Association between upper and lower respiratory disease among patients with primary ciliary dyskinesia: an international study

Introduction

Nearly all patients with primary ciliary dyskinesia (PCD) report ear-nose-throat (ENT) symptoms. However, scarce evidence exists about how ENT symptoms relate to pulmonary disease in PCD. We explored possible associations between upper and lower respiratory disease among patients with PCD in a multicentre study.

Methods

We included patients from the ENT Prospective International Cohort (EPIC-PCD). We studied associations of several reported ENT symptoms and chronic rhinosinusitis (defined using patient-reported information and examination findings) with reported sputum production and shortness of breath, using ordinal logistic regression. In a subgroup with available lung function results, we used linear regression to study associations of chronic rhinosinusitis and forced expiratory volume in 1 s (FEV1) accounting for relevant factors.

Results

We included 457 patients (median age 15 years, interquartile range 10-24 years; 54% males). Shortness of breath associated with reported nasal symptoms and ear pain of any frequency, often or daily hearing problems, headache when bending down (OR 2.1, 95% CI 1.29-3.54) and chronic rhinosinusitis (OR 2.3, 95% CI 1.57-3.38) regardless of polyp presence. Sputum production associated with daily reported nasal (OR 2.2, 95% CI 1.20-4.09) and hearing (OR 2.0, 95% CI 1.10-3.64) problems and chronic rhinosinusitis (OR 2.1, 95% CI 1.48-3.07). We did not find any association between chronic rhinosinusitis and FEV1.

Conclusion

Reported upper airway symptoms and signs of chronic rhinosinusitis associated with reported pulmonary symptoms, but not with lung function. Our results emphasise the assessment and management of upper and lower respiratory disease as a common, interdependent entity among patients with PCD.

Cystic Fibrosis Cases Missed by Newborn Bloodspot Screening-Towards a Consistent Definition and Data Acquisition

Repeated European surveys of newborn bloodspot screening (NBS) have shown varied strategies for collecting missed cases, and information on data collection differs among countries/regions, hampering data comparison. The ECFS Neonatal Screening Working Group defined missed cases by NBS as either false negatives, protocol-related, concerning analytical issues, or non-protocol-related, concerning pre- and post-analytical issues. A questionnaire has been designed and sent to all key workers identified in each NBS programme to assess the feasibility of collecting data on missed cases, the stage of the NBS programme when the system failed, and individual patient data on each missed case.

Sinonasal disease among patients with primary ciliary dyskinesia: an international study

Background

Sinonasal symptoms are a common feature of primary ciliary dyskinesia (PCD); however, literature about their severity and frequency, particularly during the life course, is scarce. Using baseline data from the Ear, nose and throat (ENT) Prospective International Cohort of PCD patients, we describe sinonasal disease in PCD.

Methods

We included participants who had a routine sinonasal examination during which they completed a symptoms questionnaire. We compared frequency of reported symptoms and examination findings among children and adults, and identified characteristics potentially associated with higher risk of sinonasal disease using ordinal regression.

Results

12 centres contributed 384 participants; median age was 16 years (IQR 9-22), and 54% were male. Chronic nasal problems were the most common feature, reported by 341 (89%). More adults (33; 24%) than children (10; 4%) described hyposmia. Quality of life was moderately affected by rhinosinusitis among 136 participants with completed SNOT-22 questionnaires (median score 31; IQR 23-45). Examinations revealed nasal polyps among 51 of 345 participants (15%) and hypertrophic inferior nasal turbinates among 127 of 341 participants (37%). Facial pain was detected in 50 of 342 participants (15%). Nasal polyps, hypertrophic turbinates, deviated septum and facial pain were found more commonly in adults than children. The only characteristic associated with higher risk of sinonasal disease was age 10 years and older.

Conclusions

Based on our findings, regular sinonasal examinations are relevant for patients with PCD of all ages. There is a need for improved management of sinonasal disease supported by evidence-based guidelines.

Diffuse alveolar haemorrhage in children: an international multicentre study

Background

Paediatric diffuse alveolar haemorrhage (DAH) is a rare heterogeneous condition with limited knowledge on clinical presentation, treatment and outcome.

