The adult head of Axymyia furcata (Insecta: Diptera: Axymyiidae)
Authors: Schneeberg Katharina , Krause Katrin , Beutel Rolf
Published: July 2023

The external and internal cephalic morphology of males and females of Axymyia furcata is described and illustrated in detail. The documented features are compared with those of potentially related groups. Axymyia displays a number of apomorphic features of the adult head, like the subdivision of the compound eyes, the absence of several mucles (M. clypeolabralis, M. stipitopalpalis externus, M. palpopalpalis maxillae primus, Mm. palpopalpalis maxillae primus and secundus), the absence of both maxillary endites, and the loss of the salivary pump musculature (M. hypopharyngosalivarialis). Another apomorphic character is the origin of M. tentorioscapalis anterior on the head capsule. Some features are plesiomorphic and probably belong to the groundplan of Diptera: the orthognathous head, three ocelli, 5-segmented maxillary palps, 2-segmented labial palps transformed into medially fused labella, one premental retractor, a dense vestiture of microtrichia on all exposed parts of the head except the labrum, and the presence of an epipharyngeal food channel. The systematic position of Axymyiidae is discussed. Our findings do not provide support for the phylogenetic position of Axymyiidae.

Authors: Pino Modesto , Hernández-Suárez Estrella , Cabello Tomas , Rugman-Jones Paul , Stouthamer Richard , Polaszek Andrew
Published: July 2023

A new species of Trichogramma Westwood (Hymenoptera: Trichogrammatidae) parasitizing eggs of the golden twin-spot moth (or tomato looper) Chrysodeixis chalcites (Esper) (Lepidoptera: Noctuidae) on banana crops in the Canary Islands, Spain, is described as Trichogramma canariensis del Pino & Polaszek, sp.n. The new species is closely related to T. brassicae Bezdenko. Limited aspects of morphology, coupled with ITS2 and COI sequences and reproductive data are presented to distinguish T. canariensis sp.n. from T. brassicae.
Mating and genital coupling in the primitive earwig species Echinosoma denticulatum (Pygidicranidae): implications for genital evolution in dermapteran phylogeny
Authors: Kamimura Yoshitaka , Lee Chow-Yang
Published: July 2023

Dermaptera (earwigs) shows much diversity in the genital structures, the presence of either one or two male intromittent organs (penes) being one striking aspect. The members of several groups (Karschiellidae, Eudermaptera, Arixeniina, and Hemimerina) possess a single functional penis, while others have a pair of penes. The latter condition is considered to be plesiomorphic in Dermaptera. Despite its importance for inferring the phylogeny of Dermaptera, it is presently unclear how the ancestor of earwigs acquired paired penes. To estimate the mode of mating and sperm transfer in the common ancestor of extant earwigs, this study examines the mating behavior and genital coupling of the primitive earwig species Echinosoma denticulatum Hincks, 1959 as a representative of Pygidicranidae, one of the basal-most assemblages of earwigs. Staged mating experiments, including surgical manipulation of male penes revealed the following characteristics for this species: (1) males use only one of the paired penes for a single genital coupling; (2) both penes are likely functional; (3) there are no consistent biases in usage of the penes; (4) laterality of the penis-use pattern is not related to the direction of rotation of the male abdomen to establish genital coupling; (5) sperm are transferred directly into the spermatheca, a female sperm storage organ; (6) the spined area of the penis inflicts wounds on the vagina around the spermathecal opening, which bears many setae, during copulation. Characteristics (1)–(4) are considered to be plesiomorphic and may represent the condition of the common ancestor. Traumatic penetration during copulation is reported for earwigs for the first time. Together with intermittent acceptance of courting males by females only after a certain interval, these results suggest sexual conflict over mating in this species.
Description of a new species of Glaresidae (Coleoptera: Scarabaeoidea) from the Jehol Biota of China with a geometric morphometric evaluation
Authors: Bai Ming , Beutel Rolf , Liu Wangang , Li Sha , Zhang Mengna , Lu Yuanyuan , Song Keqing , Ren Dong , Yang Xing-Ke
Published: July 2023

