Application of health technology assessment: a new need for an ethical neonatology.

New health technologies are constantly developing. However, their impacts on health and implications for health systems are not always clear. Faced with this situation, in the last 45years, Health Technology Assessment (HTA) has taken an important role in the decision-making process related to the implementation of technologies in healthcare systems. According to the Core Model® EUnetHTA, a "full HTA" should cover nine domains: health problems and current use of technology, description and technical characteristics, safety, clinical effectiveness, costs and economic evaluation, ethical analysis, organizational aspects, patients and social aspects, legal aspects. In all domains of a HTA, the approach is evidence-based and uses epidemiological data, systematic reviews to gather the best level of proofs regarding clinical efficacy and safety of interventions and comparators and organizational and economic models. One exception is the ethical analysis, that uses value-based approach. Although in Neonatal Intensive Care Units (NICUs) there are highly advanced technological environments, HTA has not yet been widely used in this field for determining the "value" of the diagnostic and therapeutic procedures. An example of diagnostic tool used in NICUs is the near-infrared spectroscopy (NIRS), a noninvasive device that enables real-time monitoring of the condition of peripheral tissues in critically ill newborns. The availability of this diagnostic tool could improve the choice of the most appropriate treatment to the clinical situation of the newborn. The expected benefit of NIRS motivates the need of a full HTA. Conclusion: HTA is still little used in Neonatal Critical Care, but it may be the appropriate tool to determine the "value" of technologies used in this field. The implementation of clinical trials and HTA may help in an evidence-based evaluation of new technologies for the neonatal critical care. This could facilitate the rapid introduction of the best health technologies into clinical practice. What is Known: • Health Technology Assessment (HTA) has taken an important role in the decision-making process related to the implementation of technologies in healthcare systems • The centrality of ethics in HTA has been known. In fact, ethics is everywhere in HTA, and value judgments permeate all levels of HTA What is New: • HTA is still little used in Neonatal Critical Care, but it may be the appropriate tool to determine the "value" of technologies used in this field • The implementation of clinical trials and HTA may help in an evidence-based evaluation of new technologies for the neonatal critical care and in introduction of the best and ethically acceptable health technologies into clinical practice.

Gas repellents herbal drugs could induce hyperkalemia in infants: case series in tertiary centers in Saudi Arabia

This is a case series involving four infants who experienced hyperkalemia (high levels of potassium in the blood) after using herbal gas repellents that contained potassium sorbate as an antimicrobial preservative. The first patient was a ten-day-old male who presented with jaundice and incidental hyperkalemia, which resolved with treatment. The second patient was a three-month-old male who had a history of neonatal critical care admission and presented with vomiting and incidental hyperkalemia, which resolved spontaneously. The third patient was a two-month-old female who presented with failure to thrive and incidental hyperkalemia, which resolved after discontinuation of the herbal gas repellent. The fourth patient was a one-month-old male who presented with vomiting and incidental hyperkalemia, which also resolved after discontinuation of the herbal gas repellent. All patients underwent investigations to determine the underlying cause of hyperkalemia, but no specific cause was found other than the use of the herbal gas repellents. The abstract highlights the importance of physicians being aware of the potential effects of potassium-containing herbal gas repellents and the occurrence of unexplained hyperkalemia in infants, urging caution in their use.

Assessment of Nurse's Knowledge toward Human Herpes Virus 6 HHV-6 Infection in NICU