Methods

A retrospective, descriptive multicentre follow-up study initiated from the European network for translational research in children's and adult interstitial lung disease (Cost Action CA16125) and chILD-EU CRC (the European Research Collaboration for Children's Interstitial Lung Disease). Inclusion criteria were DAH of any cause diagnosed before the age of 18 years.

Results

Data of 124 patients from 26 centres (15 counties) were submitted, of whom 117 patients fulfilled the inclusion criteria. Diagnoses were idiopathic pulmonary haemosiderosis (n=35), DAH associated with autoimmune features (n=20), systemic and collagen disorders (n=18), immuno-allergic conditions (n=10), other childhood interstitial lung diseases (chILD) (n=5), autoinflammatory diseases (n=3), DAH secondary to other conditions (n=21) and nonspecified DAH (n=5). Median (IQR) age at onset was 5 (2.0-12.9) years. Most frequent clinical presentations were anaemia (87%), haemoptysis (42%), dyspnoea (35%) and cough (32%). Respiratory symptoms were absent in 23%. The most frequent medical treatment was systemic corticosteroids (93%), hydroxychloroquine (35%) and azathioprine (27%). Overall mortality was 13%. Long-term data demonstrated persistent abnormal radiology and a limited improvement in lung function.

Conclusions

Paediatric DAH is highly heterogeneous regarding underlying causes and clinical presentation. The high mortality rate and number of patients with ongoing treatment years after onset of disease underline that DAH is a severe and often chronic condition. This large international study paves the way for further prospective clinical trials that will in the long term allow evidence-based treatment and follow-up recommendations to be determined.

Clinical and Functional Characteristics of the E92K CFTR Gene Variant in the Russian and Turkish Population of People with Cystic Fibrosis

The pathogenic variant E92K (c.274G > A) of the CFTR gene is rare in America and Europe, but it is common for people with cystic fibrosis from Russia and Turkey. We studied the effect of the E92K genetic variant on the CFTR function. The function of the CFTR channel was studied using the intestinal current measurements (ICM) method. The effects of CFTR modulators on the restoration of the CFTR function were studied in the model of intestinal organoids. To assess the effect of E92K on pre-mRNA splicing, the RT-PCR products obtained from patients’ intestinal organoid cultures were analyzed. Patients with the genetic variant E92K are characterized by an older age of diagnosis compared to homozygotes F508del and a high frequency of pancreatic sufficiency. The results of the sweat test and the ICM method showed partial preservation of the function of the CFTR channel. Functional analysis of CFTR gene expression revealed a weak effect of the E92K variant on mRNA-CFTR splicing. Lumacaftor (VX-809) has been shown to restore CFTR function in an intestinal organoid model, which allows us to consider the E92K variant as a promising target for therapy with CFTR correctors.

Development of Core Outcome Measures sets for paediatric and adult Severe Asthma (COMSA)

BACKGROUND

Effectiveness studies with biological therapies for asthma lack standardised outcome measures. The COMSA (Core Outcome Measures sets for paediatric and adult Severe Asthma) working group sought to develop Core Outcome Measures (COM) sets to facilitate better synthesis of data and appraisal of biologics in paediatric and adult asthma clinical studies.

METHODS

COMSA utilised a multi-stakeholder consensus process among patients with severe asthma, adult, and paediatric clinicians, pharmaceutical representatives and health regulators from across Europe. Evidence included a systematic review of development, validity, and reliability of selected outcome measures plus a narrative review and a pan-European survey to better understand patients' and carers' views about outcome measures. It was discussed using a modified GRADE Evidence to Decision framework. Anonymous voting was conducted using predefined consensus criteria.

RESULTS

Both adult and paediatric COM sets include forced expiratory volume in 1 s (FEV₁) as z scores, annual frequency of severe exacerbations and maintenance oral corticosteroid use. Additionally, the paediatric COM set includes the Paediatric Asthma Quality of Life Questionnaire, and Asthma Control Test (ACT) or Childhood-ACT while the adult COM includes the Severe Asthma Questionnaire and the Asthma Control Questionnaire-6 (symptoms and rescue medication use reported separately).

CONCLUSIONS

This patient-centred collaboration has produced two COM sets for paediatric and adult severe asthma. It is expected that they will inform the methodology of future clinical trials, enhance comparability of efficacy and effectiveness of biological therapies, and help assess their socioeconomic value. COMSA will inform definitions of non-response and response to biological therapy for severe asthma.