Glaresis tridentata Bai, Beutel & Ren sp. nov. (Scarabaeoidea: Glaresidae) from the Yixian Formation of western Liaoning Province, NE China is described and illustrated. A geometric morphometric analysis of three character systems (head, metatibia and aedeagus) was carried out including 136 specimens from 44 species of three genera of extant and extinct Glaresidae. The variation in these features between Glaresis tridentata Bai, Beutel & Ren sp. nov. and the other species was estimated based on Principal Component Analysis (PCA), Canonical Variate Analysis (CVA), Discriminant function analysis (DFA) and Minimum Spanning Tree (MST) approaches. The results suggest that Glaresidae, likely the sister group of all other extant Scarabaeoidea, had been established in the Early Cretaceous and contained larger species than today. The assignement of the new species to the genus Glaresis is supported. The validity of the genera Lithoglaresis and Cretoglaresis is questionable.
Cryptic diversity of caddisflies in the Balkans: the curious case of Ecclisopteryx species (Trichoptera: Limnephilidae)
Authors: Previšić Ana , Graf Wolfram , Vitecek Simon , Kučinić Mladen , Bálint Miklós , Keresztes Lujza , Pauls Steffen , Waringer Johann
Published: July 2023

Adults and larvae of two new cryptic, endemic caddisflies, Ecclisopteryx keroveci sp.n. and Ecclisopteryx ivkae sp.n., are described and illustrated from the Western Balkans. Phylogenetic analysis (Bayesian MCMCMC) and association of different life history stages in both cryptic species were achieved through comparison of morphological characters and mitochondrial (mtCOI and mtLSU) and nuclear (nuWG) gene sequence data. The new species form a sister clade to the widely distributed E. dalecarlica and E. guttulata, with which they were formerly misidentified. Adults differ from each other and other species in the genus by the uniquely shaped inferior appendages in males and segment X in females. The larvae differ from each other and their congeners in the shape of the pronotum, and presence and constitution of additional spines on the parietalia. Larvae of both species are grazers and prefer stony substrate. Ecclisopteryx keroveci sp.n. has a wide distribution in the Western Balkans, while E. ivkae sp.n. is endemic to Dalmatia. Our findings demonstrate the significance of the Western Balkans as a freshwater biodiversity hotspot, and accentuate the importance of research focused on freshwater biodiversity and biogeography in southern Europe.
Moving toward species-level phylogeny using ribosomal DNA and COI barcodes: an example from the diverse caddisfly genus Chimarra (Trichoptera: Philopotamidae)
Authors: Kjer Karl , Zhou Xin , Frandsen Paul , Thomas Jessica , Blahnik Roger
Published: July 2023

The genus Chimarra (Trichoptera, Philopotamidae) is a cosmopolitan genus with over 700 species. The taxonomic history of Chimarra is discussed, with reference to how large genera are best subdivided. We also examine the phylogenetic utility of the COI “barcode” fragment and find it to be phylogenetically useful, within limits. Adding a single fragment of nuclear rRNA (specifically the 28S D2 region) converts the barcode hypothesis into a strongly supported phylogeny that is corroborated by a morphologically derived subgeneric classification. This suggests that a simple two gene dataset could be combined with morphological data in order to rapidly and inexpensively include a molecular component to generic revisions. We confirm the monophyly of Chimarra (Chimarra), C. (Curgia), C. (Otarrha), and core C. (Chimarrita). The C. (C.) tsudai group is also recovered. We make use of web-based materials, including the BOLD website (http://www.boldsystems.org/), and keyhole markup language files (.kml format), which permit specimen data to be viewed on Google Earth. We suggest that static phylogenies presented in print could be dynamically updated with the use of these web materials.
Molecular phylogeny of the leaf beetle subfamily Criocerinae (Coleoptera: Chrysomelidae) and the correlated evolution of reproductive organs
Authors: Matsumura Yoko , Yao Izumi , Beutel Rolf , Yoshizawa Kazunori
Published: July 2023

