Abstract
BACKGROUND Cystic fibrosis (CF, or mucoviscidosis) is one of the rare diseases with a fatal course and with the highest prevalence. Formerly known as a purely childhood disease, this multisystemic disease follows an autosomal recessive inheritance pattern and results in a malfunction of the cystic fibrosis transmembrane conductance regulator (CFTR) channel, leading to the production of viscous secretions. The prognosis and outcome of CF are determined by the severity of the involvement of the lungs. Other typically affected organs include the pancreas, liver and intestines. OBJECTIVE This article reviews the clinical presentation and evolution of CF with a focus on the new era of the highly effective CFTR modulator treatment. MATERIAL AND METHODS An overview of the current state of knowledge on the care for CF patients is presented. RESULTS AND DISCUSSION The introduction of the CF newborn screening, the increased understanding of the disease and the development of novel treatment options have substantially increased the quality of life and life expectancy of people with CF. As a result, more than half of CF patients in Germany are now older than 18 years of age and the complications of a chronic disease as well as organ damage due to the intensive treatment are gaining in importance. The highly effective CFTR modulator treatment results in a significant improvement in CFTR function, lung function, body mass index and quality of life and is available to approximately 90% of patients in Germany, based on the genotype. Nevertheless, further research including the development of causal treatment, e.g., gene therapy, targeting the underlying defect in the remaining 10% of CF patients, is urgently needed. Even in adult patients, CF with a mild course or a CFTR-related disease should be considered, e.g., in cases of bronchiectasis and/or recurrent abdominal complaints.

Abstract
PURPOSE OF REVIEW Traditional cystic fibrosis (CF) care had been focused on early intervention and symptom mitigation. With the advent of highly effective cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapy (HEMT), in particular, the approval of elexacaftor/tezacaftor/ivacaftor in 2019, there has been a dramatic improvement in outcomes in CF. The purpose of this article is to review the benefits, limitations, and impact of HEMT as well as discuss the new implications, challenges, and hope that modulators bring to people with CF (pwCF). RECENT FINDINGS HEMT has demonstrated sustained improvement in lung function, nutrition, quality of life, and survival for over 90% of pwCF. As HEMT has delivered such promise, there is a small but significant portion of pwCF who do not benefit from HEMT due to ineligible mutations, intolerance, or lack of accessibility to modulators. SUMMARY HEMT has significantly improved outcomes, but continued research is needed to understand the new challenges and implications the era of HEMT will bring, as well as how to provide equitable care to those who are unable to benefit from HEMT.

Abstract
PURPOSE OF REVIEW With improved long-term survival and the expanding availability of cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies that treat the underlying genetic defect in cystic fibrosis, more people are interested in parenthood. Cystic fibrosis care centers and people with cystic fibrosis need more information to guide decisions related to parenting. RECENT FINDINGS Here we present currently available data on fertility, pregnancy, and parenthood in the modern era of cystic fibrosis care. Fertility may be improving in female individuals with cystic fibrosis with the use of CFTR modulator therapies, and there is an associated increase in annual pregnancies. Infertility in male individuals with cystic fibrosis remains approximately 97-98% and is unchanged with CFTR modulators in those already born with cystic fibrosis. As more female individuals with cystic fibrosis experience pregnancy, questions remain about the impact of pregnancy on their health and that of their child. Fortunately, there are multiple routes to becoming a parent; however, more work is needed to understand the impact of pregnancy and parenthood in the context of CF as some previous data suggests potential challenges to the health of parents with cystic fibrosis. SUMMARY We encourage cystic fibrosis care teams to have knowledge and resources available to support the reproductive goals of all individuals with cystic fibrosis.

Abstract
Cystic fibrosis (CF) is a chronic condition requiring continued input from the CF dietitian as an integral part of the CF multidisciplinary team. In recent years, the longer life expectancy experienced by people with CF (PwCF) means that nutrition advice and therapy are evolving from a focus on nutrition support to prevention and management of comorbidities. Little has been reported regarding the perceived role of the CF dietitian amongst PwCF. We report the responses to 11 questions that were part of a larger international survey distributed to members of national CF charities in 2018-2019. These questions evaluated PwCFs' perspectives on (i) the importance of the CF diet, (ii) how often PwCF obtain dietary/nutritional advice from their dietitian, (iii) the perceived reliability of information given by the dietitian, (iv) other sources of CF information and their perceived reliability, and (v) how CF nutrition/diet, as well as CF-related diabetes, ranked as research priorities. There were 295 respondents from 13 countries. Almost half of the respondents (46.8%) contacted their CF dietitian on a frequent/more regular basis, compared to medical/scientific journals/medical/scientific search engines. The CF dietitian was considered a reliable source of information, as 84% of the respondents indicated that the information provided was very/generally reliable. At a time when CF care and expectations are changing rapidly, PwCF are in need of trusted and reliable information to make positive changes in lifestyle and habits. Dietitians working with PwCF should appreciate the pivotal and valued role they perform as purveyors of robust evidence-based information to this chronic disease population.

Abstract
With the advent of highly effective modulator therapies, many people with cystic fibrosis (CF) are living longer, healthier lives. Pregnancy rates for women with CF more than doubled between 2019 and 2021, reflecting increases in both planned and unplanned pregnancies. For men with CF, CF-associated infertility can be mitigated with assistive reproductive technology, yet patient knowledge of these challenges and options is variable. Preconception and prenatal counseling for individuals with CF and for parents of children with CF who wish to expand their families requires nuanced discussions to promote informed reproductive decisions, drawing from a combination of standard practice recommendations and CF-specific assessments. This review article synthesizes the current literature and practice recommendations regarding reproductive counseling and care in CF, outlining the role of genetic counseling, carrier screening, teratogen counseling, in vitro fertilization and pre-implantation genetic diagnosis, and careful assessment and management of cystic fibrosis-related diabetes when present. Via a multidisciplinary, patient-centered approach, clinicians can support adults with CF and parents of children with CF as they make informed reproductive decisions and embark on family planning.

Abstract
The introduction of mutation-specific therapy led to a revolution in cystic fibrosis (CF) care. These advances in CF therapies have changed the disease profile from a severe incurable disease with limited survival to a treatable disease with improved quality of life and survival into adulthood. CF patients are now able to plan their future, including marriage and parenthood. Side by side with the optimism, new issues and concerns are arising, including fertility and preparation for pregnancy, maternal and fetal care during pregnancy, and post-partum care. While cystic fibrosis transmembrane regulator (CFTR) modulators show promising results for improving CF lung disease, data on their safety in pregnancy are still limited. We performed a literature review on pregnancy in CF from the past, with the first described pregnancy in 1960, through the current fascinating changes in the era of CFTR modulators, to ongoing studies and future directions. Current advances in knowledge give hope for improved outcomes of pregnancy, towards the best possible prognosis for the mother and for the baby.

Abstract
Prior to the twentieth century, pregnancy and childbirth were highly risky endeavours for any woman in even the most advanced societies. As recently as 1900, maternal mortality in the UK ran at close to five deaths per 1000 births, and was even higher in the USA [1]. Such a death toll would be inconceivable in the developed world now, and the transformation of societal expectations around childbirth, from an event of fear and great hazard to a joyous bonding experience, may represent one of the great achievements of modern healthcare. Respiratory disorders are common in pregnant women, but their exclusion from clinical trials makes decisions around pharmacotherapy challenging. Developing programmes designed to improve evidence in pregnancy should be a priority for respiratory research.https://bit.ly/3n6aX42
