RESUMO

PURPOSE: Nisin is a lantibiotic effective against Gram-positive microorganisms such as Streptococcus mutans. The study aimed to determine the effect of the addition of nisin to high-viscosity glass-ionomer cement (HVGIC) on its antibacterial activity, setting time, surface microhardness, and compressive strength. METHODS: 1 and 3% w/w nisin were added to HVGIC before mixing. Unmodified HVGIC was the control. Agar disc diffusion, direct contact test, and scanning electron microscopy (SEM) analysis were used to evaluate antibacterial activity against S. mutans. Setting time, surface microhardness, and compressive strength were measured using Gilmore needle apparatus, digital microhardness tester, and universal testing machine, respectively. Statistical analysis included Student's t test, one-way ANOVA with Tamhane's post hoc test, and repeated-measures ANOVA. RESULTS: As evidenced by the agar disc diffusion (p < 0.001), direct contact tests (p = 0.025), and SEM analysis of the S. mutans cell count and cell surface area (p = 0.049 and 0.003), 3% nisin had the strongest antibacterial activity. There was a dose-dependent increase in setting time (p = 0.005) and surface microhardness (p = 0.006), with no significant difference in compressive strength compared to control. CONCLUSION: The addition of 3% nisin to HVGIC enhances the antibacterial action against S. mutans and surface microhardness without adversely affecting setting time and compressive strength.

RESUMO

BACKGROUND: Parents often underuse dental care services for their children with early childhood caries (ECC), resulting in a high burden of untreated dental caries. AIM: To describe parental perceptions and challenges in dental care utilization for their children with ECC. DESIGN: A descriptive qualitative study was conducted with parents of children with ECC seeking dental care in Mangalore, India. Data were collected through focus group discussions using an interview guide. Manual line-by-line coding and content analysis methods were used for data analysis. RESULTS: Three categories were generated from data obtained through 5 focus groups of 27 participants: dental care visiting patterns, the significance of dental visits, and challenges to dental care utilization. Parents would only visit the dentist when they perceived their children's tooth problems. The challenges faced include time constraints, misinformation, lack of awareness and motivation, costs, fear, and anxiety of the children and the parents themselves. Parents perceived improvements in the awareness of their children's oral health and quality of life after dental visits. CONCLUSION: Attending dental services to treat their children's tooth problems was the primary way of attaining awareness about prevention among the parents of children with ECC. Increased oral health awareness and improved quality of life can motivate parents to seek further dental care for their children. Collaboration with multidisciplinary stakeholders is required to improve oral health awareness among parents of children with ECC. KNOWLEDGE TRANSFER STATEMENT: The study's results will help plan targeted preventive programs for children with ECC. The study suggests dental care utilization by children with ECC is based on parental perceptions of their children's tooth problems. It outlines the challenges that affect dental visits of children with ECC and the role of multidisciplinary stakeholders. Improved oral health awareness and quality of life following dental treatment can facilitate further dental visits.

RESUMO

PURPOSE: To evaluate and compare the clinical effectiveness of alkasite with nanofilled resin composite restorations for occlusal caries lesions in permanent molar teeth of children, at one-year follow-up. METHODS: In this randomized controlled clinical trial with parallel design, 38 children aged 7-13 years with occlusal caries lesions on 59 first permanent molars were randomly allocated into two groups, Group 1: Filtek™ Z350XT (nanocomposite) and Group 2: Cention N® (alkasite resin composite). The restorations were evaluated at one year using the United States Public Health Service (USPHS) criteria. Data were analyzed using Chi-square or Fisher's exact test. RESULTS: All restorations had either Alpha or Bravo scores at one-year follow-up. In Group 1, all restorations scored Alpha, while one restoration each (3.6%) in Group 2 scored Bravo for fracture and marginal adaptation. All restorations in both groups scored Alpha for retention, secondary caries, and post-operative sensitivity. For anatomic form, all restorations in Group 1 scored Alpha, while three (10.7%) restorations in Group 2 had Bravo scores. For marginal discolouration, three restorations in both groups scored Bravo (11.5% and 10.7%, respectively). For surface roughness, one restoration (3.8%) in Group 1 and three restorations in Group 2 (10.7%) scored Bravo. The comparative results between the two groups for all the variables in the USPHS criteria were not statistically significantly different. CONCLUSIONS: The performances of the nanofilled composite and alkasite were clinically acceptable and comparable. Alkasite can be an alternative material for the restoration of occlusal caries lesions in permanent molars of children. CLINICAL TRIAL REGISTRATION: The clinical trial was registered at Clinical Trials Registry-India (CTRI Reg no: CTRI/2020/12/029830 Dated: 15/12/2020).

