ABSTRACT

INTRODUCTION: The effects of air-polishing on exposed root dentin surfaces are largely unknown, as there are only few studies which show heterogeneous results. Thus, this study was to investigate roughness changes of exposed dentin surfaces after air-polishing and the influence of subsequent polishing with cup and paste. METHODS: Totally 54 teeth with exposed root dentin surfaces were treated using a split-mouth design by either air-polishing with erythritol and a rubber cup with polishing paste on the test side, or rubber cup and paste alone. Teeth were finally cleaned using a sonic tooth brush. Impressions were taken at relevant time points and replicated using epoxy resin. The resulting casts were profilometrically analysed to obtain the average surface roughness (sRa) and maximum peak-to-valley height (sRz), which are given as the mean ± standard deviation in µm. RESULTS: After air-polishing, in comparison to the baseline, there was a slight but significant increase in sRa (0.168 ± 0.143, p < 0.001), but sRz did not change (-0.471 ± 4.857, p = 0.936). Subsequent polishing with cup and paste and cleaning with a sonic toothbrush did not reduce the surface roughness (sonic toothbrush-air-polishing, sRa -0.044 ± 0.081, p = 0.218; sRz -0.551 ± 3.563, p = 0.903). CONCLUSION: The use of erythritol led to a slight increase in the roughness of the dentin surface, which was not reduced by polishing with a cup and paste. Polishing paste did not seem to conceal surface irregularities.

ABSTRACT

This ex vivo study aimed to investigate surface roughness and substance loss after treatment with different professional cleaning methods and to determine whether subsequent polishing with a rubber cup and polishing paste is necessary. Samples (flat and natural surfaces) of human enamel and dentin were prepared (baseline) and treated with either a curette, air-polishing with erythritol, a rubber cup and polishing paste, or a combination thereof (treatment). Subsequently, all samples were immersed in an ultrasonic bath (ultrasonic) to remove residues from the treatment procedures. The surface roughness values sRa and sRz as well as tissue loss were measured profilometrically. Linear regression models were used to compare group differences (roughness and loss) considering the corresponding baseline value. The significance level was set at p<0.05. sRa increased significantly after treatment with curettes or air-polishing with erythritol in both enamel (p<0.001) and dentin (p<0.001) of flat samples. The same effect was observed for sRz in dentin (p<0.001) but not for enamel compared to negative control. Polishing with a rubber cup and paste alone had no significant effect on roughness values. When combined with other treatments, the effect of curette or air-polishing with erythritol dominated the effect. In enamel, none of the tested methods led to measurable tissue loss. In dentin, air-polishing with erythritol caused ≤50% tissue loss compared to the curette. Conclusively, for enamel, treatment effects on roughness were measurable but of limited clinical relevance. For dentin, air-polishing resulted in a smaller but insignificant roughness increase and less tissue loss compared to the curette. Polishing with a rubber cup and paste did not affect surface roughness. Regarding the clinical application, the use of air-polishing seems to be a less invasive procedure than using a curette; polishing with rubber cup and paste offers no advantage in terms of reducing roughness as a final procedure.

ABSTRACT

INTRODUCTION: Early discharge holds several advantages and seems safe after planned cesarean section among low-risk women. However, breastfeeding rates are lower after cesarean section. Thus, concern has been raised that early discharge among these women may affect breastfeeding even further. Therefore, we aimed to assess the effect of early discharge the day after planned cesarean section on breastfeeding, among parous women when a home-visit by a midwife was provided the day after discharge. METHODS: We conducted a secondary analysis of a randomized trial. Parous women (n=143) planned for cesarean section were allocated to either discharge within 28 hours after planned cesarean section followed by a home visit the day after (early discharge) or discharge at least 48 hours after planned cesarean section (standard care). The participants filled in questionnaires approximately 2 weeks before delivery and 1 week, 4 weeks, and 6 months postpartum. RESULTS: The proportions of women initiating breastfeeding were 84% versus 87% (early discharge vs standard care). After 6 months, 23% versus 21% were exclusively breastfeeding, while 29% versus 42% were partially breastfeeding. The mean duration of exclusive breastfeeding was 3.4 months (SD=2.3) in both groups. None of these differences was statistically significant. In both groups, the women's breastfeeding self-efficacy score before cesarean section correlated with the duration of breastfeeding. After 4 weeks, low-score rates were 28% versus 30%. CONCLUSIONS: Early discharge with follow-up home visits by a midwife after planned cesarean section in parous women is feasible without compromising breastfeeding.