Phylogenetic relationships among major groups of Criocerinae were reconstructed using molecular data (mitochondrial cytochrome oxidase I and 12S rDNA, and nuclear histone 3). The monophyly of Criocerinae was consistently and robustly supported. The Lema group including Lema, Oulema and Neolema was recovered as a clade, with the latter two genera imbedded within Lema. The Lilioceris group was placed as the sister taxon of the Lema group, and the genus Crioceris was identified as the sister taxon of the Lilioceris + Lema groups. The monophyly and/or validity of Mecoprosopus Chûjô, 1951 and the subgenera Lema, Petauristes Latreille, 1829, Quasilema Monrós, 1960, Microlema Pic, 1932, and Bradyceris Chûjô, 1951 were not confirmed. The monophyly of the subgenus Lema except for the type species L. cyanea was supported by molecular and morphological data, and we termed it the cyanella clade. The present molecular phylogeny was compared with previous concepts with respect to the validity of each genus/subgenus. A revision of several genera is necessary. Based on the phylogenic result, the character evolution of the reproductive organs was analyzed. The ancestral states of this character system were parsimoniously reconstructed. Various shapes of the spermatheca were observed in the subfamily. A convoluted spermatheca evolved once, and reversals to the ancestral state took place several times independently. An elongation of a part of the intromittent organ also occurred several times independently. The length of the male and female reproductive ducts, which are in physical contact during copulation, showed a tight positive correlation even after removing phylogenetic effects. This strongly suggests coevolution between the male and female genital length.
A single endemic and three exotic species of the termite genus Coptotermes (Isoptera, Rhinotermitidae) in the New World
Authors: Scheffrahn Rudolf , Carrijo Tiago , Křeček Jan , Su Nan-Yao , Szalanski Allen , Austin James , Chase James , Mangold John
Published: July 2023

The termite genus Coptotermes is both large and widespread but, as a whole, lacks robust diagnostic characters for morphological species identification. This has resulted in many taxonomic synonymies leading to the current pool of extant species a few of which are among the world’s most destructive pests of wood. The New World diversity of Coptotermes is far less complicated, but has not been the subject of critical study. Using a large collection representative of endemic Coptotermes from the region, we compared their external morphology and their 16S genetic marker sequences to identify the three described American species: C. crassus, C. niger, and C. testaceus. We found no consistent differences among populations from Mexico to Bolivia, and therefore, we reassign the former two species as junior synonyms of C. testaceus. We also compared alates and soldiers of the three non-native species of Coptotermes: C. formosanus, C. gestroi, and C. sjostedti (soldiers only) to C. testaceus and provide diagnostic characters to identify all four current New World species. An updated distribution map is provided.
The larval cephalic morphology of the enigmatic boreid Caurinus dectes (Mecoptera) and its phylogenetic significance
Authors: Fabian Benjamin , Russell Loren , Friedrich Frank , Beutel Rolf
Published: July 2023

The species Caurinus dectes was described in 1979 by L. Russell and assigned to the mecopteran family Boreidae. A description of the immature stages published three years later provided important information. In the present study we re-examined larvae which became available through recent collecting efforts. External and internal features of the head are described and documented in detail. The systematic position of Caurinus and Boreidae is discussed. The orthognathous head is mainly characterized by plesiomorphic features such as the complete tentorium with well-developed dorsal arms and a broad bridge, the presence of seven well-developed stemmata, the free labrum, the simple mandibles with a basal molar area but without complex mesal appendages, the presence of a tentorio-mandibular muscle, the well-developed set of dorsal and ventral pharyngeal dilators, the placement of the brain and suboesophageal ganglion within the head, and the presence of an occipital furrow. Derived features are deformations of the brain related to size reduction and the greatly reduced labium. The phylogenetic interpretation remains ambiguous. The orthognathous head and some postcephalic features are potential synapomorphies of Boreidae and Pistillifera, whereas the presence of secondary compound eyes is a potential synapomorphy of Pistillifera and Nannochoristidae.
Functional morphology of the mandibular apparatus in the cockroach Periplaneta americana (Blattodea: Blattidae) - a model species for omnivore insects
Authors: Weihmann Tom , Kleinteich Thomas , Gorb Stanislav , Wipfler Benjamin
Published: July 2023

