RESUMO
The ability of the Ipswich touch test (IpTT) and VibratipTM to detect loss of protective sensation (LOPS) was tested against a neurothesiometer in an outpatient diabetic population without a history for ulceration. Our results support the use of the IpTT as a screening tool for LOPS, but not of VibratipTM.

BACKGROUND AND AIM: There are efficacy and safety concerns related to teneligliptin treatment. A systematic review of randomized controlled trials (RCTs) was undertaken to comprehensively profile the efficacy and safety of teneligliptin in the treatment of type 2 diabetes mellitus (T2DM). METHODS: Thirteen studies were chosen from a search of scientific databases for RCTs using teneligliptin as a monotherapy or as an adjunct to other glycemic agents with pre-specified inclusion criteria. We calculated weighted mean differences (WMDs) and 95% confidence intervals (CIs) in each included trial and pooled the data using a random-effects model. RESULTS: Thirteen studies enrolled 2853 patients were identified. Teneligliptin treatment was associated with weight gain (vs. placebo, weighted mean difference (WMD) 0.28 kg; 95% CI - 0.20-0.77 kg; I2 = 86%; P = 0.25). Compared to monotherapy, add on therapy with teneligliptin showed significant improvement in FPG mg/dl levels (WMD - 16.75 mg/dl; 95% CI - 19.38 to - 14.13 mg/dl), HOMA-ß (WMD 7.91; 95% CI 5.38-10.45) and HOMA-IR (WMD - 0.27; 95% CI - 0.46 to - 0.07). The improvement in HbA1c was greater with monotherapy (WMD - 8.88 mmol/mol; 95% CI - 9.59 to - 8.08 mmol/mol). There was no significant risk of any hypoglycemia with teneligliptin compared to placebo (OR 0.84; 95% CI 0.44-1.60; I2 = 0%; P = 0.60). However, the risk was 1.84 times high when combined with other glycemic agents. The risk of cardiovascular events was comparable, regardless of treatment duration when compared to placebo or any other active comparator (OR 0.79; 95% CI 0.40-1.57; I2 = 0%; P = 0.50). [PROSPERO, CRD42022360785]. CONCLUSIONS: Teneligliptin is an effective and safe therapeutic option for patients with T2DM, both as monotherapy and as add-on therapy. However, additional large-scale, high-quality, long-term follow-up clinical trials with diverse ethnic populations are required to confirm its long-term efficacy and safety.

Background: Millions of children in low- and middle-income countries (LMICs) experience illness or trauma amenable to emergency medical interventions, but local resources are not sufficient to treat them. Emergency medical services (EMS), including ambulance transport, bridge the gap between local services and higher-level hospital care, and data collected by EMS could be used to elucidate patterns of paediatric health care need and use. Here we conducted a retrospective observational study of patterns of paediatric use of EMS services by children who used EMS in India, a leader in maternal and child EMS development, to inform public health needs and system interventions to improve EMS effectiveness. Methods: We analysed three years (2013-2015) of data from patients <18 years of age from a large prehospital EMS system in India, including 1 101 970 prehospital care records across 11 states and a union territory. Results: Overall, 38.3% of calls were for girls (n = 422 370), 40.5% were for adolescents (n = 445 753), 65.9% were from rural areas (n = 726 154), and most families were from a socially disadvantaged caste or lower economic status (n = 834 973, 75.8%). The most common chief complaints were fever (n = 247 594, 22.5%), trauma (n = 231 533, 21.0%), and respiratory difficulty (n = 161 120, 14.6%). However, transport patterns, including patient sex and age and type of destination hospital, varied by state, as did data collection. Conclusions: EMS in India widely transports children with symptoms of the leading causes of child mortality and provides access to higher levels of care for geographically and socioeconomically vulnerable populations, including care for critically ill neonates, mental health and burn care for girls, and trauma care for adolescents. EMS in India is an important mechanism for overcoming transport and cost as barriers to access, and for reducing the urban-rural gap found across causes of child mortality. Further standardisation of data collection will provide the foundation for assessing disparities and identifying targets for quality improvement of paediatric care.