ABSTRACT

Background: The development in teaching dental education toward ever greater digitization has gained enormous momentum in the last 2 years due to the pandemic. However, acceleration is not synonymous with improvement, especially from the learners' point of view. Therefore, the aim of this survey among students of dentistry was to determine which digital learning strategies and which media are preferred. Method: Undergraduate students of clinical semesters (6th to 9th) in dental medicine during at the University of Freiburg participated in an online-survey. Questions were asked about personal learning strategies for and experience with using digital media for private and educational reasons. Furthermore, students were asked which digital learning formats they preferred for different learning phases. Results: Students (N=148) are experienced in using digital media for learning. They prefer classical media (such as textbooks and lectures) for acquiring basic theoretical knowledge and mention digital teaching formats more in relation to practical training and complex treatment procedures. 67% prefer learning alone and 90% rate visualizations as helpful for learning. 78% report, that they feel well supported in the learning process by digital media and 83% agree that e-learning offerings are a quality factor for university teaching. 82% state e.g. that the growing range of online content allows a more flexible approach to face to face-teaching, enriches classroom teaching (78%) and helps organize one's own study (79%). Conclusion: Students have a positive attitude towards the use of digital media, especially when it comes to having more time available for practical exercises. They also see an advantage in the fact that through the use of digital media, lectures can be organized more flexibly and also the organization of their studies can be optimized. New digital teaching media should be created based on these results. It is important to consider which digital formats seem suitable for which content during different semesters.

ABSTRACT

A previous randomised controlled trial showed that an anti-inflammatory diet (AID) significantly reduced gingival inflammation despite constant plaque values. This exploratory study investigated the role of serum fatty acids in relation to the observed clinical effects. Therefore, data of thirty participants with gingivitis, following either a pro-inflammatory dietary pattern (PID) rich in saturated fat, omega 6 fatty acids, and refined carbohydrates or an AID for 4 weeks, were correlated with corresponding serum samples for a variety of fatty acids. Changes in the fatty acid profile and effects on clinical periodontal parameters were analysed. Results showed that the polyunsatured:saturated fatty acids ratio (PUFA:SFA ratio) and nervonic acid level were significantly higher in the AID group than in the PID group at the end of the study. Significant intragroup differences were seen only in the AID group. Diverse fatty acids showed heterogeneous relations to clinical parameters. This study demonstrated that the serum fatty acid profile was not fundamentally associated with the clinical gingivitis-lowering effects of an AID in short-term, although some fatty acids showed individual relations to clinical parameters with respect to inflammation. Hence, short-term effects of dietary therapy on gingivitis may be rather based on carbohydrate-related effects and/or micronutrients.

ABSTRACT

BACKGROUND: This study investigated clinical parameters using a new air-polishing device compared to sonic scaling for subgingival biofilm removal during supportive periodontal therapy. The aim was to evaluate noninferiority of air-polishing compared to sonic scaling in deeper periodontal pockets with respect to pocket depth (PD). METHODS: In 44 participants, 2 single-rooted teeth [(PD) ≥ 5 mm] were treated using a split-mouth design. While a new air polishing device with a conical shaped tip was used for the experimental group, sonic scaling was performed in the control group. PD, clinical attachment level (CAL), and bleeding on probing (BOP) were recorded at baseline, (T0) after 3 months (T1) and 6 months (T2). Pain perception was rated using a visual analog scale (VAS; 0 = no pain, 100 = maximum pain). RESULTS: PD and CAL decreased significantly for both groups, while no intergroup differences were found (PD [mean, mm] control T0 5.96, T2 4.75; experimental T0 5.96, T2 4.8; intergroup p = 0.998; CAL [mean, mm] control T0 7.38, T2 5.84; experimental T0 7.28, T2 6.34; intergroup p = 0.368). For BOP, no intergroup differences were found from T0 to T2 (reduction control 42.5%; experimental 46.5% p = 0.398). Pain perception was significantly lower for air polishing (VAS [mean, mm] control 28.8, experimental 12.56; p = 0.006). CONCLUSION: None of the two treatment procedures showed inferior clinical effects with regard to PD, CAL and BOP with air polishing being more comfortable to patients. Trial registration The study was registered in an international trial register on August 14/08/2019, before the start of recruitment (German Clinical Trial Register number DRKS00017844).