We examine the functional morphology of the mandibular apparatus, including its driving muscles, of the generalist insect Periplaneta americana using a combination of μ-computed tomography and geometrical modelling. Geometrical modelling was used to determine the changes of the mean fibre angle and length in the mandibular adductor muscle over the physiological range of mandible opening. The roughly scissor-like mandibles are aligned along the dorso-ventral axis of the head and are characterised by sharp interdigitating distal teeth, as well as a small proximal molar region. The mechanical advantage of the mandibles, i.e. the ratio between inner and outer levers, ranges between 0.37 to 0.47 depending on the considered incisivus. The mandibular abductor muscle is comprised of eight muscle fibre bundles, which are defined by distinct attachment positions on the sail-like apodeme protruding from the medio-lateral basis of the mandibles into the head lumen. Compared to carnivorous, herbivorous, or xylophagous insects, the relative volumes of the mandibular abductor and adductor muscle are small. Dependent on the mandible opening angle, the mean fibre angle of the adductor muscle ranges from 34° to 21°, while mean fibre length changes from 1.24 mm (closed mandible) to 1.93 mm at maximum mandible opening. Many of the specific morphological features found in the chewing apparatus of P. americana, such as the presence of a mola in combination with distal incisivi, small relative muscle size and the intermediate fibre angle can be understood as adaptations to its omnivorous life style.
Molecular phylogeny of the cave beetle genus Hadesia (Coleoptera: Leiodidae: Cholevinae: Leptodirini), with a description of a new species from Montenegro
Authors: Polak Slavko , Delić Teo , Kostanjšek Rok , Trontelj Peter
Published: July 2023

Hadesia is a charismatic and scientifically important genus of cave beetles. It is a classical representative of the subterranean fauna of the Dinaric Karst and the model upon which the ultra-specialized ecomorphological form of semi-aquatic, hygropetricolous filter feeders became known. We describe a new species, Hadesia zetae sp.n., from southwestern Montenegro, and employ new morphological characters to build an identification key to all five species of the genus. Based on DNA sequence data from two nuclear and two mitochondrial genes and using multispecies coalescent methods, we corroborated their reciprocal monophyly and inferred a well-supported phylogenetic hypothesis. Molecular dating suggests that the most recent common ancestor of the extant Hadesia species lived about three million years ago, during the warm and wet mid-Pliocene, and diversified allopatrically through range fragmentation caused by habitat reduction during the Pleistocene. Because of their extreme rarity and observed negative impact of collection pressure, we discourage collecting of Hadesia at known sites.
The head of the earwig Forficula auricularia (Dermaptera) and its evolutionary implications.
Authors: Neubert David , Simon Sabrina , Beutel Rolf , Wipfler Benjamin
Published: July 2023

The external and internal head morphology including the musculature of the common earwig Forficula auricularia is described in detail. We specified and corrected previous descriptions and provided a detailed documentation. The head of Forficula is characterized by prognathism, generalized mandibles with a mesal cutting edge distally of the mola and its drop-shaped appearance. We added the following new apomorphies for Dermaptera to the various previously reported ones: (I) coronal and frontal cleavage lines with corresponding strong internal strengthening ridges; (II) the division of the praementum into a basal and a distal sclerite; (III) the presence of a bumpulus at the tip of the paraglossa; (IV) the presence of large distal palpilla on the terminal maxillary and labial palpomeres and (V) the origin of M. tentoriohypopharyngealis on the submentum. Another potential apomorphy are the lateral lobes on the distal hypopharynx which are most likely not homologous to the superlingua of apterygote insect. Other characters such as the prominent ball-and-socket joint between scapus and pedicellus or the unique antennal heart are poorly studied within Dermaptera and therefore cannot be phylogenetically polarized. In contrast to the various ordinarial apomorphies, the dermapteran head exhibits only one potential synapomorphy with other polyneopteran orders: the absence of the linguactual tendon and the associated muscle that is shared with Plecoptera and/or Zoraptera. Our results show that additional studies of the presumingly basal splits of Dermaptera are required to understand the head evolution of the group.
The Hydropsyche instabilis group (Trichoptera: Hydropsychidae) on the Iberian Peninsula: evolutionary relationships, new species, taxonomical controversies, and a key to larvae. Arthropod Systematics & Phylogeny 75 (1): 159-172 PDF 1.7 MB
Authors: Zamora-Muñoz Carmen , Múrria Cesc , Bonada Núria , González Marcos
Published: July 2023

