Abstract Objective The aim of this narrative review is to highlight the association of ineffective feeding practices with the development of malocclusion in children and the role of a pediatric dentist in identifying the cues and signs of improper feeds, and encourage effective breastfeeding practices. Introduction There has been an ongoing debate on the role of effective breastfeeding in the prevention of malocclusion. Although no specific claim supports the positive impact of the same, a detailed reviewing of the literature helps to identify the method of feeding to be chosen considering health benefits and personal preference. Materials and Methods A broad search of all resources linked to the topic was performed in PubMed, Medline, World Health Organization web site, government web sites, and Google Scholar search engine. Keywords used in the search included breastfeeding, ineffective breastfeeding, bottle feeding, pacifier, and malocclusion. A total of 60 articles published in the period from 2000 to 2019 were segregated. Selected articles comprised original research, meta-analysis, and systematic reviews. Results Parameters such as duration, posture, and non-nutritive sucking habits had an impact on effective breastfeeding. Discussion Effective breastfeeding and maintaining appropriate posture and duration helps to positively impact the normal growth and development of the jaws, muscular functioning, and speech. Thereby, the risk of developing malocclusion in primary dentition can be prevented. Conclusion An understanding of the role of breastfeeding and malocclusion will help in the early intervention and prevention of malocclusion and deviated muscular function. Highlighting the role of counseling and effective feeding practices is also an area that should be focused upon by budding clinicians.

Prematurely Born Infants

The N3 and N6 long chain polyunsaturated fatty acids (LCPUFA) docosahexaenoic acid (DHA) and arachidonic acid (AA) are essential for proper neurodevelopment in early life. These fatty acids are passed from mother to infant via the placenta, accreting into fetal tissues such as brain and adipose tissue. Placental transfer of LCPUFA is highest in the final trimester, but this transfer is abruptly severed with premature birth. As such, efforts have been made to supplement the post-natal feed of premature infants with LCPUFA to improve neurodevelopmental outcomes. This narrative review analyzes the current body of evidence pertinent to neurodevelopmental outcomes after LCPUFA supplementation in prematurely born infants, which was identified via the reference lists of systematic and narrative reviews and PubMed search engine results. This review finds that, while the evidence is weakened by heterogeneity, it may be seen that feed comprising 0.3% DHA and 0.6% AA is associated with more positive neurodevelopmental outcomes than LCPUFA-deplete feed. While no new RCTs have been performed since the most recent Cochrane meta-analysis in 2016, this narrative review provides a wider commentary; the wider effects of LCPUFA supplementation in prematurely born infants, the physiology of LCPUFA accretion into preterm tissues, and the physiological effects of LCPUFA that affect neurodevelopment. We also discuss the roles of maternal LCPUFA status as a modifiable factor affecting the risk of preterm birth and infant neurodevelopmental outcomes. To better understand the role of LCPUFAs in infant neurodevelopment, future study designs must consider absolute and relative availabilities of all LCPUFA species and incorporate the LCPUFA status of both mother and infant in pre- and postnatal periods.

Critical Patients

Background: Coronavirus disease (COVID-19), once identified, soon spread globally, becoming a pandemic. Although patients present mainly with respiratory complaints, several neurological symptoms have been reported. Symptoms range from headache and nonspecific dizziness to seizures and cerebrovascular disease (CVD). It has also been shown that the severity of the infection is directly proportional to the development of neurological symptoms, especially CVD and changes in mental status. Objective: The present study aims to briefly review the neurological manifestations of COVID-19 and discuss the pathogenic mechanisms of Central Nervous System (CNS) involvement. Methods: This is an exploratory narrative review with a descriptive approach, consisting of an active search for scientific articles in the PubMed database. The descriptors “coronavirus infections”, “COVID-19” and “Nervous system” were used, with the Boolean operators “OR” and “AND”. Eighteen articles of systematic review and meta-analysis were included. Results: CNS manifestations included, among others: encephalitis, encephalopathy, consciousness decrease, headache, dizziness, acute myelitis, and stroke. As for the peripheral nervous system, skeletal muscle damage, chemosensory dysfunction, and Guillain-Barré syndrome were observed, with hyposmia being the most common symptom. CNS involvement may be related to a worse prognosis. Conclusion: The clinical involvement of the nervous system in COVID-19 is not uncommon, and can result in several neurological complications, especially in the most critical patients. The pathophysiological mechanisms of these events still need further investigation. In the meantime, physicians should value extra-respiratory symptoms ranging from hyposmia, to potentially fatal manifestations, such as stroke and encephalopathy.

Service Interaction

Purpose – This paper aims to conceptualize and empirically test the determinants of service interaction quality (SIQ) as attitude, behavior and expertise of a service provider (SP). Further, the individual and simultaneous effects of SIQ and its dimensions on important marketing outcomes are tested. Design/methodology/approach – The narrative review of extant research helps formulate a conceptual model of SIQ, which is investigated using the univariate and multivariate meta-analysis. Findings – There are interdependencies between drivers of SIQ that underlines the need to conceptualize service interaction as a dyadic phenomenon; use contemporary multilevel models, dyadic models, non-linear structural equation modeling and process studies; and study new and diverse services contexts. Meta-analysis illustrates the relative importance of the three drivers of SIQ and, in turn, their impact on consumer satisfaction and loyalty. Research limitations/implications – The meta-analysis is based on existing research, which, unfortunately, has not examined critical services or exigency situations where SIQ is of paramount importance. Future research will be tasked with diversifying to several important domains where SIQ is a critical aspect of perceived service quality. Practical implications – This study emphasizes that, although the expertise of an SP is important, firms would be surprised to learn that the attitude and behavior of their employees are equally important antecedents. In fact, there is a delicate balance that needs to be found; otherwise, attitudinal factors can have an overall counterproductive effect on consumer satisfaction. Originality/value – This paper provides an empirical synthesis of SIQ and opens up interesting areas for further research.
