS: A fraction of surgical staff showed detectable markers of HBV/HCV infection, they may be a source of infection for operated patients. Surgical staff's knowledge about occupational blood exposure risk was not satisfactory, which might have influenced the restrictive attitudes to force those infected with HBV/HCV/HIV to give up surgical procedures and a willingness to disclose their serological status.

[Assessment of occupational exposure to HBV, HCV and HIV in gynecologic and obstetric staff]. / Ocena zawodowego narazenia na zakazenie HBV, HCV i HIV u personelu oddzialow ginekologii i poloznictwa.

BACKGROUND: The aim of the study was to assess the occupational risk for hepatitis B, C and HIV in gynecologic and obstetric staff in the context of the number of sharps injuries, HBV immunization coverage, compliance with personal protective equipment (PPE) use and reporting of exposures. METHODS: A voluntary anonymous survey was carried out between January-June 2009 in 15 ran domly selected hospitals in West Pomerania, Poland. RESULTS: There were 110 participants (response rate 72%), 88.2% females, 11.8 males (aged 21-60 years; mean, 42 years); 80.9% nurses, 19.1% doctors. Among those 60.9% reported at least one sharps injury in the preceding year (Me = 1, range 1-12), 43.6% worked at least once a year with a recent abrasion or cut on their hands. The respondents reported the most recent injuries being caused by a hollow-bore needle (54.4%), a suture needle (26.5%), and an instrument (19.1%); 82.5% of such incidents went unreported. Compliance with PPE use was high for glove use (92.7%), much lower for protective eyewear (28.7%). Except one participant who reported acute symptomatic hepatitis B in the past (possibly due to previous surgery), all participants reported being immunized with HBV vaccine: 46.8%--took three doses, 48.6%-- a booster and 4.6% ended the regimen on two doses. CONCLUSIONS: Frequent sharps injuries, mostly unreported, work with unprotected recent abrasion or hands' cuts and lack of compliance with PPE use are important risk factors contributing to occupational HBV, HCV and HIV infections among gynecologic and obstetric staff. The risk of HBV infection has been significantly reduced by a complete immunization coverage observed among participants.

[Model-based estimates of the risk of HCV transmission from infected patients to gynaecologic and obstetric staff]. / Szacowanie ryzyka transmisji HCV od zakazonych pacjentek do personelu ginekologiczno-polozniczego z wykorzystaniem modelu matematycznego.

UNLABELLED: The risk of acquiring the hepatitis C virus (HCV) through percutaneous occupational exposure is dependent on three key variables: number of injuries, probability of a percutaneous injury transmitting HCV and prevalence of HCV infection in the patient population. OBJECTIVE: To estimate the prevalence of HCV infection in the gynaecological/obstetric patient population and thereafter estimate the risk of HCV transmission to personnel through occupational exposure. METHODS: The prevalence of anti-HCV was estimated through an anonymous serosurvey of gynaecological/ obstetric patients in 15 randomly selected hospitals in West Pomerania, Poland, from February 2008 to January 2009. Using own published data on the percutaneous injuries during gynaecological/obstetric surgeries and results obtained from serologic survey, the risk of annual occupational transmission of HCV to personnel was then derived with the use of a mathematical model. RESULTS: The prevalence of anti-HCV infection for 528 gynaecological/obstetric patients, aged 18-83 (median 45), was 0.76% (4/528; 95%CI: 0.29-1.93%). The estimated risk of HCV transmission from an HCV infected patient to an uninfected staff member may vary over a wide range (0.00007-0.1%), being dependent on the type of exposure; the average risk for a midwife was 0.0038% per annum (0.15% risk over a 40 year professional career). The estimated risk for a gynaecologist/obstetrician was 0.0076% and 0.30% respectively. CONCLUSIONS: The risk of an individual member of a gynaecological/obstetric staff acquiring HCV through occupational exposure is low, however a credible hazard still exists. One in 130 patients hospitalized at gynaecological/obstetric wards showed markers of HCV infection. Therefore, staff members should be encouraged to observe standard precautions regarding sharps injury prevention and present themselves for post-exposure management in case of need.

