Scholarly Interest in Forest Fires in Indonesia: A Bibliographical Review
Authors: Wulandari Eka , Mardiatno Djati , Susilastuti Dewi Haryani , Maryudi Ahmad
Published: August 2022

Forest fires in Indonesia have attracted much attention among researchers over the past few decades. This paper aims to systematically map the existing corpus of scientific knowledge on forest fires in Indonesia. The systematic maps visualize which areas of significant activity and indicate specific interests and motives. The systematic analysis is also helpful in improving the understanding of current issues, problems, and challenges. From the scientific database of Scopus, we found 209 peer-reviewed journal articles directly related to forest fires in Indonesia published between 1989 and 2021 (July). In general, the number of publications rose after major fire events, notably in 1997/1998. The El Nino Southern Oscillation (ENSO)-related big fires seem to be the primary driver of more scientific inquiries. The present review shows that although fires occurred throughout the year, they mainly occurred in the dry season, indicating the crucial role of weather even though it is not the direct cause of fire ignition. Our research shows that all types of forest functions in Indonesia have experienced fires, but approximately half of the studied fires occurred in conservation areas. More specifically, previous studies have been more dedicated to secondary forests. The studies generally pointed out that secondary forests are more prone to fires. More than a half of the existing scientific work was looking at human-induced fires, although natural hazards drove that came close. Regarding human-induced drivers, most research was dedicated to the links between fires and the use of fires in land preparation for both small-scale agricultural activities and commercial plantations. The impacts of forest fires have been the most studied topic among scholars on fires in Indonesia. More specifically, the existing research was focused on the ecological/ environmental effects dominated by studies on the impacts of air quality and biodiversity. Interestingly, the existing research rarely addressed other issues, such as local livelihoods and how they adapt to environmental changes.
Writing science in urgent times: CoViD-19 and its impact on scientific writing
Authors: Puente-Castelo Luis , Moskowich Isabel
Published: August 2022

The urgent need for new knowledge as a result of the CoViD-19 pandemic has led to a significant increase in the amount of scientific writing on the topic. Various analyses of this phenomenon from different approaches have appeared thus far (Horbach 2020; Torres-Salinas 2020). However, less attention has been paid to the impact of this situation on the language of these studies, looking into whether the continued emergency affects authors’ conscious or unconscious linguistic choices, and if so, how. This article compares texts on CoViD with texts written during the previous MERS emergency and its aftermath, trying to find if texts on CoViD present particular linguistic features reflective of this situation of urgency. Results suggest that texts on CoViD do indeed exhibit particular linguistic features, and that these point to a preference for conveying immediate knowledge and a departure from rhetorical practices common in scientific writing.

As food consumption increases, so does the number of agricultural by-products. That is why it is necessary to find the best possible uses for them, operating by the principles of the bioeconomy. This work aims to gather information on the possibilities of using grain byproducts to develop new products and evaluate which bran products are the most suitable for commercialisation based on economic, environmental, social, and technical factors. Two methods were used in this work: literature review and multi-criteria decision analysis. As a result, 30 products were identified that could be made by using wheat bran, straw, husk, and dust. The products were divided into six groups – packaging materials, building materials, adsorbents, fuel, thermal insulation materials, and chemicals. In multi-criteria decision analysis, it was looked at seven bran products of which the best alternative for further commercialisation is mycelium-based biocomposite.

Vitamin D serum level as a prognostic factor in 1 predicting mortality severe COVID-19 patients: An evidence based case report
Authors: Puspita Heny , Kumala Marcia , Wulandari Yohannessa
Published: August 2022

Introduction: The mortality rate of COVID-19 is still high. Many prognostic factors have been studied to decrease the mortality rate. One of the many factors is vitamin D status, known for years as an immunomodulator and anti-inflammatory agent. Vitamin D deficiency could worsen the symptoms of COVID-19 and ultimately lead to mortality. However, some literature shows controversial results. 