ABSTRACT

BACKGROUND: This retrospective study investigates the change in the peri-implant bone level (PBL) during the 2nd decade of intraoral function in patients complying with a 'supportive implant therapy' (SIT) program. The results were statistically analyzed with respect to the implant abutment connection used. METHODS: In a private practice, only patients with 20-year SIT compliance were identified. Of these, all patients with 10- and 20-year radiographs available were selected. Therefore, no control group was possible and implant losses had to be excluded. Two experienced researchers assessed the peri-implant bone levels. As three different abutment connection concepts (bone-level butt-joint, bone-level conical and tissue-level conical) and two different implant surfaces (machined vs. roughened) were involved, statistical analyses were performed to detect potential differences. RESULTS: Ninety-three implants from 36 patients with 20-year SIT compliance and available radiographs were included in the study. At study baseline (10 years intraoral), a mean bone loss of - 1.7 mm (median - 1.2; standard deviation [sd] 1.4, range: 0 to - 7.2) was recorded. After 20 years, we found a mean bone loss of - 2.5 mm (median - 2.3, sd 1.79, range: - 0.5 to + 7.4). Furthermore, we found a mean bone loss of 0.8 mm in intraoral function from year 10 to year 20 (mean: 0.08 mm per year); this change was independent of the abutment connection type. CONCLUSIONS: During the 2nd decade of function, peri-implant bone loss in patients with SIT compliance might be small in value and should not be expected in all implants.

ABSTRACT

The aim of this randomized, controlled, double-blinded clinical trial was to examine the additional healing effect of transgingival visible light and water-filtered infrared-A (VIS + wIRA) in the treatment of periodontitis patients compared with the standard therapy by subgingival instrumentation (SI). Therefore, forty patients with untreated periodontitis received a non-surgical periodontal treatment. Using a split-mouth study design, one quadrant of the upper jaw was randomly either exposed to VIS + wIRA four times for 20 min within two weeks in addition to SI or received only SI. Three and 6 months after intervention, clinical parameters (probing depths (PDs), clinical attachment level, bleeding on probing (BOP), furcation, tooth mobility, plaque control record, and papilla bleeding index) were re-evaluated. In the presence of PD of 4 mm and positive BOP or PD > 4 mm, SI was performed again. Moreover, the patients were asked about their discomfort using a visual analog scale from 1 to 10 for each side of the maxilla. Statistical analysis demonstrated no differences between quadrants at re-evaluation for clinical parameters (p > 0.05) after 3 and 6 months. Concerning pain perception, patients described less pain on the irradiated side (p = 0.016). In the treatment of patients with periodontitis, VIS + wIRA did not show an additional effect on the clinical outcome after 3 and 6 months. Patients described less pain on the irradiated quadrant after treatment.

ABSTRACT

The aim of this randomized, controlled clinical trial was to isolate and identify viable microorganisms in the saliva of study participants that continuously used a stannous and fluoride ion (F/Sn)-containing toothpaste and mouth rinse over a period of three years in comparison to a control group that used stannous ion free preparations (noF/Sn) over the same time period. Each group (F/Sn and noF/Sn) included 16 participants that used the respective oral hygiene products over a 36-month period. Stimulated saliva samples were collected at baseline (T0) and after 36 months (T1) from all participants for microbiological examination. The microbial composition of the samples was analyzed using culture technique, matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry, and 16S rDNA Polymerase Chain Reaction (PCR). There were only minor differences between both groups when comparing the absolute values of viable microbiota and bacterial composition. The treatment with F/Sn led to a slight decrease in disease-associated and a slight increase in health-associated bacteria. It was shown that the use of stannous ions had no negative effects on physiological oral microbiota even after prolonged use. In fact, a stabilizing effect of the oral hygiene products containing stannous ions on the health-associated oral microbiota could be expected.