AIMS: Literature indicates that altered plantar loading in people with diabetes could trigger changes in plantar soft tissue biomechanics which, in turn, could affect the risk for ulceration. To stimulate more research in this area, this study uses in vivo testing to investigate the link between plantar loading and tissue hardness. METHODS: Tissue hardness and plantar pressure distribution were measured for six plantar areas in 39 people with diabetes and peripheral neuropathy. RESULTS: Spearman correlation analysis revealed that increased pressure time integral at the 1st metatarsal-head region (r = -0.354, n = 39, P = 0.027) or at the heel (r = -0.378, n = 39, P = 0.018) was associated with reduced hardness in the same regions. After accounting for confounding parameters, generalised estimating equations analysis also showed that 10% increase in pressure time integral at the heel was associated with ≈ 1 unit reduction in hardness in the same region. CONCLUSIONS: For the first time, this study reveals that people with diabetes and neuropathy who tend to load their feet more heavily also tend to have plantar soft tissues with lower hardness. The observed difference in tissue hardness is likely to affect the tissue's vulnerability to overload injury. More research will be needed to explore the implications of the observed association for the risk of ulceration.

BACKGROUND: Diabetes mellitus has a significant impact on public health. Oxidative stress plays a major role in the pathophysiology of Type 2 Diabetes Mellitus (T2DM), leading to various complications of T2DM. Yoga is being widely used in the management of T2DM. The primary objective of this systematic review and meta-analysis is to understand the effects of yoga on oxidative stress parameters among adult patients diagnosed with T2DM. MATERIALS AND METHODS: Electronic databases such as PubMed, Scopus, Cochrane Library and Science Direct from start of the study till March 2020 were searched to obtain eligible studies. Study designs of all nature were included (except case studies and reviews). The primary outcome was Malondialdehyde (MDA) and secondary outcomes included fasting plasma glucose, HbA1C and Superoxide Dismutase (SOD) levels. RESULTS: A total of four trials with a total of 440 patients met the inclusion criteria. The results of meta-analysis indicated that yoga significantly reduced MDA (SMD: -1.4; 95% CI -2.66 to -0.13; P = 0.03; I2 = 97%), fasting plasma glucose levels (SMD: -1.87: 95% CI -3.83 to -0.09; P = 0.06; I2= 99%), and HbA1c (SMD: -1.92; 95% CI - 3.03 to -0.81; P = 0.0007; I2 = 92%) in patients with T2DM. No such effect was found for SOD (SMD: -1.01; 95% CI -4.41 to 2.38; P = 0.56; I2= 99%). CONCLUSION: The available evidence suggests that yoga reduces MDA, fasting plasma glucose and HbA1C, and thus would be beneficial in the management of T2DM as a complementary therapy. However, considering the limited number of studies and its heterogeneity, further robust studies are necessary to strengthen our findings and investigate the long-term benefits of yoga.

BACKGROUND: The clinical presentation of reduced pupillary responses in orbital apex syndrome is currently not well understood clinically. The pupillary light reflex (PLR) is determined using dynamic pupillometry. CASE DETAILS: A newly diagnosed 35-year-old diabetic female patient had ocular symptoms including orbital pain and ptosis, but no visual loss. Cranial nerve autonomic impairment was identified with dynamic pupillometry and compared with cardiac autonomic activity using heart rate variability (HRV). RESULTS: PLR showed that pupil size and response were severely affected, with a small resting pupil size, and minimal response to a bright white light flash was seen, due to decreased sympathetic activity. However, HRV showed normal cardiac sympathetic activity. CONCLUSION: These findings suggest that orbital apex syndrome may lead to changes in pupil size and response due to compression of sympathetic fibers at the apex of the orbit. Quantitative PLR measurements help to reveal relevant information on anatomical reflex pathways.