The impact of adrenoceptor-1 gene polymorphism on structural and functional features in patients with hypertrophic cardiomyopathy

Background

The adrenergic system plays a central role during the clinical course of hypertrophic cardiomyopathy (HCM) and hence beta-blocker therapy is the first-line treatment option according to current guidelines. Previous studies demonstrated variable cellular response to an adrenergic stimulus due to adrenoceptor-1 (ADRB-1) gene polymorphism in several patient groups including hypertension and dilated cardiomyopathy. Moreover, the impact of beta-blockers is also variable in these patients.

Purpose

We aimed to investigate the impact of ADRB-1 gene polymorphism on structural and functional features among patients with HCM.

Methods

In this study, we investigated the roles of Arginin389Glycine and Glycine49Serine polymorphism. Patients with a clear diagnosis of HCM according to current guidelines were included. Structural features including maximal wall thickness, interstitial fibrosis and left ventricular/atrial volumes were obtained using cardiac MRI and transthoracic echocardiography. Functional features including heart rate, blood pressure, left ventricular outflow obstruction were also recorded. The risk of sudden cardiac death was calculated using the HCM risk score. The impact of beta-blocker therapy on heart rate and blood pressure were also compared.

Results

After the exclusion of patients, 147 patients were included in the study. 77% of the study population were male and the mean age was 49.5 years. The hypertrophic segment was septum in 83% of the study population. The mean maximum wall thickness was 20 mm (19–23). With respect to Ser49Gly polymorphism, Serine homozygotes demonstrated higher late-gadolinium enhancement and indicator of interstitial fibrosis (p: 0.007). In concordance with higher LGE, the presence of fragmented QRS on surface ECG (p: 0.026) and a higher prevalence of non-sustained ventricular tachycardia (p: 0.016) in these patients were observed. The risk of sudden cardiac death was also higher in Ser49 homozygotes (p: 0.041). However, with respect to Arg389Gly gene polymorphism, there was no significant difference between Arg389 homozygotes, Arg389Gly heterozygotes and Gly389 homozygotes in terms of structural and functional features. The vast majority of patients reported improved functional capacity and decreased shortness of breath during the follow-up regardless of ADRB-1 gene polymorphism which is objectively validated by decreased pro-BNP levels in all patients.

Conclusion

Our results indicated that ADRB-1 gene polymorphism, particularly Ser49Gly gene polymorphism may have a significant role during the clinical course of HCM. Since Ser49 homozygote patients demonstrated higher interstitial fibrosis and a higher risk of sudden cardiac death, further studies are required to determine the significance of Ser49Gly gene polymorphism in HCM patients.

Effects of obesity on survival in patients with implantable cardioverter defibrillator

Background

Studies have shown that increased body weight and obesity may be associated with an increased risk of arrhythmic events. However, studies conducted in patients with implantable cardioverter-defibrillator (ICD) have found that low body mass index (BMI) is associated with higher mortality. The aim of this study is to evaluate the effect of obesity on the risk of arrhythmic events, hospitalization and death in patients receiving ICD therapy for primary or secondary prevention.

Methods

The study was designed as a single-center prospective and observational. Patients with BMI <30 kg/m2 were classified as non-obese and patients with ≥30 kg/m2 as obese. The primary endpoints were all-cause mortality, cardiac mortality, and cardiac rehospitalization.

Results

Among the total of 340 patients, 78.2% were male, 21.8% were female, and the mean age of the patients was 60.9 years. Among all patients, there were 30.6% normal weight, 47.4% overweight and 22.1% obese patients. AF recording was significantly higher in obese patients compared to the normal weight patient group (p=0.02). Shock, appropriate shock, and liquid load sensing were statistically higher in obese than non-obese patients (p=0.042, p=0.011 and p=0.007). In the primary prevention group, all-cause mortality and cardiac mortality rates were lower in the obesity group (p=0.022, p=0.037).