ABSTRACT

INTRODUCTION: Length of hospital stay after birth has decreased during the last decades, but nationwide data on length of hospital stay after cesarean section are lacking. Elements of Enhanced Recovery Programs were reported to reduce the length of hospital stay. The aim of this nationwide study was to describe the length of hospital stay after cesarean section in Denmark from 2004 to 2016 taking into account birth- and health-related factors as well as demographic changes and, further, to assess potential differences between the five Danish regions. MATERIAL AND METHODS: Length of hospital stay was assessed in 164 209 deliveries by cesarean section in Denmark from 2004 to 2016. Data were obtained from the Danish National Patient Register. All deliveries by cesarean section at gestational age <22 weeks were excluded. Median length of hospital stay was reported based on crude and adjusted analyses. RESULTS: The median length of hospital stay was significantly reduced by 39 hours (95% confidence interval [CI] 37.9-40.1), from 97 hours (4.0 days) in 2004 to 58 hours (2.4 days) in 2016. Reductions were observed among both planned and emergency cesarean sections. When birth- and health-related factors as well as demographic changes were accounted for, median length of hospital stay was reduced by 30 hours (95% CI 29.3-30.8) in the period. The decrease in length of hospital stay from 2004 to 2016 varied between the five Danish regions, with adjusted reductions between 19 and 46 hours. CONCLUSIONS: A nationwide decrease in length of hospital stay after cesarean section was observed from 2004 to 2016 across all five regions but with significant regional variations. Further studies on the optimal length of hospital stay are needed, especially with regard to implementation of enhanced recovery programs.

ABSTRACT

INTRODUCTION: In some European countries, discharge the day after planned cesarean section has become an accepted procedure. However, little is known about the patients' perception of early discharge. The aim of this study was to compare early discharge with standard care in relation to parental sense of security. Further, we evaluated postoperative pain, mobilization, and readmission. MATERIAL AND METHODS: We performed a randomized clinical trial including parous, singleton pregnant women with a planned cesarean section at term. The women were allocated to either discharge within 28 hours (intervention group) or after 48 hours (standard care group) following the cesarean section. Women discharged within 28 hours after cesarean section were offered a home visit by a midwife the following day. The primary outcome was the postnatal sense of security, which was reported by the woman and her partner in the "Parents' Postnatal Sense of Security" questionnaire 1 week postpartum. Secondary outcomes were pain score, use of analgesics, mobilization, readmission, and contacts with the healthcare system in the postoperative period. RESULTS: We included 143 women, of whom 72 were allocated to the intervention group and 71 were allocated to the standard care group. There were no differences in baseline characteristics. The two groups did not differ concerning the postnatal sense of security for the women (P = .98) or the postnatal sense of security for the partners (P = .38). We found no difference in pain scores, step count, use of analgesics, or number of contacts with the health-care system between the groups. CONCLUSIONS: Parental postnatal sense of security is not compromised by discharge within 28 hours followed by a home visit compared with discharge after 48 hours after planned cesarean section among parous women.

ABSTRACT

BACKGROUND: Host modulation therapy has gained increasing interest in periodontal therapy. This systematic review aimed to evaluate the effects of adjunctive administration of omega-3 fatty acids in periodontal therapy. METHODS: The search strategy was determined using the "patient, intervention, comparison, outcome" model. A resulting search term was generated using keywords, and the databases were fed. The databases PubMed, Cochrane Library, and LIVIVO were used. Studies were selected for the literature review based on previously specified inclusion and exclusion criteria. Randomized, controlled, blinded studies, longitudinal studies, comparative studies, and clinical studies were included in the review. Additionally, they used omega-3 fatty acids in the treatment of periodontitis. The following parameters were observed: clinical attachment level (CAL), probing depth (PD), gingival index (GI), bleeding on probing (BOP) and plaque index (PI). A meta-analysis was performed for PD and CAL after 3 months. By analyzing the risk of bias, the validity of the results of each study was demonstrated, and its credibility and quality were assessed. RESULTS: Of 14 studies found, six were included. The results showed a significant reduction in PD and CAL compared to that in the placebo groups in four out of six involved studies, which was confirmed by the meta-analysis. In one study, a significant reduction in BOP was found. GI was significantly reduced in three included studies. PI also showed a significant reduction in three studies. CONCLUSIONS: Within the study limitations, omega-3 fatty acids appear to have a positive effect on periodontal wound healing with regard to reduction in CAL and PD. Based on the results, patients receiving periodontal treatment might benefit from nutritional counseling.