Methods: Literature research was conducted by advanced searching in Pubmed, Cochrane Library, Scopus, and ProQuest, using a combination of both MeSH Terms and Title/Abstract. After removing duplicates, these literature were screened according to the eligibility criteria. Appraisal and level of evidence of the final literature were determined based on Oxford Centre for Evidence-Based Medicine.

Results: Two selected literature were relevant to answer our clinical question. The former is a retrospective cohort study by Radujkovic et al. (2020), while the latter is a prospective cohort study by Bennouar et al. (2020). Both show similar results that low vitamin D serum levels in severe COVID-19 patients can increase the in-hospital mortality risk.

Conclusion: Vitamin D is one of the prognostic factors that can predict the mortality rate of severe COVID-19 patients. We suggest that vitamin D serum level can be measured regularly in COVID-19 patients and administered to patients with such deficiencies. Adequate vitamin D deficiency management is expected to lower the COVID-19 mortality rate.

Authors: Theresia Gracia Natalia , Sudarma Verawati
Published: August 2022

Stunting is a multifactorial condition where a toddler has less body length compared to their age. One of the factors is the immunization status of children, which can lead to susceptibility to infection and caused growth disturbance. This study was conducted to determine whether immunization plays a role as one of the interventions to prevent stunting in children age 1-5 years by using cross-sectional observational study with a total of 110 children aged 1-5 years who visited the Public Health Center of Jatinegara District, East Jakarta between September-November 2019. Questionnaires, anthropometric assessment using body length board and microtoice, and Z-score assessment were obtained during the study. The Chi-square test was performed for data analysis. The result of this study showed that 47,3% of respondents had incomplete immunization status, and 84.6% of child were stunted. Immunization plays a role as one of the factors preventing stunting in children age 1-5 years (p<0,001). It can be concluded that immunization is one of the factors contributing to lowered incidence of stunting in children age 1-5 years.

Published: August 2022

Pulmonary tuberculosis (pulmonary TB) is a chronic infectious disease with high levels of morbidity and mortality. Metabolic changes due to tuberculosis Mycobacterium infection and activation of the neurohormonal system contribute to the occurrence of malnutrition, which can have a negative effect on the prognosis of patients with pulmonary TB, as well as decreased functional capacity and quality of life. The provision of medical nutrition therapy from the beginning of diagnosis is upheld, supporting the recovery process of TB patients. In this series of cases, there were four cases of Pulmonary TB patients with difficulty, namely TB billion, chronic obstructive pulmonary disease (COPD), and meningitis TB. At the beginning of the examination, there was a deficiency of macronutrients and micronutrients, hypoalbuminemia, anemia, and decreased functional capacity and quality of life. Medical nutrition therapy is administered individually, according to clinical conditions such as TB with mild, moderate and severe malnutrition, those are gradually weight loss and muscle wasting when the symptoms start until treated in intensive care unit (ICU) and hospital ward. According to laboratory parameters such as anemia, hypoalbuminemia, and a history of food intake analysis such as hypocaloric and starvation.

Authors: Rathod Santosh , Jadav Khushbu Harshadkumar , Ambasana Akshay , Moliya Puja , Jagati Ashish
Published: August 2022

Hereditary angioedema (HAE) is a rare disease characterized by recurrent non-pitting subcutaneous edema, involving skin and mucosa of the upper respiratory tract and intestine. Approximately half of the cases manifest clinically in childhood. Due to the rarity of the condition, general practitioners may not be aware of this condition and hence every angioedema attack is managed with systemic steroids. Confirmation of the diagnosis and counseling of the family is also required for education of caregivers and emergency assistance for avoidance of triggering factors (trauma, mental stress, and infection) and prompt control of edematous attacks. We present a case of an 11-year-old child having HAE with recurrent episodes of swelling of face with family history positive and low level of C1 esterase inhibitor, C4 which was managed with systemic use of tranexamic acid.

