RESUMO

BACKGROUND: Dermatoglyphics has been used widely in fields of medicine as a non-invasive diagnostic tool and an early assessment of risk for certain medical conditions. It reflects disturbances in fetal development during early prenatal weeks 14-22 when fingerprints develop. Dermatoglyphic asymmetry has been used to measure developmental instability during a specific period of human fetal development. Thus, the present study was planned to investigate whether digital and palmar dermatoglyphics of chronic kidney disease of unknown origin (CKDu) patients in Sri Lanka are different from healthy people. METHODS: A case control study was carried out among CKDu patients (90 males, 90 females) from a CKDu endemic area and gender-matched two control groups; one group from a CKDu endemic region (90 males, 90 females) and another group from a CKDu non-endemic region (90 males, 90 females). Dermatoglyphics were obtained using photographic methods. Both qualitative and quantitative dermatoglyphic variables were defined and analyzed according to standard criteria. Both directional (DA) and fluctuating asymmetry (FA) were assessed. RESULTS: Several qualitative dermatoglyphic variables had significant association with CKDu. The triradii a1 variable was less evident in palms of CKDu cases in both genders when compared to both control groups. The FA of pattern discordance (right vs left hands) between CKDu cases and control group were significant in several digits. The FA of the ridge count was found significant in several digits, and also significant for A-B ridge count and total ridge count. CONCLUSION: Based on these results, it is proposed that the mechanisms responsible for the development of CKDu might be associated with those responsible for FA observed in CKDu patients. Accordingly, a diagnostic tool based on FA could be developed for predicting risk prior to the development of CKDu.

RESUMO

Leptospirosis is a zoonotic disease caused by the pathogenic helical spirochetes, Leptospira. Symptoms include sudden-onset fever, severe headaches, muscle pain, nausea and chills. Leptospirosis is endemic in developing countries such as Malaysia, India, Sri Lanka, and Brazil where thousands of cases are reported annually. The disease risk factors include the high population of reservoirs, environmental factors, recreational factors, and occupational factors. To end the endemicity of leptospirosis, these factors need to be tackled. The management of leptospirosis needs to be refined. Early diagnosis remains a challenge due to a lack of clinical suspicion among physicians, its non-specific symptoms and a limited availability of rapid point-of-care diagnostic tests. The purpose of this review is to provide insight into the status of leptospirosis in developing countries focusing on the risk factors and to propose methods for the improved management of the disease.

RESUMO

Screening of plant species with an ability to grow on contaminated soil is the most critical step in the planning of a phytoremediation program. While flourishing growth of Impatiens balsamina L. and Crotalaria retusa L. has been observed in areas adjacent to automobile service stations in Sri Lanka, no systematic study of their tolerance to used lubricating oil (ULO) contaminated soil has been carried out. Therefore, the aim of the present study was to investigate the comparative responses of I. balsamina L. and C. retusa L. to soil contaminated with ULO. Both species exhibited 100% seed germination in soils treated with 1%-5% w/w ULO. After 120 h exposure, root lengths and biomass of germinated seedlings of both species were significantly (p < 0.05) reduced in all treatments above 3% w/w ULO. The measured growth parameters of plants following 90 d exposure to 0.5-3% w/w ULO, indicated significant (p < 0.05) negative effects on I. balsamina and C. retusa at >1% w/w and >2% w/w ULO, respectively. There were no significant effects on chlorophyll content or root anatomy of either species under any treatments. Therefore, we concluded that I. balsamina can tolerate up to 1% of ULO and C. retusa up to 2% w/w ULO without displaying any negative effects. Comparatively higher biodegradation of ULO in the rhizosphere, root nodule formation, increases in root length and root hair density are all possible strategies for the exhibited higher tolerance of C. retusa. Therefore, the overall results indicate that C. retusa has the greater potential to be used in phytoremediation of ULO contaminated soils. The findings of the present study will be beneficial in planning phytoremediation program for ULO contaminated soil.

