Supraglottic Airway Device to Improve Ventilation Success and Reduce Pulmonary Aspiration during Cardio-Pulmonary Resuscitation by Basic Life Support Rescuers: A Randomized Cross-over Human Cadaver Study.

OBJECTIVES: Early airway management during cardiopulmonary resuscitation (CPR) prevents aspiration of gastric contents. Endotracheal intubation is the gold standard to protect airways, but supraglottic airway devices (SGA) may provide some protection with less training. Bag-mask ventilation (BMV) is the most common method used by rescuers. We hypothesized that SGA use by first rescuers during CPR could increase ventilation success rate and also decrease intragastric pressure and pulmonary aspiration. METHODS: We performed a randomized cross-over experimental trial on human cadavers. Protocol A: we assessed the rate of successful ventilation (chest rise), intragastric pressure, and CPR key time metrics. Protocol B: cadaver stomachs were randomized to be filled with 300 mL of either blue or green serum saline solution through a Foley catheter. Each rescuer was randomly assigned to use SGA or BMV during a 5-minute standard CPR period. Then, in a crossover design, the stomach was filled with the second color solution and another 5-minute CPR period was performed using the other airway method. Pulmonary aspiration, defined as the presence of colored solution below the vocal cords, was assessed by a blinded operator using bronchoscopy. A generalized linear mixed model was used for statistical analysis. RESULTS: Protocol A: Forty-eight rescuers performed CPR on 11 cadavers. Median ventilation success was higher with SGA than BMV: 75.0% (IQR: 59.8-87.3) vs. 34.7% (IQR: 25.0-50.0), (p = 0.003). Gastric pressure and differential (maximum minus minimum) gastric pressure were lower in the SGA group: 2.21 mmHg (IQR: 1.66; 2.68) vs. 3.02 mmHg (IQR: 2.02; 4.22) (p = 0.02) and 5.70 mmHg (IQR: 4.10; 7.60) vs. 8.05 mmHg (IQR: 5.40; 11.60) (p = 0.05). CPR key times were not different between groups. Protocol B: Ten cadavers were included with 20 CPR periods. Aspiration occurred in 2 (20%) SGA procedures and 5 (50%) BMV procedures (p = 0.44). CONCLUSION: Use of SGA by rescuers improved the ventilation success rate, decreased intragastric pressure, and did not affect key CPR metrics. SGA use by basic life support rescuers appears feasible and efficient.

Reconstruction, oversewing, or taking the anastomosis down - which surgical intervention is most potent in the treatment of anastomotic leaks following colorectal resections?

PURPOSE: Anastomotic leak (AL) following colorectal resections can be treated interventionally. However, most cases require surgical intervention. Thus, several surgical techniques are available, which intend to affect the further course positively. The aim of this retrospective analysis is to determine which surgical technique proves to have the biggest potential in reducing the morbidity and mortality as well as to minimize the need of re-interventions after AL. METHODS: All patients with a history of AL following colorectal resection between 2008 and 2020 were analyzed. Patient's outcomes following surgical treatment of AL, including morbidity and mortality, clinical and para-clinical (laboratory examinations, ultrasound, and CT-scan) detection of AL recurrence, re-intervention rate, and the length of hospital stay were documented and correlated with the surgical technique used (e.g. simply over-sewing the AL, over-sewing the AL with the construction of a protective ileostomy, resection and reconstruction of the anastomosis, peritoneal lavage and transanal drainage, or taking the anastomosis down and constructing an end stoma). RESULTS: A total of 2,724 colorectal resections were documented. Grade C AL occurred in 92 (4.4% AL occurrence-rate) and 31 (7.2% AL occurrence-rate) cases following colon and rectal resections, respectively. The anastomosis was not preservable in 52 and 17 cases following colon and rectal resections, respectively. Therefore, the anastomosis had been taken down and an end-stoma had been constructed. Over-sewing the AL with the construction of a protective ileostomy had the highest anastomosis preservation rate (14 of 18 cases) and lowest re-intervention rate (mean value of 1.5 re-interventions) following colon and rectal resections (7 of 9 cases; mean value, 1.5 re-interventions). CONCLUSION: In cases where an AL is preservable, over-sewing the anastomosis and constructing a protective ileostomy has the greatest potential for positive short-term outcomes following colorectal resections.

Necessity of routine perioperative epidural catheter placement in laparoscopic colorectal resections: a retrospective data analysis.