Rathke cleft cysts are benign lesions of the sellar and suprasellar region. Extrasellar intrasphenoidal Rathke cleft cysts are rare with only one case reported in pediatric age group. The presenting complaints described include headache and diplopia. We report a case of intrasphenoidal Rathke cleft cyst in a 15-year-old girl who presented with headache and visual disturbances. Neuroimaging showed an expansile cystic lesion involving the sphenoid sinus with mass effect over the pituitary and optic chiasma. Endoscopic decompression of the cystic lesion was done and histopathology of the cyst wall revealed it to be Rathke cleft cyst. Follow-up MRI showed total resection of the cystic lesion with residual partial left optic nerve atrophy.
RESUMO
Antimicrobial resistance is a serious public health threat worldwide today. Escherichia coli is known to resist low doses of antibiotics in the presence of sodium salicylate and related compounds by mounting non-heritable transient phenotypic antibiotic resistance (PAR). In the present study, we demonstrate that Bgl+ bacterial strains harboring a functional copy of the ß-glucoside (bgl) operon and are actively hydrolyzing plant-derived aromatic ß-glucosides such as salicin show PAR to low doses of antibiotics. The aglycone released during metabolism of aromatic ß-glucosides is responsible for conferring this phenotype by de-repressing the multiple antibiotics resistance (mar) operon. We also show that prolonged exposure of Bgl+ bacteria to aromatic ß-glucosides in the presence of sub-lethal doses of antibiotics can lead to a significant increase in the frequency of mutants that show heritable resistance to higher doses of antibiotics. Although heritable drug resistance in many cases is known to reduce the fitness of the carrier strain, we did not see a cost associated with resistance in the mutants, most of which carry clinically relevant mutations. These findings indicate that the presence of the activated form of the bgl operon in the genome facilitates the survival of bacteria in environments in which both aromatic ß-glucosides and antibiotics are present.

BACKGROUND: Access to a trained, competent health care workforce remains a challenge globally, particularly in rural settings. To bridge this gap, the World Health Organization calls for innovations in electronic learning and task shifting. Yet, these approaches are underutilized due to cost, challenges associated with implementing technology, and a lack of suitably educated trainees. OBJECTIVE: We explored the feasibility of the Acute Care Providers Project (ACPP) to remotely train community members to be health care providers in 2 sites: Haiti and India. METHODS: The ACP program is an asynchronous curriculum that provides core health content and a structured approach to clinical care through an electronic curriculum. The curriculum is reinforced with case-based practice and hands-on workshops for procedural skills. ACPP was deployed in rural Haiti and India. Evaluation of the program included multiple-choice pretests and posttests, an objective structured clinical examination (OSCE), and direct observation of skills. RESULTS: Four Haitian and 55 Indian trainees completed the course. In Haiti, mean scores were 34.8% (SD 12.4) on the pretest and 78.0% (SD 6.5) on the posttest (P = .004). Trainees scored 100% on the OSCE and passed the skills checklist. In India, mean scores were 16.5% (SD 3.9) on the pretest and 81.7% (SD 9.0) on the posttest (P < .001). Trainees scored a median of 91.8% (SD 3.95) on the OSCE and all passed the skills checklist. CONCLUSIONS: The ACPP offers a scalable, replicable asynchronous curriculum to train lay individuals to provide basic health care in rural communities.

Regulators encoded by the beta-glucoside (bgl) operon of Escherichia coli are known to influence the expression of downstream target genes that confer a fitness advantage in stationary phase. We have examined the role of bglG in the regulation of ridA that encodes an enamine/imine deaminase essential for the elimination of reactive intermediates generated during the catabolism of amino acids such as serine. We report here that ridA is positively regulated by leucine responsive regulatory protein (Lrp) and leucine antagonizes the activation by Lrp. We also show that Lrp itself is under the indirect regulation of BglG, which brings about the overexpression of ridA in Bgl+ strains during stationary phase. Loss of ridA function in a Bgl+ background results in a significant growth retardation in serine-containing media compared to that in a Bgl- background. We propose that overexpression of ridA in Bgl+ background during stationary phase is physiologically relevant to eliminate toxic metabolites generated by the catabolism of serine-containing peptides as a result of elevated levels of their uptake.