RESUMO

Methylmercury (MeHg) in rice has attracted growing health concern over the past decade, due to the accumulation of high MeHg levels, which may pose potential health risk to humans. Rice is the staple food in Sri Lanka; nevertheless, the presence of micro pollutants, such as MeHg has been not investigated. Therefore, commercial rice samples from the Sri Lankan market (n = 163) were measured to reveal the total mercury (THg) and MeHg levels. THg (mean: 1.73 ±â€¯0.89 ng/g, range: 0.21-6.13 ng/g) and MeHg concentrations (mean: 0.51 ±â€¯0.37 ng/g; range: 0.03-3.81 ng/g) were low. Compared to the fish MeHg exposure, the rice MeHg exposure was generally lower in different consumption groups, suggesting that rice plays a less role than fish in MeHg exposure in Sri Lanka. Babies (infants and toddlers) at one year old may face fish MeHg exposure (0.17 µg/kg bw/day) higher than the reference dose for MeHg (RfD)-0.1 µg/kg bw/day, which was more than 5 times that of rice MeHg exposure (0.031 µg/kg bw/day). Future studies in Sri Lanka should focus on health impacts under long-term overexposure of MeHg, especially in vulnerable populations. Some diet changes should be made to mitigate MeHg exposure levels in Sri Lankans.

RESUMO

Sri Lanka reports impressive health indicators compared to its peers in the South Asian region. Maternal and infant mortality are relatively low, and several intractable communicable diseases have been eliminated. The publicly financed and delivered "free" healthcare system has been critical to these health achievements. Placing the country's healthcare system in historical context, this commentary analyses the contradictions and political tensions surrounding Sri Lanka's 2018 Universal Health Coverage (UHC) policy, with attention to the Ministry of Health's plans for public-private partnerships (PPP). As economic exigencies and private interests increasingly erode the 1951 "Free Health" policy, this commentary calls for a re-envisioning of UHC that can meet people's aspirations for health and social justice.

RESUMO

This analysis provides new estimates of chronic kidney disease (CKD) prevalence - including CKD of unknown etiology (CKDu) - across ten districts most affected by CKD in Sri Lanka, including an examination of rural households' historical reliance on groundwater consumption. A carefully designed household survey provides information on whether these households self-reported having a member in the decade prior to 2018, who had been clinically diagnosed with CKD. Households were classified according to whether or not they had used groundwater (from household wells, agro-wells or springs) as their primary source for drinking or cooking for at least five years between 1999 and 2018. More than 98% of households reported having consumed groundwater as their primary source of drinking or cooking water for at least five of those years and >15% of households reported having at least one CKD-affected member in the ten-year period up to 2018, but these numbers varied across and within districts. The reported characteristics of symptomatic individuals reveal that the incidence of CKD was significantly higher among females (62%) than males (38%). In addition to CKD, about 63% of symptomatic individuals had hypertension and about one-third of them also had diabetes. About 33% of the symptomatic individuals had neither diabetes nor hypertension, where this group most closely fits commonly used definitions of CKDu. With a survey response of over 8000 households comprising as many as 30,000 individuals, these data illustrate the scale of CKD in the most-affected districts of Sri Lanka on an aggregate basis as well as revealing differences across districts and at the sub-district level.

RESUMO

BACKGROUND: Rabies is estimated to cause 59,000 deaths and economic losses of US$8.6 billion every year. Despite several years of rabies surveillance and awareness programmes, increased availability of post-exposure prophylaxis vaccinations and dog population control, the disease still remains prevalent in Sri Lanka. This study reports the roll-out of a high number, high coverage canine rabies vaccination campaign in Sri Lanka, providing estimates for the vaccination coverage achieved, analysing the local dog demographics, and identifying barriers of attendance to static vaccination clinics. METHODS: A mass dog vaccination campaign was undertaken in Negombo, Sri Lanka. The campaign was composed of static point and door-to-door vaccination stages, with a final survey of vaccination coverage. A large volume of data on the distribution, health, and signalment of vaccinated dogs was collected through a mobile phone application. A logistic regression model was developed to investigate which socio-spatial and dog-related factors influenced attendance of owners to static vaccination points. RESULTS: The campaign vaccinated over 7800 dogs achieving a vaccination coverage of 75.8%. A dog:human ratio of 1:17 was estimated. Most dogs were owned, and the dog population was mostly male, adult, and non-sterilized. Unawareness, unavailability and handling problems were the most common reasons given by owners to explain failure to attend a static vaccination point. The regression analysis showed that increasing distance to a static point, in addition to young age and poor health of the dog, were associated with a decrease in the likelihood of attendance to a static vaccination points. CONCLUSION: This study demonstrates the feasibility of high number, high coverage vaccination campaigns in Sri Lanka. The information on dog ecology and barriers of attendance to static point vaccination clinics will facilitate development of future vaccination campaigns.