The Hydropsyche instabilis group is a diverse Palearctic group composed of more than 30 species, many of them local endemics. The exact number of species in the Mediterranean Basin remains ambiguous, mainly due to the high variability of the genitalia and the lack of indepth taxonomic studies in some areas. In this paper, we describe the adult male and the larva of a new species from the Iberian Peninsula (Hydropsyche solerorum sp.n.), and provide information about the ecological requirements of the larvae. We also discuss the identity of a species, provisionally designated as Hydropsyche cf. spiritoi. The morphology of the imago genitalia does not allow us to distinguish it from H. spiritoi, but the two forms show some larval morphological differences, molecular divergence at the mtDNA gene cox1, and, apparently, non-overlapping geographical distributions. In addition, we present a complete molecular phylogeny for the mtDNA gene cox1 of the currently known Iberian species of the instabilis group to determine the evolutionary position of H. solerorum, H. cf. spiritoi, and the two other endemic species H. ambigua and H. fontinalis. Finally, we provide an update of the identification key for the known larvae of the genus Hydropsyche on the Iberian Peninsula.
Head morphology of the smallest beetles (Coleoptera: Ptiliidae) and the evolution of sporophagy within Staphyliniformia
Authors: Yavorskaya Margarita , Beutel Rolf , Polilov Alexey
Published: July 2023

Ptiliidae include the smallest known beetles. External and internal head structures of species with different body sizes and feeding preferences were examined and described in detail. Saprophagous and sporophagous species are compared. The observed features are evaluated with respect to their phylogenetic and functional significance, and their correlation with extreme size reduction. A putative autapomorphy of Staphyliniformia is an unusual extrinsic maxillary muscle, which among ptiliids is only present in the saprophagous species. Synapomorphies of Ptiliidae and their sister group Hydraenidae are a lateral mandibular process forming a unique locking device with a lateral groove of the labrum, and mandibles divided into a main body and a mesal molar part, both connected by a membrane. Extreme body size reduction is a presumptive autapomorphy of Ptiliidae that probably resulted in the following derived features: the loss of cephalic sutures and ridges, a simplified tentorium, and a brain modified in shape and very large in relation to the head size. The ptiliid species with saprophagous and sporophagous feeding habits show only subtle differences in their cephalic structures, notably in details of the epipharynx and galeae and in the configuration of maxillary muscles. Two alternative scenarios are suggested for the evolution of feeding habits, based on the morphological results and presently available information on phylogenetic relationships. One option is to assign saprophagy to the groundplan of the family, with two switches to sporophagy; first in the basal Nossidium and then a second time in the extremely small Nanosellini, which are characterized by feeding habits that we address as microsporophagy. An alternative scenario is that feeding on spores is ancestral for Ptiliidae, with reversals to saprophagy in several branches of the family, and a specialization on very small spores in the strongly miniaturized nanoselline species. A well-founded species level phylogeny of Ptiliidae with a dense taxon sampling will help to clarify this issue.
Dynamic Information Provision: Rewarding the Past and Guiding the Future
Authors: Ball Ian
Published: July 2023

I study the optimal provision of information in a long‐term relationship between a sender and a receiver. The sender observes a persistent, evolving state and commits to send signals over time to the receiver, who sequentially chooses public actions that affect the welfare of both players. I solve for the sender's optimal policy in closed form: the sender reports the value of the state with a delay that shrinks over time and eventually vanishes. Even when the receiver knows the current state, the sender retains leverage by threatening to conceal the future evolution of the state.
Microscopic Formation Mechanism and Physical Properties of Mo/Cu Composites with High Densification
Authors: Li Qing , Li Zeng De , Xie Hao Feng , Peng Li Jun , Mi Xu Jun
Published: July 2023