PURPOSE: Whether epidural anesthesia leads to further improvement in the postoperative course of colorectal procedures is under discussion. The aim of this study was to evaluate the effects of minimally invasive colorectal oncological interventions without epidural anesthesia (EDA). METHODS: This retrospective data analysis included the clinical data of all patients who underwent minimally invasive oncological colorectal resection at our clinic between January 2013 and April 2019. Of 385 patients who met the inclusion criteria, 183 (group I; 47.5% of 385) received EDA, and 202 (group II; 52.5% of 385) received transversus abdominis plane block instead. The relevant target parameters were evaluated and compared between the groups. The postoperative complications were graded according to the Clavien-Dindo classification. RESULTS: The patients in group I (n=183; women, 77; men, 106; age 66.8 years) were younger (p=0.0035), received a urinary catheter more often (99.5% versus [vs.] 28.2% p<0.001), required longer, more frequent arterenol treatment (1.1 vs. 0.6 days; p<0.001), and had a longer intermediate care unit stay than those in group II (2.8 vs. 1.1 days; p<0.001). Postoperative pain levels were not significantly different between the groups (p=0.078). The patients in group I were able to ambulate later than those in group II (4 vs. 2 days; p<0.001). The difference in the postoperative day of the first defecation was not significant between the groups (p=0.236). The incidence of postoperative complications such as bleeding (p=0.396), anastomotic leaks (p=0.113), and wound infections (p=0.641) did not differ between the groups. The patients in group I had significantly longer hospital stays than those in group II (12.2 vs. 9.4 days; p<0.001). CONCLUSION: EDA can be safely omitted from elective minimally invasive colorectal resections, and its omission is not accompanied by any relevant disadvantages to the patient.

Laparoscopic rectal resection without epidural catheters-does it work?

PURPOSE: Placement of an epidural catheter (EC) in colorectal resections is still recommended as a valid measure to achieve a low level of pain. However, EC is associated with increased invasiveness and with an increased risk of bladder emptying disorders and a decrease in blood pressure, which all relate to delayed mobilization. Preliminary data shows that EC placement may not be necessary for laparoscopic colon resections. The aim of this prospective study was to investigate how the omission of EC placement influences short-term postoperative outcomes in laparoscopic rectal resections. METHODS: All laparoscopic rectal resections occurring between 2013 and 2020 were prospectively examined. Resections from January 2013 to February 2018 (group A) were compared with resections from March 2018 to December 2020 (group B; after the internal change of the perioperative pain regime). In addition to EC placement, the other target parameters of our study were urinary catheter placement during the inpatient stay, postoperative pain > 3 days on a numerical rating scale (NRS), mobilization in the first 5 postoperative days, time until the first postoperative bowel movement, postoperative complications according to Clavien-Dindo, intermediate care unit stay (IMC stay) in days, and hospital length of stay in days. RESULTS: In the entire study period, 221 laparoscopic rectal resections were performed: 122 in group A and 99 resections in group B. The frequency of EC placement and urinary catheter placement, postoperative IMC stay, and hospital length of stay was significantly lower in group B (p < 0.05). The postoperative mobilization of patients in group B was possible more quickly. There were no differences in the level of pain, time until the first postoperative bowel movement, and postoperative complications according to Clavien-Dindo. CONCLUSION: Omission of EC placement in laparoscopic rectal resections led to faster mobilization, a shorter IMC stay, and a shorter hospital stay without increasing the pain level. Postoperative complications did not change when an EC was not placed. Therefore, routine EC placement in laparoscopic rectal resections is unnecessary.

Ptychographic characterisation of polymer compound refractive lenses manufactured by additive technology.

The recent success in the development of high-precision printing techniques allows one to manufacture free-standing polymer structures of high quality. Two-photon polymerization lithography is a mask-less technique with down to 100 nm resolution that provides full geometric freedom. It has recently been applied to the nanofabrication of X-ray compound refractive lenses (CRLs). In this article we report on the characterization of two sets of CRLs of different design produced by two-photon polymerization-induced lithography.

Towards X-ray transient grating spectroscopy.