Background: The infant contracted Herpes Simplex Virus (HSV) during the process of being born. The worldwide occurrence of NH is approximately 10 cases per 100,000 births, and it is associated with substantial risks of illness and death. Objective: To evaluate nurses' level of understanding regarding HHV-6 infection in the neonatal intensive care unit (NICU) for newborn infants. The study employed a descriptive research design methodology to achieve its objective. A representative sample of 50 nurses currently employed in neonatal critical care units. Tool I: An Arabic-language structured interview questionnaire. The study encompassed many demographic factors of nurses, such as gender, age, educational attainment, years of experience in the Neonatal Intensive Care Unit (NICU), completion of training on HHV-6 infection, and the source of information. The second tool, the knowledge assessment sheet, focused on HHV-6 infection. The findings indicate that the study included exclusively female nurses, comprising 46.0% of the sample, while males accounted for 54%. Furthermore, the educational background of the participants primarily consisted of graduates from nursing institutes and colleges, with each group representing a substantial proportion of 34%. Conclusion: Our findings indicate that we have chosen to dismiss the null hypothesis, which posits that there is no correlation between the demographic attributes of nurses and their degree of understanding regarding herpes virus type 6 infection. Instead, we have opted to embrace the alternative hypothesis. Recommendations: Provide nurses with a thorough knowledge of the viral causes and risk factors linked to HSV type 6 infections in pregnant women.

Artificial Intelligence Applications in Neonatal Critical Care: A Scoping Review

Background: The development of artificial intelligence (AI) approaches impacted drug discovery, medical imaging, customized diagnostics, and therapeutics. Medicine will be transformed by AI. One such area of medicine where AI is significantly improving care is neonatology. Objective: The objective of this scoping review is to explore the applications of AI in neonatal critical care and its outcome. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a scoping review was conducted utilizing the Web of Science, MEDLINE (PubMed), and Scopus databases. The search was limited to full-text publications on AI applications in neonatal critical care that were published between January 1, 2019, and December 31, 2023. Articles specifically addressing the application of AI in neonatal care have been considered within the scope of this review. At least three reviewers had independently executed the screening, data abstraction, and exploration. Results: Database searches yielded 631 articles, of which 11 met the inclusion criteria. The research encompassed extensive AI applications in neonatal critical care, employed for prognosis, diagnosis, and therapy strategizing. Artificial neural networks, machine learning, deep learning, and shallow hybrid neural networks were the commonly utilized AI techniques (neonatal critical care). These methods were applied to screen for inborn metabolic abnormalities, predict various outcomes, including death and sepsis, identify diseases such as sepsis, and assess neurodevelopmental outcomes in preterm newborns, helping plan several medical treatments. The included research demonstrated encouraging outcomes when using AI in neonatal critical care. Conclusions: AI-driven electronic arrangements upgrade neonatal basic care by improving risk forecast, promising critical commitments to future health care. Be that as it may, careful appraisal, evidence-based considers, and determination of safety, ethics, and information straightforwardness issues are essential before implementation. Acceptance by administrative bodies and the therapeutic community pivots on tending to these concerns.

PICNIC Unconference: Growing a community of practice for psychological professionals working in paediatric and neonatal critical care

In September 2023, 58 psychological professionals from across the UK and Republic of Ireland convened for an ‘Unconference’ event in Birmingham to strengthen their developing community of practice in paediatric and neonatal critical care settings. This article describes the origins, purpose, format, content and evaluation of the Unconference, providing a map for groups to follow when organising such events in the future including helpful routes to take and pitfalls to avoid.

Association Between Antibiotic Duration and Recurrence of Urinary Tract Infection in the Neonatal Critical Care Unit.

Urinary tract infection (UTI) is the most common bacterial infection in infants. Current practice guidelines suggest a treatment duration of 7 to 14 days. Suboptimal therapy may increase the risk for recurrent UTIs leading to renal scarring and possibly chronic kidney disease. The primary objective is to evaluate the duration of therapy for UTIs and its association with the incidence of recurrent UTIs in a neonatal intensive care unit (NICU). The secondary objectives are to identify the risk factors and the most common organisms for recurrent UTIs. Patients were identified via the diagnosis codes for UTIs and were included if admitted to the NICU and if they received antibiotics prior to hospital discharge. Patients were divided into 2 groups: antibiotic treatment for 7 days or fewer and antibiotic treatment for greater than 7 days. Eighty-six infants were included in the study. Twenty-six patients received antibiotics for 7 days or fewer, and 60 for more than 7 days. In the study, the median birth weight was 977 g and the median gestational age was 27.6 weeks. There was no significant difference in the rate of recurrent UTIs between the 2 groups (p = 0.66). However, in the subgroup analysis, the incidence was higher for patients receiving antibiotic therapy for fewer than 7 days versus 7 days (p = 0.03). There was no difference in recurrence of UTI between treatment groups (≤7 days versus >7 days), and recurrence was seen in a higher percentage of patients with a urinary tract anomaly.