The formation mechanism and physical properties of high-densification Mo/Cu composites are studied by analyzing materials' microstructure, atom diffusion near the phase interface and physical properties. In the liquid phase sintering, the atomic diffusion occurs at the interface of molybdenum and copper, mainly the diffusion of copper atoms into molybdenum phase. Copper atoms in the material diffuse into the molybdenum phase to form a micron sized Cu-Mo solid solution, and no compound phase is found in the material structure, which forms a good interface bonding effect and makes it have high densification. The average linear expansion coefficients, thermal conductivities, electrical conductivities and tensile strengths of high-densification Mo/Cu composites with different copper content are linearly correlated with copper content. Mo80Cu20 is organized as a connected molybdenum skeleton and a small amount of copper phase in the voids. The tensile fracture of Mo80Cu20 is mainly exhibited as brittle fracture of the sintering neck of the molybdenum phase. The copper phase in Mo70Cu30, Mo60Cu40 or Mo50Cu50 is in a connected state, with plasticity significantly increased. Under the action of tensile stress, the ductile fracture of copper phase and the brittle fracture of sintering neck of the molybdenum phase occur simultaneously in these materials.
Interaction of Hydrogen with Reduced Graphene Oxide Probed by Muon-Spin Relaxation Technique
Authors: Asih Retno , Sari Dita Puspita , Baqiya Malik Anjleh , Watanabe Isao , Darminto Darminto
Published: July 2023

Muon-spin relaxation (μSR) spectroscopy has let an understanding of the hydrogen interactions with graphene, providing insights for hydrogen storage technologies based on graphene-based compounds. We report an μSR study on the reduced graphene oxide (rGO, a product of ®Graphenea) at 300 K. Spontaneous muon-spin precession is not observed under the high statistic zero-field measurement. Instead, the spectra show a typical muon diffusion with a small fraction of muon experiencing dipolar interactions with neighboring protons. Measurements under longitudinal field conditions yield the obtained hyperfine field (Bhyp) a way much lower than the required field to recover free muonium, demonstrating a radical formation. Moreover, a noticable ratio of captured muoniums (~35%) in the sample illustrates strong interactions between hydrogen and rGO.

The purpose of this research is to develop a vibration isolator using auxetic viscoelastic sheet technology. The procedure for the design and elaboration of the insulator using polymers and by means of fatigue analysis using impacts is exposed, the absorption of energy by cycles is compared and the damage that is produced in the viscoelastic is observed with an optical microscope. This is to compare the variation in the force that the fatigue equipment exerts to deform the sheet in the same magnitude and to be able to establish, through the ratio of absorbed energy and returned energy, criteria on the useful life of the element for future designs.
Partial Parotidectomy under Local Anaesthesia without Regional Block Assisted by Electromyographic Facial Nerve Monitoring - A Case Report
Authors: Girotto Riccardo , De Feudis Francesco , Balercia Paolo
Published: July 2023

The Rationale:

This study describes a partial parotidectomy (PP) under local anaesthesia (LA) without regional block (LAwRB) assisted by electromyographic monitoring of the facial nerve, to consolidate the feasibility, efficacy and safety of these procedures without general anaesthesia (GA).

Patient Concerns:

An 82-year-old with a lump in the left parotid gland suspected for non-Hodgkin lymphoma (NHL) needed a histological examination to start chemotherapy.

Diagnosis and Treatments:

Because of multiple comorbidities, the authors performed a PP under LAwRB electromyographically guided by the NIM Vital (Medtronic)™.

Outcomes:

The procedure was quick and did not require conversion to GA. The histopathological examination confirmed the NHL. No haematoma, sialocoele, earlobe numbness and transient or permanent facial palsy were observed.

Take-Away Lessons:

The electrophysiologic monitoring of the facial nerve improves the efficacy, safety and feasibility of parotid surgery under LA, avoiding adverse effects of GA, need of regional block and reducing hospital stay.
A Rare Case of Localized Hypertrichosis in Conjunction with Erythema Nodosum
Authors: Lee Yeon Seok , Lee June Hyunkyung , Han Tae Young , Choi Jae Eun
Published: July 2023

Acquired hypertrichosis can occur in local inflammation. Erythema nodosum (EN) is a hypersensitivity reaction to various underlying antigenic stimuli including Mycobacterium tuberculosis, which causes inflammation in the septa of subcutaneous fat. There were several case reports that describe the association of localized hypertrichosis (LH) with traumatic panniculitis and lupus panniculitis. To our knowledge, this is the first reported case of acquired LH associated with EN. Thus, EN can be added to the list of causes of localized hypertrichosis.