ABSTRACT

BACKGROUND: This pilot study was part of a larger study which compared the effect of subgingival air-polishing using trehalose powder with sonic scaling on clinical parameters during supportive periodontal therapy. Within this microbiological part of the investigation subgingival samples were taken from 10 participants to analyze the survival of different bacterial species after the two different treatments as a proof of principle. METHODS: In 10 participants two non-adjacent, single-root teeth requiring treatment (PD =5 mm with bleeding on probing (BOP) or > 5 mm) were selected following a split-mouth design and were treated either with a sonic scaler or air-polishing device and trehalose powder. For persistent pockets (PD =4 mm and BOP or > 4 mm), treatment was repeated after 3 months. Subgingival biofilm samples were taken at baseline (BL), subsequently and three and six months after treatment. After determination of the bacterial counts (TBL), isolated bacteria were identified by MALDI-TOF-MS. If unsuccessful, PCR and 16S rDNA sequencing were performed. RESULTS: In both treatment groups, TBL decreased immediately after treatment remaining at a lower level. This confirms the findings of the larger study regarding clinical parameters showing a comparable effect on PD, BOP and CAL. Immediately after treatment, the diversity of detected species decreased significantly more than in the sonic group (p = 0.03). After 3 months, the proportion of Gram-positive anaerobic rods was lower in the air-polishing group (powder/ sonic 7%/ 25.9%, p = 0.025). Also, there was a greater reduction of Gram-negative aerobic rods for this group at this time (air-polishing/ sonic - 0.91 / -0.23 Log10 cfu/ ml, p = 0.020). CONCLUSION: Within the limitations of this study air-polishing and sonic treatment seem to have a comparable effect on the subgingival oral biofilm during supportive periodontal treatment. TRIAL REGISTRATION: The study was registered in an international trial register (German Clinical Trial Register number DRKS 00006296) on 10th of June 2015. HTML&TRIAL_ID = DRKS00006296.

ABSTRACT

OBJECTIVE: The birth rate in Denmark is increasing, and the rate of births by caesarean section has increased to more than 20%. Thus, the obstetric departments have been put under pressure to identify new solutions to optimize the maternity care system, in which early discharge might be considered. The aim of this study was to explore parents' experiences of the postnatal care after planned caesarean section with focus on factors that support or hinder early discharge. DESIGN: An interpretive, hermeneutic approach was chosen, using qualitative interviews with multiparous women and their partners. Data analysis was performed using thematic analysis. PARTICIPANTS AND SETTING: Twelve women and partners were recruited from two hospital-based maternity units in Denmark. The inclusion criteria were low-risk Danish-speaking multiparous women having a planned caesarean section with a singleton pregnancy (gestational age between 37+0 and 41+6 weeks). Seven sets of parents were discharged before 28 h and five were discharged after 48 h. FINDINGS: Three main themes were identified as important for timing of discharge: (1) Setting for recovery (2) Views on length of stay, and (3) Preparation and individual planning. All parents valued the safe and supportive environment at the hospital, but several preferred early discharge as they felt more comfortable in their home environment and wanted to be together as a family with all siblings. When considering appropriate time of discharge, the main issues were that pain was manageable, that breastfeeding was initiated successfully and that professional support was available after discharge. Finally, early discharge required preparation and planning and the parents stressed the importance of knowing that they would not be discharged unless they felt ready. CONCLUSION AND IMPLICATION FOR PRACTICE: A clear link was observed between the care package the parents received and their views on the optimal time of discharge. Based on our findings it seems likely that a significant proportion of parents will accept and feel confident about early discharge if individual circumstances are taken into account in the antenatal planning of a caesarean section.

ABSTRACT

INTRODUCTION: The importance of good communication in dentistry is proven in terms of both medical satisfaction and patient-related recovery and prevention. The present work deals with the comparison of communicative abilities and the communicative self-assessment of licensed dentists as well as students of dentistry with special emphasis on the influence of the treatment experience. MATERIALS AND METHODS: A total of 34 dentists (experimental group) with an average work experience of 16 years and 36 students (control group) with an average of 1.4 years of treatment experience were included. In addition to a tutor, four types of simulation patients with standardised trained roles (anxious, critical, dissatisfied and difficult to motivate) were used to create reproducible conversations. The self-assessment and evaluation of the conversation took place by completing questionnaires. Here, an introductory questionnaire was distributed to the participants prior to the conversation and another one after intervention. Whilst the tutors completed their survey during the intervention, the simulation patients answered their questions after the conversation. RESULTS: The results showed that the dentists rated their own communication skills significantly higher than the students for anxious (P < 0.001) and unmotivated patients (P = 0.026). However, the evaluation of the simulated patients showed that the students achieved higher overall empathy scores (42.03 vs 38.77, P = 0.016). CONCLUSION: Due to the declining empathy values with increasing treatment experience, communication training is useful for the daily routine of treatment even for experienced dentists.