[Rationale for the implementation of pre-operative testing for HCV in the light of anti-HCV and HBsAG tests results in surgical patients from a teaching hospital]. / Przeslanki do wdroienia przedoperacyjnego badania pacjentów w kierunku zakazenia HCV w swietle wyników oznaczen anty-HCV i HBsAG w populacji pacjentów klinicznych oddzialow zabiegowych.

UNLABELLED: Many Polish hospitals compel patients admitted for elective surgery to be immunised for HBV; testing for HBsAg is recommended before. We surveyed immunisation coverage for HBV and prevalence of HBsAg and anti-HCV among surgical patients to assess existing pre-operative screening policies. METHODS: questionnaire data and sera were collected anonymously from 400 consecutive adults admitted to 4 surgical wards of a teaching hospital in Szczecin, Poland during October 2006/December 2007. Samples were assayed for HBsAg, and anti-HCV. RESULTS: Serologic evidence for either HBsAg or anti-HCV was 2.3% (9/400; 95% CI: 1.2-4.2%), all in elective cases; 1.5% (6/400; 95% CI: 0.7-3.2%) were positive for anti-HCV, 0.75% (3/400; 95% CI: 0.26-2.18%) for HBsAg. None of anti-HCV positive patients was aware of their infection, as well as 1 in 3 HBsAg carriers. Anti-HCV and HBsAg prevalence in 20131 blood donors which served as controls were 0.08% (95% CI: 0.02-0.15%) and 0.11% (95% CI: 0.04-0.2%) respectively. HBV immunisation coverage was 247/398 (62%), higher (p < 0.0001) in those undergoing elective rather than emergency surgery. CONCLUSIONS: anti-HCV prevalence was double that for HBsAg. These data give evidence for the expansion of the existing screening programme for blood borne infections among elective surgical patients, to also cover those infected with HCV. A third of patients were unimmunised, remaining a potential pool for HBsAg carriers.

Assessment of quality of life in patients with idiopathic scoliosis treated operatively.

BACKGROUND: A small percentage of patients with idiopathic scoliosis undergo surgery, which is only used in the case of the most extreme deformities of the spine and chest and progression of disease despite conservative treatment. The aim of this study was to assess the quality of life in patients with idiopathic scoliosis treated operatively and to examine the correlations between the quality of life and radiographic and socio-demographic indices. MATERIAL AND METHODS: wo independent groups of patients operated on at the Department of Pediatric Orthopedics of the Pomeranian Medical University in Szczecin were examined using a standardized SRS -22 HRQL instrument. Quality of life was assessed on three occasions in 35 patients from the first group. The second group included 52 patients at least two years post-surgery. RESULTS: The assessment of physical fitness revealed a decrease proportional to the length of time since surgery. Higher pain intensity was reported by patients whose surgery took place more than 2 years prior to the study. The analysis of mental health assessment results indicated a decrease proportional to the length of time since surgery. No statistically significant differences were found with respect to patients' self-assessment of their body image and treatment satisfaction. CONCLUSIONS: 1. Operative correction of scoliosis enhances patients' self-assessment of their body image and contributes to a high assessment score for treatment satisfaction. 2. No correlations were found between the overall quality of life and previous conservative treatment. 3. Deterioration of physical fitness, mental health impairment and increasing pain intensity were observed among patients residing in small towns and rural areas and those experiencing socioeconomic problems 4. The degree of scoliosis correction in the thoracic spine contributes to increasing life quality, especially in late assessment.

Infections with HBV, HCV and HIV in patients admitted to the neurosurgical department of a teaching hospital.