The extension of transient grating spectroscopy to the x-ray regime will create numerous opportunities, ranging from the study of thermal transport in the ballistic regime to charge, spin, and energy transfer processes with atomic spatial and femtosecond temporal resolution. Studies involving complicated split-and-delay lines have not yet been successful in achieving this goal. Here we propose a novel, simple method based on the Talbot effect for converging beams, which can easily be implemented at current x-ray free electron lasers. We validate our proposal by analyzing printed interference patterns on polymethyl methacrylate and gold samples using ∼3 keV X-ray pulses.

Lymph node dissection in endometrial cancer and clinical outcome: A population-based study in 5546 patients.

BACKGROUND: According to current treatment guidelines, comprehensive surgical staging procedures in endometrial cancer confined to the uterus depend on uterine risk factors: a systematic lymph node dissection (LND) is recommended in high risk patients and should be omitted in low risk patients. Its role in intermediate and high intermediate risk patients is inconclusive. The aim of this analysis was to review the implementation of this risk-adopted strategy. MATERIALS AND METHODS: Data were provided by the population-based Munich Cancer Registry. Patients with endometrial cancer diagnosed between 1998 and 2016 were included. RESULTS: Of 5446 eligible patients, 58.5%, 30.1% and 11.4% belonged to the low risk, intermediate/high-intermediate and high risk group, respectively. Lymph node dissection was performed in 20.2%, 53.0% and 63.7% within these groups. Lymph node involvement was diagnosed in 1.7%, 9.6% and 19.3%, respectively. Within these risk groups, there was no significant difference in the time to local recurrence, lymph node recurrence or distant metastases between patients with and without LND. After adjusting for age and comorbidity-status, no significant difference in overall survival was found. CONCLUSIONS: The application of a risk-adopted management of LND in early endometrial cancer in real-life is associated with a high rate of surgical under- and overtreatment. Corresponding survival data do not show a significant benefit of a systematic lymph node dissection. In order to improve the management and outcome of early endometrial cancer in the future, prospective trials, new surgical concepts and prognostic markers will be primary and necessary.

[Half-Dose Verteporfin Photodynamic Therapy (hdPDT) in the Treatment of Central Serous Chorioretinopathy]. / Photodynamische Therapie mit halber Verteporfin-Dosis zur Behandlung der Chorioretinopathia Centralis Serosa.

BACKGROUND: To estimate the efficacy and safety profile of half-dose photodynamic therapy (hdPDT) for treating central serous chorioretinopathy (CSC). PATIENTS AND METHODS: An interventional, retrospective case series of patients with CSC (symptoms ≧ 3 months) receiving half-dose PDT (3 mg/m2 verteporfin). The ophthalmic examination at baseline and at 8 and 16 weeks after treatment included slit-lamp biomicroscopy, indirect ophthalmoscopy, measurement of intraocular pressure (IOP), ETDRS best-corrected visual acuity (BCVA), Amsler grid screening and contrast visual acuity (CVA). Fluorescein angiography (FA), autofluorescence (FAF) and optical coherence tomography (OCT) were measured at each visit. Central macular thickness (CMT) was measured automatically. RESULTS: 12 eyes of 12 patients (10 male and 2 female patients; mean age 46.6 ± 7.91 years) were included in this study. Anatomical resolution was obtained in 10 eyes (83.4 %) at week 16, but 2 eyes (16.6 %) exhibited persistent SRD throughout the follow-up period. Baseline CMT decreased from initially 330.1 µm ± 131.3 to 205.6 µm ± 97.6 (p = 0.034) at week 8 and to 220.3 µm ± 120.1 (p = 0.05) at week 16. Visual acuity (number of total letters read) significantly improved from initially 82.8 ± 11.5 to 86.8 ± 13.9 at week 8 and 91.3 ± 13.8 at week 16 (p = 0.012). Contrast visual acuity (calculated decimal visual acuity) significantly improved from initially 0.14 ± 0.09 to 0.38 ± 0.28 (p = 0.002) at week 16. After therapy, no significant changes in RPE could be detected with FAF and no ocular adverse events were observed. CONCLUSION: PDT with half-dose verteporfin resulted in reduced leakage in FA, enhanced visual acuity and resolution of subretinal fluid in OCT in patients with CSC, with no detected side effects of treatment.

Increasing the field of view in grating based X-ray phase contrast imaging using stitched gratings.