RESUMO

In the present double-blind randomised study, the efficacy of combination of Bacillus coagulans Unique IS2 and lactulose was evaluated in the treatment of functional constipation in adults. One-fifty participants diagnosed with functional constipation (Rome III criteria) were randomised (1:1:1) and supplemented daily with 15 mL suspension of probiotic (B. coagulans Unique IS2, 2 × 109 spores) with lactulose (10 g) (group 1) or lactulose (10 g) (group 2) or placebo (water) (group 3) for 4 weeks. The primary (stool frequency) and secondary outome measures (stool consistency, sensation of incomplete evacuation, defecation- and abdominal-pain) were recorded weekly for up to 4 weeks. Bacillus coagulans Unique IS2 with lactulose showed significant changes in stool frequency as compared to lactulose treatment; however, at the end of the trial, it was found insignificant due to the gradual increase of stool frequency score of lactulose treatment. The changes observed in stool consistency were early (2nd week) and remained consistent up to end of the trial. The significant reduction of sensation of incomplete evacuation, defecation-, and abdominal-pain correlated with the strains ability to produce short-chain fatty acids. No adverse events were observed in any of the groups, and all the vital parameters were normal during the course of the study. Overall, results indicated that B. coagulans Unique IS2 addition to lactulose reduced time required to relieve constipation as compared to lactulose alone. In conclusion, B. coagulans Unique IS2 with lactulose is more effective than lactulose alone to relieve symptoms of constipation in a shorter period. Trial registration: CTRI/2018/11/016399, dated 22/11/2018.

RESUMO

OBJECTIVE: To describe the early feeding, weaning, and oral hygiene practices of children with early childhood caries (ECC), their parents' knowledge and attitudes regarding infant feeding, and the feeding-related challenges faced by the parents. METHODS: This descriptive qualitative study involved parents of children with ECC who sought dental treatment at an academic dental college in India. Data were collected though focus groups conducted with the 27 parents of children with ECC, using a focus group discussion guide. Data were analyzed using the content analysis method. RESULTS: Community norms, such as learning from the older women in the families or neighborhoods, guided the feeding method, duration of feeding, and weaning. Breastfeeding or bottle-feeding at bedtime beyond 12 mo of age and feeding sugary drinks during weaning were standard practices, despite knowing the risk for dental caries. Parents faced multiple challenges regarding weaning and were unaware of the significance of infant oral hygiene practices. CONCLUSION: In children with ECC, infant feeding practices included prolonged breastfeeding or bottle-feeding beyond the required age, feeding at bedtime, and feeding sugary drinks. Although the parents knew that these feeding habits could increase the risk for caries, they lacked the self-efficacy to translate their knowledge into action during weaning. Also, they lacked awareness regarding infant oral hygiene practices. KNOWLEDGE TRANSFER STATEMENT: The study provides information on the feeding habits of infants that can increase the risk for caries, the challenges faced by the parents of these children in altering these risky habits, and their lack of knowledge on infant oral hygiene practices. Policy/decision makers can advocate for pediatricians and pediatric dentists to incorporate anticipatory guidance or motivational interviewing techniques to tailor the preventive program for ECC for Indian children.