Published: August 2022

Randomized controlled trials (RCTs) have become the standard method of evaluating new interventions (whether medical or surgical), and the best evidence used to inform the development of new practice guidelines. When we review the history of medical versus surgical trials, surgical RCTs usually face more challenges and difficulties when conducted. These challenges can be in blinding, recruiting, funding, and even in certain ethical issues. Moreover, to add to the complexity, the field of neurosurgery has its own unique challenges when it comes to conducting an RCT. This paper aims to provide a comprehensive review of the history of neurosurgical RCTs, focusing on some of the most critical challenges and obstacles that face investigators. The main domains this review will address are: (1) Trial design: equipoise, blinding, sham surgery, expertise-based trials, reporting of outcomes, and pilot trials, (2) trial implementation: funding, recruitment, and retention, and (3) trial analysis: intention-to-treat versus as-treated and learning curve effect.
Choroid plexus carcinoma in two siblings, with a novel genetic mutation in TP53 – A case report and review of literature
Authors: Vasudevan Ramesh C. , Vayalipath Shameej K.
Published: August 2022

Background:

Choroid plexus carcinoma (CPC) is an uncommon aggressive neuroectodermal-derived childhood brain malignancy with a dismal prognosis, especially when tumor protein p53 (TP53) mutations or malfunctions are present. The occurrence of these cancers is linked to germline and somatic anomalies at a number of genetic loci. We present a case report of CPC in two siblings which was found to be linked to a unique genetic mutation of TP53 in heterozygous state in both the father and the patient.

Case Description:

A 2-year-old female child presented with a history of vomiting, headache, and seizures. A brain magnetic resonance imaging discovered a large-sized lesion in the left lateral ventricle with infiltration to surrounding brain parenchyma suggestive of aggressive choroid plexus neoplasm. Her only sibling (sister) died of CPC 1 year ago. Her parents are apparently healthy with no history of the central nervous system malignancies in the maternal and paternal sides. Since two children in a family were affected with CPC, genomic profiling of parents and patients was done. A novel frameshift variant c.72dupA,p. (Leu25Thrfs Ter4) was observed in exon 2 of TP53 in a heterozygous state in the proband. This variant was observed in her father in the heterozygous state.

Conclusion:

CPC affecting siblings, associated with novel frameshift mutation in TP53 and inherited in an autosomal dominant pattern, is a rare entity. It has importance in genetic counseling and planning targeted molecular treatment. Genetic profiling is important for prognostication, as P53 pathway dysfunction carries a dismal prognosis, especially when it is associated with Li-Fraumeni syndrome.
Panhypopituitarism caused by an unruptured giant cavernous internal carotid artery aneurysm compressing the pituitary gland treated with a flow-diverting stent: A case report
Authors: Oikawa Nozomu , Misaki Kouichi , Aono Daisuke , Nambu Iku , Hayashi Yasuhiko , Uchiyama Naoyuki , Nakada Mitsutoshi
Published: August 2022

Background:

Internal carotid artery (ICA) aneurysms extending into the intrasellar region that mimics pituitary tumors and leads to pituitary dysfunction are relatively rare. The treatment for aneurysms includes surgery and endovascular procedures. However, functional recovery of the pituitary gland is difficult.

Case Description:

We report a case of a 43-year-old woman who presented with severe headaches and generalized malaise. Magnetic resonance imaging (MRI) revealed a giant unruptured cavernous ICA aneurysm that pushed the pituitary stalk contralaterally. A baseline endocrinological examination suggested panhypopituitarism. Hypopituitarism was treated with hormone replacement therapy, which improved the patient’s symptoms of headaches and malaise after 4 days. The aneurysm was treated using a pipeline flow-diverting stent. Two years later, the aneurysm had reduced to half of its maximum diameter, and the pituitary stalk was visible on MRI. Hormone loading tests 1 week postoperatively showed almost no response. At postoperative 6 months, there was a trend toward improvement.

