Abstract
Summary Background. The human microbiome is important due to the impact it has on host immunologic development and allergy-associated diseases. This study aimed to investigate the impact of prenatal exposure to antibiotics on the incidence of atopic dermatitis (AD) in children at 18 months of age. Methods. Mothers were interviewed at baseline, in the maternity ward and by phone questionnaire after 18 months. Demographic data, mode of delivery, yoghurt consumption, antibiotic and other drug use during pregnancy, atopic history, diagnosis of AD and history of infections in the offspring were noted. Results. 385 mothers were interviewed at baseline. 231 (60%) mothers with 236 children responded at follow up. Cesarean section was reported in 116 (50.2%) deliveries while antibiotic use during pregnancy in 55/231 (23.8%) women. 43/236 (18.22%) infants were diagnosed with AD. Intravenous antibiotic use was associated with a 7.7 increased risk of AD diagnosis in the offspring (95%CI 1.23-48.27, p = 0.029). An increased odd for AD was recorded for mothers 30-40 years of age (OR 4.50, 95%CI 1.08-18.7, p = 0.039). No significant association between cesarean section and AD (p = 0.70) was recorded. In multivariate analysis, reported food allergy (OR 8.03, 95%CI 2.30-27.97, p = 0.001) and otitis media episodes in children (OR 3.76, 95%CI 1.60-8.83, p = 0.002) were significantly associated with AD diagnosis. Conclusions. An increased risk of AD was recorded only when antibiotics were given prenatally by intravenous route and in women between 30-40 years of age. Children with food allergy had an increased risk for AD. The relatively high percentage of cesarean sections was not a risk factor for AD.

Abstract
BACKGROUND Cooled radiofrequency ablation (CRFA) and cryoneurolysis (CRYO) are two novel methods of genicular neurolysis to relief pain in symptomatic knee osteoarthritis (KOA). In this study, the two methods will be compared, giving us the opportunity to investigate their efficacy, safety and complications. METHODS In this prospective randomized trial 70 patients with KOA will be recruited using a diagnostic block of four genicular nerves. Two groups will be created through software randomization: a CRFA group (35 patients) and a CRYO group (35 patients). The target of the interventions will be four genicular nerves; the superior medial, superior lateral, inferior medial, as well as the medial (retinacular) genicular branch from vastus intermedius. The primary outcome of this clinical trial will be the efficacy of CRFA or CRYO at 2-, 4-, 12-and 24-weeks post-intervention using the Numerical Rating Pain Scale (NRPS). The secondary outcomes are the safety of the two techniques, as well as the clinical evaluation using the Knee Injury and Osteoarthritis Outcome Score (KOOS), the Oxford Knee Score (OKS), and the 7-point scale of Patient Global Impression of Change (PGIC). DISCUSSION These two novel techniques can block pain transmission through genicular nerves in different ways. In contrast to cryoneurolysis, the CRFA method has been well documented in the past. This is the first clinical trial to compare CRFA vs CRYO and draw conclusions about their safety and efficacy. TRIAL REGISTRATION ISRCTN87455770 [ https://doi.org/10.1186/ISRCTN87455770 ].

Abstract
BACKGROUND Despite recent advances in implants and surgical techniques, catastrophic and clinical failures in the treatment of intertrochanteric fractures continue to occur, with dire consequences in an overall frail population subset. The aim of the current study is to evaluate the effect of the factors under the surgeons' control, namely fracture reduction and implant selection, on the biomechanical behavior of fracture fixation constructs. MATERIAL-METHODS An experimental protocol was conducted with the use of instrumented sawbones, in order to validate the finite element models. The implants used were the Gamma3®and DHS systems. Subsequently, a series of scenaria were considered, including various reduction and implant angle combinations. Data were retrieved concerning the peak cancellous bone stresses around the hip screw and the volume of cancellous bone in the femoral head stressed at critical levels, as well as implant stresses and stresses on the cortical bone of the distal fragment. RESULTS All stable fracture models displayed significantly decreased cancellous bone stresses and implant stresses compared to their unstable counterparts, regardless of implant used. The effect of increasing implant angle led to a decrease in implant stresses in all models studied, but had a beneficial effect on the stresses in the cancellous bone of the proximal fragment only in the subgroups of stable fractures with both implants and unstable fractures treated with a cephalomedullary nail (CMN). In unstable fractures anatomically reduced, the use of CMN led to significantly lower peak stresses in the cancellous bone and a smaller volume of bone stressed at critical levels. Increasing the reduction angle by 5 ° led to a significant decrease in both peak stresses and volume of bone stressed at critical levels, more prominent in the sliding hip screw (SHS) models. Decreasing the reduction angle into varus by 5 or 10 ° led to a significant increase in bone and implant stresses regardless of implant used. CONCLUSIONS In stable two-part (AO31.A2) fractures the use of the SHS appears to be biomechanically equivalent to CMN. In unstable, anatomically reduced fractures, the use of CMN leads to significantly reduced cancellous bone stresses and decreased rotation of the proximal fragment during loading. A reduction in varus should be avoided at all costs. In unstable fractures treated with SHS a reduction in slight valgus appears to be biomechanically beneficial. The highest implant angle that allows for proper screw position and trajectory in the femoral head should be used for stable fractures with both implants and unstable fractures treated with Gamma3®.