Conclusion

Our findings showed that although cardiac arrhythmic events are more common in obese patients, mortality and hospitalization events are less common in obese patients. These findings are consistent with the reverse epidemiology that has been demonstrated previously between obesity and mortality

Cumulative Antimicrobial Susceptibility Data of Pseudomonas Aeruginosa Isolates from Cystic Fibrosis Patients: 4-Year Experience

Objective Pseudomonas aeruginosa is the most important cause of lung infection among cystic fibrosis (CF) patients, and to reduce the severity of the infection, facility-specific cumulative antibiograms could help clinicians in empirical treatment.

Methods Respiratory samples of CF patients between January 2015 and December 2018 were scanned through Laboratory Operating System retrospectively. Demographical data of patients, culture results, and antibiotic susceptibilities are recorded using Microsoft Excel 2010. Cumulative antibiogram data were obtained according to the CLSI M39A4 document.

Results The number of registered patients increased in 4 years from 154 to 253. The mean age of patients varied from 9 to 11.7 (range, 2–42). The ratio of patients with a positive culture for P. aeruginosa increased from 32 to 40%, and the mean patients' age decreased from 16.6 to 11.1 (p <0.05). A total number of 4,146 respiratory samples were analyzed. Sputum samples consisted of 42.5% (n: 1,767) of the samples with a 58.4% isolation rate of P. aeruginosa (n: 1,034). A notable increase of resistance was seen almost all antimicrobials tested by years. The ratio of multidrug-resistant (MDR) P. aeruginosa was 4.1, 10.2, 4.5, and 8.6% in 2015, 2016, 2017, and 2018.

Conclusion Antimicrobial resistance is a challenging problem in CF patients, and surveillance should be done regularly.

First analysis of the Severe Paediatric Asthma Collaborative in Europe registry

New biologics are being continually developed for paediatric asthma, but it is unclear whether there are sufficient numbers of children in Europe with severe asthma and poor control to recruit to trials needed for registration. To address these questions, the European Respiratory Society funded the Severe Paediatric Asthma Collaborative in Europe (SPACE), a severe asthma registry. We report the first analysis of the SPACE registry, which includes data from 10 paediatric respiratory centres across Europe. Data from 80 children with a clinical diagnosis of severe asthma who were receiving both high-dose inhaled corticosteroid and long-acting β2-agonist were entered into the registry between January 2019 and January 2020. Suboptimal control was defined by either asthma control test, or Global Initiative for Asthma criteria, or ≥2 severe exacerbations in the previous 12 months, or a combination. Overall, 62 out of 80 (77%) children had suboptimal asthma control, of whom 29 were not prescribed a biologic. However, in 24 there was an option for starting a licensed biologic. 33 children with suboptimal control were prescribed a biologic (omalizumab (n=24), or mepolizumab (n=7), or dupilumab (n=2)), and for 29 there was an option to switch to a different biologic. We conclude that the SPACE registry provides data that will support the planning of studies of asthma biologics. Not all children on biologics achieve good asthma control, and there is need for new trial designs addressing biologic switching.

Comparison of upper extremity versus lower extremity vein injections of bubble contrast in assessment of patent foramen ovale

Background

Patent foramen ovale (PFO) is one of the causes of cardioembolism and closure of PFO is recommended by the current guidelines in patients with recurrent stroke. Transoesophageal echocardiography (TEE) using bubble-contrast study is the gold standard imaging modality for the assessment of interatrial septum. Upper-extremity veins are the most common way of injection, however, the presence of Eustachian valve and flow dynamics when bubble-contrast injection performed via upper extremity veins limits the assessment of interatrial septum in several cases. In this study, we aimed to compare the efficacy of bubble-contrast study between upper extremity injection and lower extremity injection.

Material/Methods

Patients with a suspicion of cardioembolism who were undergoing TEE study were included in this study. After routine assessment of cardiac structures, the bubble-contrast study was performed using agitated saline from both upper-extremity vein and lower-extremity vein with Valsalva manoeuvre. Right-to-left shunt and numbers of bubbles transmitted from the septum were recorded.

Results

We prospectively included 45 patients and 21 PFOs were detected. There were 9 patients with prominent Eustachian valve and in 6 patients Eustachian valve hampered the complete opacification of the right atrium. In 3 patients flow from the superior vena cava was directed towards the tricuspid valve and hampered the complete opacification. Among 21 patients with PFO, in 6 patients right-to-left shunt was not observed when agitated-saline was injected via the upper-extremity vein, however, the shunt was observed when the agitated-saline was injected via the lower-extremity vein. In 14 patients amount of bubbles passing through the interatrial septum were significantly higher when the injection was performed via the lower-extremity vein especially in patients with prominent Eustachian valve.