OBJECTIVES: To describe the demographic characteristics and clinical outcomes of neonates born within 7 days of public ambulance transport to hospitals across five states in India. DESIGN: Prospective observational study. SETTING: Five Indian states using a centralised emergency medical services (EMS) agency that transported 3.1 million pregnant women in 2014. PARTICIPANTS: Over 6 weeks in 2014, this study followed a convenience sample of 1431 neonates born to women using a public-private ambulance service for a 'pregnancy-related' problem. Initial calls were deemed 'pregnancy related' if categorised by EMS dispatchers as 'pregnancy', 'childbirth', 'miscarriage' or 'labour pains'. Interfacility transfers, patients absent on ambulance arrival, refusal of care and neonates born to women beyond 7 days of using the service were excluded. MAIN OUTCOME MEASURES: death at 2, 7 and 42 days after delivery. RESULTS: Among 1684 women, 1411 gave birth to 1431 newborns within 7 days of initial ambulance transport. Median maternal age at delivery was 23 years (IQR 21-25). Most mothers were from rural/tribal areas (92.5%) and lower social (79.9%) and economic status (69.9%). Follow-up rates at 2, 7 and 42 days were 99.8%, 99.3% and 94.1%, respectively. Cumulative mortality rates at 2, 7 and 42 days follow-up were 43, 53 and 62 per 1000 births, respectively. The perinatal mortality rate (PMR) was 53 per 1000. Preterm birth (OR 2.89, 95% CI 1.67 to 5.00), twin deliveries (OR 2.80, 95% CI 1.10 to 7.15) and caesarean section (OR 2.21, 95% CI 1.15 to 4.23) were the strongest predictors of mortality. CONCLUSIONS: The perinatal mortality rate associated with this cohort of patients with high-acuity conditions of pregnancy was nearly two times the most recent rate for India as a whole (28 per 1000 births). EMS data have the potential to provide more robust estimates of PMR, reduce inequities in timely access to healthcare and increase facility-based care through service of marginalised populations.

Biosynthesized nanoparticles have an incredible application in biomedicine owing to its simplicity, eco-friendly properties and low cost. The present study aims to determine the green synthesized zinc oxide nanoparticles from methanolic leaf extract of Glycosmis pentaphylla. The synthesized nanoparticles were characterized using UV-VIS Spectroscopy, Fluorescence spectrometer, FT-IR, XRD, SEM with EDAX and TEM. The confirmations of synthesized nanoparticles were characterized by peak at 351 and 410â¯nm in the UV-VIS spectrum and photoluminescence spectrum respectively. FT-IR studies revealed the functional group of the nanoparticles. The XRD data showed the crystalline nature of the nanoparticles and EDAX measurements indicated the 20.70% of highly pure zinc oxide metal. The morphological characterization of synthesized zinc oxide nanoparticles was analyzed by SEM and TEM and size of the particles were ranging from 32 to 36â¯nm. The synthesized zinc oxide nanoparticles exhibited interesting antimicrobial activity against pathogenic organisms. In addition, this is the first report on leaf mediated synthesis of zinc oxide (ZnO) nanoparticles from Glycosmis pentaphylla.

The phase 2, open-label ACCORDION (ClinicalTrials.gov: NCT02349048) study investigated the efficacy, safety and pharmacokinetics of a 6- or 8-week regimen of simeprevir, daclatasvir and sofosbuvir in treatment-naïve patients with chronic hepatitis C virus (HCV) genotype (GT) 1 infection and either early-stage fibrosis or compensated cirrhosis. Patients were assigned to treatment groups according to their fibrosis stage. Early-stage fibrosis: simeprevir 150 mg, daclatasvir 60 mg, sofosbuvir 400 mg once daily for 6 weeks; compensated cirrhosis: same regimen for 8 weeks. The primary endpoint was sustained virologic response 12 weeks after the end of treatment (SVR12). Safety, tolerability and pharmacokinetics of simeprevir, daclatasvir and sofosbuvir were investigated. Sixty-eight patients were treated (6-week group: n = 59; 8-week group: n = 9). SVR12 was achieved by 86.4% (51/59) of patients with early-stage fibrosis and by 100% (9/9) of patients with cirrhosis. The main reason for not achieving SVR12 in the 6-week group was viral relapse (11.9%; 7/59). One patient had on-treatment failure due to an early withdrawal (lost to follow-up due to incarceration). One patient with SVR12 in the 6-week group had a late viral relapse at post-treatment week 24. No clinically significant drug-drug interactions were observed. Adverse events were reported in 63.2% of patients (43/68) and were mainly grade 1/2. None of these led to treatment discontinuation. The 3 direct-acting antiviral regimens of simeprevir, daclatasvir and sofosbuvir were safe and well tolerated in treatment-naïve, HCV GT1-infected patients with early-stage fibrosis or compensated cirrhosis.