BACKGROUND AND PURPOSE: To estimate the prevalence of infection with HBV, HCV, HIV and immunization coverage against HBV among neurosurgical patients. MATERIAL AND METHODS: The study was designed as an anonymous serosurvey conducted at the neurosurgical department of Szczecin University Hospital. Between November and December 2007, blood samples from 100 consecutive patients were tested for anti-HIV, anti-HCV and HBsAg using a third-generation (ELISA) method. RESULTS: Response rate was 100%. Median age of participants was 51 years, 52% were males. The immunization coverage against HBV was 71% (95% CI: 61.5-79%), 24% (95% CI: 16.7-33.2%) were not immunized, and 5% of patients (95% CI: 2.2-11.2%) did not recall the procedure. There were no differences in immunization rates between emergencies and elective procedures. Four patients (4%; 95% CI: 1.6-9.8%) were positive either with HBV or HCV: 2 were HBsAg positive, 2 anti-HCV positive (2%; 95% CI: 0.6-7%). There were no HIV positive cases among patients. CONCLUSIONS: There is a potential risk to staff of contracting a blood-borne infection, as one in 25 patients was infected with HBV or HCV. Even if patients cover the cost of pre-operative immunization against HBV, with previous HBsAg testing, it would not guarantee the detection of all infected patients, as it refers only to some elective cases. Pre-operative screening for HBV, based on HBsAg testing in immunized patients, detected only 1/4 of patients infected with blood-borne hepatotropic viruses; asymptomatic patients infected with HCV remain a problem in the context of occupationally acquired infections. In the light of the low single exposure risk and lack of serological markers of infection among patients we conclude that employment at a neurosurgical department does not significantly increase the risk of contracting HIV infection.

Visual function and complications after cataract surgery with bilateral multifocal intraocular lens implantation.

PURPOSE: To evaluate the visual function and complications after cataract surgery with bilateral Array SA 40N multifocal intraocular lens (IOL) implantation. MATERIAL AND METHODS: This prospective study comprised 40 eyes of selected 20 patients undergoing cataract surgery with bilateral implantation of Array SA 40N (AMO). multifocal IOL. Three months after bilateral surgery distance and near visual acuity, contrast sensitivity, complications and adverse effects were evaluated. Patients' satisfaction was assessed using a subjective TyPE Questionnaire. RESULTS: Thirty-five eyes (35/40 - 87.5%) achieved the uncorrected distance visual acuity 20/40 and the uncorrected near visual acuity of J5 or better. Eighty-two and a half percent of the operated eyes achieved UCDVA 20/20 and J4 or better. Contrast sensitivity for distance and near measured binocularly were within normal limits, although for higher spatial frequency, contrast sensitivity values for near were slightly above the lower limit of normal range. Intraoperative and postoperative complications were few and only in one eye, further surgical intervention was necessary (IOL recentration). Three patients (3/20 - 15%) reported moderate glare and halo. Overall visual satisfaction measured with TyPE Questionnaire was very high (8.7/10). CONCLUSIONS: Bilateral multifocal IOL implantation was effective and safe in selected cataract patients, providing very good uncorrected distance and near visual acuity. Slightly reduced contrast sensitivity and increased perception of glare/halo were an acceptable compromise for near, as well as distance vision improvement.

A Cross-Sectional Study on Selected Correlates of High risk Sexual Behavior in Polish Migrants Resident in the United Kingdom.

Objective: To assess the correlates of the high risk sexual behaviors of Polish migrants in the United Kingdom (UK) after 2004, and to compare such behaviors before/after immigration. Methods: In 2013, a cross-sectional study was conducted through the use of a Computer-assisted web interviewing surveying technique with the use of a self-administered questionnaire. Results: Among 408 respondents (56.9% women), with a median age of 32 years, significantly more admitted to having unprotected sexual contact with a casual partner while in the UK (p < 0.0001) than while in Poland; more were engaged in sex after the use of recreational drugs and alcohol (p < 0.0001 and p = 0.001 respectively). Being a male was associated with greater odds of unprotected sex, sex after the use of alcohol, and having multiple partners. Being single and having only been a resident for a short time in the UK, presenting a lower self-esteem, were predictors of unprotected sex. A total of 19.6% of the respondents admitted to having been tested while in Poland, a lower (p < 0.0001) frequency than while in the UK (49.5%); this referred to both genders; 1.2% (95% CI: 0.79-2.83%) reported that they were HIV positive. Conclusions: Migration can create a vulnerability to STIs, especially for single male migrants with low self-esteem, staying in the UK for less than two years. The results point to strengthening strategies which help reduce high risk sexual behavior among Polish migrants, and to introduce interventions to promote an awareness of HIV sero-status.