RESUMO

Introduction: Pain is one of the most common and unpleasant symptoms that distress the well-being of patients with cancer. Considerable evidence supports the validity and reliability of the McGill Pain Questionnaire (MPQ) and its short forms, the SF MPQ and SF MPQ-2-which are the most widely used tools for pain assessment-in terms of patients with cancer. Pain and its characteristics are best assessed using validated and culturally adapted tools developed in participants' mother tongue. Although many pain assessment tools are available worldwide, only a limited number of them have been translated into Sinhala language and validated in Sri Lanka. We aimed to translate SF MPQ-2 into Sinhala language and validate using Sinhala-speaking patients suffering from cancer pains in Sri Lanka. Materials and Methods: Translation has been conducted according to the guidelines laid down by Mapi Research Trust, in five stages, namely, forward translation, backward translation, expert opinion, cognitive debriefing interviews, and proofreading. The questionnaire was administered among 207 patients attending Apeksha Hospital, Sri Lanka, who are suffering from cancer pain. Content validity was tested using expert opinion, and face validity, by interviewing patients with cancer pain. Factor structure was tested through a factor analysis, and reliability, by internal consistency with Cronbach's alpha. Results: A total of 207 participants (112 males and 95 females), aged between 20 and 80 years, were included in the study. Factor analysis identified four factors compatible with studies done in other countries, which explained 53.5% of the variance. The analysis of data indicated Cronbach's alpha of neuropathic, affective, intermittent, and continuous subscales as 0.768, 0.791, 0.824, and 0.789, respectively, which were over the acceptable threshold of 0.70. Confirmatory factor analysis supported the four-factor model. Conclusion: SF MPQ-2-Sinhala version is a statistically proven reliable and valid pain descriptor which can be utilized to evaluate pain suffered by patients with cancer in Sri Lanka whose mother tongue is Sinhala.

RESUMO

OBJECTIVE: to determine the association between psychological distress and chronic periodontitis in 30-60 year olds residing in Colombo district, Sri Lanka. BASIC RESEARCH DESIGN: an unmatched case control study which included 694 cases and 706 controls. An interviewer administered pre-tested questionnaire was used to obtain information on socio-demographic and behavioural factors while an oral examination was carried out to record periodontal parameters. Psychological distress was assessed using a validated Sinhala version of the General Health Questionnaire-30. PARTICIPANTS: 30-60 year olds residing in Colombo district, Sri Lanka. RESULTS: the odds of having chronic periodontits was nearly three times more (OR=2.71, 95% CI= 2.09-3.51) in those with psychological distress compared to those without psychological distress. Further sex, age group, level of education, current smoking and self reported diabetes were associated with chronic periodontits. CONCLUSION: psychological distress is an independent risk factor for CP in this population.

RESUMO

The genus Phoroncidia Westwood 1835 is currently represented by 81 species and is cosmopolitan in distribution. Currently, four species are known from India, namely Phoroncidia aculeata Westwood 1835, Phoroncidia maindroni (Simon 1905), Phoroncidia septemaculeata O. Pickard-Cambridge 1873 and Phoroncidia testudo (O. Pickard-Cambridge 1873) (World Spider Catalog 2019). P. septemaculeata O. Pickard-Cambridge 1873 was described based on a few specimens collected by Mr G. H. K. Thwaites in 1871 from Sri Lanka and it was mostly derived from the somatic features of the species. Recently, Patil et al. (2018) reported two subadult males presumed to be Phoroncidia septemaculeata from the Maharashtra state in India. Until now, no mature specimen of the species has been reported and its genitalia remains unknown. This paper provides a detailed redescription of P. septemaculeata, including illustrations of male and female genitalia for the first time, based on fresh materials collected from different localities in the Coastal Plains and Western Ghats of Kerala state and Coastal plains of Tamil Nadu. Additionally, the current distributional range and new records of the species is mapped.