ABSTRACT

INTRODUCTION: The objective of the study was to investigate whether outpatient total laparoscopic hysterectomy (TLH) could be performed as a routine without compromising patient satisfaction. The main outcomes were patient satisfaction with length of hospital stay, quality of life, complications and readmissions, and time to return to work. MATERIAL AND METHODS: A non-blinded prospective randomized controlled trial (Canadian Task Force classification I) performed in a single-center teaching hospital in Denmark. A total of 204 women scheduled for TLH on benign indication were randomized to same-day discharge or overnight stay after TLH. Visual analogue scales (VAS), a validated questionnaire EQ-5D, and a diary were filled in pre- and postoperatively. VAS scores on satisfaction with length of hospital stay and pain were administered taken with the EQ-5D and the diary during a follow up over 4 weeks. Student's t test, Chi-square and non-parametric statistics were used for analysis. The study was registered with ClinicalTrials.gov #NCT02933047. RESULTS: A total of 204 women gave informed consent and 203 underwent surgery (101 outpatient and 102 inpatient women). Complete data were available for 76 women in the outpatient group and 86 women in the inpatient group. There were no differences in baseline characteristics. No group differences were found in satisfaction with length of hospital stay (P = 0.35). The EQ-5D revealed no difference in patient satisfaction. However, one-third in the outpatient group chose overnight stay without medical indication. The groups were comparable in clinical outcomes. Sick leave was longer in the outpatient group regardless of the actual treatment (P = 0.015). CONCLUSIONS: Routine outpatient TLH implies that one-third of the patients stay overnight if this option is available without medical indication. Within this context the procedure can be performed with high patient satisfaction, but may lengthen the time to return to work.

ABSTRACT

BACKGROUND: Air-polishing appears to be a promising procedure for subgingival biofilm removal in periodontal treatment. The aim of this study was to compare trehalose powder for subgingival air-polishing with sonic debridement in residual periodontal pockets during maintenance therapy. METHODS: In this blinded, randomized, controlled clinical trial conducted over 6 months with a split-mouth design, single-rooted teeth in 44 participants with residual pocket depths of 5 mm and bleeding or >5 mm with and without bleeding were included in this study. Subgingival debridement was carried out using either trehalose powder with an air-polishing device (test) or a sonic device (control). The reduction in the probing depths after 3 and 6 months was defined as the primary endpoint. A visual analog scale was used to evaluate the discomfort of both procedures. RESULTS: Both procedures showed statistically significant intragroup reductions in probing depths (test baseline [BL] 5.52 ± 0.93, 6 months 3.66 ± 0.81, control BL 5.55 ± 0.9, 6 months 3.68 ± 0.86, P < 0.001), clinical attachment level (test BL 6.93 ± 1.5, 6 months 5.3 ± 1.52, control BL 7.27 ± 1.8, 6 months 5.84 ± 1.71, P < 0.001), and bleeding on probing (test BL 86%, 6 months 41%, control BL 89%, 6 months 34%, P < 0.001) after 6 months with no significant intergroup differences (P > 0.05, respectively). The visual analog scale showed a significantly lower incidence of discomfort for air-polishing compared with sonic scaling (test 2.33 ± 2.14, control 4.91 ± 2.65, P < 0.001). CONCLUSIONS: Subgingival air-polishing with trehalose powder showed comparable clinical outcomes to sonic scaling. Sonic scaling evoked more discomfort compared with air-polishing.