Conclusion:

Flow-diverting stent deployment is useful for large or giant carotid artery aneurysms with pituitary gland compression.
Spinal epidural arteriovenous fistula with improved sphincter impairment detected by intraoperative neurophysiological monitoring
Authors: Shima Shogo , Tanaka Yasuko , Sato Shinsuke , Niimi Yasunari
Published: August 2022

Background:

A spinal epidural arteriovenous fistula (SEAVF) is a rare type of arteriovenous shunt that occurs mainly in the thoracic or lumbar spine. Patients with SEAVF develop motor/sensory disturbances of the lower extremities and sphincter dysfunction. Among these symptoms, sphincter impairments show less improvement than others, and its relevance to neurophysiological monitoring has not been documented.

Case Description:

A 77-year-old woman presented with progressive motor weakness and numbness in the lower extremities and urinary and fecal incontinence. Spinal magnetic resonance imaging showed spinal cord edema in Th5-Th11 and enlarged perimedullary veins. We performed spinal angiography and endovascular treatment under intraoperative neurophysiological monitoring (IOM), including sensory evoked potential (SEP), motor evoked potential (MEP), and bulbocavernosus reflex (BCR) monitoring. Diagnostic angiography revealed a SEAVF with perimedullary venous drainage fed by the left L2 segmental artery. The shunt was completely embolized using N-butyl-2-cyanoacrylate. Although SEP and MEP of the lower legs were recordable during treatment, anal MEP and BCR were not observed. The sphincter symptoms improved 1.5 years after the treatment. Follow-up angiography revealed no shunt recurrence and improved venous congestion. Anal MEP and BCR were detected during angiography, indicating neurophysiological improvement in sphincter function. The prolonged latency of the monitoring suggested a pudendal nerve injury.

Conclusion:

This case report first described improvement of the IOM correlated with the functional recovery of sphincters after embolization of a SEAVF. Follow-up neurophysiological monitoring is important to assess the functional recovery of the sphincter.
Bioconversion of waste lubricant oil by Achromobacter xylosoxidans PSA5 employing a Central Composite Design approach for enhanced biosurfactant production
Authors: Kopalle Parimala , Pothana Shanmukha Anand
Published: August 2022

A biosurfactant producing bacterial strain was isolated from oil-contaminated soils in Visakhapatnam, India and identified as Achromobacter xylosoxidans PSA5 by 16S rRNA sequencing. The Central Composite Design of Response Surface Methodology was deployed in the present study to ascertain the optimum conditions for producing biosurfactant from A. xylosoxidans PSA5. A temperature of 35°C, pH 7.0, 2.0% waste lubricant oil and a five-day incubation time were found to be optimal for biosurfactant production with a maximum emulsification index of 60.0%. Under optimum conditions, 4.46 g/L of the biosurfactant was produced which was 4.5 times higher than the yield obtained under unoptimized conditions. The kinetic study showed that biosurfactant production was growth-associated, signifying that biosurfactant is a primary metabolite. Partial characterization of the biosurfactant by thin-layer chromatographic analysis revealed that the putative biosurfactant was of glycolipid type.

Published: August 2022

The Jahn–Teller effect, a phase transition phenomenon involving spontaneous breakdown of symmetry in molecules and crystals, causes important physical and chemical changes that impact various fields of science, from the natural photosystem II to superconductors. In this study, we discovered that localised surface plasmon resonance (LSPR) induced the cooperative Jahn–Teller effect in covellite CuS nanocrystals (NCs), causing metastable displacive ion movements. Although light–matter interaction of plasmonic metal NCs has been widely investigated, the scope has been limited to collective mode stimulation. Electron diffraction measurements under photo illumination, ultrafast time-resolved electron diffraction analyses, and theoretical calculations of semiconductive plasmonic CuS NCs showed that metastable displacive ion movements due to the LSPR-induced cooperative Jahn–Teller effect caused a delay in the relaxation of LSPR in the microsecond region. Furthermore, the displacive ion movements caused photo-switching of conductivity in CuS NCs films used in room temperature ranges such as in transparent variable resistance infrared sensors. This study pushes the limits of plasmonics from the increase in tentative collective oscillation to metastable crystal structure manipulation, thereby expanding on Faraday's discovery.