Magnitude of preterm birth and associated factors Among mothers who gave birth in Debre Berhan comprehensive specialized hospital.

Premature deliveries are a major public health issue, with high health, economic, and productivity costs associated with lengthy hospitalizations in neonatal critical care units. The goal of this study was to determine the number of premature births in Ethiopia's Debre Berhan Comprehensive Specialized Hospital and the factors that influence them. The Debre Berhan Comprehensive Specialized Hospital conducted an institution-based cross-sectional study between February and April 2020. A total of 325 study participants were selected using systematic random sampling. Face-to-face interviews using a pre-tested semi-structured questionnaire were used to collect data. For data entry and analysis, Epi data version 3.1 and SPSS version 20 were used. At a P-value of 0.2, bivariate logistic regression analysis was used to categorize candidate variables to the next level, and variables in multivariate logistic regression models with a p-value of 0.05 were considered statistically significant. Preterm births accounted for 16.1% of all births at Debre Berhan Comprehensive Specialized Hospital. Cesarean section [AOR = 2.412; 95% CI (1.154, 5.0370)], twin pregnancy [AOR = 3.524; 95% CI (1.114, 11.150)], and maternal anemia during pregnancy [AOR = 3.124; 95% CI (1.417, 6.887)] were statistically significant associations with the outcome variable in the final logistic regression model. Preterm birth was found to be greater in the study area than in the Global Action Report for Sub-Saharan Africa and a few other countries. Efforts should be made to prevent maternal health issues that lead to caesarean section, and all pregnant mothers should be supplemented with iron and folic acid as soon as feasible. This study suggests that there is still a gap in the field in terms of health service intervention.

Retinopathy of Prematurity in Neonatal Intensive Care Unit at King Fahd University Hospital, Eastern Province: Prevalence, Risk Factors, and pattern of severity Seven years’ experience.

Background Premature newborns are susceptible to retinopathy of prematurity (ROP), a vasoproliferative disease of the developing retinal vessels, which is a major cause of potentially avoidable blindness. Due to geographical variations in newborn care, geographic variations in the epidemiology of ROP have been observed internationally during the last several decades. There was a correlation between the severity of the condition and the number of prenatal, postnatal, and other risk factors. This study aimed to examine the incidence and risk factors associated with retinopathy of prematurity in preterm infants. Methods A retrospective review of preterm newborns evaluated for retinopathy of prematurity between January 2016 and December 2022 was carried out at King Fahd Hospital of the University (KFHU), Khobar, Saudi Arabia. Infants who fulfilled the screening criteria (GA < 34 or Birth Weight (WT) ≤ 1500 g) underwent the screening test, and the International Classification of Retinopathy of Prematurity was used to classify retinopathy of prematurity. Risk factors and demographic information regarding ROP were assessed. Statistical analysis was performed using SPSS (version 20) with a 95% confidence interval (CI). Statistical significance was set at p < 0.05. Results Among the 200 preterm neonates that were evaluated and admitted to neonatal critical care units, 37% exhibited premature retinopathy, with 46.7% of those cases being in stage 1. The development of ROP was linked to gestational age, length of mechanical ventilation, septicemia, intraventricular hemorrhage, bronchopulmonary dysplasia, respiratory distress syndrome, and septicemia, according to univariate and multivariate logistic regression analyses. Conclusion The incidence of total retinopathy in premature infants in this population was 37%. Evaluating these risk factors during the screening of high-risk premature infants will help determine the appropriate timing of examinations and treatment.