Proinflammatory cytokine (IL-1beta, IL-6, IL-12, IL-18 and TNF-alpha) levels in sera of patients with subacute cutaneous lupus erythematosus (SCLE).

Subacute cutaneous lupus erythematosus (SCLE) is a subset of lupus erythematosus that identifies patients with clinically recognized erythematous, nonscarring lesions, photosensitivity and serologic abnormalities. Anti-Ro (SS-A) antibodies are considered to be a typical immunopathologic marker of SCLE. Autoimmune diseases have been also characterized by the disturbances in the cytokine network. The aim of this study was to compare the concentrations of proinflammatory cytokines (IL-1beta, IL-6, IL-12, IL-18 and TNF-alpha) in serum of ANA-positive (antibody against nuclear antigen) and ANA-negative patients with SCLE. Sera samples were collected from 15 patients with SCLE (9 ANA-positive and 6 ANA-negative ones). The preliminary identification of autoantibodies as well as their titers was determined on HEp-2 cells using IIF method. Western blotting (EUROIMMUN) was applied to verify the results of IIF. Proinflammatory cytokine concentrations in the patients' sera samples were determined by enzyme-linked immunosorbent assay (ELISA) (Bender MedSystems). The levels of IL-12 were higher in ANA-positive patients than in ANA-negative subgroups [median (interquartile range), 330 pg/ml (128-708 pg/ml) versus 39.4 pg/ml (31.25-80 pg/ml)]. Similar differences were observed in the level of IL-18 [median (interquartile range), 508.4 pg/ml (180-1222 pg/ml) versus 100.5 pg/ml (78.1-154 pg/ml)]. The differences in TNF-alpha levels between the groups of ANA-positive and ANA-negative patients were at the verge of statistical significance, p<0.05. The sera levels of IL-1beta and IL-6 were low and of no significant difference concerning the ANA-positive and ANA-negative subgroups. Since serum levels of IL-12 and IL-18 were higher in ANA-positive patients than in ANA-negative patients, these cytokines might play an important role in the inflammatory process in SCLE.

Nurses and occupational exposures to bloodborne viruses in Poland.

STUDY OBJECTIVE: To record descriptions of occupational exposures to blood, determine factors predictive of exposure, and identify interventions that might reduce the frequency of exposure. DESIGN: An analytic, cross-sectional survey. STUDY POPULATION: A total of 601 nurses from surgical wards, operating rooms, and emergency departments. STUDY INSTRUMENT: An anonymous questionnaire developed by the authors on the basis of previously published guidelines was distributed between January and March 2003. SAMPLING: Random, with 18 hospitals selected from 2 urban and rural locations. RESULTS: Almost half of respondents reported having had at least 1 puncture injury during the preceding year, 1 in 5 had exposure via mucous membranes, and more than half had worked at least once with a recent abrasion or cut on their hands. The number of injuries was independent of age (P=.26), duration of practice (P=.21), and workplace setting (P=.78). The percentage of nurses without percutaneous exposure during the preceding year was significantly higher in the group that received special HIV/AIDS training than in the group that did not (95% confidence interval, 5.8-24.1%; P<.002). The most recent exposure was primarily caused by hollow-bore needles, involved the palm and fingers II-V, was self-inflicted, took place during an elective procedure, and was not reported to the hospital's infection control center by 74% of respondents. The most common reason for not reporting the exposure (38% of cases) was the conviction that the source patient was not infected. CONCLUSIONS: Because of the large number of occupational exposures to blood, especially those due to injuries with hollow-bore needles, nurses should adopt more adequate behavioral strategies to prevent the transmission of blood-borne pathogens. Policies for providing adequate education programs tailored to encourage nurses to report all exposures are urgently required.

The NOD2 3020insC mutation and the risk of colorectal cancer.