Published: August 2022

Thermoset polymers and fiber-reinforced polymer composites possess the chemical, physical, and mechanical properties necessary for energy-efficient vehicles and structures, but their energy-inefficient manufacturing and the lack of end-of-life strategies render these materials unsustainable. Here, we demonstrate end-of-life deconstruction and upcycling of high-performance poly(dicyclopentadiene) (pDCPD) thermosets with a concurrent reduction in the energy demand for curing via frontal copolymerization. Triggered material deconstruction is achieved through cleavage of cyclic silyl ethers and acetals incorporated into pDCPD thermosets. Both solution-state and bulk experiments reveal that seven- and eight-membered cyclic silyl ethers and eight-membered cyclic acetals incorporate efficiently with norbornene-derived monomers, permitting deconstruction at low comonomer loadings. Frontal copolymerization of DCPD with these tailored cleavable comonomers enables energy-efficient manufacturing of sustainable, high-performance thermosets with glass transition temperatures greater than 100 °C and elastic moduli greater than 1 GPa. The polymers are fully deconstructed, yielding hydroxyl-terminated oligomers that are upcycled to polyurethane-containing thermosets with higher glass transition temperatures (ca. 158 °C) than the original polymer upon reaction with diisocyanates. This approach is extended to frontally polymerized fiber-reinforced composites, where high fiber volume fraction composites (Vf = 65%) containing a cleavable comonomer are deconstructed and the reclaimed fibers are used to regenerate composites via frontal polymerization that display near identical properties compared to the original. This work demonstrates that the use of cleavable monomers, in combination with frontal manufacturing, provides a promising strategy to address sustainability challenges for high-performance materials at multiple stages of their lifecycle.

Published: August 2022

Aqueous organic redox flow batteries (AORFBs) hold great promise for safe, sustainable, and cost-effective grid energy storage. However, developing catholyte redox molecules with desired energy density, power, and stability simultaneously has long been a critical challenge for AORFBs. Here, we report a novel class of ionic liquid mimicking TEMPO dimers (i-TEMPODs) that can be produced by our newly developed building block assembly synthetic platform. By systematically investigating 21 derivatives, we reveal i-TEMPODs have optimized size and charge that is compatible with highly conductive membrane and can form a “water-in-catholyte” (WiC) state. The tight coordination dynamics with water molecules deliver extreme solubility with promoted electrochemical stability at highly positive potentials. Leveraging these advances, we identify a champion molecule and demonstrate record overall AORFB performance in energy density (47.3 Wh/L), power density (0.325 W/cm2), and stability (no apparent capacity decay after 96 days) with low-cost and scalable chemistry.
Comprehensive Evaluation of End-Point Free Energy Techniques in Carboxylated-Pillar[6]arene Host-guest Binding: II. Regression and Dielectric Constant
Authors: Liu Xiao , Zheng Lei , Cong Yalong , Gong Zhihao , Yin Zhixiang , Zhang John , Liu Zhirong , Sun Zhaoxi
Published: August 2022

