Do not do recommendations in different paediatric care settings

INTRODUCTION

There are many initiatives aimed at eliminating health care interventions of limited utility in clinical practice. The Committee on Care Quality and Patient Safety of the Spanish Association of Pediatrics (AEP) has proposed the development of "DO NOT DO" recommendations (DNDRs) to establish a series of practices to be avoided in the care of paediatric patients in primary, emergency, inpatient and home-based care.

MATERIAL AND METHODS

The project was carried out in 2 phases: a first phase in which possible DNDRs were proposed, and a second in which the final recommendations were established by consensus using the Delphi method. Recommendations were proposed and evaluated by members of the professional groups and paediatrics societies invited to participate in the project under the coordination of members of the Committee on Care Quality and Patient Safety.

RESULTS

A total of 164 DNDRs were proposed by the Spanish Society of Neonatology, the Spanish Association of Primary Care Paediatrics, the Spanish Society of Paediatric Emergency Medicine, the Spanish Society of Internal Hospital Paediatrics and the Medicines Committee of the AEP and the Spanish Group of Paediatric Pharmacy of the Spanish Society of Hospital Pharmacy. The initial set was limited to 42 DNDRs, and the selection over successive rounds yielded a final set of 25 DNDRs, with 5 DNDRs for each paediatrics group or society.

CONCLUSIONS

This project allowed the selection and establishment by consensus of a series of recommendations to avoid unsafe, inefficient or low-value practices in different areas of paediatric care, which may contribute to improving the safety and quality of paediatric clinical practice.

Material and sedation-analgesia in the neonatal lumbar puncture procedure

INTRODUCTION

Lumbar puncture (LP) is a frequent procedure during the neonatal period. Correctly performing this technique can avoid many of its complications.

OBJECTIVE

To evaluate the LP procedure in neonates in Spanish hospitals, studying the type of material and the sedation-analgesia used.

MATERIAL AND METHODS

Cross-sectional study conducted in Spain gathering data through a survey research distributed by email through the Segurneo-SEN Hospital Network and the Spanish Neonatal Society. Data on the LP technique in neonates were collected.

RESULTS

A total of 301 participants were analysed. Most professionals used a trocar needle with a stylet as the first option (89.7%); however, when the LP failed or was blood-stained, 32.2% changed the type of needle. A total of 143 doctors gave their subjective feeling about the type of needle: they only use trocar needles with stylet (41.3%), the technique is easier using scalp-vein needles (32.2%), there is less probability of a blood-stained LP, or failed using scalp-vein needles (7.7%), they choose the type of needle depending on the size of the newborn (10.5%), indifference when using one type or another needle (8.4%). Almost all (99%) of the surveyed doctors used some type of analgesia. The most widely used measures were topical anaesthetics (90.3%) and sucrose (82.2%).

CONCLUSIONS

Currently, the LP procedure in the neonatal period is mainly performed with a trocar needle with a stylet and with the widespread use of different analgesic measures.

Neonatal Infection Due to SARS-CoV-2: An Epidemiological Study in Spain

Objective: Coronavirus disease 2019 (COVID-19) cases caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continue to increase worldwide. Although some data from pediatric series are available, more evidence is required, especially in neonates, a group with specific characteristics that deserve special attention. This study aimed to describe general and clinical characteristics, management, and treatment of postnatal-acquired (community and nosocomial/hospital-acquired) COVID-19 neonatal cases in Spain. Methods: This was a national prospective epidemiological study that included cases from a National Registry supported by the Spanish Society of Neonatology. Neonates with postnatal SARS-CoV-2 infection were included in this study. General data and infection-related information (mode and source of transmission, age at diagnosis, clinical manifestations, need for hospitalization, admission unit, treatment administered, and complementary studies performed, hospital stay associated with the infection) were collected. Results: A total of 40 cases, 26 community-acquired and 14 nosocomial were registered. Ten were preterm newborns (2 community-acquired and 8 nosocomial COVID-19 cases). Mothers (in both groups) and healthcare workers (in nosocomial cases) were the main source of infection. Hospital admission was required in 22 community-acquired cases [18 admitted to the neonatal intermediate care unit (NIMCU) and 4 to the neonatal intensive care unit (NICU)]. Among nosocomial COVID-19 cases (n = 14), previously admitted for other reasons, 4 were admitted to the NIMCU and 10 to the NICU. Ten asymptomatic patients were registered (5 in each group). In the remaining cases, clinical manifestations were generally mild in both groups, including upper respiratory airways infection, febrile syndrome or acute gastroenteritis with good overall health. In both groups, most severe cases occurred in preterm neonates or neonates with concomitant pathologies. Most of the cases did not require respiratory support. Hydroxychloroquine was administered to 4 patients in the community-acquired group and to 2 patients in the nosocomial group. Follow-up after hospital discharge was performed in most patients. Conclusions: This is the largest series of COVID-19 neonatal cases in Spain published to date. Although clinical manifestations were generally mild, prevention, treatment, and management in this group are essential.