Conclusion

Our preliminary results indicated that compared to upper-extremity veins, injection via the lower-extremity veins provides better opacification of right atrial septum and assessment of interatrial septum. Therefore, injection through the lower-extremity veins would be the preferred choice particularly in patients with prominent Eustachian valve or downward directed flow from the superior vena cava.

The clinical significance and prognostic value of early second peak of hs-troponin t in patients successfully treated with primary pci

Background

It was previously demonstrated that in patients with ST segment elevation myocardial infarction (STEMI) high-sensitive troponin-T (Hs-cTnT) makes two peaks. However, the clinical significance of the second peak (early vs late) in patients undergoing successful primary percutaneous intervention (pPCI) is not known. We investigated the role of early second peak on clinical outcomes.

Methods

Patients who underwent successful pPCI were included. Baseline characteristics, angiographic variables and kinetics of Hs-cTnT levels following pPCI were recorded. Second peak of Hs-cTnT was defined as re-elevation of troponin levels above plateau levels. The second peak of Hs-cTnT is defined as early second peak, if re-elevation is detected earlier than 72 hours after the diagnosis and late second peak, when re-elevation is detected later than 72 hours.

Results

We included 250 patients divided into two groups; patients with early second peak as group 1 (n=118) and rest of the patients as group 2 (n=132). Baseline characteristics and comorbidities were similar. Peak level of Hs-cTnT, Hs-CRP and pro-BNP levels were significantly lower in group 1 patients. Left ventricular ejection fraction was higher in group 1 patients (47.48±7.7 vs 43.80±9.3, p-value: 0.001). There was no significant difference with respect to new-onset heart failure (24% vs %28, p: 0.503) between groups however cardiac mortality was significantly lower in group 1 patients (%2 vs %11, p: 0.007).

Conclusion

The early second peak of Hs-cTnT in patients with STEMI is associated with successful reperfusion and predictors of better clinical outcome. Moreover, early second peak of Hs-cTnT is associated with decreased cardiac mortality and has a potential to be used as a marker of good prognosis.

Severe Paediatric Asthma Collaborative in Europe (SPACE): protocol for a European registry

The development of new asthma biologics and receptor blockers for the treatment of paediatric severe asthma raises challenges. It is unclear whether there are sufficient children in Europe to recruit into randomised placebo-controlled trials to establish efficacy and safety in this age group. In February 2016, the European Respiratory Society funded a clinical research collaboration entitled "Severe Paediatric Asthma Collaborative in Europe" (SPACE). We now report the SPACE protocol for a prospective pan-European observational study of paediatric severe asthma. Inclusion criteria are: 1) age 6-17 years, 2) severe asthma managed at a specialised centre for ≥6 months, 3)clinical and spirometry evidence of asthma, and 4) reaching a pre-defined treatment threshold. The exclusion criterion is the presence of conditions which mimic asthma symptoms. Eligible children will be prospectively recruited into a registry, recording demographics, comorbidities, quality of life, family history, neonatal history, smoking history, asthma background, investigations, and treatment. Follow-up will provide longitudinal data on asthma control and treatment changes. The SPACE registry, by identifying well-phenotyped children eligible for clinical trials, and the amount of overlap in eligibility criteria, will inform the design of European trials in paediatric severe asthma, and facilitate observational research where data from single centres are limited.

Comparison of the effects of voluntary termination of pregnancy and uterine evacuation for medical reasons on female sexual function

OBJECTIVE

A wide spectrum of emotions are experienced during abortion, including anxiety, sadness and grief, guilt, pessimism about future pregnancies, disturbed self-perception and loss of confidence in intimate relationships. This study aimed to compare the short-term effects of legal voluntary termination of pregnancy with uterine evacuation for medical reasons on female sexual function.

STUDY DESIGN

The study group was comprised of 50 patients admitted to the Family Planning Clinic for legal voluntary termination of pregnancy <10 weeks of gestation, and the control group was comprised of 50 patients who underwent manual vacuum aspiration of the products of conception for medical reasons (e.g. inevitable abortion, incomplete abortion, fetal abnormality and teratogenic drug use). Female sexual function in the two groups was evaluated using the Golombok-Rust Inventory of Sexual Satisfaction (GRISS). GRISS scores immediately before and 3 months after termination of pregnancy were compared within each group and between the two groups.

