Ammoniakemissie en emissiereductie van het balansballensysteem bij vleesvarkens
This research was conducted to measure the effect of the “balansballen” system, with and without VevoVitall®, on the ammonia emission from growing-finishing pigs housed in partly slatted pens that were fully equipped with a manure pit underneath. These emissions were compared to a reference system (without VevoVitall® and without the “balansballen” system) in order to determine the emission reduction of both treatments. The measurements were performed according to the measurement protocol “Ammonia emission from animal houses 2007”
Prospective comparative study between colposcopy and histopathology for diagnosis of CIN and carcinoma cervix
Background: Cervical cancer develops from precursor lesions and detection of these lesions is of utmost importance. The detection of precancerous lesions is made with help of screening tests most important include PAP smear and colposcopy. So we conducted this study to understand the role of colposcopy in down staging of Carcinoma cervix.Methods: We performed a prospective study between Jan 2018 to Dec 2018 on 180 subjects chosen from patients who sought consultation for various gynaecological complaints between age group of 18-60 years. A Pap smear followed by a colposcopy was performed and colposcopic directed biopsies were taken and subjected to histolopathological examination.Results: Colposcopy had a sensitivity of 83.3%, specificity of 78.5%, PPV of 68.9% for CIN 1. It had a sensitivity of 90.9%, specificity of 95.2%, PPV of 83.33% for CIN 2 and 3 when co related with gold standard histopathology which is much higher as compared to Pap smear.Conclusions: Colposcopy is an effective tool in down staging of Carcinoma cervix
A prospective study to compare levonogestrol intrauterine system and trans-cervical resection of endometrium for treatment of abnormal uterine bleeding
Background: This article is a study comparing the two most accepted forms of treatment for abnormal uterine bleeding - levonorgestrol intrauterine treatment and transcervical resection of endometrium, with regards to its acceptability, efficacy, adverse effects and user satisfaction. Aim of this study was to compare the acceptability, efficacy, adverse effects and user satisfaction of LNG-IUS and TCRE for treatment for AUB.Methods: A prospective observational study conducted in SKNMC and GH. Forty-nine women with abnormal uterine bleeding after hysteroscopic evaluation were included in this study; where 17 opted for LNG-IUS; 32 opted for TCRE with bipolar electrode. 15 patients in LNG-IUS group and 28 pts in TCRE group completed follow up. Menstrual pattern, pictorial blood loss assessment chart score, adverse effects, acceptability, satisfaction and reason for discontinuation were recorded at 6 weeks, 6 months and 12 months after the procedure. Prior to LNG-IUS insertion or endometrial ablation, endometrial and cervical pathology were excluded by D and C and cervical smear, respectively. TVUS was used to exclude possible causes of menorrhagia, including myomas and endometrial polyp as well as adnexal pathology. LNG-IUS insertion was performed as an office procedure one day after cessation of menstrual bleeding with a negative urine pregnancy test.Results: Menstrual blood loss reductions in TCRE and LNG-IUS groups were by 85.7% and 87.6% respectively after a year. Amenorrhoea was more common in TCRE group while spotting and systemic effects were more common in LNG-IUS group. Satisfaction and acceptance rates are higher in TCRE group.Conclusions: The TCRE and LNG-IUS are equally effective in reducing bleeding in AUB patients. Acceptance and satisfaction are better with TCRE, as a modality of treatment for AUB
Modafinil reduces patient-reported tiredness after sedation/analgesia but does not improve patient psychomotor skills
Background: Early recovery of patients following sedation/analgesia and anesthesia is important in ambulatory practice. The aim of this study was to assess whether modafinil, used for the treatment of narcolepsy, improves recovery following sedation/analgesia. Methods: Patients scheduled for extracorporeal shock wave lithotripsy were randomly assigned to one of four groups. Two groups received a combination of fentanyl/midazolam with either modafinil or placebo. The remaining groups received remifentanil/propofol with either modafinil or placebo. Modafinil 200 mg was administered to the treatment group patients 1 h before sedation/analgesia. Groups were compared using the digital symbol substitution test (DSST), trail making test (TMT), observer scale of