End-point free energy calculations as a powerful tool have been widely applied in protein-ligand and protein-protein interactions. It is often recognized that these end-point techniques serve as an option of intermediate accuracy and computational cost compared with more rigorous statistical mechanic models (e.g., alchemical transformation) and coarser molecular docking. However, it is observed that this intermediate level of accuracy does not hold in relatively simple and prototypical host-guest systems. Specifically, in our previous work investigating a set of carboxylated-pillar[6]arene host-guest complexes, end-point methods provide free energy estimates deviating significantly from the experimental reference, and the rank of binding affinities is also incorrectly computed. These observations suggest the unsuitability and inapplicability of standard end-point free energy techniques in host-guest systems, and alteration and development are required to make them practically usable. In this work, we consider two ways to improve the performance of end-point techniques. The first one is the PBSA_E regression that varies the weights of different free energy terms in the end-point calculation procedure, while the second one is considering the interior dielectric constant as an additional variable in the end-point equation. By detailed investigation of the calculation procedure and the simulation outcome, we prove that these two treatments (i.e., regression and dielectric constant) are manipulating the end-point equation in a somehow similar way, i.e., weakening the electrostatic contribution and strengthening the non-polar terms, although there are still many detailed differences between these two methods. With the trained end-point scheme, the RMSE of the computed affinities is improved from the standard ~12 kcal/mol to ~2.4 kcal/mol, which is comparable to another altered end-point method (ELIE) trained with system-specific data. This phenomenon along with the extremely efficient optimized-structure computation procedure suggests the regression (i.e., PBSA_E as well as its GBSA_E extension) as a practically applicable solution that brings end-point methods back into the library of usable tools for host-guest binding. However, the dielectric-constant-variable scheme cannot effectively minimize the experiment-calculation discrepancy for absolute binding affinities, but is able to improve the calculation of affinity ranks. This phenomenon is somehow different from the protein-ligand case and suggests the difference between host-guest and biomacromolecular (protein-ligand and protein-protein) cases. Therefore, the spectrum of tools usable in protein-ligand cases could be unsuitable for host-guest binding, and numerical validations are necessary to screen out really workable solutions in these ‘prototypical’ situations.

The bioactive compounds from plant extract represent a potent alternative to combating
the increasing antimicrobial resistance (AMR) to synthetic drugs. This study aimed to
investigate the phytochemical, and antibacterial activities of Morinda lucida. Leaves of M.
lucida was extracted successively using n-hexane, acetone, methanol and distilled water.
The crude plant extracts were evaluated for their antibacterial activity against pathogens
found in food and other sources such as Staphylococcus aureus, Bacillus subtilis,
Pseudomonas aeruginosa, Salmonella enterica serovar Typhi, Escherichia coli, and
Klebsiella spp. using the agar well diffusion technique. Minimum inhibitory concentration
(MIC) was carried out using the microbroth dilution technique. The phytochemical
analysis showed the presence of alkaloids and sterols in all extracts. Flavonoid was only
present in the n-Hexane extract. The result showed that n-Hexane extract had the widest
zone of inhibition against P. aeruginosa - 13.67 mm (12.5 mg/mL MIC), B. subtilis - 15
mm (12.5 mg/mL MIC), while acetone extract was most active against S. enterica ser.
Typhi - 24.67 mm (6.25 mg/mL MIC), S. aureus - 24.83 mm (3.13 mg/mL MIC), E. coli -
13.33 mm (1.56 mg/mL MIC) and Klebsiella spp. - 18.33 mm (12.5 mg/mL MIC). These
findings indicated that n-Hexane and acetone extract of M. lucida exhibited significant
antimicrobial activity. Therefore, further research should be carried out to isolate the
bioactive compounds with potentials in developing new drug leads against drug-resistant
microbial strains.

Religious character is an important thing that must be instilled in students in current developments, especially in elementary school (SD) settings. Efforts to develop learning media related to religious characters have been carried out, one of which is based on information technology. Learning media innovations that are developed must pay attention to creative content packaging so that students can easily understand the material presented. Implementation in the field shows that the mastery of information technology in SDN Tanon 2 teachers is not optimal. The teacher has a strong motivation to learn to make learning media but there is no accompanying facilitator. Of course, this will affect the media content and the process of delivering maximum material to students. From this problem, a scheduled training forum for elementary school teachers is needed to develop good and interesting learning media. The method of service activities is carried out by carrying out webinar series activities, training in making learning media, and evaluation. The results of the service activities show that the trainees can improve competence in developing learning materials with the Canva application.