RESULTS

Mean total GRISS scores before and after termination of pregnancy were 5.33 and 8.12 in the study group, and 6.02 and 6.4 in the control group, respectively (p<0.05). The increase in GRISS scores for both groups indicated deterioration in sexual function (p=0.000 and p=0.016, respectively). Three months after termination of pregnancy, the total GRISS score was significantly higher in the study group compared with the control group (8.12 vs 6.4, p<0.05).

CONCLUSION

Female sexual dysfunction is a complicated concept that is affected by multiple factors over a woman's lifetime. It is important to consider female sexual function as a part of reproductive health, with a close relationship with contraception. As such, patients should receive counselling about sexual function and contraception as part of comprehensive abortion care.

Reproductive performance after hysteroscopic metroplasty in infertile women: complete versus partial uterine septum

OBJECTIVE

To investigate the impact of hysteroscopic metroplasty on pregnancy outcome in women with complete or incomplete uterine septum (US) accompanying infertility.

MATERIALS AND METHODS

Seventy-three patients who had hysteroscopic metroplasty for complete and incomplete US with primary and secondary infertility were reviewed. Obstetric outcomes (number of pregnancies, live births, and miscarriages) up to 36 months follow up period were investigated.

RESULTS

Twenty-five patients in complete US and 28 patients in incomplete US became pregnant in 36 months follow up. Postoperative miscarriage rate was significantly lower in patients with complete US (p = 0.0001,p = 0.0001, respectively). The mean gestational week at the time of birth and mean birth weight of the in- fants were significantly lower in patients with complete US compared to the incomplete US cases (p = 0.026, p = 0.049, respectively). Postoperative pregnancy rate was significantly lower in incomplete US patients with primary infertility compared with secondary in- fertility (p = 0.037).

CONCLUSION

Hysteroscopic metroplasty improves fertility and pregnancy performance. This improvement is more prominent in patients with complete US, and incomplete US patients with secondary infertility.

Prognostic utility of serum vitronectin levels in acute myocardial infarction

BACKGROUND

Vitronectin (VN) functions as a regulator of platelet adhesion and aggregation, coagulation, and fibrinolysis. The aim of this study was to assess the prognostic significance of serum VN levels in patients with acute myocardial infarction (MI).

METHODS

In this study 62 patients admitted with ST-elevation myocardial infarction (STEMI), or non-ST-elevation myocardial infarction (NSTEMI) were enrolled. Serum VN levels were measured within 6 h after onset of chest pains.

RESULTS

The VN serum levels were higher in MI patients with a mean of 2.257 µg/ml (range 1.541-4.493 µg/ml) in the STEMI group, 1.785 µg/ml (range 1.372-4.113 µg/ml) in the NSTEMI group, and 1.222 µg/ml (range 1.033-1.466 µg/ml) in the controls (p = 0.012). Major adverse cardiovascular events could be predicted at 6 months using VN levels independently of other variables [odds ratio (OR) 9.87, 95 % confidence interval (CI) 2.54-47.37, p = 0.001]. There was a significant positive correlation between VN levels and the Gensini score in NSTEMI patients (r = 0.436, p = 0.013).

CONCLUSION

The VN level may be relevant as a clinical biomarker for adverse cardiovascular outcomes not only in patients with ischemic heart disease undergoing coronary interventions, as previously reported, but also in coronary artery disease patients presenting with acute MI.

Related factors of dental caries and molar incisor hypomineralisation in a group of children with cystic fibrosis

AIM

To investigate dental caries and molar incisor hypomineralisation (MIH)-related factors such as treatment, diet, brushing and salivary factors in children with cystic fibrosis (CF) compared with healthy peers.

STUDY DESIGN

A cohort study was performed.

METHODS

This study was performed on 30 CF children comprising patients at the Faculty of Medicine and 30 control children recruited from the Dental School. Salivary factors, dental caries, MIH, daily diet, brushing habits were analysed. Statistical analysis was calculated by SPSS for Windows.