sedation and analgesia (OAA/S) and Aldrete score. Verbal rating scale (VRS) scores for secondary outcome variables e.g. energy, tiredness and dizziness were also recorded before and after treatment. Results: Sixty-seven patients successfully completed the study. Groups received similar doses of sedation and analgesic drugs. No statistically significant difference was found for DSST between groups. No significant adverse effects occurred in relation to modafinil. No statistically significant difference between groups was identified for TMT, OAA/S and Aldrete scores. The mean VRS score for tiredness was lesser in the modafinil/fentanyl/midazolam group [1.3 (2.0)] compared with the placebo group [3.8 (2.5)], P=0.02. Such a difference was not found between the remifentanil/propofol groups [placebo 2.6 (2.2) vs. modafinil 3.1(2.7)], p>0.05. Dizziness was greater in the modafinil/remifentanil/propofol group 1.7 (2.0) vs. placebo 0.0 (0.5), p<0.05. Conclusion: Modafinil reduces patient-reported tiredness after sedation/analgesia but does not improve recovery in terms of objective measures of patient psychomotor skills.</p

Investigating Real-World Benefits of High-Frequency Gain in Bone-Anchored Users with Ecological Momentary Assessment and Real-Time Data Logging
Purpose: To compare listening ability (speech reception thresholds) and real-life listening experience in users with a percutaneous bone conduction device (BCD) with two listening programs differing only in high-frequency gain. In situ real-life experiences were recorded with ecological momentary assessment (EMA) techniques combined with real-time acoustical data logging and standard retrospective questionnaires. Methods: Nineteen experienced BCD users participated in this study. They all used a Ponto 4 BCD from Oticon Medical during a 4-week trial period. Environmental data and device parameters (i.e., device usage and volume control) were logged in real-time on an iPhone via a custom iOS research app. At the end of the trial period, subjects filled in APHAB, SSQ, and preference questionnaires. Listening abilities with the two programs were evaluated with speech reception threshold tests. Results: The APHAB and SSQ questionnaires did not reveal any differences between the two listening programs. The EMAs revealed group-level effects, indicating that in speech and noisy listening environments, subjects preferred the default listening program, and found the program with additional high-frequency gain too loud. This finding was corroborated by the volume log—subjects avoided the higher volume control setting and reacted more to changes in environmental sound pressure levels when using the high-frequency gain program. Finally, day-to-day changes in EMAs revealed acclimatization effects in the listening experience for ratings of “sound quality” and “program suitability” of the BCD, but not for ratings of “loudness perception” and “speech understanding”. The acclimatization effect did not differ among the listening programs. Conclusion: Adding custom high-frequency amplification to the BCD target-gain prescription improves speech reception in laboratory tests under quiet conditions, but results in poorer real-life listening experiences due to loudness
Hearing Rehabilitation of Patients with Chronic Otitis Media:A Discussion of Current State of Knowledge and Research Priorities
Although chronic otitis media is a major cause of conductive and mixed hearing loss, auditory rehabilitation is currently not optimal for this patient group. Planning for hearing rehabilitation must accompany strategies for infection control when surgically managing patients with chronic otitis media. Several barriers prevent adequate hearing restoration in such a heterogeneous patient population. A lack of standardized reporting of surgical interventions, hearing, and quality of life outcomes impedes meta-analyses of existing data and the generation of high-quality evidence, including cost-effectiveness data, through prospective studies. This, in turn, prevents the ability of clinicians to stratify patients based on prognostic indicators, which could guide the decision-making pathway. Strategies to improve reporting standards and methods have the potential to classify patients with chronic otitis media preoperatively, which could guide decision-making for hearing restoration with ossiculoplasty versus prosthetic hearing devices. Appropriately selected clinical guidelines would not only foster directed research but could enhance patient-centered and evidence-based decision-making regarding hearing rehabilitation in the surgical planning process
