Data from: A revised sectional classification of Plukenetia L. (Euphorbiaceae, Acalyphoideae) with four new species from South America
<p><span><span><span><span><span><span><span><span><span><span><span>We present a phylogenetic classification for <i>Plukenetia</i> (Euphorbiaceae, Acalyphoideae) based on morphology and molecular phylogenetic studies using nuclear (ETS, ITS, <i>KEA1 </i>introns 11 and 17, <i>TEB </i>exon 17) and plastid (<i>matK</i>, <i>ndhF</i>, <i>psbA-trnH</i>) DNA data. <i>Plukenetia</i> comprises 25 species divided into six sections, with three new sections and four new species described here. The circumscription of <i>Plukenetia</i> is unaltered from recent treatments and we continue to recognize <i>Romanoa </i>as distinct. The sections of <i>Plukenetia</i> correspond with the subclade system proposed by Cardinal-McTeague and Gillespie (2016): P1 = <i>P.</i> sect. <i>Fragariopsis</i> comb. et stat. nov.; P2 = <i>P.</i> sect. <i>Penninerviae</i> sect. nov.; P3 = <i>P.</i> sect. <i>Plukenetia</i>; P4 = <i>P.</i> sect. <i>Angostylidium</i>; and P5 = <i>P. </i>sect. <i>Hedraiostylus</i> + <i>P.</i> sect. <i>Madagascarienses </i>sect. nov. The sections are distinguished by a combination of leaf venation, staminate flower morphology, pistillate flower number, style morphology, fruit type, and seed size. Additionally, we describe three new species from South America belonging to sect. <i>Penninerviae</i>: <b><i>Plukenetia brevistyla </i></b>and<b><i> Plukenetia megastyla</i> </b>from the Amazon basin and <b><i>Plukenetia chocoensis</i></b>from the Chocó Biogeographic Region of Colombia. The new Amazonian species are morphologically similar to <i>P. brachybotrya</i> but distinguished by their style shape and size. The new Colombian species is morphologically similar to <i>P. penninervia</i> but distinguished by its elongate basilaminar extrafloral nectaries, presence of abaxial laminar extrafloral nectaries, and longer inflorescences. We also describe a new species from sect. <i>Plukenetia</i>, <b><i>Plukenetia sylvestris</i></b>, which is widespread in central and southern Peru. This species is suggested to be the wild progenitor of the cultivated <i>P. carolis-vegae</i>, differing by its smaller seeds/fruits and fewer stamens. Molecular data, including a new ETS phylogeny sampling <i>P. brevistyla</i>, support our new taxa as distinct. Keys to the sections and species of <i>Plukenetia</i> are provided<i> </i>and we designate 12 new lectotypes for <i>Plukenetia</i> and <i>Romanoa</i>.</span></span></span></span></span></span></span></span></span></span></span></p>

A new sectional classification of Lachenalia (Asparagaceae) based on a multilocus DNA phylogeny
<p><i>Lachenalia</i><b> </b>J.Jacq. ex Murray (Asparagaceae; Scilloideae; Hyacintheae) is a large and morphologically diverse genus of more than 140 bulbous species endemic to southern Africa. Previous attempts to infer a well resolved and robustly supported phylogeny of <i>Lachenalia</i> using Sanger sequencing of candidate loci and/or morphological characters have been largely unsuccessful. Consequently, the current infrageneric classification is artificial and there is a need to explore alternative avenues to produce a phylogenetic classification. In this paper we present a novel phylogenetic hypothesis for <i>Lachenalia</i> inferred using maximum likelihood and coalescent-based species tree estimation (ASTRAL) as applied to 378 hybrid-enrichment loci. Our tree is well resolved and well supported, providing strong support for a monophyletic radiation of the genus in southern Africa and a solid foundation for a revised infrageneric classification. The well-supported placement of <i>L. isopetala</i> Jacq. as sister to <i>Lachenalia</i> + <i>Massonia</i> supports the establishment of a new monotypic genus, <i>Pseudolachenalia</i> G.D.Duncan, to accommodate this species. Conversely, the inclusion of species previously classified as <i>Polyxena</i> Kunth within the <i>Lachenalia</i> clade supports the transfer of these species to <i>Lachenalia</i>. Within <i>Lachenalia</i>, the delimitation of subgenera and sections is complicated by the highly imbalanced character of the phylogeny and by the high levels of homoplasy shown by most morphological characters traditionally used to delimit species in this group. Nonetheless, we propose an infrageneric taxonomy comprising 10 morphologically distinct, monophyletic sections. The largest of these, section <i>Lachenalia</i>, is further divided into 13 more-or-less diagnosable, monophyletic subsections. Keys to the sections of <i>Lachenalia</i>, and to the subsections of section <i>Lachenalia</i>, are provided.</p>

Data from: Clinical spectrum and risk factors associated with asymptomatic erosive esophagitis as determined by Los Angeles classification: a cross-sectional study
Background: Gastro esophageal reflux disease (GERD) is a chronic and recurrent disease, and it varies in regions. However, to date, there are no reports available on clinical features and the risk factors for the asymptomatic reflux esophagitis in Nepalese adults. Methods: Data were gathered from 142 erosive patients who had undergone endoscopy at Bir Hospital, Kathmandu. Los Angeles classification was used to grade the severity of the disease. Patients were interviewed to find out the presence of various reflux symptoms. Results: Based on the Los Angeles classification, the severity of the disease assessed was; grade A 31.8% (31/142), grade B 39.4 % (56/142), grade C 33.8% (48/142), and grade D 4.9% (7/142). One hundred and twenty six (88.7%) subjects had reflux symptoms. Prevalence of asymptomatic esophagits was 16(11.3%). Age was independently linked to asymptomatic esophagitis (P<0.05), and the odd of being asymptomatic appeared lower in younger adults (P<0.05; OR: 0.118; CI: 0.014-.994). Conclusion: A low prevalence of asymptomatic reflux esophagits (RE) was seen. Most subjects experienced mild to moderate RE. Age remained an independent factors associated with reflux esophagitis, and the odd of being asymptomatic was lower in younger age.