RESULTS

Decay missing filled teeth (DMF-T) score was 4.6 ± 4.0 in CF and 7.7 ± 2.7 in control (p = 0.001). 43% of CF children with MIH were found to use antibiotics, but no significant difference in the caries experience was found with antibiotic usage (p > 0.05). DMF-T of CF adolescents (23%) who use Tobramycin was 7 ± 3.5. DMF-T of CF children (20%) who take other antibiotics was 2.5 ± 3.5, but no statistical difference was found (p = 0.054). Saliva pH, salivary flow rate, and buffering capacity were not found statistically significant (p > 0.05).

STATISTICS

Percentage arithmetic mean value, standard deviation, independent sample t test, Fisher's exact test, Chi-square test and Mann-Whitney U test were used, while a p value of <0.05 was considered statistically significant.

CONCLUSIONS

Medication and diet could be considered as a risk factor for dental caries and factors such as salivary pH, good oral hygiene could play a protective role for oral health CF children. MIH frequency and lower caries experience seen in CF children could be due to salivary factors or pharmacological treatment they take. The multidisciplinary approach team would be advantageous in the management of children with CF and oral health should be under control during early years of life by paediatric dentists.

Correlations between sarcopenia and hypertensive target organ damage in a Turkish cohort

AIMS

To investigate a possible correlation between skeletal muscle mass and hypertensive target organ damage.

MATERIALS AND METHODS

A total of 365 hypertensive patients aged > 18 years were included (221 females; 144 males). Exclusion criteria were: diabetes; hypo- or hyperthyroidism; immobilisation; leg amputation; dehydration; cancer diagnosis; renal insufficiency with GFR of <60 ml/ dk/1.73 m2; and hormone replacement therapy. All patients who participated in the study were examined for the presence of hypertensive retinopathy and nephropathy and divided into four groups according to age and sex (group 1 = females aged <60 years; group 2 = females aged >60 years; group 3 = males aged <60 years; and group 4 = males aged > 60 years). The diagnosis of hypertensive nephropathy and retinopathy was based on spot urine microalbuminuria/creatinine ratio and opthalmoscopy, examination respectively. Body composition was evaluated using bioimpedance analysis (BIA). Fullbody skeletal muscle mass (SMM) and SMM index (SMMI) were used as indicators of skeletal muscle mass.

RESULTS

As expected, female and elderly subjects showed a decreased skeletal muscle mass and increased fat mass compared to males and younger subjects. In the overall cohort, a negative correlation was found between skeletal muscle mass and both hypertensive retinopathy and nephropathy. Subgroup analysis revealed a linear correlation between increased SMM and a decreased risk of hypertensive retinopathy. Patients with a spot urine microalbuminura/creatinine ratio of > or = 30 had a lower SMM and a lower SMMI than patients with a ratio of <30.

CONCLUSION

In the present cohort, sarcopenia mainly due to aging was associated with an increased rate of hypertensive target organ damage in the form of hypertensive retinopathy and nephropathy

Factors affecting pregnancy outcome of intrauterine insemination cycles in couples with favourable female characteristics

The aim of the presented study is to determine the effect of different sperm parameters on the pregnancy rate of intrauterine insemination (IUI) cycles in women with favourable fertility characteristics treated for infertility. Medical records of 212 infertile couples who had undergone a total of 253 cycles were reviewed retrospectively. Inclusion criteria for women were age <35 years, antral follicle count >5, FSH <15 IU/ml, and at least one patent tube documented by HSG or laparoscopy. Clinical pregnancy rates were achieved as 15.8% per cycle, and 18.8% per couple. Woman's age, partner's age, total number of motile sperm (TMS) and motility, significantly influenced pregnancy rate. Pregnancy rate was the highest when women were aged <25 and TMS >10 × 10(6). Partner's age significantly affected the pregnancy rate per cycle in women aged <30 years and TMS >10 × 10(6). Woman's age (OR: 5.4 95% CI: 1.2-24.3) and TMS (OR: 0.06 95% CI: 0.003-0.89) were predictor variables as regards to pregnancy. Pregnancy rate was the highest in IUI cycles when woman was <25 years old, TMS was >10 × 10(6), and morphology was >4%. Male age was found to be another determining factor for IUI success, even if they had a normal spermiogram.