ABSTRACT

BACKGROUND: Lawsonia intracellularis is one of the most economically important pathogens in swine production. This study tested the hypothesis that the composition of diets for pigs has an impact on the excretion of L. intracellularis in a natural infection model. RESULTS: Fifty boars (~ 90 kg BW) from a SPF-farm with a strict hygiene and management regime for reducing the spread of an L. intracellularis infection up to the beginning of the final fattening period were transported, regrouped and randomly allotted to groups of five animals each at the research facility. After a 1-week acclimatisation period groups were fed one of five diets 4 weeks before slaughter. These were either a finely ground pelleted diet (FP) or a coarsely ground meal diet (CM), both consisting of wheat (40.0%), barley (39.3%), soybean meal (16.0%), soybean oil (2.0%) and minor components. In the other meal diets parts of wheat, barley and soybean meal were substituted either with 22% cracked corn (CORN), 16.9% dried whey (WHEY) or 30% raw potato starch (RPS). The animals had a comparable serological status in a blocking-ELISA immediately before the start and at the end of the feeding experiment. Values increased significantly during the trial. In all subgroups (FP/CM/CORN/WHEY/RPS), shedding was detected in week 0 (genome equivalents = GE; log10 GE L. intracellularis/g faeces: 2.46 ± 2.64/3.58 ± 2.54/3.43 ± 2.37/2.30 ± 3.16/2.58 ± 2.73). The average number of L. intracellularis microbes in faeces during the trial period did not differ between the groups (log10 GE L. intracellularis/g faeces: 3.40 ± 1.53/3.01 ± 1.41/3.80 ± 1.71/3.98 ± 2.20/4.08 ± 2.13). In animals fed the WHEY-diet, significantly lower counts of L. intracellularis were found in the caecal content. The acetate content in the caecum was negatively correlated with the serological results at the end of the trial (r = - 0.36; P = 0.010). Butyrate concentrations in the caecal content were negatively correlated with the number of L. intracellularis in the caecum (r = - 0.32; P = 0.023). CONCLUSION: Therefore, this study provides preliminary evidence that there might be specific dietary effects on the course of a L. intracellularis infection.

ABSTRACT

OBJECTIVES: The objective of this study was to investigate clinical and microbiological gingival changes during pregnancy in women without periodontal disease. Additionally, these parameters were to be compared in women with high risk for preterm birth and women with a normal course of pregnancy. METHOD AND MATERIALS: Group I consisted of 40 subjects at high risk for preterm birth, while group II involved 49 subjects with a normal course of pregnancy. The control group (III) was made up of 50 non-pregnant women. Clinical parameters (plaque index, gingival index, probing pocket depths, gingival swelling, bleeding on probing) and microbiological changes were monitored during pregnancy and 2-4 weeks after parturition. RESULTS: In the high-risk preterm group (I), 19 women could be included in data analysis. This group was compared to 41 women in the normal pregnancy group (II) and 50 non-pregnant women (III). Gingival inflammation was significantly higher in women with high risk for preterm birth (I) compared to non-risk pregnant women (II, p < 0.05). In addition, in this group (I), the subgingival amounts of Fusobacterium nucleatum (> 105) were found to be significantly higher after childbirth compared to non-pregnant women (p < 0.05). CONCLUSIONS: Even without having periodontal disease, women with high risk for preterm birth showed worse clinical values compared to non-risk pregnant and non-pregnant women and an increased detection of Fusobacterium nucleatum after delivery. CLINICAL RELEVANCE: High risk for preterm birth might be associated with the occurrence of increased gingival inflammation.

ABSTRACT

PURPOSE: Information about the perioperative incontinence following hysterectomy is limited. To advance the postoperative rehabilitation further we need more information about qualitative changes in incontinence, fatigue and physical function of patients undergoing hysterectomy. METHODS: 108 patients undergoing planned hysterectomy were compared pre- and postoperatively. In a sub-study of the prospective follow-up study the changes in incontinence, postoperative fatigue, quality of life, physical function, and body composition were evaluated preoperatively, 13 and 30 days postoperatively. Sample size calculation indicated that 102 women had to be included. The incontinence status was estimated by a Danish version of the ICIG questionnaire; further, visual analogue scale, dynamometer for hand grip, knee extension strength and balance were applied. Work capacity was measured ergometer cycle together with lean body mass by impedance. Quality of life was assessed using the SF-36 questionnaire. Patients were examined preoperatively and twice postoperatively. RESULTS: In total 41 women improved their incontinence after hysterectomy and 10 women reported deterioration. Preoperative stress incontinence correlated with BMI (r = 0.25, p < 0.01) and urge incontinence with age (r = 0.24, p < 0.02). Further, improvement after hysterectomy in stress incontinence was associated with younger age (r = 0.20, p < 0.04). Improvement in urge incontinence was positively associated with BMI (r = 0.22, p = 0.02). A slight but significant loss was seen in lean body mass 13 and 30 days postoperatively. CONCLUSIONS: Hysterectomy was not significantly associated with the risk of incontinence; in particular, when no further vaginal surgery is performed. Hysterectomy may even have a slightly positive effect on incontinence and de-novo cure.