Point-of-Care Ultrasound (POCUS) Training Curriculum for Pediatric Nephrology: PCRRT-ICONIC Group Recommendations.

Point of care ultrasound (POCUS) is commonly used in adult specialties, pediatric emergency medicine, and neonatal and pediatric critical care. Specifically, in the field of pediatric nephrology, POCUS plays a valuable role in the critical inpatient and outpatient settings. However, the lack of guidelines and a standardized curriculum for POCUS in pediatric nephrology has led to substantial discrepancies in both clinical practice and training. A multinational, multicenter survey regarding POCUS usefulness and training was sent to 225 pediatric nephrology residents, fellows, and physicians with expertise in pediatric nephrology. Based on the results, an ideal pediatric nephrology POCUS curriculum was formulated with a panel of experts from across the world. Eighteen experts were included, with each expert having greater than 10 years of experience in using POCUS in adult and pediatric nephrology. A Delphi method was utilized to further solidify guidelines regarding the content, curriculum, and vital skills of using POCUS in pediatric nephrology. A total of 134 pediatric nephrology trainees, specialists, and faculty responded to the survey (59.6% completion rate). A total of 87.4% of respondents believe that formal POCUS training is either highly desirable or should be mandatory in pediatric nephrology fellowship programs. Identified barriers to receiving training included lack of an organized curriculum, lack of POCUS experts and Pediatric intensivists, lack of ultrasound equipment, lack of financial support, and lack of dedicated time during training. An expert panel was convened and a Delphi survey was conducted to formulate guidelines to overcome the barriers to pediatric nephrology POCUS and standardize the training process. After collaborating with prominent pediatric nephrologists and global POCUS experts proposed a comprehensive POCUS training curriculum tailored specifically for pediatric nephrology trainees, with an appeal for all pediatric nephrology education programs to integrate POCUS instruction into their curricula.

The Prevalence and Associated Risk Factors for Neonatal Thrombocytopenia Among Newborns Admitted to the Neonatal Intensive Care Unit.

Background Thrombocytopenia is the most prevalent hematological condition in neonates that develops in the neonatal intensive care unit (NICU). This set of illnesses is caused by either decreased platelet production due to placental insufficiency, increased platelet breakdown (consumption), or a combination of the two causes. Based on platelet count, it is defined as mild, moderate, or severe thrombocytopenia, with early and late onset. Purpose The purpose of this study is to determine the prevalence of thrombocytopenia and the factors that contribute to it in newborns hospitalized in the neonatal critical care unit at the Maternity and Children Hospital in Al Ahsa, Saudi Arabia. Methods This descriptive retrospective cross-sectional study was carried out at the NICU of the Maternity and Children Hospital in Al Ahsa, Saudi Arabia, over the span of one year (August 2022 to August 2023) among hospitalized neonates with thrombocytopenia. Thrombocytopenia is defined as a platelet count of 150,000 or less. These patients were monitored until they recovered or died. Results The inclusion criteria were met by a total of 242 newborns with thrombocytopenia. Half of the neonates (57%) were full-term, with Apgar scores greater than 5 at the first (84%) and fifth (93%) minutes, respectively. The great majority of individuals (84%) experienced early-onset thrombocytopenia of mild severity (62%) and were asymptomatic (93%). The majority of the cases resolved spontaneously, with only 21%requiring platelet transfusion. There was a significant relationship discovered between gestational age and the severity of thrombocytopenia, with very preterm infants having moderate to severe thrombocytopenia, as well as birth weight (p=0.001). Furthermore, neonates with severe thrombocytopenia had a considerably higher mortality rate (p=0.001). Conclusion The mortality and morbidity of newborns with perinatal risk for neonatal thrombocytopenia can be reduced with timely detection of the cause and development of thrombocytopenia, as well as adequate and early care.