Grating based X-ray differential phase contrast imaging (DPCI) allows for high contrast imaging of materials with similar absorption characteristics. In the last years' publications, small animals or parts of the human body like breast, hand, joints or blood vessels have been studied. Larger objects could not be investigated due to the restricted field of view limited by the available grating area. In this paper, we report on a new stitching method to increase the grating area significantly: individual gratings are merged on a carrier substrate. Whereas the grating fabrication process is based on the LIGA technology (X-ray lithography and electroplating) different cutting and joining methods have been evaluated. First imaging results using a 2×2 stitched analyzer grating in a Talbot-Lau interferometer have been generated using a conventional polychromatic X-ray source. The image quality and analysis confirm the high potential of the stitching method to increase the field of view considerably.

A chemiluminescent light system in combination with toluidine blue to assess suspicious oral lesions-clinical evaluation and review of the literature.

OBJECTIVES: The aim of the study was an evaluation of an acetic acid wash and chemiluminescent light system in combination with toluidine blue in order to detect visual identified, potentially malignant lesions. MATERIALS AND METHODS: Forty-four patients with 50 oral lesions of primary uncertain visible dignity were included. Next to a clinical examination, a screening with ViziLite® (VL) as well as toluidine blue (TB; together ViziLite® Plus (VLP)) was conducted. Histopathology served as gold standard and sensitivity (SE), specificity (SP), positive as well as negative predictive value (PPV, NPV) was calculated descriptively. Additionally, a PubMed literature search using the key words "ViziLite" and "chemiluminescence oral cancer" was conducted. RESULTS: Histological diagnosis showed 40 lesions of reactive/inflammatory nature, moderate dysplasia (n = 3) and oral squamous cell carcinoma (OSCC n = 7). All OSCCs and one dysplasia were identified correct via clinical diagnosis (SE 90 %, SP 100 %, PPV 100 %, NPV 97.5 %). VL examination could show all malignancies with low specificity (SE 100 %, SP 30 %, PPV 26 %, NPV 100 %). TB and VLP were positive in all cases of cancer and in one case of inflammation (SE 80 %, SP 97.5 %, PPV 89 %, NPV 95 %). In the review, eight clinical trials with similar results were included. CONCLUSIONS: The adjunct of TB to VL reduces the number of false positives without increasing the rate of false negatives. CLINICAL RELEVANCE: Clinical evidence to justify the additional cost of the system for diagnosis of suspicious lesions is weak. However, for the potential role of VLP in detection of lesions not otherwise identified in the visual exam in general dental practice further studies are required.

Managing outbreaks of invasive species--a new method to prioritize preemptive quarantine efforts across large geographic regions.

In pest risk assessment it is frequently necessary to make time-critical decisions regarding management of expanding pest populations. When an invasive pest outbreak is expanding rapidly, preemptive quarantine of areas that are under imminent threat of infestation is one of only a few available management tools that can be implemented quickly to help control the expansion. The preemptive quarantine of locations that surround an infested area also acts as a safeguard to counteract the risk of failed detections of the pest in field surveys. In this paper, we present a method that assesses the suitability of preemptive quarantine measures at the level of small geographical subdivisions (U.S. counties). The cost of a preemptive quarantine in a given county is weighed against the protective benefit of delaying the spread of an outbreak to other neighboring counties. We demonstrate the approach with a decision support model that estimates the suitability of preemptive quarantine across multiple counties that surround areas infested with the emerald ash borer (Agrilus planipennis Fairmaire (EAB), Coleoptera: Buprestidae), an emerging major threat to ash tree species (Fraxinus spp.) in North America. The model identifies the U.S. counties where the installation of preemptive quarantine would most effectively slow the spread of EAB populations and reduce risk to high-value areas.

[Can Postoperative Accelerated Lens Opacification be Limited by Lying in "Face-Down Position" after Vitrectomy with Gas as Tamponade?]. / Kann eine postoperativ beschleunigte Linsentrübung nach einer Pars-plana-Vitrektomie mit Gas als Tamponade durch eine konsequente "Gesicht-nach-unten-Lagerung" vermieden werden?