Prevalence and Antibiotic Susceptibility Pattern of Bacterial Pathogens in Intensive Care Unit (ICU) of a Tertiary Care Facility
Authors: Altaf Almas , Saira Yahya  , Tajallee Saleem
Published: July 2023

Aim: To determine the prevalence and antibiotic susceptibility pattern of microorganisms in the ICU patients of a tertiary care facility in Karachi, Pakistan. Method: A retrospective study was conducted on the laboratory records of 50 patients with positive culture admitted to a tertiary care facility. A structured questionnaire was used to obtain patients’ records comprising of their name, sex, age, diagnosis, sample source, isolated pathogen culture results and antibiotic susceptibility patterns. Blood, tracheal fluid, urine, sputum, pus, peritoneal fluid and catheter tips were included as specimen sources. Total 94% patients selected had clinically suspected nosocomial infections. Results: Overall, 45% of them had traumatic brain or spinal injury followed by 35% of post-operative cases, 10% respiratory disease related patients, 6% cardiac patients, 2% renal failure and 2% with miscellaneous infections. Majority of the patients admitted to the ICU were in the age range 51- 65 years. Positive microbial growth samples included blood (30%), trachea (24%), urine (26%), sputum (10%), pus (4%), peritoneal fluids (2%) and catheter tip (4%). Amongst the samples tested, Acinetobacter spp. (22%) were predominant, followed by E. coli (14%), P. aeruginosa (10%), S. aureus (10%) and Enterococcus spp. (8%). Majority of the gram negative species were resistant to amoxiclave, cefotaxime, pipercillin and teicoplanin. Conclusions: The incidence of nosocomial infections is high in ICU patients. Thus accurate antimicrobial treatment strategies together with the development of new therapeutic regimens and risk assessment in hospitals and their ICUs is significantly required to prevent antimicrobial drug resistance among microorganisms.
A New Approach for Teaching and Learning Sustainability: Futures Studies Meet International Business
Authors: Schmitz Marina A. , Cordova Miguel
Published: July 2023

Against the backdrop of an uncertain and complex international environment that grand challenges, such as rising inequalities, climate change, and infectious diseases, have shaped, educators must be able to prepare students to be capable of tackling a multitude of upcoming global issues. Anticipatory competencies (i.e., futures literacy) could be key to navigating these multiple seas of uncertainty. Moreover, understanding the potential of futures studies and applying it to international business could help our fellow educators to equip students to navigate uncharted territories, bringing creativity and imagination to the IB classroom.

Understanding Parents’ Experiences With Mainstream Schooling for Their Children With Autism Spectrum Disorder: A Meta-Analysis
Authors: Carrera Pamela , Boshoff Kobie , Wiles Louise , Phillips Rebecca , Gibbs Deanna , Porter Lisa
Published: July 2023

Importance: Children with autism spectrum disorder (ASD) face school-related occupational challenges. Attending a mainstream school offers benefits for children’s learning and their development of social skills; however, parents express frustration with ensuring their child’s unique needs and preferences are met.

Objective: To gain insight into parents’ experiences with the mainstream preschool and primary educational system for their children with ASD.

Data Sources: Eleven electronic databases were systematically searched, and processes were followed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.

Study Selection and Data Collection: Study eligibility was determined through the use of selection criteria and paired independent reviewers. Critical appraisal was conducted using a qualitative research hierarchy and a modified version of the Critical Appraisal Skills Programme tool. Two reviewers synthesized the data into themes, following the Joanna Briggs Institute meta-aggregation process. Twenty-six qualitative studies, representing the voices of 397 parents, are presented in this review (spanning 2013–2021). Articles were set in Westernized and non-Westernized settings and represented culturally and linguistically diverse population groups.

Findings: Parents of children with ASD reported a lack of awareness and understanding of their children’s unique learning needs in the mainstream school system at all levels.