Training perinatal nurses in palliative communication by using scenario-based simulation: A quasi-experimental study

AimThis study aimed to assess the impact of two educational modules on enhancing the communication confidence, competence and performance of perinatal nurses in the context of palliative care. BackgroundConcerns have arisen regarding the preparedness of perinatal nurses in delivering palliative care, especially in terms of deficiencies in communication skills and negative attitudes toward making life-support decisions for parents facing neonates with terminal conditions. Bridging this gap necessitates improved perinatal palliative care education for healthcare providers. Research has shown that simulation-based teaching effectively enhances procedural competence, communication skills and confidence among healthcare professionals. However, comprehensive curricula focusing on perinatal palliative communication remain limited. DesignThis study used a quasi-experimental design employing a two-group repeated measure approach. It involved a purposive sample of 79 perinatal nurses from a hospital in northern Taiwan. MethodsA palliative communication course specifically designed for registered nurses in perinatal units was developed. Participants were allocated to either the experimental group (Scenario-Based Simulation, SBS) or the control group (traditional didactic lecture). Communication confidence and competence were assessed before and immediately after the course through structured questionnaires. Learning satisfaction was collected post-intervention and participants underwent performance evaluation by standardized parents one week later. ResultsA significant training gap in palliative care exists among nurses in OB/GYN wards, delivery rooms and neonatal critical care units, highlighting the need for continuing education. All 79 participants completed the training course. Following the intervention, nurses in the SBS group (n=39) exhibited significant improvements in self-reported confidence (p <0.05), competence (p <0.01) and performance (p <0.001) in neonatal palliative communication compared with the traditional didactic lecture group (n=40). The SBS group also received higher satisfaction ratings from nurse learners (p <0.001). ConclusionsThe research findings support scenario-based simulation as a more effective educational approach compared with traditional didactic lectures for enhancing communication confidence and competence. These results were further reinforced by evaluation from standardized patients, highlighting the value of direct feedback in enhancing nurses' performance. Tailoring SBS designs to diverse nursing contexts and incorporating a flipped approach can further enrich the overall learning experience. Given its high effectiveness and positive reception, we recommend integrating this educational module into palliative care training programs for perinatal nurses.

Pericardial Effusion and Superficial Abdominal Abscess as Complications of Malposed PICC Line in a Preterm Neonate: A Case Report

In neonatal critical care units, peripherally inserted central catheter lines are frequently used to provide venous access for continuous parenteral nutrition and medications in newborns. In this case report, a male neonate weighing 1270 grams was on Continuous Positive Airway Pressure (CPAP) for hyaline membrane disease and initially received Total Parenteral Nutrition (TPN) through a Peripherally Inserted Central Catheter (PICC) in the left long saphenous vein on the second day. The baby developed tachycardia, respiratory distress requiring mechanical ventilation, and erythematous swelling over the paraumbilical region. A diagnosis of pericardial effusion and superficial abdominal abscess secondary to a malposed PICC line in a preterm, very low birth weight neonate was made. Suspecting a misplaced line, it was immediately removed, and the patient showed improvement over the next 24 hours. Within the next 48 hours, the patient was extubated to CPAP. Therefore, daily inspection by an expert, as well as confirmation of the central line tip, will aid in preventing delays in detecting complications.

Spiritual Care in PICUs: A U.S. Survey of 245 Training Fellows 2020-2021.

To understand the perspectives of pediatric fellows training in critical care subspecialties about providing spiritual care. Cross-sectional survey of United States National Residency Matching Program pediatric fellows training in critical care specialties. Online survey open from April to May 2021. A total of 720 fellows (165 cardiology, 259 critical care, and 296 neonatology) were contacted, with a response rate of 245 of 720 (34%). None. We assessed fellows' survey responses about spiritual care in neonatal and pediatric critical care units. Categorical data were compared using chi-square test or Fisher exact tests. The Wilcoxon rank-sum test was used to compare the percentage correct on ten multiple-choice questions about world religions. Free-text responses were independently coded by two research investigators. A total of 203 of 245 (83%) responding fellows had never received training about spiritual care and 176 of 245 (72%) indicated that they would be likely to incorporate spiritual care into their practice if they received training. Prior training was associated with increased familiarity with a framework for taking a spiritual history ( p < 0.001) and increased knowledge of spiritual practices that could influence medical care ( p = 0.03). Prior training was also associated with increased self-reported frequency of taking a spiritual history ( p < 0.001) and comfort in referring families to spiritual care resources ( p = 0.02). Lack of time and training were the most reported barriers to providing spiritual care. Providing spiritual care for families is important in critical care settings. In 2020-2021, in the United States, 245 pediatric critical care fellows responded to a survey about spiritual care in their practice and reported that they lacked training in this subject. An opportunity exists to implement spiritual care curricula into pediatric fellowship training.