Abstract
Background: The role of the nasal epithelium in the induction of a proper cytokine response in normal subjects and subjects with allergic rhinitis is still not completely elucidated. Methodology: We aimed to compare nasal epithelial immune responses in allergic rhinitis patients of different ages compared to healthy volunteers. Primary nasal epithelial cells from 47 subjects (33 normal and 17 with allergic rhinitis) were collected and cultured. Their unstimulated supernatants were analysed for 21 cytokines and chemokines. Statistical analysis was performed with the R statistical software and the RStudio interface. Results: Differences of the spontaneous release of epithelial cytokines and chemokines were noticed between the two study groups. The levels of GMCSF, MIP1A, MIP1B, IL28A, TNFA, CCL5 were significantly lower in the allergic rhinitis group compared to healthy volunteers’ group, independent of age. Most differences were noticed in the younger allergic rhinitis group (0-12 years old). Conclusions: Despite the cross-sectional nature of the study and the limited number of subjects, allergic rhinitis appears to be associated with dysfunction of cytokine and chemokine spontaneous release from nasal epithelial cells which may represent an abnormal innate immunity maturation pattern.

Abstract
Background There is great design variability on short femoral stems available on the market. This study aims to evaluate the short-term clinical and radiological results of two different design short femoral stems, both classified as shortened tapered stems. Methods From March 2016 to March 2018, a prospective, randomized, parallel-group design study was conducted to compare functional and radiological outcomes of 45 patients underwent THA using the Tri-Lock Bone Preservation Stem and 45 patients underwent THA with the Minima S stem at a minimum 2 years of follow-up. Patients were assessed clinically and radiographically prior to surgery as well as at 3, 6, 12, and 24 months postoperatively. Primary outcomes were the change in health-related quality of life assessed with Western Ontario and McMaster Universities Osteoarthritis Index and 36-Item Short Form Health Survey and also the incidence of all hip-related complications. Secondary aims included hip function evaluated with the Harris hip score, rates of patient satisfaction, and the outcomes of a detailed radiological analysis. Results There were no significant differences between the 2 study groups in terms of patient-reported outcomes measurements, satisfaction scores, and complication rates at any of the measurement times. In both groups, stable fixation and radiographic osseointegration were achieved. However, analysis of the calcar region showed that 57.8% and 28.9% of patients had grade 1 or 2 stress shielding, in Tri-Lock and Minima S implantation group, respectively (p=0.015). Regarding coronal alignment, stems were placed in slight varus, valgus, and neutral position in 51.1%, 13.3%, and 35.6% of patients, respectively, in Tri-Lock BPS group. The Minima S stem was implanted at slight varus and valgus in 60% and 40% of patients, respectively, and neither stem in the exact neutral position. Conclusions Both different design short femoral stems demonstrated excellent clinical performance at short-term follow up. Nevertheless, concerns were raised regarding the incidence of stress shielding phenomenon and mild discrepancies in coronal stem alignment during implantation. The clinical impact of these observations should be further evaluated through larger cohorts and longer follow-up. Trial registration ISRCTN registry, ISRCTN10096716.

Abstract
BACKGROUND The role of Helicobacter pylori infection and especially of the cytotoxin-associated gene A (CagA) product strain in peptic ulcer bleeding among non-steroidal anti-inflammatory drugs (NSAIDs) users remains controversial. METHODS A case-control study was carried out including 191 consecutive chronic NSAIDs users admitted to hospital because of peptic ulcer bleeding. Peptic ulcer was verified by endoscopy. Controls comprised 196 chronic NSAIDs users without signs of bleeding of similar age and gender to cases. Multivariate regression analysis was performed for further evaluation of the relationship between H. pylori, CagA status and other risk factors. RESULTS H. pylori infection was present in 121 (63.4%) cases compared with 119 (60.7%) controls (odds ratio (OR) = 1.14, 95% CI, 0.76-1.72). CagA-positive strains were found to be significantly more frequent in cases than in controls (65/106 versus 41/99 P = 0.008). Current smoking (OR = 2.65; 95% CI, 1.14-6.15; P= 0.02), CagA status (OR = 2.28; 95% CI, 1.24-4.19; P = 0.008), dyspepsia (OR = 6.89; 95% CI, 1.84-25.76; P = 0.004) and past history of peptic ulcer disease (OR=3.15; 95% CI, 1.43-6.92; P=0.004) were associated significantly with increased risk of bleeding peptic ulcer. CONCLUSIONS The results suggest that CagA-positive H. pylori infection is associated with a more than 2-fold increased risk of bleeding peptic ulcer among chronic NSAIDs users.