BACKGROUND: Developing a post-operative cataract after pars-plana vitrectomy (ppV) or core pars-plana vitrectomy (cppV) with gas as tamponade within 6 to 12 months is a common complication and is mostly accepted as unavoidable. Often a combined cataract-ppV surgery in the first place is recommended. The main goal of this study was to analyse the effects of a "face-down positioning" ("fdp") on the lens transparency and the phaco rate. By using the positive experience of an ergonomic body positioning it should be possible to improve the compliance during the period of "fdp" after surgery. METHODS: During the study period of up to 24 months, we observed in a prospective, controlled, clinical and randomised pilot study 30 patients who all had undergone a ppV/cppV with sulfur hexafluoride gas tamponade (SF6 25 %). All patients of the supported group (SG) and the control group (CG) were requested to keep their face consequently downwards until the gas bubble was resorbed completely in order to avoid a direct contact with the lens. The real time in "fdp" in hours per day (24 hours) and the grade of lens opacification was documented pre- and postoperatively using a Pentacam HR (Oculus, Wetzlar). RESULTS: The compliance of patients tested measuring the real time of "fdp" in hours per day varied largely (SG: 19.5/24; CG: 5.5/24; p < 0,0001). Cataract development was found to be directly related to the real time of "fdp". A cataract surgery was necessary mainly in the non-supported group (SG: 4/15; CG:12/15; p = 0.012). There was no lens opacification in the supported group after performing the "fdp" for at least 20 hours daily until the resorption of the gas bubble was completed. This result did not correlate with the age of the patient. CONCLUSION: With the help of sufficient support at the disposal of the patients, it is possible to significantly improve the compliance during the period of "fdp" after surgery. In order to get a safe and painless "fdp" in bed, an ergonomic body positioning is necessary (Schaefer 2012). By practicing the "fdp" until the gas bubble is completely resorbed, the risk of developing a postoperative cataract can be reduced significantly. Provided there is a good compliance to "fdp", the gas bubble can cause the desired tamponade effect even when using shorter acting gases. By performing a consistent "fdp" it is possible to accelerate the healing process and avoid reoperations. Hereby it should even be possible to use an SF6-air mix or optionally simply air as tamponade.

A novel immunofluorescence flow cytometry technique detects the expansion of brown tides caused by Aureoumbra lagunensis to the Caribbean Sea.

During the past 3 decades, brown tides caused by the pelagophytes Aureococcus anophagefferens and Aureoumbra lagunensis have caused ecological and economic damage to coastal ecosystems across the globe. While blooms of A. lagunensis had previously been confined to Texas, in 2012, an expansive brown tide occurred on Florida's East Coast, causing widespread disruption within the Indian River and Mosquito Lagoons and generating renewed interest in this organism. A major impediment to detailed investigations of A. lagunensis in an ecosystem setting has been the absence of a rapid and reliable method for cell quantification. The combination of their small size (3 to 5 µm) and nondescript extracellular features makes identification and enumeration of these cells with conventional methods a challenge. Here we report the development of an immunological-based flow cytometry method that uses a fluorescently labeled antibody developed against A. lagunensis. This method is species specific, sensitive (detection limit of 1.5 × 10(3) cells ml(-1)), precise (1% relative standard deviation of replicated samples), and accurate (108% ± 8% recovery of spiked samples) over a wide range of cell concentrations. Furthermore, this method effectively quantifies A. lagunensis in both glutaraldehyde- and formalin-preserved samples, yields a high throughput of samples (∼35 samples h(-1)), and is cost-effective, making it an ideal tool for managers and scientists. This method successfully documented the recurrence of a brown tide bloom in Florida in 2013. Bloom densities were highest in June (>2.0 × 10(6) cells ml(-1)) and spanned >60 km from the Ponce de Leon inlet in the northern Mosquito Lagoon south to Titusville in the Indian River Lagoon. Low levels of A. lagunensis cells were found >250 km south of this region. This method also quickly and accurately identified A. lagunensis as the causative agent of a 2013 brown tide bloom in Guantanamo Bay, Cuba, and thus should prove useful for both quantifying the dynamics of ongoing blooms of A. lagunensis as well as documenting new outbreaks of this harmful alga.

Associations between single-nucleotide polymorphisms of the VEGF gene and long-term prognosis of oral squamous cell carcinoma.