Long-term healthcare utilization and costs of babies born after assisted reproductive technologies (ART): a record linkage study with 10-years' follow-up in England.

Is the long-term health care utilization of children born after ARTmore costly to the healthcare system in England than children born to mothers with no fertility problems? Children born after ART had significantly more general practitioner (GP) consultations and higher primary care costs up to 10 years after birth, and significantly higher hospital admission costs in the first year after birth, compared to children born to mothers with no fertility problems. There is evidence that children born after ART are at an increased risk of adverse birth outcomes and a small increased risk of rare adverse outcomes in childhood. We conducted a longitudinal study of 368088 mother and baby pairs in England using a bespoke linked dataset. Singleton babies born 1997-2018, and their mothers, who were registered at GP practices in England contributing data to the Clinical Practice Research Datalink (CPRD), were identified through the CPRD GOLD mother-baby dataset; this data was augmented with further linkage to the mothers' Human Fertilisation and Embryology Authority (HFEA) Register data. Four groups of babies were identified through the mothers' records: a 'fertile' comparison group, an 'untreated sub-fertile' group, an 'ovulation induction' group, and an ART group. Babies were followed-up from birth to 28 February 2021, unless censored due to loss to follow-up (e.g. leaving GP practice, emigration) or death. The CPRD collects anonymized coded patient electronic health records from a network of GPs in the UK. We estimated primary care costs and hospital admission costs for babies in the four fertility groups using the CPRD GOLD data and the linked Hospital Episode Statistics (HES) Admitted Patient Care (APC) data. Linear regression was used to compare the care costs in the different groups. Inverse probability weights were generated and applied to adjust for potential bias caused by attrition due to loss to follow-up. Children born to mothers with no fertility problems had significantly fewer consultations and lower primary care costs compared to the other groups throughout the 10-years' follow up. Regarding hospital costs, children born after ART had significantly higher hospital admission costs in the first year after birth compared to those born to mothers with no fertility problems (difference = £307 (95% CI: 153, 477)). The same pattern was observed in children born after untreated subfertility and ovulation induction. HFEA linkage uses non-donor data cycles only, and the introduction of consent for data use reduced the availability of HFEA records after 2009. The fertility groups were derived by augmenting HFEA data with evidence from primary care records; however, there remains some potential misclassification of exposure groups. The cost of neonatal critical care is not captured in the HES APC data, which may cause underestimation of the cost differences between the comparison group and the infertility groups. The findings can help anticipate the financial impact on the healthcare system associated with subfertility and ART, particularly as the demand for these treatments grows.

Measuring growth in critically ill neonates and children.

Critical illness increases the risk of malnutrition in both infants and children. Malnutrition risk is multifactorial and includes premorbid factors as well as changes in nutrient metabolism and energy demands during critical illness. Inadequate nutrition has been linked to poor health outcomes and prolonged length of stay in the intensive care unit, demonstrating the importance of both recognizing and addressing malnutrition in this population. Assessing growth and identifying malnutrition requires methodical measurement of growth and a collaborative, multimodal approach to nutrition assessment. Among the nutrition assessment and growth evaluation tools, neonatal, preterm, pediatric, and disease-specific growth charts remain an important component of growth assessment and should be used along with a nutrition-focused physical examination. Routine measurement promotes the identification of potential growth delays that may require interventions. Indirect calorimetry adds an additional layer of detail for a complete picture of each infant or child's unique nutrition status and progress. Quality improvement research on a national level is urgently needed to assess the adequacy and availability of resources in neonatal and pediatric critical care units and to further the development of standard clinical outcome measures for nutrition assessment and intervention in the critically ill neonate and child.