In the present study deals with the green synthesis of silver nano particles from methanolic leaf extracts of Atalantia monophylla. The synthesized nano-particles are characterized by UV-vis spectroscopy, PL, FTIR, XRD, SEM with EDAX and TEM. The nano-particles are indicated in absorption peak at 404 nm in the absorption spectrum. Further micro graphical analysis confirmed the average size was estimated about 35 nm and SEAD pattern authorized well crystalline materials. The FTIR studies help to confirm the functional group of synthesized silver nano particles. The XRD data shown the crystalline nature of nano particles and EDAX measurement indicates the purity of silver metal. The antimicrobial effect of silver nanoparticles was tested on pathogenic organisms using agar well diffusion method. Minimum inhibitory concentration (MIC) and Minimum bactericidal/fungicidal concentration (MBC/MFC) were also investigated in different concentrations of leaf extract. The results indicated that synthesized silver nano particle of A. monophylla leaf extract has the potential of antimicrobial activity against pathogenic microorganism. In addition, this is the first report on leaf synthesized silver nano particles of A. monophylla. The antimicrobial activity against pathogenic microorganisms and the ability to detect hydrogen peroxide using the silver nanoparticles were confirmed which would find applications in the development of new antimicrobial drugs and new biosensors to detect the presence of hydrogen peroxide in various samples respectively.

Primary hyperoxaluria (PH) Type 1 is a rare, genetic disorder caused by deficiency of the liver enzyme alanine-glyoxylate aminotransferase, which is encoded by AGXT gene. We report a 2-year-old South Indian Tamil child with nephrocalcinosis due to PH Type 1, in whom a homozygous genotype for two missense mutations in the AGXT gene was found: first, a C to G transversion (c. 32C>G) in exon 1 resulting in the amino acid substitution p.Pro11Arg; second, a T to A transversion (c. 167T>A) in exon 2 resulting in p.Ile56Asn. A therapy based on potassium citrate and pyridoxine was started. This is the first report of molecular testing-proven childhood onset-PH Type 1 from South India and is notable for the co-occurrence of two missense mutations in one AGXT allele, which might lead to different and more severe phenotype than each mutation alone. To the best of our knowledge, AGXT allele carrying two already known mutations has not been previously reported.
RESUMO
Approximately three million individuals in the United States are chronically infected with hepatitis C virus (HCV). Chronic HCV infection may lead to the development of compensated as well as decompensated liver cirrhosis. The Phase II IMPACT study was conducted in HCV genotype 1- or 4-infected cirrhotic patients with portal hypertension or decompensated liver disease and assessed for the first time the combination of the three direct-acting antivirals simeprevir, daclatasvir and sofosbuvir. Treatment-naïve or treatment-experienced adults with Child-Pugh (CP) score <7 (CP A) and evidence of portal hypertension, or CP score 7-9 (CP B), received 12 weeks of simeprevir 150 mg, daclatasvir 60 mg and sofosbuvir 400 mg, once daily. The primary efficacy endpoint was sustained virologic response 12 weeks after end of treatment (SVR12). Pharmacokinetics and safety were also assessed. Overall, 40 patients were enrolled (CP A: 19; CP B: 21). All 40 patients achieved SVR12. At week 8, the mean pharmacokinetic exposure to simeprevir, sofosbuvir, daclatasvir and GS-331007 (sofosbuvir metabolite) was 2.2-, 1.5-, 1.2- and 1.2-fold higher in patients with CP B than CP A, respectively. Grade 1/2 adverse events (AEs) occurred in 26 of 40 (65%) patients. One CP B patient had a Grade 3 AE (gastrointestinal haemorrhage), which was reported as a serious AE but not considered related to study drugs. Treatment for 12 weeks with simeprevir, daclatasvir and sofosbuvir was generally safe and well tolerated, and resulted in 100% of cirrhotic patients with portal hypertension or decompensated liver disease achieving SVR12.

SETTING: Postgraduate (PG) residency programme of a tertiary care teaching hospital in southern India. OBJECTIVE: To estimate the incidence of tuberculosis (TB) among PG residents, determine the frequency of exposure to infectious TB patients and assess whether particular specialties were associated with higher risk of exposure and incident TB. DESIGN: We assembled an open cohort of PG residents who were on the academic rolls for more than 3 months at any time between December 2011 and January 2013. We collected data both retrospectively and prospectively using two surveys-an entry survey at study initiation or entry into the cohort, and an exit survey at residency completion or study closure. RESULTS: Among 398 PG residents enrolled in the study, we identified five cases of incident TB during a cumulative follow-up period of 10 962 person-months. The incidence rate was 547 per 100 000 person-years, which was 3.1 times the incidence in the general population. Nearly two thirds (n = 257, 65%) of the residents were exposed to at least one infectious patient. Across the three specialty-based risk strata, there was an ordered increase in the median number of exposures (P < 0.001) and evaluation for presumptive TB (P = 0.024), as well as a trend towards higher incident TB. CONCLUSION: TB incidence is significantly higher among PG residents than in the general population.