RESUMO

Introduction: Clavicle fractures are frequently encountered by orthopaedic surgeons. Though multiple treatment techniques have been described in literature, open reduction and internal fixation with plating and intramedullary nailing are preferred in adults. This study analyses the functional outcome, complications, duration of bony union of mid-shaft clavicle fractures treated with plate fixation versus intramedullary fixation. Materials and methods: A quasi-experimental study was conducted on 38 patients with mid-shaft clavicle fracture aged between 18 to 60 years at a tertiary care centre in South India. Nineteen patients were treated by plate fixation and 19 patients underwent intramedullary nail fixation. Every alternate patient with mid-shaft fracture clavicle was treated with plate osteosyntheses or nailing. Results: The average age of presentation was 42 years in plate fixation and 31 years in nail fixation group. Robinson's classification type 2B1 was the most common type of fracture in both groups. The Visual Analogue Scale (VAS) score reduced significantly from pre-operative to postoperative day 1 in both the groups but there was no significant difference between the two groups. The Disabilities of the Arm, Shoulder and Hand (DASH) score at 6, 12 and 24 weeks reduced significantly in both the groups but showed no statistically significant difference between the two groups. However, intramedullary nail fixation group had a shorter duration of hospital stay and showed an earlier improvement in the DASH score during the first six months after surgery. Complications included implant loosening (three patients) in plating group and implant failures (two cases) in nailing group. Conclusion: There is a role for surgical intervention for certain cases of displaced and comminuted clavicle fracture in order to avoid malunion or non-union and their potential long-term sequelae. Both the surgical modalities of plating, and nailing provide good functional outcome and allow early return to occupational activities.

RESUMO

PURPOSE: The aim of the study was to compare the effect of a stress ball, an active distraction technique with audio-visual eyeglasses, a passive distraction technique during local anaesthesia administration, on dental anxiety (primary outcome), behaviour and pain levels of children (secondary outcomes). METHODS: In this randomised controlled parallel arm trial involving 123 children aged 8-12 years, who required dental treatment under inferior alveolar nerve block, children were randomly allocated into the following three groups: Group 1: Stress ball, Group 2: Audio-visual eyeglasses, Group 3: Control group (basic behaviour guidance without distraction). Dental anxiety was measured using modified child dental anxiety scale and pulse rate, behaviour was rated using Venham's scale and pain was measured by both self-reporting and observational scales. RESULTS: No significant difference between the groups was observed for dental anxiety, but a significant decrease was seen in dental anxiety scores within all groups. No significant differences were seen between the groups for behaviour ratings and pain scores. CONCLUSION: Use of active stress ball distraction or passive audio-visual eyeglasses during local anaesthesia administration decreased dental anxiety but did not result in a significant improvement in the dental anxiety, behaviour and pain levels when compared to basic behaviour guidance without distraction. CLINICAL TRIAL REGISTRATION: The clinical trial was registered at Clinical Trials Registry-India (CTRI Reg no: CTRI/2019/04/018768, Dated 24 April 2019).

RESUMO

INTRODUCTION: The risk of fracture from a non-accidental injury is highest in the infant age group. A spiral fracture of the long bone can occur equally from accidental and non-accidental causes, meaning the clinical judgement of non-accidental injury in an infant is particularly challenging. This study aimed to assist in differentiating accidental, from non-accidental, injury in infants, by establishing whether correlation exists between geometry and torsional strength in the immature long bone. METHODS: Immature porcine third and fourth metacarpals (n = 21) were imaged with a dual energy x-ray absorptiometry (DEXA) scanner to measure their linear bone mineral content (BMCL), bone mineral density (BMD) and section modulus (Z). The specimens were then subjected to a torque of one degree per second until failure. The failure strength and the three DEXA measures were analyzed for a correlation. RESULTS: The mean failure strength of 11 successful tests was 13.71Nm (+/-SD 2.42Nm), with correlation to BMCL, BMD and Z described by r2 = 0.81, 0.283 and 0.75 respectively. CONCLUSION: This study is a novel attempt at estimating torsional strength of long bones in a specific paediatric age group using a size-matched animal bone model. It found a strong correlation between bone and fracture strength parameters over the BMCL range of 0.59-0.77 g/cm.

RESUMO

The location and/or type of variants in FLNB result in a spectrum of osteochondrodysplasias ranging from mild forms, like spondylocarpotarsal synostosis syndrome and Larsen syndrome, to severe perinatal lethal forms, such as atelosteogenesis I and III and Boomerang dysplasia. Spondylocarpotarsal synostosis syndrome is characterized by disproportionate short stature, vertebral anomalies and fusion of carpal and tarsal bones. Biallelic loss-of-function variants in FLNB are known to cause spondylocarpotarsal synostosis syndrome and 9 families and 9 pathogenic variants have been reported so far. We report clinical features of 10 additional patients from 7 families with spondylocarpotarsal synostosis syndrome due to 7 novel deleterious variants in FLNB, thus expanding the clinical and molecular repertoire of spondylocarpotarsal synostosis syndrome. Our report validates key clinical (fused thoracic vertebrae and carpal and tarsal coalition) and molecular (truncating variants in FLNB) characteristics of this condition.