Several predispositions to colorectal cancer have been identified, but little is known about genetic susceptibilities to disease in older persons. Colorectal cancer is a risk in Crohn's disease and is believed to be associated with an inappropriate inflammatory response. Recently, the NOD2 gene has been associated with Crohn's disease, which further strengthens the notion that the inflammatory response plays a crucial role in this disease. Several mutations have been identified in the NOD2 gene, which appear with significantly higher frequency in patients with the disease. One such mutation (3020insC) is believed to be clearly causative because it results in a prematurely truncated protein with a predicted reduction in functional efficiency. In this report, we have examined the frequency of the 3020insC mutation in a series of 856 individuals including 556 patients with colorectal cancer. The frequency of the 3020insC mutation in a consecutive series of 250 non-hereditary nonpolyposis colorectal cancer patients >50 years of age was significantly elevated compared with the control population (odds ratio, 2.23; P = 0.0046). The results indicate that NOD2 may be a predisposing factor to colorectal cancer characterized by an older average age of disease onset in persons who do not harbor any other genetic predisposition to disease.

[Permanent local nerve injuries after carotid endarterectomy]. / Trwale miejscowe uszkodzenia nerwów po udroznieniu tetnicy szyjnej wewnetrznej.

UNLABELLED: Functional assessment of nerves, especially motor rami of cranial nerves, in patients at postoperative period after carotid endarterectomy (CEA), is particularly important in case of necessity of contralateral carotid artery surgery. Bilateral damage to recurrent laryngeal or hypoglossal nerve is a potentially life-threatening complication. Sensory disturbances due to intraoperative injuries of cervical plexus branches may cause residual discomfort in numerous patients. The aim of this study was the assessment and comparison of frequency of persistent (for more than 12 months postoperatively) manifestations of cranial and cervical nerves injuries in patients after CEA performed either in the standard or eversion technique. A prospective study evaluating cranial and cervical nerves dysfunction after carotid endarterectomies in 144 out of 193 patients operated on from January 1999 until June 2001 was undertaken at the Department of General and Vascular Surgery, Pomeranian Medical University in Szczecin, Poland. CEA was performed in the standard way (i.e. by primary closure) in 92 patients, while 52 others were operated on by eversion technique. Neurological examination with careful functional assessment of cranial nerves: V, VII, IX, X, XII and cervical plexus, was performed according to a standard protocol within two follow-up periods: 3 to 6 and 12 to 18 months after discharge from the hospital. RESULTS: Dysfunction of recurrent laryngeal nerve and hypoglossal nerve were registered 12 to 18 months after CEA with similar incidence of 1.4%. There was no sign of residual damage to other cranial nerves. Sensory disturbances in the area supplied by cervical plexus, mainly transverse cervical and greater auricular nerve, were diagnosed in 26% of patients. There were no statistically significant differences in local neurological complication rates between patients operated on according to standard and eversion procedures. CONCLUSIONS: 1. Permanent damage of cranial nerves refers to small group of patients after carotid endarterectomy and concern predominantly recurrent laryngeal nerve and hypoglossal nerve. 2. Majority of local neurological complications are injuries to cervical plexus branches. 3. Eversion carotid endarterectomy is not related to higher incidence of local neurological deficits compared to standard procedure.

[Objective retinal nerve fiber laser assessment by scanning laser polarimetry in patients with chiasmal compression]. / Obiektywna ocena zmian warstwy wlókien nerwowych siatkówki za pomoca badania GDx u pacjentów z uciskiem dróg wzrokowych.

PURPOSE: To assess the evaluation ability of retinal nerve fiber layer (RNFL) in patients with visual tracts' compression and to assess the correlation between visual field loss and changes in RNFL. MATERIAL AND METHODS: Polarimetric RNFL analysis (scanning laser polarimeter- NFA/GDx, software version 1.0.16, LDT(inc)) and kinetic perimetry were done in 41 eyes with different types of optic chiasma compression and in 40 healthy eyes, age matched controls. RESULTS: In eyes with optic chiasma compression most of the GDx parameters were statistically different from the control group (P<0.05). In eyes with normal visual fields and with optic chiasma compression most of GDx parameters were statistically different from the other analyzed groups. CONCLUSIONS: GDx may be a helpful tool in diagnosis of optic chiasma diseases. GDx is a useful visual prognostic indicator in the preoperative assessment of optic chiasma compression. Objective RNFL assessment is especially important in patients with serious visual field loss and poor visual acuity.