Neonatal airway management training using simulation-based educational methods and technology

Airway management is a fundamental component of neonatal critical care and requires a high level of skill. Neonatal endotracheal intubation (ETI), bag-mask ventilation, and supraglottic airway management are complex technical skills to acquire and continually maintain. Simulation training has emerged as a leading educational modality to accelerate the acquisition of airway management skills and train interprofessional teams. However, current simulation-based training does not always replicate neonatal airway management needed for patient care with a high level of fidelity. Educators still rely on clinical training on live patients. In this article, we will a) review the importance of simulation-based neonatal airway training for learners and clinicians, b) evaluate the available training modalities, instructional design, and challenges for airway procedural skill acquisition, especially neonatal ETI, and c) describe the human factors affecting the transfer of airway training skills into the clinical environment.

A Review of Methods and Applications for a Heart Rate Variability Analysis

Heart rate variability (HRV) has emerged as an essential non-invasive tool for understanding cardiac autonomic function over the last few decades. This can be attributed to the direct connection between the heart’s rhythm and the activity of the sympathetic and parasympathetic nervous systems. The cost-effectiveness and ease with which one may obtain HRV data also make it an exciting and potential clinical tool for evaluating and identifying various health impairments. This article comprehensively describes a range of signal decomposition techniques and time-series modeling methods recently used in HRV analyses apart from the conventional HRV generation and feature extraction methods. Various weight-based feature selection approaches and dimensionality reduction techniques are summarized to assess the relevance of each HRV feature vector. The popular machine learning-based HRV feature classification techniques are also described. Some notable clinical applications of HRV analyses, like the detection of diabetes, sleep apnea, myocardial infarction, cardiac arrhythmia, hypertension, renal failure, psychiatric disorders, ANS Activity of Patients Undergoing Weaning from Mechanical Ventilation, and monitoring of fetal distress and neonatal critical care, are discussed. The latest research on the effect of external stimuli (like consuming alcohol) on autonomic nervous system (ANS) activity using HRV analyses is also summarized. The HRV analysis approaches summarized in our article can help future researchers to dive deep into their potential diagnostic applications.

Intestinal Obstruction by Meconium Ileus in the Newborn Revealing Cystic Fibrosis

Objective: To report a case of a preterm infant with meconium ileus at birth and cystic fibrosis. Background: The meconium ileus corresponds to the obstruction of the terminal ileum by an abnormally thick meconium; it is observed most often in neonates with cystic fibrosis. Case description: a female infant was born by cesarean delivery section on severe pre-eclampsia with oligohydramnios and intrauterine growth restriction, weighing 1230 g at 36 weeks of gestational age, with Apgar scores of 10/10. His mother was a 26-year-old G2P2 who had attended three prenatal consultations with negative serology for vertical infections. Immediately after birth, the newborn was referred to our neonatal critical care unit due to severe abdominal distension. the Newborn had a delay in meconium emission of more than 48 hours. an abdominal X-ray showed significant intestinal distension and a barium enema was performed showing meconium plugs with a colon of normal topography and caliber, initially put on antibiotic therapy with enema by gastroraphy twice a day, an etiological assessment was carried: A genetic study was conducted, revealing that the newborn is a carrier of a variant (c.1521-1523delCTT,p.Phe508del F50 del) associated with a classic form of cystic fibrosis in a homozygous state and the first immunoreactive trypsinogen (IRT) was &gt; 1300 ug/l (reference value &gt;1000 ug/l), in view of the non-improvement the newborn benefited from an ileostomy. Comments: This case illustrates the rapid evolution of CF in a premature patient with meconium ileus as the first clinical manifestation.