RESUMO

We set out to evaluate multiplex ligation dependent probe amplification (MLPA) as a tool for diagnosis and carrier detection in families with a dystrophinopathy. Fifty three Indian families with provisional diagnosis of Duchene muscular dystrophy or Becker muscular dystrophy were evaluated by MLPA and multiplex polymerase chain reaction (PCR). Sanger sequencing was used to analyze the entire gene in one patient. Mothers were tested for carrier status whenever possible. Molecular analysis of DMD gene by combining MLPA and multiplex PCR yielded a mutation detection rate of 62% (33/53). Deletions were detected in 27/53 (51%) cases, duplications in 5/53 (9%) cases, a small deletion one case and Sanger sequencing detected a nonsense mutation in one case. Mutation was not detected in 36% (19/53) cases. Fifty six percent of mothers (9/16) were found to be carriers. MLPA helped to refine the results of multiplex PCR testing in 22 patients (5 duplications, 16 deletions and one small deletion). We also describe a situation where a deletion of single exon on MLPA (but not detected by multiplex PCR) was actually due to a deletion of two nucleotides in the probe ligation site. MLPA appears to score over multiplex PCR in diagnosis and carrier detection, specifically by detecting deletions and duplications that are not detected by traditional multiplex PCR.

RESUMO

OBJECTIVE: To enumerate the fluoride content and labelling practices of toothpastes marketed in India and to determine if the content is in accordance with the information provided on the packaging. METHOD: In vitro analysis of total and free available fluoride in 5 adult and 5 children's fluoride toothpastes in India using fluoride ion electrode. Information on the tube and carton was checked to assess the labelling. RESULTS: The mean Total Fluoride concentrations (TF) in the toothpastes labelled 1,000 ppm, 500ppm and 458 ppm were 1,000, 500 and 449mg/L (sd values 3, 5 and 4mg/L) respectively. The toothpastes' Total Soluble Fluoride (TSF) concentration was generally slightly less than the TF concentration. Overall mean percentage of TSF concentration was 94% sd 9%. The mean percentage of TSF concentration in SMFP (sodium monofluorophosphate)/CaCO3 (calcium carbonate) containing toothpastes was 86% sd 16% while that in NaF (sodium fluoride)/Si (silica) based toothpastes was 98% sd 1% and 95% sd 1% in the remaining toothpastes with unknown abrasive. NaF/Si based toothpastes had more TSF concentration than the others (p<0.05). All the information required by the Indian regulations was shown on all 10 toothpastes. CONCLUSION: The available fluoride content of one of the ten toothpastes was substantially less than the total fluoride content. Although the toothpastes were labelled following the guidelines of the regulatory body of India, 3 of the 10 failed to mention the abrasive present.

RESUMO

Carpometacarpal (CMC) joint dislocations are uncommon injuries that account for less than 1% of hand injuries. Dorsal dislocations of the CMC joints are more frequent than volar dislocations. Palmar dislocations can be either ulnopalmar or radiopalmar. There are very few reports of isolated radiopalmar dislocations of the fifth CMC joint in the English-language literature. In our case of radiopalmar dislocation, diagnosis was delayed, and attempts at closed reduction were unsuccessful. Therefore, it was treated by open reduction and Kirschner-wire fixation. This article reports a rare type of injury and discusses its management.

RESUMO

The diagnosis and treatment of tuberculosis (TB) in people who use and/or inject illicit drugs (PWUIDs) remains a barrier to achieving universal coverage for TB in India and globally. This report describes treatment outcomes in PWUIDs who received treatment for drug-susceptible TB at the Mon District Hospital in Nagaland, India, during 2012-2013. The median age of the patients was 39 years, and most (92%) were male. Two thirds (33/49) of the patients had a successful TB treatment outcome. A previous TB episode and residence in a semi-urban area were associated with unsuccessful treatment outcomes. Separate diagnostic and treatment algorithms, including regular adherence counselling and opioid substitution therapies, should be considered for PWUIDs.