[Risk factors for the development of early hyponatraemia in the premature infant. A review of the practice of giving sodium in the first days of life]

INTRODUCTION

A retrospective study was conducted in the Neonatal Intensive Care Unit of a tertiary hospital to determine the incidence of early hyponatraemia (first 48hours of life) in preterm infants. Risk and protection factors in this condition were also examined as a starting point for a change in the medical action when prescribing intravenous fluids.

MATERIAL AND METHODS

The study included a sample of 256 premature babies (gestational age: 23⁵-36⁶) admitted to the Neonatal Intensive Care Unit of a tertiary hospital between January 2016 and June 2018. The number of patients receiving intravenous sodium in different intervals during the first 48hours of life was determined, as well as the number of those with hyponatraemia of any type (<135mmol / l), and moderate-severe (<130mmol / l). An analysis was made of the relationship between early hyponatraemia and weight / gestational age, antenatal steroids exposure, respiratory pathology, early sepsis, and perinatal asphyxia.

RESULTS

Hyponatraemia occurred in 81 patients, 31.64% of the total (up to 50% in<30 weeks of gestational age), and was moderate-severe (<130mmol / l) in 17.3% of the cases. The period of time with the most cases of hyponatraemia was in the first 12hours of life (22.64%). Weight (P=.034), gestational age (P<.001) and respiratory disease (P<.001) were found to be risk factors and, in a multivariate analysis, the latter was independently related to early hyponatremia (P<.01, OR=5.24, 95% CI: 2.79-9.84). Antenatal betamethasone exposure did not show to be a protection factor.

CONCLUSION

According to the results of this study, it is considered an advantage to provide sodium in the intravenous fluids prescribed during the first days of life, particularly in preterm infants of lower gestational age and with respiratory disease involvement.

[Evaluation of a pharmaceutical care program to improve adherence to antiretroviral therapy]

OBJECTIVE

To establish the impact of a pharmaceutical care program on the improvement of adherence to antiretroviral therapy, and on patient immunologic and virologic outcome.

MATERIALS AND METHODS

A multicenter, observational, prospective study in a HIV-infected patient cohort under treatment with antiretrovirals selected by random sampling in 19 Spanish hospitals. The study lasted 12 months, in which the program was applied through a baseline preprocedural visit and 4 quarterly visits. Adherence estimation was based on pill counting. An adherence > or = 90, or > or = 95% was considered adequate (in two time points).

RESULTS

541 patients were included, most of them were males (68.8%) between 20 and 78 years of age. Major risk groups included injecting drug users (43.4%) and heterosexuals (29.4%). Sixty percent had already received treatment for more than 3 years. Mean baseline viral load and CD4 count values were 32,866 copies/ml and 485 cells/mm3, respectively. Throughout the study a slight increase in the percentage of adherent patients was seen; however, statistical significance was not reached (64.3 and 79.2% of patients showed an adherence > 95 and > 90%, respectively, during the fourth quarter, versus 59.8 and 75.5% at baseline). A statistically significant decrease in viral load and increase in CD4 cells was seen following program application. The percentage of patients with a viral load < 200 copies/ml was 72.2, 76.7, and 75.0% at the 2nd, 3rd, and 4th quarters, respectively, versus 64.2% at baseline. CD4 cell counts increased by 50 cells/mm3 on average from the start to the end of follow-up.

CONCLUSIONS

Patients included in the program had a good immunologic and virologic outcome, and a trend towards an increased percentage of patients with good adherence was also seen. These results confirm the need to implement follow-up programs for patients receiving antiretrovirals in order to ensure maximum therapeutic benefits.

Exposure assessment must stop being local

Exposure assessment activities today are hampered by a narrow focus that is detrimental to preventive occupational health goals. Exposure data useful for disease prevention are not adequately collected, and exposure surveillance tools do not receive adequate attention. Professional recommendations to improve this state of affairs have been in existence since the early 1990s, but have not been widely adopted. Although the Government Performance and Results Act could help address these shortcomings--by enhancing exposure surveillance activities in the OSHA and NIOSH Strategic Plans--the agencies have not taken advantage of this opportunity. Their strategic plans rely largely on accident data to measure performance, despite the fact that occupational disease has a much larger toll. This article makes recommendations to address these shortcomings by increasing the role of exposure surveillance tools in the agency strategic plans.