The present study was performed for evaluating the anti-diabetogenic effect of chirata extract in alloxen induced rat model which has rarely been done by any researcher previously. Diabetes was induced by injecting Alloxen (ALX) @ 120 mg/kg body weight subcutaneously to swiss albino mice. The sixteen rats were divided into four groups named Group A (non-diabetic) for the negative control, Group B (diabetic) for positive control, Group C treated with aqueous extract of chirata@ 125 mg/kg body wt and Group D treated with metformin (anti-diabetic drugs) @150 mg/kg body wt.). The duration of the experiment was 16 (sixteen) days. Finally, the research showed that the final body weight of positive control (diabetes induction) Group B (43.0±0.90) was significantly decreased from the treatment of negative control Group A (43.5±1.80) and similarly followed by treatment with a synthetic anti-diabetic agent such as metformin group D (44.50±1.70) and herbal drugs as chirata treatment Group C (44.0±1.95). The creatinine level in Group A, B, C and D were 0.85±0.07 mg/dL, 1.15±0.07 mg/dL, 0.95±0.08 mg/dL and 0.9±0.14 mg/dL respectively. The SGPT level in Group A, B, C, and D was 19±1.41 U/L, 27.44±2.82 U/L, 26.5±2.12 U/L, and 20.5± 2.12 U/L respectively. The SGOT level in Group A,B,C and D were 30±2.82 g/dL, 90±3.53 g/dL, 70±1.41 g/dL and 45±2.83 g/dL respectively. In alloxen-induced mice, a fall in SGPT levels was observed in the groups treated with aqueous extract of Chirata and Metformin. Aqueous extract of Chirata decreased SGOT levels compared with a diabetic control group. The body weight of the swiss albino mice was increased significantly in those treated with chirata extraction in the diabetic group. The synthetic drug metformin-treated group improved the body weight of the swiss albino mice model. The antihyperglycemic activity of aqueous extract of Chirata is comparatively lower than the synthetic anti-diabetic drugs such as metformin. Thus the above observations suggested that extracts, from Swertia chirata possess anti-diabetic principal and can presumably be used for the treatment of diabetes mellitus.

The evaluation of the food items of red-billed quelea during off-cropping season in Gyawana ecosystem was carried out, to ascertain the wild food of Quelea quelea foraged on during off- cropping season. Red-billed quelea (Q, quelea) devastation of crops continues to be a problem that militates against food security in Adamawa State and other arid regions of Nigeria. The bird appears to have alternative food sources which ensure its survival and breeding during off- cropping seasons. The crop contents of Q, quelea were analysed. Nine (9) different food items were identified including seeds of different grasses, insect remains and Grits from the crops of one hundred and fifty (150) Q, quelea sampled for this study. Echinochloa colonum has the highest frequency and magnitude of occurrence in the food items foraged on by the Q, quelea with a mean value of 40.20±0.72, followed by Digitaria ciliaris (35.33±1.03), Digitaria iburua (29.96±1.12), Setaria pallidofusca (29.33±0.41), Roetboellia exaltata (21.67±0.25), Brachiaria mutica (1.71±0.16) and the least seed consumed is Cenchrus biflorus with a mean of 1.15±0.02. Grits was consumed in small quantity (0.15±0.36) by both sexes, while insects remained was observed only in female’s crop of the Quelea birds. Analysis of variance was used to compare the mean number of various seeds consumed by the Q, quelea during the period of the study. The result shows no significant difference in the food items consumed by Red-billed Quelea during off-cropping season at P >0.05. Based on the findings of this research work, the researchers therefore, recommend that further study should be carryout on the food items of Q, quelea during cropping season and also biological control of this Quelea birds (Q, quelea).