Le diagnostic et le traitement de la tuberculose (TB) chez les personnes qui consomment et/ou s'injectent des drogues (PWUID) constitue encore un obstacle à l'atteinte d'une couverture universelle de la TB en Inde et dans le monde. Ce rapport décrit les résultats du traitement de PWUID qui ont bénéficié d'un traitement de TB pharmacosensible à l'hôpital Mon District de Nagaland, Inde, en 2012­2013. L'âge médian des patients a été de 39 ans et la majorité (92%) étaient des hommes. Les deux tiers (33/49) des patients ont eu un bon résultat thérapeutique. L'existence d'un épisode préalable de TB et le fait de résider en zone semi-urbaine ont été associés à un échec thérapeutique. Des algorithmes séparés de diagnostic et de traitement, incluant des séances régulières de conseil pour l'observance et des traitements de substitution aux opiacés, devraient être envisagées pour les PWUID.


El diagnóstico y el tratamiento de la tuberculosis (TB) en las personas que consumen o se inyectan drogas (PWUID) siguen creando obstáculos al cumplimiento de la cobertura universal de la TB en la India y en el mundo. En el presente informe se describe el desenlace terapéutico en personas de este grupo que recibieron un tratamiento por TB normosensible en el hospital Mon District de Nagaland, en la India, del 2012 al 2013. La mediana de la edad de los pacientes fue 39 años y la mayoría (92%) era de sexo masculino. Dos tercios de los pacientes (33 de 49) alcanzaron un desenlace favorable del tratamiento antituberculoso. Se asociaron con los desenlaces desfavorables el antecedente de un episodio TB y la residencia en una zona periurbana. Se propone que en las personas que consumen o se inyectan drogas se consideren diferentes algoritmos de diagnóstico y tratamiento que comprendan orientación en materia de cumplimiento y un tratamiento de sustitución de opioides.

RESUMO

Fetal supraventricular tachycardia (SVT), characterized by a fetal ventricular heart rate faster than 200 beats per minute (bpm), is often diagnosed during routine fetal heart monitoring or prenatal ultrasound examinations. Clinical guidelines for management of fetal SVT have not been determined in standardized trials, nor do we have a clear sense regarding the long-term developmental outcomes and side effects of in utero antiarrhythmic therapy. We describe our approach to the treatment of refractory SVT in a fetus with hydrops using direct umbilical vein treatment with amiodarone coupled with effusion evacuation. We successfully achieved in utero resolution of SVT. There was transient amiodarone-induced hypothyroidism, which we screened for early and treated with Synthroid. Ultimately our patient had normal long-term growth and development as measured by modified Denver office checklists and Ages and Stages questionnaires. Our experience advocates for vigilant screening and management of hypothyroidism in fetuses exposed to in utero amiodarone and suggests that it is possible to achieve good outcomes in high-acuity refractory cases of SVT.

RESUMO

UNLABELLED: Nano hydroxyapatite (Nano-HA) and Mineral Trioxide Aggregate (MTA) because of its better qualities can be used as an alternative to calcium hydroxide in direct pulp capping procedures. The aim of the study was to compare the response of exposed human pulp to Nano-HA, Mineral Trioxide Aggregate and calcium hydroxide. STUDY DESIGN: The study was done on 30 premolars, ranging from patients between 11-15 years. Intentional pulp capping was done using one of the experimental materials. The extracted teeth were then subjected to staining procedure and evaluated for dentin bridge and pulpal response after 15 and 30 days. Intragroup comparisons of the observed values were analyzed using Chi-square test. RESULTS: Nano-HA and MTA produced continuous dentin bridges. Dentin bridge that was formed in MTA group had regular pattern of dentinal tubules but no tubules were seen in the nano-HA group. Dentin bridge was not observed in Dycal group for the 15 days period in majority of the sample and by 30 days dentin bridge was observed that were both continuous and interrupted in equal number of samples. The initial inflammatory response and necrosis was more with Nano-HA and calcium hydroxide which reduced with time. CONCLUSION: MTA showed no inflammatory changes in majority of the samples in both the study periods. Necrosis was least observed in MTA group followed by Nano-HA. Vascularity increased in Nano-HA group in the initial periods which reduced with increasing time. Based on the ability of nano-HA to produce complete dentinal bridges, favorable cellular and vascular response, the material could be considered as an substitute and could be tried used as a direct pulp capping agent.