INTRODUCTION: Functional polymorphisms (SNPs) of the vascular endothelial growth factor (VEGF) are associated with the incidence of oral squamous cell carcinoma (OSCC). An impact of VEGF-SNPs on prognosis of OSCC patients seems possible. Therefore, correlations between prognostic parameters of OSCC patients and five VEGF-SNPs were determined. MATERIALS AND METHODS: In a retrospective long-term study, in 113 OSCC patients that underwent curative resections, five VEGF-SNPs (-1154 G/A, +405 G/C, +936 C/T, -2578 C/A, and -460 C/T) were analyzed. Associations between SNPs and prognosis (incidence of local recurrent disease, second cancer, metastases, death, total disease-free survival) were examined. RESULTS: After a mean follow-up time of 57.6 months, 32 patients had local recurrences; 15 patients had second cancer, 15 patients metastases, and 23 patients died. The mean disease-free survival was 43.1 months. A significant increased incidence of OSCC in smokers with the VEGF -2578 A/C and -460 C/T SNP was seen (each P < 0.0001). In univariate analysis, patients with advanced OSCCs (T > 2 or N > 0) together with the -1154 A/A allele had a significant worse survival and a worse disease-free survival (both P < 0.04). The same was seen for the +405 G/G SNP (both P = 0.002). In multivariate analysis, only the negative influence of the +405 G/G SNP on survival in advanced OSCCs (T > 2) could be confirmed (P = 0.002). DISCUSSION: Possible reciprocal interactions between smoking and VEGF-SNP function were observed. Multivariate analysis confirmed the VEGF +405 G/G genotype to be associated with poor survival in advanced OSCCs; a further use of this haplotype as biomarker has to be discussed.

[Health promotion within health care - analysis of employees' smoking habits, consequences for patient care and resources for future smoking cessation initiatives]. / Gesundheitsförderung im Gesundheitswesen - Analyse der Rauchgewohnheiten der Mitarbeiter, Konsequenzen für die Patientenbehandlung und Ressourcen für zukünftige Tabakentwöhnungsinitiativen.

Smoking is still one of the most dangerous and avoidable health risks. This study "Healthy air at work" analysed smoking habits, state of change, the influence of the diagnosis F.17.0 in patient treatment and estimation of subjective workloads and personal resources in health-care workers. Almost 2 000 questionnaires were analysed. 19.9% of this study population were smokers, while 26.4% were considered to be heavy or very heavy smokers. Half of the current smokers were willing to change, while the majority had already tried to quit multiple times. The most important motive to stop smoking was fear of consequences (44.4%), followed by other reasons (42.3%) (e. g., pregnancy) and expenses (33.9%). Protection against second-hand smoke was estimated mostly as very relevant, especially for patients. Being a role model in terms of tobacco consumption seems to be important for health-care workers. 61.3% of all health-care workers stated that patients' nicotine dependency had been diagnosed and out of these 46.5% say it is a relevant factor in therapy. 60% of all interviewed employees evaluated themselves as working quantitatively under heavy and very heavy workloads, while 20% had to deal with high qualitative challenges. In terms of future work ability and personal resources 75% were considerably optimistic. We did not find any relation in terms of workloads and smoking habits. Rather few health-care workers used nicotine replacement therapy during former cessation trials. Health-care workers could play an important role in the treatment and prevention of smoking dependency. This potential is not used to its full extent up to now.

[Midwives and smoking--attitudes, smoking status and counselling competence in the course of training]. / Hebammen und Rauchen--Einstellungen, Rauchstatus und Beratungskompetenz im Ausbildungsverlauf.

Tobacco consumption is a major public health threat. Midwives can contribute to the reduction of tobacco use among pregnant women and young families. It can be assumed that personal smoking behaviour and knowledge of harmful effects influences counselling activities. The aim of this study was to assess smoking status, nicotine dependency and the will to change of midwifery students in german-speaking countries. Broad data on this population is not available so far. In 2010, a self-administered questionnaire survey was conducted among Austrian, German and Swiss midwifery schools. Sociodemographic characteristics, smoking habits, personal attitudes towards smoking, knowledge of cessation strategies, perceived self-efficacy and competence to counsel pregnant women regarding their smoking habits of midwifery trainees were examined. 1 126 students and 38 teaching midwives answered this questionnaire (RR=61.8%). 22.7% are daily or occasional smokers. 6.8% have to be considered as medium and heavy smokers. 98.1% consider cessation counselling for pregnant and breast-feeding women as a midwife's task, while 76.5% feel competent enough to do so. 75.5% rate cessation counselling through midwives as effective stop-smoking procedures compared to blurry knowledge on related health risks and effective stop-smoking strategies. The self-reported smoking prevalence is considerably lower than in previous studies and other populations. Knowledge of harmful effects and of effective treatment options needs improvement. Counselling competence needs to be included in a broader way in midwifery curricula.