RESUMO

The genus Penares Gray 1867 (Tetractinellida Marshall; Astrophorina Sollas; Geodiidae Gray) is reviewed from new and existing New Zealand collections, with 75 specimens examined and registered. The only species known from New Zealand prior to this study, P. tylotaster Dendy 1924, is re-examined and re-described from the holotype, using new scanning electron microscope images. Nine new species are described from New Zealand's Exclusive Economic Zone: P. mollis sp. nov., P. aureus sp. nov., P. vermiculatus sp. nov., P. kermadecensis sp. nov., P. turmericolor, sp. nov., P. deformis sp. nov., P. okokewae sp. nov., P. orbis sp. nov., and P. astronavis sp. nov. A specimen of P. schulzei (Dendy 1905), first described from Sri Lanka and subsequently recorded from New Caledonia, was also found in New Zealand, extending the range of this species. This study brings the total New Zealand Penares fauna to 11 species, making a significant contribution to the now, global total of 39 species. All previously described Penares species are reviewed based on their published descriptions, and species names have been corrected to their masculine form. Based on the published description of P. obtusus Lendenfeld 1907, it is recommended that this species be reassigned to the genus Stelletta Schmidt 1862.

RESUMO

Scolopsis igcarensis Mishra, Biswas, Russell, Satpathy Selvanayagam, 2013 was described from specimens collected from coastal waters of southern India and Sri Lanka. A comparison of recently collected specimens from Bangladesh, initially identified as S. igcarensis, with Scolopsis vosmeri (Bloch, 1792) showed morphological differences between the two species are minor, and that specimens of S. igcarensis in fact represent juvenile and subadult colour forms of S. vosmeri. Underwater and aquarium observations, as well as molecular data based on the COI barcode region, support this conclusion. Accordingly, S. igcarensis is regarded as a junior synonym of S. vosmeri, which is redescribed herein. Phylogenetic analysis of COI barcodes of Scolopsis specimens produced in this study, together with those available from GenBank, indicate S. vosmeri is part of a species complex which includes two additional cryptic sister species that require further taxonomic investigation.

RESUMO

The first recorded regular echinoid species from Sri Lanka, "Salmacis virgulatus" (now known as S. virgulata L. Agassiz in L. Agassiz Desor, 1846), was listed by Agassiz Desor (1846). Knowledge of Sri Lankan regular echinoids continued to advance until the end of the 19th century. However, there is a gap in knowledge between the mid-20th and the beginning of the 21st centuries due to a lack of systematic studies, with the exception of two checklists published by the IUCN Red List in 2006 and 2012. In the present study, we compiled a species list combining published data and new data based on fieldwork between 2013 and 2015. Echinoids were sampled by snorkelling, diving, examination of fisheries bycatch, and collection of tests from beaches. The updated species list presented in this study includes 39 regular echinoids belonging to 28 genera, nine families, and five orders. Phyllacanthus imperialis (Lamarck, 1816) and Temnopleurus toreumaticus (Leske, 1778), which were not recorded during the last 90 years, were confirmed to still occur in Sri Lanka by the present study. We develop an updated species list of regular echinoids to form a basis for future systematic work. The study recommends further investigation to evaluate the status of deep-sea species and additional field work off the northern and eastern coasts of Sri Lanka.

RESUMO

The subfamily Panchaetothripinae comprises 40 extant genera worldwide (ThripsWiki 2019), although only 15 genera are previously recorded from China (Mirab-balou et al. 2016; Li et al. 2018). Panchaetothripinae thrips are characterized by the strong reticulations on the body and leg. Wilson (1975) recognized three tribes in this subfamily, Panchaetothripini, Monilothripini and Tryphactothripini, but only tribe Tryphactothripini was relatively supported based on morphological characters (Mound et al. 2001). Species in this Tribe have abdominal segment II constricted at the base and bearing laterally patches of strong ridges, wart-like tubercles or stoutly recurved microtrichia, and abdominal segment X tends to be asymmetrical. Recently, two further genera of Tryphactothripini were found in Southern China, Noathrips and Opimothrips. These two monotypic genera are reported only from the Old World tropics, Noathrips from India and Sri Lanka, and Opimothrips only from Thailand (Bhatti 1967; Kudô 1979; Nonaka Okajima 1992). The purpose of this paper is to record these two genera from China, together with the first description of the male of Opimothrips tubulatus.

RESUMO

A new frog species of the genus Microhyla (Anura, Microhylidae) is described from riparian mid-elevation (860 m asl) evergreen forest in Namdapha National Park, located in the eastern Himalayan state of Arunachal Pradesh, India. The new species can be morphologically distinguished from other congeners by a suite of characters such as adult size, dorsal and lateral colouration and markings, snout shape, foot webbing, and digit tip morphology. Phylogenetically, the new species is more closely related to some of the smallest known members of the genus. It forms a deeply divergent sister lineage to the clade containing members of the Microhyla zeylanica species group that are restricted to Peninsular India and Sri Lanka, and shows sequential relationship with Southeast Asian species M. superciliaris, followed by clade containing M. aurantiventris + M. butleri. The discovery indicates that novel taxa representing distinct evolutionary lineages still remain to be formally described in the genus Microhyla, especially from less explored regions such as the eastern Himalayan forests in Northeast India.