RESUMO

INTRODUCTION: Karnataka is an Indian state which has regions with endemic fluorosis. OBJECTIVE: To assess the various defluoridation techniques and units implemented by the Government of Karnataka, along with the cost of installation, maintenance and repair, to mitigate the problem of fluorosis. METHODS: Information regarding the various defluoridation units was obtained from the Panchyath Raj Engineering office before they were visited. Local authorities and residents were interviewed regarding the reasons behind the success or failure of the units. RESULTS: Of the 100 reverse osmosis units installed, 77% are defunct, only one of the two state-of-the-art solar-based technique units is currently functioning but none of the activated alumina or Nalgonda technique units. CONCLUSION: Defluoridation units suitable for Indian conditions and operation by unskilled villagers have yet to be developed.

RESUMO

INTRODUCTION: Newer monomer systems have been introduced in an attempt to improve the success rate of direct composite restorations by minimising shrinkage. AIMS AND OBJECTIVES: To evaluate the in vivo performance of a silorane-based resin composite system (Filtek Silorane, also known as P90), used together with a two-step self-etch bonding system (P90 System Adhesive, Self-Etch Primer and Bond), for the restoration of Class I and Class II cavities in human permanent posterior teeth. MATERIALS AND METHODS: A total of 53 restorations were completed and patients were recalled one year later. The restorations were assessed by two ndependent clinicians, using the Modified U.S. Public Health Service evaluation criteria for the following parameters: retention, colour match, marginal discolouration, secondary caries, anatomic form, marginal adaptation, surface texture, occlusal and interproximal contacts. RESULTS: Of the 41 restorations assessed at the one year follow-up, 92.7% showed clinically acceptable scores for all the parameters evaluated. Cronbach's alpha values ranged from 0.72-1.00 showing a good inter-examiner agreement and reliability. CONCLUSION: Silorane-based composite, Filtek Silorane, when used in conjunction with the recommended adhesive system showed a clinically acceptable performance in posterior teeth restorations over a one year clinical service.

RESUMO

We describe 261 peripheral nerve injuries sustained in war by 100 consecutive service men and women injured in Iraq and Afghanistan. Their mean age was 26.5 years (18.1 to 42.6), the median interval between injury and first review was 4.2 months (mean 8.4 months (0.36 to 48.49)) and median follow-up was 28.4 months (mean 20.5 months (1.3 to 64.2)). The nerve lesions were predominantly focal prolonged conduction block/neurapraxia in 116 (45%), axonotmesis in 92 (35%) and neurotmesis in 53 (20%) and were evenly distributed between the upper and the lower limbs. Explosions accounted for 164 (63%): 213 (82%) nerve injuries were associated with open wounds. Two or more main nerves were injured in 70 patients. The ulnar, common peroneal and tibial nerves were most commonly injured. In 69 patients there was a vascular injury, fracture, or both at the level of the nerve lesion. Major tissue loss was present in 50 patients: amputation of at least one limb was needed in 18. A total of 36 patients continued in severe neuropathic pain. This paper outlines the methods used in the assessment of these injuries and provides information about the depth and distribution of the nerve lesions, their associated injuries and neuropathic pain syndromes.

RESUMO

The outcomes of 261 nerve injuries in 100 patients were graded good in 173 cases (66%), fair in 70 (26.8%) and poor in 18 (6.9%) at the final review (median 28.4 months (1.3 to 64.2)). The initial grades for the 42 sutures and graft were 11 good, 14 fair and 17 poor. After subsequent revision repairs in seven, neurolyses in 11 and free vascularised fasciocutaneous flaps in 11, the final grades were 15 good, 18 fair and nine poor. Pain was relieved in 30 of 36 patients by nerve repair, revision of repair or neurolysis, and flaps when indicated. The difference in outcome between penetrating missile wounds and those caused by explosions was not statistically significant; in the latter group the onset of recovery from focal conduction block was delayed (mean 4.7 months (2.5 to 10.2) vs 3.8 months (0.6 to 6); p = 0.0001). A total of 42 patients (47 lower limbs) presented with an insensate foot. By final review (mean 27.4 months (20 to 36)) plantar sensation was good in 26 limbs (55%), fair in 16 (34%) and poor in five (11%). Nine patients returned to full military duties, 18 to restricted duties, 30 to sedentary work, and 43 were discharged from military service. Effective rehabilitation must be early, integrated and vigorous. The responsible surgeons must be firmly embedded in the process, at times exerting leadership.