OBJECTIVES: Characterise the demographics, management and outcomes of obstetric patients transported by emergency medical services (EMS). DESIGN: Prospective observational study. SETTING: Five Indian states using a centralised EMS agency that transported 3.1 million pregnant women in 2014. PARTICIPANTS: This study enrolled a convenience sample of 1684 women in third trimester of pregnancy calling with a 'pregnancy-related' problem for free-of-charge ambulance transport. Calls were deemed 'pregnancy related' if categorised by EMS dispatchers as 'pregnancy', 'childbirth', 'miscarriage' or 'labour pains'. Interfacility transfers, patients absent on ambulance arrival and patients refusing care were excluded. MAIN OUTCOME MEASURES: Emergency medical technician (EMT) interventions, method of delivery and death. RESULTS: The median age enrolled was 23â years (IQR 21-25). Women were primarily from rural or tribal areas (1550/1684 (92.0%)) and lower economic strata (1177/1684 (69.9%)). Time from initial call to hospital arrival was longer for rural/tribal compared with urban patients (66â min (IQR 51-84) vs 56â min (IQR 42-73), respectively, p<0.0001). EMTs assisted delivery in 44 women, delivering the placenta in 33/44 (75%), performing transabdominal uterine massage in 29/33 (87.9%) and administering oxytocin in none (0%). There were 1411 recorded deliveries. Most women delivered at a hospital (1212/1411 (85.9%)), however 126/1411 (8.9%) delivered at home following hospital discharge. Follow-up rates at 48â hours, 7â days and 42â days were 95.0%, 94.4% and 94.1%, respectively. Four women died, all within 48â hours. The caesarean section rate was 8.2% (116/1411). On multivariate regression analysis, women transported to private hospitals versus government primary health centres were less likely to deliver by caesarean section (OR 0.14 (0.05-0.43)) CONCLUSIONS: Pregnant women from vulnerable Indian populations use free-of-charge EMS for impending delivery, making it integral to the healthcare system. Future research and health system planning should focus on strengthening and expanding EMS as a component of emergency obstetric and newborn care (EmONC).

OBJECTIVES: To validate and assess reliability of a novel triage system, one-two-triage (OTT), that can be applied by inexperienced providers in low-resource settings. METHODS: This study was a two-phase prospective, comparative study conducted at three hospitals. Phase I assessed criterion validity of OTT on all patients arriving at an American university hospital by comparing agreement among three methods of triage: OTT, Emergency Severity Index (ESI) and physician-defined acuity (the gold standard). Agreement was reported in normalised and raw-weighted Cohen κ using two different scales for weighting, Expert-weighted and triage-weighted κ. Phase II tested reliability, reported in Fleiss κ, of OTT using standardised cases among three groups of providers at an urban and rural Cambodian hospital and the American university hospital. RESULTS: Normalised for prevalence of patients in each category, OTT and ESI performed similarly well for expert-weighted κ (OTT κ=0.58, 95% CI 0.52 to 0.65; ESI κ=0.47, 95% CI 0.40 to 0.53) and triage-weighted κ (κ=0.54, 95% CI 0.48 to 0.61; ESI κ=0.57, 95% CI 0.51 to 0.64). Without normalising, agreement with gold standard was less for both systems but performance of OTT and ESI remained similar, expert-weighted (OTT κ=0.57, 95% CI 0.52 to 0.62; ESI κ=0.6, 95% CI 0.58 to 0.66) and triage-weighted (OTT κ=0.31, 95% CI 0.25 to 0.38; ESI κ=0.41, 95% CI 0.35 to 0.4). In the reliability phase, all triagers showed fair inter-rater agreement, Fleiss κ (κ=0.308). CONCLUSIONS: OTT can be reliably applied and performs as well as ESI compared with gold standard, but requires fewer resources and less experience.