RESUMO

Last year I reported the rediscovery in Cambodia of Lestes nigriceps Fraser, 1924, described from Pusa, India (Fraser 1924a) but never reported since that time from India (Kosterin 2018). In my paper I presumed non-conspecificity of the male and females of the type series and made critical comments on Fraser's appendage drawing (Fraser 1924a: plate IX: 6) and verbal descriptions (Fraser 1924a; 1933) of this species but did not consider his key for Lestes Leach, 1815 in the 1st volume of "Fauna of British India including Ceylon and Burma. Odonata" (Fraser 1933). Later I found a considerable corruption in this key, which could lead to misidentifications. (It is noteworthy to stress that Fraser explicitly provided keys for males only).

RESUMO

Identities of elasmobranchs from Sri Lanka encountered during collections conducted in an intensive nine-day survey of fish markets and landing sites at 11 localities in the North Western, Northern, and Eastern Provinces in March of 2018 were assessed. In total, 111 specimens representing 34 elasmobranch species were examined. Sequence data for the NADH2 gene were generated for all specimens. Independent Neighbor-Joining analyses, which included data for related taxa, were conducted for 25 subgroups of elasmobranchs to help confirm specific identifications. Five of the 34 species encountered are likely new to science. These consist of one species each of the batoid genera Brevitrygon, Narcine, and Torpedo, and the selachian genera Centrophorus, and Chiloscyllium. The specific identities of 12 species previously known to occur in Sri Lanka are updated to conform to current taxonomy; four of these (Gymnura cf. poecilura 2, Carcharhinus cf. limbatus, Echinorhinus sp. 1, and Iago cf. omanensis 1) represent what appear to be undescribed species reported previously from other localities. Three species (Maculabatis arabica, Acroteriobatus variegatus, and Centroscymnus owstonii) are reported from Sri Lanka for the first time; the latter species also represents the first documented record of this genus and family for the island nation. One of the two specimens on which the recent description of the new species of Planonasus indicus was based was also collected as part of this survey. Although some of the species confirmed to occur in Sri Lanka have also been found in India, others were previously known only from the Persian Gulf, Gulf of Oman, or localities in Southeast Asia. The high amount of novelty discovered as a result of a survey of such short duration emphasizes the importance of more intensive survey efforts in this region now that the civil unrest that precluded such work for nearly three decades has come to an end.

RESUMO

Two new mite species of the genus Gaeolaelaps (Laelapidae), G. lankaensis sp. nov. and G. setillus sp. nov., collected from soil-litter in Sri Lanka, are described and illustrated based on morphological characters of the adult females. Both species have the unusual character state of a three-tined palp tarsal claw. The genus Gaeolaelaps is reported for the first time from Sri Lanka. An updated key to the species with a three-tined palp tarsal claw is presented.

RESUMO

A new species of Cnemaspis is described from southern Sri Lanka. Cnemaspis ingerorum sp. nov. was previously confused with C. kumarasinghei. The new species differs from C. kumarasinghei in having a lower number of ventral scales across midbody, scales on ventral sides of forelimb and hind-limb smooth (versus keeled) and dorsal caudal scales unkeeled (versus keeled). Additionally, Cnemaspis ingerorum sp. nov. has a 4.5% uncorrected ND2 sequence divergence from C. kumarasinghei and is also geographically separated from this species. Existing molecular data supports C. silvula as the sister species of the new form, however, it differs from C. silvula by the absence of keeled pectoral and abdominal scales and dorsal scales, and the absence of keeled (versus keeled) subcaudal scales.

RESUMO

A recent paper dealing with the systematics of Uropeltidae (Pyron et al. 2016) made several taxonomic changes affecting Sri Lankan species in the genera Platyplectrurus Günther, 1868; Pseudotyphlops Schlegel, 1839; Rhinophis Hemprich, 1820; and Uropeltis Cuvier, 1829. Space precluded a full discussion of those changes, for which there was a wealth of additional photographs, data, and references. Here, we expand on those alterations and provide further justification with reference to the ICZN (1999) and additional questions for future research.