Factors associated with exposure in Occupational Safety and Health Administration data

This study investigated the possibility of making compliance data from the public and private sectors more amenable for multiple uses, by studying data from Occupational Safety and Health Administration (OSHA) inspections during 1979-1989. The potential association of five variables with mean and upper-end (in upper quartile) airborne exposures in similar exposure groups was investigated. The exposure groups reflected airborne exposures to lead in the battery manufacturing industry, to perchloroethylene among dry cleaners, and to iron oxide among welders in three metal fabrication industries. Variables examined were year, inspection type and scope, and size and union status of inspected establishments. Multiple linear regression and logistic regression models were used for the analyses. In small battery plants mean exposure levels were higher and the relative frequency of upper-end exposures (> 75th percentile) greater than in larger establishments. Evidence suggested a decline in mean lead exposures (5-9% per year). Neither type of inspection nor union status were associated with mean or upper-end levels of lead exposure, although the study's power to detect an association was sometimes modest. Some evidence showed that full scope inspections may be associated with higher mean exposures. Strong evidence showed a decline in mean perchloroethylene exposures among dry cleaners (7% per year), but no temporal trends for welder exposures to iron oxide. With few exceptions, the size, type, scope, and union variables were rarely associated with mean or upper-end exposure levels among dry cleaners or welders, although the power of the analyses to detect associations was at times modest. Results show that OSHA data is amenable to analysis that can provide valuable insights about workplace exposures. Several findings of the study are directly useful to the design of public policy.

[Experimental and pathological models that explain the regulation of cellular migration and axon's orientations]

Since Cajal discovery of nerve growth cones and their role in the growth, metabolism and destination of the axon in 1890 numerous studies have corroborated with more sophisticated techniques his original findings and ideas. The use of modified Golgi staining, drawing from the camera lucida in 2 combination with electron microscopy and t retrograde biochemical markers have helped to identify the neuronal sites of synapsis. Dynamic studies of the nerve growth cones using time-lapsed video microscopic images of living neuroblast in t culture or the intact animal have demonstrated their protactil and retractile membranes and exploratory filipodia properties. Interaction between growth cone membrane receptors and different molecules along the migrating axon determine also its final destination. Finally the role that genes play on neuronal migration and in guiding the axons to reach their targets have been identified in patients with Kallmann syndrome, a migrational disorder of olfactory axons and hypothalamic gonadotropic hormone-releasing hormone with absent gene at Xp22.3 locus manifested by anosmia and hypogonadotropic hypogonadism.

The possible value of ascorbic acid as a prophylactic agent for urinary tract infection

The effect of ascorbic acid on urine pH was studied in spinal cord injury patients. Their urine was not colonized by urease positive microorganisms. The study was designed to compare the baseline urine pH value and the urine pH value after the administration of placebo or ascorbic acid 500 mg/6 h. The diet and medical treatment were not controlled. A significant decrease in urine pH value was not obtained. There was no clinical benefit from the use of ascorbic acid.

History of the tuberous sclerosis complex

How the concept of the tuberous sclerosis complex (TSC) has developed over a period of time spanning 160 years has come form simple clinical observations, pathological studies and technological advances of imaging methods. It all began with PFO Rayer's color plate of a drawing of a patient who apparently had facial angiofibroma, published in the year 1835, and continued with von Recklinghausen's report of cardiac myomas and cerebral sclerosis in a newborn who had died minutes after birth. The seminal contribution was provided by D.M. Bourneville who, in 1880, reported and named as tuberous sclerosis the neuropathological findings in a young patient with seizures, hemiplegia, and mental subnormality who also had renal tumors. We now know that TSC is a hamartomatosis, and thanks to studies of recent years using positional cloning and DNA analysis, we are beginning to understand the biological mechanisms of these disorders which include NF1, NF2 and von Hippel-Lindau disease. Unique to TSC is that it is both phenotypically and genotypically heterogeneous. One of two suspected genes found in chromosome 16 by positional cloning has been cloned (TSC2). Another one that was discovered earlier in chromosome 9 (TSC1) has not yet been characterized. The gene product from TSC2 has been named tuberin.

Occupational exposure to chlorinated aliphatic hydrocarbons and risk of astrocytic brain cancer

Chlorinated aliphatic hydrocarbons (CAHs) were evaluated as potential risk factors for astrocytic brain tumors. Job-exposure matrices for six individual CAHs and for the general class of organic solvents were applied to data from a case-control study of brain cancer among white men. The matrices indicated whether the CAHs were likely to have been used in each industry and occupation by decade (1920-1980), and provided estimates of probability and intensity of exposure for "exposed" industries and occupations. Cumulative exposure indices were calculated for each subject. Associations of astrocytic brain cancer were observed with likely exposure to carbon tetrachloride, methylene chloride, tetrachloroethylene, and trichloroethylene, but were strongest for methylene chloride. Exposure to chloroform or methyl chloroform showed little indication of an association with brain cancer. Risk of astrocytic brain tumors increased with probability and average intensity of exposure, and with duration of employment in jobs considered exposed to methylene chloride, but not with a cumulative exposure score. These trends could not be explained by exposures to the other solvents.
